Detailed ways

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a first embodiment of a menu control method based on a spatial positioning device according to the present invention.

This embodiment proposes a menu control method based on spatial positioning equipment, including:

Step S10, when a space movement event of the positioning device is detected, determine the starting point coordinate information and the end point coordinate information of the positioning device in the detected space movement event;

The positioning device can be an air mouse, and a space positioning module is set on the air mouse to locate the air mouse, which can not only realize the positioning function and send positioning data to the terminal connected to it, but also send control instructions to the terminal. Setting the positioning device as an air mouse is only a specific embodiment of this solution, and the positioning device is not limited to an air mouse. The spatial movement event includes the process from the change of the coordinate information of the positioning device to the stop of the change. When the user moves the positioning device, there are corresponding start position and end position. The start position and end position respectively correspond to the coordinate information. The coordinate information corresponding to the position and the end position is sent to the terminal connected to it, that is, the terminal where the controlled menu is located.

Step S20, determining the moving direction of the positioning device according to the coordinate information of the start point and the coordinate information of the end point;

The menu in the terminal and the starting point coordinate information and end point coordinate information of the positioning device adopt the same plane coordinate system, and the relative position relationship between the plane line and the menu generated according to the acquired starting point coordinate information and end point coordinate information, and the starting point and end point in The position in the coordinate system determines the moving direction of the positioning device, that is, the direction in which the cursor is to be moved in the menu selection. The specific determination process is as follows:

Set the starting point as point A and the terminal point as point B, then set point A as the origin, take the horizontal direction as the X axis, and take the vertical direction as the Y axis, and take the difference between the position data of point B and point A to point B Locate to the corresponding position of the coordinate axis, and calculate the angle of the line connecting point A to point B relative to the positive axis of the X axis to determine the moving direction of the positioning device, for example, the line connecting point A to point B is relative to the X axis The angle of the positive axis is an acute angle, which means that the positioning device rotates counterclockwise.

Step S30, controlling the menu selection cursor according to the preset jump parameters, and jumping from the current menu option to the target menu option according to the determined moving direction.

The jump parameter of the menu selection cursor can be preset. The jump parameter is the number of menu items that differ between the current menu item and the target menu item. For example, if the jump parameter is 2, the menu selection cursor needs to jump to 2 items, such as If the current menu item is the first item, the target menu item is the third menu item in the determined moving direction. When the spatial movement event of the positioning device is detected, the control menu selects the cursor to jump to the target menu option according to the preset jump parameters. When the terminal detects that the user moves the spatial positioning device, the control menu selects the cursor to jump Preset parameters (preset number of items), convenient and fast, do not need to accurately calculate the distance that the cursor needs to move based on the position information of the positioning device.

In this embodiment, the menu can be in various shapes such as a disc shape and a strip shape, and is not limited to a menu of a certain shape. The coordinate information can determine whether the menu selection cursor moves clockwise or counterclockwise. When the menu is long, it can be determined whether the menu selection cursor moves up or down according to the starting point coordinate information and end point coordinate information of the mobile device. A confirmation button can be set on the positioning device. When the confirmation command sent by the positioning device is received, the screen will be switched to the information corresponding to the menu item pointed by the menu selection cursor, or the information corresponding to the menu item pointed to by the menu selection cursor will be displayed. For the corresponding sub-menu items, when the menu is disc-shaped, a disc-shaped sub-menu concentric with the main menu can be generated on the periphery of the main menu, and the sub-menu can also be displayed in other ways and limited to the above scheme.

The menu control method based on the spatial positioning device proposed in this embodiment only needs to determine the moving direction of the positioning device according to the start point coordinate information and the end point coordinate information of the positioning device when a movement event of the positioning device is detected, and then according to the preset The jump parameter controls the menu selection cursor, and jumps from the current menu option to the target menu option according to the determined moving direction, without accurately obtaining the location information of the positioning device, generating the moving distance and direction according to the determined location information, and controlling the menu The process is simpler and more accurate.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a second embodiment of a menu control method based on a spatial positioning device according to the present invention.

Based on the first embodiment, the second embodiment of the menu control method based on the spatial positioning device of the present invention is proposed. In this embodiment, when the spatial movement event of the positioning device is detected, the method includes:

Step 40, determining the starting point coordinate information and end point coordinate information of the positioning device in the detected spatial movement event and the time interval of the spatial movement event;

Step 50: Determine the moving direction of the positioning device according to the coordinate information of the start point and the coordinate information of the end point, and determine the jump parameter corresponding to the detected spatial movement event according to the mapping relationship between the preset time interval and the jump parameter ;

Step 60, control the menu selection cursor according to the determined jump parameter, and jump from the current menu option to the target menu option according to the determined moving direction.

Taking the disc-shaped menu as an example to illustrate, the time taken by the user to rotate the positioning device for one week can be obtained in advance, and the obtained time can be divided by the number of items in the disc-shaped menu to obtain the time required to jump to a menu item, then Different time intervals correspond to different jump parameters (that is, the number of jump menu items), and the time interval is proportional to the jump parameters. As shown in Figure 7, if it takes 4S to rotate the positioning device for one week, and the number of menu items on the disc-shaped menu is 8, the time required to jump to a menu item is 0.5S. If the detected space If the time interval of the moving event is 2.0S, the number of menu items to be jumped to is 4 items. If the menu item where the menu selection cursor is currently located is menu A, then the target menu position after jumping to 4 items is menu D. The target position of the menu selection cursor is accurately determined according to the acquired spatial movement event time interval. When the time interval of the detected spatial movement event is not directly proportional to the time required to jump to a menu item, a rounding scheme is used, for example, the obtained time interval is 2.2, which is the same as the time required to jump to a menu item The time is 0.5S and the ratio is 4.2, then the number of menu items to jump to is 4 items, that is, the jump parameter is 4 items, or when the obtained time interval is 2.4, the time interval is equal to the time required to jump to a menu item The time is 0.5S and the ratio is 4.8, then the number of menu items to jump to is 5 items, that is, the jump parameter is 5 items. In this embodiment, the mapping relationship between the time interval and the beating parameter can also be the mapping relationship between the time interval interval and the beating parameter, for example, the beating parameter corresponding to the time interval 2S-2.25S is 5S, and the beating parameter corresponding to 2.25S-3S for 6S.

In this embodiment, the threshold T1 of the time interval can be preset. When the time interval of the detected space movement event is less than T1, it is considered that the detected space movement event is invalid and no operation is performed. When the time interval of the received spatial movement event is greater than or less than T1, the moving direction of the positioning device is determined according to the starting point coordinate information and the ending point coordinate information of the mobile device, and the detection is determined according to the mapping relationship between the preset time interval and the jump parameter. The jump parameter corresponding to the detected spatial movement event controls the menu selection cursor according to the determined jump parameter, and jumps from the current menu option to the target menu option according to the determined moving direction.

In this embodiment, this solution can also be, when the coordinate information of the positioning device is detected to change, the position information of the starting point and the end point of the positioning device within the preset time interval is obtained, and according to the position information of the starting point and the end point of the positioning device Determine the moving direction of the positioning device (such as clockwise), and control the menu selection cursor according to the preset jump parameters, jump from the current menu option to the target menu option according to the determined moving direction, the preset time interval and preset corresponding to the jump parameter, and so on, after the menu selection cursor jumps to the target menu option, if the coordinate information of the positioning device is detected to change, continue to obtain the position information of the starting point and end point of the positioning device within the preset time interval , and determine the moving direction of the positioning device according to the position information of the starting point and the end point of the positioning device, until the detected coordinate information of the positioning device no longer changes, and after multiple jumps, the menu selection cursor jumps to the user's desired jump target position of the rotation. The preset time interval is preferably the time required to jump to a menu item, then the corresponding preset jump parameter is 1 item, and the preset jump parameter is proportional to the preset time interval, and the preset The time interval is set to N times the time required to jump to a menu item, and the corresponding preset jump parameter is N items. In this embodiment, the mapping relationship between the time interval and the movement distance threshold can be preset. After obtaining the location information of the starting point and the end point of the positioning device within the preset time interval, the movement distance of the positioning device within the preset time interval can be obtained. Straight-line distance. If the straight-line distance moved by the positioning device is less than the movement distance threshold corresponding to the preset time interval, the operation will be considered invalid and no response will be made.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a third embodiment of a menu control method based on a spatial positioning device according to the present invention.

Based on the first embodiment, the third embodiment of the menu control method based on the spatial positioning device of the present invention is proposed. In this embodiment, when the spatial movement event of the positioning device is detected, the method includes:

Step 70, determining the starting point coordinate information and the ending point coordinate information of the positioning device in the detected spatial movement event;

Step 80, according to the coordinate information of the start point and the coordinate information of the end point, determine the straight-line distance and the direction of movement of the positioning device;

Step 90, according to the mapping relationship between the preset linear distance and the jump parameter, determine the jump parameter corresponding to the detected spatial movement event;

Step 100, control the menu selection cursor according to the determined jump parameter, and jump from the current menu option to the target menu option according to the determined moving direction.

Take the disc-shaped menu as an example for illustration. The radius of the arc formed by the user rotating the positioning device for one circle can be obtained in advance. According to the obtained arc radius and the number of menu items in the disc-shaped menu, a jump can be calculated. The straight-line distance corresponding to the menu item is the straight-line distance between the starting point and the end point of the positioning device when jumping to a menu item. Different straight-line distances correspond to different jump parameters, that is, the number of jump menu items. The straight-line distance is proportional to the jump parameter. Proportional. If the radius of the arc formed by the user turning the positioning device for one circle is R, and the number of menu items in the disc menu is N, then the calculation formula for the straight-line distance L corresponding to jumping to a menu item is: L=2Rsin( 360°/2N), the rotation distance L corresponding to different jump parameters can be calculated according to this formula, and stored in the memory of the terminal. Different rotation distances L correspond to different jump parameters. When determining the moving line of the positioning device After the distance, obtain the jump parameters of the current positioning device according to the mapping relationship between the pre-stored linear distance and the jump parameters, and control the menu selection cursor according to the determined jump parameters, and jump from the current menu option to the target menu according to the determined moving direction option. When setting the mapping relationship between the straight-line distance and the jump parameter, the range of the straight-line distance that can be set corresponds to the jump parameter.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of a fourth embodiment of a menu control method based on a spatial positioning device according to the present invention.

Based on the third embodiment, the fourth embodiment of the menu control method based on the spatial positioning device of the present invention is proposed. In this embodiment, step 100 is replaced by:

Step 110, if the determined straight-line distance is greater than or equal to the first preset threshold, then determine the jump parameter corresponding to the detected spatial movement event according to the mapping relationship between the preset straight-line distance and the jump parameter.

In the movement event of the positioning device, the threshold value of the linear distance moved by the positioning device can be preset, and when the linear distance moved by the positioning device is greater than or equal to the preset threshold value, the user's movement event will be responded to. When a movement event of the positioning device is detected, sometimes the user just moves the positioning device without controlling the menu by moving the positioning device. If the straight-line distance is small, then the detected spatial movement event is considered invalid and the movement event of the positioning device is not responded to, so as to ensure the accuracy of menu control.

In the first embodiment, when the spatial movement event of the positioning device is detected, the linear distance moved by the positioning device can be obtained at the same time when determining the starting point coordinate information and the end point coordinate information of the positioning device in the detected spatial movement event , judging whether the linear distance moved by the positioning device is greater than or equal to the preset threshold, and if the linear distance moved by the positioning device is greater than or equal to the preset threshold, respond to the spatial movement event of the positioning device, that is, determine according to the starting point coordinate information and the ending point coordinate information The moving direction of the positioning device, and control the menu selection cursor according to the preset jump parameters, jump from the current menu option to the target menu option according to the determined moving direction, if the linear distance moved by the positioning device is less than the preset threshold, Then it does not respond to the detected spatial movement event of the positioning device, that is, does not perform any operation.

Referring to FIG. 5 , FIG. 5 is a schematic flowchart of a fifth embodiment of a menu control method based on a spatial positioning device according to the present invention.

Based on the first embodiment, the fifth embodiment of the menu control method based on the spatial positioning device of the present invention is proposed. In this embodiment, after step S20, it also includes:

S120. Determine an angle between the moving direction of the positioning device and a preset ideal moving direction of the positioning device;

S130, if the determined included angle is less than or equal to the second preset threshold, control the menu selection cursor according to the preset jump parameters, and jump from the current menu option to the target menu option according to the determined moving direction.

The user may deviate in the moving direction during the process of moving the positioning device, or the user only places the positioning device or other operations without moving the positioning device to control the menu, then it is necessary to compare the moving direction of the positioning device with the preset ideal The angle between the directions, the preset ideal direction is preferably the ray direction formed by the current menu option and the center point of the target menu option after jumping according to the preset jump parameters, and the first ray and the second ray are determined The angle between them is the deviation when the user moves the positioning device. If the angle is less than or equal to the second preset threshold value, the menu selection cursor is controlled according to the preset jump parameters, and the current menu option jumps according to the determined moving direction. Going to the target menu option, the second preset threshold is preferably 45°. In this embodiment, other ray directions parallel to the first ray are the first ray directions, and the same is true for the second ray directions.

For example, in a long bar menu, if the user moves the positioning device to control the menu selection cursor to move up or down, the angle between the actual moving direction of the positioning device and the vertical direction of the long bar menu is greater than the second preset angle due to misoperation. If the threshold is set, it will not respond to this operation to ensure the accuracy of menu control. Or in the disc-shaped menu, when the user rotates the positioning device clockwise or counterclockwise, there may also be a problem of rotation deviation. In the center of the current menu option and the target menu option after jumping according to the preset jump parameters If the angle between the second ray direction formed by the point and the first ray direction formed by the starting point coordinate information and end point coordinate information of the positioning device is greater than or equal to the second preset threshold value, the operation will not be responded to ensure the accuracy of menu control sex.

In the second embodiment of the menu control method based on the spatial positioning device of the present invention, the mapping relationship between the time interval of the spatial movement event and the ideal rotation direction can be preset, according to the time interval corresponding to the detected spatial movement event of the positioning device In step S40, after determining the start point coordinate information and end point coordinate information of the positioning device in the detected space movement event and the time interval of the space movement event, according to the start point coordinate information and end point coordinate information Determine the moving direction of the positioning device, and determine the ideal rotating direction of the positioning device according to the mapping relationship between the preset spatial movement event time interval and the ideal rotating direction, and determine the gap between the moving direction of the positioning device and the ideal rotating direction If the determined included angle is greater than or equal to the second preset threshold, no response will be made; if the determined included angle is smaller than the second preset threshold, then the detection will be determined according to the mapping relationship between the preset time interval and the jump parameter. Jump parameters corresponding to the detected spatial movement events, and control the menu selection cursor according to the determined jump parameters, and jump from the current menu option to the target menu option according to the determined moving direction.

In the third embodiment of the menu control method based on the spatial positioning device of the present invention, the mapping relationship between the linear distance moved by the positioning device and the ideal moving direction can be preset, and according to the linear distance moved by the positioning device in the detected spatial movement event Determine the corresponding ideal rotation direction. In step S80, after determining the linear distance and moving direction of the positioning device according to the starting point coordinate information and the ending point coordinate information, determine the positioning device according to the mapping relationship between the linear distance and the ideal moving direction The ideal moving direction of the positioning device, and determine the angle between the moving direction of the positioning device and the ideal moving direction, if the determined angle is greater than or equal to the second preset threshold, no response will be made, if the determined angle is smaller than the second preset threshold Set the threshold, and determine the jump parameter corresponding to the detected spatial movement event according to the mapping relationship between the preset linear distance and the jump parameter; control the menu selection cursor according to the determined jump parameter, and move from the current Menu option jumps to the target menu option.

Referring to FIG. 6 , FIG. 6 is a schematic structural diagram of a preferred embodiment of a menu control device based on a spatial positioning device according to the present invention.

This embodiment proposes a menu control device based on spatial positioning equipment, including:

The determining module 10 is configured to, when a spatial movement event of the positioning device is detected, determine the starting point coordinate information and the ending point coordinate information of the positioning device in the detected spatial moving event, and information to determine the direction of movement of the positioning device;

The positioning device can be an air mouse, and a space positioning module is set on the air mouse to locate the air mouse. The air mouse is only a specific embodiment of this solution, and the positioning device is not limited to the air mouse. The spatial movement event includes the process from the change of the coordinate information of the positioning device to the stop of the change. When the user moves the positioning device, there are corresponding start position and end position. The start position and end position respectively correspond to the coordinate information. The coordinate information corresponding to the position and the end position is sent to the terminal connected to it, that is, the terminal where the controlled menu is located.

The menu in the terminal and the starting point coordinate information and the ending point coordinate information of the positioning device adopt the same plane coordinate system, and the relative positional relationship between the plane line and the menu generated by the determination module 10 according to the acquired starting point coordinate information and the ending point coordinate information, and the starting point and the position of the end point in the coordinate system to determine the moving direction of the positioning device, that is, the direction in which the menu selects the cursor to move. The specific determination process is as follows:

Set the starting point as point A and the terminal point as point B, then set point A as the origin, take the horizontal direction as the X axis, and take the vertical direction as the Y axis, and take the difference between the position data of point B and point A to point B Locate to the corresponding position of the coordinate axis, and calculate the angle of the line connecting point A to point B relative to the positive axis of the X axis to determine the moving direction of the positioning device, for example, the line connecting point A to point B is relative to the X axis The angle of the positive axis is an acute angle, which means that the positioning device rotates counterclockwise.

The control module 20 is configured to control the menu selection cursor according to preset jump parameters, and jump from the current menu option to the target menu option according to the determined moving direction.

The jump parameter of the menu selection cursor can be preset. The jump parameter is the number of menu items that differ between the current menu item and the target menu item. For example, if the jump parameter is 2, the menu selection cursor needs to jump to 2 items, such as If the current menu item is the first item, the target menu item is the third menu item in the determined moving direction. When the spatial movement event of the positioning device is detected, the control menu selects the cursor to jump to the target menu option according to the preset jump parameters. When the terminal detects that the user moves the spatial positioning device, the control menu selects the cursor to jump The preset parameters (preset number of items) are very convenient and fast, and there is no need to accurately calculate the distance that the cursor needs to move based on the position information of the positioning device.

In this embodiment, the menu can be in various shapes such as a disc shape and a strip shape, and is not limited to a menu of a certain shape. The coordinate information can determine whether the menu selection cursor moves clockwise or counterclockwise. When the menu is long, it can be determined whether the menu selection cursor moves up or down according to the starting point coordinate information and end point coordinate information of the mobile device. A confirmation button can be set on the positioning device. When the confirmation command sent by the positioning device is received, the screen will be switched to the information corresponding to the menu item pointed by the menu selection cursor, or the information corresponding to the menu item pointed to by the menu selection cursor will be displayed. For the corresponding sub-menu items, when the menu is disc-shaped, a disc-shaped sub-menu concentric with the main menu can be generated on the periphery of the main menu, and the sub-menu can also be displayed in other ways and limited to the above scheme.

In this embodiment, when a spatial movement event of the positioning device is detected, the linear distance moved by the positioning device may be obtained simultaneously when determining the starting point coordinate information and the end point coordinate information of the positioning device in the detected spatial movement event, Judging whether the straight-line distance moved by the positioning device is greater than or equal to the preset threshold, and if the straight-line distance moved by the positioning device is greater than or equal to the preset threshold, respond to the spatial movement event of the positioning device, that is, determine the position according to the starting point coordinate information and the end point coordinate information. Describe the moving direction of the positioning device, and control the menu selection cursor according to the preset jump parameters, and jump from the current menu option to the target menu option according to the determined moving direction. If the straight-line distance moved by the positioning device is less than the preset threshold, then Do not respond to the detected spatial movement event of the positioning device, that is, do nothing.

The menu control device based on the spatial positioning device proposed in this embodiment only needs to determine the moving direction of the positioning device according to the starting point coordinate information and the ending point coordinate information of the positioning device when detecting the movement event of the positioning device, and then according to the preset The jump parameter controls the menu selection cursor, and jumps from the current menu option to the target menu option according to the determined moving direction, without accurately obtaining the location information of the positioning device, generating the moving distance and direction according to the determined location information, and controlling the menu The process is simpler and more accurate.

In the first embodiment of the menu control device based on space positioning equipment of the present invention, the determination module 10 is also used to determine the location in the detected space movement event when the space movement event of the positioning equipment is detected. Starting point coordinate information and end point coordinate information of the device and the time interval of the spatial movement event, and determining the moving direction of the positioning device according to the starting point coordinate information and end point coordinate information, and according to the mapping between the preset time interval and the jump parameter Relationship, determine the jump parameter corresponding to the detected spatial movement event; the control module 20 is also used to control the menu selection cursor according to the determined jump parameter, and jump from the current menu option to the target menu according to the determined movement direction option.

Taking the disc-shaped menu as an example to illustrate, the time taken by the user to rotate the positioning device for one week can be obtained in advance, and the obtained time can be divided by the number of items in the disc-shaped menu to obtain the time required to jump to a menu item, then Different time intervals correspond to different jump parameters, that is, the number of jump menu items, and the time interval is proportional to the jump parameters. As shown in Figure 7, if it takes 4S to rotate the positioning device for one week, and the number of menu items on the disc-shaped menu is 8, the time required to jump to a menu item is 0.5S. If the detected space If the time interval of the moving event is 2.0S, the number of menu items to be jumped to is 4 items. If the menu item where the menu selection cursor is currently located is menu A, then the target menu position after jumping to 4 items is menu D. The target position of the menu selection cursor is accurately determined according to the acquired spatial movement event time interval. When the time interval of the detected spatial movement event is not directly proportional to the time required to jump to a menu item, a rounding scheme is used, for example, the obtained time interval is 2.2, which is the same as the time required to jump to a menu item The time is 0.5S and the ratio is 4.2, then the number of menu items to jump to is 4 items, that is, the jump parameter is 4 items, or when the obtained time interval is 2.4, the time interval is equal to the time required to jump to a menu item The time is 0.5S and the ratio is 4.8, then the number of menu items to jump to is 5 items, that is, the jump parameter is 5 items. In this embodiment, the mapping relationship between the time interval and the beating parameter can also be the mapping relationship between the time interval interval and the beating parameter, for example, the beating parameter corresponding to the time interval 2S-2.25S is 5S, and the beating parameter corresponding to 2.25S-3S The parameter is 6S.

In this embodiment, the threshold T1 of the time interval can be preset. When the time interval of the detected space movement event is less than T1, it is considered that the detected space movement event is invalid and no operation is performed. When the time interval of the received spatial movement event is greater than or less than T1, the moving direction of the positioning device is determined according to the starting point coordinate information and the ending point coordinate information of the mobile device, and the detection is determined according to the mapping relationship between the preset time interval and the jump parameter. The jump parameter corresponding to the detected spatial movement event controls the menu selection cursor according to the determined jump parameter, and jumps from the current menu option to the target menu option according to the determined moving direction.

In this embodiment, the mapping relationship between the time interval of the spatial movement event and the ideal rotation direction can be preset, and according to the ideal rotation direction corresponding to the time interval of the detected spatial movement event of the positioning device, when determining the detected After the start coordinate information and end coordinate information of the positioning device in the spatial movement event and the time interval of the spatial movement event, determine the moving direction of the positioning device according to the start coordinate information and the end coordinate information, and determine the moving direction of the positioning device according to the preset space The mapping relationship between the movement event time interval and the ideal rotation direction determines the ideal rotation direction of the positioning device and determines the angle between the movement direction of the positioning device and the ideal rotation direction. If the determined angle is greater than or equal to the second preset valve If the determined included angle is less than the second preset threshold value, the jump parameter corresponding to the detected spatial movement event is determined according to the mapping relationship between the preset time interval and the jump parameter, and The menu selection cursor is controlled according to the determined jump parameter, and jumps from the current menu option to the target menu option according to the determined moving direction.

In this embodiment, this solution can also be, when the coordinate information of the positioning device is detected to change, the position information of the starting point and the end point of the positioning device within the preset time interval is obtained, and according to the position information of the starting point and the end point of the positioning device Determine the moving direction of the positioning device (such as clockwise), and control the menu selection cursor according to the preset jump parameters, jump from the current menu option to the target menu option according to the determined moving direction, the preset time interval and preset corresponding to the jump parameter, and so on, after the menu selection cursor jumps to the target menu option, if the coordinate information of the positioning device is detected to change, continue to obtain the position information of the starting point and end point of the positioning device within the preset time interval , and determine the moving direction of the positioning device according to the position information of the starting point and the end point of the positioning device, until the detected coordinate information of the positioning device no longer changes, and after multiple jumps, the menu selection cursor jumps to the user's desired jump target position of the rotation. The preset time interval is preferably the time required to jump to a menu item, then the corresponding preset jump parameter is 1 item, and the preset jump parameter is proportional to the preset time interval, and the preset The time interval is set to N times the time required to jump to a menu item, and the corresponding preset jump parameter is N items. In this embodiment, the mapping relationship between the time interval and the movement distance threshold can be preset. After obtaining the location information of the starting point and the end point of the positioning device within the preset time interval, the movement distance of the positioning device within the preset time interval can be obtained. Straight-line distance. If the straight-line distance moved by the positioning device is less than the movement distance threshold corresponding to the preset time interval, the operation will be considered invalid and no response will be made.

In the first embodiment of the menu control device based on space positioning equipment of the present invention, the determination module 10 is also used to determine the location in the detected space movement event when the space movement event of the positioning equipment is detected. The starting point coordinate information and the ending point coordinate information of the device, and according to the starting point coordinate information and the ending point coordinate information, determine the linear distance and the moving direction of the positioning device movement, and determine according to the mapping relationship between the preset linear distance and the jump parameter The jump parameter corresponding to the detected spatial movement event; the control module 20 controls the menu selection cursor according to the determined jump parameter, and jumps from the current menu option to the target menu option according to the determined moving direction.

Take the disc-shaped menu as an example for illustration. The radius of the arc formed by the user rotating the positioning device for one circle can be obtained in advance. According to the radius and the number of menu items in the disc-shaped menu, the corresponding value for jumping to a menu item can be calculated. Straight-line distance, that is, the straight-line distance between the starting point and the end point of the positioning device when jumping to a menu item, then different straight-line distances correspond to different jump parameters, that is, the number of jump menu items, and the straight-line distance is proportional to the jump parameters. If the radius of the arc formed by the user turning the positioning device for one circle is R, and the number of menu items in the disc menu is N, then the calculation formula for the straight-line distance L corresponding to jumping to a menu item is: L=2Rsin( 360°/2N), the rotation distance L corresponding to different jump parameters can be calculated according to this formula, and stored in the memory of the terminal. Different rotation distances L correspond to different jump parameters. When determining the moving line of the positioning device After the distance, obtain the jump parameters of the current positioning device according to the mapping relationship between the pre-stored linear distance and the jump parameters, and control the menu selection cursor according to the determined jump parameters, and jump from the current menu option to the target menu according to the determined moving direction option. When setting the mapping relationship between the straight-line distance and the jump parameter, the range of the straight-line distance that can be set corresponds to the jump parameter.

In this embodiment, the mapping relationship between the linear distance moved by the positioning device and the ideal moving direction can be preset, and the corresponding ideal rotation direction can be determined according to the linear distance moved by the positioning device in the detected spatial movement event. The starting point coordinate information and the end point coordinate information, after determining the linear distance and moving direction of the positioning device, determine the ideal moving direction of the positioning device according to the mapping relationship between the linear distance and the ideal moving direction, and determine the moving direction of the positioning device and the ideal The included angle between the moving directions, if the determined included angle is greater than or equal to the second preset threshold value, no response will be made; if the determined included angle is smaller than the second preset threshold value, according to the preset linear distance and the jump parameter The mapping relationship determines the jump parameter corresponding to the detected spatial movement event; controls the menu selection cursor according to the determined jump parameter, and jumps from the current menu option to the target menu option according to the determined moving direction.

In the first embodiment of the menu control device based on space positioning equipment of the present invention, the control module 20 is further configured to, if the determined straight-line distance is greater than or equal to the first preset threshold value, Mapping relationship, determine the jump parameter corresponding to the detected spatial movement event.

In the movement event of the positioning device, the threshold value of the linear distance moved by the positioning device can be preset, and when the linear distance moved by the positioning device is greater than or equal to the preset threshold value, the user's movement event will be responded to. When a movement event of the positioning device is detected, sometimes the user just moves the positioning device without controlling the menu by moving the positioning device. If the straight-line distance is small, then the detected spatial movement event is considered invalid and the movement event of the positioning device is not responded to, so as to ensure the accuracy of menu control.

In the first embodiment of the menu control device based on the spatial positioning device of the present invention, the determining module 10 is also used to determine the distance between the moving direction of the positioning device and the preset ideal moving direction of the positioning device. Angle; the control module 20 is also used to control the menu selection cursor according to the preset jump parameters if the determined included angle is less than or equal to the second preset threshold, and jump from the current menu option to the target according to the determined moving direction menu options.

When the user moves the positioning device, there may be a deviation in the moving direction, or the user only places the positioning device or other operations without moving the positioning device to control the menu, then it is necessary to compare the moving direction of the positioning device with the preset ideal The angle between the directions, the preset ideal direction is the ray direction formed by the current menu option and the center point of the target menu option after jumping according to the preset jump parameters, and the direction between the first ray and the second ray is determined. The angle between them is the deviation when the user moves the positioning device. If the angle is less than or equal to the second preset threshold value, the menu selection cursor is controlled according to the preset jump parameters, and the current menu option jumps according to the determined moving direction. For the target menu option, the second preset threshold is preferably 45°. In this embodiment, other ray directions parallel to the first ray are the first ray directions, and the same is true for the second ray directions.

For example, in a long bar menu, if the user moves the positioning device to control the menu selection cursor to move up or down, the angle between the actual moving direction of the positioning device and the vertical direction of the long bar menu is greater than the second preset angle due to misoperation. If the threshold is set, it will not respond to this operation to ensure the accuracy of menu control. Or in the disc-shaped menu, when the user rotates the positioning device clockwise or counterclockwise, there may also be a problem of rotation deviation. In the center of the current menu option and the target menu option after jumping according to the preset jump parameters If the angle between the second ray direction formed by the point and the first ray direction formed by the starting point coordinate information and end point coordinate information of the positioning device is greater than or equal to the second preset threshold value, the operation will not be responded to ensure the accuracy of menu control sex.
