Description

  The present invention relates to a touch panel GUI device that selects an icon displayed on a display using a touch panel.

  2. Description of the Related Art In recent years, a user interface that performs content operation using a touch panel on an in-vehicle information terminal or the like has been adopted. Since the content can be selected simply by touching the display with a finger, the touch panel is expected as an intuitive user interface. In the conventional touch panel GUI device, when selecting a plurality of contents, the icons indicating the contents displayed on the display are selected by directly touching each one with a finger. Further, even if a plurality of contents can be selected, they can be selected only in a determined area unit (see, for example, Patent Document 1). FIG. 2 shows a conventional touch panel GUI device described in Patent Document 1. In FIG.

  In FIG. 2, in the input device for inputting data, the contact means 201 having a plurality of contact areas in a matrix form and a first for detecting an input when the contact areas receive a pressure within a predetermined range. Input mechanism means 202, a touch panel display 204 comprising a second input mechanism means 203 for detecting an input when the contact means receives a pressure greater than the predetermined range, and input data for selection on the touch panel. Is displayed in a display area drawn on the screen of the display device, and the display corresponding to the input contact area when the first input mechanism means 202 detects the input of the contact area. When the input of the contact area is detected by the feature display means 206 for displaying the area characteristic and the second input mechanism means 203, the input is performed. It was and an input data determination unit 207 for determining the input data on the screen corresponding to the contact area.

Further, as a conventional method for selecting a plurality of contents, although not using a touch panel, there has been a method in which a plurality of contents can be selected at the same time by specifying a selection range by drag and drop, such as an icon selection method in Windows.
Japanese Patent Laid-Open No. 5-189110 (page 1-8, FIG. 2)

  However, in the conventional configuration, one or more contents can be selected at the same time. However, since it can only be selected in a fixed area unit, if you want to select a desired amount of contents at the same time, eventually There has been a problem that the user must select and operate one by one, which is a heavy burden on the user.

  Further, in the method of determining the selection range by drag and drop as in Windows, for example, in the case of an in-vehicle terminal, the user must determine the selection range while looking at the operation. There was a problem that there was a problem in safety due to the increased burden.

  The present invention solves the conventional problem, and the user can intuitively control the selection area by pressing and holding a point on the display on which an icon indicating the content to be selected is displayed. An object of the present invention is to provide a touch panel GUI device capable of performing content selection.

  In order to solve the above-described conventional problems, the touch panel GUI device according to the present invention includes an icon display unit that displays one or more icons indicating content information on a display, and a screen coordinate value by touching the display using the touch panel. Coordinate input means for inputting, selection area creating means for creating a selection area based on the screen coordinate value inputted according to the time when the same screen coordinates are inputted, and the icon exists in the selection area It has an icon search means for searching whether or not, and an icon selection means for selecting all the icons existing in the selection area, thereby enabling intuitive mass content selection.

  According to the touch panel GUI device of the present invention, the size and shape of the selection region are controlled by the time that the point on the touch panel on which the icon indicating the content information to be selected is displayed is continuously pressed with the finger and the point of the same coordinate is continuously pressed. As a result, a large amount of content can be selected intuitively and with a simple operation.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a configuration diagram of a touch panel GUI device according to Embodiment 1 of the present invention. In FIG. 1, the same components as those in FIG.

  In FIG. 1, an icon display unit 101 displays one or more icons indicating content information on a display. The coordinate input means 102 inputs a screen coordinate value by touching the touch panel display 204. The selection area creation means 103 creates a selection area based on the screen coordinate value input according to the time when the same screen coordinates are input. The icon search means 105 searches whether the icon exists in the selection area. The icon selection means 106 selects all icons existing in the selection area.

  The operation of the touch panel GUI device configured as described above will be described in detail. This embodiment will be described as a touch panel GUI device in an in-vehicle information terminal.

  The icon display unit 101 displays one or more icons indicating content information on the touch panel display 204. Content information includes image data, video data, music data, and character data. The icon is an image representing content information linked one-to-one with the content information, and has display position information. The display position information can be defined in the screen coordinate system of the touch panel display, and the origin of the screen coordinate system can be set to any point on the screen. For example, in FIG. 3, the origin is set at the upper left of the display. The screen coordinates can be expressed in the form of two-dimensional coordinates (X, Y). Here, X represents the pixel difference in the display horizontal direction from the origin, and Y represents the pixel difference in the display vertical direction from the origin. Assuming that the upper left corner of the display is the origin coordinate (0, 0), the coordinates of a point 301 on the display that is X0 from the upper left corner of the display to the right and Y0 from the upper left corner of the display are denoted by (X0, Y0). The icon display may be two-dimensional or three-dimensional. The icon display unit 101 transfers information about the displayed icon to the icon search unit 104.

  The coordinate input means 102 inputs screen coordinates when the driver touches the touch panel display 204. The coordinate system input by the coordinate input unit 102 needs to have the same or some relationship with the coordinate system of the icon display unit 101. Further, when the driver touches the display with a plurality of fingers or the like, a plurality of screen coordinates are input. The coordinate input unit 102 transfers the screen coordinates to the selection area creation unit 103.

  The selection area creation unit 103 determines whether or not the screen coordinates are input by the coordinate input unit 102, and creates a selection area based on the screen coordinates while the same coordinates are input. Here, the selection area is formed from a plurality of pixels on the touch panel display, and the area of the selection area is equivalent to the number of pixels. Attributes such as the shape and area of the selection area to be created are determined by the time during which the same screen coordinates are input. The shape of the selection area is an arbitrary figure such as a rectangle or a circle, and may change from a rectangle to a circle with time. Further, the area of the selected region may be increased or decreased in proportion to time, the acceleration may be increased or decreased, and may be increased or decreased in stages. Moreover, you may have the upper limit and lower limit of the area of a selection area. That is, when the area D (T0) corresponding to the time T0 exceeds the upper limit value Dmax, D (T0) = Dmax, and when the area D (T0) falls below the lower limit value Dmin, D (T0) = Dmin. A selection area is created. For example, when the selection area creation means 103 creates a rectangular area whose area increases in proportion to time, input is performed when the screen coordinates 401 (X0, Y0) are inputted during the time T0 as shown in FIG. A square area of vertical and horizontal T0 × Length (Length is an increase amount) with reference to the screen coordinates 401 (X0, Y0) is created as a selection area. This square area has four points 402 (X0-T0 × Length / 2, Y0-T0 × Length / 2), 403 (X0 + T0 × Length / 2, Y0-T0 × Length / 2), 404 (X0 + T0 × Length / 2). , Y0 + T0 × Length / 2), 405 (X0−T0 × Length / 2, Y0 + T0 × Length / 2). Of course, instead of a rectangular area, a circular area having a diameter T0 × Length may be created as the selection area. While the input of the same coordinates from the coordinate input means 102 continues, the area or shape of the selected region changes with time. If there is no input from the coordinate input means 102, the selection area creation means 103 interrupts the area or shape change of the selection area, and performs the icon search means 104 using the selection area at that time. Here, instead of interrupting the change in the area or shape of the selected region, the icon search means 104 may be performed after the change in the area or shape of the selected region is moderately attenuated. In this way, the driver can automatically adjust the selection region and select a plurality of contents at the same time by simply pressing one point. Hereinafter, the operation of the selection area creating unit 103 will be specifically described. For example, FIG. 5 shows a music content playback system that maps an icon indicating music data about two emotion components to a two-dimensional coordinate space, and the selection area creation means 103 increases in area to a rectangular shape in proportion to time. Shall. In FIG. 5, the origin is set to a point 501 where two axes of emotion components intersect. In addition, icons indicating music contents are indicated by circles. Since the emotional components are centered on emotional components such as “bright / dark” and “violent / quiet”, songs having similar tempos and tunes, and songs of the same artist are easily mapped to positions close to each other. When the user wants to select “bright and intense music”, if the coordinates near the point 502 are input for a time T0, the selection area creating means 103 generates a rectangular area 503 having an area D (T0). If input is performed during time T1 (T0 <T1), a rectangular area 504 having an area D (T1) larger than that at time T0 is generated. It is possible to select a plurality of contents close to the “brightness” degree and “intensity” degree desired by the user at a time, and further, by controlling the time T input by the user, the area of the selected region can be determined. The selection area creation unit 103 transfers information about the created selection area to the icon search unit 104.

  The icon search unit 104 searches whether each icon displayed on the icon display unit 101 exists within the selected area. It is determined whether or not the center coordinates (Xa, Ya) of the icon on the touch panel are pixels within the selected area. At this time, instead of the center coordinates of the icon, an algorithm may be used to determine whether or not a part or all of the displayed icon is included in the selected region and determine whether or not it exists. Similarly, when there are a plurality of selection areas, the determination is made for each icon and selection area. It is determined whether all the icons displayed on the icon display unit 101 are included in the selection area, and the icon information included in the selection area is transferred to the icon selection unit 105.

  The icon selection means 105 puts the icon determined by the icon search means 104 into the selected area into the selected state. One or more icons in the selected state can be subjected to the same processing at a time, and content information associated with the icon can be processed at one time, such as moving, erasing, copying, and continuous playback. .

  The touch panel GUI device described so far is an invention in an in-vehicle information terminal, but is not limited to in-vehicle.

  The touch panel GUI device according to the present invention has a mechanism for controlling a selection area by continuously pressing one point on a display on which an icon indicating a content to be selected is displayed. It can be carried out. Therefore, the present invention can be applied to an entertainment GUI device having a touch panel such as an in-vehicle information terminal in which safety is regarded as important.
