The Bluetooth transmitter 130 is used to transmit Bluetooth signals, and can be installed on obstacles or when the Bluetooth transmitter 130 is arranged so that each obstacle is located within the detectable range of the Bluetooth signal. Wherein, when the virtual reality device positioning system 100 has a plurality of Bluetooth transmitters 130, each Bluetooth transmitter 130 has its corresponding serial number, so that when the host 110 receives a Bluetooth signal, it can The serial number of the Bluetooth transmitter 130 is accessed from the storage unit. The first virtual reality device 120 at least includes a first Bluetooth receiver, a first communication unit and a first display unit. The first Bluetooth receiver is used for receiving the Bluetooth signal output by the Bluetooth transmitter 130 .

The first display unit is used for receiving the display content, the position signal and the warning signal corresponding to the first virtual reality device 120 from the host terminal 110 . The first display unit is worn on the user's head, and can be a display panel (eg, a thin film liquid crystal display panel, an organic light emitting diode panel, or other devices with display capability, etc.).

According to an embodiment of the present invention, when the first virtual reality device 120 enters the range where the first Bluetooth receiver of the first virtual reality device 120 can receive the Bluetooth signal output by the Bluetooth transmitter 130, the first Bluetooth receiver of the first virtual reality device 120 A bluetooth signal with a signal strength is received, and the first virtual reality device 120 sends back the bluetooth signal and the corresponding signal strength received by the first bluetooth receiver to the host terminal 110 through the first communication unit. deal with. After receiving the bluetooth signal of the first virtual reality device 120 and the corresponding signal strength, the host terminal 110 determines the position of the first virtual reality device 120 according to the corresponding signal strength of the bluetooth signal and the corresponding serial number of the bluetooth transmitter 130, and The position of the first virtual reality device 120 is displayed through the first display unit of the first virtual reality device 120 .

In addition, when the distance (first distance) between the first virtual reality device 120 and the obstacle is less than a predetermined value, the host terminal 110 further outputs a warning signal to the first virtual reality device 120 to inform the user to pay attention to the obstacle. The warning signal can be implemented in various ways, such as displaying a warning window on the first display unit of the first virtual reality device 120 or displaying the current image in front of the user on the first display unit.

It is worth noting that the first virtual reality device 120 may further include a first processing unit, and the determination action performed by the host 110 may also be implemented by the first processing unit of the first virtual reality device 120 itself.

According to another embodiment of the present invention, when the user's activity range is large, the virtual reality device positioning system 100 may further include a WIFI wireless network composed of a plurality of wireless access points (APs), and the WIFI wireless network The position of the first virtual reality device 120 is calculated by, for example, triangulation, so as to reduce the installation cost of the virtual reality device positioning system 100 . The location information corresponding to the first virtual reality device 120 or other virtual reality devices obtained by the WIFI wireless network is all received through the transmission unit of the host computer 110 . In addition, since the accuracy of Bluetooth positioning is better than that of WIFI positioning, when the range of the WIFI wireless network overlaps with the signal range of the Bluetooth transmitter 130, the location of the first virtual reality device 120 is determined based on the corresponding Bluetooth signal. The position of the first virtual reality device 120 is mainly used to improve the positioning accuracy of the first virtual reality device 120 .

According to another embodiment of the present invention, the first virtual reality device 120 further includes a plurality of infrared transmitters and a plurality of infrared receivers, respectively corresponding to different directions of the first virtual reality device 120 .

For example, when the first virtual reality device 120 is located in the front right of the second virtual reality device (ie, the second virtual reality device is located in the left rear of the first virtual reality device 120 ), the host 110 enables the first virtual reality device 120 to be turned on The infrared transmitter located at the left rear causes the first virtual reality device 120 to increase its transmission power, so that the infrared receiver located at the right front of the second virtual reality device at the rear can receive the infrared signal faster, so as to accelerate the host side 110 determines the shortest distance between the two virtual reality devices.

In addition, when the host 110 receives the infrared signal from the second virtual reality device and calculates the shortest distance between the two virtual reality devices according to the infrared signal, the host 110 can further correct the positions of the two virtual reality devices according to the shortest distance coordinates, and the relative positional relationship of the two virtual reality devices is respectively transmitted to the display units of the two virtual reality devices. When the host 110 calculates that the distance between the two virtual reality devices is smaller than the predetermined value, the host 110 outputs warning information to the two virtual reality devices respectively, so as to display the warning window on the display unit of the virtual reality device or on the display unit Displays the current image in front of the user. Similarly, each calculation performed by the aforementioned host 110 can also be implemented by the processing unit of each virtual reality device, and then the data exchange is performed by the respective communication unit.

First, in step S201, the host 110 enables at least one Bluetooth transmitter 130 to output a Bluetooth signal and/or enables a WIFI wireless network. The Bluetooth transmitter 130 is disposed on the obstacles or each obstacle is located within the detectable range of the Bluetooth signal, and the detection range of the WIFI wireless network covers the activity range of the first virtual reality device 120 . In step S202, the first Bluetooth receiver of the first virtual reality device 120 receives the Bluetooth signal and the corresponding signal strength, or the host 110 detects the first virtual reality device 120 through the WIFI wireless network. In step S203 , the host 110 calculates the position of the first virtual reality device 120 according to the Bluetooth signal with signal strength or the WIFI wireless network output by the first communication unit of the first virtual reality device 120 . Wherein, when the virtual reality device positioning system 100 is provided with a WIFI wireless network, the host 110 calculates the position of the first virtual reality device 120 through triangulation through the WIFI wireless network. In step S204, the host 110 determines whether the second virtual reality device is detected. When the host terminal 110 detects the second virtual reality device, the process proceeds to step S205, and the host terminal 110 determines whether the distance between the two virtual reality devices is smaller than a predetermined value. When the distance between the two virtual reality devices is less than the predetermined value, the process proceeds to step S206, and the host terminal 110 outputs a warning signal or displays the image captured by the front lens on the display unit of each virtual reality device.

Conversely, when the host 110 detects only the first virtual reality device 120, or the distance between the two virtual devices is greater than or equal to the predetermined value, the process proceeds to step S207, and the host 110 determines the relationship between each virtual reality device and the obstacle. Whether the distance between objects is less than a predetermined value. When the distance between the first virtual reality device 120 or other virtual reality devices and the obstacle is less than the predetermined value, the process proceeds to step S206, and the host terminal 110 outputs a warning signal or displays the image captured by the front lens on the corresponding virtual reality device. on the display unit of the reality device. Conversely, when the distance between the first virtual reality device 120 and the second virtual reality device and the distance between the obstacles in the first virtual reality device 120 are both greater than or equal to the predetermined value, then go back to step S202, each The virtual reality device continuously receives the bluetooth signal, so that the host 110 can determine the position of each virtual reality device according to the strength of the bluetooth signal, or the host 110 can detect the position of each virtual reality device through the WIFI wireless network.
