[0062]

[0063] figure 1 It is a schematic flowchart of the data transmission method according to the first embodiment of the present disclosure. The data transmission method in this embodiment can be performed by, for example, a handle, and the handle can be a left handle or a right handle.

[0064] Such as figure 2 As shown, the handle can include an IMU sensor module, a user input module, a touch key input module, a wireless communication module, a light emitting diode module, a linear motor module and an antenna. The sensor data obtained by the handle, user input data, touch data, etc. are all sent to the head-mounted display device through the wireless communication module, and can receive broadcast signals from the head-mounted display device through the wireless communication module. It should be noted that, in this embodiment, the wireless communication module uses a 2.4G data communication protocol.

[0065] Specifically, such as figure 1 As shown, the data tra...

[0098] Image 6 A schematic flowchart of the data transmission method according to the second embodiment of the present disclosure. The data transmission method in this embodiment can be executed by, for example, a head-mounted display device, such as a VR helmet, VR glasses, and the like.

[0099] Specifically, such as Image 6 As shown, the data transmission method of this embodiment may include the following steps 6100 and 6200:

[0100] Step 6100, sending a broadcast signal at a preset period; the broadcast signal at least includes time synchronization information and / or control data.

[0101] Wherein, the time synchronization information is used to make the handle adjust its own time, so that the time of the handle is the same as the time of the head-mounted display device. The control data is, for example, controlling the light-emitting diode of the handle to light up, controlling the vibration of the motor, etc., so that the handle performs corresponding c...

Abstract

The embodiment of the invention discloses a data transmission method, device, equipment and system. The method comprises the following steps that: a broadcast signal from the head-mounted display device is received; the broadcast signal at least comprises time synchronization information and / or control data; the broadcast signal is sent according to a preset period; and handle data is sent to the head-mounted display device in a pre-obtained wireless transmission channel according to a preset time interval.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and more specifically, to a data transmission method, device, device, and system. Background technique [0002] The data transmission between the virtual reality (Virtual Reality, VR) head-mounted display device and the handle is based on wireless communication protocols, such as Bluetooth, BLE, ZigBee, WIFI, etc. [0003] In VR SLAM (simultaneous localization and mapping, real-time positioning and map construction) tracking, the wireless communication system is required to be able to realize the sensor data of the handle controller inertial measurement unit (Inertial Measurement Unit, IMU), the handle controller input unit such as joystick data, Transmission of trigger data, button data, touch button data, and battery power data. It is also required that the wireless communication system can realize the synchronous transmission of data between the head-mounted display device an...
