1, VR head display: It is a head-mounted display device that closes people's vision and hearing to the outside world and guides users to feel in a virtual environment. Its display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eye will have a stereoscopic impression in its mind after obtaining these different information.

2.VR all-in-one machine: VR head display with independent processor (virtual reality head-mounted display device). With independent operation, input and output functions.

Technologies needed for vr games:

1, dynamic environment modeling technology

The establishment of virtual environment is the core content of VR system, and its purpose is to obtain the three-dimensional data of the actual environment and establish the corresponding virtual environment model according to the needs of application. ?

2. Real-time 3D graphics generation technology.

The generation technology of 3D graphics is mature, so the key is "real-time" generation. In order to ensure real-time, the refresh frequency of graphics should be at least 15 frames/second, and preferably higher than 30 frames/second. ?

3. Stereo display and sensor technology

The interactive ability of virtual reality depends on the development of stereoscopic display and sensor technology, and the existing equipment can not meet the needs. The research of mechanical and tactile sensing devices needs to be further deepened, and the tracking accuracy and tracking range of virtual reality equipment need to be improved. ?

4. Application system development tools

The key to the application of virtual reality is to find suitable occasions and objects. Choosing suitable application objects can greatly improve production efficiency, reduce labor intensity and improve product quality. In order to achieve this goal, we need to study the development tools of virtual reality. ?

5. System integration technology

Because VR system contains a lot of perceptual information and models, system integration technology plays a vital role, including information synchronization technology, model calibration technology, data conversion technology, data management model, identification and synthesis technology. ?
