Problems solved by technology

[0004] 1. The equipment is bulky. The VR treadmill needs a boom structure to stabilize the user's posture. It also needs to cooperate with the concave spherical structure under the feet. The overall equipment is huge and needs to occupy the size of a room.
[0005] 2. The installation of equipment is complicated. The VR treadmill is composed of several huge parts. The installation process is cumbersome and requires professional installation.
[0006] 3. The use experience is very poor. This kind of equipment needs to wear sensors on the feet to sense the movement state, and also needs to cooperate with special shoes like roller skates
It requires a tedious wearing process in the early stage, and a lot of practice is also required during use, and it is necessary to complete running, turning and other actions during use, which consumes physical strength for a long time

Description

Technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a virtual pan-tilt device and an intelligent behavior perception method. Background technique [0002] At present, most VR roaming devices are of the type of VR treadmill. When using, it is necessary to wear a pair of sensor devices similar to skates on the feet, and it is also necessary to configure a concave spherical structure to match the feet. When the user is roaming, the feet must slide toward the inner surface of the concave spherical surface, so as to achieve the effect of roaming running, and a lot of exercises are required during the roaming process, which consumes physical strength and leads to extremely poor experience. [0003] Most existing VR roaming devices have the following disadvantages: [0004] 1. The equipment is huge. The VR treadmill needs a boom structure to stabilize the user's posture. It also needs to match the concave spherical structure unde...
