AI Technical Summary
Existing VR glasses or VR headsets cannot detect the spatial displacement of the user's head and other body parts along the X, Y, and Z axes of the spatial coordinate system, resulting in poor full-body engagement and the inability to avoid obstacles in real time.
It employs a main control unit, motion detection unit, and degree-of-freedom detection unit. It detects joint movements through electromyography electrodes and skin tension strain gauges, and tracks body translation and rotational degrees of freedom using an ultrasonic transceiver module, achieving full-body six-degree-of-freedom tracking. It also displays obstacles through a virtual construction unit and is equipped with a safety alarm function.
It achieves full-body six-degrees-of-freedom tracking of the user, captures dynamic object changes in real time, provides obstacle avoidance function, and enhances the experience of virtual reality display technology. It is especially suitable for virtual scenarios that require full-body participation, such as football games and fighting games.
