Abstract

The invention discloses a virtual space moving control method and device based on an inertia sensor. The method applicable to head-mounted VR equipment includes: when a user wears the head-mounted VR equipment and moves at one spot in a limited space, and the vertical acceleration of the user is continuously acquired through the inertia sensor in the head-mounted VR equipment; acquiring a corresponding acceleration curve in continuous time according to the continuously acquired vertical acceleration, and acquiring the frequency of maximum acceleration according to interval time corresponding to each peak and / or valley in the curve; converting into the speed of the horizontal moving of the user in a virtual space according to the frequency of the maximum acceleration; mapping the speed of the horizontal moving into the virtual space to allow the user in the virtual space to move at the speed. By the virtual space moving control method, virtual space moving control when the space is limited or an external device is unavailable is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an inertial sensor-based virtual space movement control method and device. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment, which is an interactive three-dimensional dynamic scene and a system simulation of entity behavior that integrates multi-source information, allowing users to immerse themselves in the virtual world. Environment. [0003] Virtual reality technology (VR) mainly includes aspects such as simulated environment, perception, natural skills and sensing equipment. The simulated environment is a real-time dynamic three-dimensional realistic image generated by a computer. Perception means that ideal VR should have the perception that all human beings have. In addition to the visual perception generated by com...
