Problems solved by technology
[0002] At present, most of the positioning equipment for three-dimensional interactive scenes such as virtual reality and mixed reality are mainly based on infrared positioning and infrared somatosensory camera positioning. Some adopt ultrasonic three-dimensional positioning technology, but the receiving end of the ultrasonic signal is large and fixed, and the omnidirectional ultrasonic transmitting device used mostly uses a two-dimensional omnidirectional ultrasonic transmitter, but there is no three-dimensional omnidirectional ultrasonic transmitter, and has not been updated. Good realization of three-dimensional omnidirectional ultrasonic emission, most of them have positioning dead angle, the positioning is not accurate enough, it is not conducive to carrying and wearing, and the human-computer interaction function is not strong
