The invention provides a wireless transmission space positioning pen based on virtual coordinates, and relates to the technical field of virtual reality man-machine interaction; and the wireless transmission space positioning pen comprises a voice input module, an operation panel, a light-emitting marking point, a direction sensor, a magnetic sensor, a wireless transmission module, a data collection module and a data processing module. According to the invention, two input channels and interaction modes of touch control and voice can be supported and naturally switched, and the two input channels and interaction modes can be matched for interaction; more accurate target positioning can be carried out, and the efficiency of target positioning related tasks on the touch equipment is improved; in the interaction process, the positioning real-time performance is high, the precision is high, the stability is high, and the problem that operation is inaccurate due to natural shaking of the hand and positioning errors of a space positioning pen in a pen posture interaction mode is solved.
Description
technical field [0001] The invention relates to the technical field of virtual reality human-computer interaction, in particular to a wireless transmission space positioning pen based on virtual coordinates. Background technique [0002] With the development of computer graphics, computer simulation technology, human-computer interface technology, multimedia technology and sensing technology, virtual technology, such as human-computer interaction in virtual reality and human-computer interaction in mixed reality, has become a research hotspot. The development of virtual technology has greatly promoted the development of interactive products and services such as stereoscopic projectors, stereoscopic remote controls, and 3D displays. [0003] How to make the way of human-computer interaction more natural and smooth has become the key link to realize these technologies. As a natural way of interaction, pen interaction has attracted more and more attention, and it is a research...
