Research on motion sensing interaction technology based on HTC Vive

The motion sensing interactive devices can greatly enhance the sense of immersion. In this paper, the flow of the interaction with the HTC Vive is sums up five step. Analyzes the positioning principle of the HTC Lighthouse and introduce the function of the HTC thumbstick. Then defines the quaternion, and obtains the quaternion of changed state from HTC helmet and thumbstick in the real world. Calculates the visual angle and the picked model rotation in the virtual world according to the quaternion in the real world. Moreover designs multi person cooperative interaction model based on object model. Finally an interaction simulation system adopting HTC Vive device was achieved. The result shows the calculation method is correct.
