A Non-contact Interaction Method for 3D Display Devices

We propose a new interaction method to deal with the defects of traditional hardware in 3D interaction. The proposed method accurately captures human motion using the depth camera, obtains the RGB and depth images of the human body, and calculates the corresponding joints' 2D and 3D point coordinates. It estimates the human head orientation posture combined with the PnP function in OpenCV to control the presentation change of the scene in the three-dimensional display device. The method proposed in this paper is non-contact, does not need specific 3D glasses, and solves the problem that a monocular camera cannot be positioned. The experimental results show the precise control of the method proposed in this paper.
