Research on visual attention distribution model of 3D gesture in the gesture interface

Aiming at the problem of low speed in 3D freehand gesture tracking in gesture-oriented 3D human-computer interactive interface, we introduce the visual attention mechanism into the human-computer interaction interface and propose hand gesture tracking algorithm based on distribution of visual attention model. First of all, the change process of the eye sight is accurately tracked using eye tracker. Then, we carry on careful data analysis and establish visual attention model for different events. Finally, we design a 3D gesture tracking algorithm based on visual attention model. The major contribution is that we establish the visual attention model for the 3D hand model and achieve a fast 3D hand tracking algorithm based on the visual attention model. Experimental results show that the proposed algorithm effectively improves the interaction speed.
