A touch perception algorithm based on depth information

The paper presents an algorithm of touch perception based on depth information. Firstly, the area of perception is determined according to the depth information, which corresponds to the two types of action: movement and click. Secondly, the two types of perception are defined based on the movement of hand, which provide the basic interactive datum. Thirdly, the relationship between the perception and display is built on the basis of mapping from depth to pixel, which is helpful to keep the position consistency between touch and feedback. The result shows that new algorithm is effective and accurate for touch perception in arbitrary flat area.
