Abstract—The paper presents a vision-based natural barehand gesture recognition for remote operating LTSS, which offers simple, high resolution and robust against occlusion. The system is a kind of embedded systems that combines the hardware and software design. It allows users to interact with the information by pointing large screen directly with their fingertips approximately parallel to ground. The key technology of the system is fingertip recognition, tracking, computer vision algorithms and operation judgment. Experiments show that our approach extremely suit to be embedded into real-time human-computer interaction systems.

Index Terms—large touch screen; computer vision; human computer interaction; fingertip recognition; fingertip tracking; coordinates mapping; image differencing
