Real-time vision pointer interface

This paper presents a new solution for human-computer interaction that utilizes hand gestures for intuitive operation without any devices restraining the hand freedom. The proposed system is able to completely replace a mouse as a pointing device. Moreover, it extends mouse capabilities by a set of hand gestures. The system is a vision-based interface, and a simple webcam is sufficient for proper operation. The article reveals concepts and algorithms used for construction of the system, which provide fast calculations and high performance using typical hardware.
