Even after more than two decades of input devices development, many people still find theinteraction with computers an uncomfortable experience. Efforts should be made to adapt computers to ournatural means of communication: speech and body language. The aim of this paper is the proposal of a realtime command system through hand gesture recognition, using general-purpose hardware and low costsensors, like a simple personal computer and an USB web cam, so any user could make use of it in hisindustry or home. The basis of our approach is a fast segmentation process to obtain the hand gesture fromthe whole image, which is able to deal with a large number of hand shapes against different backgroundsand lighting conditions, and a recognition process that identifies the hand posture for different controlapplications.
