Abstract

This chapter presents the development of a new human-machine interface - a wheelchair controlled by the recognition of human hands' static gestures. The application will allow the occupant of an intelligent wheelchair to communicate with certain objects in order to facilitate their daily life. The suggested methodology draws on the use of computational processes and low-cost hardware. The development of the application involved dealing with computer vision issues in a comprehensive way. It was based on the steps of video image capture, image segmentation, feature extraction, pattern recognition and classification. In terms of its relevance and impact, the application described in the chapter promotes a more natural and intuitive mode of interaction for disabled individuals, which is expected to improve their quality of life.
