As people want to use computers and mechanical systems with a minimal effort of learning new input devices become more important. A very ergonomic and intuitive user interface can be realized through gesture recognition. In many fields gesture recognition is used, for example for robot programming and controlling, for the handling of complex simulation and medical data or to help functionally handicapped people. In our approach we use static hand gestures in combination with dynamic movements of arm and hand for the generating and handling of sketches and simple geometries. Our main goal is to develop an intuitive VR-based computer aided design system that allows a designer a intuitive modelling during all phases of construction. This means we look at the design process from the early phases of sketching up to the generation of a more exact CAD-model.     «
