We describe a pointing and speech alternative to the current paint programs based on traditional devices like mouse, pen or keyboard. We used a simple magnetic field tracker-based pointing system as input device for a painting system to provide a convenient means for the user to specify paint locations on any virtual paper. The virtual paper itself is determined by the operator as a limited plane surface in the three dimensional space. Drawing occurs with natural human pointing by using the hand to define a line in space, and considering its possible intersection point with this plane. The recognition of pointing gestures occurs by means of a partial recurrent artificial neural network. Gestures along with several vocal commands are utilized to act on the current painting in conformity with a predefined grammar
