Mouthbrush: drawing and painting by hand and mouth
We present a novel multimodal interface which permits users to draw or paint using coordinated gestures of hand and mouth. A headworn camera captures an image of the mouth and the mouth cavity region is extracted by Fisher discriminant analysis of the pixel colour information. A normalized area parameter is read by a drawing or painting program to allow read-time gestural control of pen/brush parameters by mouth gesture while sketching with a digital pen/tablet. A new performance task, the Radius Control Task, is proposed as a means of systematic evaluation of performance of the interface. Data from preliminary experiments show that with some practice users can achieve single pixel radius control with ease. A trial of the system by a professional artist shows that it is ready for use as a novel tool for creative artistic expression.
