implications for a gesture design tool
Interest in pen-based user interfaces is growing rapidly. One potentially useful feature of pen-based user interfaces is gestures, that is, a mark or stroke that causes a command to execute. Unfortunately, it is difficult to design gestures that are easy 1) for computers to recognize and 2) for humans to learn and remember. To investigate these problems, we built a prototype tool typical fo those used for designing gesture sets. An experiment was then performed to gain insight into the gesture design process and to evaluate this style of tool. The experiment confirmed that gesture design is very difficult and suggested several ways in which current tools can be improved. The most important improvement is to make the tools more active and provide more guidance for designers. This paper describes the gesture design tool, the experiment, and its results.
