Tool demo: Operating diagram editors through unistroke gestures

摘要

In software development processes, diagram editors play an important role. For instance, editors for creating UML diagrams are often used in early stages of software development. Three input methodologies can be distinguished: traditional mode-based editing, sketch-based editing, and gesture-based editing. Most of today's diagram editors are mode-based and use the mouse as an input device. (Multi-)touch inputs have not been integrated very well, although a variety of touch input devices, such as (multi-)touch monitors and tablet computers, are quite common today. In this paper, we provide some insights into the integration of an off-the-shelf unistroke gesture recognizer into an existing diagram editor framework, and give some details about three example diagram editors that incorporate a new interaction mode, the so-called gesture mode.
