xstroke: Full-screen Gesture Recognition for X

Gesture recognition is a common method of text input on handheld and other pen-based computing devices. Xstroke is a full-screen gesture recognition program for the X Window System. The touchscreen of a typical pen-based device is divided into two regions, a primary region for application display and interaction, and a secondary region for gesture input. Full-screen gesture recognition improves on the typical implementation by sharing the entire screen for both purposes. Applications benefit as more screen real estate is available. Recognition performance improves due to increased information from larger gestures. Usability increases as less time is lost switching attention between two separate screen regions. Full-screen gesture recognition presents several userinterface design challenges. Conventional GUI interaction is pointer driven. This makes it difficult for systems with single-button pointer devices to distinguish between GUI interaction and character input. Several solution...
