Usability increases less time lost switching attention between separate regions. presents several userinterface design challenges. Conventional GUI interaction pointer driven. This makes it difficult systems with single-button devices distinguish character Several solutions this problem are examined. simple feature-based engine at heart has proven capable resolving sets 100 different gestures up 95% accuracy. freely available become predominant system X-based
