RATA: Codeless Generation of Gesture Recognizers

Abstract

Touch and stylus sensitive computer displays are widely available. Yet, the development of gesture sets to support these interaction methods continues to be difficult. We present RATA, a tool for interaction designers and software developers to create gesture recognizers for novel and custom gesture sets. Guided by the RATA wizard, the developer: defines their gesture set; collects example gestures; labels them with the support of an auto labeller; and generates the recognizer model file – no coding or expert knowledge of recognizers is required. Incorporating the recognizer into a program requires just two lines of code. Our evaluations show high user satisfaction and that novice software developers can design a customized gesture set and generate a recognizer in about 20 minutes.
