Separating Gesture Detection and Application Control Concerns with a Multimodal Architecture

Gesture-controlled applications typically are tied to specific gestures, and also tied to specific recognition methods and specific gesture-detection devices. We propose a concern-separation architecture, which mediates the following concerns: gesture acquisition, gesture recognition, and gestural control. It enables application developers to respond to gesture-independent commands, recognized using plug-in gesture-recognition modules that process gesture data via both device-dependent and device-independent data formats and callbacks. Its feasibility is demonstrated with a sample implementation.
