Abstract
Described is an approach to gesture interaction that is based on user interface widgets. In order to detect user gestures, the widgets are provided with hotspots that are monitored using a camera for predetermined patterns of occlusion. A hotspot is a region where a user interacts with the widget by making a gesture over it. The user's gesture may be detected without the user physically touching the surface displaying the widget. The aforesaid hotspots are designed to be visually salient and suggestive of the type of gestures that can be received from the user. Described techniques are advantageous in relation to conventional systems, such as systems utilizing finger tracking, in that they can better support complex tasks with repeated user actions. In addition, they provide better perceived affordance than conventional systems that attempt to use widgets that are not designed for gesture input, or in-the-air gesture detection techniques that lack any visual cues.
