Freehand Gestural Selection Design for Interactive Television

Televisions are delivering more interactive experiences with internet connections, various applications and interactive content. However, traditional TV remote controls are not well suited to such interactive TV platforms. With the widespread use of freehand gestural interaction enabled by low-cost cameras, gestural interfaces are a promising solution for controlling interactive TV. Currently, freehand gestural interaction is still challenging and often does not lend itself to established interaction techniques that have been developed for traditional graphical user interfaces. In this paper we propose a design method for freehand gestural selection, which combines a Reach technique, expanding target and 3D freehand gesture, and we provide some brief examples of this design method.
