Summary

Recommendation ITU-T H.704 defines the general requirements, functional elements and interfaces supporting enhanced capability of user interaction by gesture recognition and controlling over Internet protocol TV (IPTV) terminal devices, based on the enhanced user interface (UI) framework defined in Recommendation ITU-T H.703. Those functional elements are described in the gesture controlling enabler and gesture recognition enabler defined in this Recommendation. Moreover, the procedures of interaction between the gesture recognition device and the gesture-controlled device are defined with the recommended information used in the interaction.

This Recommendation enables the gesture controlling feature in the enhanced IPTV user interface defined in Recommendation ITU-T H.703. With those features, users can control the operation of IPTV applications in an IPTV terminal device in a convenient, natural and comfortable way.
