Adjustable interactive rings for iDTV

Literature has shown that the remote control, the main artifact for interaction with the television system, is not adequate to mediate the interaction with Interactive Digital Television (iDTV). This work presents and discusses a new proposal of artifact for interaction with iDTV applications. The paper presents in details the product design and the interaction language for the new digital artifact which presupposes its use by everyone, in the widest possible extension. Additionally, we show the prototype of these new hardware devices and an evaluation with prospective end users of the solution described in this paper.
