Tv interaction beyond the button press: Exploring the implications of gesture, pressure and breath as interaction mechanisms for a TV user interface

Abstract

In order to enhance users’ interactions with TV user interfaces we developed a prototypical multimodal interaction mechanism that combines tilting, pressing and puffing as input modalities for a novel interface. The interaction mechanism has been evaluated in an exploratory user experience and usability study that used a within subjects design investigating tilt as input mechanism to navigate through the 3D interface compared to tilt combined with pressure and breath input. Results of this first exploratory study indicate that while this uncommon and unfamiliar way to interact with a novel TV user interface impacts usability scores which were below average compared to traditional remote controls, the user interface approach in combination with the new interaction modalities resulted in above-average scores for the user experience dimension of hedonic quality. The findings are subsequently reflected and implications of using alternative input modalities for TV user interfaces are discussed.
