Improving Interaction with TV- Based Applications through Adaptive Multimodal Fission

In this chapter, the authors describe the design and implementation of an adaptive multimodal fission component integrated in the multimodal GUIDE framework. This component is able to adapt any HTMLbased application’s UI to a specific user’s characteristics, making it possible for elderly and impaired users to interact by offering several output modalities that try to overcome possible interaction difficulties. They also present an evaluation of the proposed solution, conducted with more than 50 participants, that shows the efficiency of multimodal adaptation in increasing task perception and task execution.
