Tiivistelmä
Functionalities and content available to consumers via TV and media centers have been rapidly expanding during the previous decade. To cover all the available functionalities without ending up with a remote control with hundreds of buttons, multimodal user interfaces may be employed. As computing power and available sensors increase in common smartphones it is tempting to implement multimodal user interfaces to control the media centers. Enabled by accelerometer sensors on smartphones, motion gesture interfaces may be utilized in multimodal interaction.
Multimodal Media Center was implemented at the University of Tampere to study multimodal interaction in this context. A gesture interface was designed as part of the multimodal user interface for the Multimodal Media Center, and after disappointing user experience results from evaluations it was redesigned. The first version of the gesture interface utilized continuous gestures and attempted to offer full control over the Multimodal Media Center by gesture interactions while the second, mode-based version of the gesture interface aimed to enhance interaction via keypad instead of fully replacing it. The second version was evaluated with improved results.
The continuous gesture interface and the mode-based gesture interface were evaluated in four experiments. The experiments are reported in four articles which form the base of this thesis. The gesture interfaces were developed in an iterative process with the evaluation results, user comments, and observations being considered.
The focus of this thesis is on gesture interaction as a part of the multimodal user interface, and a comparison between the two styles of interaction implemented in the two versions of the gesture interface. Included in discussed topics are the evaluation results of the gesture interfaces, their multimodal feedback, and an examination of the strong and weak qualities of both. The thesis is concluded with discussion on applying the findings on modern platforms, combining the best of both gesture interaction styles.
