User experience of speech controlled media center for physically disabled users

In this paper, we present results from a long-term user pilot study of speech controlled media center. The pilot users in this case were physically disabled and the system was installed in their apartment for six weeks. We designed a multimodal media center interface based on speech. Full speech control is provided with a hands-free speech recognition input method for people with physical disabilities. In addition, the application includes a zoomable context + focus GUI in tight combination with speech output. The resulting interface was designed following human-centered principles. Finally, the results of user experience studies are presented.
