Touch screen mobile user interface for seniors

This thesis focuses on the problem of designing a user interface for touch screen mobile phones optimized for elderly people. Typical modern smartphone has a large display, but its user interface is fairly complicated. We have performed a qualitative research between old people. Several hypotheses were expressed and verified by a quantitative research. We have identified the specific capabilities and limitations of old people, as well as summarized the recommended accessibility guidelines. We have designed a working prototype, tested several variants of the layout with elderly and discussed specific usability problems. Finally we did an empiric evaluation of the prototype and compared it with the standard Android interface. Technology behind the prototype was also discussed, how to efficiently use a game framework for creating and app and how to achieve the low battery consumption.
