User interfaces for ubiquitous computing

Abstract

The user interface is the component which acts on-behalf the system; it should then benefits from great design attention. In this paper I introduce the principle classes of ubiquitous user interfaces, with an emphasis on input devices. In the second section, I present a number of current research challenges followed by the design approach orientations. Examples of ubiquitous product interfaces and research projects are then given in details. I summarize afterward, some obtained results and encountered limitations in the presented examples. At last, I illustrate scenarios from ubicomp world and give my own one which I think realizable.
