Ubiquitous mobile computing devices offer the opportunity to provide easy access to a rich set of information sources. Placing the display for this computing device on the user’s wrist allows for quick, easy, and pervasive access to this information. In this paper we describe a user interface model and a set of five applications we have developed, with the aim of providing a user interface that supports lightweight interactions. Our goal is to make our pervasive watch as simple to use as a common wrist-watch worn today.
