Abstract Preferred Interaction, Don’t Leave Home without It!

In this paper we restructure the idea of ubiquity, seamless and seamful design into a single collaborative framework. We briefly explore the notions of seamlessness, seamfulness and invisibility in connection to the design of ubiquitous system. Additionally, we also briefly explore the connection of the activity theory to the above notions when we deal with user interaction. This leads to the taxonomy for evaluation of the ubiquitous computing system. One of the purposes of the taxonomy is to clarify the map of notions invisibility, seamless, and seamful. Additionally, the taxonomy shows that one alternative support to the seamfulness is to have the ubiquity in the interaction modal so the user have a degree of independent to have their preferred interaction. This idea is the motivation of the development of the ubiquitous tabletop augmented reality interaction kit in institute FAW. The experimentation on the idea implementation is illustrated. 1
