Vertoid: exploring the persuasive potential of location-aware mobile cues
It is widely accepted that ubiquitous computing (UbiComp) prototyping is one of the methods that can be used to anticipate how future systems are to be designed and what problems can be solved with computational devices. This paper discusses a number of small-scale projects in which researchers attempted to apply some of the UbiComp methodologies to finding solutions to fairly simple problems that surface during everyday campus life. The process aims at finding ways to discover how pervasive technology can affect even the most trivial aspects of human lives as well as trying to make more profound changes. The projects discussed in this paper include a tool for measuring and communicating campus room occupancy, a mobile mode-of-transport detector and a context-aware application for reducing domestic carbon footprint. The applications illustrate the vast possibilities that present mobile platforms offer to the UbiComp researcher and, most importantly, the opportunity to create large numbers of prototypes by numerous users that can be easily evaluated. The authors claim that the software fulfils many UbiComp prototyping requirements and gives great opportunities for field studies. Furthermore, the wide availability of prototyping techniques suggests that computer enthusiasts are now easily immersed in the experience of the UbiComp of the present and the future face of computing can be shaped by many. If, however, one is to verify the applicability of the prototyped systems, even more users must be involved in the UbiComp experience.
