Going Beyond the Desktop Computer with an Attitude

This dissertation is based upon the work within a number of research projects, five of which are presented in detail. The work follows the direction of research laid out by the Ubiquitous Computing and Augmented Reality research programs and concerns the broad question of where to go as we seek to take digital technology, and human interactions with this technology, beyond the traditional desktop computer. The work presented takes a design-oriented approach to Human Computer Interaction research. Five prototype systems are presented: Ambient displays for remote awareness, a navigation device providing guidance through tactile cues, a personal device for wastewater plant operators, paper cards enabling control of video playback, and a cell phone that enables you to ‘talk silent’. It is discussed how these prototypes, despite obvious differences, all reflect the same overall attitude towards the role of digital technology. It is an attitude emphasizing that integration of digital technology with everyday human activities means making computational power manifest as part of a larger patchwork of resources. Furthermore, it is an attitude promoting the design of digital technology that leaves the control and initiative with people and their earned ability to take appropriate action when faced with the particularities of the social and physical settings encountered in everyday life beyond the computer screen. In other words, this dissertation brings forward, by using five prototypes as examples, an attitude that encourages us to recognize, embrace, and take advantage of, the fact that human interaction with digital technology takes place, not in a vacuum, but in a rich and diverse world full of many resources for human action other than the digital technology we bring about.
