Issues in Personalizing Shared Ubiquitous Devices.


As ubiquitous computing becomes widespread, we are increasingly coming into contact with “shared” computer-enhanced devices, such as cars, televisions, and photocopiers. Our interest is in identifying general issues in personalizing such shared everyday devices. Our approach is to compare alternative personalization methods by deploying and using alternative personalization interfaces (portable and embedded) for three shared devices in our workplace (a presentation PC, a plasma display for brainstorming, and a multi-function copier). This paper presents the comparative prototyping methodology we employed, the experimental system we deployed, observations and feedback from use, and resulting issues in designing personalized shared ubiquitous devices.
