Mike Kuniavsky of ThingM wrote an article on ubiquitous computing user experience design for ACM’s interactions magazine.

The user experience design of most everyday ubiquitous computing devices—things you see in gadget blogs—is typically terrible. That’s because we do not address ubicomp user experience design as a distinct branch of interaction design, much as we did not treat interaction design as separate from visual design in the early days of the Web.

In the last couple of years, I have conducted research for and designed a number of ubicomp user experiences. In the process, I’ve seen some of the seams between industrial design, interaction design, architecture, and ubiquitous computing user experience design. In this article, I have tried to pull together some approaches that seem particularly valuable in the ubiquitous computing user experience world. None is unique to it: They’re all general design guidelines, but they seem to apply particularly well to the particular design challenges of this field.

The final article is only available to subscribers, but he published a preprint version of it on his blog.
