Parsimony & Transparency in Ubiquitous Interface Design

by Carson Reynolds

A poster and extended abstract detailing a collaboration I did on perceptual interfaces was accepted at the Ubiquitous Computing International Conference (aka UbiComp). The paper details our application of parsimony and transparency as design principles to the development of a tangible user interface for ubiquitous interaction. The jargon-less version of the last sentence would be: we programmed a vision system that observed people using a go board, and provided some augmentations using an LCD projector . An experiment conducted found that people could perform tasks twice ask quickly using our augmented system compared to a GUI counterpart, and that they preferred it in comparison.
