EdgeWrite is a new unistroke text entry method for handheld devices designed to provide high accuracy and stability of motion for people with motor impairments. It is also effective for able-bodied people. An EdgeWrite user enters text by traversing the edges and diagonals of a square hole imposed over the usual text input area. Gesture recognition is… (More)
Designers often borrow from the natural world to achieve pleasing, unobtrusive designs. We have extended this practice by combining living plants with sensors and lights in an interactive display, and by creating a robotic analogue that mimics phototropic behavior. In this paper, we document our design process and report the results of a 2-week field study.… (More)
Modeled on how humans use eye contact to engage one another, the interaction technique presented here enables users to effectively engage devices in ubiquitous computing contexts. Equipping devices to reciprocate eye contact enables users to effectively address devices, infer device attention, and target control actions.
