User Interfaces for Wearable Computers : Development and Evaluation

It examines user interfaces for wearable computers and analyses the challenges imposed by the wearable computing paradigm through its dual-task character. He discusses solutions for the development and evaluation of user interfaces which can be used in dual task scenarios. The author presents fundamental research results and introduces a special software tool as well as the “HotWire” evaluation method to facilitate user interface development and evaluation. Based on the findings of different end-user experiments conducted to study the management of interruptions with gesture and speech input in a wearable computing scenario, the author derives design guidelines and general constraints for forthcoming interface designs.
