Hendrik Witt examines user interfaces for wearable computers and analyses the challenges imposed by the wearable computing paradigm through its dual-task character. He introduces a special software tool as well as the 'HotWire' evaluation method to facilitate user interface development and evaluation. Based on the results 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.

Dr. Hendrik Witt is a senior research scientist at the Centre for Computing Technologies (TZI) at the University of Bremen (Germany). His research interests are in Human-Computer Interaction (HCI) and context recognition.
