title: A handheld animated advisor for physical activity promotion.
abstract: We have developed an animated PDA-based advisor that can engage sedentary adults in dialogues about their physical activity throughout the day. An integrated accelerometer enables the advisor to initiate interactions and provide real-time feedback. Results of preliminary usability testing of interaction modalities are presented and a planned efficacy study using free-living sedentary adults is described.
