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.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
