Just-in-time automated counseling for physical activity promotion.
Preliminary results from a field study into the efficacy of automated health behavior counseling delivered at the moment of user decision-making compared to the same counseling delivered at the end of the day are reported. The study uses an animated PDA-based advisor with an integrated accelerometer that can engage users in dialogues about their physical activity throughout the day. Preliminary results indicate health counseling is more effective when delivered just-in-time than when delivered retrospectively.
