Summary

This pilot study is a small sample (N=46) 16-week clinical trial with a follow-up after 24-weeks among sedentary adults \>60 y with a BMI \>25 kg/m2 to tests the impact of a hybrid artificial intelligence behavior change system (Companion) on physical activity. Participants will be randomized to a control and intervention group. All participants will engage in a proven supervised exercise program from week 1 to 16. Only the intervention group will receive Companion from week 1 to 16.

Companion

Companion integrates wearable sensing with the smartphone to develop a behavior-aware, virtual system that uses a "human-in-the-loop" approach to enable meaningful two-way communication. Companion builds rich models of typical behavior using sensors and context sensitive ecological momentary assessment to deliver intervention components and behavior change strategies using socially engaging, contextually salient, and tailored text-message conversations in near-real-time.
