SCENARIO The health and wellness behavior change intervention for childhood obesity where a humanoid robot is employed to work collectively with a smart TV, smart refrigerator, a wearable activity monitoring wristband, and a smart phone device of choice. The IoT-based persuasive system interacts with the human subject (a child) throughout the day. The robot has routine dialogue with the child subject aimed at motivating him or her toward behavior change for weight loss and increased physical activity. The wearable wristband is used for recording the subject's physical activity throughout the day and storing it to a cloud-hosted central database. The humanoid robot is able to tap into the collective intelligence gleaned by sensors in the smart phone and the wearable wristband to draw insightful conclusions about how the child can refine his or her behavior to meet the target physical activity goals. A smart refrigerator tracks and records the subject's food selection choices. The child is able to interact with the smart TV to participate in a social virtual community where other like-minded children interact together to support each other on their competitive health and wellness goals. The smart TV features an application that affords the participating children interactive gameplay through a Kinect sensor device in a bid to motivate indoor physical activity as well. The smart TV game also has access to the child's profile and outdoor physical activity. Collectively, these devices interact together and share data solely for the purpose of supporting the participating child in his or her quest for weight loss.
