Development of a Biofeedback Approach Using Body Tracking with Active Depth Sensor in ASBGo Smart Walker

There is a considerable number of people with balance problems. Thus, the development of devices that can support and aid patients these patients is a very important question in our days. One important point to take into account during their treatment is which relevant information should be presented to them to improve their motivation and movement control. Biofeedback is an important tool since it shows to the patient his/her real performance [1]. This article tackles the challenge of integrating such a tool in a smart walker. It presents an application that was developed to aid patients with balance problems while walking assisted with the Adaptive System Behavior Group (ASBGo) smart walker (SW). Through a built-in Active Depth Sensor (ADS), it is possible to recognize the upper body and extract data about the user's performance. Such information is processed with the developed application and displayed in a graphic's interface in real time. Results show the high potential of this application to be used during a clinical trial using the smart walker as a rehabilitation tool.
