Digital Image and Video Processing to Motivate Physical Exercise Using a Kinect-Based Module

Abstract:

This work presents the development and results of a prototype to motivate physical exercise in adults through image and video digital processing. The system has a sensor responsible for image and video acquisition (Kinect), a user interface, a dispenser mechanism, and a microprocessor system. By using the Skeletal Tracking of Microsoft Kinect sensor, this prototype identifies the person located in front of the module, recognizes and validates the appropriate execution of predefined physical exercises (squats or lunges), and counts the number of times that the user performs the exercise in a base of time. Once a specific number of exercise repetitions has been properly executed (at least 20 in 120 s), the interface shows the counter result, and the system delivers a water bottle as an incentive. With the use of this module, it is intended to promote physical exercise in an unconventionally and strikingly way.
