Personal Exercise Assistant: Correcting Exercise Posture using Modified Open pose

Abstract

Fitness exercises or yoga are very bene?cial to personal health and ?tness; however, they can also be ineffective and potentially dangerous if performed in correctly by the user. Exercise mistakes are made when the user does not use the proper form, or pose. In our work, we introduce Personal Exercise Assistant, an application that detects the user’s exercise pose and provides personalized feedback. Modified Open Pose is used as a Pose estimator in this application. Open Pose is a pre trained model composed of a multi-stage CNN to detect a user’s posture. This application then evaluates the vector geometry of the pose through an exercise to provide helpful feedback. Pose estimation is a method in which spatial locations of key body joints is calculated using image or video of the person. Modified open pose is a light weight (8bit Quantized version) Open pose. Personal Exercise Assistant works on yoga exercises and supports any Windows or Linux computer with a GPU.
