Abstract
Regular physical exercise is essential for overall health; however, it is also crucial to mitigate the probability of injuries due to incorrect exercise executions. Existing health or fitness applications often neglect accurate full-body motion recognition and focus on a single body part. Furthermore, they often detect only specific errors or provide feedback first after the execution. This lack raises the necessity for the automated detection of full-body execution errors in real-time to assist users in correcting motor skills. To address this challenge, we propose a method for movement assessment using a full-body haptic motion capture suit. We train probabilistic movement models using the data of 10 inertial sensors to detect exercise execution errors. Additionally, we provide haptic feedback, employing transcutaneous electrical nerve stimulation immediately, as soon as an error occurs, to correct the movements. The results based on a dataset collected from 15 subjects show that our approach can detect severe movement execution errors directly during the workout and provide haptic feedback at respective body locations. These results suggest that a haptic full-body motion capture suit, such as the Teslasuit, is promising for movement assessment and can give appropriate haptic feedback to the users so that they can improve their movements.
Highlights
Sufficient physical activity has significant health benefits, improves overall wellbeing, and decreases the general risk of death [1]
The current system provides haptic feedback based on the detected execution errors; the effectiveness of the haptic feedback was not evaluated within this study and should be done in future work
We developed a Unity application to create a database for training and testing support vector machines and probabilistic movement models
Summary
Sufficient physical activity has significant health benefits, improves overall wellbeing, and decreases the general risk of death [1]. Various professional societies recommend guidelines on physical activity and sedentary behavior required to offer significant health benefits and mitigate health risks [2,3]. Guthold et al [4] further observe that physical activity decreased over time in high-income countries. These results show the importance of motivating people to become more physically active. To improve health outcomes, it is necessary to engage in regular physical activity, but it is essential to perform sport exercises correctly and prevent injuries due to improper exercise execution
