This paper presents a wearable training system designed to facilitate the learning process of proper movement patterns in sports training. The system implements a gesture user interface and real-time biofeedback. To demonstrate the concept of the proposed real-time biofeedback training system, an application for golf swing training is developed. The application implements the system using smartphone motion sensors and audio biofeedback and aids golfers in correcting unwanted head movements during a golf swing. The application is driven by a gesture user interface. During the golf swing, the application provides users with real-time audio feedback that signals head movement errors. The field test results show that the developed application can be used as an efficient tool in golf swing training.

Motion tracking systems, in connection to the biomechanical biofeedback, help in accelerating motor learning. Requirements about various parameters important in real-time biofeedback applications are discussed. Special focus is given on feedback loop delays and its real-time operation. Optical tracking and inertial sensor tracking systems are presented and compared. Real-time sensor signal acquisitions and real-time processing challenges, in connection to biomechanical biofeedback, are presented. This paper can serve as a starting point for determining the adequate combination of technical equipment and its specifications that work favorably for the operation of the planned real-time biofeedback application.

This paper presents a system that enables a real-time analysis of motion patterns and provides the user with real-time information on the performance and accuracy of an executed set of motions. This information can be used to identify individual segments of improper motion early in the learning process, thus preventing improperly learned motion patterns that can be difficult to unlearn or correct once they are fully learned. The primary purpose of our system is to serve as a general tool in the research on how different feedback modalities affect the process of motor learning, for example, in sports or physiotherapy. The key advantages of the system are high-speed and high-accuracy tracking as well as its flexibility, as it supports various types of feedback (auditory and visual, concurrent or terminal) and can be used in various real-world applications.
