Research project

Pattern Recognition methods in digital sports applications

The goal of this research project is to explore the application of methods from pattern recognition to biomechanical and medical problems in the area of digital sports in close collaboration with sports article industry.

A main aspect is hereby the investigation and development of embedded support systems in the area of sports. Embedded systems are omnipresent in many aspects of daily live, e.g. in modern cars, mobile phones or medical implants. Due to the increasing miniaturization of sensors, such systems are also imaginable in the area of sports, where they might support or help athletes. Today it is already possible e.g. to measure the heart rate or speed of a runner and provide this information to the athlete.

Within the scope of this project such concepts shall be explored and improved. To achieve this goal, methods from pattern recognition will be employed to develop novel ways of processing and classifying biomechanical data. The focus will be on the analysis of human movements using kinematic and kinetic parameters, as well as the assessment of muscle activity using electromyography (EMG).

Subsequently the integration of different sensors into sportswear and potential embedded processing methods of the measured signals will be studied. The concepts from pattern recognition will then be used on the embedded systems to extract information of interest from the data and provide it to the user. Examples for such information include the degree of fatigue or assessing the health aspect of certain motion sequences, e.g. running. This will lead to the invention of lightweight, mobile support systems, which can directly support, guide or motivate athletes and might help to prevent possible injuries.
