Research Projects

As part of the BMBF-funded project "Multimodal Immersive Learning with Artificial Intelligence for Psychomotor Skills" (MILKI-PSY), motion sequences in volleyball, handball, football, and badminton were recorded using a motion capture system (full body suit with integrated sensor system for motion capture). In volleyball and handball motion sequences with various balls were executed. In football and badminton weights were attached to participants ankles/wrists in addition to the normal motion execution. In the further course of the project, the collected motion data are to be analysed, by means of different visualisation methods, and individual body part positions are to be analysed with regard to the different research elements.

The BMBF-funded project "Multimodal Immersive Learning with Artificial Intelligence for Psychomotor Skills" (MILKI-PSY) aims to develop learning environments that support the learning of psychomotor skills. Here virtual worlds are combined with digital information and the real world. For this purpose, optimised movement sequences are recorded by trainers or experts with cameras and sensors. Movement models generated from these recordings offer learners a direct comparison of target and actual values. Augmented reality helps to create these immersive training environments.

Within the scope of the BMBF-funded project "Multimodal Immersive Learning with Artificial Intelligence for Psychomotor Skills" (MILKI-PSY), an extended reality (XR) trainer was developed to support learning of the putt in golf. Learners are shown an idealised stroke execution in Microsoft HoloLens 2 Glasses so that their own stroke can be adapted more easily. A first study shows that motor learning in golf is not exclusively promoted by conventional methods, but that innovative methods also produce corresponding training effects. Future long-term studies should examine to what extent the effects of an XR trainer can go beyond the effects of conventional training.

For table tennis players, speed is probably the most relevant conditional skill. The game of table tennis requires quick footwork at the table as well as quick execution of the stroke movement in order to be in the right place at the right time and to execute a stroke flawlessly. In order to meet these requirements, the speed of action of table tennis players must be very pronounced. On the one hand, this involves the actual speed of movement, but also the speed of action, i.e. the ability to act quickly in the game and appropriately according to the situation. The more time the players have for the movement action in a rally, the more controlled the stroke is performed. Efficient footwork is essential for this "gain in time". It is the basis of every stroke in order to be able to stand optimally at the moment of ball contact. Therefore, analyses for footwork techniques with consideration of the stroke technique are increasingly important for players and coaches.

One concrete question that table tennis players, but also coaches and table tennis enthusiasts keep asking themselves is: "After which footwork techniques are points won or lost? Often it is no coincidence that table tennis players are uncertain about this question, because a comprehensive automated game analysis of two table tennis players with regard to winning and losing points does not yet exist in table tennis. Heatmaps are used to analyse the positions of table tennis players. The long-term goal is to develop automated analysis software for table tennis that can also be used to study efficient footwork techniques and interactions between players in the future.

On average, a game athlete changes his/her movement (e.g., jumps, lateral movements, high-intensity runs, etc.) between 500-3000 times during competition at intervals of 2-4 seconds. In sports games, most of these movement changes are in response to a stimulus (e.g., another player’s movement or the ball movement). This skill is defined as agility in the current literature. The term agility encompasses perceptual and decision-making processes and takes the form of a change of speed or a change of direction (COD).

The SpeedCourt by the company Global Speed is a multifunctional diagnostic and training system. It consists of twelve contact plates and by means of the software predefined or randomized running instructions can be shown on the screen.

Based on the requirements of sports games, the SpeedCourt can serve diagnostic purposes and the purpose of training control, especially in the field of multidirectional sports. In addition, it can be used for sport-specific testing to answer cross-disciplinary research questions.
