Swiss AI simulator makes skiers more aerodynamic

A simulator developed by the University of Applied Sciences of Graubünden uses artificial intelligence (AI) to analyse the aerodynamic racing position of skiers and to help them to optimise their posture. The 'digital wind tunnel' is intended to offer a cost-effective, safe and weather-independent alternative to expensive wind tunnel facilities, which are not usually available to young athletes, the Swuiss university said. The system would allow athletes to practise their posture all year round. In a real wind tunnel, turbines generate the airflow. Sensors then measure the level of air resistance for different body positions. This makes it possible to determine which position causes the least drag for the athletes. AI instead of wind In the ‘digital wind tunnel’, athletes stand on skis in front of a green screen. A camera and AI capture and analyse their body posture. The system uses this data to determine how aerodynamic their position is. The athletes can see their position ...
