General Electric is using biometric sensors to help athletes monitor their training performance.
The athletes are able to use the biometric sensors and LEDs to outline their performances with light. The sensors track an athlete's acceleration, muscle activity and heart rate while performing. To capture all the athletes' movements, GE added LE lights to the biometric sensors so that it looks like the athletes are painting with their movements. The information from the sensors is converted into analogue information to be seen as red, green and blue LED lights. The athletes' performances were recorded with long-exposure photography and the LED light animations were added in slow-motion shots.
Athletes are able to use the recorded information to see which parts of their routine causes their heart rate to spike or uses the most muscle activity.
