Are we synchronized? Measure synchrony in team sports using a network of wireless accelerometers

Movements synchronism is a key parameter for team sports. To determine whether human movements in rowing are synchronous or not, we developed a system that acquires signals through accelerometers and compares those signals using correlation. System components are tuned to reduce the delay between the time at which the action occurs and the one the system produces the output. We present an application to help training synchronized movements and use it to test the system with elite rowing athletes. The system generates the output within 500 ms from the moment of the movement.
