The Role of High Performance Computing and Communication for Real-Time Biofeedback in Sport

Figure 6

An example of a high dynamic movement: a handball free-throw hand movement measured by a 6-DoF sensing device: (a) accelerometer and (b) gyroscope signals are sampled with 1024 Hz. Signal spectrum (DFT) is calculated on the sequence of 2048 data points inside the 2 s time frame for (c) accelerometer and (d) gyroscope. Signal bandwidth is measured and calculated by the relative cumulative energy criterion (99%) for (e) accelerometer and (f) gyroscope.
