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

Figure 4

Real-time biofeedback system operation and delays. User movement (action) is captured by sensor(s) and their signals are sent to the processing device for analysis. Analysis results are sent to actuators, which use one of the human modalities to communicate the feedback to the user, who tries to react on it. Users perceive only the entire biofeedback delay (blue dotted line) defined as a sum of all delays in the system. The biofeedback system devices can control only the feedback loop delay, defined as a sum of all communication and processing delays of sensor(s), processing device(s), actuator(s), and communication paths.
