Demonstration of Menu Option 1—selection of time points in biometrics window, and display of corresponding climber video frames. The four biometrics include: (a) hip acceleration (HA); (b) heart rate (HR); (c) breathing rate (BR); (d) minute ventilation (V_E). Climbing video frames (e–g) show three locations of a lead climber while ascending an indoor climbing wall, which correspond to the three time points (T1–T3) in the biometrics data, respectively. After the user positions a cursor in the biometrics window and clicks at a time point in one biometric plot, the software immediately displays the time-matched climbing video frame, and displays time-markers at the selected time point (vertical lines) in all four biometric plots.
