Demonstration of Menu Option 2—determine timing sequence of events from biometrics. The four biometrics are HA (a), HR (b), BR (c) and V_E (d). In this example, the user selected time points T_HR and T_BR to specify the times immediately before a rapid increase in HR and BR, respectively, as shown by the black vertical lines. The user positions a cursor in the window displaying HR data and clicks at T_HR, and then places the cursor in the window displaying the BR data and clicks at T_BR. Then, the software automatically determines and displays the results, which show T_BR occurs 2.9 s before T_HR.
