Table 6.

Comparison of accuracy between wrist-worn sensors and chest-worn sensors in all five scenarios (recorded simultaneously in the same five sessions). Note that for Scenario 2, precision and recall were calculated for all events longer than 15 seconds with over 60% of overlap. In addition, scenario 3 is the mean measurements of 2 minute contingency windows.
