Table 3 The real-time myocontrol performance metrics calculated for each subject and control method
Metric | Abbreviation | Summary |
|---|---|---|
Completion rate [%] | \(CR\) | The proportion of targets which are successfully reached |
Completion time [s] | \(CT\) | The total time from the start of the task to the target being reached, averaged across all targets (excluding failed attempts) |
Path Efficiency [%] | \(PE\) | The ratio between the length of the optimal (straight line) path from the origin to the target and the distance traversed by the cursor, averaged across all targets |
Overshoot | \(O\) | Total number of occurrences during the test wherein the cursor leaves the target prior to dwell time elapsion, divided by the total number of targets |
Throughput [bits/s] | \(T\) | The ratio between the (target-wise) index of difficulty and the (target-wise) completion time averaged across all successfully reached targets |
