The real-time myocontrol performance metrics calculated for each subject and control method

Metric	Abbreviation	Summary
Completion rate [%]	$\mathit{CR}$	The proportion of targets which are successfully reached
Completion time [s]	$\mathit{CT}$	The total time from the start of the task to the target being reached, averaged across all targets (excluding failed attempts)
Path Efficiency [%]	$\mathit{PE}$	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
