C1.15
Pointing Device Metrics and Throughput
Cards in this group · 5
- C1.15.1Throughput captures a pointing device's speed-accuracy tradeoff, not speed alone
- C1.15.2Fitts' law models movement time as a logarithmic relation to target distance and width
- C1.15.3Effective width is recalculated from endpoint distribution rather than nominal width
- C1.15.4Throughput across tasks and postures cannot be compared directly
- C1.15.5Mean completion time alone hides speed-accuracy differences
