Domain-specific¶
- Fitts's Law
- The trade-off is a physical-informational limit on aimed movement, not a learnable-away inefficiency. Not a pair of universal constants. The intercept a (response-initiation overhead) and slope b (inverse channel throughput) are fit per effector and modality — a mouse, a stylus, an eye tracker each have their own
This sourceSets the standard procedure for pointing-device evaluation and shows that Fitts constants and throughput are properties of one device-and-effector channel; it defines throughput as effective index of difficulty over movement time and argues against using the reciprocal of the regression slope.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
