Primes¶
- Perception Action Loop
- Human-computer interaction. Direct-manipulation interfaces work because they tighten the loop; input latency degrades performance because it loosens it.
This sourceShows input lag degrades target-acquisition performance (movement time and error rate rise sharply with latency) — direct-manipulation works by tightening the loop, latency loosens it.

MacKenzie and Ware show that input lag degrades target-acquisition speed and accuracy, but say nothing on direct-manipulation interfaces tightening the loop.
“Lag has been shown to degrade human performance in motor-sensory tasks on interactive systems.”
- Human-computer interaction. Direct-manipulation interfaces work because they tighten the loop; input latency degrades performance because it loosens it.
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.
