Turn the experiment into a decision
01
What happened
Large nearby targets are generally faster to acquire than small distant targets.
02
Why it happened
Smaller targets and longer pointer travel demand more precision and correction.
03
Where to apply it
Primary actions, mobile controls, table actions, toolbars and repeated workflows.
04
How to validate it
Measure target acquisition time and missed clicks with realistic devices and task frequency.
