Method
Review and analysis of six Fitts's law studies.
Claims used
- Fitts's law models the time needed to point to and select a target and is widely used in HCI.
Limitations: The studies reviewed were inconsistent, making cross-study comparisons difficult.
Extracted principles
- Targets should be large enoughNot tested
Pointer and touch targets should be at least 24 × 24 px because selection time depends on target size and distance.
