B1.12
Effective width of two-dimensional targets
Cards in this group · 4
- B1.12.1Two-dimensional targets require both width and height; minimum-edge and projected-width models differ
- B1.12.2Approach angle changes effective width, so the same button differs by direction
- B1.12.3Elongated targets are easier along the long axis than the short axis
- B1.12.4Hit area, not visual size, determines difficulty when they differ
