Visual Testing: It’s Not What You Look At, It’s What You See
summary
Claim: testers routinely miss UI changes because of inattentional blindness and pattern-filling; human attention needs a reset every ~10 minutes and only ~2% of people multitask well. Concrete techniques: use mind maps (Xmind.net), crowdtest cycles (Applause/youtest), and image-baseline comparison with visual tools (Apple II tools) to detect layout and color regressions. Demonstrations include a gumball guess average (651) vs actual 665, a Perfection game that fails under distraction, and Slidebot for slide images (Slidebot.io).
