How to sync eye-tracking data with DOM events?

WHAT IT TESTS: ability to fuse two real-time data streams with different timestamps and frequencies. OUTLINE: record gaze points with millisecond precision, map to DOM via bounding box lookup, correlate with click events via shared timestamp.

How to diagnose and fix ignored sidebar navigation?

WHAT IT TESTS: ability to connect UX data to technical solutions. OUTLINE: form testable hypotheses (contrast, layout, blocking), propose specific CSS/DOM changes, sketch A/B test plan. RED FLAG: generic suggestions without linking to heatmap patterns.

Fixing text overflow from long localized labels

WHAT IT TESTS: Localization-aware responsive CSS. OUTLINE: Avoid fixed widths, use flexible layouts, allow wrapping or word-break, ellipsis as last resort, pseudo-localize to test.

Using personas to drive technical decisions

WHAT IT TESTS: Connecting user context to engineering choices. OUTLINE: Derive constraints like device, network, accessibility from personas; let them shape framework, payload shape, performance budgets.

Comparing skewed task-time data without a t-test

WHAT IT TESTS: Knowing test assumptions. OUTLINE: t-test assumes normality and is mean-sensitive to outliers; use Mann-Whitney U on ranks; trade-off is it tests distribution shift, not means.
