Organize steps so the next action sits comfortably within the thumb zone, avoiding screen corners. Insert planned micro-pauses that give users a breath to look up and perform the step before advancing. This rhythm reduces accidental taps, encourages accurate execution, and acknowledges that real work requires eyes off-screen without losing place or momentum in context.
In loud settings, short on-screen text beats narration. In quiet, hands-busy moments, narration wins. Provide both when possible and let users switch instantly. Keep scripts timed to natural task cadence, avoiding narration that races ahead. Include quick replay controls and waveform-friendly compression so instructions remain clear on basic earbuds and aging, budget-constrained mobile devices.
Use annotated photos, simple line drawings, and arrows that point exactly where eyes should land. Avoid decorative imagery. Favor before/after contrasts and color-coded statuses. Always test on dimmed screens outdoors. The goal is instant recognition: users glance, understand, act, and move. When visuals do the heavy lifting, words can stay short, sharp, and supportive.
