Practical guide

Compare two caption layouts for mobile readability

A caption-layout comparison should test readable text and unobstructed demonstrations on the intended phone view.

A caption-layout comparison should test readable text and unobstructed demonstrations on the intended phone view.

A practical procedure

  1. Use the same clip and transcript in both layouts, including the longest sentence.

  2. Review each layout with the relevant platform controls and product movement visible.

  3. Ask reviewers to read the text and identify the demonstrated detail without pausing.

Worked example: a fictional session

A fictional test compares lower captions with a raised caption band during a latch demonstration and records which version covers the mechanism.

Check the limits

A layout that works in one shot may fail after a camera change.
