Changing your bandage

• Pictographs improve understanding and recall. Adding simple pictures to health instructions helps people — especially those with limited reading skills — understand and remember them (Houts et al., 2006). Each step here is one picture, one action.
• Language access without walls of text. The pictures carry the meaning. Short captions and audio come in English, Spanish and Vietnamese. Real deployments need qualified human review of every translation.
• Learner control (Mayer). People tap a step to hear it, at their own pace, or play all steps in order. Captions can be turned off for a picture-only view.
• Built for a caregiver. The steps are written for whoever does the dressing change; the warning panel is the same in every language and links to one call button.

COM-B target: Physical and psychological capability (how to do each step), Physical opportunity (supplies ready), Reflective motivation (knowing when to call).

Persona tuned for: “Mr. Tran, 71” — prefers Vietnamese, limited reading in any language; his wife changes the dressing.

How HealthLiteracyCopilot would make it: HealthLiteracyCopilot would turn a nurse-approved wound-care guide into a step-by-step pictogram sequence (from a reviewed pictogram library, not free-form image generation), then create the captions and audio scripts with clinical-anchor checks and qualified human sign-off. It would be checked with PEMAT-P (visual aids, actionability) and a “picture-only” comprehension probe with simulated low-literacy readers (simulated participants, not patients).

What a pilot would measure: correct return demonstration at the follow-up visit; infection-related calls made early (not late); wound infection readmissions. Measures a pilot would track, not results or promised effects.
