How to use your inhaler with a spacer
A 1-minute video. Watch it, pause it, or read along. The spacer helps more medicine get to your lungs, not stuck in your mouth.
Video. Press Space or K to play or pause. Press the left or right arrow to go back or forward 5 seconds.
Quick check
You pressed the inhaler and breathed in slowly. Which step comes next?

Why this works — evidence, behavior-change coding, and how HealthLiteracyCopilot builds it
Evidence basis
- Demonstration beats description for a motor skill. Inhaler technique is a physical skill; showing the steps uses Mayer's multimedia principles (words + pictures, narration rather than on-screen text, signaling of the current step, segmenting into learner-paced chapters).
- Embedded comprehension check. The pause question applies the teach-back idea (AHRQ Health Literacy Universal Precautions Toolkit) to a video: the viewer retrieves the next step instead of just watching it.
- Pharmacist hand-off. Inhaler errors are common; the video ends by pointing to a free in-person technique check rather than claiming the video is enough.
Behavior Change Techniques (BCT Taxonomy v1)
| BCT | Where |
|---|---|
| 6.1 Demonstration of the behavior | Whole animation |
| 4.1 Instruction on how to perform the behavior | Narration + step card |
| 8.1 Behavioral practice/rehearsal | "Which step comes next?" pause |
| 5.1 Information about health consequences | Rinsing prevents thrush |
| 3.1 Social support (unspecified) | Pharmacist technique check |
COM-B target
Capability (physical skill + psychological knowledge of step order). Opportunity is addressed with the pharmacist prompt.
How HealthLiteracyCopilot would generate, personalize and assess it
- Generate: storyboard → scene graph rendered as Compiled Video (HealthLiteracyCopilot’s own HTML/SVG + TTS renderer; no video model) → narration script at the persona's reading level → narration voiced with a disclosed synthetic voice → timed cue file (WebVTT) → audio description track.
- Personalize: the author picks the character, language and device version (valved holding chamber vs. plain spacer, controller vs. rescue) for the audience. Each version is reviewed. No personal health information is used.
- Assess: PEMAT-A/V understandability and actionability, CDC Clear Communication Index on the script, and a WCAG 2.2 media checklist (captions, audio description, pause, flashing, contrast). Simulated viewers (simulated participants, not patients) flag the step most likely to confuse, for human review.
What a pilot would measure
Proximal: correct answer to the step-order question, and self-rated confidence. Distal: inhaler technique checked by a pharmacist, controller refill adherence (proportion of days covered), and asthma-related ED visits. Measures a pilot would track, not results or promised effects.
