Infographics customized with personal health data significantly improve understanding of health status and caregiving burden for individuals with limited health literacy. This user-centred design research insight is drawn from a 2019 study published in The Gerontologist. Using Participatory design and usability testing with 16 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing information displays for users with potential health literacy challenges, prioritize personalization and intuitive visual scaling that aligns with their existing understanding of the context.
Tailored Infographics Enhance Health Comprehension for Dementia Caregivers

Key Findings
- 01Infographics that used intuitive scaling, reflecting the caregivers' perception of dementia as an inevitable decline, were easily comprehensible.
- 02Participants reacted to the infographics by identifying self-management actions they would take to address the health issues presented.
- 03Tailored infographics served as cues for engaging in self-management.
Application
Design takeaway
When designing information displays for users with potential health literacy challenges, prioritize personalization and intuitive visual scaling that aligns with their existing understanding of the context.
How to apply
When designing health information for vulnerable populations, involve users in the design process to ensure the visualizations are understandable and actionable. Consider using personal data to tailor the information.
Project actions
- 01Involve your target users early and often in the design process.
- 02Test different visual representations of data to see what is most clear.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Employed a participatory design approach, ensuring user relevance.
- +Used validated instruments for health assessment.
Limitations
The sample size was relatively small, and the participants were from a specific cultural background, which might limit the generalizability of the findings.
Reliability & validity
The use of validated instruments for health assessment contributes to the validity of the findings. Iterative refinement based on user feedback enhances the reliability of the design process.
Think critically
To what extent can the principles of intuitive scaling and personalized data visualization be applied to non-health-related domains, and what potential challenges might arise?
Design Principles
"Information visualization should be contextually relevant and perceptually aligned with the user's mental model to facilitate comprehension and drive action."
Effective communication of complex health information is crucial for user decision-making and action. Designing information displays that are accessible and relevant to specific user groups can lead to better health outcomes and empower users to take appropriate self-management steps.
What This Means for Your Design
Making health charts and graphs personal and easy to understand can help people know what to do about their health.
