- Evidence
- Moderate effect
Existing design guidelines and checklists for mobile phones aimed at older adults predominantly focus on visual and haptic elements, neglecting crucial aspects of textual interface usability, and have not fully adapted to the complexities of smartphone technology. This human factors research insight is drawn from a 2017 study published in International Journal of Human-Computer Interaction. Using Expert coding and content analysis of published design guidelines and checklists., researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for older adults, move beyond basic visual and tactile considerations to deeply integrate and test the usability of text entry, font clarity, and overall textual navigation, especially for smartphone interfaces.
Mobile phone design guidelines for older adults lag behind technological advancements, particularly in textual interface usability.

Key Findings
- 01Guidelines primarily address visual and haptic aspects (e.g., contrast, button size/type).
- 02Textual interface elements (e.g., text entry, font, feedback) are underrepresented.
- 03Guidelines have become more comprehensive over time, but still lack empirical validation.
- 04Smartphone-specific guidelines emphasize screen, touchscreen, text, and exterior, while feature phone guidelines focus on keypad and menus.
Application
Design takeaway
When designing for older adults, move beyond basic visual and tactile considerations to deeply integrate and test the usability of text entry, font clarity, and overall textual navigation, especially for smartphone interfaces.
How to apply
When developing design guidelines or checklists for products targeting older adults, ensure they explicitly cover text input methods, font readability, and screen navigation, and plan for user validation studies.
Project actions
- 01When researching design for older adults, look for guidelines that cover more than just physical attributes.
- 02Consider how users will input text and read information on your design, not just how they will press buttons.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Systematic analysis of a range of relevant guidelines.
- +Identifies specific areas of weakness in existing design guidance.
Limitations
The guidelines analyzed are from before 2015, so they might not reflect the latest advancements in mobile technology or current best practices for older adults. The expert coding is subjective and might miss nuances.
Reliability & validity
Reliability could be improved by having multiple experts code the same guidelines and comparing their results. Validity is addressed by the expert coding of established guidelines, but direct user validation is noted as a limitation and future need.
Think critically
Given the rapid pace of technological change, how can design guidelines be made more adaptable and future-proof to ensure they remain relevant for evolving user needs and device capabilities?
Design Principles
"Prioritize comprehensive usability evaluation that includes textual interaction and is empirically validated for the target demographic."
As mobile technology continues to evolve, it's critical that design guidelines keep pace to ensure products are truly accessible and usable for all demographics, especially aging populations. Failing to address evolving interface elements like touchscreens and text entry can lead to exclusion and frustration for a significant user group.
What This Means for Your Design
Older people's phone design guides are good at telling you how big buttons should be or how bright the screen should be, but they don't say enough about how easy it is to type text or read words, especially on newer smartphones. These guides also haven't been proven to actually work well with older users.

Paragraph starter
Research indicates that current design guidelines for mobile phones targeting older adults often overlook critical aspects of textual interface usability, focusing instead on visual and haptic elements. This oversight is particularly relevant when designing for smartphones, where complex text entry and navigation are paramount. Therefore, any design project aiming for true inclusivity must prioritize and empirically validate solutions for text readability and input ease.
