Short answer
When designing for users with limited literacy, focus on creating icons that are immediately understandable through visual representation of actions and objects, rather than relying on abstract symbols or text.

Designing mobile interfaces for users with low literacy requires icon sets that are concrete, simple, detailed appropriately, and contextualized, often incorporating visual cues like hands manipulating objects. This user-centred design research insight is drawn from a 2010 study published in Bergen Open Research Archive (BORA) (University of Bergen). Using Prototyping and heuristic evaluation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for users with limited literacy, focus on creating icons that are immediately understandable through visual representation of actions and objects, rather than relying on abstract symbols or text.
Iconography for text-free mobile interfaces should prioritize concreteness and context.

Key Findings
- 01Concreteness, low complexity, balanced detail, and action elements in icons aid user understanding.
- 02Consistency and low complexity were positively received by evaluators.
- 03Icons depicting hands manipulating objects, providing context, received positive feedback.
- 04Concrete icons are more intuitive than abstract ones.
- 05Users rely on expectations of function placement within an interface.
Application
Design takeaway
When designing for users with limited literacy, focus on creating icons that are immediately understandable through visual representation of actions and objects, rather than relying on abstract symbols or text.
How to apply
When developing interfaces for diverse user groups, conduct user research to gather visual concepts and test icon designs for clarity and intuitiveness, especially in contexts where text literacy is not assumed.
Project actions
- 01When designing icons, sketch out many ideas and get feedback from potential users.
- 02Consider how users might expect to find certain functions on a mobile device.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Directly addresses a significant accessibility gap in technology.
- +Employs user-generated content (drawings) to inform design.
- +Utilizes a recognized evaluation method (heuristic evaluation).
Limitations
The icons developed might not be universally understood across different cultures or age groups. The effectiveness of the heuristic evaluation depends on the expertise of the evaluators.
Reliability & validity
Reliability could be improved by using a larger, more diverse sample of users for icon interpretation and by having multiple evaluators conduct the heuristic review. Validity is supported by the use of user-generated concepts and a structured evaluation process.
Think critically
To what extent can icon-based interfaces truly eliminate the need for text, and what are the inherent limitations of relying solely on visual cues for complex functionalities?
Design Principles
"Design for accessibility by prioritizing clear, concrete, and contextual visual communication in interfaces."
This research highlights a critical need for accessible design in mobile technology, moving beyond text-based interactions. By understanding the principles of icon design for illiterate users, designers can create more inclusive products that broaden market reach and enhance user experience for a significant global population.
What This Means for Your Design
To make a phone app easy to use for people who can't read well, use pictures (icons) that clearly show what they do, like a picture of a hand holding a phone for calling. Make the pictures simple and show them in a way that makes sense.
How to use in your project
- 1.Use the findings on icon characteristics (concreteness, context, action elements) to justify design choices for your own interface prototype.

Paragraph starter
The design of the mobile interface prototype was informed by research indicating that icons for users with low literacy should prioritize concreteness, low complexity, balanced detail, and the use of action elements. Specifically, visual representations of hands manipulating objects were incorporated to provide context, a strategy that received positive feedback during heuristic evaluation. This approach acknowledges that concrete icons are more intuitive than abstract ones and that users often rely on established expectations for interface navigation.
