Designing interfaces with larger, more visually obvious interactive elements and providing clear onboarding processes directly addresses cognitive load and learnability challenges faced by users with intellectual disabilities. This user-centred design research insight is drawn from a 2024 study published in Academic Publication. Using Heuristic evaluation and user testing, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design interactive elements with generous touch targets and clear visual affordances, and implement guided onboarding to ensure users with intellectual disabilities can effectively learn and use digital products.
Enlarging touch targets and intuitive visual cues significantly improve app usability for individuals with intellectual disabilities.

Key Findings
- 01Enlarging the touch surface of buttons improves interaction.
- 02Making button appearance more intuitive reduces abstraction and aids understanding.
- 03Introducing scrolling buttons streamlines navigation.
- 04Onboarding screens facilitate familiarization and independent learning of new functionalities.
Application
Design takeaway
Design interactive elements with generous touch targets and clear visual affordances, and implement guided onboarding to ensure users with intellectual disabilities can effectively learn and use digital products.
How to apply
When designing for users with intellectual disabilities, increase the size of all interactive elements (buttons, links) and use universally understood icons or labels. Develop a step-by-step onboarding process that introduces features gradually and allows users to practice.
Project actions
- 01When testing with users, observe their interactions closely to identify points of confusion.
- 02Document the rationale behind each design change, linking it to specific user needs.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Focuses on an under-researched user group.
- +Employs a practical, iterative design and evaluation approach.
Limitations
The complexity of intellectual disabilities means that a 'one-size-fits-all' design approach may not be effective; individual needs can vary significantly.
Reliability & validity
Reliability could be enhanced by using standardized usability metrics and having multiple evaluators conduct the heuristic review. Validity is strengthened by the inclusion of user testing, which directly assesses real-world usability.
Think critically
To what extent can the design principles identified for users with intellectual disabilities be applied to other user groups experiencing cognitive challenges, such as the elderly or individuals with attention deficits?
Design Principles
"Design for clarity and learnability by simplifying visual language and providing explicit guidance."
This research highlights the critical need to move beyond generic accessibility guidelines and tailor design solutions to the specific cognitive needs of user groups. By focusing on intuitive visual design and supportive onboarding, designers can create digital products that are not only usable but also empowering for individuals with intellectual disabilities, fostering greater independence and inclusion.
What This Means for Your Design
Making buttons bigger and easier to understand, plus adding helpful guides, makes apps much better for people with intellectual disabilities.

Paragraph starter
This research by Esposito et al. (2024) demonstrates that enhancing digital interfaces with larger touch targets and more intuitive visual cues, alongside effective onboarding processes, significantly improves usability for individuals with intellectual disabilities. These findings underscore the importance of user-centered design principles tailored to specific cognitive needs, suggesting that iterative evaluation and adaptation of design patterns are crucial for creating truly accessible digital products.
