Websites designed with accessibility principles in mind demonstrate improved usability for all users, not just those with disabilities. This user-centred design research insight is drawn from a 2014 study published in Research Showcase @ Carnegie Mellon University (Carnegie Mellon University). Using Framework development and multi-tool assessment, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design and build websites with accessibility standards as a core requirement, as this will inherently improve the usability for all users.

01

Key Findings

  • 01Accessible websites tend to be more usable.
  • 02A framework was developed to measure website usability by integrating accessibility and usability assessment tools.
02

Application

Design takeaway

Design and build websites with accessibility standards as a core requirement, as this will inherently improve the usability for all users.

How to apply

When designing any digital interface, use accessibility guidelines (like WCAG) as a baseline for usability, and employ a combination of automated tools and user testing to validate both aspects.

Project actions

  • 01When evaluating a website, consider how its accessibility features (or lack thereof) might affect its overall ease of use.
  • 02Use accessibility checklists as a starting point for usability testing.
03

Method & Evidence

AimTo investigate whether enhancing website accessibility positively impacts overall website usability.
MethodFramework development and multi-tool assessment
ProcedureA five-stage methodology was employed to develop a framework for assessing website usability, incorporating seven selected tools to measure both accessibility and usability metrics.
ContextWeb design and digital product development

Variables

IVWebsite accessibility features
DVWebsite usability metrics
CVWebsite content, design complexity, user task complexity
04

Strengths & Limitations

Strengths

  • +Addresses a practical need for convincing stakeholders about the value of accessibility.
  • +Proposes a structured framework for evaluation.

Limitations

The specific tools and framework used in the study might not be universally applicable or exhaustive.

Reliability & validity

The reliability of the findings would depend on the consistency of the assessment tools used and the validity would be strengthened by user testing to confirm the perceived usability improvements.

Think critically

To what extent can automated accessibility checks fully predict or guarantee improved usability, and what role does subjective user experience play?

05

Design Principles

"Inclusivity in design leads to universal usability."

Prioritizing accessibility in web design can lead to a more intuitive and efficient user experience, potentially increasing user satisfaction, engagement, and conversion rates. This insight encourages a holistic approach to design where inclusivity benefits the entire user base.

06

What This Means for Your Design

Making websites easy for people with disabilities to use also makes them easier for everyone to use.

Quick Cite

Paragraph starter

Research indicates a positive correlation between website accessibility and usability, suggesting that designing for users with disabilities inherently enhances the experience for all users. This implies that incorporating accessibility standards, such as WCAG, should be a fundamental aspect of user-centred design to ensure a more intuitive and effective digital product.
