Short answer

Incorporate explicit design considerations for efficiency, effectiveness, satisfaction, error prevention, accessibility, and understandability when developing mobile applications intended for visually impaired users.

Field: User-Centred Design
Source: International Journal of Interactive Mobile Technologies (iJIM) (2020)
Method: Systematic Literature Review (SLR)
Evidence: Strong effect

Prioritizing efficiency, effectiveness, satisfaction, error reduction, accessibility, and understandability in mobile application design significantly improves the user experience for individuals with visual impairments. This user-centred design research insight is drawn from a 2020 study published in International Journal of Interactive Mobile Technologies (iJIM). Using Systematic literature review (slr), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate explicit design considerations for efficiency, effectiveness, satisfaction, error prevention, accessibility, and understandability when developing mobile applications intended for visually impaired users.

Six Usability Dimensions Enhance Mobile App Satisfaction for Visually Impaired Users

International Journal of Interactive Mobile Technologies (iJIM) · 2020

Key Findings

01Efficiency is a critical usability dimension.
02Effectiveness directly impacts user satisfaction.
03User satisfaction is a primary outcome measure.
04Minimizing errors enhances the user experience.
05Accessibility is paramount for this user group.

Application

Design takeaway

How to apply

When designing or evaluating mobile applications for visually impaired users, use these six dimensions as a framework for feature development and user testing.

Project actions

01When researching for your design project, look for studies that focus on specific user groups with unique needs.
02Consider how you will measure 'satisfaction' in your own user testing.

Method & Evidence

AimTo identify key usability dimensions that significantly impact the satisfaction of visually impaired users with mobile applications.

MethodSystematic Literature Review (SLR)

ProcedureThe researchers conducted a systematic review of existing literature to identify and consolidate usability dimensions relevant to mobile applications used by individuals with moderate to severe visual impairments.

ContextMobile application development for visually impaired users.

Variables

IV["Usability dimensions (efficiency, effectiveness, satisfaction, errors, accessibility, understandability)"]

DV["User satisfaction with mobile applications"]

CV["Type of mobile application","Severity of visual impairment"]

Strengths & Limitations

Strengths

+Comprehensive review of existing literature.
+Focus on a specific, often underserved, user group.

Limitations

The findings are based on a review of existing research, which might have its own limitations in terms of methodology or scope.

Reliability & validity

The reliability of the findings depends on the quality and consistency of the studies included in the SLR. Validity is enhanced by the systematic nature of the review process, aiming to capture a broad range of relevant research.

Think critically

How might the relative importance of these six dimensions shift for users with different levels of visual impairment (e.g., mild vs. severe)?

Design Principles

"Inclusive design prioritizes the needs of diverse user groups, ensuring digital products are usable and satisfying for all."

Designing for users with specific needs, such as visual impairments, requires a nuanced understanding of usability beyond general guidelines. By focusing on these six dimensions, designers can create more inclusive and effective digital products, expanding their reach and impact.

What This Means for Your Design

When making apps for people who can't see well, focus on making them easy to use, effective, satisfying, error-free, accessible, and understandable. These six things are super important for their happiness with the app.

How to use in your project

1.Reference this study when justifying the importance of specific usability criteria for your target user group, especially if they have particular needs.

Paragraph starter

A systematic literature review by Hussain and Omar (2020) identified six critical usability dimensions—efficiency, effectiveness, satisfaction, error reduction, accessibility, and understandability—that significantly influence the user experience and satisfaction of visually impaired individuals using mobile applications. This underscores the need to tailor usability evaluations and design considerations to the specific needs of diverse user groups.
