Application

Design takeaway

Integrate end-users with vision loss throughout the entire design lifecycle and focus on qualitative usability assessments alongside performance metrics when developing XR assistive technologies.

How to apply

When designing any assistive technology, especially those involving immersive or augmented realities, conduct iterative user testing with the target demographic and gather feedback on subjective experience and ease of use.

Project actions

  • 01Consider how XR could be used to assist users with specific sensory or physical challenges.
  • 02When evaluating a design, think about both how well it performs a task and how easy and pleasant it is to use.

Method & Evidence

AimWhat is the current state of research on Extended Reality (XR) for understanding and augmenting vision loss, and what are the key areas for future development?
MethodSystematic Literature Review
ProcedureA systematic review of 227 publications from 106 venues was conducted, focusing on studies that used XR to augment residual vision or study restored vision, and included quantitative evaluation with end-users.
Sample227 publications
ContextAssistive technology for visual impairment, human-computer interaction, neurotechnology.

Variables

IVType of Extended Reality (XR) technology used (e.g., VR, AR), specific assistive function.
DVUser performance (e.g., task completion time, accuracy), user usability (e.g., perceived ease of use, satisfaction), understanding of vision loss.
CVSeverity and type of vision loss, specific end-user characteristics, experimental environment.
04

Strengths & Limitations

Strengths

  • +Comprehensive review of a large number of publications.
  • +Focus on studies with quantitative evaluation and end-user involvement.

Limitations

The scope of the review might not capture all forms of XR application or all types of vision loss; specific technological limitations of current XR hardware were not the primary focus.

Reliability & validity

The reliability of the review is supported by its systematic methodology. Validity is enhanced by the broad sampling across disciplines and the requirement for quantitative evaluation with end-users, though the focus on specific study criteria might limit the scope.

Think critically

Given the rapid advancement of XR technology, how can designers ensure that the assistive tools they create remain relevant and effective as the underlying technology evolves?

05

Design Principles

"Involve diverse end-users from the outset and prioritize holistic usability in the design of assistive technologies."

This research highlights the critical role of XR in developing assistive technologies for visual impairments. Designers and engineers can leverage XR to create more effective tools that not only aid users but also provide valuable data for further research into vision and its restoration.

06

What This Means for Your Design

New virtual and augmented reality tools can help people with poor eyesight see better and help scientists learn more about how vision works, but we need to test these tools more in real life and involve the people who will use them right from the start.

How to use in your project

  • 1.Reference this study when discussing the potential of emerging technologies like XR for assistive design, particularly for sensory impairments.
  • 2.Use the findings on user involvement and usability assessment to inform your own design process and evaluation methods.
