Strengths & Limitations

Strengths

  • +Addresses an under-researched area (CVI and assistive tech).
  • +Employs a user-centered co-design approach.

Limitations

Small sample sizes in user research can limit the broad applicability of findings. The specific hardware used (e.g., Apple Vision Pro) might not be accessible or suitable for all potential users.

Reliability & validity

The qualitative nature of the findings and the small sample size may impact the reliability and generalizability. Validity is supported by the iterative co-design process and direct user feedback.

Think critically

Given the small sample size, how might the design solutions need to be adapted for a wider range of individuals with CVI, considering the heterogeneity of the condition?

05

Design Principles

"Augmenting higher-order visual processing through personalized XR interfaces can significantly enhance environmental interaction for individuals with CVI."

As CVI becomes a more prevalent cause of vision impairment, there is a critical need for assistive technologies that go beyond traditional visual aids. This research highlights how advanced XR devices can be tailored to support the unique visual processing challenges associated with CVI, opening new avenues for design in assistive technology.

06

What This Means for Your Design

Smart glasses can help people with CVI (a type of vision problem that affects how the brain sees) to understand their surroundings better by helping them find things, read, talk to people, and feel less overwhelmed.

How to use in your project

  • 1.Use this research to justify the need for a particular assistive technology or to inform the design of features that address specific user needs related to visual processing.
