Summary
This summary is machine-generated.

Gamification enhanced visual localization accuracy in retinal prosthesis users but did not improve motion discrimination. User preference and engagement varied by task, suggesting personalized approaches are key for prosthetic vision assessment.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Human-Computer Interaction

Background:

  • Visual function testing for retinal prosthesis users is often cognitively demanding and fatiguing.
  • Gamification strategies may enhance user engagement but their impact on perceptual performance is not well understood.

Purpose of the Study:

  • To investigate the effects of gamification on visual perceptual performance and user experience in Argus II retinal prosthesis users.
  • To determine if gamified visual function tests improve accuracy and engagement compared to traditional methods.

Main Methods:

  • Three Argus II users performed circle localization and motion direction discrimination tasks in both clinical and gamified formats.
  • Gamified versions incorporated scoring, music, and feedback; difficulty was individually calibrated.
  • Performance metrics (accuracy, error) and user experience (enjoyment, attention) were assessed.

Main Results:

  • Gamification significantly improved localization accuracy and reduced angular error.
  • Motion discrimination performance did not improve and showed reduced precision in one user under gamified conditions.
  • Users preferred gamified localization, reporting higher enjoyment and sustained attention; responses to gamified motion were mixed.

Conclusions:

  • Gamification can influence performance and user experience in prosthetic vision testing, with benefits being task-dependent and variable across individuals.
  • Engagement strategies can impact outcomes in tests previously considered objective.
  • Personalized, adaptive gamified tools hold potential for improving prosthetic vision assessment and rehabilitation.
