Aim

    • Explore user, caregiver, and prescriber views on power mobility devices (PMDs) with collision avoidance (CA) technology.
  • Relevance
    • CA technology can facilitate safer mobility for older PMD users with physical, sensory, and cognitive impairments.
    • Little is known about consumers’ perceptions of CA.
method
Method
  • Qualitative research approach was used and thematic analysis was applied to analyze in-depth, semistructured interview data from:
    • 29 PMD users (aged 50+).
    • 5 caregivers.
    • 10 occupational therapists.

Example of intelligent power wheelchair.

results
Results
  • Data analysis identified 3 themes:
    • Useful situations or contexts.
      • Driving backward, avoiding dynamic obstacles, negotiating outdoor barriers, and learning PMD use.
    • Technologydesign issues and real life application.
      • Context awareness, reliability, and user interface specifications.
    • Appropriatenessof collision avoidance technology for a variety of users.
conclusion
Conclusion
  • Most participants supported CA technology.
    • Saw benefits for current users and users with visual impairments.
    • Felt it might be unsuitable for people with significant cognitive impairments.
  • Some participants voiced concerns regarding injury risk.
  • Users expressed desire to maintain driving autonomy, which supports development of collaboratively controlled systems.
