  • Aim User, caregiver, and prescriber perspectives

    • 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 User, caregiver, and prescriber perspectives

  • 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 User, caregiver, and prescriber perspectives

  • 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 User, caregiver, and prescriber perspectives

  • 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.
