Clinical evaluation of semiautonomous smart wheelchair architecture (Drive-Safe System) with visually impaired individuals

Vinod Sharma, PhD, et al.


Sharma Figure.

Some veterans with disabilities are denied pow- ered mobility because they lack the visual, motor, and/or cognitive skills required to safely operate a powered wheelchair. The Drive-Safe System (DSS) is designed to help power wheelchair users avoid col- lisions. Therefore, it could help people with mobility impairments who also have difficulty seeing, using their arms and hands, or learning driving skills, including veterans with multiple injuries. In this pro- ject, we clinically evaluated the DSS in a controlled laboratory with people with visual impairments. When using the DSS navigation assistance, the par- ticipants were able to reach the assigned target with- out hitting obstacles. Participants were also able to easily understand and use the DSS. These findings suggest that the DSS is a practical powered mobility solution for wheelchair users with visual impairments.
