Some veterans with disabilities are denied powered 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 collisions. Therefore, it could help people with mobility impairments who also have difficulties seeing, using their arms and hands, or learning driving skills, including veterans with multiple injuries. In this project, clinical evaluation of the DSS was performed in a controlled laboratory setting with blindfolded nondisabled individuals. Results indicate that the participants were able to reach the assigned target without hitting obstacles when using the navigation assistance from the DSS. These findings suggest that the DSS can be a viable powered mobility solution for wheelchair users with visual impairments.
