Usability testing of multimodal feedback interface and simulated collision-avoidance power wheelchair for long-term-care home residents with cognitive impairments

Rosalie H. Wang, PhD, BSc (OT), et al.


Figure 1. Setup and operation of simulated collision-avoidance power wheelchair with multimodal feedback. Dashed lines mark eight obstacle zones. “AC” denotes key for “All Clear” command. (1) Obstacle at front left side; (2) investigator presses key on computer that corresponds to location of obstacle; (3) power wheelchair movement stops; and (4) delivery of auditory, visual, and haptic feedback.

Power wheelchair users may benefit from new devices to improve independence and safety. Features like collision-avoidance and steering assistance are relevant for people with physical and cognitive disabilities related to conditions linked to aging, accident, or injury. We developed a simulated collision-avoidance power wheelchair with a joystick interface with audio, visual, and tactile feedback to guide movement away from nearby obstacles. We tested the device with older adults with cognitive impairments in long-term-care homes. Users supported the new features and added guidance. The device was easy to use and assisted users to reach indoor mobility goals.
