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.
