Cognitive impairments prevent older adults from using powered wheelchairs due to safety concerns, thus reducing their mobility and resulting in increased dependence on caregivers.

Machine vision and learning techniques are described to help prevent collisions with obstacles, and provide reminders and navigation assistance through adaptive prompts.
