Sentra Guide
AI-powered assistive tech for people with visual impairments
Built in three days at Sacramento State's Carlsen Center with two teammates. Sentra uses real-time computer vision to identify nearby objects and obstacles, then speaks audio alerts so the user knows what's around them. We mounted a camera on a white cane to test it as a physical prototype, and reshaped the design around feedback from people with visual impairments, nurses and a retina specialist.
