AI spatial-audio companion that helps blind and low-vision users explore indoor spaces
Directional sound cues are positioned around the listener so the location of nearby objects and obstacles is conveyed through hearing rather than sight.
Ask spoken questions about your surroundings and receive AI-generated descriptions, such as what items are placed on a table or counter.
Depth sensing plus AI helps identify and locate objects and explore paths around indoor obstacles, with the caveat that this remains an experimental capability.
Control the app and ask questions hands-free by speaking to Siri, so the phone does not need to be handled during use.
