Title: METHOD AND DEVICE FOR VISUALLY IMPAIRED ASSISTANCE
Abstract:
Device, system, and method of assistance for visually impaired users. The system comprises a plurality of video cameras, often head mounted, computer processors and associated support devices and algorithms configured for computer vision, and a user worn haptic band comprising a plurality (two or more) of distantly spaced haptic transducers. This haptic band is worn such that user's hands are free for other tasks. The system uses its video camera, depth processing algorithms, and object recognition algorithms (hardware and/or software based) to identify a limited number of navigationally important objects. The spatial locations of each object deemed important is output to the user by varying output to the haptic transducers accordingly. The system is configured to identify and report objects as generic objects, identified objects, and potential obstacle objects. The system can also optionally provide audio information or tactile graphics display information pertaining to these objects as well.
