Abstract

See full text

Methods, systems, and products estimate distances to aid a visually impaired user of a mobile device. As the user carries the mobile device, a camera in the mobile device captures images of a walking cane. The images of the walking cane are analyzed to infer a distance between a tip of the walking cane and the mobile device. The distance may then used by navigational tools to aid the visually impaired user.
