- W811334551 abstract "This paper describes how visually challenged persons face constraints in independent mobility and navigation. White cane can only be used to detect obstacles up to knee-level within a range of only 2-3 feet. Further, the visually challenged are unable to access the bus transport system without sighted assistance as they cannot read the route number and are unsure about the physical location of the bus and its entry/exit door. This project is aimed at developing two systems to address these problems: (i) Cane mounted knee-above obstacle detection and warning system using ultrasound beam to enhance the horizontal and vertical detection range, and (ii) User-triggered bus identification and homing system using radio-frequency (RF) communication." @default.
