摘要： An orientation system for a visually impaired user which includes a base station and a handset; said base station is attached close to an item that the user wishes to orientate themselves to; the base station is configured to emit a beam which is unable to penetrate solid objects and which has a centreline; the handset is configured to detect the beam and generate an output which the user can use to determine the edges of the beam and thus orientate approximately with the centreline.
