Abstract:
A device having a cane (10) to aid the orientation of blind people, comprising:a. detection means (20, 22, 38) which, by emitting and receiving laser beams, detect objects in a two-dimensional detection area located in a detection plane containing the cane (10) and comprise: i. beam deflection means (24) for deflecting the emitted laser beams (28) in this detection area, and ii. receiving means (22) which respond to the emitted laser beams after they have been reflected or scattered by an object located in this detection area, b. indicating means (40) which i. indicate the presence of an object in the thus generated two dimensional detection area (34) by a first information, and ii. indicate the absence of an object in the thus generated two-dimensional detection area (34) by a second information.
