WHITE STICK FOR BLIND PERSONS

摘要

The invention relates to a white stick with a transmitter for emitting directed signals, a receiver for receiving signals which are reflected by an object and with display means for converting received signals into an indication which is perceptible by the user of the white stick. The display means comprise an at least partially ring-shaped element extending around the white stick and which through a motor is rotatable around an axis which substantially coincides with the centerline of the white stick, wherein the plane in which said ring-shaped element is positioned encloses an angle with said axis differing from 90 DEG . It is possible that the ring-shaped element is at least partially housed in a recess provided in the surface in the white stick.
