The handicapped find many difficulties
that complicate their life and prevent them from living a
normal social life. In order to ease their embarrassment and
improve in some way the quality of their life, the "laser
stick with rechargeable battery" has been created. It consists
of a special stick for blinds inside which an electronic device
is inserted. This device is formed by: a rechargeable battery,
an integrated circuit producing a little laser ray, and a
tiny computer that analyses and sends to a buzzer the encoded
signal. In practice, as the laser ray approaches the objects,
it indicates to the tiny computer their distance; consequently,
the computer emits a sound of different frequency that the
blind will learn to identify in a while. The more the obstacle
is next, the more the sound is sharp and vice versa. In order
to prevent the stick from becoming an annoyance in the long
run, a switch for turning on and off the device at pleasure,
has been inserted on its handle, so that the blind will be
free to use it whenever he/she needs (e.g. in unknown places)
and deactivate it in places he/she well knows. An aspect not
to be overlooked is the psychological effect of the "independence"
deriving from the constant use of this futuristic device.
