Laser
pointers may be used in lectures to point to projected information.
They can also be used by someone to point to items on a
communication board or wall chart. The type of laser pointers used
in lectures can be purchased very inexpensively. The Laser Pointer
from GEWA, however is specifically designed to be used as an
accessing tool for communication.
The DIFFERENCE is
the safety factor. Regular laser pointers can cause damage to the
retina if they are projected directly into someone's eye. They are
graded as safe for public use as they project a visible light that
cannot harm the skin. The GEWA Laser Pointer has an altered
output such that in order to damage the retina, the laser beam must
be held absolutely still, fixed on one specific spot, and not moved
for approximately 4 seconds — which is virtually impossible. This
means that the GEWA Laser Pointer has a security time 16 times
greater than the regular type of laser pointer used in lectures.
This is significant when the person using the laser pointer is
wearing it on his or her head and pointing to a communication board
or a wall chart. When eye contact is made with a communication
partner, the laser pointer may be inadvertently directed into the
partner's eyes.
The GEWA Laser Pointer has been used successfully in a hospital in
Melbourne, Australia with patients in bed who use a communication
charts mounted on the wall. Although these particular patients had a
diagnosis of motor neuron disease (ALS), this application may be
relevant to others regardless of the diagnosis.
