Safe Laser Pointer

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 Safe Laser Pointer is useful for both short and long distances in that its "dot" is viewable easily at 25 feet (7m). This pointer has been adapted and approved specifically for people with disabilities. Operating time is approximately 8 hours on a charge. Rechargeable NiMH battery, charger, and attachments are included.

The laser can be turned on and off by the built-in pushbutton switch or an external switch.

The GEWA Laser Pointer has been used successfully in a hospital in Melbourne, Australia with patients in bed who use a communication chart 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.
