After investigating several options, a Vancouver volunteer designed a
modified laser prototype to test for the school board. The laser beam's
intensity was decreased by using a filter, thereby increasing the safety
factor for the other students and staff. The adapted laser point was
inserted into an aluminum tube that attached to the child's headband.
The modified pointer was approved by the school board and the design
was consequently used as a model for other pointers used in the school
system.
