AD-1 Standard Pointer*
This head-worn pointer represents a significant design advancement in providing efficient pointing from a psychologically and cosmetically sound perspective: the chin. Unlike forehead protrusion pointers, using an "out from the chin" device more realistically places the pointer in proximity to the item(s) being accessed. It also eliminates the unsightly barrier imposed by forehead pointers because it doesn't interrupt either the wearer's field of vision or the full view of the wearer's face. This unit is fully adjustable; capable of being individually fitted to head sizes from 20-25 inches in circumferences.

AD-2 "Tiny Tot" Pointer

This unit has all the characteristics of the AD-1 above, but is specially sized for small heads from 17-20 inches in circumference. The headband has a rear strap adjustment and the yoke assembly is sized for these smaller heads.

AD-3 Standard Pointer (w/Rear Strap Closure)

This model is a "gap filler" between the AD-1 and AD-2. The yoke assembly is standard size, but the rear knob adjustment portion of the AD-1 head band has been replaced with a hook and loop strap closure. This is particularly helpful when the wearer is seated against any headrest mechanism where the AD-1 knob would continuously abrade the rest and cause discomfort. Also, it accommodates adult wearers with slightly smaller than average head sizes, for whom the overall yoke size reduction of the AD-2 is inappropriate.
