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 items
being accessed. It also eliminates the unsightly
barrier imposed by forehead pointers because it does not
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 the 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.
