ABSTRACT:
A disk shaped element has a plurality of tactile sensed position indicators arranged along its' circumference. Each position indicator consists of a straight bar terminated at one end with a rod having a diameter greater than the thickness of the corresponding bar. Each bar extends outwardly from the circumference of the disk, and each rod extends outwardly from the circumference a distance greater than the corresponding bar. Each position indicator on the dial is oriented analogous to an hour hand position on a clock, with the rod providing a reference for the base of the hand.
