Abstract

A hand held telephone having twelve push buttons arranged in a clock face orientation around a centrally located swivel button. The push buttons are arranged so that the number one button is arranged at approximately a one o'clock orientation, the number two button is set approximately at a two o'clock orientation and so on through the number nine button at an approximate nine o'clock orientation. A zero button is positioned at the approximate 10 o'clock orientation and "*" (star) button is positioned at an approximate eleven o'clock orientation and the "#" (pound) button is positioned at an approximate twelve o'clock orientation. By arranging the buttons normally found on a telephone in a clock face orientation, it is possible to move the forefinger of an individual to the approximate clock setting so as to key actuate an appropriate number. This can be accomplished without visually focusing on the clock face. In addition, upon actuation of the numbered buttons, a synthesized voice indication is made of the button depressed so as to confirm the correct actuation. The centrally located swivel button includes a pivot pin by which the tip of the forefinger of an individual can guide the swivel button clockwise or counter-clockwise until reaching a desired approximate clock hour orientation. Then upon tilting depression of the pivot pin, if properly positioned, the pin will provide the feel of the pin engaging a detent and simultaneously will complete an electrical circuit for synthesized voice announcement of a particular dial number of the telephone. The synthesized voice confirms the correct positioning of the pivot pin so as to dial a predetermined number.
