<p>An apparatus (10) and method is provided for inputting information into an electronic device (90) using the primary and first and second ancillary digits of the operator's hand. The apparatus (10) includes an interface surface (12) having a selector pad (20) divided into a plurality of selector pad switches (22). The selector pad switches (22) are arranged according to a 3 x 3 array for activation by the operator's index finger. Located laterally and below the selector pad (20) are two address switches (33), (35) capable of being selected by the middle finger and thumb of the user's hand. Using the two address switches (33), (35), each selector pad switch (22) may be assigned up to four possible switch addresses. A microprocessor assigns a code element taken from a programmable code table (65) to each switch address. By using the digits to select the various combinations of switches, the operator is able to input information into an electronic device (90) designed to receive such information.</p> |
