<p>A telephone keypad (10) emulation system for emulating data entry of a telephone keypad (10). The telephone keypad emulation system includes a first selector device (30) and a second selector device (32). The first selector device (30) has at least nine position settings (12 ) generally arranged in three rows (34,36,38) and three columns (40,42,44). The second selector device (32) includes a selection actuator adapted to be actuated by a user. The second selector device (32) is spaced from the first selector device (30). In a first mode of operation, a middle one of the position settings of the first selector device (30) has a number "5" as a selectable value. The selectable value of the position settings of the first selector device (30) is only selected when the selection actuator of the second selector device (32) is actuated by the user while the first selector device (30) is at that position setting.</p> |
