Claim:
A smart phone having a dual touch pad interface comprising: a graphical user interface; a first touch pad, which is operably connected to the smart phone, that has a plurality of first touch pad sensors arranged in at least one first touch pad shaped layout such that each of the plurality of first touch pad sensors corresponds to a letter from a first subset of a set of letters in an alphabet; a second touch pad, which is operably connected to the smart phone, that has a plurality of second touch pad sensors arranged in at least one second touch pad shaped layout such that each of the plurality of second touch pad sensors corresponds to a letter from a second subset of the set of letters in the alphabet, the second subset including remaining letters in the alphabet that are distinct from that of the first subset; and a processor that (i) receives sensor data from the first touch pad and the second touch pad, (ii) determines a last character in the sensor data received prior to the user removing a digit from the first touch pad or the second touch pad, and (iii) outputs the last character to the graphical user interface.
