## Abstract

A data entry interface for use with an electronic device (200) includes a first row of keys that have a first group of letters (1A, 2A, 3A, 4A, and 5A) and a second group of letters (1B, 2B, 3B, 4B, and 5B) that are horizontally offset from the first group of letters. A second row of keys are positioned below the first row of keys and have a third group of letters (6A, 7A, 8A, 9A, 10A) and fourth group of letters (6B, 7B, 8B, 9B, 10B) such that the third group of letters are vertically aligned with the first group of letters and the second group of letters are vertically aligned with the second group of letters. A third row of keys are positioned below the second row of keys having a fifth group of letters (11A, 12A, 13A, 14A, 15A) and sixth group of letters (11B, 12B, 13B, 14B, 15B) such that the fifth group of letters are vertically aligned with the first group of letters and third group of letters and the sixth group of letters are vertically aligned with the second group of letters and fourth group of letters.
