A data entry pad arrangement includes twenty-six letters of the Roman alphabet arranged in a matrix including six rows of three to six letters per row. Ideally, no two adjacent letters in a row of the matrix are in alphabetical order. A method for designing a data-entry interface layout including letters of the Roman alphabet thereon involves the transposition of the letters of the Roman alphabet on a three-row QWERTY keyboard into six rows, wherein a letter (optimally every other letter) within a first, second, or third row of said three-row QWERTY keyboard is placed in an additional row substantially below an adjacent letter of said first, second, or third row.
