KEY ARRANGEMENT FOR A KEYBOARD

摘要

Methods and systems for key arrangements including a plurality of keys arranged in a plurality of rows and a plurality of columns. At least one of the plurality of keys has a predetermined key width determined by dividing a face width of a device by a number of the plurality of columns. Each row of the plurality of rows has a first key located at a first end, a second key located at a second end, at least two interior keys located between the first and second keys. The respective widths of the first key and the second key are determined by subtracting a predetermined amount from the predetermined key width such that the respective widths of the first and second keys are smaller than interior key widths of the at least two interior keys.
