The user is then able to know, intuitively, the position of the numeric key and be able to tap it without looking at it. Because the user holds the phone upside down and the keys are not an exact match to the typical keyboard, a third party cannot derive the code by watching the user enter it.

The novel design of the keyboard presents each key (e.g., the standard 10 keys, or possibly only four or six of the 10) at approximately half the width of the phone and 1/N/2 the height of the phone.
