Abstract: A processor-implemented method for collecting a sequence of security code characters includes: detecting a trajectory through a region proximate the device followed by an instrument; responsive to the trajectory, identifying one of a collection of defined gestures; and interpreting the identified gesture as the portion of the security code.

Abstract: The subject disclosure is directed towards a graphical or printed keyboard having keys removed, in which the removed keys are those made redundant by gesture input. For example, a graphical or printed keyboard may be the same overall size and have the same key sizes as other graphical or printed keyboards with no numeric keys, yet via the removed keys may fit numeric and alphabetic keys into the same footprint. Also described is having three or more characters per key, with a tap corresponding to one character, and different gestures on the key differentiating among the other characters.
