Abstract

An electronic device includes a touch-sensitive display screen including an array of electromagnetic radiation detectors. The array of electromagnetic radiation detectors is configured to generate an image signal that represents an image of a user input object that is closely spaced to the display, and to generate a touch signal in response to the display screen being touched by the user input object. The electronic device further includes a controller circuit that is configured to display a plurality of keys forming a keyboard and to display characters on the keys. The controller identifies from the image signal a size and/or an angular orientation of the user input object relative to the display screen. The controller identifies a user's selection among characters indicated on the keyboard keys in response to the identified size and/or the angular orientation of the user input object and in response to the touch signal, and outputs character data corresponding to the identified user selected character.
