Реферат: Input devices for use with radiotelephones, and other electronic devices, recognize and display handwritten alphanumeric characters on a display. A plurality of adjacent touch switches are arranged in an array beneath an exposed touch pad. Each touch switch in the array produces, in response to user activation of an area of the touch pad during a handwriting stroke, a respective analog voltage signal. An analog/digital converter receives and converts a sequence of analog voltage signals produced by a user activating one or more of the touch switches during a handwriting stroke into a sequence of digital values. A processor, working in conjunction with a handwriting recognition algorithm, processes the sequence of digital values, recognizes the alphanumeric characters that corresponds to the handwriting strokes of the user, and then displays the recognized alphanumeric characters within the display.
