Abstract: In one aspect, a method for entering characters on a keyboard comprising a first character key, e.g. the space bar, to which a first character, e.g. a blank space is assigned and a second key, to which a second character, e.g. q and a third character, e.g. @ are assigned is provided. Accordingly, when the first character key is depressed, a timer is started. Before the time has run out and whilst the first character key is depressed, the second key can be pressed to obtain the third character. Before the time has run out, and before the second key is depressed, if the first character key is released, the first character is obtained. Once the timer has run out and the first character key has been released, if the second key is depressed, the second character is obtained.

Abstract: A time-enhanced input device driver for a data processing system is capable of generating time-enhanced output in response to input signals. The input device driver receives a first input-event signal followed by a second input-event signal. In response to the second input-event signal, the input device driver generates a character code and an associated time-span code. The time-span code reflects the amount of time that separated the first input-event signal from the second. In an illustrative embodiment, the first and second input-event signals may comprise a key-down signal from a particular key on a keyboard and a key-up signal from that key respectively, in which case the generated character code would correspond to that key.

Abstract: A technique to switch between upper and lowercase alphabetic characters in a wireless communication device measures the period of time in which a numeric key is held in the depressed position by the user. If a numeric key is pressed by the user for a period of time less than a predetermined threshold time, the selected alphabetic character is displayed in a default character case. If the selected numeric key is held in the depressed position for a period of time exceeding the predetermined threshold period, the character case is altered and the altered alphabetic character is displayed for the user. The user selects the desired alphabetic character by activating a selected numeric key one or more times corresponding to the desired alphabetic letter. If the selected numeric key is held in the depressed position for a period of time exceeding the threshold period during any of the button depressions, the system automatically changes to the altered alphabetic character case.
