Keyboard input control method and system

摘要

A method for processing input from a keyboard of a hand-held computing device includes receiving a plurality of key input events and, from the plurality of key input events, determining whether there is a double selection event corresponding to a specified key from the keyboard. Further, the method includes, when it is determined that there is the double selection event corresponding to the specified key, determining a key selection offset between a first and second key selection action of the double selection. The method also includes deciding whether the key selection offset is substantially equal to or greater than a predetermined threshold and, when it is decided that the key selection offset is substantially equal to or greater than the predetermined threshold, using at least a first key as key input of the double selection event. The first key and the specified key are different.

1. A method for processing input from a keyboard of a hand-held computing device, comprising:
receiving a plurality of key input events; determining whether the key input events include a double selection event, wherein the double selection event includes a first key selection action of a specified key at a first time instance and a second key selection action of the specified key at a second, different time instance within a predetermined time period; determining a key selection offset between the first key selection action and the second key selection action in the double selection event, wherein the key selection offset is a distance between a first point on the specified key associated with the first key selection action at the first time instance and a second point on the specified key associated with the second key selection action at the second, different time instance, the key selection offset defining a key input of the double selection event; determining whether the key selection offset is less than a predetermined threshold; and using at least a character associated with a first key, different from the character associated with the specified key, as the key input of the double selection event based on the determination that the key selection offset is less than a predetermined threshold.
