  • Method for entering characters on a keyboard and a keyboard
    Patent number: 8081092
    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.
