Patent ID: 7196691

Claim:
A method for receiving data into a computer, the method comprising: associating multiple alphanumeric keys on a keyboard with data; detecting a pause during typing; detecting the simultaneous pressing of the multiple alphanumeric keys after the pause by; determining if a first of the multiple alphanumeric keys is part of a standard pair; determining if a second of the multiple alphanumeric keys is part of a standard pair; determine if the second of the multiple alphanumeric keys is depressed within a pre-determined period of time of the first of the multiple alphanumeric keys; determine if the first and second alphanumeric keys are both depressed for a period of time which is dependent upon the period of time elapsed between the first and second keypresses; and if the first and second alphanumeric keys have been depressed simultaneously then use the associated data instead of the multiple alphanumeric keys simultaneously pressed as input data.
