Patent ID: 8854321

Claim:
A method comprising: detecting, by a data entry system, an initialization action performed by a first extremity of a user and a second extremity of the user with respect to a touch screen associated with a computing device, the initialization action comprising a touching of a first arbitrary location on the touch screen by the first extremity of the user and a touching of a second arbitrary location on the touch screen by the second extremity of the user; designating, by the data entry system in response to the initialization action, the first arbitrary location as a first reference position associated with the first extremity and the second arbitrary location as a second reference position associated with the second extremity; detecting, by the data entry system, one or more tapping actions performed on the touch screen by one or more human input elements included in a plurality of human input elements that are a part of the first and second extremities; determining, by the data entry system, a relative position on the touch screen of each of the one or more tapping actions with respect to the first and second reference positions; and identifying, by the data entry system, one or more data entry commands associated with the one or more tapping actions based on the relative position of each of the one or more tapping actions with respect to the first and second reference positions.
