1. A method of inputting a three-dimensional (3D) location using a touch surface interface for generating a control signal, the method comprising:
- determining whether the control signal is a 3D movement signal for moving a pointer existing at a point in a two-dimensional (2D) coordinate plane into a 3D space; and
based on a result of the determining, selectively moving the pointer to a point in the 3D space existing in a direction perpendicular to the 2D coordinate plane, according to the control signal,wherein the determining comprises determining the control signal is the 3D movement signal, when the control signal corresponds to a movement of a user following a predetermined shape in a 2D coordinate plane on the touch surface interface.

Abstract
Provided are a method and apparatus for inputting a three-dimensional (3D) location. The method determines whether a control signal for moving a pointer existing at a point in a two-dimensional (2D) coordinate plane is a 3D movement signal for moving the pointer into a 3D space; and based on a result of the determination, the method selectively moves the pointer to a point in the 3D space existing in a direction perpendicular to the 2D coordinate plane, according to the control signal.

13. A three-dimensional (3D) location input apparatus for inputting a 3D location using a touch surface, the 3D location input apparatus comprising:
-
a determination unit which determines whether a control signal for moving a pointer existing at a point in a two-dimensional (2D) coordinate plane is a 3D movement signal for moving the pointer into a 3D space; and a pointer movement unit, based on a result of the determining, which selectively moves the pointer to a point in the 3D space existing in a direction perpendicular to the 2D coordinate plane, according to the control signal, wherein the determination unit comprises a first determination unit which determines the control signal is the 3D movement signal, when the control signal corresponds to a movement of a user following a predetermined shape in a 2D coordinate plane on the touch surface. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
