Claim:
1. A method of controlling an object, the method comprising: detecting a position of at least one finger of a user, the at least one finger present in a 3-dimensional (3D) sensing area, and a number of the at least one finger present in the 3D sensing area, the 3D sensing area comprising a volume up to a predetermined height above a sensing panel of the sensing module, wherein the sensing panel comprises upper electrodes and lower electrodes to detect the position and the number of the at least one finger present in the 3D sensing area; generating motion information regarding motions of the at least one finger based on the position and the number of the at least one finger; and controlling at least one of a pointer and an object being displayed based on the motion information, wherein the upper electrodes and the lower electrodes are arranged in a form of a grid, wherein the detecting of the position and the number of the at least one finger comprises: calculating curvatures of a plurality of portions included in the at least one finger in the 3D sensing area, wherein at least two portions of the plurality of portions correspond to different joints of the same finger; detecting a position and a number of at least one portion, from among the plurality of portions, having a curvature greater than a reference curvature; extracting at least one intersection between the at least one portion and vertices of a polygon connecting outermost vertices of a hand of the user; and determining at least one finger tip of the user based on the at least one intersection.
