An apparatus and method for providing a three-dimensional (3D) input interface is provided. The apparatus includes multiple light emitters to emit an optical signal having a determined characteristic to form a 3D input recognition space; a light receiver to receive the optical signal reflected from an object, which is located in the 3D input recognition space, and to obtain luminous energy information of the optical signal; and a control unit to extract a coordinate of the object based on the luminous energy information, and to control an operation of the apparatus based on the coordinate of the object.
