Method and apparatus for interacting with television screen

摘要

A method of interacting with a television screen using a remote control having a viewing screen. The method includes the following: (1) displaying a boundary-identifier, on the viewing screen that is substantially transparent, to specify the boundary of an effective input-area; (2) detecting one or more positions being touched on the viewing screen after the boundary-identifier is displayed on the viewing screen; and (3) determining at least one mapped position on the television screen, wherein the at least one mapped position is mapped from a position among the one or more touching positions on the viewing screen of the remote control under a mapping operative to map one of an irregular quadrilateral and a trapezoid to a rectangular. The method also includes determining the effective input-area, which includes analyzing the image of the television screen obtained with a camera on the remote control.
