METHOD FOR CORRECTING POSITION OF CONTROLLER INTO RECOGNIZABLE RANGE OF MULTIMEDIA DEVICE AND THE MULTIMEDIA DEVICE THEREFOR AND TARGET TRACKING DEVICE

摘要

The present invention provides a method which enables a subject to be accurately positioned in the recognizable area of a multimedia device. To this end, the present invention includes the following steps of: receiving an image through a target tracking unit which is installed in the multimedia device; detecting and tracking a recognition object from the received image; searching a controller which has an acceleration sensor if the recognition object is not detected in the received image; obtaining acceleration information from the searched controller and determining where the recognition object is positioned outside the recognizable area of the multimedia device; and outputting derived information in order to enter the recognizable area. Therefore, a user who deviates from the recognizable area is able to move in order to be accurately positioned within the recognizable area.
