摘要
Provided are a stereoscopic image display unit having a 3D information input device and a 3D stereoscopic image display method using the 3D information input device. The 3D information input device receives a synchronization signal used for a conventional stereoscopic image display unit and generates an ultrasonic signal. The stereoscopic image display unit receives the ultrasonic signal through the ultrasonic wave reception units installed at a plurality of areas and measured a distance between the 3D information input device and each of the ultrasonic wave reception units by using a time difference between a generation time of the synchronization signal and a reception time of the ultrasonic signal and measures a position of the 3D information input device in a 3D real space by using the distances. The measured position of the 3D information input device in the 3D real space is converted into a coordinate in the 3D stereoscopic image space. A position of the 3D information input device functioning as a mouse or a remote controller is stereoscopically displayed on the 3D stereoscopic image, so that click information or menu selection information can be input. A synchronization signal logic used for a conventional stereoscopic image display unit is employed, so that it is possible to embody a 3D remote controller or a 3D mouse without an increase in cost caused by addition of the configuration.
