Abstract: The present invention relates to an image display apparatus and method for displaying a three-dimensional (3D) image capable of interacting with a user, and provides a 3D image display apparatus and method that may interact with a user by reproducing a 3D image, generated by a conventional volume display apparatus, at a position different from a position at which the 3D image is generated, and by modifying and playing the reproduced 3D image based on a motion of the user. Also, the present invention enables the user to realistically interact with the 3D image by stimulating tactile sensation of the user through ultrasound.

Abstract: Provided are a 3D display device and a method of manufacturing the same. The 3D display device includes a curve-shaped display panel displaying an image, and a curve-shaped lenticular lens disposed in front of or behind the display panel. A left-eye image displayed by the display panel is presented to a user's left eye through the lenticular lens, and a right-eye image displayed by the display panel is presented to a user's left eye through the lenticular lens.

Abstract: A mobile terminal and a method of providing a video call using the same are disclosed. More particularly, a mobile terminal capable of supporting a video call while ensuring user's privacy by mounting a three-dimensional depth camera and a two-dimensional camera in the mobile terminal and a method of providing a video call using the same are disclosed. The mobile terminal of the present invention includes a 2D camera 200 capturing a 2D video and a 3D depth camera 210 capturing a 3D depth video; an individual image separation module 112 extracting boundary information between a user and a background by using depth information regarding a video captured by the 3D depth camera 210; a composite video generation module 114 separating the user video from the video captured by the 2D camera 200 by using the extracted boundary information and composing the separated user video and the set background video.

Abstract: The present invention relates to an apparatus for touching a projection of a 3D image on an infrared screen using a single-infrared camera, and more specifically to an apparatus for touching a projection of a 3D image, which projects an image in a free space; recognizes a position touched by a user on the projected image and thus can process an order from a user on the basis of the recognized touched position. The present invention can provide tangible and interactive user interfaces to users. In particular, it is possible to implement various UIs (User Interface), in comparison to an apparatus for touching a projection of a 2D image of the related art, by using the Z-axial coordinate on the infrared screen as the information on depth.

Abstract: The present disclosure relates to a spatial touch apparatus using a single infrared camera. More particularly, it relates to a spatial touch apparatus to implement a virtual touch screen in a free space by using an infrared light emitting diode (LED) array and a single infrared camera and to calculate X-axis and Z-axis coordinates of the infrared screen touched by a user indication object. Therefore, the present invention will provide tangible and interactive user interfaces to users and can implement more various user interfaces (UI) than a conventional 2D touch apparatus.

Abstract: A table type 3D video display device and a table type interactive user interface are disclosed. More particularly, a method for providing services such as games, education, shopping, virtual experience, or the like, of a 3D type is disclosed. The interactive 3D system of the present invention includes a table type 3D display module 210 displaying 3D videos; a spatial touch recognition module 200 monitoring a position of user's fingers interacting with the displayed 3D videos; and an interaction computing module 230 controlling the 3D display module and the spatial touch recognition module 200.

Abstract: Disclosed herein is an infrared screen-type space touch apparatus. The infrared screen-type space touch apparatus includes an infrared LED array provided with infrared LEDs arranged in a line, and configured to emit infrared rays and generate an infrared screen in a space. An infrared camera is installed to allow a lens thereof to face the infrared screen. A space touch sensor module senses a location touched by a user pointing means on the infrared screen from a gray scale image captured by the infrared camera. Further, the infrared screen-type space touch apparatus may further include a pulse generation unit configured to periodically generate a pulse signal, and an LED driver unit coupled to the pulse generation unit and configured to supply pulsed DC power to the infrared LED array.
