Abstract:
There is provided a projector including a projection control unit which controls a projection of a background window and computes location information of at least one projection window projected on the background window, a performance sensing unit which senses an object performance on the background window and the at least one projection window, a communication unit which communicates with at least one other projector different from the projector, and an information control unit which controls an operation of each of the at least one other projector, the operation corresponding to the object performance.
Abstract:
A method and apparatus for performing an automatic wireless connection with a second digital device by a first digital device is provided. The method includes acquiring, by the first input device, random information used for the wireless connection; checking a status of a Wireless Local Area Network (WLAN); storing the checked status; setting the WLAN to an Ad-hoc mode; setting a Service Set Identifier (SSID) of the WLAN using the random information; setting a security key of the WLAN using the random information; and setting an Internet Protocol (IP) address of the WLAN using the random information.
Abstract:
A method of sharing contents among devices, the method includes a first device and a second device performing a time synchronization, the first device receiving, from a user, a time stamp with respect to contents being replayed by the second device, the first device transmitting the time stamp to the second device, the second device transmitting a contents list corresponding to the time stamp to the first device, the first device requesting the second device for contents selected by the user from among the contents list, and the second device providing the requested contents to the first device.

Abstract:
A projector control system includes a location measurement unit which measures location information of a projector; a projection information unit which generates projection information using the location information; a communication unit which transmits the projection information to the projector; and an image control unit which controls the projector to project an image according to the projection information.
Abstract:
A method for printing a document of a mobile terminal without a separate printer setup is provided. The method includes performing a wireless auto-connection between a mobile terminal and a printer located near the mobile terminal, and when the mobile terminal transmits a document to be printed to the printer, the printer finds a computer capable of outputting the document, transmits the document to the computer, and prints the document in response to a print instruction received from the computer. Accordingly, a user can print various documents stored in the mobile terminal wherever a printer is located, even without information of the printer.
Abstract:
A network device driver includes a fetching/hooking module to fetch/hook hardware data and/or a hardware event of the communication terminal; a packet assembly module to packetize the hardware data and/or the hardware event; a packet release module to recover the packetized hardware data and/or the hardware event, which are/is received from another terminal connected with the communication terminal via a wired/wireless communication network; and a transmission module to receive/transmit the packetized hardware data and/or the hardware event from/to another communication terminal.
Abstract:
A method and system are provided for automatic wireless connection to a digital device in a portable terminal, wherein information about the portable terminal is acquired. The information about the portable terminal is commonly used for automatic wireless connection to the digital device. A state of a Wireless Local Area Network (WLAN) is checked and activated, and the WLAN is set to an Ad-hoc mode. A Service Set Identifier (SSID) of the WLAN is set using the acquired portable terminal information, a security key of the WLAN is set using the acquired portable terminal information, and an Internet Protocol (IP) address of the WLAN is automatically set using the acquired portable terminal information.
Abstract:
A presentation control system and method are provided, in which a first terminal is connected to a second terminal to control displaying of a presentation file stored in the second terminal. The first terminal controls execution of the presentation file in the second terminal, controls execution of switching between slide pages included in the presentation file in the second terminal, and controls closing of the presentation file in the second terminal.
Abstract:
A recognition control method among devices, the recognition control method includes receiving a second device recognition signal via a wireless signal module of a first device from a wireless signal module of a second device, and recognizing that the second device is located in a direction from the first device through the second device recognition signal. With respect to the second device, the method includes receiving a first device recognition signal via the wireless signal module of the second device from the wireless signal module of the first device, and recognizing that the first device is located in a direction from the second device through the first device recognition signal.
