Abstract: A method of providing a user interface, including receiving a motion signal from a pointing device including a pointing function for moving a pointer, while the pointer is not generated on a display screen; generating the pointer when it is determined, based on the received motion signal, that the pointing device is moved in a predetermined form; displaying the generated pointer on the display screen; and providing a menu on at least one corner of the display screen.

Abstract: A method for displaying widget windows is provided, including generating a widget display screen including at least one widget window, determining if a display area of the at least one widget window satisfies a preset threshold condition, and adding a new widget display screen including a new widget window if the threshold condition is satisfied. Accordingly, services can be provided through widget windows without preventing the viewer from viewing the TV, thereby enhancing user convenience.

Abstract: A method and apparatus for performing an image forming job by maintaining a cover, which covers a scan area and has adjustable transparency, in a transparent state until a job for acquiring image data of a scan object starts in an image forming apparatus. If the job for acquiring the image data of the scan object positioned in the scan area starts, the image forming apparatus converts the cover into an opaque state and acquires the image data of the scan object. If the job for acquiring the image data of the scan object is ended, the image forming apparatus reconverts the cover into a transparent state. Therefore, efficiency of a job for acquiring image data of a scan object is improved.

Abstract: A mobile device and a method performed by the mobile device for receiving a service from a service providing apparatus are provided.

Abstract: A method and apparatus for providing a service in a service providing device are provided. The method includes receiving, from a terminal, information about a wireless transmitter/receiver whose vicinity the terminal is located within; determining a differentiated service to be provided to the terminal according to the received information about the wireless transmitter/receiver; and providing the determined differentiated service to the terminal.

Abstract: The present disclosure relates to a spacer structure that is configured to be disposed between a pair of electrodes in a capacitive deionization apparatus so as to provide a space for flowing a fluid therethrough. The spacer structure includes a copolymer prepared by copolymerizing a mixture of a polyurethane backbone including a carboxyl group or a sulfonic acid group, an ion conductive monomer including a carboxyl group and a cation exchange group, and a second polymer including a functional group that reacts with the carboxyl group or sulfonic acid group and forms a cross-linking bond with the polyurethane backbone.

Abstract: A capacitive deionization apparatus may include at least one pair of porous electrodes and a spacer structure disposed between the at least one pair of electrodes. The at least one pair of porous electrodes may include an electrode material having a surface area for the electrostatic adsorption of feed ions. The spacer structure may include an electrically-insulating material with an ion exchange group on the surface thereof. The spacer structure provides a path for flowing a fluid therethrough.

Abstract: A method of providing information related to an object is provided. The method includes sensing a gesture related to the object located in a certain area via a first device, obtaining content related to the object according to the sensed gesture, and transmitting the obtained content to a second device that is connected with the first device in a network, wherein the content is output via the second device.

Abstract: A system and a method for providing an image related to an image displayed on a device are provided. A method of providing a second image that is related to a first image displayed on a device includes receiving a request for the second image that is related to the first image displayed on a screen of the device, from a server, and providing the second image to the server in response to the request, wherein the second image is projected onto a plate on which the device is disposed, by a projection apparatus connected to the server, and wherein the first image displayed on the screen of the device is a part of a whole image related to the first image displayed on the screen of the device, and wherein the second image includes another part of the whole image.

Abstract: A method of providing a transaction related service is provided. The method includes receiving first payment method information corresponding to a store from a first device; comparing the first payment method information and second payment method information available for a user; and recommending the second payment method based on a result of the comparison.

Abstract: A method of providing a user interface, including receiving a motion signal from a pointing device including a pointing function for moving a pointer, while the pointer is not generated on a display screen; generating the pointer when it is determined, based on the received motion signal, that the pointing device is moved in a predetermined form; displaying the generated pointer on the display screen; and providing a menu on at least one corner of the display screen.

Abstract: A method for displaying widget windows is provided, including generating a widget display screen including at least one widget window, determining if a display area of the at least one widget window satisfies a preset threshold condition, and adding a new widget display screen including a new widget window if the threshold condition is satisfied. Accordingly, services can be provided through widget windows without preventing the viewer from viewing the TV, thereby enhancing user convenience.

Abstract: A display apparatus for displaying a widget window and method thereof are provided. The display apparatus includes a generating unit which generates at least one widget window, a display unit which displays the least one widget window generated by the generating unit on a screen, and a control unit which changes a display pattern of the widget window, if a preset event occurs. Accordingly, the display patterns of widget windows are changed according to a user's preference, making it possible to increase the user's convenience.
