Abstract: Disclosed are a portable apparatus and a method for sharing content thereof, in which the method of sharing contents in a portable apparatus includes receiving user interaction with a document targeted for photographing through a camera of the portable apparatus; and sharing a content corresponding to the document with at least one remote device so as to correspond to the user interaction with the document. With this, the user interaction with the contents of the portable apparatus input through the camera and the document targeted for photographing is shared with the remote device, thereby efficiently supporting education focused on students.

Abstract: A display apparatus includes: a display; a processor configured to process a content image to be displayed on the display; a storage configured to store a database where control commands for controlling operations of the processor corresponding to a plurality of pieces of the rotation information and a plurality of pieces of the touch information are designated according to kinds of contents; and a controller configured to determine a kind of content corresponding to the content image being displayed on the display in response to receiving at least one from among rotation information corresponding to a user's rotating operation and touch information corresponding to a user's touching operation, from an input device, and configured to control the processor to execute a control command corresponding to the received rotation information or the received touch information from the database based on the determined kind of content.

Abstract: A method of displaying information when an electronic apparatus is booted is provided. The method includes storing specific information, the specific information being monitored and collected from data created when the electronic apparatus operates, in an information file, and executing the information file storing the specific information during booting of the electronic apparatus and displaying the specific information.

Abstract: A screen displaying method in a portable apparatus includes displaying a personal screen of an application executed by the portable apparatus in response to input user identification information; detecting a touch on the personal screen; and controlling the personal screen in response to the touch to display a second screen, wherein the second screen includes at least a portion of a common screen which is a screen of an external device connectable through a network.

Abstract: A terminal device and a data transceiving method are provided. The terminal device includes a sensing unit which senses a momentum of the terminal device, an interface unit which receives a momentum from at least one external device, and a control unit which performs one of a data receiving operation, a data transmitting operation, and a data transceiving operation with the at least one external device depending on a comparison value obtained from a comparison of the sensed momentum with the received momentum to allow two devices to exchange data more easily.

Abstract: A method for providing a UI and a portable apparatus applying the same are provided. The method for providing the UI of the portable apparatus includes determining whether motion of shaking the portable apparatus a predetermined number of times is input or not using a sensor included in the portable apparatus, and, if the motion of shaking the portable apparatus the predetermined number of times is input, providing haptic feedback according to a number of pieces of information displayed on a notice window of the portable apparatus. Accordingly, if a predetermined event occurs, haptic feedback corresponding to the predetermined event is provided, so that the user can identify the event without seeing a display.

Abstract: A method and device for providing information regarding applications installed on a device is provided. The method includes obtaining information based on a current state of each application installed on the device; and displaying the obtained information based on the current state of each application and information identifying each application.

Abstract: A device and method for controlling rotation of a displayed image is provided. The device includes a sensor unit for detecting whether the device has been rotated; a photography unit for taking a picture of the face of a user in response to a determination that the device is rotated; a rotation determination unit for determining a rotation of the displayed image based on the captured face image of the user; and an image rotation unit for rotating the displayed image according to the determined rotation of the displayed image.

Abstract: A method and apparatus for managing content, where content received or generated in a device is automatically grouped and managed in real-time, and a computer readable recording medium having recorded thereon a program for executing the method which includes detecting whether content is received or generated by a device, grouping the received or generated content with another received or generated content, and displaying the grouped content on the device, wherein the another content includes at least one content received or generated before the detected received or generated content.

Abstract: A portable device and a method for providing a User Interface (UI) mode are provided. The portable device includes a display unit, a sensor unit for sensing a user's motion, and a control unit for controlling, if the user's motion is sensed by the sensor unit, the display unit to release a standby mode of the portable device and to output a UI mode screen corresponding to a type of the motion.

Abstract: An apparatus and method of controlling a motion of an object on a touch screen of a device including recognizing pressures at least two positions on the touch screen of the device, and controlling a motion of the object on the touch screen using a difference in pressure between the at least two recognized positions.

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.
