Abstract:
A display apparatus and control method thereof are provided. The display apparatus includes: a processor configured to process image data of image contents; a display configured to display the image data processed by the processor as an image; a user interface configured to sense a reaction of a user to the image displayed by the display; and a controller configured to determine a preference of the user for the image contents based on the reaction sensed by the user interface. The controller is configured to determine the preference based on an accumulated value of each reaction among a plurality of kinds of reactions generated while the image is displayed and a weight set up corresponding to the reaction. The weight corresponding to the reaction is set up according to genres of the image contents.
Abstract:
Provided is a method of measuring a heart rate in an electronic device. The method includes obtaining a face image of a subject by using the electronic device; determining a target region within the obtained face image; analyzing color information within the determined target region; and determining a heart rate of the subject on the basis of the analyzed color information. The analyzing of color information is performed on the basis of a differential arithmetic operation between a first color component and a second color component within the target region.
Abstract:
A method for providing a service of a server device is provided. The method includes selecting a donor from among users registered in the server device; selecting a recipient; and in response to the donor and the recipient being selected, providing the donor with a notification message indicating that a donation service is provided to the recipient in the name of the donor. Accordingly, user satisfaction can be improved.
Abstract:
A display apparatus is provided. The display apparatus includes: a display configured to display a virtual keyboard; an inputter configured to receive a stroke input on a key on the virtual keyboard; and a controller configured to display a character which corresponds to the key in an input window in response to the stroke input being received, and configured to perform a control operation to suggest at least one character that is likely to follow a character which corresponds to the key and display the at least one suggested character. The at least one suggested character is displayed so as not to overlap a character of a basic key on the virtual keyboard.
Abstract:
A portable device, a display apparatus, a display system, and a method for controlling power of a display apparatus thereof are provided. The method includes sensing, while a portable device operates in a standby mode, a movement of the portable device using a motion sensor, converting, using the portable device, the standby mode of the portable device into a normal mode in response to the movement of the portable device being sensed, generating, using the portable device, a pre-power on signal in response to the standby mode being converted into the normal mode, transmitting the pre-power on signal to the display apparatus, and activating, by the display apparatus, some elements of the display apparatus in response to the pre-power on signal being received.
Abstract:
An erasing device to erase an image displayed on a display apparatus, the erasing device including: a housing; a generator to generate an electromagnetic field so that the electromagnetic field is emitted from each of a plurality of portions of a tip of the housing; and a controller to control the generator to generate the electromagnetic field when the tip touches a surface of the display apparatus so that the display apparatus detecting the electromagnetic field erases an image within a preset image deletion region with a predetermined area based on a position on the surface touched by the tip, wherein the generator adjusts output of the electromagnetic field from each portion of the tip based on whether each portion of the tip touches the surface so that the display apparatus adjusts the area of the image deletion region based on the portion of the tip touched by the surface.
Abstract:
An input apparatus is provided. The input apparatus includes a communicator configured to receive a signal from a pointing apparatus, and a controller configured to control to display the pointer on a first position of the display when a start signal is received from the pointing apparatus, and when sensed position information of the pointing apparatus is received from the pointing apparatus, the controller controls to display the pointer on a second position of the display, which corresponds to the received position information of the pointing apparatus.
Abstract:
A display apparatus, an input apparatus, and a method for compensating coordinates using the same. A method for compensating coordinates using a display apparatus includes receiving movement information from an input apparatus, calculating a coordinate value based on the movement information, and displaying a cursor on the calculated coordinate value. When a button selection command is received from the input apparatus, replacing a coordinate value calculated after receiving the button selection command with a coordinate value of a stable position calculated before receiving the button selection command, and displaying the cursor on the replaced coordinate value, and manipulating an item on which the cursor is located according to the button selection command. Accordingly, the user may locate a cursor on the location that the user wants and execute a display item.
