Abstract:
A display apparatus and a method of controlling the display apparatus include displaying a plurality of display items on a display screen; acquiring a coordinate value of a position on the display screen pointed to by an input device; positioning a virtual pointer on the display screen in an area of first one of the plurality of display items that is proximate to the acquired coordinate value and highlighting the first display item on the display screen; and in response to the input device pointing to a new position, moving the virtual pointer according to a new coordinate value of the new position pointed to by the input device and highlighting a second one of the plurality of display items that is proximate to the new coordinate value on the display screen.
Abstract:
A geomagnetic sensor calibration apparatus includes a geomagnetic sensor which measures at least one value of Earth's magnetic field, an initial point estimator which estimates first central points regarding the at least one value of the Earth's magnetic field by using a first linear function, a central point estimator which estimates second central points by using a second linear function and the estimated first central points, and a controller which determines whether calibrating of the geomagnetic sensor is necessary based on the estimated first central points and controls the central point estimator to estimate second central points based on whether calibration is determined to be necessary.
Abstract:
An image processing apparatus and a controlling method of the same are provided. The method includes displaying a first screen corresponding to a first application; displaying a second screen corresponding to a second application above the first screen such that the second screen overlaps at least a portion of the first screen; and displaying at least a portion of the second screen that overlaps the portion of the first screen, while controlling the first application.
Abstract:
A graphical user interface, a display apparatus and a control method thereof are provided. The display apparatus includes: a display unit which displays thereon an image comprising a plurality of user interface (UI) objects and a pointer; a pointer adjuster which generates the pointer and moves the pointer based on a user command for moving the pointer received from an input device; and a controller which controls the pointer adjuster to adjust a moving speed of the pointer according to a density of the UI objects displayed on the display unit.
Abstract:
A display apparatus and method capable of controlling the movement of a cursor are provided. The display apparatus includes an input unit which receives a cursor movement command; a display unit which displays a cursor and at least one object on a screen and moves the cursor in accordance with the cursor movement command; and a control unit which, in response to the cursor being placed in contact with the at least one object, controls the display unit to automatically move the cursor to a target point in the at least one object, wherein a size of the cursor varies depending on properties of the movement of the cursor. Therefore, it is possible to minimize the probability of a cursor mistakenly being moved to an object automatically against the intention of a user.
