Abstract
A touch screen device comprises a touch-screen controller configured to detect a touch on a touch sensitive display and to detect movement across a part of the touch sensitive display of the touch; a display controller configured to display graphical elements on the touch sensitive display and a processor configured to, in response to detection of movement of the touch: determine a first graphical element displayed on the touch sensitive display in a position corresponding to the part of the touch sensitive display across which the movement of the touch is detected; determine a position on the display for a second graphical element in relation to the position on the display of the first graphical element; and modify the display by adding the second graphical element at the determined position.
Claims18
A method of operating a device comprising a touch sensitive display, in which the method comprises:
- detecting a touch on the touch sensitive display and detecting movement of the touch across a part of the touch sensitive display;
- in response to detecting the movement of the touch, determining a first graphical element displayed on the touch sensitive display in a position corresponding to the part of the touch sensitive display across which the movement of the touch is detected;
- adding a second graphical element on the touch sensitive display;
- in which the position on the touch sensitive display of the second graphical element is determined in relation to the position on the touch sensitive display of the first graphical element.
The method of any above claim in which detecting movement of the touch comprises detecting movement of the touch within a part of the display corresponding to a graphical element displayed on the display.
A computer program stored on a computer-readable medium and comprising computer-readable instructions for performing the steps of any preceding claim.
A device comprising:
- a touch sensitive display;
- a touch-screen controller configured to detect a touch on the touch sensitive display and to detect movement across a part of the touch sensitive display of the touch;
- a display controller configured to display graphical elements on the touch sensitive display;
- a processor configured to, in response to detection of movement of the touch:
- determine a first graphical element displayed on the touch sensitive display in a position corresponding to the part of the touch sensitive display across which the movement of the touch is detected;
- determine a position on the display for a second graphical element in relation to the position on the display of the first graphical element;
- and
- modify the display by adding the second graphical element at the determined position.
