Abstract
A touch screen to smooth a moving trajectory of a touch unit input as a curved line and to display the moving trajectory, and a display method of the touch screen are provided. The display method of the touch screen may include sampling coordinates at touch points when a touch unit moves on a touch screen, determining whether a moving trajectory of the touch unit is a curved line according to inclination between the coordinates, and fitting the sampled coordinates to a curve and displaying the fitted curve on the touch screen upon determining that the moving trajectory of the touch unit is the curved line.
Claims23
A display method of a touch screen device, comprising:
- sampling coordinates at touch points when a touch unit moves on a touch screen;
- determining whether a moving trajectory of the touch unit is a curved line according to inclination between the sampled coordinates;
- and
- fitting the sampled coordinates to a curve and displaying the fitted curve on the touch screen upon determining that the moving trajectory of the touch unit is the curved line.
A touch screen device comprising:
- a sensing unit to sense touch;
- a display unit to display the sensed touch;
- and
- a controller to sample the sensed touch positions as coordinates, to determine whether a moving trajectory of a touch unit is a curved line, and to fit the coordinates to a curve and control the fitted coordinates to be displayed on the display unit upon determining that the moving trajectory of the touch unit is the curved line.
