Abstract
A touchscreen display device implements a single touch operation using a spiral rotation gesture on a touchscreen display device to magnify the display of an image. Continued spiral rotations result in continued magnification. A zoom-in or zoom-out operation is implemented by a single touch spiral rotation. In one example, a spiral rotation defining an increasing area has a corresponding action to reduce a display portion of the display screen. Similarly, a spiral rotation defining a decreasing area has a corresponding action to magnify the display portion of the display screen. A floating origin may be used to identify gestures at various positions on a touchscreen display.
