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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for single touch zoom using spiral rotation","description":"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.
