Abstract
Methods for touch-based gestural command input on a device with a touch-sensitive surface and a display are disclosed. In one embodiment, a method includes displaying an electronic canvas including an object at a first magnification level; simultaneously detecting a first and a second contact on the touch-sensitive surface, wherein at least one of the first contact and the second contact on the touch-sensitive surface is at a location that corresponds to a location on the display that is away from the object; detecting a gesture made with the first and second contacts; when a velocity of the gesture is less than a predefined gesture velocity threshold, scaling the electronic canvas in accordance with the gesture; and, when the velocity of the gesture is greater than the predefined gesture velocity threshold transitioning the electronic canvas from the first magnification level to a second, predefined magnification level in response to the gesture.
