Methods and systems for providing input to a computing device based on a single contact scaling gesture are provided. A scaling gesture can be performed on a touch-sensitive panel to zoom in or out of a displayed image, for example. One example of a scaling gesture can include two touch contacts moving towards or away from each other. A single contact scaling gesture can include selecting a scaling command based on a first touch input being held for a predetermined duration of time, or based on other criteria. Once the scaling command has been selected, subsequent touch input can determine both a scaling factor and a scaling direction of the scaling command. |
