    Abstract: Systems and methods of zooming and panning an image on a multi-touch enabled computing device are provided. The difference in the mean absolute deviation of consecutive move events is used to determine the scaling factor to apply, and the translation of centroids of consecutive move events is used to determine the pan gesture to apply.
