摘要：
A method comprises receiving an input event generated when at least one contact is made on an interactive surface at a location corresponding to a graphical object; determining the number of contacts associated with the input event; tracking movement of the at least one contact on the interactive surface; identifying a graphical object manipulation based on the number of contacts, the movement of the at least one contact, and the graphical object type; and performing the graphical object manipulation.
