摘要：
A method includes determining a first position of a thumb and a first position of an index finger at a first time； calculating a first distance between the thumb and the index finger at the first time based upon the first position of the thumb and index finger； determining a second position of the thumb and index finger at a second time, the second time being relatively later in time than the first time； calculating a second distance between the thumb and the index finger at the second time, based upon the second position of the thumb and index finger； identifying a pick-up gesture based upon the first distance and the second distance； selecting a first tool from a set of tools based upon a tool position of the first tool, the first tool being a real tool； and assigning the first tool to the pick-up gesture.
