Abstract
A method of identifying a rotation gesture comprises detecting one or more induction signals induced by one or more pointing objects that come into contact with a touch-sensitive surface, determining the number of pointing objects, detecting movement statuses of the detected pointing objects, determining a rotation gesture performed by the pointing objects based on the movement statuses, generating a control signal associated with the determined rotation gesture and executing the rotation gesture in response to the generated control signal.
