摘要:
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.

摘要:
A method for detecting one or more objects is disclosed. In one embodiment, the method comprises the steps of: receiving one or more induction signals caused by at least one object along one or more directions; comparing each received induction signal with a reference to detect at least one upward trend and/or at least one downward trend in the induction signal; and determining the number of objects based on the number of upward trend and/or downward trend in each received induction signal. A device for detecting one or more objects on a touch device is also disclosed.

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 the pointing object that come into contact with a touch screen, determining a rotation gesture performed by the pointing objects if the number of the pointing object is more than one, generating a control signal associated with the determined rotation gesture and executing a rotation command in response to the generated control signal.

A method of identifying a scaling 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 the pointing object, determining a scaling gesture, generating a control signal associated with the determined scaling gesture and executing the scaling gesture in response to the generated control signal.
摘要:
A method of identifying a shifting 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 the pointing objects that come into contact with the touch-sensitive surface, recording moving status and coordinates of each pointing object in an instance in which the number of the pointing objects is larger than a preset number, determining whether one pointing object moves in a direction parallel to the direction that another pointing object moves in according to the recorded moving status and the coordinates of the pointing objects and generating control signals to execute a gesture associated with the determined result.
摘要:
A method of identifying gestures on a touchpad comprises determining a first time interval between receipt and drop in a first contact signal induced by a first contact with the touchpad, recording a first start touch point and a first end touch point associated with the receipt and drop in the first contact signal, determining a gesture according to the first time interval, the first start touch point and the first end touch point and generating a control signal associated with the determined gesture.
