Touch control method and electronic system utilizing the same

摘要

A touch control method is implemented in an electronic system. A calculation of the product of a pressure value and the area over which pressure is applied are included in touch input data packets representing a touch operation, the values of net force associated with the touch input packets are thus obtained. A signal of a short press, if recognized, with a value of net force greater than a net force threshold can be recognized as a signal of a long press, thus simulating an operation of long press and triggering the selection of an object, where the selection of the object would otherwise require a long press operation. The touch control method operates to significantly speed up selection of an object.

主权项

1. A touch control system comprising:
detecting touch operations and generating electrical touch operation signals representative of the touch operations; generating digital touch operation signals based on the electrical touch operation signals, wherein the digital touch operation signals comprise a sequence of touch operation packets representative of the touch operations, wherein each packet selected from the touch operation packets comprises a pressure field, an area field, and a coordinate field, wherein the pressure field records a pressure value, the area field records a pressed area associated with the pressure value, and the coordinate field records a touch operation coordinate associated with the pressure value; generating a net force value of each input packet selected from a portion of the touch operation packets via a product calculation of a pressure value and a pressed area of the input packet, and thus to generate net force values of the portion of the touch operation packets as a net force measurement of the touch operations; determining whether at least one net force record in the net force measurement exceeds a net force threshold; and activating a graphical user interface function based on one or more touch operation coordinates in the touch operation packets upon a condition that at least one net force record.
