The invention relates to a touch control realization method and system. At least three fixed slaved devices and a movable slaved device are arranged on a screen; then a specific position coordinate of a movable device is calculated by using the relationship of each fixed slaved device and the movable slaved device; and finally a position coordinate of touch control points is determined according to the coordinate. For the large screen, the touch control realization method and a relevant system realize the purpose of touch control and even multi-finger touch control with simplicity, and no traditional problem of ghost point exists in the multi-finger touch control realization method exists so that the touch control realization method and system are worthy of popularization and application.
Description
Method and system for implementing touch control technical field The present invention relates to a touch technology, in particular to a method and system for realizing touch. Background technique Touch technology is a popular technology at present, and it includes single-touch technology and multi-touch technology. In the single-touch technology, a touch device capable of providing a touch function is controlled by recognizing the movement of a finger on a touch input device (such as a touch screen and a touchpad) in the touch device. In the multi-touch technology, the touch device is controlled by recognizing the actions of multiple fingers on the touch input device. Regardless of the single-touch technology or the multi-touch technology, the touch device is controlled according to the movements of fingers on the touch input device. At this stage, it is more common to realize the above-mentioned touch function through the principle of resistive or capacitive touch, whi...
