Problems solved by technology

This type of conventional touch panel or conventional touch screen cannot use multiple objects (such as multiple fingers) to touch simultaneously due to the limitation of hardware conditions. Therefore, this type of conventional touch screen Gesture commands developed on a tablet or a conventional touch screen have to be limited

Embodiment Construction

[0022] figure 1 It is a schematic diagram of the operation of the method that is the operation object of the present invention implemented on the touch screen. The touch screen 1 used in the method for operating an object of the present invention can directly use a conventional touch screen 1 . Generally speaking, the touch screen 1 includes: a touch panel 10, and a display 12 capable of displaying objects 14a, 14b. Since the touchpad 10 is a transparent body, when the touchpad 10 covers the display 12 , the objects 14 a and 14 b can still be observed. The touch screen 1 can detect the position information of a plurality of touched points F1-F3 generated by pressing multiple fingers on the touch panel 10, such as figure 1 The three fingers of the user press the touched points F1 - F3 of the touch panel 10 . The position information of the touch screen 1 can be taken as absolute coordinates or relative coordinates, for example, the coordinates of the touched point F1 are (...

Abstract

The invention provides a method for operating object on a touch control screen with multi-finger which includes steps as follows: firstly, obtaining a position information of a touched point on the touch control screen; secondly, judging the touched point amount whether larger than or equal to three, and judging that region composed of position information of the plurality touched points whether containing an object; thirdly, selecting the object in the region as the secondly step, finally, processing moving, enlarging / reducing using other touch change of the touch control screen.

Description

Technical field [0001] The present invention is about the operation method of an image object, especially the method of operating objects on the touch screen with multiple fingers. Background technique [0002] A large part of the touch panel or the touch screen of Xi Zhizhi's touch screen is to use an object, such as a finger or a handwritten pen, a touchpad or a touch screen on a touch board or a touch screenPerform touch, and generate a trajectory with position coordinates.This type of Xi Zhi touchpad or Xi Zhizhi touch screen is unable to use multiple objects (such as multiple fingers) at the same time because of the limitations of hardware conditions.The gesture orders developed by the panel or the touch screen of the touch screen have to be restricted. [0003] In the "Multi -object detection method of capacitive touchpad" No. 094118951, No. 094118951, a multi -object detection method of a capacitive touch board has been revealed, and at least one preset time is identified ...
