Abstract
The invention provides an error-correcting method for a touch panel, which comprises the following steps: recording effective clicking coordinate points, moving coordinate points and lifting coordinate points respectively, comparing the coordinate points and determining whether the moving coordinate points and the lifting coordinate points are in a preset effective sensing zone, thereby accurately determining the effectiveness of clicking and moving events. The method can effectively avoid the misoperation and enhance the operation sensibility.
Description
Technical field
The present invention relates to the input technology field of touch-screen, particularly a kind of error correction method that is used for touch-screen.
Background technology
Mouse is a very important computer input equipment, form by left button, middle key, right button, roller etc., move with mousebutton by mouse and just can finish feature operation on the screen, the original intention of mouse designs is exactly easier for the operation that makes computing machine, uses the people of computer all to know the importance of mouse.It is exactly all to be moving of a pixel of a pixel when mouse moves on computer screen that mouse has a very important characteristic, so its coordinate setting on screen is very accurate, can accomplish that a pixel is not poor.After mouse moves to certain point on the screen, click the left button or the right button of mouse again, and then decontrol button, will respond a mouse event, can reach the accurate location and the purpose of response fast like this.
Nowadays, the application of screen touch interaction technique is very extensive, and finger has replaced mouse, clicks on screen and just can carry out various operations, uses not only convenient but also simple.The interactive technology that adopts finger to replace mouse of screen touch, finger moves on screen at the mobile mouse that just is equivalent on the screen, and the touch-screen that uses has electric resistance touch screen, infrared touch panel, capacitive touch screen, surface acoustic wave touch screen, near field imaging touch-screen etc. at present.The principle of finger manipulation touch-screen is as follows: just be equivalent to the left button of mouse or the action that right button is pressed when finger enters ultrared screen area, when frameing out the zone, finger upsprings with regard to the button that is equivalent to be pressed on the mouse, by a such action that enters and leave just corresponding the click event of mouse, if continuously, do twice such action fast, the double-click incident of just suitable mouse, and enter infrared screen area and do not leave when finger, finger is again on screen when mobile simultaneously, so just be equivalent to the mouse moving incident, the interactive operation on the touch-screen enters and the operation of similar mouse event is finished in the zone that frames out by a series of like this.
When finger uses on touch-screen, there are two problems: the one, people's finger thickness differs, be easy to cause pixel error, if point bigger in the screen tilt angle, error can appear clicking in the phenomenon that multipoint positioning might occur like this, gets on to finish clicking operation with finger at screen, best click angle is 70～110 °, otherwise may occur clicking inaccurate, click entanglement or do not have the phenomenon of response; The 2nd, everyone finger is in the phenomenon that vacant state all has shake, during the finger shake, target offset can appear clicking, or click and become double-click, perhaps click and become problems such as mobile, such as the coordinate that presses down on certain object when finger is (10,10), but after pressing down, finger has been shaken again simultaneously, has approximately moved two pixels and become and be (12,12) in the process of shake, system can think that this operation is a move operation of having done 2 pixels like this, and does not go to respond single-click operation originally.
In the current windows operating system, when operating an object, there are following four kinds of modes: one, response click event but immovable object, the button above the toolbar of seeing usually such as us; Two, response click event and movably object are as file in the explorer or file; Three, removable but do not respond the object of click event, as toolbar; Four, the not removable object that does not also respond click event is as some fixing toolbars.When we do certain operations on touch-screen, if run into one, three, the object of four kinds of modes, substantially there is not too big problem in the operation, picture has the button of incident, finger click scope is on whole object, promptly if the finger click on its object and no matter the finger whether move, as long as finger when frameing out the zone also in the zone of object, the capital responds accurately to be clicked and moving event, these modes are gone operation with finger, basically do not have what too big problem, but the angle of inclination is not too big when clicking, otherwise may has the pixel error.For the above-mentioned second way; if when going to operate with finger; beyond thought result appears through regular meeting; when removing to click a file with finger; if at this moment finger has been shaken; can find to have become move, in Windows operating system, also not have special disposal route targetedly because the object that the finger shake causes moves phenomenon as this.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of error correction method that is used for touch-screen that can effectively avoid misoperation and improve Operational Figure Of Merit is provided.
The present invention is achieved through the following technical solutions: a kind of error correction method that is used for touch-screen, and come right area to divide click incident and moving event by default territory, effective Perception Area, may further comprise the steps:
(1) clicks the pairing icon sizes of object according to each and set its click object range;
(2) when finger is clicked certain point on touch-screen, write down the click coordinate point of this point, and judge according to the click object range that it has been set whether this click coordinate point is effective;
If click coordinate point is in clicking object range, then this click coordinate point is effective, and forms effective click coordinate point; If in clicking object range, then this click coordinate point is not invalid for click coordinate point, and stop response;
(3) putting when effective when click coordinate, is starting point with the effective click coordinate points that forms, and gives effective perception zone to this point;
(4) when finger is mobile, write down each moving coordinate point, and it is compared with effectively clicking coordinate points, if the moving coordinate point exceeds its effective perception zone, then moving event is effective; If moving coordinate point is in its effective perception zone, then moving event is invalid;
(5) when finger lifts, write down the coordinate points of lifting of this point, and it is compared with effectively clicking coordinate points, if lift coordinate points in its effective perception zone, then click event is effective; If lifting coordinate points exceeds effective perception zone, then click event is invalid;
The described effective perception of step (3) zone for effective click coordinate points be starting point respectively up and down, left and right four direction extends 5～30 rectangles that pixel forms; , be the circle that radius forms perhaps with 5～30 pixels for being the center of circle with effective click coordinate points.
Each moving coordinate point of the described record of step (4) is for whenever moving a pixel record once.
Compared with prior art, the present invention has following beneficial effect:
The present invention is directed to the user in the maloperation that causes owing to the finger shake with the finger manipulation touch-screen, come effective perception zone of preset coordinate point by the jitter amplitude of research finger, thereby right area divides click incident and moving event, therefore can reach the purpose that reduces the misoperation rate and improve Operational Figure Of Merit.
