Embodiment
For making object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that embodiment described herein only in order to explain the present invention, do not limit protection scope of the present invention.
Content method for deleting in an embodiment on touch-screen, as shown in Figure 1, comprises the following steps:
Step S101: after starting the erase tool on touch-screen, when detecting the contact area obtaining touch objects and described touch-screen and changing, the contact area according to the described touch objects after change and described touch-screen adjusts the area of described erase tool on described touch-screen;
Step S102: touch-screen according to the erase tool to erase after adjustment area needs the content of wiping.
Known from the above description, content method for deleting on inventive touch screen, can adjust erase tool size on the touchscreen in real time in erase process, can realize large area erasing fast, also can realize the erasing to trickle place very easily, have very high actual application value.
As an embodiment, the step adjusting the area of described erase tool on described touch-screen according to the described touch objects after change and the contact area of described touch-screen comprises:
When detecting the contact area obtaining described touch objects and described touch-screen and increasing, increase the area of described erase tool on described touch-screen;
When detecting the contact area obtaining described touch objects and described touch-screen and reducing, reduce the area of described erase tool on described touch-screen;
The contact area that above-mentioned erase tool area on the touchscreen equals the contact area of above-mentioned touch objects and touch-screen or above-mentioned erase tool area on the touchscreen and above-mentioned touch objects and touch-screen is proportional;
The contact area of touch objects and touch-screen is adjusted at any time in the process of erasing, and then the size of adjustment erase tool, large area erasing fast can be realized, also can realize the erasing to trickle place very easily, make erase feature easy-to-use flexibly.
As an embodiment, after described touch-screen according to the erase tool to erase after adjustment area needs the content of wiping, also comprise step:
When the contact area that detection obtains described touch objects and described touch-screen is zero, exit described erase tool;
When needs exit erase tool, the contact area of adjustment touch objects and touch-screen is zero, exits erase tool simply, easily, stops erase operation, corresponds to actual needs.
As an embodiment, the step of the erase tool on described startup touch-screen comprises:
Detect the contact area of described touch objects and described touch-screen, when detecting the contact area obtaining described touch objects and described touch-screen and being more than or equal to the contact area of described touch objects and the described touch-screen pre-set, start the erase tool on described touch-screen;
When needing to wipe under can be implemented in the state of writing, directly start erase tool according to touch area, after exiting erase tool, automatically return to the state of writing, simple, convenient, be applicable to practical application.
As an embodiment, described touch objects is palm or finger, described erase tool is erasing rubber or blackboard eraser, described erasing rubber is erasing rubber that is circular or rectangular shape, and described blackboard eraser is blackboard eraser that is circular or rectangular shape, increases versatility, user-friendly, when the figure drawn, person's handwriting are regular shape, easily realize and need to wipe the overlapping of content, accurately wiping;
According to actual conditions, the shape of erasing rubber or blackboard eraser can be set, facilitate practical application at this.
In order to understand this method better, below elaborate the content method for deleting application example on an inventive touch screen, this application example realizes on Intelligent flat.
As shown in Figure 2, this application example can comprise the following steps:
Step S201: when detect palm or finger and the contact area of Intelligent flat be more than or equal to the palm that pre-sets or point and the contact area of Intelligent flat time, the erasing rubber on startup Intelligent flat, this erasing rubber is the erasing rubber of rectangular shape; According to actual conditions, on needs erasing Intelligent flat when content, start the erasing rubber on Intelligent flat, prevent maloperation;
Step S202: after starting the erasing rubber on Intelligent flat, when detecting the contact area obtaining palm or finger and Intelligent flat and increasing, increases the area of erasing rubber on Intelligent flat; When detecting the contact area obtaining palm or finger and Intelligent flat and reducing, reduce the area of erasing rubber on Intelligent flat; The area of erasing rubber on Intelligent flat equals the contact area of palm or finger and Intelligent flat; The contact area of palm or finger and Intelligent flat is adjusted at any time in the process of erasing, and then the size of adjustment erasing rubber;
Step S203: according to the content erasing rubber erasing Intelligent flat after adjustment area needing wipe, large area erasing fast can be realized, also can realize the erasing to trickle place very easily, make erase feature easy-to-use flexibly;
Step S204: when the contact area that detection obtains palm or finger and Intelligent flat is zero, exit erasing rubber; When needs exit erase tool, the contact area of adjustment palm or finger and Intelligent flat is zero, exits erasing rubber simply, easily, stops erase operation.
This application example, in the process of erasing, can adjust the contact area of palm or finger and Intelligent flat at any time, and then the size of adjustment erasing rubber, realizes the convenient object regulating erasing rubber size.If want to delete large-area notes, can with whole palm contacts Intelligent flat, now the size of erasing rubber can conform to hand size, can the notes of large area erasing fast.If user wants to wipe trickle part, palm can be lifted gently and only go to contact Intelligent flat with a finger, now the size of erasing rubber can conform to the size of finger, can wipe the notes of discreet portions.Thus conveniently achieve erase feature flexibly, improve Consumer's Experience.
