However, there are certain shortcomings in these two erasing methods. The former erasing method cannot realize the erasing of some areas, and the latter erasing method is relatively inefficient, and these two erasing methods are different from the actual text or The image erasing methods are quite different, not intuitive enough, and the user experience is poor

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] Please also see figure 1 and figure 2 , is a schematic diagram of the functional modules of the device for implementing the method for erasing touch screen content of the present invention. The device 10 includes a touch screen unit 11 , a control unit 12 , a storage unit 13 , an area detection unit 14 , a timing unit 15 and an erasing unit 16 . The device 10 is used to receive handwriting or input instructions input by an input device 20, the input device 20 may be a stylus or other pen-like objects, and also includes a user's finger, palm or other body parts.
[0026] When the input device 20 is in contact with the touch screen unit 11, that is, when the user uses the input device 20 to perform handwriting input on the touch screen unit 11, at this time, the touch screen unit 11 performs input judgment by detecting the coordinates of the touch pos...

A device for erasing contents of a touch screen comprises a touch screen unit, a timing unit, a memorizing unit, an area detecting unit, a control unit and an erasing unit. The memorizing unit pre-memorizes a reference area and detection time. The timing unit is started to perform timing when area detecting unit confirms that a contact region formed by an input device and the touch screen unit in contact is not smaller than the reference area. According to input device sliding tracks confirmed by the touch screen unit, the control unit confirms an erasing signal produced by the input device in preset regular sliding when the time reaches to the detection time. The erasing makes response to the erasing signal and erases the contents in the touch screen. The invention further provides a method for erasing the contents of the touch screen. By means of the method and device for erasing the contents of the touch screen, a function of locally erasing the contents of the touch screen is achieved, and the user experience is improved when the contact area reaches to the reference area and the contents are erased within the detection time in preset regular sliding.
Description
technical field [0001] The invention relates to the technical field of touch input, in particular to a method and device for erasing touch screen content. Background technique [0002] With the development of science and technology, the cost of touch input devices is getting lower and lower, and a large number of devices begin to adopt touch input. Especially on handheld devices, the application is more common. For example, most mobile phones currently on the market support handwriting input. [0003] The touch screen is the most common touch input device, and the touch screen also has the function of displaying the touch input. When using a touch screen for input, there are generally two situations in the prior art for erasing inputted content: one is to completely clear the input content, and the other is to use tools such as an eraser to clear the input content. However, there are certain shortcomings in these two erasing methods. The former erasing method cannot reali...
