[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Currently, the method of switching a touch screen device from a writing state to an erasing state is mostly based on an interface icon switching method, that is, when the state needs to be switched, first click on the state switching interface, and then click on the switch button in the state switching interface. It can be seen that the switching process is relatively cumbersome and the switching efficiency is not high.

[0050] In order to achieve rapid switching of device states, the applicant conducted research and, through continuous research, finally proposed a state switching method with simple operation and high switching efficiency. The state switching method can be applied to electronic devices with a touch screen and a writing state and an erasing state. Exemplarily, the electronic device can be a mobile phone, PAD, tablet computer, handheld computer, etc.

[0051] It should be noted that those skilled in the art should understand that the electronic devices listed above are only examples, and other existing or future electronic devices that are applicable to the present application should also be included in the protection scope of the present application and are included here by reference.

[0052] Next, the state switching method provided by the present application is introduced through the following embodiments.

[0053] First embodiment

[0054] This embodiment provides a state switching method, which is applied to an electronic device with a touch screen. The electronic device has a writing state and an erasing state. Figure 1 , which shows a schematic flow chart of the state switching method provided in this embodiment, and may include:

[0055] Step S101: After the electronic device enters a writing state, a touch operation of a first operation object on the touch screen is detected.

[0056] The electronic device enters the writing state, and the touch screen of the electronic device displays an interface with a writing area, and the user can use the second operation object to write in the writing area of ​​the touch screen. The second operation object is an object that can be written in the writing area of ​​the touch screen, such as a stylus (such as an electromagnetic pen, a capacitive pen, etc.).

[0057] The present application detects a touch operation of the first operation object on the touch screen after the electronic device enters a writing state. Optionally, the touch operation of the first operation object on the touch screen may be but is not limited to a touch operation of the first operation object on the writing area of ​​the touch screen.

[0058] Optionally, the first operation object may be but is not limited to a finger of a user, and the touch operation of the first operation object on the touch screen may be a single-point touch operation of the user's finger on the touch screen.

[0059] Step S102: If the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets a preset condition, the electronic device is controlled to switch to an erasing state.

[0060] The touch operation information corresponding to the touch operation of the first operation object on the touch screen may include but is not limited to: the contact time between the first operation object and the touch screen, the contact area between the first operation object and the touch screen, and the movement of the first operation object on the touch screen.

[0061] Exemplarily, the first operation object is the user's finger, then the contact time between the first operation object and the touch screen is the contact time between the user's finger and the writing area of ​​the touch screen, the contact area between the first operation object and the touch screen is the contact area between the user's finger and the writing area of ​​the touch screen, and the movement of the first operation object on the touch screen can be the displacement of the user's finger in the writing area of ​​the touch screen.

[0062] After detecting the touch operation of the first operation object on the touch screen, this embodiment determines whether the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets the preset conditions. Specifically, it determines whether the contact time between the first operation object and the touch screen is greater than the preset first time threshold, whether the contact area between the first operation object and the touch screen is greater than the preset area threshold, and whether the displacement of the first operation object on the touch screen is less than the preset first displacement threshold. If the contact time between the first operation object and the touch screen is greater than the preset first time threshold, and the contact area between the first operation object and the touch screen is greater than the preset area threshold, and the displacement of the first operation object on the touch screen is less than the preset first displacement threshold, it can be considered that the user intends to erase the written content, and the electronic device needs to be switched from the writing state to the erasing state. In view of this, the electronic device is controlled to switch to the erasing state. It should be noted that the displacement of the first operation object on the touch screen can be the displacement within a preset time period from the first operation object contacting the touch screen. If the displacement of the first operation object on the touch screen is less than the preset first displacement threshold, it indicates that the first operation object has not moved or has only moved slightly.

[0063] It can be seen that if the first operation object is a user's finger, the user only needs to perform a single-point touch operation on the touch screen with his finger to switch the electronic device from the handwriting state to the erasing state.

[0064] In this embodiment, the touch operation can be detected by the screen sensor of the electronic device. When the first operation object, such as the user's finger, touches the touch screen, the touch signal can be received by the screen sensor of the electronic device. Receiving the touch signal indicates that the touch operation is detected. After receiving the touch signal, the touch time and touch position of the first operation object on the touch screen can be obtained through the driver. It should be noted that from the time the first operation object touches the touch screen, the touch time and touch position of the first operation object will be continuously obtained until the first operation object leaves the touch screen (that is, the first operation object no longer touches the touch screen). For example, the touch coordinates at time t1 and time t1, the touch coordinates at time t2 and time t2, the touch coordinates at time t3 and time t3, etc. are obtained. The contact time of the first operation object and the touch screen (the contact time here is the contact duration) can be determined through the obtained touch time, and the touch coordinates of the first operation object can be determined through the obtained touch coordinates. For example, after obtaining the first touch moment, each time a touch moment is obtained, the current contact time between the first operation object and the touch screen can be obtained by subtracting the latest touch moment from the first touch moment, and the difference between the last touch moment and the first touch moment is the contact time between the first operation object and the touch screen. For the displacement of the first operation object on the touch screen, after obtaining the first touch coordinate, each time a touch coordinate is obtained, the current displacement of the first operation object on the touch screen can be determined based on the latest touch coordinate and the first touch coordinate (the displacement can be determined based on sqrt((x2-x1)2, (y2-y1)2), (x1, y1) is the first touch coordinate, that is, the touch coordinate when the first operation object starts to contact the touch screen, and (x2, y2) is the latest touch coordinate). The displacement determined based on the last touch coordinate and the first touch coordinate is the displacement of the first operation object on the touch screen.

[0065] After the electronic device enters the erasing state, the first operating object can perform an erasing operation to erase the content written in the writing area displayed on the touch screen.

[0066] Exemplarily, the first operation object is a finger, and the user usually erases written content by sliding the finger. For some devices, sliding the finger may trigger other functions, such as page turning. In order to avoid triggering other functions and affecting erasure when erasing written content with a finger, the triggering of other functions can be intercepted after the electronic device enters the erasing state.

[0067] The state switching method provided in the embodiment of the present application can detect the touch operation of the first operation object on the touch screen after the electronic device enters the writing state, and when the touch operation information corresponding to the touch operation meets the preset conditions, the electronic device can be controlled to switch to the erasing state. The state switching method provided in the embodiment of the present application can realize the switching of the electronic device state based on the simple touch operation of the first operation object, the switching method is simple and efficient, and the user experience is good.

[0068] Second embodiment

[0069] Based on the state switching method provided in the above embodiment, this embodiment provides another state switching method, which is applied to an electronic device with a touch screen, and the electronic device has a writing state and an erasing state. Figure 2 , which shows a schematic flow chart of the state switching method provided in this embodiment, and may include:

[0070] Step S201: After the electronic device enters the writing state, detecting a touch operation of a first operation object on the touch screen.

[0071] Optionally, the first operation object may be but is not limited to a finger of a user, and the touch operation of the first operation object on the touch screen may be a single-point touch operation of the user's finger on the touch screen.

[0072] Step S202: If the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets a preset condition, the electronic device is controlled to switch to an erasing state.

[0073] The touch operation information corresponding to the touch operation of the first operation object on the touch screen may include but is not limited to: the contact time between the first operation object and the touch screen, the contact area between the first operation object and the touch screen, and the movement of the first operation object on the touch screen.

[0074] Among them, the preset conditions may include: the contact time between the first operation object and the touch screen is greater than the preset first time threshold; the contact area between the first operation object and the touch screen is greater than the preset area threshold; the displacement of the first operation object on the touch screen is less than the preset first displacement threshold.

[0075] It should be noted that the specific implementation process and related explanations of steps S201 to S202 in this embodiment can refer to the specific implementation process and related explanations of steps S101 to S102 in the first embodiment, and this embodiment will not be repeated here.

[0076] Step S203: after controlling the electronic device to switch to the erasing state, drawing and displaying the erasable area.

[0077] The erasable area may indicate which part of the written content the user can erase.

[0078] Optionally, when drawing and displaying the erasable area, the erasable area of ​​a set shape may be drawn and displayed based on the contact point between the first operation object and the touch screen and a preset graphic size.

[0079] For example, a circular erasable area with the contact point between the first operation object and the touch screen as the center and the preset graphic size as the radius can be drawn. For another example, a square erasable area with the contact point between the first operation object and the touch screen as the center and the preset graphic size as the side length can be drawn.

[0080] In one possible implementation, after the electronic device is controlled to switch to the erasing state, the erasable area can be continuously drawn, that is, based on the latest contact point between the first operation object and the touch screen and the preset graphic size, the erasable area of ​​the set shape is drawn. Considering the refresh rate limit of some screens (such as ink screens), in another possible implementation, the erasable area of ​​the set shape can be drawn based on the contact point between the first operation object and the touch screen and the preset graphic size only at the moment when the electronic device is controlled to switch to the erasing state, and the erasable area is no longer drawn during the erasing process.

[0081] Optionally, after determining that the electronic device needs to enter the erase state, a prompt message indicating that the electronic device has entered the erase state may be output to prompt the user that the electronic device has currently entered the erase state and the user may perform an erase operation. Optionally, the prompt message may be output in voice or text form, for example, playing a prompt voice indicating that the electronic device has entered the erase state, or displaying a prompt text indicating that the electronic device has entered the erase state.

[0082] Step S204: based on the operation of the first operation object in the erasable area, erasing the written content in the erasable area.

[0083] Based on the operation of the first operation object in the erasable area, there are multiple ways to implement erasing the written content in the erasable area: in one possible implementation method, the operation of the first operation object in the erasable area can be directly responded to, and the written content of the first operation object in the erasable area can be erased; considering the possible existence of accidental touch operations, in order to avoid responding to accidental touch operations, in another possible implementation method, it can be detected whether the displacement of the first operation object in the operable area is greater than a preset second displacement threshold; if the displacement of the first operation object in the operable area is greater than the preset second displacement threshold, it means that the operation of the first operation object in the operable area is an erasing operation, not an accidental touch operation, then the operation of the first operation object in the erasable area is responded to, and the written content of the first operation object in the erasable area is erased.

[0084] In the process of implementing the present application, the applicant discovered that currently, touch screen devices (such as ink screen devices) have a solution of writing with the tip of the pen and erasing with the tail of the pen, that is, use the tip of the stylus to write in the writing area of ​​the screen. During the writing process, if you want to erase the written content, flip the stylus and use the tail of the stylus to erase the written content. It is understandable that the user may need to make multiple modifications during the writing process, that is, the user needs to erase the written content multiple times, which means that the user needs to flip the stylus frequently. However, frequent flipping of the stylus can easily lead to wrist fatigue. Moreover, if the material of the tail of the stylus is too hard, frequent erasing will damage the screen. If the material is too soft, it is easy to wear and needs to be replaced frequently. Compared with the solution of writing with the tip of the pen and erasing with the tail of the pen, the present application can realize the switching of device status through a single-point touch operation of the finger without flipping the stylus, and erasing the written content with the finger will not damage the screen or wear the stylus.

[0085] The state switching method provided in the embodiment of the present application can detect the touch operation of the first operation object on the touch screen after the electronic device enters the writing state, and when the touch operation information corresponding to the touch operation meets the preset conditions, the electronic device can be controlled to switch to the erasing state. After the electronic device switches to the erasing state, the erasable area can be drawn and displayed, and the written content in the erasable area can be erased based on the operation of the first operation object in the erasable area. The state switching method provided in the embodiment of the present application can realize the switching of the electronic device state based on the simple touch operation of the first operation object. The switching method is simple and efficient. After switching to the erasing state, the written content in the erasable area can be erased based on the operation of the first operation object in the erasable area, and the user experience is good.

[0086] Third embodiment

[0087] It is understandable that when the user erases the written content based on the first operation object, the first operation object may leave the touch screen or the erasable area for some reason (for example, the user raises his hand because he needs to adjust the erased content). In order to ensure the continuity of the erasing process and give the user a better erasing experience, the embodiment of the present application provides another state switching method, which is applied to an electronic device with a touch screen, and the electronic device has a writing state and an erasing state. Please refer to Figure 3 , which shows a schematic flow chart of the state switching method provided in this embodiment, and may include:

[0088] Step S301: After the electronic device enters the writing state, detecting a touch operation of a first operation object on the touch screen.

[0089] Optionally, the first operation object may be but is not limited to a finger of a user, and the touch operation of the first operation object on the touch screen may be a single-point touch operation of the user's finger on the touch screen.

[0090] Step S302: If the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets a preset condition, the electronic device is controlled to switch to an erasing state.

[0091] The touch operation information corresponding to the touch operation of the first operation object on the touch screen may include but is not limited to: the contact time between the first operation object and the touch screen, the contact area between the first operation object and the touch screen, and the movement of the first operation object on the touch screen.

[0092] Among them, the preset conditions may include: the contact time between the first operation object and the touch screen is greater than the preset first time threshold; the contact area between the first operation object and the touch screen is greater than the preset area threshold; the displacement of the first operation object on the touch screen is less than the preset first displacement threshold.

[0093] It should be noted that the specific implementation process and related explanations of steps S301 to S302 in this embodiment can refer to the specific implementation process and related explanations of steps S101 to S102 in the first embodiment, and this embodiment will not be repeated here.

[0094] Step S303: after controlling the electronic device to switch to the erasing state, drawing and displaying the erasable area.

[0095] Optionally, after determining that the electronic device needs to enter the erase state, a prompt message that the electronic device enters the erase state may be output to prompt the user that the electronic device currently enters the erase state, and the user may perform an operation. Optionally, the prompt message may be output in voice or text form.

[0096] Step S304: based on the operation of the first operation object in the erasable area, erasing the written content in the erasable area.

[0097] It should be noted that the specific implementation process and related explanations of steps S303 to S304 in this embodiment can be found in the specific implementation process and related explanations of steps S203 to S204 in the second embodiment, which will not be elaborated in this embodiment.

[0098] Step S305: If it is detected that the first operation object is lifted, or if it is detected that the first operation object slides out of the writing area on the touch screen, the electronic device is controlled to switch to the erasure protection state.

[0099] It should be noted that controlling the electronic device to switch to the erasure protection state is essentially to delay the electronic device from exiting the erasure state, thereby ensuring the continuity of the erasure.

[0100] Step S306a: within the preset erasing state protection time, if it is detected that the first operating object contacts the erasable area, the electronic device is controlled to switch to the erasing state.

[0101] While controlling the electronic device to switch to the erasure protection state, the time the electronic device is in the erasure protection state is counted.

[0102] Within the preset erasing state protection time, if it is detected that the first operating object contacts the erasable area, it indicates that the first operating object continues to perform the erasing operation. At this time, the electronic device is controlled to switch to the erasing state, that is, the electronic device restores the erasing state. After the electronic device restores the erasing state, step S304 and subsequent steps can be executed.

[0103] Step S306b: If it is detected that the electronic device is in the erasure protection state for a period exceeding a preset erasure state protection time, or if it is detected that the second operation object contacts the writing area of ​​the touch screen, the electronic device is controlled to switch to the writing state.

[0104] The second operation object is an object that can be used for writing in the writing area of ​​the touch screen, such as a touch pen (such as an electromagnetic pen, a capacitive pen, etc.).

[0105] It should be noted that if it is detected that the electronic device is in the erasing protection state for a period exceeding the preset erasing state protection time, it is considered that the first operation object will not continue the erasing operation, and the electronic device is controlled to switch to the writing state, that is, the electronic device exits the erasing state. If it is detected that the second operation object contacts the writing area of ​​the touch screen, indicating that the user wants to perform a writing operation, the electronic device is controlled to switch to the writing state.

[0106] The state switching method provided by the embodiment of the present application can detect the touch operation of the first operation object on the touch screen after the electronic device enters the writing state. When the touch operation information corresponding to the touch operation meets the preset conditions, the electronic device can be controlled to switch to the erasing state. It can be seen that the embodiment of the present application can realize the efficient switching of the electronic device state. After the electronic device switches to the erasing state, the erasable area can be drawn and displayed. Based on the operation of the first operation object in the erasable area, the written content in the erasable area is erased. In order to ensure the continuity of erasing, when the first operation object is detected to be lifted, or when the first operation object is detected to slide out of the writing area on the touch screen, the electronic device can be controlled to switch to the erasing protection state. Within the preset erasing state protection time, if the first operation object is detected to contact the erasable area, the electronic device is controlled to restore the erasing state. The state switching method provided by the embodiment of the present application can realize the efficient switching of the electronic device state and the efficient erasing of the written content, and can also ensure the continuity of erasing, and the user experience is good.
