In order to realize the rapid switching of the device states, the applicant carries out research, and through continuous research, a state switching method which is simple to operate and high in switching efficiency is finally provided.
It should be understood that the above-described exemplary electronic devices are only examples, and other electronic devices that may be present or later become known and may be used in the present application are also included within the scope of the present application and are hereby incorporated by reference.
The following embodiments are provided to describe the state switching method provided in the present application.
First embodiment
Referring to fig. 1, a flow diagram of a state switching method provided in this embodiment is shown, where the state switching method is applied to an electronic device with a touch screen, where the electronic device has a writing state and an erasing state, and the method may include:
step S101: after the electronic equipment enters a writing state, touch operation of a first operation object on the touch screen is detected.
And the electronic equipment enters a writing state, a touch screen of the electronic equipment displays an interface containing a writing area, and a user can write in the writing area of the touch screen by using a second operation object. The second operation object is an object capable of writing in a writing area of the touch screen, such as a touch pen (e.g., an electromagnetic pen, a capacitive pen, etc.).
According to the method and the device, after the electronic equipment enters a writing state, the touch operation of a first operation object on the touch screen is detected. 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 a writing area of the touch screen.
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 finger of the user on the touch screen.
Step S102: and if the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets the preset condition, controlling the electronic equipment to be switched to an erasing state.
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 touch control method comprises the following steps of contacting time of a first operation object and a touch control screen, contacting area of the first operation object and the touch control screen, and moving condition of the first operation object on the touch control screen.
For example, the first operation object is a finger of a user, the contact time of the finger of the user with the touch screen is the contact time of the finger of the user with the writing area of the touch screen, the contact area of the first operation object with the touch screen is the contact area of the finger of the user with the writing area of the touch screen, and the movement condition of the first operation object on the touch screen may be a displacement of the finger of the user in the writing area of the touch screen.
In this embodiment, after detecting the touch operation of the first operation object on the touch screen, it is determined whether the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets a preset condition, specifically, it is determined whether the contact time of the first operation object with the touch screen is greater than a preset first time threshold, whether the contact area of the first operation object with the touch screen is greater than a preset area threshold, and whether the displacement of the first operation object on the touch screen is smaller than a preset first displacement threshold, if the contact time of the first operation object with the touch screen is greater than the preset first time threshold, and the contact area of the first operation object with the touch screen is greater than the preset area threshold, and the displacement of the first operation object on the touch screen is smaller than the preset first displacement threshold, it may 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 control electronics switch to the erased state. It should be noted that the displacement of the first operation object on the touch screen may be a displacement within a preset time period from the first operation object contacting the touch screen, and that a displacement of the first operation object on the touch screen smaller than a preset first displacement threshold indicates that the first operation object does not move or only slightly moves.
Therefore, if the first operation object is a finger of the user, for the user, the electronic device can be switched from the handwriting state to the erasing state only by performing a single-point touch operation on the touch screen through the finger.
In this embodiment, a touch operation may be detected by a screen sensor of an electronic device, when a first operation object, such as a finger of a user, contacts a touch screen, a touch signal may be received by the screen sensor of the electronic device, the touch signal is received, which indicates that the touch operation is detected, and after the touch signal is received, a touch time and a touch position of the first operation object on the touch screen may be obtained by a driver, where it is to be noted that, starting from when the first operation object contacts the touch screen, the touch time and the touch position of the first operation object may be continuously obtained until the first operation object leaves the touch screen (that is, the first operation object does not contact the touch screen any more), for example, touch coordinates at time t1 and t1, touch coordinates at time t2 and t2, touch coordinates at time t3 and t3, and … are obtained, and a contact time of the first operation object with the touch screen may be determined by the obtained touch time (where the contact time is a contact time here Duration), the displacement of the first operation object on the touch screen can be determined by the acquired touch coordinates, for example, after the first touch time is obtained, every time a touch time is obtained, the current contact time of the first operation object with the touch screen can be obtained by subtracting the latest obtained touch time from the first touch time, the difference between the latest obtained touch time and the first touch time is the contact time of the first operation object with the touch screen, for the displacement of the first operation object on the touch screen, after the first touch coordinates are obtained, every 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 obtained touch coordinates and the first touch coordinates (the displacement can be determined based on sqrt ((x2-x1)2, (y2-y1)2), (x1, y1) is the first touch coordinates, that is the touch coordinates when the first operation object starts to contact the touch screen, (x2, y2) is the latest obtained touch coordinate), and the displacement determined based on the latest obtained touch coordinate and the first touch coordinate is the displacement of the first operation object on the touch screen.
After the electronic device enters the erasing state, the first operation object can perform erasing operation so as to erase the content written in the writing area displayed on the touch screen.
For example, the first operation object is a finger, the user usually erases the written content by sliding the finger, and for some devices, the sliding finger may trigger other functions, such as a page turning function, in order to avoid triggering other functions to affect the erasing when the written content is erased by the finger, and after the electronic device enters the erasing state, the triggering of other functions may be intercepted.
According to the state switching method provided by the embodiment of the application, after the electronic equipment enters the writing state, the touch operation of the first operation object on the touch screen can be detected, and when the touch operation information corresponding to the touch operation meets the preset condition, the electronic equipment can be controlled to be switched to the erasing state. According to the state switching method, the state of the electronic equipment can be switched based on simple touch operation of the first operation object, the switching mode is simple and efficient, and user experience is good.
Second embodiment
On the basis of the state switching method provided in the foregoing embodiment, the present embodiment provides another state switching method, where the state switching method is applied to an electronic device with a touch screen, where the electronic device has a writing state and an erasing state, please refer to fig. 2, which shows a flowchart of the state switching method provided in the present embodiment, and may include:
step S201: after the electronic equipment enters a writing state, touch operation of a first operation object on the touch screen is detected.
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 finger of the user on the touch screen.
Step S202: and if the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets the preset condition, controlling the electronic equipment to be switched to an erasing state.
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 touch control method comprises the following steps of contacting time of a first operation object and a touch control screen, contacting area of the first operation object and the touch control screen, and moving condition of the first operation object on the touch control screen.
Wherein the preset condition may include: the contact time of the first operation object and the touch screen is greater than a preset first time threshold; the contact area between the first operation object and the touch screen is larger than a preset area threshold value; the displacement of the first operation object on the touch screen is smaller than a preset first displacement threshold value.
It should be noted that, in the embodiment, the specific implementation process and the related explanation of steps S201 to S202 may refer to the specific implementation process and the related explanation of steps S101 to S102 in the first embodiment, and this embodiment is not described herein again.
Step S203: and after the electronic equipment is controlled to be switched to the erasing state, drawing and displaying the erasable area.
Wherein the erasable area may indicate which portion of the written content may be erased by the user.
Optionally, when the erasable area is drawn and displayed, the erasable area of the set shape may be drawn and displayed based on a contact point of the first operation object and the touch screen and a preset graphic size.
For example, a circular erasable area may be drawn with the contact point of the first operation object and the touch screen as the center and the preset graphic size as the radius, and for example, a square erasable area may be drawn with the contact point of the first operation object and the touch screen as the center and the preset graphic size as the side length.
In a possible implementation manner, the erasable area may be continuously drawn after the electronic device is controlled to switch to the erasing state, that is, the erasable area with the set shape may be drawn based on the latest contact point of the first operation object and the touch screen and the preset graphic size. Considering the refresh rate limitation of some screens (such as an ink screen), in another possible implementation manner, an erasable area of a set shape may be drawn only at the moment when the control electronic device is switched to the erase state, based on the contact point of the first operation object and the touch screen and the preset graphic size, and the erasable area is not drawn any more during the erase process.
Optionally, after it is determined that the electronic device needs to enter the erase state, a prompt message that the electronic device enters the erase state may be further output to prompt the user that the electronic device currently enters the erase state, and the user may perform an erase operation. Optionally, the prompt message may be output in a form of voice or text, for example, a prompt voice of the electronic device entering the erase state is played, or a prompt text of the electronic device entering the erase state is displayed.
Step S204: and erasing the writing content in the erasable area based on the operation of the first operation object in the erasable area.
Based on the operation of the first operation object in the erasable area, there are various ways to erase the written content in the erasable area: in a possible implementation manner, the writing content operated by the first operation object in the erasable area can be erased directly in response to the operation of the first operation object in the erasable area; considering that there may be a false touch operation, in order to avoid responding to the false touch operation, in another possible implementation manner, it may be detected whether the displacement of the first operation object in the operable area is greater than a preset second displacement threshold, and if the displacement of the first operation object in the operable area is greater than the preset second displacement threshold, it indicates that the operation of the first operation object in the operable area is an erasing operation, and is not a false touch operation, the writing content operated by the first operation object in the erasable area is erased in response to the operation of the first operation object in the erasable area.
The applicant finds that, in the course of implementing the present application, currently, a touch screen device (such as an ink screen device) has a scheme of writing with a pen tip and erasing with a pen tail, that is, writing with a pen tip of a touch pen in a writing area of a screen, and in the writing process, if the written content is to be erased, turning over the touch pen and erasing the written content with the pen tail of the touch pen. It can be understood that, during the writing process, the user may need to modify many times, that is, the user needs to erase the written content many times, which means that the user needs to frequently turn over the stylus pen, however, frequently turning over the stylus pen is prone to cause wrist fatigue, and if the material of the pen tail of the stylus pen is too hard, the screen is damaged by frequent erasing, and if the material is too soft, the material is easily worn and needs to be replaced frequently. Compared with the scheme of writing by a pen point and erasing by a pen tail, the device state switching can be realized by the single-point touch operation of the finger without turning over the touch control pen, the written content is erased by the finger without damaging a screen or wearing the touch control pen,
according to the state switching method provided by the embodiment of the application, after the electronic equipment enters the writing state, the touch operation of a first operation object on the touch screen can be detected, the electronic equipment can be controlled to be switched to the erasing state when the touch operation information corresponding to the touch operation meets the preset condition, the erasable area can be drawn and displayed after the electronic equipment is switched to the erasing state, and the writing 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 by the embodiment of the application can realize the state switching of the electronic equipment based on the simple touch operation of the first operation object, the switching mode is simple and efficient, after the state switching is carried out to the erasing state, the erasing of the written content in the erasable area can be realized based on the operation of the first operation object in the erasable area, and the user experience is good.
Third embodiment
It can be understood that, when a user erases written content based on a first operation object, in order to ensure continuity of an erasing process and enable the user to have a better erasing experience, in a case that the first operation object may leave the touch screen or leave the erasable area for some reason (for example, the user lifts up a hand because the user needs to adjust the erased content), another state switching method is provided in an embodiment of the present application, and is applied to an electronic device having a touch screen, where the electronic device has a writing state and an erasing state, please refer to fig. 3, which shows a flowchart of the state switching method provided in this embodiment, and may include:
step S301: after the electronic equipment enters a writing state, touch operation of a first operation object on the touch screen is detected.
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 finger of the user on the touch screen.
Step S302: and if the touch operation information corresponding to the touch operation of the first operation object on the touch screen meets the preset condition, controlling the electronic equipment to be switched to an erasing state.
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 touch control method comprises the following steps of contacting time of a first operation object and a touch control screen, contacting area of the first operation object and the touch control screen, and moving condition of the first operation object on the touch control screen.
Wherein the preset condition may include: the contact time of the first operation object and the touch screen is greater than a preset first time threshold; the contact area between the first operation object and the touch screen is larger than a preset area threshold; the displacement of the first operation object on the touch screen is smaller than a preset first displacement threshold value.
It should be noted that, in the embodiment, the specific implementation process and the related explanation of steps S301 to S302 may refer to the specific implementation process and the related explanation of steps S101 to S102 in the first embodiment, and details are not described herein in this embodiment.
Step S303: and drawing and displaying the erasable area after the electronic equipment is controlled to be switched to the erasing state.
Optionally, after it is determined that the electronic device needs to enter the erase state, a prompt message that the electronic device enters the erase state may be further output to prompt the user that the electronic device currently enters the erase state, and the user may perform an operation. Alternatively, the prompt may be output in voice or text form.
Step S304: and erasing the written content in the erasable area based on the operation of the first operation object in the erasable area.
It should be noted that, in the embodiment, the specific implementation process and the related explanation of steps S303 to S304 refer to the specific implementation process and the related explanation of steps S203 to S204 in the second embodiment, which is not described herein again.
Step S305: and if the first operation object is detected to be lifted, or the first operation object is detected to slide out of a writing area on the touch screen, controlling the electronic equipment to be switched to an erasing protection state.
It should be noted that, the control of the electronic device to switch to the erase protection state essentially delays the electronic device from exiting the erase state, thereby ensuring the consistency of the erase.
Step S306 a: and controlling the electronic equipment to be switched to an erasing state if the first operation object is detected to be in contact with the erasable area within the preset erasing state protection time.
And when the electronic equipment is controlled to be switched to the erasing protection state, counting the time of the electronic equipment in the erasing protection state.
If the first operation object is detected to be in contact with the erasable area within the preset erasing state protection time, the first operation object is indicated to continue to perform the erasing operation, at this time, the electronic device is controlled to be switched to the erasing state, that is, the electronic device recovers the erasing state, and after the electronic device recovers the erasing state, the step S304 and the subsequent steps can be executed.
