It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent.
For example, in one embodiment, one technical feature is recited: when the erasing function is in the enabled state, the display mode of the eraser icon is different from that when the erasing function is in the disabled state. In another embodiment, another technical feature is recited: the eraser operation control moves along with the movement of the eraser icon. Since the above two technical features are not mutually contradictory, after reading the present specification, it should be understood by those skilled in the art that an embodiment having both of these two features is also an alternative embodiment, that is, the display manner of the eraser icon is different between the case where the erasing function is in the enabled state and the case where the erasing function is in the disabled state; the eraser operation control moves along with the movement of the eraser icon.
Example 1
Fig. 2 is a flow chart of an alternative erase method according to an embodiment of the present application, as shown in fig. 2, the method including the steps of: step S102 to step S110.
And S102, displaying an eraser icon, wherein the eraser icon is used for erasing handwriting.
Under the condition that the erasing function is in an enabled state, erasing the content displayed on the display screen; in the case where the erasing function is in the disabled state, the content displayed on the display screen cannot be erased.
As an alternative embodiment, the eraser icon is displayed in a different manner when the erasing function is in the enabled state than when the erasing function is in the disabled state. Specifically, the different display modes of the eraser icon include at least one of the following: the color of the eraser icon is different, the shape of the eraser icon is different, and the line type of the eraser icon is different. For example, when the erase function is in the enabled state, the line type composing the eraser icon is a solid line; in the case where the erase function is in the disabled state, the line type constituting the eraser icon is a dotted line. For another example, when the erasing function is in the enabled state, lines forming the eraser icon are black; in the case where the erase function is disabled, the lines making up the eraser icon are grey.
Different display modes of the eraser icon are set by the erasing function in the enabled state and the erasing function in the disabled state so as to remind a user whether the eraser is in the usable state or not, and the eraser is very humanized.
As an alternative embodiment, after the eraser icon is displayed, the erase function of the eraser icon is disabled.
As another optional implementation, after displaying the eraser icon, the erasing function of the eraser icon is in an enabled state, and after displaying the eraser icon and before or after receiving the sliding touch signal, the method further comprises: receiving an erasing function closing instruction; and in response to the erasing function closing instruction, closing the erasing function, wherein after the erasing function is closed, the erasing function is in a disabled state.
As an alternative embodiment, before, after or simultaneously with the display of the eraser icon, the eraser operation control is displayed, and the erasing function closing instruction is generated by touching the eraser operation control. And the user touches the blackboard eraser operation control to generate an erasing function closing instruction.
The eraser operation control may have multiple display modes, and specifically, may be displayed in a graphical or textual manner, for example, a left rectangular icon and a right rectangular icon are used to display the eraser operation control, for example, a user may start an erasing function by clicking the left rectangular icon, and a user may close the erasing function by clicking the right rectangular icon. For another example, a circular icon is used for showing the blackboard eraser operation control, the user clicks the circular icon to start the erasing function, and the user clicks the circular icon again to close the erasing function.
And step S104, receiving a sliding touch signal, wherein the sliding touch signal is used for triggering the mobile blackboard eraser icon.
And S106, responding to the sliding touch signal, moving the eraser icon to a target position, wherein the erasing function of the eraser icon is in a forbidden state in the moving process.
And generating a sliding touch signal in the process that the user moves the eraser icon by hand to slide on the display screen. For example, a user may want to erase a few words displayed in the lower right corner of the display, but many words are displayed in the lower right corner of the display, and if the user creates an eraser in the lower right corner of the display, other words may be erased by mistake. The upper left corner of the display screen does not display any content, a user creates an eraser on the upper left corner of the display screen, and moves an eraser icon to slide on the display screen by hand, so that the eraser icon is moved from the upper left corner of the display screen to the position of the character which is wanted to be erased at the lower right corner.
In the process of moving the eraser icon, the erasing function is in a forbidden state, and the content which is not wanted to be erased cannot be erased by mistake.
As an alternative embodiment, the position of the eraser operation control is not changed during the process of moving the eraser icon. For example, the user creates an eraser in the upper left corner of the display screen, displays an eraser icon and an eraser operation control, both of which are displayed in the upper left corner of the display screen. And then the user moves the eraser icon by hand, and the eraser icon is moved to the lower right corner of the display screen, and in the process, the position of the eraser operation control is unchanged and is displayed in the upper left corner of the display screen all the time. For another example, the user creates an eraser in the upper left corner of the display screen, and displays an eraser icon and an eraser operation control, wherein the eraser icon is displayed in the upper left corner of the display screen, and the eraser operation control is displayed in the middle of the display screen. And then the user moves the eraser icon by hand, and moves the eraser icon to the lower right corner of the display screen, and in the process, the position of the eraser operation control is unchanged and is displayed in the middle of the display screen all the time.
The advantages of this approach are: the display position of the blackboard eraser operation control is unchanged all the time, and a user does not need to particularly memorize the position of the blackboard eraser operation control.
As an alternative embodiment, the position of the eraser operation control changes during the movement of the eraser icon. This can be divided into two cases again:
the first condition is as follows: the relative positions of the eraser operation control and the eraser icon are kept unchanged. The advantages of this approach are: because the user moves the eraser icon with one hand, the distance between the position of the eraser icon and the other hand of the user is also short, the relative positions of the eraser operation control and the eraser icon are kept unchanged, the distance between the eraser operation control and the eraser icon is short, and the user can conveniently operate the eraser operation control with the other hand.
Case two: when the eraser icon moves, the position of the eraser operation control also changes, but the relative position of the eraser operation control and the eraser icon changes. For example, the positions displayed by the eraser operation control can only be a plurality of preset positions in the display screen, and for example, the positions displayed by the eraser operation control can only be the positions of four corners of the display screen. When the eraser icon moves to the left half part area of the display screen, the eraser operation control is displayed at the upper left corner or the lower left corner of the display screen; when the eraser icon moves to the right half area of the display screen, the eraser operation control is displayed at the upper right corner or the lower right corner of the display screen.
And step S108, receiving an erasing function starting instruction of the eraser icon.
And the user touches the blackboard eraser operation control to generate an erasing function starting instruction. As described above, the two adjacent rectangular icons can be used to display the eraser operation control, for example, the user clicks the left rectangular icon to turn on the erasing function, and clicks the right rectangular icon to turn off the erasing function. For another example, a circular icon is used for showing the blackboard eraser operation control, the user clicks the circular icon to start the erasing function, and the user clicks the circular icon again to close the erasing function.
Step S110, an erasing function of the eraser icon is turned on, wherein after the erasing function is turned on, the erasing function is in an enabled state.
After receiving the erasing function starting command, starting the erasing function, and erasing the content to be erased by using the eraser.
In the embodiment of the application, a user can create an eraser in a blank display area of a display screen, when the user wants to erase the content displayed in the target area, the user moves an eraser icon to the target area by hand, in the moving process, the erasing function is in a disabled state, the content which is not wanted to be erased can not be erased by mistake, after the eraser icon moves to the target area, the erasing function is started, and after the erasing function is started, the erasing function is in an enabled state, and the content displayed in the target area can be erased. The user can create the eraser in the blank display area of the display screen, the content which is not wanted to be erased cannot be erased by mistake, the erasing function is in a forbidden state in the process of moving the eraser icon to the target area, the content which is not wanted to be erased cannot be erased by mistake, the erasing function is started after the eraser icon is moved to the target area, the erasing function is enabled to erase the content displayed in the target area, the effect of accurate erasing is achieved, and the problem that the content which is not wanted to be erased is erased by mistake is avoided.
Optionally, after the erasing function of the eraser icon is turned on, the method further comprises: receiving an erasing touch signal; clearing and erasing the content displayed in the area indicated by the touch signal; after the content displayed in the area indicated by the erasing touch signal is cleared, an erasing ending instruction is received; and stopping displaying the eraser icon in response to the erasing end instruction.
When the user finishes erasing, the hand leaves the display screen, the display screen detects a signal generated by the operation that the hand of the user leaves the eraser icon, the display of the eraser icon is stopped, the user stops displaying the eraser icon as long as the hand of the user leaves the eraser icon, the user does not need to perform extra operation of closing the erasing function, the time of the user is saved, and the use is very intelligent.
Optionally, after the erasing function of the eraser icon is turned on, the method further comprises: receiving an erasing touch signal; clearing and erasing the content displayed in the area indicated by the touch signal; after the content displayed in the area indicated by the erasing touch signal is cleared, an erasing ending instruction is received; and responding to the erasing end instruction, and stopping displaying the eraser icon and the eraser operation control.
When the user finishes erasing, the hand leaves the display screen, the display screen detects a signal generated by the operation that the hand of the user leaves the eraser icon, the display of the eraser icon and the eraser operation control is stopped as long as the hand of the user leaves the eraser icon, the user does not need to perform extra operation of closing the erasing function, the time of the user is saved, and the use is very intelligent.
Optionally, before displaying the eraser icon, the method further comprises: receiving an eraser creating instruction, and displaying an eraser icon and an eraser operation control, wherein the method comprises the following steps: and responding to the eraser creating instruction, displaying an eraser icon and an eraser operation control, wherein the displayed position of the eraser operation control and the displayed position of the eraser icon have a preset relation. The eraser creation instruction may be a multi-touch signal.
For example, the user may contact the palm of the hand with the display screen, or may use multiple fingers to simultaneously touch the display screen, creating an eraser when the display screen receives a multi-touch signal. The position of the eraser operation control display can be very close to the position of the eraser icon display, for example, the eraser operation control display is within ten centimeters of the eraser icon, so that a user can conveniently operate the eraser icon with one hand and operate the eraser operation control with the other hand.
Example 2
FIG. 3 is a flow chart of another alternative erase method according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of: step S302 to step S312.
Step S302, the blackboard eraser is created through gestures.
The user may contact the palm of the hand with the display screen or, alternatively, use multiple fingers to simultaneously touch the display screen, creating an eraser when the display screen receives a multi-touch signal.
In step S304, a plurality of operation keys are formed beside the eraser, wherein the operation keys include a key for enabling the erasing function or closing the erasing function.
The operation key is the eraser operation control.
Step S306, when the content in the frame needs to be erased, the function of the eraser is closed, and the eraser is changed into a grey dotted frame.
Step S308, dragging the eraser to the part needing to be erased in the frame.
