The above and other aspects, features and advantages of the present disclosure will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.
Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely examples of the disclosure that may be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides an input method, including:
detecting a second operation in the process of responding to the first operation and inputting the first track by the first parameter;
if the second operation meets the first condition, determining a second parameter at least according to the second operation;
and responding to the first operation and the second operation by the second parameter, and inputting the second track to replace the input of the first track.
The input method in the embodiment of the application has the advantages that a user can automatically acquire the second parameter by adding the second operation meeting the first condition in the process of continuously inputting the first track by the first parameter, and the second track replacing the first track is matched and input based on the second operation and the second operation responded by the second parameter, so that the operation is simple and quick in the process of changing the track parameter, and the input efficiency of the user is greatly improved.
For example, when a user uses a touch display device and applies a first operation to the device, the device determines a first parameter based on the first operation and inputs a first track based on the first parameter, and during the input of the first track, i.e., while the user is not moving away from the device, the device still continues to input the first track with the first operation, the device detects that the user applies a second operation. At this time, the device may determine whether the second operation satisfies the first condition, and if so, determine the second parameter at least according to the second operation, and input the second trajectory replacing the first trajectory by using the second parameter in response to the first operation and the second operation, that is, if the user inputs the second operation using the second finger in the process of starting to input the first operation only for the first finger of the user to uninterruptedly input the first trajectory, and then the user controls the two fingers to synchronously input the first operation and the second operation to input the second trajectory, the second trajectory may be connected to the first trajectory to form two continuous trajectories, but specific parameters based on which the two continuous trajectories are formed are different.
Further, responding to the first operation and the second operation with the second parameter includes:
the second operation and the first operation form an aggregate operation, and the aggregate operation represents that the combination of the first operation and the second operation which occur at the same time is regarded as an independent third operation;
the third operation is responded with the second parameter instead of responding with the first operation with the first parameter.
That is, when the device responds to the first operation and the second operation with the second parameter, the device actually regards the first operation and the second operation as a whole and operates independently of the first operation or the set of the second operation, that is, the third operation, so that when responding to the operation instruction of the user, the device ignores the response to the first operation for inputting the first trajectory, and does not respond to the second operation alone (in this embodiment, since the second operation itself does not constitute an individual input, it does not respond to the second operation alone), and responds only to the third operation, so as to input the second trajectory based on the second parameter, and replaces the response to the first operation with the response.
For example, when a first finger of a user inputs a straight track (corresponding to a first track) on the device, a second finger simultaneously inputs a second operation on the device, the device determines a second parameter after determining that the second operation meets a first condition, then responds to a circle drawing operation input on the device by the first finger and the second finger simultaneously along the same moving track based on the second parameter, and matches and inputs a circular track (corresponding to the second track) with different parameters from the straight track based on the circle drawing operation.
Further, the second track in this embodiment has the same input attribute as the first track, wherein the input attribute includes at least one of the following:
displaying a track for increasing display content; or
The track corresponding to the already existing display content is deleted.
For example, the first trajectory is a trajectory input by a virtual brush in the device for increasing the display content, that is, a trajectory input by the brush, and the attributes of the second trajectory are the same as those of the first trajectory, and are both trajectories for increasing the display content. Or the first track is a track input by a virtual eraser in the device and used for deleting the existing display content, namely the track input by the eraser, and the second track has the same attribute as the first track and is a track used for deleting the display content. Or after the user inputs the first track through the brush pen, the virtual input tool is switched, the brush pen is switched to be the eraser, the second track is input through the eraser to erase at least part of the display content corresponding to the first track, at the moment, the attribute information of the first track is the track for increasing the display content, and the attribute information of the second track is the track for deleting the existing display content. That is, the input attribute of either the first track or the second track is to change the display content of the device, such as to add the display content, or delete the display content to reduce the attribute of the display content. When the user switches the virtual input tool, the switching operation is not unique, for example, the user inputs a double-click operation, inputs a specific pattern operation, or invokes a toolbar to manually select, and the like.
Further, in this embodiment, when determining the second parameter, that is, when determining the second parameter at least according to the second operation, the method includes:
the second parameter is determined according to a relationship between the first operation and the second operation.
That is, the first operation and the second operation have a relationship therebetween, and based on the relationship, the second parameter for matching the input second trajectory may be determined. The relationship may be, for example, a relationship between the degrees of motion correlation between the two operations, a relationship between pressures applied to the apparatus by the two operations, or a relationship between positions of the two operations, which will be described later and is adopted in the present embodiment.
Specifically, in this embodiment, the first parameter and the second parameter are both track effect parameters;
determining the second parameter from the relationship of the first operation and the second operation includes:
determining an effect parameter of the track according to the distance between the first operation position and the second operation position at the same moment;
wherein the effect parameters include at least one of: a color parameter, a size parameter, or a type parameter.
Example 1:
assuming that the effect parameter of the track is a color parameter, when the first finger and the second finger of the user input the first operation and the second operation, respectively, the device detects a distance between the first operation position and the second operation position, so as to adjust the color parameter for inputting the second track based on the distance. Specifically, when the operation attribute of the second operation is used to increase the display content, specifically, when the second trajectory is input by using the brush to increase the attribute of the display content, if the distance between the two operations is large, such as 4cm and 5cm, the display color of the display content corresponding to the input second trajectory is darker, and otherwise, if the distance is smaller, the display color of the display content corresponding to the input second trajectory is lighter. The distance between the two operations is different, and the shade of the color corresponding to the display content can be determined based on the chromaticity change of the same color, or based on different colors with different chromaticities, if the distance is larger, the display content corresponding to the second track is displayed by adopting the color of the dark color system, such as dark purple, otherwise, if the distance is smaller, the display content can be displayed by adopting the color of the light color system, such as light blue.
Example 2:
assuming that the effect parameter of the track is a size parameter, when the device detects a distance between the first operation and the second operation, for example, the input attribute of the second operation is an attribute for increasing the display content, specifically, when the first track and the second track are both input by using a brush, as shown in fig. 2 and 3, if the distance between the two operations is large, the display line corresponding to the second track may be thickened, that is, the line width of the line is changed, or, when the line corresponding to the second track is a non-solid line such as a dashed line, a dot-dash line, or the like, the large distance may also be reflected in the distance between two adjacent line segments in the dashed line and the dot-dash line, such as the distance is increased. On the contrary, if the distance is smaller, the line width of the display line can be reduced to be thinner, or the distance between the two line segments can be reduced. Of course, the line width and the spacing between line segments may also be varied. And when the input attribute of the second operation is the attribute of deleting the display content, for example, when the display content is deleted by using an eraser, the second parameter is the parameter representing the size of the eraser, when the distance between the two operations is increased, the size of the eraser is increased, otherwise, the size of the eraser is reduced.
Further, when the input attribute corresponding to the operation is to increase the display content, for example, when the user inputs a straight line on the touch area of the device through two fingers, the second parameter may match the distance between the two fingers, so that the line width of the line input and displayed based on the second parameter is the same as the distance between the two fingers. Alternatively, the setting value of the second parameter may be in a preset proportion to the distance between two fingers of the user, so that the line width of the line input and displayed based on the second parameter is greater than the distance between two fingers of the user, for example, 4 times, 8 times, etc., and the greater the distance between two fingers of the user, the greater the setting value of the corresponding second parameter is, so that the greater the width of the displayed line is. That is, the distance between the first operating position and the second operating position is positively correlated with the set value of the second parameter. The above example can be applied to the case that the device has a larger touch area and a larger display area, so that the user can significantly increase or decrease the line width of the display line based on the zoom operation of two fingers.
Preferably, when the device has a large touch area and a large display area, such as a large enough to accommodate a user attaching the entire palm to the touch area, if the user attaches the entire palm to the touch area, the device detects all touch points corresponding to the palm attachment area, determines a distance between two touch points with the farthest distance based on the touch points, and determines the second parameter based on the distance. Of course, the distance may not be calculated, and the output line may be displayed with the maximum line width.
Example 3:
assuming that the effect parameter of the track is the type parameter, in conjunction with embodiments 1 and 2, if the input operation is inputting the second track with the brush, the type of the line used for displaying the second track may be determined based on the distance between the first operation and the second operation, and the line may be a solid line if the distance is larger, and a dotted line or a dot-and-dash line if the distance is smaller, and the distance between two adjacent line segments between the dotted lines may be relatively larger, and the distance between the two line segments may be smaller as the distance increases, and the like.
Example 4:
assuming that the effect parameter of the track is a reasonable combination of any two or three of the above embodiments 1, 2, and 3, for example, taking the input attribute of the operation as an example of increasing the display content, when the distance between two operations is large, as shown in fig. 4, the display line corresponding to the second track is a solid line, the line width is large, and the color is dark, whereas if the distance is small, the display line is a dotted line or a dot-dash line, the line width is small, the color is light, and the distance between line segments is increased.
Further, in this embodiment, when the device detects that there is a second operation, it is not directly determined that the second parameter is, but needs to determine whether the second operation satisfies the first condition, which specifically includes:
and after the second operation is detected, determining that the distance between the second operation position and the first operation position meets a first threshold value for adjusting the track effect parameter.
For example, when it is detected that the distance between the first operation position and the second operation position is 2cm, the device compares the 2cm with a first threshold value, which in this embodiment is a first absolute value, such as 1cm, 2cm, etc., but may also be a numerical value interval, such as 1cm-2 cm. If the first threshold is 2cm, the comparison may determine that the second operation satisfies the first condition, and at this time, the device may determine the second parameter based on a distance between the first operation position and the second operation position. That is, at the moment when the user applies the second operation on the basis of having applied the first operation, the device may determine the second parameter based on the distance between the two operations. If the first threshold is 3cm, the distance between the two operating positions is less than the first threshold, and the device can determine that no parameter adjustment is currently required.
Further, as shown in fig. 5, when determining whether the second operation satisfies the condition, the present embodiment further includes;
determining that at least the first operating position or the second operating position has changed;
determining the relation between the distance between the first operation position and the second operation position at the same moment and a second threshold value;
determining a track effect parameter and adjusting based on the relationship, or determining a direction of the second track and determining the second track based on the direction.
This step indicates that, after the user has applied the second operation to the device and completed the comparison between the distance between the two operation positions and the first threshold, if the first operation position changes, or the second operation position changes, or both the first operation position and the second operation position change, the device may determine, in real time, the relationship between the distance between the two operation positions and the second threshold at each time, that is, at the same time, and determine, based on the relationship, the effect parameter for adjusting the second trajectory, or determine the direction of the second trajectory and determine the second trajectory based on the direction.
For example, a first finger and a second finger of a user respectively input a first operation and a second operation, when positions of the two fingers of the user relative to a Y axis in the touch area are not changed, and only a position of an X axis is changed, that is, when the two fingers move in a reverse direction along the X axis, both the two operation positions are changed, so that a distance between the two operation positions is increased, when the device detects that the distance between the two operation positions is greater than a second threshold, it can be determined that an effect parameter to be adjusted by the user, such as increasing a line width, emphasizing a color, and the like, at this time, the device adjusts a trajectory effect parameter based on the distance between the two operation positions, so that the device waits for the user to input a second trajectory based on.
When the user determines that the track effect parameters of the device have been adjusted, the device controls the two fingers to move so that the positions of the two fingers relative to the Y axis are changed, and at this time, the device acquires the distance between the two fingers, that is, the distance between the two operation positions in real time, and determines that the distance is smaller than the second threshold value, it may be determined that the track effect parameters do not need to be changed, and the display content corresponding to the second track may be displayed in a matching manner based on the current effect parameters, and at the same time, the device may determine the direction of the second track based on the moving tracks of the two operation positions, and determine the second track based on the direction and the moving tracks of the two operation positions. The second threshold in this embodiment is a second absolute value, which may be the same as or greater than the first absolute value.
Further, when the user controls the two fingers to move continuously to input the second track, the distance between the two fingers is controlled to increase, when the distance between the two fingers is increased to be the same as the second threshold, the device triggers the effect parameter adjustment at the moment, so that the effect parameter is adjusted based on the distance between the two fingers at the current moment, and the second track is continuously input based on the adjusted effect parameter. At the next moment, when the device detects that the distance between the two fingers of the user is not increased, such as can be reduced or kept unchanged, the device does not adjust the track effect parameter any more, but determines the second track direction based on the moving tracks of the two operation positions, and then continues to input the second operation based on the direction and the effect parameter adjusted at the previous moment. That is, the input of the second track and the adjustment of the track effect parameter can be performed by the device in real time and quickly, and the device can dynamically adjust the effect parameter according to the real-time situation during the process of inputting the second track, so that different paragraphs of the same track can have different display effects, and specifically refer to the contents shown in fig. 4.
The second threshold in this embodiment may be a function, i.e., the value of the second threshold varies. For example, the second threshold value at the subsequent time includes an increment of the distance between the two operation positions at the previous time and a second threshold value at the previous time, that is, the second threshold value at the subsequent time is formed by an absolute value of the increment of the distance between the operation positions at the subsequent time and the previous time and the second threshold value at the previous time. For example, assume that the distance increment b between the previous time and the next time is 0.1, and the second threshold a at the previous time is 1, both in centimeters, as follows. The second threshold is set as a function a + nb, where n is the number of times the increment b is generated between the two operating positions, as the number of times the second threshold is changed. If the initial second threshold a is 1, then n is 0, when the two operation positions are changed and an incremental change of 0.1 is generated, n is 1, at this time, the system may determine to change the track effect parameter and change the second threshold to 1.1 (and 0.9, which may be calculated according to the difference of the incremental generation directions), when the two operation positions are continuously changed and an incremental change of 0.1 is generated, n is 2, the system continuously changes the second threshold to 1.2 and determines the corresponding track effect parameter, and so on.
In practical application, the system may pre-store a corresponding table of a second threshold and a corresponding track parameter adjustment value, wherein the second threshold may be obtained by the above method. When the equipment detects that the distance between the two operation positions changes, a second threshold value can be inquired based on the corresponding table, and if a matched second threshold value is inquired, the effect parameter of the current second track is adjusted by the track parameter adjusting value corresponding to the second threshold value.
Specifically, in the correspondence table, the second threshold value may be recorded as 0.8, 0.9, 1, 1.1, 1.2 …, etc. in the table. Each type of track effect parameter, such as a parameter for adjusting the thickness of a track line, a color parameter, etc., may be set corresponding to each second threshold, and specifically, may be set to 1r, 2r, 3r, 4r, 5r …, etc., in sequence corresponding to the second threshold, where r is an adjustment coefficient, a unit adjustment amount, etc. When the device detects that the distance between the two operation positions changes for the first time, the corresponding table can be inquired, if the current distance is 1.1, the corresponding second threshold value at the current moment is 1.1, and when the distance between the two operation positions corresponding to the next moment, namely the distance between the two operation positions generates an increment again by taking the current moment as a reference, the corresponding second threshold values are the second threshold values at the front side and the rear side of the current second threshold value 1.1 in the corresponding table, namely 1 and 1.2 respectively. When the distance increment is detected again at the third moment of the equipment, the second threshold values are respectively the numerical values of the front side and the rear side of 1 in the corresponding table, namely 0.9 and 1.1, or the numerical values of the front side and the rear side of 1.2 in the corresponding table, namely 1.1 and 1.3, and so on. That is, each time the operation distance is increased, the device may query the corresponding table, and if it is determined that the current matching second threshold value exists, the device may obtain the corresponding adjustment parameter based on the second threshold value, and may predict the matching second threshold value when the next operation distance is increased to the same extent.
When the system detects that the distance between the two operation positions reaches a second threshold value, the system adjusts the effect parameters of the second track according to the corresponding parameter adjustment values. If the distance between the two operation positions does not change incrementally in the process of inputting the second track, for example, in the process of inputting the second track, the distance between the two operation positions is always 1.1, or the distance between the two operation positions is increased, but the increment is less than 0.1, the system does not adjust the parameters, but determines the input direction of the second track in real time in the input process. Therefore, the equipment can determine when to adjust the parameters in the process of inputting the second track and determine the direction of the second track based on the corresponding relation table, and the whole process is more convenient and faster.
Further, since the variation of the distance between the two fingers of the user is limited, in order to speed up the adjustment of the effect parameter of the second track, so that the user can make the display effect of the second track have obvious change only based on a fine operation, the second threshold may be defined as a condition for determining whether the increment of the distance between the two operation positions satisfies the adjustment parameter, that is, the second threshold corresponds to the distance increment. The second threshold may be specifically an n-times iteration equation based on a function f (x), where f (x) is indefinite, e.g., c x, c is a constant, and x is the second threshold adjusted last time. Or the second threshold may be set to a function xnWherein x is the second threshold adjusted last time, and n is the number of times the second threshold is changed. Based on the above equation, the distance variable for triggering the device to change the second track display effect parameter may gradually decrease, so that the user may trigger the device to change the track effect parameter even if a slight change occurs after the two fingers have been spread apart by a certain distance in the later period.
Further, this embodiment further includes:
in the process of inputting the second track, detecting that only the first operation is included at the same time;
the first operation is responded to with a first parameter.
For example, in the process of inputting the second track, the user cancels the second operation, that is, only the first operation can be detected on the touch area of the device, and if the user switches from the two-finger operation to the single-finger operation in the process of inputting the second track, the user responds to the first operation again with the first parameter, so that the user can switch the input mode at any time.
Preferably, in order to make a user clearly know a track display effect corresponding to a distance between two current operation positions when the user can change the two operation positions to adjust the track effect parameter, the present embodiment further includes:
if the second operation meets a second condition;
a preset effect is displayed, and the preset effect graph comprises the demonstrative content with the same display effect as the second track.
Wherein the second condition is equivalent to a trigger condition for triggering the device to display the demonstrative content. For example, when the user inputs the second operation and keeps the current distance between the two operation positions for more than the preset time, the display content including the same display effect as the second track, that is, the effect preview is displayed, so as to meet the requirement of the user for knowing the effect. Or the equipment can detect that the pressure of the first operation and the pressure of the second operation of the user are the same or similar, or the equipment can correspondingly display the preview effect after keeping the same value for a certain time. When the user determines to continue inputting the track based on the preview effect, the user may cancel the second operation and continue inputting the first operation in the form of a single finger, and at this time, the input track may be in an original state, i.e., a track effect state in which the first parameter responds, or may be a preview effect determined earlier, i.e., a track input in which the second parameter responds, and track content is displayed in an effect different from the initial state. That is, the user can change the display effect of the first trajectory input next by inputting the second operation.
As shown in fig. 6, an embodiment of the present application also provides an electronic device, including:
an input device for detecting an approach or contact operation;
processing means for responding to a proximity or contact operation;
wherein the input means detects the second operation in a process of the processing means inputting the first trajectory in response to the first operation with the first parameter;
if the second operation satisfies the first condition, a second parameter is determined based on at least the second operation, and the second trajectory is input to continue the input of the first trajectory in response to the first operation and the second operation with the second parameter.
In this embodiment, the input device may include a touch area and a display area, which are stacked to have a touch display function. The electronic equipment in the embodiment of the application has the advantages that a user can automatically acquire the second parameter by adding the second operation meeting the first condition in the process of continuously inputting the first track by the first parameter, and the second track replacing the first track is matched and input based on the second operation and the second operation responded by the second parameter, so that the operation is simple and fast in the process of changing the track parameter, and the input efficiency of the user is greatly improved.
For example, when a user uses a touch display device and applies a first operation based on the device, a processing device in the device determines a first parameter based on the first operation and inputs a first track based on the first parameter, and during the input of the first track, i.e., during the process that the user does not move away from the device and still touches an input device of the device with the first operation to continue inputting the first track, the processing device detects that the user applies a second operation. At this time, the processing device may determine whether the second operation satisfies the first condition, and if so, determine the second parameter at least according to the second operation, and input the second trajectory replacing the first trajectory by using the second parameter in response to the first operation and the second operation, that is, if the user inputs the second operation using the second finger in the process of starting to input the first operation only for the first finger of the user so as to uninterruptedly input the first trajectory, and then the user controls the two fingers to synchronously input the first operation and the second operation so as to input the second trajectory, then the second trajectory may be connected after the first trajectory to form a continuous two-segment trajectory, but specific parameters based on which the continuous two-segment trajectory is formed are different.
Further, the processing device, when responding to the first operation and the second operation with the second parameter, comprises:
the second operation and the first operation form an aggregate operation, and the aggregate operation represents that the combination of the first operation and the second operation which occur at the same time is regarded as an independent third operation;
the third operation is responded with the second parameter instead of responding with the first operation with the first parameter.
That is, when the processing apparatus responds to the first operation and the second operation with the second parameter, in fact, the processing apparatus regards the first operation and the second operation as a whole and operates independently of the first operation or the set of the second operations, that is, the third operation, so that when responding to the operation instruction of the user, the processing apparatus ignores the response to the first operation for inputting the first trajectory, and does not respond to the second operation alone (in this embodiment, the second operation itself does not constitute an independent input, and therefore does not respond to the second operation alone), and responds only to the third operation, so as to input the second trajectory based on the second parameter, and replaces the response to the first operation with the response.
For example, when a first finger of the user inputs a straight track (corresponding to a first track) on the input device, a second finger simultaneously inputs a second operation on the input device, the processing device determines a second parameter after determining that the second operation satisfies a first condition, then responds to a circle drawing operation input on the processing device by the first finger and the second finger simultaneously along the same moving track based on the second parameter, and matches and inputs a circular track (corresponding to a second track) with different parameters from the straight track based on the circle drawing operation.
Further, the second track in this embodiment has the same input attribute as the first track, wherein the input attribute includes at least one of the following:
displaying a track for increasing display content; or
The track corresponding to the already existing display content is deleted.
For example, the first trajectory is a trajectory input by a virtual brush in the device for increasing the display content, that is, a trajectory input by the brush, and the attributes of the second trajectory are the same as those of the first trajectory, and are both trajectories for increasing the display content. Or the first track is a track input by a virtual eraser in the device and used for deleting the existing display content, namely the track input by the eraser, and the second track has the same attribute as the first track and is a track used for deleting the display content. Or after the user inputs the first track through the brush pen, the virtual input tool is switched, the brush pen is switched to be the eraser, the second track is input through the eraser to erase at least part of the display content corresponding to the first track, at the moment, the attribute information of the first track is the track for increasing the display content, and the attribute information of the second track is the track for deleting the existing display content. That is, the input attribute of either the first track or the second track is to change the display content of the device, such as to add the display content, or delete the display content to reduce the attribute of the display content. When the user switches the virtual input tool, the switching operation is not unique, for example, the user inputs a double-click operation, inputs a specific pattern operation, or invokes a toolbar to manually select, and the like.
Further, the processing device in this embodiment, when determining the second parameter, i.e. when determining the second parameter at least according to the second operation, includes:
the second parameter is determined according to a relationship between the first operation and the second operation.
That is, the first operation and the second operation have a relationship therebetween, and based on the relationship, the second parameter for matching the input second trajectory may be determined. The relationship may be, for example, a relationship between the degrees of motion correlation between the two operations, a relationship between pressures applied to the input device by the two operations, or a positional relationship between the two operations, which will be described later and is adopted in the present embodiment.
Specifically, in this embodiment, the first parameter and the second parameter are both track effect parameters;
determining the second parameter from the relationship of the first operation and the second operation includes:
determining an effect parameter of the track according to the distance between the first operation position and the second operation position at the same moment;
wherein the effect parameters include at least one of: a color parameter, a size parameter, or a type parameter.
Example 1:
assuming that the effect parameter of the track is a color parameter, when the first finger and the second finger of the user input the first operation and the second operation, respectively, the processing device detects a distance between the first operation position and the second operation position, so as to adjust the color parameter for inputting the second track based on the distance. Specifically, when the operation attribute of the second operation is used to increase the display content, specifically, when the second trajectory is input by using the brush to increase the attribute of the display content, if the distance between the two operations is large, such as 4cm and 5cm, the display color of the display content corresponding to the input second trajectory is darker, and otherwise, if the distance is smaller, the display color of the display content corresponding to the input second trajectory is lighter. The distance between the two operations is different, and the shade of the color corresponding to the display content can be determined based on the chromaticity change of the same color, or based on different colors with different chromaticities, if the distance is larger, the display content corresponding to the second track is displayed by adopting the color of the dark color system, such as dark purple, otherwise, if the distance is smaller, the display content can be displayed by adopting the color of the light color system, such as light blue.
Example 2:
assuming that the effect parameter of the track is a size parameter, when the processing device detects the distance between the first operation and the second operation, for example, the input attribute of the second operation is an attribute for increasing the display content, specifically, when the first track and the second track are both input by using a brush, as shown in fig. 2 and 3, if the distance between the two operations is large, the display line corresponding to the second track may be thickened, that is, the line width of the line may be changed, or, when the line corresponding to the second track is a non-solid line such as a dashed line, a dot-dash line, or the like, the large distance may also be reflected in the distance between two adjacent line segments in the dashed line and the dot-dash line, for example, the distance is increased. On the contrary, if the distance is smaller, the line width of the display line can be reduced to be thinner, or the distance between the two line segments can be reduced. Of course, the line width and the spacing between line segments may also be varied. And when the input attribute of the second operation is the attribute of deleting the display content, for example, when the display content is deleted by using an eraser, the second parameter is the parameter representing the size of the eraser, when the distance between the two operations is increased, the size of the eraser is increased, otherwise, the size of the eraser is reduced.
Further, when the input attribute corresponding to the operation is to increase the display content, for example, when the user inputs a straight line on the touch area of the device through two fingers, the second parameter may match the distance between the two fingers, so that the line width of the line input and displayed based on the second parameter is the same as the distance between the two fingers. Alternatively, the setting value of the second parameter may be in a preset proportion to the distance between two fingers of the user, so that the line width of the line input and displayed based on the second parameter is greater than the distance between two fingers of the user, for example, 4 times, 8 times, etc., and the greater the distance between two fingers of the user, the greater the setting value of the corresponding second parameter is, so that the greater the width of the displayed line is. That is, the distance between the first operating position and the second operating position is positively correlated with the set value of the second parameter. The above example can be applied to the case that the device has a larger touch area and a larger display area, so that the user can significantly increase or decrease the line width of the display line based on the zoom operation of two fingers.
Preferably, when the device has a larger touch area and a larger display area, such as a large enough to accommodate a user attaching the entire palm to the touch area, if the user attaches the entire palm to the touch area, the processing device detects all touch points corresponding to the palm attachment area, determines a distance between two touch points with the farthest distance based on the touch points, and determines the second parameter based on the distance. Of course, the distance may not be calculated, and the output line may be displayed with the maximum line width.
Example 3:
assuming that the effect parameter of the track is the type parameter, in conjunction with embodiments 1 and 2, if the input operation is inputting the second track with the brush, the type of the line used for displaying the second track may be determined based on the distance between the first operation and the second operation, and the line may be a solid line if the distance is larger, and a dotted line or a dot-and-dash line if the distance is smaller, and the distance between two adjacent line segments between the dotted lines may be relatively larger, and the distance between the two line segments may be smaller as the distance increases, and the like.
Example 4:
assuming that the effect parameter of the track is a reasonable combination of any two or three of the above embodiments 1, 2, and 3, for example, taking the input attribute of the operation as an example of increasing the display content, when the distance between two operations is large, as shown in fig. 4, the display line corresponding to the second track is a solid line, the line width is large, and the color is dark, whereas if the distance is small, the display line is a dotted line or a dot-dash line, the line width is small, the color is light, and the distance between line segments is increased.
Further, in this embodiment, when the processing device detects that there is a second operation, it is not directly determined that the second parameter is, but needs to determine whether the second operation satisfies the first condition, which specifically includes:
and after the second operation is detected, determining that the distance between the second operation position and the first operation position meets a first threshold value for adjusting the track effect parameter.
For example, when it is detected that the distance between the first operation position and the second operation position is 2cm, the processing device compares the 2cm with a first threshold value, which in this embodiment is a first absolute value, such as 1cm, 2cm, etc., but may also be a numerical value interval, such as 1cm-2 cm. If the first threshold is 2cm, the comparison may determine that the second operation satisfies the first condition, and the processing device may determine the second parameter based on a distance between the first operation position and the second operation position. That is, when the user applies the second operation on the basis of having applied the first operation, the processing device may determine the second parameter based on the distance between the two operations. If the first threshold is 3cm, the distance between the two operation positions is smaller than the first threshold, and the processing device can determine that parameter adjustment is not required to be started currently.
Further, as shown in fig. 5, the processing means, when determining whether the second operation satisfies the condition, further includes;
determining that at least the first operating position or the second operating position has changed;
determining the relation between the distance between the first operation position and the second operation position at the same moment and a second threshold value;
determining a track effect parameter and adjusting based on the relationship, or determining a direction of the second track and determining the second track based on the direction.
This step indicates that, after the user has applied the second operation to the device and completed the comparison between the distance between the two operation positions and the first threshold, if the first operation position changes, or the second operation position changes, or both the first operation position and the second operation position change, the processing device may determine, in real time, the relationship between the distance between the two operation positions and the second threshold at each time, that is, at the same time, and determine, based on the relationship, the effect parameter for adjusting the second trajectory, or determine the direction of the second trajectory and determine the second trajectory based on the direction.
For example, the first finger and the second finger of the user input the first operation and the second operation respectively, when the positions of the two fingers of the user relative to the Y axis in the touch area are not changed, and only the position of the X axis is changed, that is, when the two fingers move in the opposite direction along the X axis, both the two operation positions are changed, so that the distance between the two operation positions is increased, and when the processing device detects that the distance between the two operation positions is greater than the second threshold, it can be determined that the user wants to adjust the effect parameter, such as increasing the line width, emphasizing the color, and the like, at this time, the processing device adjusts the track effect parameter based on the distance between the two operation positions, so that the user is waited to input the second track based on.
When the user determines that the track effect parameters are adjusted by the processing device, the two fingers are controlled to move so that the positions of the two fingers relative to the Y axis are changed, at the moment, the processing device collects the distance between the two fingers, namely the distance between the two operation positions in real time, and determines that the distance is smaller than a second threshold value, the processing device can determine that the track effect parameters do not need to be changed, can match and display the display content corresponding to the second track based on the current effect parameters, and meanwhile, the processing device can determine the direction of the second track based on the moving tracks of the two operation positions and determine the second track based on the direction and the moving tracks of the two operation positions. The second threshold in this embodiment is a second absolute value, which may be the same as or greater than the first absolute value.
Further, when the user controls the two fingers to move continuously to input the second track, the distance between the two fingers is controlled to increase, and when the distance between the two fingers is increased to be the same as the second threshold, the processing device triggers the effect parameter adjustment at the moment, so that the effect parameter is adjusted based on the distance between the two fingers at the current moment, and the second track is continuously input based on the adjusted effect parameter. When the processing device detects that the distance between the two fingers of the user is not increased at the next moment, if the distance can be reduced or kept unchanged, the processing device does not adjust the track effect parameter any more, determines the second track direction based on the moving tracks of the two operation positions, and then continues to input the second operation based on the direction and the effect parameter adjusted at the previous moment. That is, the input of the second track and the adjustment of the track effect parameter can be performed by the device in real time and quickly, and the processing device can dynamically adjust the effect parameter according to the real-time situation during the process of inputting the second track, so that different paragraphs of the same track can have different display effects, and specifically refer to the contents shown in fig. 4.
The second threshold in this embodiment may be a function, i.e., the value of the second threshold varies. For example, the second threshold value at the subsequent time includes an increment of the distance between the two operation positions at the previous time and a second threshold value at the previous time, that is, the second threshold value at the subsequent time is formed by an absolute value of the increment of the distance between the operation positions at the subsequent time and the previous time and the second threshold value at the previous time. For example, assume that the distance increment b between the previous time and the next time is 0.1, and the second threshold a at the previous time is 1, both in centimeters, as follows. The second threshold is set as a function a + nb, where n is the number of times the increment b is generated between the two operating positions, as the number of times the second threshold is changed. If the initial second threshold a is 1, then n is 0, when the two operation positions are changed and an incremental change of 0.1 is generated, n is 1, at this time, the system may determine to change the track effect parameter and change the second threshold to 1.1 (and 0.9, which may be calculated according to the difference of the incremental generation directions), when the two operation positions are continuously changed and an incremental change of 0.1 is generated, n is 2, the system continuously changes the second threshold to 1.2 and determines the corresponding track effect parameter, and so on.
In practical application, the system may pre-store a corresponding table of a second threshold and a corresponding track parameter adjustment value, wherein the second threshold may be obtained by the above method. When the equipment detects that the distance between the two operation positions changes, a second threshold value can be inquired based on the corresponding table, and if a matched second threshold value is inquired, the effect parameter of the current second track is adjusted by the track parameter adjusting value corresponding to the second threshold value.
Specifically, in the correspondence table, the second threshold value may be recorded as 0.8, 0.9, 1, 1.1, 1.2 …, etc. in the table. Each type of track effect parameter, such as a parameter for adjusting the thickness of a track line, a color parameter, etc., may be set corresponding to each second threshold, and specifically, may be set to 1r, 2r, 3r, 4r, 5r …, etc., in sequence corresponding to the second threshold, where r is an adjustment coefficient, a unit adjustment amount, etc. When the device detects that the distance between the two operation positions changes for the first time, the corresponding table can be inquired, if the current distance is 1.1, the corresponding second threshold value at the current moment is 1.1, and when the distance between the two operation positions corresponding to the next moment, namely the distance between the two operation positions generates an increment again by taking the current moment as a reference, the corresponding second threshold values are the second threshold values at the front side and the rear side of the current second threshold value 1.1 in the corresponding table, namely 1 and 1.2 respectively. When the distance increment is detected again at the third moment of the equipment, the second threshold values are respectively the numerical values of the front side and the rear side of 1 in the corresponding table, namely 0.9 and 1.1, or the numerical values of the front side and the rear side of 1.2 in the corresponding table, namely 1.1 and 1.3, and so on. That is, each time the operation distance is increased, the device may query the corresponding table, and if it is determined that the current matching second threshold value exists, the device may obtain the corresponding adjustment parameter based on the second threshold value, and may predict the matching second threshold value when the next operation distance is increased to the same extent.
When the system detects that the distance between the two operation positions reaches a second threshold value, the system adjusts the effect parameters of the second track according to the corresponding parameter adjustment values. If the distance between the two operation positions does not change incrementally in the process of inputting the second track, for example, in the process of inputting the second track, the distance between the two operation positions is always 1.1, or the distance between the two operation positions is increased, but the increment is less than 0.1, the system does not adjust the parameters, but determines the input direction of the second track in real time in the input process. Therefore, the equipment can determine when to adjust the parameters in the process of inputting the second track and determine the direction of the second track based on the corresponding relation table, and the whole process is more convenient and faster.
Further, since the variation of the distance between the two fingers of the user is limited, in order to speed up the adjustment of the effect parameter of the second track, so that the user can make the display effect of the second track have obvious change only based on a fine operation, the second threshold may be defined as a condition for determining whether the increment of the distance between the two operation positions satisfies the adjustment parameter, that is, the second threshold corresponds to the distance increment. The second threshold may be specifically an n-times iteration equation based on a function f (x), where f (x) is indefinite, e.g., c x, c is a constant, and x is the second threshold adjusted last time. Or the second threshold may be set to a function xnWherein x is the second threshold adjusted last time, and n is the number of times the second threshold is changed. Based on the above equation, the distance variable for triggering the device to change the second track display effect parameter may gradually decrease, so that the user may trigger the device to change the track effect parameter even if a slight change occurs after the two fingers have been spread apart by a certain distance in the later period.
Further, the processing apparatus in this embodiment is further configured to:
in the process of inputting the second track, detecting that only the first operation is included at the same time;
the first operation is responded to with a first parameter.
For example, in the process of inputting the second track, the user cancels the second operation, that is, only the first operation can be detected on the touch area of the device, and if the user switches from the two-finger operation to the single-finger operation in the process of inputting the second track, the user responds to the first operation again with the first parameter, so that the user can switch the input mode at any time.
Preferably, in order to make the user clearly know the track display effect corresponding to the distance between the two current operation positions when changing the two operation positions to adjust the track effect parameter, the processing device in this embodiment is further configured to:
if the second operation meets a second condition;
a preset effect is displayed, and the preset effect graph comprises the demonstrative content with the same display effect as the second track.
The second condition corresponds to a trigger condition for triggering the processing device to control the display area of the input device to display the indicative content. For example, when the user inputs the second operation and keeps the current distance between the two operation positions for more than the preset time, the display content including the same display effect as the second track, that is, the effect preview is displayed, so as to meet the requirement of the user for knowing the effect. Or, the processing device may detect that the first operation and the second operation of the user have the same or similar pressure, or may correspondingly display the preview effect after keeping the same value for a certain time. When the user determines to continue inputting the track based on the preview effect, the user may cancel the second operation and continue inputting the first operation in the form of a single finger, and at this time, the input track may be in an original state, i.e., a track effect state in which the first parameter responds, or may be a preview effect determined earlier, i.e., a track input in which the second parameter responds, and track content is displayed in an effect different from the initial state. That is, the user can change the display effect of the first trajectory input next by inputting the second operation.
It can be clearly understood by those skilled in the art that, for convenience and brevity of description, the electronic device to which the data processing method described above is applied may refer to the corresponding description in the foregoing product embodiments, and details are not repeated herein.
