Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A method, an apparatus, an electronic device, and a computer-readable storage medium for processing a touch screen scribing operation according to embodiments of the present invention are described below with reference to the accompanying drawings.
FIG. 1 is a flow diagram of a method of processing a touch screen scribing operation according to one embodiment of the invention. The method for processing the scribing operation of the touch screen according to the embodiment of the invention can be applied to a processing device for the scribing operation of the touch screen according to the embodiment of the invention, and the processing device can be configured on an electronic device. Wherein the electronic device may be a mobile terminal. For example, the mobile terminal may be a hardware device having various operating systems, such as a mobile phone, a tablet computer, a personal digital assistant, and the like.
As shown in fig. 1, the processing method of the scribing operation of the touch screen may include:
and S110, detecting whether the touch screen is in a line drawing state at present.
As an example, it may be determined whether an actual report point is continuously received, and if so, it is detected that the touch screen is currently in the line drawing state, where the actual report point is used to indicate a touch point scanned according to a preset scanning frequency. That is, whether a touch point is scanned in a plurality of consecutive scanning periods may be determined, and if so, it may be determined that the touch screen is currently in the scribing state. The line drawing state can be understood as a state of the touch screen when a user performs line drawing operation on the touch screen.
It should be noted that, in the embodiment of the present invention, the touch screen may be a capacitive touch screen. Alternatively, whether a touch point exists on the touch screen can be determined by detecting whether capacitance change occurs on the touch screen. That is, when it is detected that the capacitance of a certain touch unit on the touch screen changes, it can be determined that a touch point currently exists on the touch screen, for example, a coordinate point corresponding to the touch unit is touched by a user.
Therefore, when the user performs the scribing operation on the touch screen, the capacitance of the touch unit on the touch screen can be greatly changed, at this time, if the touch screen IC can scan the touch screen according to the preset scanning frequency and scan the coordinate point corresponding to the touch unit, the coordinate point can be reported, so that the actual report point scanned this time can be obtained, and the actual report point is the report point generated when the user performs the scribing operation on the touch screen this time. Therefore, the embodiment of the invention can detect whether the touch screen is in the scribing state or not by using the principle.
And S120, when the touch screen is detected to be in a scribing state at present, acquiring coordinates of the last N actual report points newly generated in the current scribing operation process, wherein N is a positive integer greater than 2.
S130, generating the coordinates of at least one simulated report point according to the coordinates of the first N actual report points.
Optionally, a curve equation is established according to the coordinates of the first N actual report points, and the coordinates of at least one simulated report point among the first N actual report points are generated according to the curve equation and the coordinates of the first N actual report points.
For example, assuming that N is 3, that is, when it is detected that the touch screen is currently in the line drawing state, coordinates of the first three actual report points newly generated during the current line drawing operation may be obtained, and a curve equation of two-dimensional and two-dimensional (for example, y ═ ax ^2+ bx + c) is established according to the coordinates of the first three actual report points, and then, coordinates of simulated report points among the first three actual report points may be calculated according to the curve equation and the coordinates of the first three actual report points.
As an example, the specific implementation process of generating the coordinates of at least one simulated report point between the first N actual report points according to the curve equation and the coordinates of the first N actual report points may be as follows: and calculating the added value between the abscissa or the ordinate in the first N actual report points, determining the abscissa or the ordinate of at least one simulated report point between two adjacent actual report points in the first N actual report points according to the added value, and generating the coordinate of the at least one simulated report point according to the abscissa or the ordinate of the at least one simulated report point and the curve equation.
For example, assuming that N is 3, the abscissa "10", "20" and "30" of the first three actual report points (point 1, point 2 and point 3) is taken as an example, and the increment between the abscissas of the first three actual report points is 10, at this time, the abscissa of the simulated report point between two adjacent actual report points in the first three actual report points can be determined according to the increment, for example, the abscissa of the simulated report point 1 'between point 1 and point 2 is "15", and the abscissa of the simulated report point 2' between point 2 and point 3 is "25", and then, the ordinate of the two simulated report points can be calculated according to the abscissas of the two simulated report points and the curve equation, so as to obtain the coordinate values of the two simulated report points. It is understood that the number of the simulated time points between two adjacent actual time points may be one or more, and may be set according to actual requirements, and the present invention is not limited in particular.
As another example, the specific implementation process of generating the coordinates of at least one simulated report point between the first N actual report points according to the curve equation and the coordinates of the first N actual report points may be as follows: and generating the abscissa or ordinate of at least one simulated report point between two adjacent actual report points in the first N actual report points randomly according to the abscissa or ordinate of the first N actual report points, and generating the coordinate of the at least one simulated report point according to the abscissa or ordinate of the at least one simulated report point and the curve equation.
For example, assuming that N is 3, the abscissa of the previous three actual report points (point 1, point 2, and point 3) "10", "20", and "30" are taken as examples, at this time, the abscissa of the simulated report point between two adjacent actual report points in the previous three actual report points may be randomly generated, for example, the abscissa of the simulated report point 1 'between the randomly generated point 1 and point 2 is "8", the abscissa of the simulated report point 2' between the randomly generated point 2 and point 3 is "12", and then, the ordinate of the two simulated report points may be calculated according to the abscissa of the two simulated report points and the curve equation, so as to obtain the coordinate values of the two simulated report points. It is understood that the number of the simulated time points between two adjacent actual time points may be one or more, and may be set according to actual requirements, and the present invention is not limited in particular.
And S140, generating a marking track of the current marking operation according to the coordinates of the actual marking point and the coordinates of the simulated marking point generated in the current marking operation process.
Optionally, in the process that the touch screen is in the scribing state, that is, in the process that the user performs the scribing operation currently, the actual report point generated by the touch screen in the current scribing operation process and the generated simulated report point may be connected and displayed, and the scribing trajectory of the current scribing operation may be obtained.
For example, as shown in fig. 2(a), it is assumed that the solid line trace is the actual scribing path of the user on the touch screen, and the dashed line trace is the scribing path displayed by obtaining the actual report point, and obviously, the dashed line trace of the dashed line does not truly reflect the actual scribing path of the user. Therefore, the embodiment of the invention simulates other positions on the scribing track by using the known actual positions of the report points, so that the curve is more accurate. As shown in fig. 2(b), a simulated report point (point 1 ', point 2', point 3 ', and point 4') is generated by using a known actual report point (point 1, point 2, point 3, point 4, and point 5), so that a more accurate scribing track can be obtained by using the known actual report point and the generated simulated report point, and the obtained scribing track can reflect the actual scribing path more truly.
According to the processing method of the touch screen scribing operation, when the touch screen is detected to be in the scribing state at present, the coordinates of the first N newly-generated actual report points in the current scribing operation process are obtained, the coordinates of at least one simulated report point are generated according to the coordinates of the first N actual report points, and the scribing track of the current scribing operation is generated according to the coordinates of the actual report points and the coordinates of the simulated report points generated in the current scribing operation process. The method comprises the steps of simulating other positions in a marking track by using known actual point reporting coordinates, generating the marking track according to the known actual point reporting coordinates and the coordinates of the other positions, enabling a finally obtained curve to be more accurate, reflecting a path of actual marking more truly, and avoiding the need of calculating too high point reporting frequency of a touch screen in the whole process, so that the point reporting rate of the touch screen can be reduced, and the power consumption of the touch screen is greatly reduced.
In order to improve the usability and feasibility of the present invention, optionally, in an embodiment of the present invention, before obtaining the coordinates of the first N newly generated actual report points during the current scribing operation, as shown in fig. 3, on the basis of fig. 1, the processing method of the touch screen scribing operation may further include:
s310, judging whether the number of all the actual report points generated in the currently received line drawing operation process is larger than or equal to a preset threshold value. Wherein, the preset threshold may be 3.
Optionally, when the user performs a line drawing operation on the touch screen, so that the touch screen is in a line drawing state, the touch screen IC may continuously receive touch points (i.e., actual report points) scanned according to a preset scanning frequency, at this time, it needs to be determined whether the number of currently received actual report points can satisfy a condition for establishing a curve equation, for example, it needs to be determined whether the number of currently received actual report points is greater than or equal to 3.
And S320, if not, generating the scribing track of the current scribing operation according to all the currently received actual report points generated in the current scribing operation process.
That is, when it is determined that the number of all actual report points generated in the currently received current scribing operation process is smaller than the preset threshold, for example, the number is smaller than 3, it is determined that a curve equation cannot be fitted to all currently received actual report points, and at this time, all currently received actual report points generated in the currently received current scribing operation process may be connected and displayed to obtain a scribing trajectory of the current scribing operation.
Optionally, in an embodiment of the present invention, when the number is greater than or equal to the preset threshold, the step of obtaining the coordinates of the first N latest actual report points generated in the current scribing operation process is performed, that is, the step S120 is performed. That is, when it is determined that the number of all actual report points generated in the currently received current scribing operation process is greater than or equal to the preset threshold, for example, the number is 3, it indicates that a curve equation can be established for all currently received actual report points, at this time, coordinates of the first 3 actual report points newly generated in the current scribing operation process can be obtained, a curve equation is established according to the coordinates of the first 3 actual report points, and a simulated report point can be generated according to the curve equation and the coordinates of the first 3 actual report points. Therefore, the scribing track is generated through the known coordinates of the actual report point and the coordinates of the simulated report point, so that the finally obtained curve is more accurate, and the actual scribing path can be reflected more truly.
In order that those skilled in the art will be able to more clearly understand the present invention, the following description will be given by way of example.
For example, as shown in fig. 4, the touch screen IC may determine whether a new actual hit is currently received in real time (S410). When it is determined that a new actual hit is currently received, it is detected whether the touch screen is currently in a line drawing state by determining whether the actual hit is continuously received (S420). If it is determined that the actual report points are not continuously received currently, for example, the touch points are scanned in the previous scanning period but the touch points are not scanned in the current scanning period, the actual report points are not continuously received, and it may be considered that the user may perform a click operation on the touch screen at this time. If the actual report points are continuously received, the touch screen can be judged to be in a line drawing state currently, at this time, coordinates of the first three actual report points which are newly generated in the current line drawing operation process can be obtained, a curve equation is established according to the coordinates of the first three actual report points, and coordinates of the simulated report points are calculated according to the curve equation and the coordinates of the first three actual report points (S430). Finally, the actual report points generated by the touch screen in the current scribing operation process and the generated simulation report points are connected and displayed, and the scribing track of the current scribing operation can be obtained (S440).
For example, taking the scribing trace shown in fig. 2(b) as an example, the scribing trace can be obtained by using the embodiment of the present invention, and the specific implementation steps are as follows: when the touch screen IC receives the coordinate position of an actual report point 'point 1', the coordinate position can be directly displayed, when the coordinate position of the actual report point 'point 2' is received, the coordinate position is not displayed at first, whether a touch point is scanned in the next scanning period (namely whether the actual report point reported in the next scanning period can be received) is judged, if yes, when the coordinate of the actual report point 'point 3' is received, a function equation expression y ^ ax ^2+ bx + c is established according to the coordinates of the point 1, the point 2 and the point 3, the coordinates of a simulated report point 'point 1' ″, the 'point 2' ″, are calculated according to the function equation expression, and the coordinates of the point 1 ', the point 2' and the point 3 are all displayed to obtain a curve; similarly, when the coordinate of the actual report point "point 4" is received, the simulated report point "point 3 '" is calculated according to the coordinates of the actual report point "point 2", "point 3" and "point 4", then the point 3' and the point 4 are displayed, and so on, and the scribing track of the current scribing operation can be obtained. As shown in fig. 2(b), the point 1 ', the point 2', the point 3 'and the point 4' are simulated coordinate points, and the scribing trajectory can be made more complete by these coordinate points. Therefore, other positions of the drawn line are simulated by using the known report point positions, so that the curve is more accurate.
