[0066] Figure 1 A flowchart illustrating a touchscreen trajectory optimization method according to an embodiment of the present disclosure is shown. Figure 1 As shown, the touch screen trajectory optimization method of this disclosure embodiment may include the following steps S10-S40.

[0067] Step S10: Obtain N original coordinate points generated by the user's interaction with the touch screen based on the sampling frequency.

[0068] In one possible implementation, during user interaction with the touchscreen using a finger, stylus, or other touch-screen medium, the original coordinate points can be obtained by scanning the user's position on the touchscreen using an electronic device. Specifically, the electronic device can sample the original coordinate points according to a preset sampling frequency; that is, it repeatedly detects and acquires the position of the user's finger or stylus on the touchscreen at a preset sampling frequency to obtain the corresponding original coordinate points. Optionally, since the electronic device acquires N original coordinate points sequentially at a preset sampling frequency, each acquired original coordinate point has a temporal order.

[0069] Step S20: Determine the number of processing steps based on the preset transmission frequency and the sampling frequency.

[0070] In one possible implementation, since the sampling frequency is typically low, the touchscreen curve drawn directly from the original coordinate points obtained at the sampling frequency will exhibit unnatural effects such as jagged edges. Therefore, to improve the smoothness of the user's touchscreen curve, a transmission frequency higher than the sampling frequency can be preset. Multiple original coordinate points with an acquisition time interval equal to the sampling frequency are processed to obtain multiple processed coordinate points with an time interval equal to the transmission frequency. A smooth and natural touchscreen trajectory is then drawn based on these processed coordinate points. Optionally, the preset transmission frequency is twice the preset sampling frequency. m The multiple, where m can be 0 or any positive integer.

[0071] Optionally, the electronic device can determine the number of processing operations for each original coordinate point based on a preset transmission frequency and a preset sampling frequency, so as to obtain multiple processed coordinate points that satisfy the transmission frequency by performing the corresponding number of processing operations on the original coordinate points. The electronic device can determine the number of processing operations based on the ratio of the transmission frequency to the sampling frequency. For example, a mapping table between the ratio and the number of processing operations can be preset in the electronic device to directly determine the number of processing operations based on the ratio. When the transmission frequency is twice the sampling frequency, the number of processing operations can be determined to be 1; when the transmission frequency is four times the sampling frequency, the number of processing operations can be determined to be 3.

[0072] Step S30: For the obtained nth original coordinate point, take the (n-2)th original coordinate point, the (n-1)th original coordinate point and the nth original coordinate point as initial inputs, and perform the processing operation a certain number of times to obtain at least two processed coordinate points corresponding to the nth original coordinate point.

[0073] In one possible implementation, after determining the number of processing iterations, the electronic device sequentially processes each acquired original coordinate point, starting from the third original coordinate point, a certain number of times, to obtain at least two corresponding processed coordinate points to replace the original coordinate points for uploading. Before processing each original coordinate point, the two preceding original coordinate points are determined, using these three consecutive original coordinate points as initial inputs for multiple processing iterations to obtain the processed coordinate point of the last acquired original coordinate point. That is, when determining the processed coordinate point corresponding to the nth original coordinate point, the (n-2)th, (n-1)th, and nth original coordinate points can be used as initial inputs, and a certain number of processing iterations can be performed to obtain at least two processed coordinate points corresponding to the nth original coordinate point, where n is any integer greater than or equal to 3 and less than or equal to N.

[0074] Optionally, each processing step can determine two processing coordinate points. This process may include determining a first coordinate point, a second coordinate point, and a third coordinate point for the current processing step. Then, the sine value of the angle between the first line connecting the first and second coordinate points and the second line connecting the second and third coordinate points is calculated. Based on the sine value and the first, second, and third coordinate points, the corresponding first and second processing coordinate points are calculated.

[0075] Furthermore, the first, second, and third coordinate points determined in each calculation process are different. For example, in the first calculation process, the (n-2)th initial input coordinate point can be used as the first coordinate point, the (n-1)th initial coordinate point as the second coordinate point, and the nth initial coordinate point as the third coordinate point. In other calculation processes besides the first calculation process, the three points already determined in sequence can be used as the first, second, and third coordinate points needed for this operation. For example, in the second calculation process, the first processing coordinate point determined in the first calculation process for the (n-1)th initial coordinate point can be used as the first coordinate point, the second processing coordinate point determined in the first calculation process for the (n-1)th initial coordinate point can be used as the second coordinate point, and the first processing coordinate point determined in the first calculation process for the nth initial coordinate point can be used as the third coordinate point. In the third calculation process, the second processed coordinate point determined by the (n-1)th original coordinate point in the first calculation process can be identified as the first coordinate point, the first processed coordinate point determined by the nth original coordinate point in the first calculation process can be identified as the second coordinate point, and the second processed coordinate point determined by the nth original coordinate point in the first calculation process can be identified as the third coordinate point.

[0076] Figure 2 A schematic diagram illustrating an original coordinate point and a processed coordinate point according to an embodiment of the present disclosure is shown. Figure 2As shown, the electronic device acquires the original coordinate points P1, P2, and P3 sequentially. When a single operation is needed to determine the corresponding processed coordinate point P3, P1 can be used as the first coordinate point, P2 as the second coordinate point, and P3 as the third coordinate point, resulting in the corresponding first processed coordinate point Q3-1 and second processed coordinate point Q3-2. When a third operation is needed to determine the corresponding processed coordinate point P3, in the first operation, P1 can be used as the first coordinate point, P2 as the second coordinate point, and P3 as the third coordinate point, resulting in the corresponding first processed coordinate point Q3-1 and second processed coordinate point Q3-2. In the second operation, the first processed coordinate point Q2-1 determined in the first operation for the previous original coordinate point P2 can be identified as the first coordinate point, and the second processed coordinate point Q2-2 determined in the first operation for P2 can be identified as the second coordinate point. Finally, the first processed coordinate point Q3-1 determined in the first operation for the original coordinate point P3 can be identified as the third coordinate point. In the third calculation process, the second processing coordinate point Q2-2 determined by the original coordinate point P2 in the first calculation process can be determined as the first coordinate point, the first processing coordinate point Q3-1 determined by the original coordinate point P3 in the first calculation process can be determined as the second coordinate point, and the second processing coordinate point Q3-2 determined by the original coordinate point P3 in the first calculation process can be determined as the third coordinate point.

[0077] Optionally, in each calculation process, after the electronic device determines the first coordinate point, the second coordinate point, and the third coordinate point, it can determine the sine value of the angle between the first line formed by the first coordinate point and the second coordinate point and the second line formed by the second coordinate point and the third coordinate point, based on the coordinate values ​​of each coordinate point. Specifically, when the coordinates of the first, second, and third coordinate points are (x1, y1), (x2, y2), and (x3, y3), respectively, the cosine value of the angle α between the first and second lines can be calculated first using formula (1).

[0078]

[0079] Furthermore, after obtaining the cosine value of the included angle α, the sine value of the included angle α between the first and second connecting lines can be calculated.

[0080] In one possible implementation, after calculating the sine value of the angle between the first and second connecting lines, the electronic device can calculate the first and second processing coordinate points based on the sine value and the coordinates of the first, second, and third coordinate points during the current calculation process. Optionally, the first and second processing coordinate points can be determined first based on the sine value sin α. The first coordinate parameter, The second coordinate parameter is used. The product of the first coordinate parameter and the first coordinate point is then calculated, and the sum of this product and the product of the second coordinate parameter and the second point is used to obtain the first processed coordinate point. The product of the first coordinate parameter and the second point is then calculated, and the sum of this product and the product of the second coordinate parameter and the third point is used to obtain the second processed coordinate point.

[0081] For example, when the coordinates of the first, second, and third coordinate points are (x1, y1), (x2, y2), and (x3, y3), respectively, the coordinates (x1, y1), (x2, y2), and (x3, y3) of the first processing coordinate point can be calculated using formulas (2) and (3), respectively. Q3-1 ,y Q3-1 ) and the coordinates of the second processed coordinate point (x) Q3-2 ,y Q3-2 ).

[0082]

[0083]

[0084] In one possible implementation, the electronic device performs multiple calculations on the nth original coordinate point, obtaining two processed coordinate points with each calculation. The processed coordinate point corresponding to the nth original coordinate point can be determined from the multiple processed coordinate points obtained from the multiple calculations according to a preset rule. For example, the processed coordinate point corresponding to the nth original coordinate point can be determined to include the first and second processed coordinate points obtained from the last i processing steps, where i is obtained by calculating the ratio of the transmission frequency to the sampling frequency and dividing by 2. That is, when the ratio of the transmission frequency to the sampling frequency is 2, the first and second processed coordinate points obtained from the first processing step are directly determined as the processed coordinate points corresponding to the nth original coordinate point. When the ratio of the transmission frequency to the sampling frequency is 4, the first and second processed coordinate points obtained from the second and third processing steps are directly determined as the processed coordinate points corresponding to the nth original coordinate point.

[0085] Step S40: Upload at least two corresponding processed coordinate points as replacement coordinate points for the nth original coordinate point.

[0086] In one possible implementation, after the electronic device sequentially determines the nth original coordinate point and calculates at least two corresponding processed coordinate points, it can upload these at least two processed coordinate points as replacement coordinate points for the nth original coordinate point. The processed coordinate points corresponding to the nth original coordinate point can be uploaded in a preset order, which can be sorted according to the processing order of the coordinate points. In each processing operation, the first processed coordinate point is uploaded first, followed by the second processed coordinate point. Optionally, the upload frequency of each processed coordinate point is the transmission frequency.

[0087] Furthermore, electronic devices or other receiving devices that process coordinates can draw accurate and smooth touch screen trajectories based on the processing coordinates corresponding to each original coordinate point.

[0088] Based on the above technical features, the embodiments of this disclosure can determine the number of processing steps by the sending frequency and sampling frequency of the touch screen, and process the original coordinate points sequentially according to the determined number of processing steps to obtain the corresponding processed coordinate points and upload them at the sending frequency. This can ensure that the interval between the uploaded coordinate points is uniform, and a smooth touch screen trajectory can be drawn based on the multiple uploaded processed coordinate points.

[0093] The coordinate upload module 33 is used to upload at least two corresponding processed coordinate points as replacement coordinate points for the nth original coordinate point.

[0096] Calculate the sine of the angle between the first line connecting the first coordinate point and the second coordinate point and the second line connecting the second coordinate point and the third coordinate point;
