Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It is to be understood that the terms "first" and "second" in the present application are used only for distinguishing different objects, and are not particularly limited. For example, the "first preset touch sensing amount" and the "second preset touch sensing amount" are used to distinguish different preset touch sensing amounts. The "first preset touch sensing amount" may also be written as "second preset touch sensing amount", and the "second preset touch sensing amount" may also be written as "first preset touch sensing amount".
In an embodiment, as shown in fig. 1, a touch operation identification method is provided, and this embodiment is illustrated by applying the method to a terminal, and it may be understood that the method may also be applied to a server, and may also be applied to a system including the terminal and the server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:
The touch operation comprises a pressing operation and a non-pressing operation, and the pressing operation can be a finger pressing operation (for example, a large finger pressing operation); the non-pressing operation comprises a scribing operation and a non-scribing operation, and the non-scribing operation comprises a single-finger touch operation, a two-finger touch operation or a multi-finger touch operation. Further, different types of touch operations are used to implement different functions for different terminals. For example, the terminal is an electronic device, and in an image viewing scene, the two-finger touch operation can zoom and view an image; in a game scene, the line drawing operation can segment the game object. The position information includes position coordinates (x-axis coordinates and y-axis coordinates) of each sensing point.
The sensing points of the touch screen of the terminal have a sensing quantity reference value, and each sensing point has the maximum touch sensing quantity. The touch sensing amount of each sensing point in this example may refer to a difference value between an actual touch sensing amount of each sensing point and a sensing amount reference value. The touch sensing amount of each sensing point has a sensing amount duration. The acquisition frequency of the terminal is predetermined, and a plurality of frames of sensing signals can be acquired within the duration of the touch sensing quantity of each sensing point.
Specifically, the terminal responds to touch operation on the touch screen, scans touch induction quantity of each induction point on the touch screen, determines an acquisition area according to the touch induction quantity of each induction point on the touch screen, and acquires the touch induction quantity and position information of each induction point, matched with each induction signal in at least one frame of induction signals in the acquisition area. The acquisition area may be determined according to that the touch sensing amount of the sensing point in a certain area is greater than that of the sensing points around the certain area. The position information is relative position information between the sensing points.
And 104, determining at least two touch points to be confirmed from the induction points according to the first preset touch induction quantity and each touch induction quantity.
The first preset touch induction amount is a first coefficient multiple of the maximum touch induction amount of the induction point, the first coefficient is a percentage, and the first coefficient can be 30% or 40% and the like. The number of the touch points to be confirmed may be two or more, and the example is described with two touch points to be confirmed.
Specifically, in response to a touch operation on the touch screen, acquiring touch induction quantity and position information of each induction point of a current frame induction signal, and determining induction points with touch induction quantity larger than a first preset touch induction quantity from the induction points according to the first preset touch induction quantity and each touch induction quantity to obtain two touch points to be confirmed. When two touch points to be confirmed or a plurality of touch points to be confirmed exist, the touch points to be confirmed need to be confirmed, whether the touch points to be confirmed can be combined or need to be split is judged, and the touch type of touch operation is further determined. If the touch point to be confirmed is one, the touch point to be confirmed is a touch point, the corresponding touch operation is a quick line drawing operation, and the touch operation does not need to be identified.
And step 106, if the sensing points on the traveling route of at least two touch points to be confirmed are smaller than a second preset touch sensing quantity, determining that the touch operation is a non-pressing operation.
The second preset touch induction amount is greater than the first preset touch induction amount, the second preset touch induction amount is a second coefficient multiple of the maximum touch induction amount of the induction point, the second coefficient is a percentage, and the second coefficient may be, but is not limited to, 50%. The travel route is determined according to the two touch points to be confirmed, namely, the travel route from one touch point to be confirmed to the other touch point to be confirmed is determined according to the relative direction between the two touch points to be confirmed and the relative direction between the two touch points to be confirmed. The following method for determining the travel route of the touch point to be confirmed is shown in fig. 2, and includes the following steps:
in step 202, a relative direction between any two touch points to be confirmed in at least two touch points to be confirmed is determined.
The relative direction is determined according to the position information of the two touch points to be confirmed, namely, the azimuth angles before the two touch points with confirmation are calculated according to the position information. Calculating the azimuth angle between two points according to the position coordinates can be determined by the prior art, and is not described herein. For example, as shown in fig. 3, the touch point a to be confirmed and the touch point B to be confirmed may determine an azimuth angle of the touch point B to be confirmed with respect to the touch point a to be confirmed according to the position coordinates of the touch point a to be confirmed and the touch point B to be confirmed.
Further, when determining the relative direction between the touch points to be confirmed, the reference point may be determined according to the touch induction amount of the touch point to be confirmed, the touch point to be confirmed with the largest or smallest touch induction amount may be used as the reference point, and the other touch point to be confirmed corresponds to the direction of the reference point.
Specifically, any two touch points to be confirmed in the at least two touch points to be confirmed are determined, at least one group of two touch points to be confirmed can be obtained, and the relative direction between any two touch points to be confirmed is determined.
In step 204, one to-be-confirmed touch point of any two to-be-confirmed touch points is used as a starting point, and the other to-be-confirmed touch point is used as an end point.
And determining a starting point and an end point on the determined travel route according to the touch induction quantity of the touch point to be confirmed. The touch point to be confirmed with the minimum touch induction quantity can be confirmed as a starting point, and the touch point to be confirmed with the maximum touch induction quantity can be confirmed as an end point. The touch point to be confirmed with the minimum touch induction quantity can be confirmed as an end point, and the touch point to be confirmed with the maximum touch induction quantity can be confirmed as a start point. In this embodiment, the touch point to be confirmed with the smallest touch sensing amount is confirmed as a starting point, and the touch point to be confirmed with the largest touch sensing amount is confirmed as an end point.
And step 206, starting from the starting point, taking the starting point as the current traveling point, and taking the sensing point with the largest touch sensing quantity adjacent to the current traveling point in the opposite direction as the next traveling point on the traveling route.
And step 208, updating the next travel point to the current travel point until the end point is reached, and obtaining a travel route between any two touch points to be confirmed.
Specifically, a touch point to be confirmed with the smallest touch induction amount is confirmed as a starting point, a touch point to be confirmed with the largest touch induction amount is confirmed as an end point, starting from the starting point, the starting point is used as a current travel point on a travel route, a touch point with the largest touch induction amount adjacent to the current travel point in the opposite direction is used as a next travel point on the travel route, and the touch point to be confirmed is updated as the current travel point according to the next travel point until the end point is reached, so that a travel route between any two touch points to be confirmed is obtained. And the touch induction quantity of the induction point is greater than a second preset touch induction quantity, or equal to the second preset touch induction quantity, or less than the second preset touch induction quantity.
For example, as shown in fig. 4, a schematic diagram of the touch sensing amount of each sensing point in a frame of sensing signal in one embodiment is shown, the sensing signal includes a plurality of sensing points and two touch points to be confirmed, the touch sensing amount of the touch point 1 to be confirmed is 895, the touch sensing amount of the touch point 2 to be confirmed is 930, the touch point 1 to be confirmed is a starting point, the touch point 2 to be confirmed is an end point, the touch point 2 to be confirmed is in the northeast direction of the touch point 1 to be confirmed, the starting point is taken as a current traveling point on the traveling route, sensing points with touch sensing quantities of 832 and 870 adjacent to the touch point 1 to be confirmed are obtained in the opposite direction, the sensing point with the touch sensing quantity of 870 is taken as the next traveling point, and updating the current travel point according to the next travel point to obtain induction points with induction touch quantities of 816, 789, 838 and 887 until the touch point 2 to be confirmed is reached, and obtaining a travel route.
In the method for determining the travel route, a relative direction between any two touch points to be determined in any two touch points to be determined is determined, one touch point to be determined in any two touch points to be determined is used as a starting point, the other touch point to be determined is used as an end point, the starting point is used as a current travel point, a sensing point with the largest touch sensing quantity adjacent to the current travel point in the opposite direction is used as a next travel point on the travel route, and the next travel point is updated to be the current travel point until the end point is reached, so that the travel route between any two touch points to be determined is obtained. The sensing touch quantity of the sensing points in the opposite direction is screened, the next conducting point is determined, and the accuracy of the advancing route is improved by combining the direction characteristic of touch operation.
Specifically, by determining the relative direction between any two touch points to be confirmed in two touch points to be confirmed, taking one touch point to be confirmed in any two touch points to be confirmed as a starting point, taking the other touch point to be confirmed as an end point, starting from the starting point, taking the starting point as a current travel point, taking an induction point with the largest touch induction quantity adjacent to the current travel point in the opposite direction as a next travel point on a travel route, updating the next travel point as the current travel point until the end point is reached, obtaining the travel route between any two touch points to be confirmed, if the induction point on the travel route is smaller than a second preset touch induction quantity, indicating that the two touch points to be confirmed are two discontinuous points, requiring point removal, and determining the touch operation as a non-pressing operation.
For example, in fig. 4, the touch sensing amount of the touch point 1 to be confirmed is 895, the touch sensing amount of the touch point 2 to be confirmed is 930, the touch point 1 to be confirmed is a starting point, the touch point 2 to be confirmed is an end point, the touch point 2 to be confirmed is in the northeast direction of the touch point 1 to be confirmed, the starting point is taken as a current travel point on the travel route, the sensing points with touch sensing amounts 832 and 870 adjacent to the touch point 1 to be confirmed are obtained in the opposite direction, the sensing point with touch sensing amount 870 is taken as a next travel point, the sensing point with touch sensing amount 870 is updated as the current travel point according to the next travel point, the sensing points with sensing touch amounts 816, 789, 838, and 887 are obtained, and the travel route is obtained until the touch point 2 to be confirmed is reached. And no induction point smaller than a second preset touch induction quantity exists on the travel route, the touch point 2 to be confirmed with the touch induction quantity of 930 is determined as a touch point, and the touch operation is determined as a large finger or large palm pressing touch operation.
As shown in fig. 5, which is a schematic diagram of the touch sensing amount of each sensing point in a frame of sensing signal in an embodiment, the sensing signal includes a plurality of sensing points and two touch points to be confirmed, the touch sensing amount of the touch point 1 to be confirmed is 1129, the touch sensing amount of the touch point 2 to be confirmed is 1289, the touch point 1 to be confirmed is a starting point, the touch point 2 to be confirmed is an end point, the touch point 2 to be confirmed is in the northeast direction of the touch point 1 to be confirmed, the starting point is taken as a current traveling point on the traveling route, sensing points adjacent to the touch point 1 to be confirmed and having touch sensing amounts 941 and 871 are obtained in opposite directions, the sensing point having touch sensing amount 941 is taken as a next traveling point, the current traveling point is updated according to the next traveling point, so as to obtain a sensing point having a sensing touch amount 214, and the sensing point having touch amount 214 is smaller than a second preset touch sensing amount, that is, there is an induction point smaller than the second preset touch induction amount on the traveling route, the induction point cannot reach the touch point 2 to be confirmed, the touch point 1 to be confirmed and the touch point 2 to be confirmed need to be split, two different touch points are obtained, and it is determined that the touch operation is a two-finger operation.
In the identification method of the touch operation, the touch induction quantity and the position information of each induction point of at least one frame of induction signal are collected by responding to the touch operation of the touch screen; determining at least two touch points to be confirmed from each induction point according to the first preset touch induction quantity and each touch induction quantity; and if the sensing points on the traveling routes of the at least two touch points to be confirmed are smaller than a second preset touch sensing quantity, determining that the touch operation is a non-pressing operation. The method comprises the steps that according to at least two touch points to be confirmed, which are matched with at least one frame of induction signal, an induction point on a travel route is detected to be smaller than a second preset touch induction quantity, which indicates that an induction point with a small induction quantity exists between the at least two touch points to be confirmed, and the two touch points to be confirmed are discontinuous in split and are two independent touch points. According to the method, the touch control mode of the touch control operation is identified according to the touch control consistency between the two touch control points to be confirmed, and the accuracy of touch control operation identification is improved.
In another embodiment, as shown in fig. 6, a touch operation identification method is provided, and this embodiment is illustrated by applying the method to a terminal, and it is understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:
Specifically, the terminal responds to touch operation on the touch screen and acquires touch induction quantity and position information of each induction point of at least one frame of induction signal, namely continuously acquires the touch induction quantity and position information of each induction point matched with each induction signal of multiple frames of induction signals. In the process of touch operation identification, a frame of induction signal is taken as a unit for processing. For example, the terminal responds to the touch operation of the touch screen and collects the touch induction quantity and the position information of each induction point matched with each induction signal of 5 frames. In this embodiment, a multi-frame sensing signal collected continuously is taken as an example for description.
In this embodiment, two touch points to be confirmed are taken as an example for description, and when there are more than three touch points to be confirmed, at least one group of two touch points to be confirmed is obtained by taking any two touch points to be confirmed as a group. The corresponding touch operation recognition methods are the same.
In step 606, it is determined whether there are sensing points on the traveling routes of the at least two touch points to be confirmed that are smaller than the second preset touch sensing amount, if yes, step 608 is executed, otherwise, step 618 is executed.
Specifically, a relative direction between any two touch points to be confirmed in a current frame (the current frame may be a first frame in consecutive multiple frames) is determined, one touch point to be confirmed in any two touch points to be confirmed is taken as a starting point, the other touch point to be confirmed is taken as an end point, the starting point is taken as a current travel point, a sensing point with the largest touch induction quantity adjacent to the current travel point in the opposite direction is taken as a next travel point on a travel route, the next travel point is updated as the current travel point until the end point is reached, the travel route between any two touch points to be confirmed is obtained, and whether an induction point on the travel route of at least two touch points to be confirmed is smaller than a second preset touch induction quantity is judged.
In step 608, if there is a sensing point smaller than the second preset touch sensing amount on the traveling route of at least two touch points to be confirmed of the current frame sensing signal in the at least one frame of sensing signal, it is determined that the at least two touch points to be confirmed do not need to be merged.
Specifically, according to the fact that the number of sensing points on the traveling route of two touch points to be confirmed of a current frame sensing signal in at least one frame of sensing signals is smaller than a second preset touch sensing amount, an identification result that the two touch points to be confirmed do not need to be combined is obtained, the identification result is counted, and the identification result of continuous multi-frame sensing signals is obtained for inspection. It can be understood that, under normal conditions, the results that touch points to be confirmed in consecutive multi-frame sensing signals need to be merged or split are the same, and in order to improve the identification accuracy of touch operations, on the basis of obtaining the identification result of the current frame sensing signal, it is detected whether the identification results of the touch points to be confirmed in consecutive multi-frame sensing signals are the same. And determining that the two touch points to be confirmed do not need to be combined, namely determining that the touch operation may be two-finger touch operation, and continuously acquiring the touch induction quantity of each induction point of the multi-frame induction signals for identification in order to ensure the accuracy of touch operation identification. Further, the duration of the touch sensing amount of different touch operations is different, that is, the number of the collected continuous sensing signals is different. For example, the touch sensing amount of the quick-scribing sensing signal lasts up to 3 frames.
The non-scribing operation includes a two-finger touch operation, a multi-finger touch operation and the like.
Specifically, if it is determined that at least two to-be-confirmed touch points matched with each other in the continuous multi-frame sensing signals do not need to be combined, it is determined that the touch operation is a non-scribing operation. Further, if two touch points to be confirmed, which are respectively matched with the continuous multi-frame sensing signals, do not need to be combined, determining that the touch operation is a double-finger touch operation; and if the three touch points to be confirmed, which are respectively matched with the continuous multi-frame sensing signals, do not need to be combined, determining that the touch operation is the three-finger touch operation.
In step 614, if it is determined that at least two to-be-confirmed touch points of at least one frame of sensing signal need to be merged in at least two to-be-confirmed touch points matched with each other in the continuous multi-frame sensing signals, it is determined that the touch operation is a scribing operation.
Specifically, if there are sensing points smaller than a second preset touch sensing amount on the traveling route of two to-be-confirmed touch points of the current frame sensing signal, it is determined that at least two to-be-confirmed touch points do not need to be merged, and if there is a frame of sensing signal in the continuous multi-frame sensing signal that two to-be-confirmed touch points of the frame sensing signal need to be merged or at least two to-be-confirmed touch points of the multi-frame sensing signal need to be merged, it is determined that the touch operation is a scribing operation.
Optionally, in an embodiment, if there is a sensing point smaller than the second preset touch sensing amount on the traveling route of at least two to-be-confirmed touch points of the current frame sensing signal, it is determined that the at least two to-be-confirmed touch points do not need to be merged, and if only one touch point exists in the second frame sensing signal or the multiple frames of sensing signals, it is determined that the touch operation is a line drawing operation. For example, the touch operation is a quick line drawing operation, the touch sensing amount of each sensing point of the first frame of sensing signal is collected as shown in fig. 7a, and the touch sensing amount of each sensing point of the second frame of sensing signal is collected as shown in fig. 7 b. Determining at least two touch points to be confirmed (touch induction quantity is 911 and 812) from each induction point according to the first frame of induction signal shown in fig. 7a and according to a first preset touch induction quantity and the touch induction quantity of each induction point of the first frame of induction signal; according to the fact that the induction points (the touch induction quantity is 34) on the traveling route of the at least two touch points to be confirmed are smaller than a second preset touch induction quantity, it is determined that the touch points to be confirmed with the touch induction quantities of 911 and 812 are discontinuous, and the touch points to be confirmed need to be split. According to the second frame of sensing signals shown in fig. 7b, a touch point to be confirmed is determined from the sensing points according to the first preset touch sensing amount and the touch sensing amount of each sensing point of the first frame of sensing signals (the touch sensing amount is 1026). The two frames of sensing signals have different results, and continuous multi-frame sensing signals need to be identified.
In step 616, if no sensing point exists on the traveling route of at least two touch points to be confirmed, which is smaller than the second preset touch sensing amount, it is determined that the touch operation is a pressing operation.
It can be understood that there is only one touch point in the scribing operation. The touch induction quantity of the pressing operation (such as pressing by a large finger or a large palm) is uniform in the whole induction quantity, and the difference value of the touch induction quantity among all induction points is uniform.
In the identification method of the touch operation, the touch induction quantity and the position information of each induction point of continuous multi-frame induction signals are acquired by responding to the touch operation on the touch screen; determining at least two touch points to be confirmed from each sensing point according to the first preset touch sensing quantity and each touch sensing quantity; and if the induction points on the travelling routes of the at least two touch points to be confirmed are smaller than the second preset touch induction quantity, determining that the touch operation is a non-pressing operation, if the induction points on the travelling routes of the at least two touch points to be confirmed are not smaller than the second preset touch induction quantity, determining that the touch operation is a pressing operation, and confirming the touch operation according to the continuous multi-frame induction signals. The method comprises the steps that according to at least two touch points to be confirmed, which are matched with at least one frame of induction signal, an induction point on a travel route is detected to be smaller than a second preset touch induction quantity, which indicates that an induction point with a small induction quantity exists between the at least two touch points to be confirmed, and the two touch points to be confirmed are discontinuous in split and are two independent touch points. According to the method, the touch control mode of the touch control operation is identified according to the touch control consistency between two touch control points to be confirmed, the touch control operation is confirmed according to continuous multi-frame induction signals, and the accuracy of touch control operation identification is improved.
