Fig. 1 shows a schematic flow chart of a method for preventing an ink screen from being touched by mistake, which includes: S100-S300, wherein S100 is used for determining user behavior characteristics in the current scene based on collected user operations of the user on the ink screen in the current scene, quantifying the user behavior characteristics and determining a plurality of characteristic factors; s200, acquiring a plurality of preset response events and historical response events, and predicting the occurrence probability of each preset response event according to the plurality of characteristic factors and the historical response events; and S300, taking a preset response event corresponding to the maximum occurrence probability as a target response event, and using the target response event to respond to the user operation. Therefore, more characteristic factors are introduced to judge possible operations, most application scenes are covered, misjudgment and misoperations are reduced, the method adapts to the personalized operation habits of users, and the operation experience of the users is improved.
Specifically, in S100, a user behavior feature in a current scene is determined based on collected user operations of the user on the ink screen in the current scene, and the user behavior feature is quantized to determine a plurality of feature factors. Here, a user touches the ink screen, at this time, the operation of the user in the current scene is collected through the ink screen, the behavior characteristics of the user in the current scene, such as the finger click position, the finger click duration, and other characteristics of the user, are determined, for the behavior characteristics, the behavior characteristics may be quantified using characteristic factors, for example, a preset coordinate system is established on the ink screen, the coordinate position touched by the user and a vector corresponding to the touch displacement are determined through the preset coordinate system, and the behavior characteristics of the user are collected through collection and arrangement of the operation of the user, such as the coordinate position of the pressed region of the touch screen, the pressing area (for example, calculated through TPsensor), the pressing time, the holding angle (calculated through G sensor), and the moving path of the pressed region, and several indexes. And the actual reaction of the user operation is confirmed or overturned, so that the behavior of the user can be learned by combining the human engineering principle.
In step S200, a plurality of preset response events and historical response events are obtained, and the occurrence probability of each preset response event is predicted according to the plurality of characteristic factors and the historical response events. Here, all events that have responded to the user are stored as historical responded events, the occurrence probability of each preset response event is calculated according to a plurality of characteristic factors, such as user touch time, touch position, and the like, for example, if the touch screen contact area is greater than a preset area threshold, the probability that the click is an invalid click is obtained as 1, and meanwhile, the occurrence probability of each preset response event is determined in combination with the historical responded events, for example, if a user withdrawal operation occurs after a user identical operation is responded by an a event, the probability that the user operation responds with the a event is reduced.
In S300, a preset response event corresponding to the maximum occurrence probability is used as a target response event, and the target response event is used to respond to the user operation. Here, the preset response event with the maximum occurrence probability is an operation purpose obtained by prejudging the current operation of the user, and the target response event is used for responding the operation of the user to complete the operation purpose corresponding to the operation of the user, for example, the user clicks the previous page, at this time, according to the obtained characteristic factor corresponding to the click action of the user, the preset response event with the maximum occurrence probability obtained through calculation and prediction is page turning to the previous page, and then the page turning to the previous page is used for responding to the operation of the user.
In an optional embodiment of the present application, the method includes S400 and S500, where in S400, a secondary operation of the user within a preset time period after the target response event occurs is obtained, and an occurrence probability of each preset response event is updated according to the secondary operation; in S500, the target response event and the secondary operation record are stored as historical responded events. Here, secondary operations within a preset time period are acquired, and the occurrence probability of each preset response event is reduced or increased according to the secondary operations. For example, when the user corrects the response event corresponding to the current operation through the secondary operation, the occurrence probability of the response event calculated under the same characteristic factor can be reduced by increasing the coefficient; when the user confirms the response event corresponding to the current operation through the secondary operation, the occurrence probability calculated under the same characteristic factor of the response event can be increased in a weighting mode.
In an optional embodiment of the present application, in S400, it is determined whether the secondary operation is a negative operation, so as to obtain a determination result; and updating the occurrence probability of each preset response event according to the judgment result. Here, in a practical application environment of the ink screen, the negation operation is an operation that is given a definite definition in advance based on the function, for example, "next page" and "previous page" are mutually negation operations, "enter" and "return" are mutually negation operations.
In an optional embodiment of the application, in the reading interface, a certain displacement occurs in a path of a coordinate center in several factors acquired in real time, so that it can be determined that the user has performed a "sliding operation", and the user is helped to turn to the "next page" in response. This has only two consequences: in the first result, the response event of the user for turning to the next page meets the operation expectation of the user, the user will continue to read and perform subsequent operations, and then the last judgment is "probability calculation success", the probability calculation of the correlation factor will be confirmed, and the training will be continuously strengthened. In the second result, this judgment is not the actual requirement of the user, so the user does not recognize the response operation of the system, and the user will naturally make a correction, that is, correct the previous error response through the subsequent operation. For example, if the coordinate center displacement is only slightly jittered when the user holds the hand, and the user does not intend to turn a page, the response event of the page turning is an "erroneous judgment" and an "erroneous operation" which are not expected by the user, and the user can restore to the state before the operation within a preset time period, for example, turn back to the previous page, which is a negative operation, that is, a reverse operation is performed for the judgment, and for the occurrence of such an operation, the correlation coefficient is reduced to reduce the probability of responding to the page turning event under the same operation, which may affect the subsequent interpretation of the response event under similar characteristic factors.
In an optional embodiment of the present application, in S100, collecting user operations to determine coordinates of a contact point of a user on an ink screen in a current scene; and determining the user behavior characteristics under the current scene based on the contact point coordinates. Here, touch point coordinates corresponding to a touch operation of a user on the ink screen are acquired, and a plurality of parameters corresponding to the user behavior characteristics can be determined based on the touch point coordinates. In an optional embodiment of the present application, the user behavior characteristics include a touch area, a touch center point, a duration of the touch, a holding angle, a touch point moving distance, and a touch point moving direction. Fig. 2 is a schematic diagram of a user holding an ink screen in an actual application scenario, where the left side shows a common posture of the user's palm naturally holding the ink screen, and the posture is also the most comfortable state for the user to hold, but this state may be ignored by software when touching the ink screen, and a simple process is a click, and the right side is a contact area that can be determined under the coordinates of the contact point, and a corresponding geometric parameter, such as the geometric center of the contact surface, can be obtained. If we analyze and summarize its characteristics, at least the following characteristics can be obtained: contact area far exceeds the area of a fingertip, contact is maintained for a long time, the geometric center is close to the edge of the screen, the screen is held in a sitting or supine position, and there is no significant path movement.
Following the above embodiment, the following behavior feature factors can be obtained after quantifying the behavior features: the method comprises the steps of touch screen contact area, continuous reporting time, distance from a touch center point to an edge, holding angle, touch point moving distance and moving direction. The operation is typical and relatively easy to judge, and the real operation of the user can be reflected in the change of the five parameters. The quantized feature factor may be a plurality of thresholds, for example, a small contact area, a short distance shift or click.
In an optional embodiment of the present application, the preset response event includes a call-out menu, a page up, a page down, and no response. Here, there are 4 kinds of response events coexisting under the book reading interface, which are: b is1Call-out menu, B2Turn over the previous page, B3Turn over the next page, B4Do nothing. Where doing nothing, i.e. not responding, is also an option, which may beWhen a user touches the screen while holding the touch screen, the system receives an interrupt signal sent by the TP, but the system judges that the touch screen is not the active behavior of the user through the operation of the touch characteristic, and the system does nothing at this time. Fig. 3 is a schematic diagram illustrating an actual application scenario of an ink screen in an alternative embodiment of the present application, where the preset response event includes an outgoing call menu, a page up, a page down, and no response.
In an optional embodiment of the present application, in S200, a probability value corresponding to each preset response event is calculated according to a single characteristic factor; calculating a probability value corresponding to each preset response event according to the historical responded events; and accumulating the probability values corresponding to all the single characteristic factors corresponding to the single preset response event and the probability values corresponding to the historical responded events to determine the occurrence probability of each preset response event. The occurrence probability value of a single preset response event is calculated under the single characteristic factor, then the occurrence probability value corresponding to each preset response event is calculated by using historical responded events, and then all the probability values of the single preset response event obtained by calculation are accumulated to obtain the occurrence probability value.
In an optional embodiment of the present application, the occurrence probability is calculated for the following four preset response events: b is1Call-out menu, B2Turn over the previous page, B3Turn over the next page, B4Do nothing. At this time, the calculation is performed according to the following five characteristic factors: H. the method comprises the steps of touch screen contact area, I, continuous reporting time, J, distance from a touch center point to an edge, K, holding angle and L, touch point moving distance and direction. According to the conditional probability formula, setting A as the triggered event and the triggering condition, and B1、B2、B3、B4Indicating a possible response event, P (B)iI A) indicates that B occurs on the premise that A has already occurrediThe size of the probability of (c). Considering the weighted calculation of several factors, P (B)iI A) will be at the original base P0(Bi) The corresponding correction is carried out, and the value B corresponding to the maximum probability value (needing to distinguish between positive and negative values and taking the maximum positive value) is obtainediWill represent the next action that the user wants to trigger,the cumulative formula is as follows:
P(Bi|A)＝P0(Bi)+P(Bi|H)+P(Bi|I)+P(Bi|J)+P(Bi|K)+P(Bi|L)
the above five factors are the most common, one or more of the factors can be adopted in practical use, and new factors can also be added, and the more effective factors are introduced, which is in principle helpful for judging the real needs of users. It should be noted that other characteristic factors are within the scope of the present application.
In an optional embodiment of the present application, in S200, a parameter threshold corresponding to each feature factor is called, and a probability value corresponding to each preset response event under the single feature factor is determined based on the parameter threshold. Here, a parameter threshold may be set for each characteristic factor, for example, the touch screen contact area H, where the threshold area is H, and if H > H, P (B) may be understood as P (H)4H) is approximately equal to 1; continuously reporting time I, setting the threshold area as I, and if I > I, then it can be understood as P (B)4I) is approximately equal to 1; the touch center-to-edge distance J may be defined as P (B) if J is 04I J) is approximately equal to 1; the grip angle K can be understood as P (B) when K is held in the supine position4I K) is approximately equal to 1; the touch point movement distance and direction L may be regarded as P (B) if L is 04L) ≈ 1, if L < 0, then P (B) can be understood3L) ≈ 1, if L > 0, then P (B) may be understood2|L)≈1。
Fig. 4 is a schematic flow chart of a method for preventing a false touch of an ink screen in an optional embodiment of the present application, in which operation characteristics of a user are ergonomically determined, a plurality of characteristic factors are quantitatively determined for the operation characteristics of the user, and each characteristic factor is used to perform probability calculation on each preset response event to obtain a probability result. At the moment, the operation of the user in the current scene is collected through the ink screen, the characteristics of the finger click position, the finger click duration time and the like of the user in the current scene are determined, then a preset coordinate system is established on the ink screen, the coordinate position touched by the user and the vector corresponding to the touch displacement are determined through the preset coordinate system, and the user can be pressed through the touch screenThe coordinate position of the pressing area, the pressing area (e.g., as calculated by the TPsensor), the time of the pressing, the grip angle (as calculated by the G sensor), and the moving path of the pressing area. Under the book reading interface of the electronic ink screen, 4 response events coexist, which are respectively: b is1Call-out menu, B2Turn over the previous page, B3Turn over the next page, B4Do nothing. The probability of occurrence of the four response events is calculated according to the following five characteristic factors: H. the method comprises the steps of touch screen contact area, I, continuous reporting time, J, distance from a touch center point to an edge, K, holding angle and L, touch point moving distance and direction. And accumulating the probability values calculated by the five characteristic factors corresponding to each response event to obtain the predicted occurrence probability of the response event. Then, setting a parameter threshold value for each characteristic factor to perform weighted calculation on the occurrence probability value of each response event: the touch screen contact area H is set as H, if H > H, P (B) can be understood as4H) is approximately equal to 1; continuously reporting time I, setting the threshold area as I, and if I > I, then it can be understood as P (B)4I) is approximately equal to 1; the touch center-to-edge distance J may be defined as P (B) if J is 04I J) is approximately equal to 1; the grip angle K can be understood as P (B) when K is held in the supine position4I K) is approximately equal to 1; the touch point movement distance and direction L may be regarded as P (B) if L is 04L) ≈ 1, if L < 0, then P (B) can be understood3L) ≈ 1, if L > 0, then P (B) may be understood2L) ≈ 1. The occurrence probabilities of the four response events can be obtained through the calculation.
In the embodiment, a preset response event with the highest probability value among the four response events is selected as a target response event to respond to user operation, that is, system operation is generated according to the target response event, then secondary operation of the user is obtained, whether the secondary operation of the user is confirmation operation is judged, if not, the user performs reverse operation, that is, negative operation, the probability of the target response event under the same user operation characteristic is reduced, the calculation probability of the target response event can be reduced by using a weighted calculation mode, and all the response events are stored as historical responded events. It should be noted that, in the actual application environment of the ink screen, the negation operation is an operation that is clearly defined in advance based on a function, for example, "next page" and "previous page" mutually negate, and "enter" and "return" mutually negate. Therefore, more characteristic factors are introduced to judge possible operations, most application scenes are covered, misjudgment and misoperations are reduced, the method adapts to the personalized operation habits of users, and the operation experience of the users is improved.
