[0039] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0040] Example 1

[0041] In order to correct the user's accidental touch or wrong press, an embodiment of the present invention provides a key error correction method, which can be used for but not limited to color film keys, touch screen keys, etc. The error correction method divides each key in the key area into at least two sub-areas in advance, wherein the key area includes at least two keys. Figure 1 A schematic diagram of the division of a part of the key area provided by an exemplary embodiment of the present invention. The key area must include at least two keys, and each key is evenly divided into n sub-areas ( Figure 1 The area of ​​each sub-region is S i ,in, S represents the area of ​​each key. In a specific implementation, the division operation can be completed by mapping the keys to a discrete grid and then dividing the grid into n sub-areas.

[0042] It should be noted that the number of sub-areas divided by each button can be set according to actual needs; the number of sub-areas divided by each button can be the same or different; the area of ​​each sub-area can be the same or different.

[0043] Figure 2 A flow chart of a method for correcting an error of a key touch provided by an exemplary embodiment of the present invention, the method comprising the following steps:

[0044] Step 201: In response to a touch instruction on a key area, determine a spatial weight value and a temporal weight value of a sub-area.

[0045] The key area includes at least two keys, each key is divided into at least two sub-areas, the spatial weight value is determined according to the position of the sub-area and the touch position of the touch instruction, and the temporal weight value is determined according to the historical touch data of the key. The spatial weight value represents the importance and influence of the data point in the spatial dimension. The temporal weight value represents the importance or influence of the data point in the dimension.

[0046] In one embodiment, when a key is touched, the horizontal and vertical coordinates of the touch position on the key area and the center coordinates of the touch position in the sub-area are recorded. The spatial weight value of the sub-area is calculated using a Gaussian function based on the horizontal and vertical coordinates of the touch position on the key area and the center coordinates of the touch position in the sub-area. The closer the center coordinates of the touch position in the sub-area are to the horizontal and vertical coordinates of the touch position on the key area, the greater the weight value of the center coordinates of the touch position in the sub-area. The spatial weight value refers to the contribution of data points at different positions to the final weighted result in the spatial dimension. Generally, data points whose center coordinates of the sub-area are closer to the horizontal and vertical coordinates of the touch position will have a greater impact on the weighted average result, while data points whose distance is farther will have less impact on the weighted average result. Therefore, when calculating the spatial weight value, a distance-based method, such as a Gaussian function, is usually used to describe the contribution of data points at different distances to the weighted average result, thereby obtaining a spatial weight value.

[0047] In one embodiment, the calculation formula of the spatial weight value of the sub-region is as follows:

[0048]

[0049] Among them, W i represents the spatial weight value of the ith sub-region; (x i ,y i ) represents the center coordinate of the i-th sub-region; σ i represents the variance of the Gaussian function; (x, y) represents the horizontal and vertical coordinates; n represents the total number of sub-areas into which each key is divided.

[0050] In one embodiment, when a key is touched, historical touch data needs to be recorded. The historical touch data includes the timestamp of the historical touch event, the time weight value of the historical touch event, and the touch position of the historical touch event. The final weight of the historical touch event can be determined by the touch position of the historical touch event.

[0051] The time weight value is calculated using an exponential decay function based on the timestamps of historical touch events and the weight values ​​of historical touch events. The time weight value refers to the contribution of sub-areas at different times to the weighted result in the time dimension. Generally speaking, sub-areas with a close time interval to the current touch button have a greater impact on the weighted result, while data points that are farther away in the past will gradually reduce their impact on the weighted average result. Therefore, when calculating the time weight, an exponential decay function can be used, but is not limited to, to reflect the importance of recent data points to the weighted average result, and to decay the impact of past data points over time, thereby obtaining a time weight value.

[0052] In one embodiment, the calculation formula of the time weight value is as follows:

[0053]

[0054] Among them, W tm represents the time weight value of the historical touch event; α represents the decay rate parameter, which controls the degree of weight decay over time; t k Indicates the timestamp of the kth touch event; W k represents the weight value of the kth touch event; m represents the number of historical touch events.

[0055] By dividing each key into multiple sub-areas in equal parts, and by calculating the spatial weight value and time weight value of each sub-area, the spatial weight value and time weight value are used to jointly determine the final touch key in the spatial dimension and the time dimension, the user's input intention can be accurately determined, thereby improving the accuracy of the user's touch key.

[0056] Step 202: Calculate the final weight of the key according to the spatial weight value and the temporal weight value. In one embodiment, the spatial weight value and the temporal weight value are weighted to obtain the final weight.

[0057] In one embodiment, the calculation formula of the final weight is as follows:

[0058]

[0059] Among them, W i represents the spatial weight value of the i-th sub-region; W tm represents the time weight value of the historical touch event; Wtotal represents the final weight; λ represents the ratio of the spatial weight to the temporal weight, wherein the value of λ is related to the actual application scenario. In the scenario of the embodiment of the present invention, the optimal value of λ is 0.5.

[0060] The judgment in the spatial dimension is only to calculate a touch at the physical level. If the key is pressed at the edge of two keys, it is easy to make mistakes by judging in space alone. At this time, it is necessary to judge the result of historical touches at this point, that is, the time dimension. Therefore, by correcting the key in two dimensions, the user's input intention can be accurately determined, which improves the reliability of the key.

[0061] Step 203: Determine the key targeted by the touch instruction according to the final weight.

[0062] In one embodiment, the final weights of the various keys are compared to determine which key is finally pressed. Usually, the final weights are numerically compared, and the key with the largest final weight is selected as the key actually pressed. In a specific implementation, a threshold may be set. If the final weight is greater than the threshold, a numerical comparison is performed. If the final weight is lower than the threshold, the weight value is directly filtered out.

[0063] Combine the following Figure 3 , further explains the method of correcting accidental key touches.

[0064] Step 301: When a key receives a touch instruction, the touch position and touch time of the touch key are recorded.

[0065] Step 302: Calculate a spatial weight value of the touch position by using a Gaussian function according to the touch position.

[0066] Step 303: Calculate the time weight value of the touch position using an exponential decay function according to the touch position and the historical touch record of the touch position.

[0067] Step 304: Perform weighted calculation on the spatial weight value of the touch position and the temporal weight value of the touch position to obtain a final weight value of the touch position.

[0068] Step 305: Determine the key that is finally pressed according to the final weight of the touch position.
