Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In order to solve the above technical problem, an embodiment of the present disclosure provides a model calibration method, which may be used in a model calibration program, system or device, and an execution subject corresponding to the method may be a terminal or a server of a mobile phone, a tablet, a computer or the like having a touch panel. As shown in fig. 1, the method includes steps S101 to S102:
in step S101, a first sensing signal when a calibration touch operation is performed on the touch panel at a designated calibration position is acquired;
the designated calibration position may include a plurality. The touch object for touch operation can be a finger, a pen, an egg, a flashlight or other electric conductors.
The touch panel in the present application may be a touch panel with a display function, such as a touch display screen; or a touch panel without a display function.
Specifically, the touch panel in the present application may be a capacitive touch panel based on capacitive sensing touch operation; accordingly, the sensing signal may be a capacitive signal.
In addition, in order to make the calibrated target touch operation recognition model more accurate, the user may be prompted to perform the calibration touch operation according to the usual operation habit of the user, for example: when the calibration touch operation is an operation of gradually lifting from a certain designated position on the touch screen, prompting a user to gradually lift according to the usual lifting operation or execute an opposite operation, namely a lifting operation according to the usual pressing operation;
if the usual pressing operation of the user a is vertical pressing relative to the touch panel, the user may be prompted to vertically lift from a specified position on the touch panel or vertically press from above (e.g., directly above) the specified position when performing the calibration touch operation;
for another example: if the pressing operation that the user A is accustomed to at ordinary times is pressing along the inclined direction with the included angle alpha (alpha is not equal to 90 degrees) of the touch panel, when the calibration touch operation is executed, the user can be prompted to roughly press along the angle alpha from the upside (such as the right upside) of a certain specified position on the touch panel in an inclined mode, therefore, the calibrated target touch operation identification model is more accordant with the own operation habit of the user, and the identification effect is natural and more accurate.
In step S102, the preset touch operation recognition model is calibrated according to the designated calibration position and the first sensing signal, so as to obtain a target touch operation recognition model.
By acquiring a first sensing signal when a calibration touch operation is performed on the touch panel at a specified calibration position, the preset touch operation recognition model can be automatically calibrated according to the designated calibration position and the first sensing signal to obtain a target touch operation recognition model, therefore, each user can calibrate the preset touch operation identification model by himself, and because the habit of each user for executing calibration touch operation is different, therefore, the target touch operation identification model obtained after calibration can be adapted to each user respectively, so that the preset touch operation identification model can be calibrated automatically, the target touch operation identification model obtained after calibration can also be different from person to person, the personalized requirements of the user are met, the touch habit of the user is met, and the naturally identified touch operation is more accurate when the touch operation of the user on the touch panel is identified subsequently.
The preset touch operation identification model can be established according to the position of each touch operation relative to the touch panel, the detected induction signal of the induction capacitor and each touch operation when the touch panel is subjected to touch operation for multiple times.
In one embodiment, the step S101 of acquiring a first sensing signal when a calibration touch operation is performed on the touch panel at a specified calibration position includes:
acquiring first induction signals when the same calibration touch operation is executed at a plurality of different designated calibration positions; the designated calibration position comprises any preset position in a touch sensing area and a suspension sensing area of the touch panel.
In this embodiment, the calibration of the preset touch operation recognition model may be completed by performing one or more calibration touch operations. The number of designated calibration positions may be 4, 8, etc.; optionally, each designated calibration position is uniformly dispersed in the touch sensing area and the floating sensing area of the touch panel, or the center, the edge, and other positions of the touch sensing area/the floating sensing area are used as the designated calibration positions.
In practical applications, even for the same user, there may be differences in specific actions when the same touch operation is performed at different positions; in view of this, in the embodiment, by acquiring the first sensing signal when the same calibration touch operation is performed at a plurality of different designated calibration positions, a plurality of sample data of the same calibration touch operation are also acquired, so that the preset touch operation recognition model can be calibrated for a plurality of times, and the influence of accidental factors caused by performing the preset touch operation at only one position is eliminated, so that a more accurate target touch operation recognition model can be obtained, and the touch operations of different user personalities can be accurately recognized.
Further, for the same designated calibration position, the first sensing signals of the same preset touch operation performed at the designated calibration position for multiple times may also be obtained respectively (for example, the first sensing signals when the P1 is performed 4 times after S1 is obtained respectively, that is, the 4 groups of first sensing signals generated when the P1 is performed at S1 are finally obtained), so as to further eliminate the influence of accidental factors caused by performing the preset touch operation once at the designated calibration position, and improve the calibration accuracy of the model again.
In one embodiment, when the calibration touch operation includes an operation of gradually moving from the touch sensing area to the hover sensing area, the designated calibration position includes a first preset starting point within the touch sensing area and/or a first preset ending point within the hover sensing area;
the touch sensing area is a surface area of the touch panel.
The floating sensing area is an area where the touch panel can still sense the user operation when the user performs the spaced touch operation on the touch panel over the touch panel, and the floating reaction area may be an area within 1 cm from the touch panel.
For example: when the designated calibration position is from a predetermined position a in the touch sensing area to an end point B in the hover sensing area, the calibration touch operation is an operation of slowly lifting from the point a to another predetermined position B in the hover sensing area within a certain time (e.g. 0.5s) as an end point, and of course, the operation of slowly lifting varies depending on personal habits, for example: when the user is used to the condition that the finger is lifted vertically upwards, the slow lifting operation is that the finger is lifted vertically upwards from the starting point A, namely the projection coordinate of the finger relative to the touch panel is unchanged (always equal to the preset position) in the lifting process until the point B is reached; when the user is used to lift the finger obliquely upwards or press the finger obliquely downwards, the operation of slowly lifting is started from the point a as the starting point, and the finger is lifted obliquely upwards approximately along the same inclination angle as the normal use, that is, the projection coordinate of the finger relative to the touch panel is gradually changed and is not always equal to the preset position in the lifting process until the point B is reached.
When the calibration touch operation includes an operation of gradually moving from the hover sensing region to the touch sensing region, the designated calibration position includes a second preset starting point in the hover sensing region and/or a second preset ending point in the touch sensing region.
For example: when the designated calibration position is determined to use a point C of a predetermined position in the floating sensing area as a starting point and another point D of a predetermined position in the touch sensing area as an ending point, the calibration touch operation may be an operation of gradually pressing down to the point D of the predetermined position in the touch panel from the point C, and of course, the operation of gradually pressing down to the point D of the touch panel from the point C of the predetermined position as the starting point is different depending on personal habits, which is similar to the above-mentioned operation of gradually lifting up to the point B in the floating sensing area from the point a of the touch sensing area as the starting point, and thus, the description thereof is omitted.
In one embodiment, the model calibration method further includes:
sending out calibration prompt information before the first induction signal is acquired in the step S101; the calibration prompt information is used for instructing a user to execute calibration touch operation on the touch panel at a specified calibration position;
before the first sensing signal is acquired, calibration prompt information can be sent out to prompt a user to start executing the calibration touch operation on the touch panel at a specified calibration position so as to correctly acquire the required first sensing signal and finish automatically calibrating the preset touch operation identification model.
Of course, when the calibration prompt message is sent, in order to make the user more clearly specify the specific calibration position, the specified calibration position may be highlighted and/or voice-prompted, and the highlighting may be to change the color of the specified calibration position, display prompt text at the specified calibration position, or enlarge the display size of the specified calibration position.
In addition, in any way, the specified calibration position can be prompted by a preset starting point and a preset termination.
Optionally, after the first sensing signal is acquired, if a preset position condition is met, the calibration prompt information is re-sent to prompt the user to re-execute the calibration touch operation, where the preset position condition includes:
the position difference between the projection position of the first preset end point on the touch panel and the first preset starting point is greater than a preset position threshold value; or
The position difference between the projection position of the second preset end point on the touch panel and the second preset starting point is greater than a preset position threshold.
When the preset position condition is met, the calibration prompt information is sent to prompt the user to execute the calibration touch operation again, so that the starting point and the ending point of the user in the process of performing the calibration touch operation are ensured to be not greatly different on the touch panel, and the influence on the accuracy of the calibrated target touch operation identification model due to the overlarge difference of the starting point and the ending point of the operation in the process of performing the calibration touch operation is avoided.
As shown in fig. 2, in an embodiment, the step S102 shown in fig. 1, namely calibrating the preset touch operation recognition model according to the designated calibration position and the first sensing signal to obtain the target touch operation recognition model, may include step a 1:
in step a1, the preset classifier of the preset touch operation recognition model is retrained according to the designated calibration position and the first sensing signal to obtain a target classifier of the target touch operation recognition model.
When the target touch operation recognition model is obtained, the preset touch operation recognition model is established according to the position of each touch operation relative to the touch screen and the detected induction signal of the induction capacitor when the touch panel is subjected to touch operation for multiple times, so that the classifier of the preset touch operation recognition model can be trained again according to the specified calibration position and the first induction signal, and the target classifier which better accords with the touch habit of a user is obtained.
The preset classifier may be one or more classifiers, and the preset classifier may be a support vector machine, a neural network, or the like.
In one embodiment, the model calibration method further includes:
after the target touch operation identification model is obtained, a second induction signal when the target touch operation is executed on the touch panel is obtained;
and identifying the target touch operation according to the second induction signal and the target touch operation identification model.
After the target touch operation identification model is obtained, the target touch operation can be automatically identified according to the obtained second sensing signal and the calibrated target touch operation identification model, that is, the calibrated target touch operation identification model is used for identifying which operation the target touch operation is performed on the whole, and compared with the method that the target touch operation is identified by using the preset touch operation identification model before calibration, the identification accuracy can be improved, and the method is suitable for operation habits of different users.
Finally, it is to be noted that: those skilled in the art can freely combine the embodiments of the present disclosure according to actual requirements, and details are not described herein.
