Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, in the prior art, there is a deviation between the actual touch point position information 6 of the touch key and the theoretical touch point position information 5 of the touch key, which causes a deviation between the actual touch area information 2 of the touch key and the theoretical touch effective area information 1 of the touch key, and therefore, the actual effective touch area information 4 of the prior art touch key is a portion where the theoretical touch effective area information 1 of the touch key and the actual touch area information 2 of the touch key overlap.
In view of the foregoing problems, embodiments of the present invention provide a touch confirmation method and apparatus, which are suitable for various devices with touch screen input, such as a demonstrator, a touch screen mobile phone, and a tablet computer. As shown in fig. 1 to 3, an embodiment of the present invention provides a touch confirmation method, including:
step S200: adjusting theoretical touch effective area information 1 of the touch key according to the average position deviation information of the effective touch points of the touch key, and obtaining actual touch effective area information 3 of the touch key;
step S300: receiving touch point position information of the touch key, and judging whether the touch point position information of the touch key is effective according to the actual touch effective area information 3 of the touch key;
step S400: and if the touch point position information of the touch key is valid, setting the touch of the touch key to be valid.
Based on the touch confirmation method provided by the embodiment of the invention, the theoretical touch effective area information 1 of the touch key is adjusted according to the average position deviation information of the effective touch point of the touch key, and the actual touch effective area information 2 of the touch key is obtained, so that the actual touch area information 2 of the touch key is the same as the actual touch effective area information 3 of the touch key, and the probability that the touch point of the touch key falls in the actual touch effective area of the touch key is increased when judging whether the touch point position information of the touch key is effective according to the actual touch effective area information 3 of the touch key, so that the input accuracy of the touch key can be improved.
In some embodiments, when the touch confirmation method is applied to a soft keyboard, firstly, theoretical touch effective area information 1 of each touch key is adjusted according to effective touch point average position offset information of a certain touch key, and actual touch effective area information 3 of each touch key is obtained; then, according to the user touch position, it is determined which key is pressed, and the specific method may be: receiving each touch key induction information of the soft keyboard, and judging whether the touch key is touched according to each touch key induction information of the soft keyboard, for example: when the touch key is not touched, the working surface of the touch key is connected with a high-frequency signal; when the touch key is touched, the fingers and the working surface form a coupling capacitor under the action of a human body electric field, the fingers can absorb a very small current, the current flows out from the electrodes at the four corners of the working surface respectively, the current flowing through the four electrodes is proportional to the distance between the fingers and the contact position of the working surface, the contact position of the fingers and the working surface can be obtained according to the proportion of the four currents, and therefore which key is pressed is judged.
Optionally, as shown in fig. 1, fig. 2 and fig. 4, before adjusting the theoretical touch valid area information 1 of the touch key according to the average touch point position offset information of the touch key, the touch confirmation method further includes:
step S100: obtaining theoretical touch point position information 5 of the touch key and obtaining a plurality of effective touch point position information of the touch key;

step S120: obtaining average position offset information of effective touch points of the touch key according to the position offset information of the effective touch points of the touch key;
step S130: average positional deviation information of valid touch points of the touch key is stored.
Illustratively, theoretical touch point position information 5(X, Y) of the touch key is acquired, 4 valid touch point position information (X1, Y1), (X2, Y2), (X3, Y3), (X4, Y4) of the touch key is acquired, position offset information (X1-X, Y1-Y), (X2-X, Y2-Y), (X3-X, Y3-Y), (X4-X, Y4-Y) of the 4 valid touch points of the touch key is acquired, respectively, according to the theoretical touch point position information 5 of the touch key and the 4 valid touch point position information of the touch key, and average position offset information of the valid touch points of the touch key is acquired according to the position offset information of the 4 valid touch points of the touch key, thereby facilitating the acquisition of the average position offset information of the valid touch points of the touch key in step S200.
When different operators input, because different operators have different input habits, average position offset information of effective touch points of touch keys operated by different operators has difference, so that the input accuracy of the touch keys is not high.
It is understood that the average position deviation information of the effective touch points of the touch keys corresponds to the average position deviation information of the effective touch points of the touch keys in a one-to-one correspondence mode, and can be identified through a user name and a password or through fingerprints.
It is understood that the position information of the plurality of effective touch points of the touch key may be stored for the touch screen input device according to the previous operation record of the operator.
Optionally, as shown in fig. 1, fig. 2, and fig. 5, before adjusting the theoretical touch valid area information 1 of the touch key according to the offset average position offset of the valid touch point of the touch key, the touch confirmation method further includes:

step S180: updating the average position offset information of the effective touch points according to the position offset information of the effective touch points of the touch keys;
step S190: average positional deviation information of valid touch points of the touch key is stored.
Illustratively, the theoretical touch point position information 5 of the touch key is (X, Y), and the valid touch point position information 6 of the touch key is (X1, Y1), then the position offset information of the valid touch point of the touch key can be obtained as (X1-X, Y1-Y) according to the theoretical touch point position information 5 of the touch key and the valid touch point position information 6 of the touch key, and the average position offset information of the valid touch point is updated according to the position offset information of the valid touch point of the touch key, thereby facilitating the step S200 to obtain the average position offset information of the valid touch point of the touch key.
