Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, when a user writes on a touch screen by using a stylus, in order to facilitate writing, a side surface of a hand holding the stylus is supported on the touch screen, and a support point of the side surface of the hand on the touch screen also has writing traces, which affect writing of the stylus.
In the prior art, in order to avoid the influence of the supporting point of the hand on the writing of the stylus when the stylus is used for writing, the technical scheme is adopted to realize the separation of the writing of the stylus and the writing of the hand, and the writing of the stylus or the writing of the hand is distinguished by distinguishing the touch signal of the stylus from the touch signal of the hand.
However, in the prior art, when the stylus pen writes, the touch signal of the hand is shielded, and when the stylus pen writes, the touch signal of the stylus pen is shielded, so that the stylus pen and the hand cannot write at the same time. Like this, when the user needed stylus and hand to write simultaneously on the touch-sensitive screen, for example, the user used the in-process of stylus writing on the touch-sensitive screen, when needing to write on the touch-sensitive screen through the hand, still can shield the touch signal of hand, can't satisfy user's demand, and user experience is poor.
Therefore, to solve the problems existing in the prior art, the present application proposes: when the stylus pen writes on the touch screen, according to the characteristics of the side surface of the hand and the habit of the user writing, the shape of the side surface of the hand and the touch area of the touch screen is different from the shape of the touch area when the stylus pen writes on the touch screen and the shape of the touch area when the hand writes on the touch screen.
For example, when the side surface of the hand is supported on the touch screen, the contact area between the side surface of the hand and the touch screen is large, and the side surface of the hand is bent to a certain degree due to the pen-holding posture of the hand, so that the shape of the touch area formed on the touch screen by the side surface of the hand has a certain arc, and has a certain length and width. When a finger touches the touch screen, the contact area between the finger and the touch screen is small, and the shape of a touch area formed on the touch screen is similar to an ellipse.
Therefore, when the stylus pen writes on the touch screen, whether the shape of the touch area in the touch screen is the shape of the side of the hand and the touch area of the touch screen can be determined according to the shape of the touch area, the shape of the touch area in the touch screen is the shape of the side of the hand and the touch area of the touch screen, a touch signal when the side of the hand touches the touch screen is shielded, and a response is made to the touch signal (for example, the touch signal when the hand writes on the touch screen) when the shape of the touch area in the touch screen is not the shape of the side of the hand and the touch area of the touch screen. The touch signal of the hand during non-writing is only shielded, for example, the touch signal of the hand during the side face of the hand touching the touch screen, so that the touch signal of the hand during writing is responded, the simultaneous writing of the stylus and the hand is realized, and the user experience is improved.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The features of the embodiments and examples described below may be combined with each other without conflict between the embodiments.
Fig. 2 is a flowchart illustrating a touch processing method according to an embodiment of the present application. The execution subject of the method in this embodiment may be an electronic device, a server, or the like. The method in this embodiment may be implemented by software, hardware, or a combination of software and hardware. As shown in fig. 2, the method may include:
s201, when the first-type touch device and the second-type touch device touch the touch screen, obtaining a touch image corresponding to the first-type touch device.
The touch area of the first type of touch device in the touch screen in the touch image is different from the values of the pixel points in other areas.
In this step, the first type of touch device is a hand, the second type of touch device is a stylus,
for example, when a user holds a stylus pen in his/her hand and prepares to write on the touch screen, the side of the hand and the tip of the stylus pen may contact the touch screen at the same time due to different writing habits of the user, or the side of the hand of the user may contact the touch screen first and then the tip of the stylus pen may contact the touch screen. Or, the stylus pen is writing on the touch screen, and then the hand is also in contact with the touch screen, so that when the hand and the pen point of the stylus pen are in contact with the touch screen at the same time, because the touch signal generated when the pen point of the stylus pen is in contact with the touch screen can be recognized, the touch image corresponding to the hand can be acquired.
Although the touch signal when the hand is in contact with the touch panel can be recognized, it is not possible to recognize whether the touch signal is a touch signal when the hand is writing or a touch signal when the side surface of the hand is supported on the touch panel. Accordingly, a touch image corresponding to the hand is acquired, and whether the touch signal is a touch signal when the hand is writing or a touch signal when the side of the hand is supported on the touch screen is determined from the touch image, thereby determining whether to respond to the touch signal.
The touch image comprises a touch area and a non-touch area of a hand in the touch screen, and the touch area and the non-touch area are distinguished through values of pixel points.
Optionally, the touch image may be a grayscale image, for example, the touch image is a binary image in which the value of the pixel point in the touch region may be 1, and the value of the pixel point in the non-touch region may be 0, for example.
Optionally, one possible implementation scheme of S201 is: and obtaining a touch image corresponding to the first type of touch device according to the touch signal of the first type of touch device to the touch screen.
Specifically, when any part of the hand touches the touch screen, for example, a finger writes on the touch screen, or a side surface of the hand is supported on the touch screen, a touch module of the touch screen detects the touch of the hand to obtain a touch signal, the touch signal may be, for example, coordinates of a corresponding point in a touch area, or a pressing pressure value, a voltage value, and the like of the touch area, the touch module sends the touch signal to a processor of the electronic device, and the processor obtains a touch image corresponding to the hand according to the touch signal.
Or the touch module arranges the touch signal into a touch image and sends the touch image to a processor of the electronic device, so that the processor of the electronic device acquires the touch image corresponding to the hand.
S202, determining whether a touch signal of the first type of touch device touching the touch screen is responded according to the touch image.
In this step, the touch image includes a touch area and a non-touch area of the hand on the touch screen, for example, when a finger writes on the touch screen, the touch image corresponding to the finger is as shown in fig. 3, where area 1 in fig. 3 is the touch area of the finger on the touch screen, and the other areas are the non-touch areas. When the side surface of the hand is supported on the touch panel, a touch image corresponding to the side surface of the hand is shown in fig. 4, where an area 2 in the figure is a touch area when the side surface of the hand is supported on the touch panel. And comparing the shape of the touch area contained in the touch image with the shape of a preset invalid touch area, namely comparing the shape of the touch area contained in the touch image with the shape of the touch area formed when the side face of the hand is supported on the touch screen, and determining whether the shape of the touch area contained in the touch image is the shape of the touch area formed when the side face of the hand is supported on the touch screen, thereby determining whether the touch signal of touching the touch screen by the hand is responded.
A shape of a touch area formed when a side of a hand is supported on the touch screen, not responding to a touch signal of the hand touching the touch screen; otherwise, in response to a touch signal of a hand touching the touch screen, for example, when a finger writes over the touch screen, the written contents are displayed on the touch screen.
In the touch processing method provided by this embodiment, when a first-type touch device and a second-type touch device touch a touch screen, a touch image corresponding to the first-type touch device is obtained, where values of pixel points in a touch area of the first-type touch device in the touch screen and values of pixel points in other areas in the touch image are different; determining whether a touch area of a first type touch device in the touch screen is a preset invalid area or not according to the shape of the touch area of the first type touch device in the touch screen in the touch image, and not responding to a touch signal of a second type touch device when the touch area of the second type touch device in the touch screen is the preset invalid area; when the touch area of the second type touch device in the touch screen is not a preset invalid area, responding to the touch signals of the second type touch device instead of not responding to all the touch signals of the second type touch device. Therefore, the first-type touch device and the second-type touch device can write at the same time, and user experience is improved.
Fig. 5 is a flowchart illustrating a touch processing method according to another embodiment of the present application. As shown in fig. 5, on the basis of the embodiment shown in fig. 2, the method of the present embodiment includes:
s501, when the first type of touch device and the second type of touch device touch the touch screen, obtaining a touch image corresponding to the first type of touch device.
In this step, S201 may be referred to for a specific implementation manner of S501, and details are not described here.
S502, inputting the touch image into a preset image recognition model, and obtaining the result of the image recognition model for outputting whether to respond to the touch signal of the first type of touch device touching the touch screen or not according to the shape of the touch area in the touch image.
In this step, the preset image recognition model is obtained by training the image recognition model according to the corresponding touch image when the side surface of the hand is supported on the touch screen. Next, the image recognition model will be described as a convolutional neural network model. The training process of the convolutional neural network model is as follows:
the method includes the steps of collecting a corresponding touch image when the side face of the hand supports on the touch screen, for example, obtaining the corresponding touch image when the side face of the hand supports on the touch screen when a user writes on the touch screen by holding a stylus with the hand, or obtaining the corresponding touch image when the side face of the hand supports on the touch screen downloaded from a website, and obtaining a training data set.
It should be noted that, since the pen holding habits of different users are different, the shapes of the touch areas when the side surfaces of the hands of the users are supported on the touch screen are different, and thus the corresponding touch images are different. Also, the shape of the touch area when the side of the hand is supported on the touch screen is related to the age of the user. Therefore, when collecting a touch image corresponding to a touch screen in which a side surface of a hand is supported, it is necessary to collect a touch image corresponding to a touch screen in which a side surface of a hand is supported by a different user or a different pen holding habit.
Then, the corresponding touch image when the side face of each hand in the training data set is supported on the touch screen is processed, so that the touch area of the side face of the hand supported on the touch screen can be distinguished from other areas, and the shape characteristic of the touch area of the side face of the hand supported on the touch screen is obtained. For example, the corresponding touch image when the side of each hand is supported on the touch screen is arranged as a binary image having a uniform image size. The value of the pixel point in the touch area may be 1, for example, and the value of the pixel point in the non-touch area may be 0, for example, so that the shape of the touch area in the touch image is determined according to the value of the pixel point.
Inputting the gray level image corresponding to the touch image corresponding to the side surface of each hand supported on the touch screen into the convolutional neural network model, and training the convolutional neural network model to obtain the preset convolutional neural network model. The preset convolutional neural network model outputs a result indicating whether to respond to the touch signal of the first type of touch device touching the touch screen.
When a touch pen writes on the touch screen and a hand touches the touch screen, a touch image corresponding to the hand is obtained, and after gray processing is carried out on the touch image, a gray touch image is obtained. And inputting the gray scale touch image into a preset convolution neural network model. And the preset convolution neural network model acquires the shape of the touch area according to the value of the pixel point in the gray-scale touch image, and outputs a result indicating whether to respond to the touch signal of the hand touch screen or not according to the shape of the touch area.
Optionally, when recognizing that the shape of the touch area in the grayscale touch image is the shape of the touch area formed by the manual side support on the touch screen, the preset convolutional neural network model outputs a result indicating that the touch information of the hand touching the touch screen is not responded.
When recognizing that the shape of the touch area in the gray-scale touch image is not the shape of the touch area formed on the touch screen by manual side support, the preset convolutional neural network model may be a result of writing a finger on the touch screen and outputting touch information indicating a response to the touch of the hand on the touch screen.
In this embodiment, the preset image recognition model is obtained by training the touch image including the shape of the preset invalid touch area, so that the shape of the touch area of the first type touch device in the touch image in the touch screen can be accurately and quickly recognized through the preset image recognition model, and when the touch area of the second type touch device in the touch screen is the preset invalid area, the touch signal of the second type touch device is not responded; when the touch area of the second type touch device in the touch screen is not a preset invalid area, responding to the touch signals of the second type touch device instead of not responding to all the touch signals of the second type touch device. Therefore, the first-type touch device and the second-type touch device can write at the same time, and user experience is improved.
The embodiment shown in fig. 5 adopts an artificial intelligence method to identify the shape of the touch area in the touch image through a preset image identification model, so as to output a result indicating whether to respond to the touch signal of the first type of touch device touching the touch screen. Optionally, the shape of the touch area in the touch image may be identified by a non-artificial intelligence method, which is not described herein again.
It should be noted that, on the basis of any of the above embodiments, one possible implementation manner of S201 is: when the first type of touch device and the second type of touch device touch the touch screen, not only the touch image corresponding to the first type of touch device is obtained, but also the identifier of the touch image corresponding to the first type of touch device is obtained, and the identifier is used for uniquely identifying the touch image corresponding to the first type of touch device.
For example, when the stylus touches the touch screen, the side of the hand is supported on the touch screen, and a touch image corresponding to the side of the hand supported on the touch screen and the identifier of the touch image are acquired. The mark can be in the form of numbers, letters or the like.
Optionally, when the first type of touch device and the second type of touch device touch the touch screen, a touch device belonging to the second type of touch device also touches the touch screen, and at this time, the number of touch devices belonging to the second type of touch device touching the touch screen is greater than 2. At this time, the touch images of different touch devices belonging to the second type of touch device can be distinguished through the identifiers of the touch images.
Optionally, when the number of the touch devices belonging to the second type of touch device touching the touch screen is greater than 2, the identifier of the touch image corresponding to each touch device belonging to the second type of touch device is related to the order in which the touch devices touch the touch screen in the second type of touch device.
For example, when the stylus touches the touch screen, the side of the hand is supported on the touch screen, and a touch image corresponding to the side of the hand supported on the touch screen is obtained, and the identifier of the touch image is, for example, 01. At this time, when the stylus pen is writing on the touch screen, and the user writes on the touch screen with a finger, a touch image corresponding to the finger is acquired, and the identifier of the touch image is 02, for example.
Fig. 6 is a schematic structural diagram of a touch processing device according to an embodiment of the present application. As shown in fig. 6, the apparatus of the present embodiment includes: an acquisition module 61 and a determination module 62. Wherein the content of the first and second substances,

and a determining module 62, configured to determine whether to respond to a touch signal of the first type touch device touching the touch screen according to the touch image.
