Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the description of the present application, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present application. In the description of the application, the meaning of "a plurality" is two or more, unless specifically stated otherwise.
The terms first, second and the like in the description and in the claims and in the above-described figures, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented, for example, in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such article or apparatus, but may include other steps or elements not expressly listed or inherent to such article or apparatus.
The description includes reference to the accompanying drawings, which form a part of the detailed description. The drawings illustrate diagrams according to exemplary embodiments. These embodiments, which may also be referred to herein as "examples," are described in sufficient detail to enable those skilled in the art to practice the embodiments of the claimed subject matter described herein. Embodiments may be combined, other embodiments may be utilized, or structural, logical, and electrical changes may be made without departing from the scope and spirit of the claimed subject matter. It should be appreciated that the embodiments described herein are not intended to limit the scope of the subject matter, but rather to enable one skilled in the art to practice, make and/or use the subject matter.
With the development of touch technology, more and more electronic devices perform man-machine interaction in a touch mode, taking an active touch pen as an example, in the prior art, the active touch pen is mainly used for measuring the force applied by a writer through a sensor, converting data obtained by measurement of the sensor into pressure sensing data, then sending the pressure sensing data to the touch device through Bluetooth, and converting the pressure sensing data into handwriting lines with different thicknesses by the touch device for display. The higher the pressure sensing stage number of the active stylus, namely the higher the sensitivity of the stylus to pressure, the more obvious the line thickness change is along with the force change of the user during writing, and the better the user experience is.
In the prior art, in the use process, when a touch pen uses Bluetooth to perform data transmission, the anti-interference capability is poor in a complex environment, and the phenomenon of delayed transmission and even frame loss can occur, so that the display handwriting line of the touch device is delayed, and the user experience is poor. The specific sources are as follows:
(1) The Bluetooth and Wi-Fi signals can interfere with each other, and the Bluetooth and Wi-Fi signals mainly use a 2.4GHz frequency band, so that when the Bluetooth and Wi-Fi signals are simultaneously started, the data throughput of the Bluetooth can be rapidly reduced, equipment pairing is difficult, wi-Fi is intermittently interrupted, and a network is limited;
(2) The touch pen is often provided with functions of an empty mouse, including a page turning key, a shortcut key, a rubber key and other functional keys, so that not only pressure sensing data but also functional key data are required to be sent through Bluetooth, the complexity of data analysis is increased, the analysis time is occupied, and the response efficiency is reduced;
(3) The touch pen is used for reporting pressure sensing data through Bluetooth for air transmission, and is easy to be shielded by an object, so that the pressure sensing data cannot be matched with position information reported by an infrared touch frame or a capacitive touch screen, and a data frame is delayed or even lost.
Therefore, the display of handwriting lines of the conventional touch control equipment is delayed, so that the user experience is poor, and the requirement of the current man-machine interaction on the real-time information display is difficult to meet.
Based on the above problems, the embodiments of the present application provide an information display method, a touch device, and a storage medium, where a driver is installed in an operating system of the touch device, and in a data transmission process, the driver receives position information sent by an infrared touch frame or a capacitive touch screen and pressure sensing data sent by a stylus, and when delay or frame loss occurs, the driver monitors and predicts the pressure sensing data in real time, and after integration, the pressure sensing data is sent to the operating system, and is analyzed by the operating system and then displayed. Therefore, when the user writes, the pressure sensing data can be transmitted stably in real time, the touch equipment can display the input information of the user in real time, and the user experience is improved.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

(2) The N frames of pressure sensing data are gradually decreased from frame to frame along with the receiving time;
(3) The N-frame pressure-sensitive data is not incremented or decremented from frame to frame with the time of receipt, i.e., the size of the N-frame pressure-sensitive data fluctuates with the time of receipt.
S302, judging whether the change rule is increasing or decreasing from frame to frame.
And S303, when the change rule is not increasing from frame to frame or decreasing from frame to frame, determining that the average value of the last received pressure sensing data is the pressure sensing data at the current moment.

In another embodiment, when the change rule of the pressure sensing data is increasing from frame to frame or decreasing from frame to frame, each frame of the pressure sensing data received last time, that is, N frames of the pressure sensing data, is obtained, and the difference value between each frame of the pressure sensing data and the pressure sensing data of the adjacent frame is obtained. Wherein (N-1) differences can be obtained from the N frames of pressure-sensitive data, illustratively M j Representing the difference value, wherein j represents the difference value serial number, and the first difference value M 1 The second difference M is the difference between the second frame pressure sensing data and the first frame pressure sensing data 2 Is the difference value between the third frame pressure sensing data and the second frame pressure sensing data, the N-1 difference value M N-1 Is the difference between the N frame pressure sensing data and the N-1 frame pressure sensing data.
