Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a first embodiment of a writing touch recognition method based on an infrared touch screen according to the present invention, where the writing touch recognition method based on the infrared touch screen includes:
step S10, when the writing application is detected to be opened, collecting effective touch point data;
based on the current terminal application, the terminal is a terminal device with an infrared touch screen, and when a user uses the terminal, the writing application of the terminal, namely writing software based on touch, is started. In the current terminal application, when the writing application is detected to be opened, effective touch point data is collected based on the writing application. The touch point data is touch data based on touch operation performed by a user on an application page of the writing application after the current writing application is started, and the touch data is acquired in a touch point mode when the touch operation is embodied on a touch screen, so that the touch point data is acquired according to the touch operation data acquired after the current writing application is started. In addition, when acquiring touch point data of the current writing application, effective touch point data needs to be acquired, and a mode of judging whether the touch point data is effective is adopted, so that the content of judging that the touch operation is effective in the prior art is not repeated herein. Further, based on the opening operation of the current writing application, a preset driving layer special channel is opened to process the collected touch point data, that is, when the step of collecting effective touch point data is detected when the writing application is opened, the method further includes:
sending a writing delivery instruction to the infrared touch screen;
and opening a preset special channel of the driving layer based on the written delivery instruction.
When the writing application of the current infrared touch screen terminal is detected to be opened, a writing delivery instruction is sent to the infrared touch screen, wherein the writing delivery instruction sent to the infrared touch screen can be initiated through a related function based on the special delivery of the writing application in an application system of the current terminal, and the sending position can be defined as the touch point data acquisition function of the infrared touch screen for receiving. Therefore, according to the writing delivery instruction sent to the infrared touch screen, a preset driving layer special channel of the infrared touch screen terminal application system is opened, and in practical application, the preset driving layer special channel is a message transmission channel which is created in the terminal application system in advance and is from the infrared touch screen to a terminal system application software message layer.
Step S20, confirming whether the touch point data is writing data;
and confirming whether the touch point data is writing data or not according to the currently acquired touch point data, wherein in practical application, the touch point data is based on touch operation initiated by a current user on an infrared touch screen of the terminal. In this way, when confirming whether the touch point data formed based on the current touch operation is writing data, confirming with the touch track formed by the touch point data, namely confirming whether the touch point data is writing data, includes:
and connecting the touch point data to form a touch track, and confirming whether the touch point data is writing data or not according to the touch track.
According to currently collected touch point data, the touch point data are connected in a straight line to form a touch track, and then whether the collected touch point data are writing data or not is confirmed through the touch track, and further, when the data type is confirmed through the touch track, the confirmation mode can be confirmed based on whether a line formed by the touch track is a character stroke or not; in addition, whether a touch track formed by the touch point data is writing data or not can be confirmed based on the acquisition page and the acquisition position of the touch point data, and the acquisition page and the acquisition position can include but are not limited to a writing page and a writing position of a writing application in the infrared touch terminal.
Then, when confirming whether the touch point data is writing data based on the touch track formed by the touch point data, if the touch point data is not writing data, namely after the step of confirming whether the touch point data is writing data, the method further comprises the following steps:
and processing the touch point data by a terminal system when the touch point data is confirmed not to be writing data.
And when the touch track formed based on the touch point data confirms that the touch point data is not writing data, namely when the touch track is not a character stroke, processing the touch point data in a default message processing mode of the current terminal system, wherein the default message processing mode of the terminal system is a message processing step based on the current terminal system, the data layer related to the processing step comprises a system message processing layer and an application message layer, and then the touch point data is sent to the corresponding execution application based on the application message layer without passing through a started preset driving layer special channel.
And step S30, when the touch point data is confirmed to be writing data, delivering the touch point data to a preset driving layer special channel for processing.
Based on currently received touch point data, when the touch point data is confirmed to be writing data, the touch point data is delivered to a preset drive layer special channel according to an opened preset drive layer special channel, the touch point data is directly transmitted to a corresponding execution application for processing through the drive layer special channel, wherein the drive layer special channel is a special message channel from an infrared touch screen to a processing application based on the current terminal application, the delivered data in the channel is directly delivered to the corresponding function application for processing without being distributed by a terminal application system, for example, the touch point data currently used for the writing application is distributed to a drive layer after being packaged and analyzed through a message layer of the terminal when the touch point data is received by the infrared touch screen, and is transmitted to the writing application through the drive layer, but the touch point data is directly delivered to the writing application processing through the preset drive layer special channel .
In addition, in view of the problem of the terminal application, in order to avoid that the writing application crashes to cause the receiving failure of the touch operation of the terminal application, the running state of the current writing application needs to be fed back to the infrared touch screen, that is, the writing touch identification method based on the infrared touch screen further includes:
and sending a heartbeat signal to the infrared touch screen at a preset period.
In order to prevent abnormal situations such as software sudden crash, in a terminal application, a writing application for starting and processing relevant touch point data is notified to an infrared touch screen in a certain time interval in a heartbeat signal mode according to the running condition of the writing application so as to inform the touch screen to keep a data processing state for delivering the touch point data to a preset special channel of a driving layer to process currently, and when the infrared touch screen does not receive the heartbeat signal after exceeding the preset time interval, the infrared touch screen can be automatically restored to an original state, namely the preset special channel of the driving layer is closed to stop delivering the touch point data.
As described above, the method for recognizing writing touch on the infrared touch screen, which is based on the current writing application, determines the touch point data of the current writing application with the relevant touch recognition function in the current infrared touch screen terminal according to the operation processed by the special channel, further includes:
and when receiving a writing mode switching instruction, starting a writing touch recognition function.
According to the current terminal application, a user starts a writing mode switching instruction in related function setting, wherein the writing mode switching instruction is developed on the premise of improving the touch point data processing efficiency based on the current writing application and is implanted into a terminal system of the terminal in a functional form. Therefore, according to the operation of starting a writing mode switching instruction by a current user, when the writing mode switching instruction is received, a writing touch recognition function of a terminal system in the terminal is started, and based on the writing touch recognition function, a preset driving layer special channel is created so as to process touch point data of writing application.
In the embodiment, when a user performs writing operation through the infrared touch screen, the message of the writing operation is processed through a preset driving layer special channel to avoid passing through a terminal system operation layer, and the beneficial effect that the data processing efficiency is improved to avoid message loss during message reporting is achieved.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a second embodiment of the writing touch recognition method based on an infrared touch screen according to the present invention, where based on the first embodiment shown in fig. 2, the writing touch recognition method based on an infrared touch screen further includes:
step S40, when the writing application is detected to be dormant, counting the dormant time of the writing application;
and step S50, when it is determined that the sleep time is greater than a preset sleep time, closing the preset special channel of the driver layer.
In this embodiment, based on the operation that touch point data of a writing application in a current terminal application is processed through a preset special channel of a driving layer, a terminal application error caused by a terminal writing application failure is not avoided, and a monitoring operation needs to be performed based on an application state of the current writing application, where the monitoring operation is mainly defined as sleep monitoring. Therefore, according to the operation of the current writing application, when the writing application dormancy is detected, other application operations of the terminal application are considered, and the preset special channel of the driving layer is closed, so that the operation of other applications of the current terminal system is not influenced. Wherein, when determining the dormancy operation of the writing application, the writing application is confirmed with the writing stop time of the writing application, and the writing operation is determined by the acquisition operation of the touch point, therefore, the step of counting the dormancy time of the writing application when detecting the dormancy of the writing application comprises:
counting a vanishing time of the touch point data when the touch point data of the writing application cannot be detected;
and if the counted disappearance time is larger than the preset disappearance time, confirming that the writing application is dormant.
According to the operation condition of the writing application of the current terminal, when the touch point data of the writing application cannot be detected, confirming that the current writing application possibly stops operating, and thus counting the disappearance time of the touch point data of the writing application. According to the counted disappearance time, when the disappearance time is confirmed to be greater than a preset disappearance time, the writing application can be confirmed to be in a dormant state, wherein the preset disappearance time is a definable numerical value, and when the preset disappearance time is defined, the writing application can be set based on relevant application information of the writing application, such as an application type, an application range, and the like of the writing application. Therefore, the current touch point data delivery mode is determined according to the defined preset sleep time, the message writing processing efficiency of the terminal is improved, and the problem of the terminal application related to the touch point operation aging is reduced.
