Detailed ways

The technical solution of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 , the present invention provides a dual system based handwriting display method, which may include the following steps:

S1, when the writing software of the second system is started, sending, by the second system, a startup instruction to the first system, and starting the transparent writing layer in the first system according to the startup instruction;

In one embodiment, the first system may be an operating system such as an Android system, an IOS system, or a Windows system, and the second system may also be one of the above systems. In a typical embodiment, the first system and the second system may both be Android systems. The writing software of the second system is the writing software installed in the second system. When the handwriting is drawn by the writing software of the second system, the handwriting display process needs to be displayed after HMDI encoding, transmission, and HDMI decoding. In order to speed up the handwriting display, when the writing software of the second system is started, a startup command can be sent to the first system through the second system, and a transparent writing layer is activated in the first system. Since the writing software of the second system is activated first, the transparent writing layer is activated, so that the transparent writing layer will overwrite the writing software of the second system. And, since the first system starts with a transparent writing layer, that is, the background is transparent, then for the user, It is impossible to perceive the existence of the transparent writing layer of the first system, and it is not aware of this startup process.

S2, performing a handwriting drawing operation on the transparent writing layer according to the detected touch event, obtaining a first handwriting, and displaying the first handwriting on the transparent writing layer; wherein the handwriting drawing process comprises several consecutive handwritings Drawing cycle

In this step, a touch event start command issued by the system may be detected, and if detected, a touch event is determined to occur. Taking the Android system as an example, when the ACTION_DOWN command issued by the system is detected, it can be determined that a touch event occurs. In an embodiment, the handwriting attribute information may also be sent to the first system by the second system before performing the drawing operation, and the handwriting attribute information may include the thickness of the handwriting line, the definition of the handwriting line being a solid line or a broken line, and/or Or information such as the color of the handwriting lines. In a further embodiment, the second system may transmit the altered handwriting attribute information to the first system after receiving the change instruction to the handwriting attribute information. After acquiring the handwriting attribute information, the first system may perform a handwriting drawing operation according to the handwriting attribute information, and display the drawn first handwriting on the transparent writing layer. In a further embodiment, the first handwriting can also be rendered and the rendered first handwriting displayed on the transparent writing layer. If the handwriting attribute information acquired by the first system includes the color information of the handwriting line, the first handwriting may be rendered according to the color information.

S3, during the execution of the handwriting drawing operation, periodically erasing the first handwriting drawn in the previous handwriting drawing period;

In one embodiment, the first handwriting drawn in the previous handwriting drawing period can be periodically erased by: first, timing can be started while the handwriting drawing operation is performed; when the timing reaches the handwriting drawing period, The first handwriting drawn during the handwriting drawing period can be erased and the timing can be restarted. That is, in the second handwriting drawing period, the handwriting drawn in the first handwriting drawing period can be erased, and in the third handwriting drawing cycle, the handwriting drawn in the second handwriting drawing period can be erased, thereby analogy.

When writing in the transparent writing layer, the first system can start a timer to periodically erase the writing handwriting of the first system, and the interval of the cycle is very short, so that the writing effect of the first system can be seen for a short period of time. The handwriting moves with the fingertips, and this small handwriting can be simply referred to as the "small tail". When different systems are simultaneously written in a dual system, the writing strokes may not overlap. Causing double system writing There are multiple dimensions for the reason that the handwriting does not overlap. As long as one of the dimensions is inconsistent, the handwriting cannot be completely overlapped. For example, the writing algorithm of the dual system should be consistent, the Bessel curve algorithm should be consistent, the sampling rate of the system should be consistent with the sampling rate of the touch points, and the frequency of the system reporting the touch points should be consistent. By periodically erasing the first handwriting, the above problem can be solved, complicated handwriting synchronization is avoided, and the complexity of handwriting synchronization is reduced. As the finger moves as shown in Figure 2, the handwriting of the first system follows the fingertip motion for a short length.

S4, performing a handwriting drawing operation on the writing interface of the writing software according to the touch event, obtaining a second handwriting, and displaying the second handwriting on a writing layer of the second system;

This step can be performed while performing step S2. In this step, when the handwriting drawing operation is performed, the handwriting can be drawn according to the predefined handwriting attribute information. Before performing the handwriting drawing operation, the modification event of the handwriting attribute information may also be detected. If detected, the handwriting is drawn according to the modified handwriting attribute information; otherwise, the handwriting drawing may be performed according to the default handwriting attribute information.

By performing steps S2 to S4, when the user performs touch writing, the two systems simultaneously process the touch event and draw the handwriting at the same time; since the user opens the writing software of the second system, the transparent writing layer of the first system is opened. Therefore, the writing handwriting of the first system will completely cover the handwriting of the second system. When the user writes, the natural handwriting is the handwriting of the first system transparent writing layer, and the writing handwriting of the second system is not perceived. However, due to the transparency of the first system's writing layer, the user will think that he is always using the writing software of the second system; the writing of the first system can replace the writing of the second system to speed up the handwriting display, because the first The display of the system does not require the delay of HDMI codec, transmission or even encryption and decryption. The split diagram of the handwriting drawing operation based on the dual system is shown in Fig. 3. In Fig. 2, the dark pattern represents the handwriting on the transparent writing layer of the first system, and the light color pattern represents the handwriting on the writing software of the second system. The transparent writing layer is overlaid on the writing software of the second system.

S5. After detecting the end of the touch event, if the handwriting drawing operation on the writing software is completed, the remaining first handwriting is erased.

When the user starts writing, the first system and the second system both write at the same time, the user perceives the writing of the first system, and when the user lifts the pen, the first system will clear the drawn handwriting. , restore the transparent state without handwriting; when the handwriting of the first system disappears, the user will see The second system has already drawn good handwriting. Since the handwriting of the two systems completely overlaps, the user does not perceive the process of the first system handwriting disappearing. Whether the touch event is ended can be determined by detecting a touch event end instruction. When the touch event end instruction is detected, it may be determined that the touch event ends, otherwise, it is determined that the touch event has not ended. Taking the Android system as an example, the ACTION_UP event can be detected. If detected, the touch event can be determined to end, otherwise, the touch event is not ended.

It is worth mentioning that the longer the period of the timer, the slower the small tail disappears, and the longer the length of the small tail appears, so the period of the timer directly affects the length of the small tail. If the small tail is too short, there may be cases where the writing speed of the second system cannot keep up with the writing speed of the first system, resulting in a blank area in the writing process of the two systems. Therefore, the length of the handwriting drawing period can be set to a value greater than the time delay of the second system to perform handwriting display with respect to the first system.

In this scheme, the handwriting is simultaneously drawn by the dual system, and the acceleration of the handwriting display process is completed by the fast belt slow (the first system with the second system), by drawing and displaying on the transparent writing layer, and after the handwriting is drawn. Clear the handwriting on the transparent writing layer, completely display the handwriting of the second system to facilitate the user to perform other operations on the second system handwriting. The handwriting does not need to pass HDMI codec and transmission delay when displaying, which reduces the delay in the handwriting display process. .

When the handwriting is drawn by the writing software of the second system, the handwriting display process needs to be displayed after HMDI encoding, transmission, and HDMI decoding. In order to speed up the handwriting display, when the writing software of the second system is started, a startup command can be sent to the first system through the second system, and a transparent writing layer is activated in the first system. Since the writing software of the second system is activated first, the transparent writing layer is activated, so that the transparent writing layer will overwrite the writing software of the second system.
