Detailed Description
The technical solution of the present invention will be explained below with reference to the accompanying drawings.
As shown in FIG. 1, the invention provides a handwriting display method based on dual systems, which comprises the following steps:
S1, when the writing software of the second system is started, sending a starting instruction to the first system through the second system, and starting the transparent writing layer in the first system according to the starting 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 systems. In one exemplary 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 handwriting drawing is performed through writing software of the second system, the handwriting display process needs to be displayed after HMDI encoding, transmission and HDMI decoding. In order to accelerate handwriting display, when the writing software of the second system is started, a starting instruction can be sent to the first system through the second system, and a transparent writing layer is started at the first system. Since the writing software of the second system is started first and the transparent writing layer is started later, the transparent writing layer is covered on the writing software of the second system. Moreover, since the transparent writing layer is activated by the first system, that is, the background of the transparent writing layer is transparent, the user cannot perceive the existence of the transparent writing layer of the first system, and cannot perceive the activation process.
S2, executing handwriting drawing operation on the transparent writing layer according to the detected touch event to obtain first handwriting, and displaying the first handwriting on the transparent writing layer; wherein, the handwriting drawing process comprises a plurality of continuous handwriting drawing periods;
in this step, a touch event start instruction issued by the system may be detected, and if the touch event start instruction is detected, it is determined that a touch event occurs. Taking the android system as an example, when an ACTION _ DOWN command issued by the system is detected, it may be determined that a touch event occurs. In one embodiment, before the drawing operation is performed, handwriting property information may also be sent to the first system through the second system, and the handwriting property information may include information such as thickness of a handwriting line, definition of whether the handwriting line is a solid line or a dotted line, and/or color of the handwriting line. In a further embodiment, the second system may send the modified handwriting attribute information to the first system after receiving a modification instruction for the handwriting attribute information. After the first system obtains the handwriting attribute information, handwriting drawing operation can be executed according to the handwriting attribute information, and the first handwriting obtained through drawing is displayed on the transparent writing layer. In a further embodiment, the first handwriting may be rendered and the rendered first handwriting may be displayed on the transparent writing layer. If the handwriting attribute information acquired by the first system comprises color information of the handwriting lines, the first handwriting can be rendered according to the color information.
s3, in the process of executing handwriting drawing operation, periodically erasing the first handwriting drawn in the previous handwriting drawing period;
in one embodiment, a first handwriting drawn during a previous handwriting drawing cycle may be periodically erased by: firstly, timing can be started while executing handwriting drawing operation; when the timing reaches the handwriting drawing period, the first handwriting drawn in the handwriting drawing period can be erased, and the timing is restarted. That is, in the 2 nd handwriting drawing period, the handwriting drawn in the 1 st handwriting drawing period can be erased, in the 3 rd handwriting drawing period, the handwriting drawn in the 2 nd handwriting drawing period can be erased, and so on.
When the transparent writing layer is used for writing, the first system can start a timer to periodically and continuously erase the writing handwriting of the first system, the periodic interval is short, so that a small segment of handwriting can be seen to move along with the fingertip, and the small segment of handwriting can be called as a small tail for short. When the different systems write simultaneously in the dual systems, the writing handwriting can not overlap. The reason for non-overlapping of dual-system handwriting is that there are multiple dimensions, and if one of the dimensions is inconsistent, the handwriting cannot be completely overlapped. For example, the writing algorithms of the dual systems need to be consistent, the written Bezier curve algorithms need to be consistent, the sampling rates of the systems to the touch points need to be consistent, the frequencies of the touch points reported by the systems need to be consistent, and other dimensions. By periodically erasing the first handwriting, the problems can be solved, the complicated handwriting synchronization is avoided, and the complexity of the handwriting synchronization is reduced. The handwriting of the first system follows the fingertip movement by a small length as the finger moves, as shown in fig. 2.
s4, executing handwriting drawing operation on the writing interface of the writing software according to the touch event to obtain a second handwriting, and displaying the second handwriting on a writing layer of a second system;
This step may be performed while step S2 is being performed. In the step, when the handwriting drawing operation is executed, the handwriting drawing can be carried out according to the predefined handwriting attribute information. Before executing the handwriting drawing operation, a modification event of the handwriting attribute information can be detected, and if the modification event is detected, the handwriting drawing is carried out according to the modified handwriting attribute information; otherwise, handwriting drawing can be performed according to default handwriting attribute information.
By executing the steps S2 to S4, when the user performs touch writing, the two systems simultaneously process the touch event and draw handwriting at the same time; the user opens the writing software of the second system and then opens the transparent writing layer of the first system, so that the writing handwriting of the first system can be completely covered on the handwriting of the second system, the user can perceive the handwriting of the transparent writing layer of the first system and cannot perceive the writing handwriting of the second system when writing, but the user can think that the user is always the writing software of the second system when using the writing software of the first system because the writing layer of the first system is transparent; replacing the writing of the second system with the writing of the first system speeds up the handwriting display because the display of the first system does not require the delay of HDMI codec, transmission, or even encryption and decryption. A split view of a dual system based handwriting drawing operation is shown in fig. 3. In fig. 2, the dark patterns represent writing on the transparent writing layer of the first system, and the light patterns represent writing on the writing software of the second system. The transparent writing layer is overlaid on the writing software of the second system.
And S5, after the touch event is detected to be finished, if the handwriting drawing operation on the writing software is finished, erasing the remaining first handwriting.
When a user writes from a pen-down state to a pen-up state, the first system and the second system both write at the same time, the user senses that the first system writes, and when the user lifts the pen, the first system can remove the drawn handwriting and restore the transparent state without the handwriting; when the handwriting of the first system disappears, the user sees the handwriting which is already drawn by the second system, and the user cannot perceive the process of the disappearance of the handwriting of the first system because the handwriting of the two systems is completely overlapped. Whether the touch event is ended may be determined by detecting a touch event end instruction. When the touch event ending instruction is detected, the touch event can be judged to be ended, otherwise, the touch event is judged not to be ended. Taking the android system as an example, the ACTION _ UP event may be detected, and if detected, it may be determined that the touch event is ended, otherwise, it is determined that the touch event is not ended.
it is worth mentioning that the longer the period of the timer is, the slower the small tail disappears, and the longer the length of the presented small tail is, so that the length of the period of the timer is short, and the length of the small tail is directly influenced. If the small tail is too short, the writing speed of the second system may not be as fast as that of the first system, so that the handwriting of the two systems has a blank area in the writing process. Therefore, the length of the handwriting drawing period may be set to a value larger than the time delay of the second system for performing handwriting display with respect to the first system.
this scheme draws through dual system simultaneous handwriting to the acceleration of handwriting drawing display process is accomplished to the mode of fast taking slowly (first system takes the second system), through drawing and showing on the transparent layer of writing, and clear away the handwriting on the transparent layer of writing after handwriting drawing finishes, the handwriting that shows the second system completely carries out other operations with convenience of customers to second system handwriting, the handwriting need not to pass through HDMI when showing and compiles decoding and transmission delay, the time delay of handwriting display in-process has been reduced.
