fig. 2 is a flow chart of touch writing in an Android system according to a specific embodiment of the present invention.
Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
The touch of the IFP product has two paths of touch output, one path is accessed to a mainboard of an Android system, the other path is accessed to an OPS module (namely a Windows system), the output of the two paths of touch signals can be independently controlled, and by utilizing the characteristic, referring to the figure 1, the invention realizes a method for accelerating the Window writing effect, which comprises the following steps:
if the currently running system is a Windows system, when a user opens the whiteboard software of the Windows system and selects a pen, the whiteboard software of the Windows system synchronously sends a signal for starting writing and configuration information (namely handwriting) of the pen to the Android system; the whiteboard software of the Android system synchronizes the configuration information of the pen, enters an acceleration mode, opens an acceleration writing interface with a transparent background and displays the acceleration writing interface on the whiteboard software of the Windows system;
when writing, the whiteboard software of the Android system and the Windows system simultaneously responds to the touch information of the user, and the user sees the user writing handwriting displayed on the accelerated writing interface of the Android system;
and when the trigger condition is met, clearing the user writing handwriting displayed on the accelerated writing interface of the Android system, wherein the user sees the user writing displayed by the whiteboard software of the Windows system.
