Problems solved by technology

[0003] According to statistics, for Android systems that support screen handwriting, the delay from writing on the screen to displaying the handwriting generally reaches about 100ms. With the increase of writing content, the complexity of the screen increases, and the amount of data processed by the system per frame increases. , handwriting delay also increases significantly, resulting in handwriting sluggishness when writing, resulting in poor user experience

Embodiment Construction

[0029] see figure 1 As shown, a screen handwriting followability optimization system of the present invention, the optimization system includes an input optimization module and a drawing optimization module; the screen includes an electromagnetic screen or a capacitive screen, etc.;

[0030] The input framework of the existing Android system can be adapted to handle various types of input events. The basic process is that when the system starts, the input-related services will be initialized, and the EventHub object and InputReader and InputDispatcher threads will be created; when an input event occurs, the InputReader thread will read the event reported by the driver through the EventHub object and perform preprocessing ( For example, judge the event type, judge whether the button is long press, short press, etc.), and then hand it over to the InputDispatcher thread for processing; the InputDispatcher thread will make necessary judgments, such as whether the event can be inte...

Abstract

The invention provides a system for optimizing the screen handwriting following performance. The optimizing system comprises an input optimizing module and a drawing optimizing module. The input optimizing module is used for optimizing the tedious reading and distributing process procedure of an input event of an android system; in other words, an independent processing thread is built for a screen, and a screen coordinate event reported by a driver of the android system is directly processed through the independent thread. The drawing optimizing module is used for optimizing the bottom-layer memory allocation, data synthesis and display process procedure when the android system applies drawing; in other words, drawing processing of an application layer of the android system is transferred to a local layer of the android system to be achieved, an independent graph buffering area is applied to serve as canvas, the canvas is put to a hardware frame buffering area, and then coordinate data received through the canvas is drawn and displayed to the screen through a drawing engine SKIA. By means of the system, the input delay condition of the screen of the android system is improved, and the drawing speed can not be decreased along with improvement of the complexity of the content.

Description

technical field [0001] The invention relates to the technical field of Android systems, in particular to a method and system for optimizing screen handwriting followability. Background technique [0002] In recent years, tablet computers have continuously penetrated from personal entertainment terminals to education, business and other industries. Screen handwriting technology has been widely used in industry tablets. Among them, screen handwriting delay is a key indicator that affects the input experience. [0003] According to statistics, for Android systems that support screen handwriting, the delay from writing on the screen to displaying the handwriting generally reaches about 100ms. With the increase of writing content, the complexity of the screen increases, and the amount of data processed by the system per frame increases. , handwriting delay also increases significantly, resulting in handwriting sluggishness when writing, resulting in poor user experience.
