Method and system for testing handwriting writing delay

Abstract

The invention provides a handwriting writing delay test method, which comprises the following steps of: S1, connecting equipment, opening equipment software, starting a screen recording function, recording a video, and writing on the equipment software at a constant speed; s2, acquiring a recorded video A, uploading the recorded video A to a server, intercepting the video A, and only reserving a video B written at a constant speed; s3, acquiring a frame rate F and recording time T by acquiring detailed information of a video B; s4, amplifying the video B to N times by using a player tool to obtain a video C; s5, analyzing the video C into pictures P1, P2... Pn according to the frame rate, S6, traversing whether the pictures P1, P2... are blank or not, and if the video is blank, recording the number V of the blank pictures; s7, calculating delay time through a formula that time = distance / speed; and finally outputting a test report. The test result is accurate and reliable, and a reliable data source is provided for performance optimization.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a handwriting delay testing method and system. Background technique [0002] Online education is becoming more and more popular, and it is more and more urgent to move teaching from classrooms to online; in classrooms, teachers impart knowledge through blackboards; online education, teachers use whiteboards to communicate and interact with students; conference software is used in enterprises The application is also becoming more and more extensive. If you want to achieve anytime, anywhere, in order to better assist users in efficient communication and connection, the whiteboard is also an indispensable tool. [0003] Disadvantages of the prior art: Handwriting writing on the whiteboard is affected by various reasons such as network, hardware, software, etc., and there is a problem of delay in handwriting writing. So what is the duration of this delay, and what is ...

Problems solved by technology

[0003] Disadvantages of the existing technology: the handwriting on the whiteboard is affected by various factors such as the network, hardware, software, etc., and there is a problem of handwriting delay

So what is the length of this delay, what is the probability, it is impossible to accurately determine

At present, it can only be judged by the senses, and the length of the delay can be roughly inferred. The specific number cannot be tested; and each test is manually detected, which is too subjective, which is not conducive to providing reference indicators for development and optimization.
