Embodiment 1

[0036] The online assignment / examination input method based on papery handwriting provided by the present invention comprises the following steps:

[0037] Identify the question number, display the question corresponding to the question number on the display screen, and judge whether the question contains graphics that need to be drawn or filled:

[0038] If so, automatically generate the drawing area associated with the graphic on the smart tablet, and obtain the position of the stylus from the drawing area, present the position of the stylus on the display screen in real time, and then from the drawing area Obtain the answer based on paper handwriting with the stylus, and display the answer in real time on the graphics on the display screen to correspond to the graphics;

[0039] Otherwise, directly obtain the answer based on paper handwriting from the smart tablet, and display the answer in real time in the answer presentation area corresponding to the question on the displ...

Embodiment 2

[0052] The present invention provides a paper-based handwriting-based online assignment / examination input device corresponding to the input method in Embodiment 1, including:

[0053] A smart tablet, including an electromagnetic induction screen and an electromagnetic stylus, used to obtain handwritten question numbers and answers on the answer sheet covered on the electromagnetic induction screen;

[0054] The system terminal is connected with the smart tablet, and includes a display screen, which is used to obtain the question numbers and answers based on paper handwriting on the smart tablet, and display the question numbers and answers on the display in one-to-one correspondence with the questions on the system terminal screen; when it is judged that the question contains graphics that need to be drawn or filled, the drawing area associated with the graphics is automatically generated on the smart tablet, and the position of the stylus is obtained from the drawing area, and...

Abstract

The invention discloses an online work / exam inputting method and device based on paper writing. The method comprises the following steps: recognizing question numbers, displaying questions corresponding to the question numbers on a display screen, and judging whether the questions comprise graphs which require to be constructed or plotted or not; if the questions comprise the graphs which requireto be constructed or plotted, automatically generating a graph constructing region which is relevant to the graphs on an intelligent writing plate, acquiring the position of a writing pen in the graphconstructing region, displaying the position of the writing pen on the display screen in real time, then acquiring answers written with the writing pen from the graph constructing region, and displaying the answers on the display screen in real time and corresponding the answers to the graphs; and if the questions do not comprise the graphs which require to be constructed or plotted, directly acquiring answers based on paper writing from the intelligent writing plate, and displaying the answers an answer displaying region which correspond to the questions in the display screen in real time. The graphs in a graph constructing question or a graph plotting question can be automatically recognized, a user only needs to draw graphs and connect lines on an answer sheet, and results for graph drawing and line connection are automatically shown on a system terminal and are in one-to-one correspondence to the graphs of the questions.

Description

technical field [0001] The invention relates to the technical field of online education, in particular to an online assignment / examination input method and device based on paper handwriting. Background technique [0002] Many existing online homework examination learning systems can collect, record, and analyze students' learning data, reduce the burden of teachers' corrections, and improve teaching efficiency. The generation of big data is based on the complete electronic learning process. The input method is keyboard input or screen handwriting input. In the keyboard input, the input of many formulas and graphs of science subjects such as mathematics and science have become a big problem; although the method of direct input on the screen can input formulas and graphs, it has changed the teaching habits of teachers and students. It is based on the traditional paper-based handwritten answer method, and the input feeling is poor and the recognition accuracy is not high. The...
