Problems solved by technology

In practice, it is found that when there are many test questions that need to be extracted or the test questions that need to be extracted are relatively complex (for example, geometry questions contain complex geometric figures), it takes a long time to extract by hand, especially hand-written excerpts may lead to Incomplete or wrong excerpts, etc. If the excerpted test questions are incomplete or wrong, the beneficial learning effect brought by the excerpt will be greatly reduced, thereby reducing the learning efficiency in the later period

Embodiment 1

[0073] see figure 2 , figure 2 It is a schematic flowchart of a method for extracting test questions based on a smart pen disclosed in an embodiment of the present invention. Such as figure 2 As shown, this method for extracting test questions based on smart pens can include the following steps:

[0074] 201. When the smart pen is in the test question extraction mode, project a dominant frame onto the test question face, and the explicit frame is used to frame the test questions to be extracted on the test question face face.

[0075] In the embodiment of the present invention, it may be preferred that the smart pen is physically disconnected from the electronic device, so as to facilitate holding the smart pen. At this time, the smart pen and the electronic device may be in a network connection state or in a network disconnection state, which is not specifically limited here.

[0076] As an optional implementation, in the embodiment of the present invention, the smart ...

Embodiment 2

[0093] see image 3 , image 3 It is a schematic flowchart of another method for extracting test questions based on a smart pen disclosed in the embodiment of the present invention. Such as image 3 As shown, this method for extracting test questions based on smart pens can include the following steps:

[0094] 301. When the smart pen is in the test question extraction mode, the smart pen detects whether the current vertical distance between it and the test question is less than or equal to the preset distance, if yes, perform steps 302 to 305; if not, perform steps 309 to 311 .

[0095] 302. The smart pen determines a target size matching the above-mentioned current vertical distance from multiple preset sizes.

[0096] 303. The smart pen projects an explicit frame with the above-mentioned target size to the surface where the test questions are located, and the explicit frame is used to frame the test questions to be extracted on the surface where the above-mentioned test...

[0113] see Figure 4 , Figure 4 It is a schematic flowchart of another method for extracting test questions based on a smart pen disclosed in the embodiment of the present invention. Such as Figure 4 As shown, this method for extracting test questions based on smart pens can include the following steps:

[0114] Wherein, for the detailed description of steps 401 to 411, please refer to the description of steps 301 to 311 in Embodiment 2, which will not be repeated in this embodiment of the present invention.

[0115] Wherein, in the embodiment of the present invention, after step 408 is executed, steps 412 to 413 may also be executed.

[0116] 412. The smart pen, in the voice search question mode included in the question search mode, obtains the input voice message used to describe the test question to be extracted in the test question image.

[0117] The test question image can include multiple test questions to be extracted, and the test questions to be extracted that ...

Abstract

A method, system and smart pen for extracting test questions based on a smart pen, comprising: when the smart pen is in the test question extracting mode, projecting the explicit frame used to frame the test questions to be extracted on the face where the test questions are located to the face where the test questions are located, and The area framed by the dominant frame is photographed to obtain the test question image. After the test question image is obtained, the smart pen stores the test question image in the designated storage area, and when the smart pen is connected to the electronic device, it sends the test question image to the electronic device. The test question image in the storage area is designated, so that the electronic device archives the test questions to be extracted included in the test question image according to preset rules. Implementing the embodiment of the present invention can effectively improve learning efficiency.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a method and system for extracting test questions based on a smart pen, and the smart pen. Background technique [0002] In the process of learning, it is often necessary to extract the unintelligible or representative test questions, because the extracted test questions that are not understood can be easily consulted by others in the future, and the representative test questions can be used as important resources for subsequent review. So developing a good excerpt habit is very helpful for learning. In practice, it is found that when there are many test questions that need to be extracted or the test questions that need to be extracted are relatively complex (for example, geometry questions contain complex geometric figures), it takes a long time to extract by hand, especially hand-written excerpts may lead to If the excerpted test questions are incomplete or wrong, the b...
