[0060] This application discloses a method, apparatus, electronic device, and storage medium for providing answer prompts, which improves the portability of answering exercises on electronic devices. This answer prompt method is applicable to electronic devices such as smartphones, laptops, tablets, and tutoring machines; however, this application does not limit its application to these devices. Detailed descriptions follow.
[0061] Please see Figure 1 , Figure 1 This is an example diagram illustrating an application scenario of a question-answering suggestion method disclosed in an embodiment of this application. For example... Figure 1 As shown, the electronic device displays questions to be answered, each question potentially including one or more sub-questions. The device also displays the original answer areas for each sub-question. Optionally, the electronic device includes a camera that can photograph the physical paper. The user can then answer the questions displayed on the physical paper.
[0062] Please see Figure 2 , Figure 2This is a flowchart illustrating a question-answering suggestion method disclosed in an embodiment of this application. This method can be applied to electronic devices such as smartphones, laptops, tablets, and tutoring machines, and is not specifically limited thereto. Figure 2 As shown, this method of providing answer hints may include the following steps:
[0063] 201. Identify the question type and number of questions to be answered.
[0064] Electronic devices can retrieve individual questions from a question database specified by the user in the quiz software. The question database can be stored on the electronic device or a server.
[0065] A question to be answered may include one or more questions; the electronic device identifies the question type of each question in the question to be answered and the number of questions in the question to be answered.
[0066] The question types can be multiple choice, fill-in-the-blank, or application questions, with no specific restrictions.
[0067] The number of questions in a question to be answered can be any positive integer, with no specific limit.
[0068] 202. Determine the corresponding physical answer area on the physical paper for each question based on the number and type of questions.
[0069] In some embodiments, the electronic device determines the number of physical answer areas corresponding to the questions to be answered based on the number of questions; the electronic device determines the size or area of each physical answer area based on the question type; and the electronic device assigns the position of each physical answer area on the physical paper based on the number of physical answer areas and the size or area of each physical answer area.
[0070] The questions to be answered include one or more questions, and one question can correspond to one entity's answer area.
[0071] In some embodiments, the electronic device may determine the number of physical answer areas corresponding to the questions on the physical paper based on the number of questions, for example, the number of physical answer areas on the physical paper may be equal to the number of questions included in the questions to be answered; and / or, the electronic device may determine the size or area of the physical answer area corresponding to each question included in the questions to be answered based on the question type; and / or, the electronic device may determine the spacing between each physical answer area and the position of each physical answer area on the physical paper based on the number of questions and the question type.
[0072] In some optional implementations, the question types include multiple-choice questions; the electronic device determines the physical answer area on the physical paper corresponding to the questions to be answered based on the number of questions and the question types, including: when the question type is multiple-choice, the electronic device determines the size of the physical answer area on the physical paper corresponding to the questions to be answered as a first size; the question types include application questions; the electronic device determines the physical answer area on the physical paper corresponding to the questions to be answered based on the number of questions and the question types, including: when the question type is application question, the electronic device determines the size of the physical answer area on the physical paper corresponding to each question in the question to be answered as a second size; the first size is smaller than the second size.
[0073] In some alternative implementations, the question type can be the answer type corresponding to each question. For example, the electronic device can acquire the standard answer corresponding to each question and identify the answer type corresponding to each standard answer. The answer type can be a single word, two words, three words, etc., without specific limitations. The electronic device can determine the size of the physical answer area corresponding to each question based on the answer types corresponding to each question in the question to be answered.
[0074] 203. Output the location of the physical answer area on the physical paper.
[0075] Electronic devices can output the location of the physical answer area on the physical paper through output methods such as virtual images, voice broadcasts, or text displays.
[0076] This application embodiment determines the corresponding physical answer area on the physical paper based on the identified question type and the number of questions included in the question to be answered, and outputs the position of the physical answer area on the physical paper. This allows the user to write their answer in the corresponding physical answer area on the physical paper according to the position of the physical answer area output by the electronic device, improving the standardization of the answer and reducing the difficulty of recognizing the written content.
[0077] Please see Figure 3 , Figure 3 This is a flowchart illustrating another question-answering suggestion method disclosed in an embodiment of this application. This method can be applied to any of the aforementioned electronic devices. Figure 3 As shown, the method includes the following steps:
[0078] 301. Identify the question type and number of questions to be answered.
[0079] 302. Obtain the first image of the physical paper.
[0080] In some embodiments, the electronic device can capture an image of the physical paper using its camera to obtain a first image. Specifically, the electronic device can capture an original image containing the physical paper, which may include other elements besides the physical paper. The electronic device captures the original image containing the physical paper to obtain an original image, and then performs object detection on the original image to obtain a first image of the physical paper from the original image. The first image is an image containing only the physical paper. That is, the electronic device can use an object detection algorithm to detect the position and size of the physical paper within the original image to obtain the first image of the physical paper.
[0081] Optionally, the electronic device may also receive a first image of the physical paper sent by other electronic devices; or, the electronic device may generate a first image of the physical paper when a first user operation is detected, wherein the first user operation may be an operation for inputting parameters of the physical paper, and the parameters of the physical paper may include the length, width, etc. of the physical paper.
[0082] 303. Identify the usable area of the physical paper based on the first image.
[0083] The usable area does not contain handwritten characters; the usable area can be used to indicate blank areas on physical paper.
[0084] Electronic devices can perform optical character recognition (OCR) on the first image to identify the usable areas of the physical paper. Character recognition methods can include binarization, noise filtering, correlation domain analysis, AdaBoost, CNN algorithms, softmax algorithms, etc.
[0085] This application's embodiments utilize the robustness of deep learning algorithms such as object detection and character recognition, without limiting the color or model of the stylus, or imposing special requirements on the specifications and materials of the physical paper. It is simple to use, applicable to a wide range of scenarios, and highly portable.
[0086] 304. Within the usable area, allocate the corresponding entity answer area for the questions to be answered based on the number and type of questions.
[0087] 305. Output the location of the physical answer area on the physical paper.
[0088] 306. Obtain the second image of the physical paper.
[0089] The physical answer area is the area on the physical paper where the user writes their answers. After the user writes their answers in the physical answer area, the electronic device can acquire a second image of the physical paper. The second image includes the physical paper and the user's written answers. Optionally, the electronic device can acquire the second image of the physical paper when it detects a user's voice command, such as "I have finished answering"; or, the electronic device can acquire the second image of the physical paper when it detects a third user operation, such as triggering a virtual button to start recording; or, after outputting the position of the physical answer area on the physical paper, the electronic device can start a countdown function, and acquire the second image of the physical paper after the corresponding answer time has elapsed.
[0090] 307. Based on the position of the physical answer area on the physical paper, determine the corresponding area position of the physical answer area in the second image.
[0091] In some embodiments, the location of the entity answer area in the second image can refer to the position of the entity answer area in the second image, or it can refer to the position of the coverage area that can cover the entity answer area in the second image. The coverage area can be larger than the entity answer area. For example, the coverage area can be 1.25 times, 1.5 times, etc., of the entity answer area, and there is no specific limitation. Having a coverage area larger than the entity answer area avoids the problem that when a user writes their answer in the entity answer area, part of the written answer may extend beyond the entity answer area, causing the written content outside the entity answer area to be unrecognizable by the electronic device, thus improving the accuracy of recognizing the user's written answer.
[0092] 308. Identify the location of the area and obtain the written answer written in the entity answer area.
[0093] The electronic device only identifies the location of a specific area, eliminating the need to recognize the entire second image. This reduces the computational load for character recognition, speeds up the recognition process, and improves the user's learning efficiency. Optionally, the electronic device can perform character recognition on the specific area to obtain the written answer to be placed in the physical answer area.
[0094] This application embodiment determines the physical answer area corresponding to the questions to be answered on the usable area of the physical paper according to the number and type of questions. This is beneficial for reasonably determining the physical answer area corresponding to the questions on the physical paper based on the actual use of the physical paper, thereby improving the paper utilization rate. At the same time, it provides users with reasonable answer prompts and improves the standardization of users' answers on the physical paper.
[0095] Please see Figure 4 , Figure 4This is an example diagram illustrating an application scenario of another question-answering suggestion method disclosed in the embodiments of this application. For example... Figure 4 As shown, the number of questions to be answered is 1, and the question type is fill-in-the-blank. The Arabic numeral 19 on the physical paper is a handwritten character that already exists on the physical paper. Users can determine the physical answer area on the usable area of the physical paper based on the position of the physical answer area output by the electronic device through virtual images, voice broadcasts, or text displays, and write their answers in the physical answer area.
[0096] Please see Figure 5 , Figure 5 This is a flowchart illustrating another question-answering suggestion method disclosed in an embodiment of this application. This method can be applied to any of the aforementioned electronic devices. Figure 5 As shown, the method includes the following steps:
[0097] 501. Display the questions to be answered, as well as the original answer area for those questions.
[0098] The original answer area is different from the virtual answer area. The original answer area can be the actual electronic answer area assigned to each question in the answer software or application of the electronic device. Users can enter their written answers in the original answer area through the electronic device's handwriting keyboard, virtual buttons, or an electronic handwriting tablet connected to the electronic device.
[0099] 502. Identify the question type and number of questions to be answered.
[0100] 503. Determine the corresponding physical answer area on the physical paper for each question based on the number and type of questions.
[0101] 504. Display the virtual paper corresponding to the physical paper.
[0102] The virtual paper can be a digital image output through the display screen of an electronic device. Optionally, the electronic device detects the position and size of the physical paper within the original image using a target detection algorithm, obtains a first image of the physical paper, and then scales the first image proportionally to obtain the virtual paper; alternatively, the electronic device can generate the virtual paper corresponding to the physical paper upon detecting a second user operation, which can be an operation to input parameters for the virtual paper, including the length, width, and display position of the physical paper on the display screen of the electronic device.
[0103] The electronic device can automatically map the virtual paper to a target position on the screen of the electronic device based on the model of the electronic device and the interface settings of the answer software of the electronic device; the target position can be a position on the screen of the electronic device that does not obstruct the questions to be answered or the original answer area.
[0104] 505. Overlay a virtual answer area on the virtual paper to indicate the position of the physical answer area on the physical paper by the position of the virtual answer area on the virtual paper.
[0105] One physical answer area corresponds to one virtual answer area. The position of the virtual answer area on the virtual paper can intuitively and clearly indicate the position of the physical answer area on the physical paper, which helps users to write their answers accurately and in a standardized manner in the physical answer area on the physical paper.
[0106] 506. Recognize handwritten answers written in the entity answer area.
[0107] The electronic device can recognize characters of the written answers written on the entire physical paper, or it can recognize characters of the written answers written only in the physical answer area; there is no specific limitation.
[0108] 507. Display the written answers in the virtual answer area corresponding to the physical answer area.
[0109] Electronic devices can map the recognized written answers to a virtual answer area corresponding to the physical answer area. This allows users to determine whether they have answered correctly in the physical answer area on the physical paper based on the position of their written answers in the virtual answer area, thus improving the standardization of their answers.
[0110] 508. Display the written answer in the original answer area.
[0111] Electronic devices can map recognized handwritten answers to the original answer area, eliminating the need for users to input answers directly into the original answer area using the device's handwriting keyboard, virtual buttons, or a connected electronic writing tablet. This simultaneously provides the experience of paper writing and the advantages of electronic recording and display. The electronic device can also compare the handwritten answers displayed in the original answer area with the standard answers to the questions.
[0112] This application embodiment achieves its purpose through software integration, requiring only operation on electronic devices such as laptops, smartphones, and tablets, without the need for additional hardware devices (such as electronic writing tablets), thus greatly reducing costs.
[0113] This application embodiment determines the physical answer area on the physical paper corresponding to the identified question type and the number of questions included in the question to be answered, and overlays a virtual answer area on the corresponding virtual paper. This allows the user to answer in a standardized manner in the physical answer area corresponding to the physical paper based on the position of the virtual answer area output by the electronic device on the virtual paper, thereby improving the standardization of the answer and reducing the difficulty of recognizing the written content.
[0114] Please see Figure 6 , Figure 6 This is an example diagram illustrating an application scenario of another question-answering suggestion method disclosed in the embodiments of this application. For example... Figure 6 As shown, the Arabic numeral 140 represents the written answer. The electronic device can recognize the written answer written in the physical answer area of the physical paper and display the written answer in the virtual answer area corresponding to the physical answer area, as well as in the original answer area.
[0115] Please see Figure 7 , Figure 7 This is a flowchart illustrating another question-answering suggestion method disclosed in an embodiment of this application. This method can be applied to any of the aforementioned electronic devices. Figure 7 As shown, the method includes the following steps:
[0116] 701. Identify the question type of the questions to be answered, as well as the number of questions included in the questions to be answered.
[0117] 702. Determine the corresponding physical answer area on the physical paper for each question based on the number and type of questions.
[0118] 703. Identify the paper type of a physical paper.
[0119] Electronic devices can identify the type of paper in physical paper using deep learning algorithms, such as convolution algorithms, without being specifically limited to any particular type.
[0120] 704. Output the position of the physical answer area on the physical paper using the output method corresponding to the paper type of the physical paper.
[0121] In some embodiments, the paper type includes: blank paper; when the paper type of the physical paper is blank paper, a virtual paper corresponding to the physical paper is displayed; a virtual answer area corresponding to the physical answer area is superimposed on the virtual paper, so as to indicate the position of the physical answer area on the physical paper by the position of the virtual answer area on the virtual paper.
[0122] It should be noted that blank paper can be paper that does not include reference lines for marking positions, but it can include blank paper that already contains handwritten characters.
[0123] In some embodiments, the paper type includes: non-blank paper, which includes reference lines for marking positions; when the paper type of the physical paper is non-blank paper, a reference line corresponding to the physical answer area is determined; and information about the reference line corresponding to the physical answer area is displayed via voice or text.
[0124] Non-blank paper may include single-line paper and grid paper, but is not limited to these.
[0125] Optionally, when the physical paper is a single-line sheet, the electronic device determines the reference line used for marking the position as the line line of each row in the single-line sheet, and determines the target line line corresponding to the physical answer area. The electronic device can announce or display the target line line information corresponding to the physical answer area through voice or text. The target line line information includes the number of rows corresponding to the target line line and the number of physical answer areas corresponding to the target line line. For example, the electronic device can prompt the user through voice or text to write the answer on which line of the single-line sheet, and can also prompt the user to write how many answers on which line of the single-line sheet. Thus, the user can arrange the layout of the written answers reasonably on the single-line sheet according to the answer prompts, improving the standardization of the answers.
[0126] Optionally, when the physical paper is grid paper, the electronic device determines that the reference line used to mark the position is each cell in the grid paper, and determines the target cell corresponding to the physical answer area. The electronic device can provide voice prompts or text displays the target cell information corresponding to the physical answer area. The target cell information includes the row and column numbers corresponding to the target cell. For example, the electronic device can provide voice prompts or text displays to prompt the user in which cell of the grid paper to write the answer, improving the standardization of the answer.
[0127] In some embodiments, when the physical paper is non-blank paper, the electronic device can also display a virtual paper corresponding to the physical paper; a virtual answer area corresponding to the physical answer area is superimposed on the virtual paper, so as to indicate the position of the physical answer area on the physical paper by the position of the virtual answer area on the virtual paper.
[0128] In this embodiment, when the physical paper is blank, the electronic device can preferentially display virtual paper and virtual answer area to provide answer prompts to the user, which helps to improve the standardization of the user's answers on blank paper. When the physical paper is non-blank, since non-blank paper includes reference lines for marking positions, the electronic device can provide answer prompts to the user through convenient methods such as voice broadcast or text display, which improves the efficiency and flexibility of answer prompts.
