Abstract
Description
Technical Field
[0001] The present invention relates to the field of electronic writing technology, and more specifically, to a writing method that supports draft paper when writing on an electronic ink screen. Background Art
[0002] Electronic ink screen is a screen that uses electronic ink. Electronic ink screen is also called electronic paper display technology. Electronic ink is a new method and technology that innovates information display. Like most traditional inks, electronic ink and the circuits that change its color can be printed on many surfaces, from curved plastic, polyester film, paper to cloth. The difference from traditional paper is that electronic ink changes color when powered on, and can display changing images, like the display of a calculator or mobile phone.
[0003] With the continuous development of electronic ink screen technology, its application is becoming more and more extensive. In the field of education, it can be used for students to do paperless exercises. When using electronic ink screens to do exercises, similar to solving math problems, students need to use draft paper for calculations. At this time, students need to use paper draft paper. Students may not be able to find paper draft paper or their answering ideas may be interrupted in the process of looking for paper draft paper, which is not conducive to answering questions. And the non-reusability of paper draft paper will also increase paper consumption.
[0004] Therefore, in view of the above situation, it is necessary to establish a draft paper solution that is easy to use and reduces paper consumption. Summary of the invention
[0005] 1. Technical issues to be solved
[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a writing method that supports draft paper when writing on an electronic ink screen. When answering questions on the electronic ink screen, a new area can be created as a draft paper. The question currently being answered by the student is used as the background of this area. The student can use this area to answer the question and calculate, and mark the important information of the current question. When the calculation is wrong, the student can use the erase handwriting function to erase the wrong part. When an area cannot be sufficient for the calculation content, another calculation area can be added. The last calculation content will be retained, and it is possible to switch between the current calculation area and the last calculation area. The above functions can all be achieved through the electronic ink screen or an external smart writing pen, which is convenient for students to perform quick operations and allows students to quickly and conveniently switch to draft calculation when answering questions. At the same time, it also reduces the consumption of paper and achieves the purpose of environmental protection.
[0007] 2. Technical solution
[0008] To solve the above problems, the present invention adopts the following technical solutions.
[0009] A method for writing on an electronic ink screen while supporting a draft paper comprises the following steps:
[0010] Step 1: When the user is in the test-taking interface on the electronic ink screen, use the smart writing pen to click "Draft Paper". The system will take a screenshot of the visible area of the test-taking interface and save it locally, and jump to the draft paper interface at the same time;
[0011] Step 2: Create a new draft paper interface. This interface uses the saved screenshot of the visible area of the answering interface as the background. Users can mark and calculate the questions.
[0012] Step 3: The draft paper can prompt you to save your calculation content. When you exit the draft paper interface and re-enter the draft paper interface, the interface will automatically load the user's last calculation notes, and the user can continue the last calculation content.
[0013] Step 4: When calculating, if the user makes a mistake, he can use the erase function to erase the wrong handwriting. If the current page cannot meet the calculation requirements, the next page of blank draft calculation area can be added;
[0014] Step 5: When the user finishes the draft calculation, click the return button. The system saves the calculation content, converts it into image format and saves it in the hardware device memory, and returns to the answering interface to answer the questions.
[0015] Furthermore, the screenshot of the visible area of the question-solving interface in step 1 maintains a difference in color from the writing on the draft paper interface, which can avoid the calculation content and the question stem content being similar in color and thus difficult to distinguish.
[0016] Furthermore, in step 3, the current calculation content will be automatically backed up locally while writing, and the automatic backup interval is 20-30s, and the previous backup content will be automatically overwritten. After the user accidentally erases the calculation content, the automatically backed-up calculation content can be called for restoration.
[0017] Furthermore, in step 4, the previous operation can be undone and the undone operation can be restored.
[0018] Furthermore, in step 4, when the draft paper exceeds two pages, the user can freely turn the entire page of the draft paper or part of the draft paper.
[0019] Furthermore, in step 5, you can choose to upload the saved calculation content to the cloud and set access permissions, which can not only perform cloud backup in time to prevent local file loss, but also allow remote access and download through other devices for learning.
[0020] Furthermore, the smart writing pen includes a pen body and multiple function switches, and the built-in communication module of the smart writing pen is communicatively connected to the electronic ink screen, a plurality of switch slots matching the function switches are opened on the side wall of the pen body, and the function switches are slidably connected to the switch slots, a static contact is electrically connected to the bottom wall of the switch slot, and the end of the function switch close to the static contact is electrically connected to a moving contact, a pair of phase change spacer balls are embedded between the moving contact and the static contact, and a pair of phase change spacer balls are fixedly connected to a linkage push rod at one end away from each other, and the switch slot A pair of migration grooves matching the linkage push rod are opened on the side wall, and the linkage push rod is inserted in the migration groove. Under normal conditions, the phase change spacer ball can undergo elastic deformation. Even if the function switch is accidentally touched and squeezed, it will be blocked between the moving contact and the static contact due to the deformation of the phase change spacer ball, making it impossible for the moving contact and the static contact to contact normally and transmit signals. Only after the phase change spacer ball is energized and hardened, it will push the linkage push rod to separate from each other when squeezed by the moving contact. At this time, the moving contact and the static contact can contact normally to transmit signals, and then send the specified function instructions.
[0021] Furthermore, the phase change spacer ball includes an inner diaphragm layer, an outer covering layer and a magnetic attraction point. The outer covering layer is coated on the outer surface of the inner diaphragm layer. The magnetic attraction point is fixedly connected to the inner end of the inner diaphragm layer and is located on the side of the inner diaphragm layer away from the linkage push rod. The inner side of the inner diaphragm layer is filled with electrorheological fluid. The outer covering layer is coated on the outer surface of the inner diaphragm layer to play a certain protective role, which can effectively prevent the inner diaphragm layer from rupture. At the same time, after the electrorheological fluid in the inner diaphragm layer is energized and hardened, it is easy to separate under the extrusion of the moving contact due to the smoothness of the outer covering layer. The magnetic attraction point can make a pair of phase change spacer balls attract each other. After being squeezed by the moving contact in the non-hardened state, it can ensure isolation between the moving contact and the static contact, thereby improving the effect of preventing accidental touch.
[0022] Furthermore, the inner diaphragm layer is made of elastic insulating material, the outer covering layer includes a plurality of outer covering scales made of hard and smooth material, and the outer covering scales are densely distributed, and the magnetic attraction points are made of magnetic material.
[0023] Furthermore, the side wall of the pen body is inlaid with a plurality of pairs of transparent prompt ports symmetrically distributed about the function switch, and the transparent prompt ports are connected to the migration groove. The transparent prompt ports are filled with colored magnetic particles. When the phase change spacer ball separates and pushes the linkage push rod, the colored magnetic particles adsorbed by the phase change spacer ball are squeezed back into the transparent prompt port for color display prompts, so that students can observe more intuitively, which makes it difficult to press the wrong function switch and cause misoperation, and can also save electricity and improve battery life.
[0024] 3. Beneficial effects
[0025] Compared with the prior art, the advantages of the present invention are:
[0026] (1) This solution can create a new area as a draft paper when answering questions on the electronic ink screen. The question that the student is currently answering serves as the background of this area. The student can use this area to answer the question and mark the important information of the current question. When the calculation is wrong, the student can use the erase handwriting function to erase the wrong part. When an area is insufficient for the calculation content, another calculation area can be added. The last calculation content will be retained, and the student can switch between the current calculation area and the last calculation area. The above functions can be realized through the electronic ink screen or an external smart writing pen, which is convenient for students to operate quickly and conveniently, allowing students to switch to the draft calculation when answering questions. At the same time, it also reduces the consumption of paper and achieves the purpose of environmental protection.
[0027] (2) The visible area of the test screen should be different in color from the writing area on the draft paper. This can prevent the calculation content and the question stem from being too similar in color to be easily distinguished.
[0028] (3) When writing, the current calculation content will be automatically backed up to the local computer, and the automatic backup interval is 20-30 seconds, and the previous backup content will be automatically overwritten. If the user accidentally erases the calculation content, the automatically backed-up calculation content can be called for restoration.
[0029] (4) You can choose to upload the saved calculation content to the cloud and set access permissions. This not only allows for timely cloud backup to prevent local file loss, but also allows for remote access and download through other devices for learning.
[0030] (5) The smart writing pen includes a pen body and a plurality of function switches, and a communication module is built into the smart writing pen to communicate with the electronic ink screen. A plurality of switch slots matching the function switches are provided on the side wall of the pen body, and the function switches are slidably connected to the switch slots. A static contact is electrically connected to the bottom wall of the switch slot, and a moving contact is electrically connected to one end of the function switch close to the static contact. A pair of phase change spacer balls are embedded between the moving contact and the static contact, and a linkage push rod is fixedly connected to the ends of the pair of phase change spacer balls away from each other. A pair of A migration groove matches the linkage push rod, and the linkage push rod is inserted in the migration groove. Under normal conditions, the phase-change spacer ball can undergo elastic deformation. Even if the function switch is accidentally touched and squeezed, it will be blocked between the moving contact and the static contact due to the deformation of the phase-change spacer ball, making it impossible for the moving contact and the static contact to contact normally and transmit signals. Only after the phase-change spacer ball is energized and hardened, it will push the linkage push rod to separate from each other when squeezed by the moving contact. At this time, the moving contact and the static contact can contact normally to transmit signals, and then send the specified function instructions.
[0031] (6) The phase-change spacer ball includes an inner diaphragm layer, an outer covering layer and a magnetic attraction point. The outer covering layer is coated on the outer surface of the inner diaphragm layer. The magnetic attraction point is fixedly connected to the inner end of the inner diaphragm layer and is located on the side of the inner diaphragm layer away from the linkage push rod. The inner side of the inner diaphragm layer is filled with electrorheological fluid. The outer covering layer is coated on the outer surface of the inner diaphragm layer to play a certain protective role, which can effectively prevent the inner diaphragm layer from rupture. At the same time, after the electrorheological fluid in the inner diaphragm layer is energized and hardened, it is easy to separate under the extrusion of the moving contact due to the smoothness of the outer covering layer. The magnetic attraction point can make a pair of phase-change spacer balls attract each other. After being squeezed by the moving contact in the non-hardened state, it can ensure isolation between the moving contact and the static contact, thereby improving the effect of preventing accidental touch.
[0032] (7) The side wall of the pen body is inlaid with multiple pairs of transparent prompt ports symmetrically distributed about the function switch, and the transparent prompt ports are connected to the migration groove. The transparent prompt ports are filled with colored magnetic particles. When the phase change spacer ball separates and pushes the linkage push rod, the colored magnetic particles adsorbed by the phase change spacer ball will be squeezed back into the transparent prompt port for color display prompts, so that students can observe more intuitively, which makes it difficult to press the wrong function switch and cause misoperation, and can also save power and increase battery life.

[0046] Embodiment 1:
[0047] See also Figure 1 , a writing method supporting draft paper when writing on an electronic ink screen, comprising the following steps:
[0048] Step 1: When the user is in the test-taking interface on the electronic ink screen, use the smart writing pen to click "Draft Paper". The system will take a screenshot of the visible area of the test-taking interface and save it locally, and jump to the draft paper interface at the same time;
[0049] Step 2: Create a new draft paper interface. This interface uses the saved screenshot of the visible area of the answering interface as the background. Users can mark and calculate the questions.
[0050] Step 3: The draft paper can prompt you to save your calculation content. When you exit the draft paper interface and re-enter the draft paper interface, the interface will automatically load the user's last calculation notes, and the user can continue the last calculation content.
[0051] Step 4: When calculating, if the user makes a mistake, he can use the erase function to erase the wrong handwriting. If the current page cannot meet the calculation requirements, the next page of blank draft calculation area can be added;
[0052] Step 5: When the user finishes the draft calculation, click the return button. The system saves the calculation content, converts it into image format and saves it in the hardware device memory, and returns to the answering interface to answer the questions.
[0053] The visible area screenshot of the test-taking interface in step 1 should be different from the writing color of the draft paper interface to avoid the calculation content and the question content being too similar in color to be easily distinguished.
[0054] In step 3, the current calculation content will be automatically backed up locally while writing, and the automatic backup interval is 20-30s, and it will automatically overwrite the last backup content. If the user accidentally erases the calculation content, the automatically backed-up calculation content can be called for restoration.
[0055] In step 4, the previous operation can also be undone and the undone operation can be restored.
[0056] In step 4, when the draft paper exceeds two pages, the user can freely turn the entire page of the draft paper or part of the draft paper.
[0057] In step 5, you can choose to upload the saved calculation content to the cloud and set access permissions. This not only allows for timely cloud backup to prevent local file loss, but also allows remote access and download through other devices for learning.
[0058] See also Figure 2-5The smart writing pen includes a pen body 1 and multiple function switches 2, and the built-in communication module of the smart writing pen is connected to the electronic ink screen for communication, which can be connected by cable connection or communication modules such as Bluetooth to send corresponding instructions. Multiple switch slots matching the function switches 2 are opened on the side wall of the pen body 1, and the function switches 2 are slidably connected to the switch slots. A static contact 5 is electrically connected to the bottom wall of the switch slot. The end of the function switch 2 close to the static contact 5 is electrically connected to a moving contact 4. A pair of phase change spacer balls 6 are embedded between the moving contact 4 and the static contact 5. The ends of the pair of phase change spacer balls 6 far away from each other are fixedly connected with a linkage push Rod 7, a pair of migration grooves matching the linkage push rod 7 are opened on the side wall of the switch groove, and the linkage push rod 7 is inserted in the migration groove. Under normal conditions, the phase-change spacer ball 6 can be elastically deformed. Even if the function switch 2 is accidentally touched and squeezed, it is blocked between the moving contact 4 and the static contact 5 under the deformation of the phase-change spacer ball 6, so that the moving contact 4 and the static contact 5 cannot contact normally to transmit signals. Only after the phase-change spacer ball 6 is energized and hardened, it will push the linkage push rod 7 to separate from each other when squeezed by the moving contact 4. At this time, the moving contact 4 and the static contact 5 can contact normally to transmit signals, and then send the specified function instructions.
[0059] See also Figure 6 The phase-change spacer ball 6 includes an inner diaphragm layer 61, an outer covering layer 62 and a magnetic attraction point 63. The outer covering layer 62 is coated on the outer surface of the inner diaphragm layer 61. The magnetic attraction point 63 is fixedly connected to the inner end of the inner diaphragm layer 61 and is located on the side of the inner diaphragm layer 61 away from the linkage push rod 7. The inner side of the inner diaphragm layer 61 is filled with electrorheological fluid. The outer covering layer 62 is coated on the outer surface of the inner diaphragm layer 61 to play a certain protective role, which can effectively prevent the inner diaphragm layer 61 from rupture. At the same time, after the electrorheological fluid in the inner diaphragm layer 61 is energized and hardened, it is easy to separate under the extrusion of the moving contact 4 under the smooth effect of the outer covering layer 62. The magnetic attraction point 63 can make a pair of phase-change spacer balls 6 attract each other. After being squeezed by the moving contact 4 in the non-hardened state, it can ensure isolation between the moving contact 4 and the static contact 5, thereby improving the effect of preventing accidental touch.
[0060] The inner diaphragm layer 61 is made of elastic insulating material, the outer covering layer 62 includes a plurality of outer covering scales made of hard and smooth material, and the outer covering scales are densely distributed, and the magnetic attraction points 63 are made of magnetic material.
[0061] See also Figure 7A plurality of pairs of transparent prompt ports 3 symmetrically distributed about the function switch 2 are inlaid and connected on the side wall of the pen body 1, and the transparent prompt ports 3 are connected to the migration groove. The transparent prompt ports 3 are filled with colored magnetic particles 8. When the phase-change spacer ball 6 separates and pushes the linkage push rod 7, the colored magnetic particles 8 adsorbed by the phase-change spacer ball 6 are squeezed back into the transparent prompt port 3 for color display prompts, so that students can observe more intuitively, which makes it difficult to press the wrong function switch 2 and cause misoperation, and can also save electricity and improve battery life.
[0062] A fingerprint recognition module can be set on the function switch 2. The circuit is connected only when the user presses it with his thumb, so that the electrorheological fluid in the phase change spacer ball 6 is energized and hardened, and then separated by squeezing the moving contact 4 and then contacting the static contact 5 to transmit the signal, thereby realizing the issuance of the function instruction.
[0063] The present invention can create a new area as a draft paper when answering questions on the electronic ink screen, and the question currently being answered by the student is used as the background of this area. The student can use this area to perform answer calculations and mark important information of the current question. When a calculation error occurs, the student can use the erase handwriting function to erase the wrong part. When an area is insufficient for calculation content, another calculation area can be added, and the last calculation content will be retained. The current calculation area and the last calculation area can be switched. The above functions can all be realized through the electronic ink screen or an external smart writing pen, which is convenient for students to perform quick operations and allows students to quickly and conveniently switch to draft calculations when answering questions. At the same time, it also reduces the consumption of paper and achieves the purpose of environmental protection.
[0064] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
