The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the application discloses a display method and device of three-dimensional characters, electronic equipment and a storage medium, which are beneficial to improving the enthusiasm and interest of students in writing learning contents including words. The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for displaying three-dimensional characters according to a first embodiment of the present disclosure. The three-dimensional character display method described in fig. 1 is suitable for various electronic devices such as education devices (e.g., family education devices, classroom electronic devices), computers (e.g., student tablets, personal PCs), mobile phones, smart home devices (e.g., smart televisions, smart speakers, and smart robots), and the like, and the embodiment of the present application is not limited thereto. In the display method of the three-dimensional character described in fig. 1, the display method of the three-dimensional character is described with an electronic apparatus as an execution subject. As shown in fig. 1, the method for displaying three-dimensional characters may include the steps of:

101. the electronic device obtains the selected learning content.

For example, the electronic device may capture the learning content selected by the user (e.g., clicked by the user) in the learning module through a camera device (e.g., a camera).

For example, the learning module may be a certain learning page (e.g., a paper learning page or an electronic learning page) corresponding to the user, or may be a certain learning section included in a certain learning page corresponding to the user.

In some examples, the electronic device may locate the learning module selected by the user's finger, stylus, or voice and treat the learning module selected by the user's finger, stylus, or voice as the learning module corresponding to the user. For example, the electronic device may use a camera (e.g., a camera) to capture a learning module selected by a finger or a writing pen of a user as a learning module corresponding to the user; alternatively, the electronic device may use a sound pickup device (e.g., a microphone) to pick up a learning module selected by the voice uttered by the user as the learning module corresponding to the user. In some embodiments, the camera device (e.g., a camera) may be disposed on a ring worn by a finger of a user, and when the ring detects that the finger of the user worn by the ring is straightened, the ring may start the camera device (e.g., the camera) to shoot a learning module selected by the finger of the user, and the ring transmits the shot learning module selected by the finger of the user to the electronic device, so that the electronic device may determine the learning module corresponding to the user. By the implementation of the implementation mode, power consumption caused by the fact that the electronic equipment shoots the learning module selected by the finger of the user can be reduced, and therefore battery endurance of the electronic equipment can be improved.

In other examples, the electronic device may obtain the learning module selected by the other external device for the user, and use the learning module selected by the other external device for the user as the learning module corresponding to the user. For example, the electronic device may establish a communication connection with a wrist wearable device worn by a supervisor (such as a classroom teacher or a parent) of a user in advance, the supervisor holds a certain finger of a palm where a wrist wearing the wrist wearable device is located against a root of an ear to make the ear form a closed sound cavity, and the supervisor may send out a voice signal with a volume lower than a certain threshold value for selecting a learning module for the user; the voice signal is transmitted into the wrist type wearing equipment as a vibration signal through a bone medium of a palm, and the voice signal is transmitted to the electronic equipment through the wrist type wearing equipment. By implementing the implementation mode, a supervisor (such as a classroom teacher or a parent) of the user can flexibly select the learning module for the user, and sound interference to surrounding people is avoided in the process of selecting the learning module for the user.

In some embodiments, when the external device may be a wrist-worn device worn by a classroom teacher, the wrist-worn device may establish a communication connection with electronic devices used by multiple users (i.e., students) in a classroom simultaneously, and accordingly, the voice signal sent by the supervisor and used for selecting a learning module for the user, the voice signal having a volume below a certain threshold, may include an identifier (e.g., a chapter number) of the selected learning module and an identifier (e.g., a name and/or a seat number) of the user; further, the wrist-worn device may transmit the voice signal to the electronic device used by the user according to an identification (such as a name and/or a seat number) of the user, so that the electronic device used by the user may determine the learning module corresponding to the user according to an identification (such as a chapter number) of the selected learning module included in the voice signal. By implementing the implementation mode, a classroom teacher can respectively select different learning modules for a plurality of users in a classroom according to different respective learning progresses of the users in the classroom (such as a training classroom), so that the flexibility and convenience of respectively selecting different learning modules for the users in the classroom can be improved.

For example, the learning content selected by the user (e.g., clicked by the user) may include foreign language words (e.g., english words), musical notation strings (e.g., musical notation strings represented by numerals 1-7), chinese characters, and so on, and the embodiments of the present application are not limited thereto.

102. The electronic device recognizes each two-dimensional character included in the learning content.

Illustratively, if the learning content is the English word "ruler", the electronic device identifies five two-dimensional characters, r, u, l, e, and r, contained in the English word "ruler".

103. And the electronic equipment acquires the three-dimensional character corresponding to each two-dimensional character in the two-dimensional characters.

In some examples, the electronic device may convert each of the respective two-dimensional characters into a three-dimensional character based on a 3D synthesis technique of 3D structure reconstruction, so that a three-dimensional character corresponding to each of the respective two-dimensional characters may be obtained.

104. And after detecting that any target two-dimensional character in the two-dimensional characters is written, the electronic equipment displays a three-dimensional character corresponding to the target two-dimensional character.

In some examples, after detecting that any one of the target two-dimensional characters is written, the electronic device may display a three-dimensional character corresponding to the target two-dimensional character on a display screen of the electronic device. For example, after detecting that any target two-dimensional character r in the english word "ruler" is written, the electronic device may display a three-dimensional character corresponding to the target two-dimensional character r on a display screen of the electronic device. After the electronic device detects that the five target two-dimensional characters of r, u, l, e and r in the english word "ruler" are all written, three-dimensional characters corresponding to the five target two-dimensional characters of r, u, l, e and r can be displayed on a display screen of the electronic device, so that a user can see the three-dimensional english word "ruler" formed by the three-dimensional characters corresponding to the five target two-dimensional characters of r, u, l, e and r on the display screen of the electronic device.

In other examples, after detecting that any one of the target two-dimensional characters is written, the electronic device may first recognize a writing position where the target two-dimensional character is written, and display a three-dimensional character corresponding to the target two-dimensional character at the writing position in an augmented reality manner. For example, after detecting that any target two-dimensional character r in the english word "ruler" is written, the electronic device may recognize a writing position where the target two-dimensional character r is written, and if the writing position where the target two-dimensional character r is written is located on a certain paper page, the electronic device may display a three-dimensional character corresponding to the target two-dimensional character r on the writing position on the paper page in an augmented reality manner. When the three-dimensional characters corresponding to the five target two-dimensional characters of r, u, l, e and r in the english word "ruler" are displayed on the corresponding writing positions of the paper page in an augmented reality manner, the user can see the three-dimensional english word "ruler" consisting of the three-dimensional characters corresponding to the five target two-dimensional characters of r, u, l, e and r on the paper page.

Therefore, the implementation of the three-dimensional character display method described in fig. 1 can improve the man-machine interaction of the student when writing words, thereby being beneficial to improving the enthusiasm and interest of the student when writing learning contents including words.

In addition, by implementing the method for displaying three-dimensional characters described in fig. 1, power consumption caused by the fact that the electronic device shoots the learning module selected by the user's finger can be reduced, and thus battery endurance of the electronic device can be improved.

In addition, by implementing the method for displaying three-dimensional characters as described in fig. 1, a supervisor (such as a teacher or a parent) of a user can flexibly select a learning module for the user, and does not cause sound interference to surrounding people in the process of selecting the learning module for the user.

In addition, by implementing the three-dimensional character display method described in fig. 1, different learning modules can be respectively selected for a plurality of users in a classroom (such as a training classroom) according to respective different learning progresses of the plurality of users in the classroom, so that flexibility and convenience in selecting different learning modules for the plurality of users in the classroom can be improved.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for displaying three-dimensional characters according to a second embodiment of the present disclosure. In the display method of the three-dimensional character described in fig. 2, the display method of the three-dimensional character is described with an electronic apparatus as an execution subject. As shown in fig. 2, the method for displaying three-dimensional characters may include the steps of:

201. the electronic device obtains the selected learning content.

The implementation manner of step 3201 may be the same as that of step 101, and is not described herein again in this embodiment of the application.

202. The electronic device recognizes each two-dimensional character included in the learning content.

203. And the electronic equipment acquires the three-dimensional character corresponding to each two-dimensional character in the two-dimensional characters.

204. The electronic device recognizes a writing position where any one of the target two-dimensional characters is written after detecting that the target two-dimensional character is written.

For example, the written position where the target two-dimensional character is written may be a written position on a display screen of the electronic device; alternatively, the writing position where the target two-dimensional character is written may be a written position on a paper page.

205. And the electronic equipment displays the three-dimensional character corresponding to the target two-dimensional character at the writing position in an augmented reality mode.

206. The electronic device judges whether the three-dimensional characters corresponding to the two-dimensional characters are completely displayed in an augmented reality mode, if so, step 207 is executed; if not, return to step 204.

207. The electronic equipment detects whether the learning content is associated with an object to be unlocked, and if the learning content is associated with the object to be unlocked, the steps 208-210 are executed; if the learning content is not associated with the object to be unlocked, the process is ended.

For example, the object to be unlocked may be an APP to be unlocked, an electronic screen to be unlocked, an intelligent door lock to be unlocked, and the like, which is not limited in the embodiment of the present application.

208. The electronic equipment acquires the appointed display gesture of the three-dimensional character corresponding to each two-dimensional character in the two-dimensional characters configured on the object to be unlocked.

For example, the designated display pose of the three-dimensional character may include a designated display direction of the three-dimensional character, and a designated display inclination in the designated display direction.

209. And the electronic equipment determines the instant display posture when the three-dimensional character corresponding to each two-dimensional character in the two-dimensional characters is displayed in an augmented reality mode.

For example, the instantaneous display posture of the three-dimensional character when displayed in the augmented reality manner may include an instantaneous display direction of the three-dimensional character when displayed in the augmented reality manner, and an instantaneous display inclination in the instantaneous display direction.

210. The electronic equipment checks whether the instant display posture of the three-dimensional character corresponding to any two-dimensional character when the three-dimensional character is displayed in an augmented reality mode is different from the appointed display posture of the three-dimensional character corresponding to the two-dimensional character configured on the object to be unlocked, and if the instant display posture is different from the appointed display posture, the steps 211 to 212 are executed; if not, go to step 213.

For example, if it is verified that the instant display direction of the three-dimensional character corresponding to any one two-dimensional character displayed in the augmented reality manner is different from the specified display direction of the three-dimensional character corresponding to the two-dimensional character configured for the object to be unlocked, the electronic device executes step 211; and/or if it is verified that the instant display gradient of the three-dimensional character corresponding to any one two-dimensional character displayed in the augmented reality manner is different from the specified display gradient of the three-dimensional character corresponding to the two-dimensional character configured for the object to be unlocked, the electronic device executes step 211.

Illustratively, if it is verified that the instant display direction of the three-dimensional character corresponding to any two-dimensional character does not exist in the electronic device when the three-dimensional character corresponding to the two-dimensional character is displayed in an augmented reality manner is different from the specified display direction of the three-dimensional character corresponding to the two-dimensional character configured for the object to be unlocked; and, the electronic device verifies that the instant display gradient when the three-dimensional character corresponding to any one of the two-dimensional characters is not displayed in the augmented reality manner is different from the specified display gradient of the three-dimensional character corresponding to the two-dimensional character configured for the object to be unlocked, then step 213 is executed.

211. If the electronic equipment verifies that the instant display posture when the three-dimensional character corresponding to the at least one two-dimensional character is displayed in the augmented reality mode is different from the appointed display posture of the three-dimensional character corresponding to the two-dimensional character configured on the object to be unlocked, the electronic equipment prompts that the instant display posture when the three-dimensional character corresponding to the at least one two-dimensional character is displayed in the augmented reality mode is controlled in a gesture mode to be adjusted.

Illustratively, the electronic device may prompt, in a voice manner, to control, in a gesture manner, an instant display posture of the three-dimensional character corresponding to the at least one two-dimensional character when the three-dimensional character is displayed in the augmented reality manner to be adjusted; accordingly, the user can control, by means of a gesture, an instant display posture of the three-dimensional character corresponding to the at least one two-dimensional character when the three-dimensional character is displayed in an augmented reality manner to be adjusted (e.g., instant display direction adjustment and/or instant display inclination adjustment) under the prompt.

212. The electronic equipment detects whether the instant display posture of the three-dimensional character corresponding to the at least one two-dimensional character is controlled in a gesture mode to be adjusted when the three-dimensional character is displayed in the augmented reality mode, if yes, 210 is executed; if not, the flow is ended.

213. And the electronic equipment unlocks the object to be unlocked.

Therefore, the implementation of the three-dimensional character display method described in fig. 2 can improve the man-machine interaction of the student when writing words, thereby being beneficial to improving the enthusiasm and interest of the student when writing learning contents including words.

In addition, the implementation of the method for displaying three-dimensional characters described in fig. 2 can reduce power consumption caused by the fact that the electronic device shoots the learning module selected by the user's finger, so that the battery endurance of the electronic device can be improved.

In addition, by implementing the method for displaying three-dimensional characters as described in fig. 2, a supervisor (such as a teacher or a parent) of a user can flexibly select a learning module for the user, and does not cause sound interference to surrounding people in the process of selecting the learning module for the user.

In addition, by implementing the three-dimensional character display method described in fig. 2, different learning modules can be respectively selected for a plurality of users in a classroom (such as a training classroom) according to respective different learning progresses of the plurality of users in the classroom, so that flexibility and convenience in selecting different learning modules for the plurality of users in the classroom can be improved.

In addition, with the implementation of the three-dimensional character display method described in fig. 2, a user can display three-dimensional characters corresponding to two-dimensional characters by writing the two-dimensional characters of learning content (such as english words), and can unlock the object to be unlocked associated with the learning content by accurately adjusting the instant display posture of the three-dimensional characters corresponding to the two-dimensional characters when the three-dimensional characters corresponding to the two-dimensional characters are displayed in an augmented reality manner, so that the instant display posture of the three-dimensional characters corresponding to the non-adjusted two-dimensional characters when the three-dimensional characters are displayed in the augmented reality manner is the same as the specified display posture of the three-dimensional characters corresponding to the two-dimensional characters configured for the object to be unlocked, thereby improving the security when unlocking the object to be unlocked associated with the learning content while improving the enthusiasm and interest of the student when writing the learning content including words, and improving the enthusiasm and interest of the student when writing the learning content including words and the safety of (1) is fused.

If the electronic equipment verifies that the instant display posture when the three-dimensional character corresponding to the at least one two-dimensional character is displayed in the augmented reality mode is different from the appointed display posture of the three-dimensional character corresponding to the two-dimensional character configured on the object to be unlocked, the electronic equipment prompts that the instant display posture when the three-dimensional character corresponding to the at least one two-dimensional character is displayed in the augmented reality mode is controlled in a gesture mode to be adjusted.

312. The electronic equipment detects whether the instant display posture of the three-dimensional character corresponding to the at least one two-dimensional character is controlled in a gesture mode to be adjusted when the three-dimensional character is displayed in the augmented reality mode, if yes, 310 is executed; if not, the flow is ended.

313. The electronic equipment outputs a spoken language evaluation task which requires reading the learning content in a spoken language manner.

For example, in step 310, if it is verified that the instant display posture when the three-dimensional character corresponding to any one two-dimensional character is not displayed in the augmented reality manner is different from the specified display posture of the three-dimensional character corresponding to the two-dimensional character configured for the object to be unlocked, the electronic device may first obtain the learning target corresponding to the learning content, and find out the target skill mapped to the learning target corresponding to the learning content from the mapping relationship between the learning target and the skill, and if the learning target corresponding to the learning content is "reading aloud" and the target skill mapped to the learning target "reading aloud" corresponding to the learning content is the spoken language assessment skill, the electronic device performs steps 313 to 316. For example, the electronic device may find out that the learning objective corresponding to the learning content is "read aloud" from a preset mapping relationship between the chapter number of the learning content and the learning objective according to the identifier (such as the chapter number) of the learning content.

314. The electronic device collects speakable readings when the learning content is spoken.

315. The electronic equipment compares the reading pronunciation with the standard pronunciation of the learning content, so as to obtain the skill level of the spoken language assessment.

For example, when the electronic device compares the reading pronunciation with the standard pronunciation of the learning content, if the user is found not to read the learning content, the electronic device may obtain that the spoken language assessment skill of the user is "poor"; if the user reads the learning content but the reading of the learning content is not smooth compared with the standard pronunciation of the learning content, the electronic equipment can obtain that the spoken language assessment skill of the user is of a middle level; if the user is found to read the learning content and the learning content is read by the user as normal as the standard pronunciation of the learning content, and the user is read by the user as emotional as the standard pronunciation of the learning content, the electronic device can obtain that the spoken language assessment skill of the user is "excellent level".

In some embodiments, after obtaining the spoken language evaluation skill of the user, the electronic device may further perform the following steps:

the electronic equipment outputs the spoken language evaluation skill of the user to the user in a text and/or voice mode.

Further, the electronic device may detect whether the instant battery power of the electronic device is higher than a first specified power value, and if so, the electronic device may transmit the spoken language assessment skill of the user to a supervisor of the user (e.g., a classroom teacher or a parent). Wherein the first specified electric quantity value may be obtained by:

the electronic equipment determines an electric quantity value increment corresponding to the total times according to the total times of the user executing the spoken language evaluation task in a specified historical period (such as the previous week), subtracts a preset electric quantity value of the electronic equipment from the electric quantity value increment, and takes a subtraction result as a first specified electric quantity value; wherein, the total number of times of executing the oral evaluation task in the appointed historical period (such as the previous week) by the user is in direct proportion to the increment of the electric quantity value corresponding to the total number of times. Therefore, when the user executes more spoken language evaluation tasks in a specified historical period (such as the previous week), the probability that the electronic equipment judges that the instant battery electricity is higher than the first specified electricity value can be remarkably improved, and the probability that the electronic equipment transmits the spoken language evaluation skills of the user to a supervisor (such as a classroom teacher or a parent) of the user can be further improved, so that the supervisor (such as the classroom teacher or the parent) of the user can learn the spoken language evaluation skills of the user with a high probability.

316. The electronic equipment judges whether the spoken language evaluation skill level is higher than a specified level, and if so, the execution is carried out 317; otherwise, the flow is ended.

317. And the electronic equipment unlocks the object to be unlocked.

In some application scenarios, the electronic device may be located in a certain indoor environment, and the to-be-unlocked smart door lock set in the indoor environment may be used as the to-be-unlocked object. In this application scenario, the method for the electronic device to unlock the object to be unlocked in step 317 may be as follows:

the electronic equipment determines current spatial position information of a user using the electronic equipment based on an indoor image shot by an internal camera of the intelligent door lock to be unlocked;

the electronic device can check whether the current spatial position information of the user using the electronic device is matched with the three-dimensional position information of the monitored object which is specially configured by a supervisor (such as a parent) of the user (belonging to the monitored object) relative to the internal camera of the intelligent door lock to be unlocked, and if the current spatial position information is matched with the three-dimensional position information, the intelligent door lock to be unlocked is controlled to be unlocked; wherein, when the user is located in the three-dimensional position information of the monitored object (belonging to the monitored object) specially configured for the user by the user's supervisor (such as a parent) relative to the internal camera of the intelligent door lock to be unlocked, the user can be directly observed by the user's supervisor in the indoor environment. Therefore, the user of the electronic equipment can be required to allow the electronic equipment to control the intelligent door lock to be unlocked to unlock only at a certain spatial position which is specially configured by the supervisor and visible to the supervisor, so that the supervisor can intuitively know which monitored object unlocks the intelligent door lock to be unlocked, the visibility of the user of the electronic equipment when the intelligent door lock to be unlocked is unlocked can be improved, and accidents (such as children being turned) caused by the fact that the user of the electronic equipment secretly unlocks the intelligent door lock to be unlocked under the condition that the supervisor is not aware of are prevented.

In addition, the display method of the three-dimensional character depicted in fig. 3 has the following beneficial effects:

can play the purpose of urging indoor children to carry out spoken language assessment to promote spoken language assessment grade.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a display device for three-dimensional characters according to a first embodiment of the present disclosure. The display device of the three-dimensional character may include:

a first obtaining unit 401, configured to obtain the selected learning content;

In some examples, the display apparatus described in fig. 4 may be transferred to an electronic device, and the electronic device may locate a learning module selected by a finger, a pen, or a voice of a user, and use the learning module selected by the finger, the pen, or the voice of the user as a corresponding learning module of the user. For example, the electronic device may use a camera (e.g., a camera) to capture a learning module selected by a finger or a writing pen of a user as a learning module corresponding to the user; alternatively, the electronic device may use a sound pickup device (e.g., a microphone) to pick up a learning module selected by the voice uttered by the user as the learning module corresponding to the user. In some embodiments, the camera device (e.g., a camera) may be disposed on a ring worn by a finger of a user, and when the ring detects that the finger of the user worn by the ring is straightened, the ring may start the camera device (e.g., the camera) to shoot a learning module selected by the finger of the user, and the ring transmits the shot learning module selected by the finger of the user to the electronic device, so that the electronic device may determine the learning module corresponding to the user. By the implementation of the implementation mode, power consumption caused by the fact that the electronic equipment shoots the learning module selected by the finger of the user can be reduced, and therefore battery endurance of the electronic equipment can be improved.

Therefore, the display device for the three-dimensional characters depicted in fig. 4 can improve the man-machine interaction of the students when writing words, thereby being beneficial to improving the enthusiasm and interest of the students when writing words.

In addition, the display device for displaying the three-dimensional character described in fig. 4 can reduce power consumption caused by the learning module selected by the user's finger when the electronic device shoots, so that the battery life of the electronic device can be improved.

In addition, by implementing the display device of the three-dimensional character described in fig. 4, a supervisor (such as a teacher or a parent) of a user can flexibly select a learning module for the user, and does not cause sound interference to surrounding people in the process of selecting the learning module for the user.
