It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flowchart of a teaching information feedback method according to an embodiment of the present invention, which is suitable for feeding back the blackboard writing teaching content of a learner to the learner during a teaching process, and the method may be executed by a teaching information feedback device, where the device may be implemented by software and/or hardware and is generally integrated into an intelligent teaching device.
It should be noted that the application scenarios of the method provided in this embodiment may be: teaching processes in traditional or small classrooms, lectures or teaching in large classrooms or conference rooms with the nature of writing on a blackboard, and the like. The teaching information feedback method based on the embodiment can effectively feed back the teaching content of a teacher or a speaker to a speaker with a demand.
As shown in fig. 1, a teaching information feedback method provided in an embodiment of the present invention includes the following operations:
the method steps in the embodiment are mainly applied to the intelligent teaching equipment provided by the embodiment of the invention. The intelligent teaching equipment can be used as a combination of an electronic whiteboard and a writing board, and can be used for teaching content writing on the writing board and electronic teaching information display on the electronic whiteboard for a teacher.
In this embodiment, the intelligent terminal device may be disposed on a podium where a teacher is located in a teaching place or a wall of the podium, and the intelligent terminal device may establish a communication connection with at least one mobile terminal in the teaching place through a setting manner (such as WiFi or bluetooth), so that information interaction with the mobile terminal may be implemented. The mobile terminal can be regarded as a handheld terminal owned by a learner and can be electronic equipment such as a mobile phone, a tablet personal computer and a smart watch.
S101, when an information acquisition request sent by a mobile terminal is received, determining the current state of a camera.
In this embodiment, the camera may be specifically considered as a part of the intelligent teaching device, and is mainly used for capturing teaching contents on a writing board in the intelligent teaching device. The current state of the camera may specifically refer to a state in which the camera is in a sleep state or a working state when receiving an information acquisition request sent by the mobile terminal.
In this embodiment, the intelligent terminal device may receive information acquisition requests sent by multiple mobile terminals at the same time, and in this embodiment, the mobile terminals performing information interaction may be distinguished specifically by using the terminal identity carried in the information acquisition requests. Specifically, this step may detect a current state of the camera when receiving an information acquisition request sent by the mobile terminal, so that it may be determined whether the camera is currently in a sleep state.
S102, if the current state of the camera is a dormant state, controlling the camera to enter a working state of capturing teaching contents on a writing board, and determining a target teaching content image corresponding to the information acquisition request from the captured teaching content image.
Specifically, in this step, after it is determined that the camera is currently in the sleep state, it is equivalent to first triggering and starting the camera to enter a working state based on the received information acquisition request, and after the camera enters the working state, the camera may perform image acquisition and capture on teaching contents of a teacher's writing on a writing board, and at this time, a target teaching content image corresponding to the information acquisition request may be determined from the captured teaching content image.
It can be understood that, if information acquisition requests sent by a plurality of mobile terminals are currently received, the camera may be started to enter the working state according to the information acquisition request with the earliest receiving time, and then the target teaching content image corresponding to each information acquisition request is determined from the captured teaching content images respectively. The present embodiment can perform acquisition of target teaching content in the captured teaching content image according to the time at which the information acquisition request is received.

In this embodiment, after determining the target teaching content image corresponding to the information acquisition request, the target teaching content may be fed back to the mobile terminal corresponding to the information acquisition request. It is understood that the present embodiment does not directly perform feedback of information after performing S102, but performs feedback of information based on the feedback timing set in the information feedback condition.
Illustratively, if the feedback timing in the information feedback condition is real-time feedback, the target teaching content image may be fed back to the mobile terminal immediately after executing S102; in addition, a special feedback requirement may be set in the information feedback condition, and the feedback of the target teaching content image to the mobile terminal may be performed only after the set feedback requirement is met.
The teaching information feedback method provided by the embodiment of the invention is mainly applied to intelligent teaching equipment, can trigger the camera to capture teaching contents according to the received information acquisition request of the mobile terminal, and can select a target teaching content image corresponding to the information acquisition request from the captured teaching contents and feed back the target teaching content image to the mobile terminal.

Example two
Fig. 2 is a schematic flowchart of a teaching information feedback method according to a second embodiment of the present invention. The second embodiment of the present invention is optimized based on the above embodiments, and in this embodiment, further optimization increases: and if the camera is in the working state of capturing the teaching content on the writing board, directly determining the target teaching content corresponding to the information acquisition request from the captured teaching content image.
Further, the present embodiment further optimizes "determining the target teaching content corresponding to the information acquisition request from the captured teaching content image" to determine the reception time when the information acquisition request is received; and in the teaching content image set captured by the camera, determining the teaching content image corresponding to the receiving time as the target teaching content image of the information acquisition request.
In this embodiment, the target teaching content image is further fed back to the mobile terminal according to a set information feedback condition, and is optimized as follows: if the information feedback condition is information real-time feedback, feeding back the target teaching information to the mobile terminal in real time after determining a target teaching content image corresponding to the information acquisition request; if the information feedback condition is information summarizing feedback, target teaching content images corresponding to all information acquisition requests sent by the mobile terminal are cached in time sequence, and all cached target teaching contents are fed back to the mobile terminal after the summarizing feedback condition is achieved.
In addition, this embodiment has also optimized and increased: and if the information acquisition request of the mobile terminal is not received within the set time period, controlling the camera to enter a dormant state.
As shown in fig. 2, a teaching information feedback method provided in the second embodiment of the present invention specifically includes the following operations:
s201, receiving an information acquisition request sent by a mobile terminal.
For example, as long as the intelligent teaching device in this embodiment is in a power-on state, the operations in this step may be performed, and the information acquisition requests sent by at least one mobile terminal may also be received simultaneously or sequentially.
S202, judging the current state of the camera when the information acquisition request is received, and if the current state of the camera is in a dormant state, executing S203; if yes, go to step S204.
For example, the camera on the intelligent teaching device in the embodiment is not in a real-time working state, so that the current state of the camera can be determined when the information acquisition request is received. The current state may be a dormant state in which the teaching content is not captured, or an operating state in which the teaching content is captured.
S203, controlling the camera to enter a working state of capturing teaching contents on the writing board, and executing the subsequent operation of S204.
For example, in this step, specifically, when the camera is in the sleep state, the camera is controlled to operate through triggering of the information acquisition request, and after the camera is operated, the determination operation of the target teaching content image corresponding to the information acquisition request in S204 and S205 may be executed.
S204, determining the receiving time when the information acquisition request is received.
For example, in this step, after the camera is currently in the working state, the receiving state of the information acquisition request may be analyzed, and the receiving time in the information acquisition request may be determined, where the receiving time in this step may be regarded as a specific time value.
And S205, in the teaching content image set captured by the camera, determining the teaching content image corresponding to the receiving time as the target teaching content image of the information acquisition request.
It can be understood that if the camera is always in the working state, the camera always captures the teaching content in real time and forms a teaching content image set containing teaching content images; if the camera is in the operating state from the sleep state based on S203, it can be considered that the camera starts capturing the teaching content at the time when the operating state is performed, and a teaching content image set including the teaching content image can be formed as well.
This step may determine the capturing time of each teaching content image in the teaching content image set according to the receiving time of the received information acquisition request (which may also be understood as the sending time of the information acquisition request sent by the mobile terminal, and this embodiment preferably considers that the transmission rate of the information acquisition request is extremely fast and ignores the transmission consumption time by default).
In the step, the teaching content image with the capture time equal to the receiving time can be determined as the target teaching content image of the information acquisition request corresponding to the receiving time; in addition, if there is no teaching content image in the teaching content image set whose capture time is identical to the reception time, the teaching content image whose capture time and reception time differ by a set time range may be determined as the target teaching content image of the information acquisition request corresponding to the reception time.
It should be noted that, if the information acquisition requests of multiple mobile terminals are received at the same time in S201, the terminal identification included in the information acquisition request may be used as a tag of the reception time when the reception time is determined, so that a corresponding relationship between the mobile terminal and the information acquisition request, the reception time, and the target teaching content image may be established, and further, normal feedback of the subsequent target teaching content image is ensured.
And S206, if the information feedback condition is information real-time feedback, feeding back the target teaching information to the mobile terminal in real time after determining the target teaching content image corresponding to the information acquisition request.
In this step and S207, information feedback operations corresponding to two different information feedback conditions are respectively given. Specifically, the information feedback condition set in this step is information real-time feedback, that is, feedback of the target teaching content image is performed on the sending end (mobile terminal) of the received information acquisition request in real time.
In this embodiment, the information feedback condition is specifically set at the intelligent teaching device side, and the feedback condition can be dynamically set according to the resource load condition of the intelligent teaching device. Illustratively, when the current resource load of the intelligent teaching equipment is monitored to be less than or equal to a set value, an information feedback condition can be set as information real-time feedback; on the contrary, if the current resource load is larger than the set value, the workload of the intelligent teaching equipment is buffered, and the information feedback condition is set as the information summarizing feedback.
And S207, if the information feedback condition is information summarizing feedback, caching target teaching content images corresponding to all information acquisition requests sent by the mobile terminal in a time sequence, and feeding back all cached target teaching contents to the mobile terminal after the summarizing feedback condition is met.
In this embodiment, when performing the information summarizing feedback, which is equivalent to repeatedly performing the operations in S201 to S205, in order to ensure the accuracy of the information feedback, in this embodiment, it is preferable that the mobile terminal that has sent the information obtaining request establishes an information cache table, where the information cache table includes the receiving time (which can be used as an identification tag of the information obtaining request, and generally, the corresponding receiving time is different for the information obtaining request sent by the same mobile terminal) of each information obtaining request sent by the mobile terminal and the target teaching image content corresponding to the information obtaining request at the receiving time (one receiving time only corresponds to and determines one target teaching image content).
The set information cache table in this embodiment is equivalent to caching target teaching content images corresponding to each information acquisition request sent by the mobile terminal in a time sequence.
In addition, the summarized feedback condition set by the embodiment may be: the current resource capacity of the intelligent teaching equipment is smaller than a set value; the camera of the intelligent teaching equipment can also be in a dormant state. When the set summarizing feedback condition is met, all target teaching content images (possibly one target teaching content image) in the information cache table corresponding to each mobile terminal (possibly one mobile terminal) can be fed back to the mobile terminal in time sequence.
S208, monitoring whether an information acquisition request of the mobile terminal is received within a set time period, if so, returning to S204; if not, S209 is executed.
The operations of S201 to S207 described above correspond to the whole process of receiving the image feedback of the target teaching content from the information acquisition request, and this step corresponds to a loop determination performed on the whole process, and the determination condition starts to time every time the information acquisition request is newly received, and if the information acquisition request of the mobile terminal is received when the time accumulated value of the time is less than or equal to the set time period, the operation may return to S204 for repeated execution, and the time is counted again from the present time, and the determination operation of this step is repeatedly performed; if the information acquisition request of the mobile terminal is not received after the counted time accumulated value is greater than the set time period, the operation of S209 may be performed.
And S209, controlling the camera to enter a dormant state.
In the step, when the accumulated value of the timed time is greater than the set time period, the camera is triggered and controlled to be in a dormant state, so that the power consumption and the resource occupancy rate of the intelligent teaching equipment can be better reduced.
According to the teaching information feedback method provided by the embodiment II of the invention, the specific operation of the camera in the working state is optimized and increased; meanwhile, the determination process of the target image and the specific operation process of the target image feedback are embodied; in addition, the conversion operation of the working state of the camera is optimized and increased. By using the method, different operations can be intelligently started according to the state of the camera when the information acquisition request is received, simultaneously, the target teaching content needing to be fed back to the mobile terminal user can be determined according to the receiving time of the information acquisition request, and in addition, the feedback time for feeding back the information to the mobile terminal user can be determined. Through the operation, the personalized feedback of the teaching contents to the mobile terminal user is effectively ensured, the manual recording and manual photographing of the teaching contents by the mobile terminal user in the teaching process are avoided, meanwhile, the tedious operation that the mobile terminal user screens useful information in a large amount of teaching information is avoided, and the teaching performance of the intelligent teaching equipment is ensured.

The method is suitable for acquiring the writing contents of the teacher in the teaching process, and can be executed by a teaching information feedback device, wherein the device can be realized by software and/or hardware and is generally integrated on a mobile terminal held by a listener.

it should be noted that the application scenario of the method provided in this embodiment may be described as follows: in the teaching place with the intelligent teaching equipment, a user can establish communication connection between the handheld mobile terminal and the intelligent teaching equipment in a set mode, and then information interaction between the mobile terminal and the intelligent teaching equipment is realized.
And S301, generating an information acquisition instruction according to the trigger of the user.
According to the embodiment, the set information interaction interface can be entered after the mobile terminal is connected with the intelligent teaching equipment, and the corresponding trigger button is arranged in the information interaction interface, so that a user can perform trigger operation of obtaining teaching information at any time.
For example, the user may trigger the trigger button when the teacher teaches the blackboard writing and finds that teaching content helpful to the user exists on the writing board of the intelligent teaching device. In this step, an information acquisition instruction corresponding to the current time may be generated according to the trigger operation of the user on the trigger button.
And S302, sending an information acquisition request to the intelligent teaching equipment based on the information acquisition instruction.
The step can send an information acquisition request to the intelligent teaching equipment through the control of the information acquisition instruction. It can be understood that the information obtaining request specifically includes a terminal identity of the mobile terminal itself, such as an international mobile equipment identity. In addition, the user can trigger the trigger button immediately according to the useful teaching content in the teaching process, and the trigger time and the trigger times are not limited in the embodiment.
S303, receiving a target teaching content image corresponding to the information acquisition request fed back by the intelligent teaching equipment in real time; or receiving at least one target teaching content image fed back by the intelligent teaching equipment based on the summary feedback condition.
The receiving time of the target teaching content image is not limited in the step, and is determined according to the feedback time of the intelligent teaching equipment, and information can be received based on the step as long as the feedback of the target teaching content exists. Illustratively, the target teaching content image fed back by the intelligent teaching device in real time can be received in real time; after the operations of S301 and S302 are repeatedly executed for multiple times to send multiple information acquisition requests, when the intelligent teaching device meets the summarized feedback condition, target teaching content images corresponding to the multiple information acquisition requests fed back by the intelligent teaching device may be received.
It should be noted that the present embodiment may present the received content in real time and store the content in time sequence.
The teaching information feedback method provided by the third embodiment of the invention is particularly applied to a mobile terminal held by a user (hearer), and firstly, an information acquisition instruction can be generated according to the triggering of the user; then, an information acquisition request can be sent to the intelligent teaching equipment based on the information acquisition instruction; and finally, target teaching content images fed back by the intelligent teaching equipment can be received in real time, and at least one target teaching content fed back by the intelligent teaching equipment in a summary manner can also be received. By using the method, the information interaction between the mobile terminal and the intelligent teaching equipment is equivalently realized, the user can simply and effectively acquire the required target teaching content only by triggering, manual recording or manual photographing is not needed, the class attending efficiency of the user is greatly improved, and meanwhile, the complicated operation of screening the required teaching content in a large amount of teaching information is avoided.
