Of course, the terminal device may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, and the like, which are not described herein.
It will be appreciated by those skilled in the art that the terminal structure shown in fig. 1 is not limiting of the terminal and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and a tutorial program may be included in the memory 1005, which is a type of computer storage medium.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting a background teaching device and performing data communication with the background teaching device; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call the tutorial program stored in the memory 1005 and perform the following operations:
Acquiring learner information of a learning terminal according to a teaching request sent by the learning terminal;
determining teaching videos matched with the learner information from a teaching video library;
determining a play starting position of the teaching video according to the learning video of the learning terminal;
and superposing the teaching video in the learning video, and playing from the playing starting position of the teaching video.
Referring to fig. 2, the present invention provides a teaching method, in a first embodiment of the teaching method, the teaching method includes the steps of:
step S10, obtaining learner information of a learning terminal according to a teaching request sent by the learning terminal;
the embodiment can be applied to a cloud game platform, and the cloud game platform can be a game server arranged at a far end. The game can run on a cloud server, the calculation rendering of the game is realized through the server, the game picture is encoded in real time, and the video stream pushed to the game terminal is generated. The game terminal can be a learning terminal used by a learner, and after receiving the audio and video stream, the game terminal decodes and plays the audio and video stream to a user, and simultaneously collects an operation instruction triggered by the user and sends the operation instruction to the cloud server, so that game experience is realized.
When a user plays a game as a learner on the learning terminal, a corresponding teaching request can be triggered, and the learning terminal can send the teaching request to the server, so that the server can acquire learner information corresponding to the learning terminal according to the teaching request. It will be appreciated that the learner information may include information parameters, such as the name of the game currently being played by the learner, the character of the game, the level of the game, the current progress, and the availability of the operation, etc., that are capable of reflecting the learner's game capabilities.
Step S20, determining teaching videos matched with the learner information from a teaching video library;
after the server acquires the learner information, the teaching video which is matched with the game capability of the learner can be determined from the learner information. According to the learner information of the learner, the teaching video of the learner with smaller difference from the game operation level of the current learner in the same game level can be determined from the teaching videos in the teaching video library. The learner can effectively improve the game operation capability of the learner by watching the teaching video with the operation level being relatively close. The teaching videos obtained by server matching can be one or more.
It can be understood that, because the calculation and rendering of the game are completed by the server, the server side stores not only the game videos of all players in the game process, but also the player operation steps and operation instructions corresponding to each game video. After the operation steps and the operation instructions of the player are identified in the corresponding game video, the game video of the player can be converted into teaching video and stored in a teaching video library. The learner can watch the original game video of the learner and can watch the actual operation steps and operation instructions of the learner through watching the teaching video, so that the learner can intuitively know the corresponding relation between the game operation and the operation result, and the understanding of the learner on the operation mode is improved.
It should be noted that different games can be experienced on the learning terminal, and the server side can also set different teaching video libraries for different games respectively. When the server side acquires the learner information, the game name of the game which the learner currently enters can be determined from the learner information, and a teaching video library corresponding to the game name is determined, wherein the teaching video in the teaching video library is the teaching video of the game. Through obtaining the game name, the matching range of the teaching video can be reduced, and the matching efficiency is improved. Further, the learner information may further include a game character used by the learner in the game, and the server may further screen out a teaching video corresponding to the game character from a teaching video library corresponding to the game name according to the game character, so as to continuously narrow down a range of the teaching video for matching. Namely, the learner information can select the teaching videos meeting the conditions from the teaching video library, so that the matching range of the teaching videos is reduced, and the matching speed is improved.
Step S30, determining a play starting position of the teaching video according to the learning video of the learning terminal;
after the server determines the teaching video matched with the learner information, if the learner does not start the game currently, the corresponding teaching video can be directly played. If the learner starts the game, the server also needs to determine the play starting position corresponding to the teaching video according to the current game progress of the learner. For example, when the learner has started the game and the game progress of the current level is 50%, if the teaching video is played from the beginning, the progress of the teaching video does not coincide with the current game progress of the learner. The server needs to determine the corresponding playing progress in the teaching video according to the video image of the current learning video of the learner, so that the teaching video can be played from the current game progress of the learner.
And S40, superposing the teaching video in the learning video, and playing from the playing starting position of the teaching video.
After determining the play start position of the teaching video, the server can superimpose the video stream of the teaching video in the game video stream pushed to the learning terminal, and the learning terminal decodes the superimposed video stream and plays the video stream, so that the teaching video can be synchronously displayed while the learning video is displayed. The learner can realize linkage teaching according to the displayed teaching video, for example, after watching the teaching video, the learner can trigger corresponding first input, and after receiving the first input, the learning terminal can respond to the first input and generate corresponding learning video, so that the learner can determine an operation result corresponding to the first input by watching the learning video. The first input may be a key operation, a click operation, a track sliding operation, a gesture operation, or the like, which is triggered by the learner on the learning terminal. The operation mode of a learner is learned through the teaching video, and the corresponding operation result is obtained in the learning video through practicing the corresponding operation, so that the game operation capability is improved.
It will be appreciated that the teaching video may be superimposed within a portion of the display area in the learning video. When a user watches the learning video, the part of the display area displays the teaching video, the area other than the teaching video displays the learning video, after learning the operation mode of the learner according to the teaching video, the learner can immediately adjust own operation steps and operation instructions, practice is carried out in similar scenes, and an operation result corresponding to the adjusted operation mode is determined according to the corresponding display content of the learning video.
In this embodiment, the server may receive the teaching request sent by the learning terminal, obtain learner information of the learning terminal, determine a plurality of teaching videos to be matched from the teaching video library according to the learner information, and select a most matched teaching video from the plurality of teaching videos. After determining the corresponding learning progress according to the current learning video of the learner, the server can correspondingly determine the playing progress of the teaching video as the playing starting position for playing to the learner. When the server sends the video stream to the learning terminal, the teaching video can be overlapped in the video stream, so that a learner can synchronously watch the learning video and the teaching video on the learning terminal, and the learner can learn from the operation mode of the learner identified in the teaching video, thereby effectively improving the game operation capability of the learner.
Further, based on the first embodiment of the present invention, a second embodiment of the teaching method of the present invention is provided, referring to fig. 3, fig. 3 is a schematic flow chart of the second embodiment of the teaching method of the present invention, in this embodiment, the step S30 of determining, according to a learning video of the learning terminal, a play start position of the teaching video includes:
step S31, converting the continuous frame images of the learning videos into a first characteristic character string group, and acquiring a second characteristic character string group corresponding to the continuous frame images of each teaching video from the teaching video library;
step S32, matching the first characteristic character string group with all the second characteristic character string groups, and determining a matched characteristic character string group from the second characteristic character string groups meeting the matching requirement;
and step S33, determining a corresponding teaching video according to the matched characteristic character string group, and taking the playing position of the continuous frame image corresponding to the matched characteristic character string group as the playing starting position of the teaching video.
In this embodiment, the manner in which the server determines the play start position of the teaching video according to the video progress of the learning video may be that, in the current learning video, each frame image of the continuous frame images is converted into a corresponding feature string, and the corresponding feature strings are ordered according to the sequence of the continuous frame images, so as to obtain the first feature string group.
When the matched teaching videos are obtained from the teaching video library, each frame image in the teaching videos is converted into a corresponding characteristic character string through the same conversion algorithm, and the characteristic character strings are correspondingly ordered according to the display sequence of each frame image in the teaching videos, so that a second characteristic character string group is obtained. If the number of the teaching videos obtained by matching is multiple, each teaching video is converted into a corresponding second characteristic character string group, so that multiple second characteristic character string groups are obtained.
The first feature string group includes feature strings corresponding to continuous frame images of a preset frame number, for example, the preset frame number may be 60, and the first feature string group includes a string group formed by 60 feature strings corresponding to 60 continuous frame images in sequence. The second character string group is a character string group formed by the character strings corresponding to all continuous frame images in the teaching video in sequence. It will be appreciated that the number of feature strings in the second set of feature strings is much greater than the first set of feature strings.
When the number of the matched teaching videos is determined to be one in the teaching video library, the first characteristic character string group and the second characteristic character string group are matched, namely, continuous characteristic character strings with preset frame numbers in the first characteristic character strings are matched with the second characteristic character string group, whether continuous characteristic character strings with the same preset length in the second characteristic character string group are consistent with the first characteristic character string group or not is judged, and the preset length can be corresponding to the preset frame numbers or can be adjusted according to the preset frame numbers. For example, when the preset frame number is 60, the first feature string group is 60 continuous feature strings, and it is detected whether 60 continuous feature strings are consistent with the first feature string group in the second feature string group. If the second feature string group has 60 continuous feature strings, the continuous feature strings are the matching feature string groups in the second feature string group. The continuous frame images corresponding to the matched characteristic character string group in the teaching video are the playing progress of the teaching video synchronized with the learning video, so that the playing starting position of the teaching video is determined.
If the second characteristic string group does not have the continuous characteristic string completely consistent with the first characteristic string group, the second characteristic string group is not matched with the first characteristic string group by 100%. In an alternative embodiment, the number of frames of the continuous character strings to be matched may be adjusted, for example, 60 continuous character strings are reduced to the nearest 30 continuous frame images, that is, the first characteristic character string group is 30 continuous characteristic character string groups at this time, and the first characteristic character string group is matched with the second characteristic character string group, so as to determine whether the same 30 continuous characteristic character string groups exist in the second characteristic character string group. If the same 30 continuous characteristic character string groups exist in the second characteristic character string group, it can be determined that continuous frame images corresponding to the 30 continuous characteristic character string groups in the second characteristic character string group correspond to the current progress of the learning video at this time, and the play starting position of the teaching video is determined.
Further, if the continuous characteristic strings completely consistent with the first characteristic string set do not exist in the second characteristic string set after the preset frame number is adjusted, the matching degree requirement can be reduced. For example, the matching degree is reduced to 95%, when the preset frame number is 60, 60×95% =57, the first 57 continuous characteristic strings in 60 continuous characteristic strings in the first characteristic string group are taken, and whether the corresponding 57 continuous characteristic strings in the second characteristic string group are consistent with the first 57 continuous characteristic strings is judged; or taking the last 57 continuous characteristic strings in the 60 continuous characteristic strings, and judging whether the corresponding 57 continuous characteristic strings in the second characteristic string group are consistent with the last 57 continuous characteristic strings.
When the second feature string group has the corresponding continuous feature strings, the matching is determined to be successful, if the second feature string group does not have the corresponding continuous feature strings, the matching degree can be further reduced to 90%, 85% and 80%, and whether the second feature string group has 54, 51 and 48 continuous feature strings which are consistent with the 54, 51 and 48 continuous feature strings in the first feature string group is judged.
It can be understood that, in the above-mentioned cyclic matching method for reducing the matching degree, a matching method for adjusting the preset number of frames may be further added, for example, when the matching degree is reduced to 95% and the preset number of frames is 60, if there are no corresponding 57 continuous character strings in the second character string group, the preset number of frames may be further reduced, for example, reduced to 30, and it is determined whether there are corresponding 28 continuous character strings in the second character string group. And when the preset frame number is reduced and still fails to be matched, restoring the preset frame number to an initial value, reducing the matching degree to 90%, and then re-matching. And circularly matching the first characteristic character string group with the second characteristic character string group by continuously adjusting the matching degree and adjusting the preset frame number until the continuous characteristic character strings are determined from the second characteristic character string group, so that the corresponding continuous frame images, namely the playing starting positions of the teaching video, are determined.
When the number of continuous feature strings of the preset frame number is reduced to match, if the continuous feature string is the first 30 of the 60 continuous feature strings, 30 continuous feature strings matched with the continuous feature strings in the second feature string group correspond to the first 30 continuous feature strings in the first feature string group, and at this time, a frame image corresponding to the video progress of the learning video is actually the 60 th feature string, that is, the last feature string of the 30 continuous feature strings is further 30 frames later. Therefore, the 30 th character string successfully matched in the second character string group is 30 frames later, namely the play starting position of the teaching video corresponding to the video progress of the learning video.
It can be appreciated that when the number of the matched teaching videos is determined to be greater than one in the teaching video library, each teaching video can be respectively matched with the learning video. When the same continuous characteristic character string exists in the second characteristic character string group of a certain teaching video, the teaching video is the best matched teaching video in a plurality of teaching videos.
Further, based on the second embodiment of the present invention, a third embodiment of the teaching method of the present invention is provided, in this embodiment, the step S31 of converting the continuous frame images of the learning video into the first feature string group, and obtaining the second feature string group corresponding to the continuous frame images of each teaching video from the teaching video library includes:
Step S311, dividing a plurality of background areas from a learning video of the learning terminal, and converting continuous frame images of each background area into a corresponding first background area characteristic character string group;
step S312, a corresponding background area is divided from each teaching video in the teaching video library, and continuous frame images of the background area of each teaching video are converted into a corresponding second background area characteristic character string group;
the step S32, the step of matching the first feature string set with all the second feature string sets, and determining the matching feature string set from the second feature string sets that meet the matching requirement, includes:
step S321, selecting a background area as a background area to be matched, sequentially matching a first background area characteristic string group corresponding to the background area to be matched with a second background area characteristic string group, and judging whether the second background area characteristic string group meeting the matching requirement exists or not; the matching requirement is that the matching degree of the first background area characteristic character string group and the second background area characteristic character string group reaches a preset matching threshold;
Step S322, when a second background area characteristic string group meeting the matching requirement exists, determining the matching characteristic string group from the second background area characteristic string group meeting the matching requirement;
step S323, when there is no second background area feature string group meeting the matching requirement, updating the background area to be matched according to the preset background area selection sequence, and returning to the execution step: and sequentially matching the first background area characteristic character string group corresponding to the background area to be matched with the second background area characteristic character string group.
In this embodiment, since the manner in which the learner operates the game character during the game is not exactly the same as that of the learner, even under the same game progress, the frame image of the teaching video does not exactly correspond to the frame image of the learning video, that is, the feature character string corresponding to the frame image of the teaching video is not identical to the feature character string corresponding to the frame image of the learning video at this time. However, it is understood that, during the game, the background area of the learning video, which is not changed by the operation mode of the game character, should correspond to the background area of the teaching video, except that the image area affected by the game character is different from the image of the teaching video due to the difference of the operation mode of the game character by the learner. That is, under the same game progress, the background area of the learning video is consistent with the background area of the teaching video, and the feature character strings corresponding to the two background areas respectively are also consistent. That is, when a frame image according to the current game progress of the learning video is matched with the teaching video to obtain a play start position of the teaching video, only a background area in the frame image of the learning video is converted into a background area characteristic string, and a matching comparison is performed with the background area characteristic string corresponding to the frame image of the teaching video.
It should be noted how the background area is determined in the display area of the teaching video. The server can acquire a plurality of teaching videos with the same game names, the same game roles and the same game level, respectively encode each teaching video, and if the frame image is a P frame, perform discrete cosine transform DCT processing on the code stream of the P frame. The region which is completely consistent in the frame images of the teaching videos is the background region of the game stage, and the region which is inconsistent in the frame images is the non-background region formed by different teaching persons due to different operation modes.
In an optional embodiment, a plurality of background areas may be pre-divided in the learning video of the learning terminal, and accordingly, the same background areas are divided in the teaching video in the same manner. After determining a background area as the background area to be matched, the feature character string matching can be performed on the background area frame image to be matched of the learning video and the background area frame image to be matched of the teaching video. For example, after dividing the background area of the learning video into a left background area, an upper background area, and a right background area. The continuous frame images of the left background area of the learning video can be converted into continuous character strings to form corresponding first background area character string groups. Likewise, successive frame images of the left background region of the teaching video are converted into a second background region feature string set. And matching the continuous characteristic strings in the first background area characteristic string group with the second background area characteristic string group, and judging whether the same continuous characteristic strings exist in the second background area characteristic string group.
If the continuous characteristic strings exist, the continuous characteristic strings matched with the first background area characteristic string group in the second background area characteristic string group meeting the matching requirement can be used as the matching characteristic string group, and continuous frame images corresponding to the continuous characteristic strings in the matching characteristic string group are the playing starting positions of the teaching video. If the background region does not exist, the background region to be matched can be updated according to the preset background region selection sequence, for example, the continuous frame images of the upper background region of the learning video are converted into continuous characteristic character strings according to the sequence of the left background region, the upper background region and the right background region, and the continuous frame images of the upper background region of the teaching video are converted into continuous characteristic character strings to be matched again. In the process of sequentially matching the left background area, the upper background area and the right background area, if the same continuous characteristic character strings exist in the teaching video, the successful matching can be determined, and the matching process can be exited.
Further, based on the first embodiment of the present invention, a fourth embodiment of the teaching method of the present invention is provided, in this embodiment, the step S40 of superimposing the teaching video in the learning video, and playing from a play start position of the teaching video includes:
Step S41, determining a time delay time length according to a preset margin rule;
and step S42, superposing the teaching video in the learning video, carrying out delay processing on the playing starting position of the teaching video according to the delay time length, and playing from the playing starting position after the delay processing of the teaching video.
In this embodiment, when the server obtains the current game progress of the learning video of the learning terminal, the server determines the play start position of the teaching video and pushes the superimposed video stream, and a certain operation processing time is required to be consumed. At this time, the learner still continues to play the game, and the progress of the game for learning the video also continues to advance. Therefore, after the play start position of the teaching video is determined, the game progress in the learning video is not at the original game progress position, and the play start position of the teaching video also needs to be delayed, so that the play progress of the teaching video can keep up with the game progress of the learning video.
In addition, even if the playing progress of the teaching video is completely consistent with the game progress of the learning video, a certain response time exists after the learner sees the operation after the teaching video, and even if the learner immediately performs the corresponding operation after seeing the teaching video, a corresponding delay exists. Therefore, the playing progress of the teaching video should slightly precede the game progress of the learning video so that the learner has a certain reaction time after seeing the teaching video. The server can store allowance rules in advance, after the play starting position of the teaching video is determined, delay time can be determined according to the allowance rules, after the play starting position of the teaching video is correspondingly delayed according to the delay time, the play is performed from the play starting position after the delay processing, so that the operation processing time of the server does not influence the progress matching of the learning video and the teaching video, and corresponding response time can be reserved for learners.
Further, based on the fourth embodiment of the present invention, a fifth embodiment of the teaching method of the present invention is provided, in this embodiment, the step S41 of determining the delay time length according to the preset margin rule includes:
step S411, when determining the play start position of the teaching video, obtaining a corresponding operation duration;
step S412, generating a delay time according to the operation time and a preset initial delay value.
In this embodiment, the server may obtain a corresponding operation duration when determining the play start position of the teaching video according to the prestored margin rule, and superimpose a preset start delay value on the basis of the operation duration to generate the delay duration. The operation time length is the operation time spent from the beginning of the server receiving the teaching request sent by the learning terminal to the determination of the playing starting position of the teaching video by the server. The preset start delay value may be 1 second. When the teaching video is superimposed in the learning video, the influence of the server operation process on the game progress can be eliminated by delaying the corresponding operation time, and the response time can be provided for the learner by delaying the corresponding start delay value, so that the learner can immediately practice through operation in the learning video after seeing the operation mode of the teaching video.
Further, based on the above-mentioned first embodiment of the present invention, a sixth embodiment of the teaching method of the present invention is provided, referring to fig. 4, and fig. 4 is a schematic flow chart of the sixth embodiment of the teaching method of the present invention, in this embodiment, the step S40 of superimposing the teaching video in the learning video, and after the step of playing from the playing start position of the teaching video, further includes:
step S50, acquiring operation parameters of the learning terminal every preset period;
step S51, determining a video adjustment amount according to the operation parameter and a preset advance adjustment algorithm;
and step S52, adjusting the playing progress of the teaching video according to the video adjustment amount.
In this embodiment, the response speed of different learners is different, so that the adaptation degree to the teaching video is also different. After the teaching video is delayed to be played according to the preset initial delay value, the playing progress of the teaching video can be adjusted according to the learning ability and the operation level of a learner, so that the playing progress of the teaching video is more suitable for the learner.
When a learner watches the teaching video, the operation parameters of the learning terminal can be acquired every preset period. The operation parameter may be an operation effective ratio l_p of the learner, which is an effective operand/total number of operations. After determining the operation effective ratio of the learner, the operation effective ratio can be compared with the operation effective ratio obtained by sampling the previous period, so as to determine the progress adjustment mode of the teaching video. For example, when it is determined that the operation effective ratio obtained by the current sampling is increased compared with the operation effective ratio obtained by the previous sampling, the playing progress of the teaching video can be increased and adjusted, that is, the advance of the teaching video relative to the learning video is increased. Correspondingly, if the operation effective ratio of the present time is reduced compared with the operation effective ratio of the last sampling, the advance of the teaching video relative to the learning video can be reduced.
In an alternative embodiment, after each sampling to obtain the operational effective ratio of the learner, the lead parameter TC, tc= (the last sampling point l_p-the previous sampling point l_p) ×t, T is the preset period of the interval.
Video adjustment amount (C) =f (0.2, tc, 0.5);
wherein F represents a TC value when TC is between 0.2 and 0.5 or-0.5 and-0.2; c is 0.5 when TC is more than 0.5, and C is-0.5 when TC is < -0.5; c is-0.2 at-0.2 < TC < 0; at 0< TC <0.2, C is taken to be 0.2.
After the video adjustment quantity C is calculated, if C >0, increasing the video advance quantity by C; if C <0, the video advance is reduced by C.
It will be appreciated that when video adjustment is performed, a corresponding special rule may also be set, so that when the corresponding rule is satisfied, the special adjustment is performed according to the special rule. For example, an adjustment threshold of the operation effective ratio may be preset, and when the sampled operation effective ratio is greater than the adjustment threshold, the playing progress of the teaching video may not be adjusted. The adjustment may be omitted when the value is-0.2 < TC < 0.2. It is also possible to arrange that if TC is between 0.2 and 0.5 three times in succession, no adjustment is made from the third time. Meanwhile, since the normal reaction time of the human body is at least higher than 0.2 seconds, the video advance of the teaching video relative to the learning video is required to be not less than 0.2 seconds no matter how the adjustment is performed.
Further, based on the above-mentioned first embodiment of the present invention, a seventh embodiment of the teaching method of the present invention is provided, referring to fig. 5, fig. 5 is a schematic flow chart of the seventh embodiment of the teaching method of the present invention, in this embodiment, the step S20 of determining, from a teaching video library, a teaching video matching with the learner information includes:
step S21, obtaining the information of the teaching person corresponding to each teaching video from the teaching video library;
step S22, respectively calculating matching parameters of each piece of teaching person information and the learner information according to a preset matching algorithm;
and S23, determining the teaching video corresponding to the matching parameter with the highest matching degree as the teaching video matched with the learner information.
In this embodiment, after obtaining the learner information of the learning terminal, the server may obtain the learner information corresponding to each teaching video from the teaching video library, and calculate the matching parameters of each learner information and the learner information according to a preset matching algorithm. After the matching parameters of all the teaching videos and the learning videos are calculated, the teaching video corresponding to the matching parameter with the highest matching degree can be determined to be the matched teaching video.
For example, the learner information may include a game name l_id, a learner level l_g, a character l_r, a current closing speed l_v=a length of time (seconds) taken by the current gate/(current gate game progress/gate total progress) ×current gate rated standard length of time (seconds)), an operation effective ratio l_p=an effective operand/an operation total number; accordingly, the presenter information may include a game name t_id, a presenter level t_g, a character t_r, an over-closing speed t_v=current gate video duration (seconds)/current gate rated standard duration (seconds), an operation effective ratio t_p=effective operand/operation total number.
It will be appreciated that the teaching video learned by the learner should be one generated by the same character as the learner operating the same game. According to the game names and game roles, teaching videos meeting requirements can be selected from the teaching video library, and therefore the number of the teaching videos matched is reduced. After the server acquires the learner information, the game name and the game role played by the learner can be determined according to the L_ID and the L_R, and the teaching video with the same T_ID and the same L_ID and the same T_R and the same L_R can be extracted from the teaching video library. The server is pre-stored with a corresponding matching algorithm, and for each teaching video, the server can calculate a plurality of difference parameters of learners and teachers, such as game level difference, current level difference and operation effective ratio difference, which are respectively |L_G-T_G|, |L_V-T_V|, and|L_P-T_P|. And respectively setting different weight coefficients for each difference parameter, multiplying each difference parameter by the corresponding weight coefficient, and accumulating to obtain the matching parameters of the teaching video and the learning video.
For example, for the differences of game level, current level progress and operational effective ratio, the weight coefficients may be 1, square and cube, and the matching parameters of the teaching video and the learning video are:
M＝|L_G-T_G|+|L_V-T_V|*|L_V-T_V|+|L_P–T_P|*|L_P–T_P|*|L_P–T_P|；
and respectively calculating the matching parameters M of each teaching video in all teaching videos with the same game name and game roles as those of the learning videos, wherein when the matching parameters M are minimum, the matching degree of the teaching video and the learning video is highest, and the teaching video is determined to be the teaching video matched with the learner information.
Further, the teaching video can be set to always follow the progress of the learner, and when the game scene of the learner is retracted, and the video progress of the learning video is retracted, the teaching video is correspondingly retracted to the playing progress matched with the video progress of the learning video. For example, the server may further generate a corresponding feature string according to the background areas of the teaching video and the learning video at preset intervals, determine whether the background areas of the teaching video and the learning video are matched, and when detecting that the background areas of the learning video and the background areas of the learning video are very different (i.e. fast forward, pause and rewind of the scene of the learner may occur), re-determine a new play start position of the teaching video according to new continuous frame images of the learning video, and then continuously determine a video adjustment amount according to an advance adjustment algorithm to adjust a play advance of the teaching video so as to realize scene linkage with the learner.
The learner can also break away from the game state of the current learning video by clicking the display area of the teaching video, and the teaching video is amplified and displayed and normally played. When the learner controls the teaching video to be reduced from the enlarged display state to the partial area display state, the teaching video can be played in a teaching mode again following the game progress of the learning video.
