Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1, the present invention provides a video interaction method, which includes the following steps:
step 1: a logical decision tree is established. According to the progress of the teaching content, an interaction link can be entered, in the link, a user can be guided to perform corresponding operations, such as answering according to questions appearing in the video, reading characters in the picture, selecting correct options in the picture, making corresponding body actions according to picture prompts and the like, and the interaction state of the user is collected by activating components such as a microphone and a camera, so that the corresponding video is positioned and played according to a logic decision tree. Through establishing the logic decision tree, the interaction behaviors which may occur to the user can be conveniently classified, and different classifications are positioned to corresponding video positions for playing, so that the interaction feeling of the user is improved.
Step 1.1: and judging the interaction state of the user in advance, and establishing a logic decision tree rule according to the interaction state of the user. The interaction state comprises: video output by a user, operational input, and real-time video pictures.
Step 1.2: and matching the corresponding video content according to the logic decision tree rule and the interaction state of the user.
Step 2: and recording and synthesizing the video according to the logic decision tree so as to meet the explanation requirement of the teaching video and different interaction states of corresponding users.
Step 2.1: and shooting and recording corresponding video and audio files according to the logic decision tree, and making corresponding pictures and animations.
Step 2.2: and sequencing the recorded and produced videos, audios, pictures and animations according to the logic decision tree and the teaching content, and combining the videos, audios, pictures and animations into a complete long video.
And step 3: and the user plays the video and enters an interaction link.
And 4, step 4: and collecting the audio and video of the user in the interaction link, and detecting and identifying the collected audio and video.
And 5: and skipping to the corresponding video clip for playing according to the detection and identification result.
Step 6: and after the feedback video of the interactive data is played, reading a subsequent video clip of the video playing content before interaction, and continuing a normal teaching flow.
And 7: and when the interaction condition is met, repeating the steps 4 to 6 until the course content is completed.
And establishing a logic decision tree rule including a time point, an identification judgment standard and the like according to an interaction state which is judged in advance and possibly occurs when the user interacts. And when the user plays the video and the interaction link is reached, acquiring the audio, the video and the input state of the user and identifying the interaction state of the user. In the interaction link, the user is guided to perform corresponding operations, such as answering according to questions appearing in the video, reading characters in the picture, selecting correct options in the picture, making corresponding body motions according to picture prompts and the like, and the interaction state of the user is collected by activating components such as a microphone, a camera and the like, so that the corresponding video is positioned and played according to the logic decision tree.
When the interactive link is voice question answering, a teacher of the teaching video puts forward a question to a user, after the user answers the question, the system collects the answer given by the user, and the answer is identified and classified to obtain correct answer, wrong answer, answer or other feedback results. And skipping to the corresponding interactive video clip and playing according to the identified feedback result, thereby interactively feeding back the answer of the user.
And when the interactive link is character follow-reading, displaying corresponding character segments through the picture, and prompting the user to follow-reading. Meanwhile, the system collects the audio of the user, identifies and judges whether the follow-up reading content is correct, whether the pronunciation is standard and the like, carries out corresponding classification, and skips to a corresponding interactive video clip for playing according to positioning, thereby carrying out corresponding interactive feedback on the follow-up reading condition of the user.
When the interactive link is a choice question, the user is guided to acquire user input information by clicking options appearing in the screen, answer conditions are obtained by recognition and classification, and the corresponding explanation videos are skipped to for playing, so that detailed explanation is provided for the options selected by the user.
