I want to develop some new features. Example: 1) I can get audio stream, and I post it to ASR service go get text, and then I send to NLP service to understand user’s intention. In teacher’s screen I can search more content from website to extend more knowledge. 2) I can get video stream to extract user’s emotion or face. it use to find out who is absent or absent-minded in classroom.
