Dapper-Stream

The idea is to build smart online classrooms, with the ability to understand the emotions of the students while the class is going on, to understand their levels of comprehension of the course content

Inspiration

The idea stemmed from me being a student, who takes online classes and can rarely connect with the professor or the teacher on a level I do in real life classes. Taking in consideration how Minerva Schools (A complete college online with classes taken via video) hosts their classes, I tried to build a prototype of a similar product, where the professor can see real time response of their students, hence helping him/her to judge what ways to communicate work and what don't.

What it does

The app allows multiple students to join a class using a class ID (thanks to Agora.io !) and the professor can then click a button and judge the expressions of his/her students whenever they feel it is helpful to do so [button currently not working, as I couldn't figure out how to take a screenshot of the feed and send it to the backend, however, the multiple people joining and all their streams being displayed as a class still works]. This is particularly helpful when giving out assignments, suggesting something new and never-done-of-kind, and having long debates and discussions.

How I built it

Using the Agora Web SDK !

Challenges I ran into

oof, the whole app was built in under 6 hours (including coding, understanding the samples and documentation and testing), so I lost track of the challenges I had to face. That said, considering this is doable in such a small time-frame, it is definitely possible to build so much more into an app like this.

What I learned

How kick-ass Agora is ! It's really simple getting started with building in video feeds using their SDK, and using it for the first time was unexpectedly smooth.

What's next for Dapper-Stream

A lot !

first off, a better UI, login methods, and then comes the ability to run continuous emotion recognition on the frames to get a better and a seamless experience.

Additionally, considering Agora provides a chat API too, it should be fun integrating that into the app, to enable live communication via chat (as there should be in an online class).
