TWEB_Project1 is the source code and content for Dimmi application.
Dimmi's URL is https://dimmi-tweb.herokuapp.com and is built with AngularJS and MongoDB on Heroku.com
Note : You have the choice between discovering the application from the given URL, or running locally the project on your computer (see 4th chapter).
The content covers:
###1.1 What
This application allows the user to take part of a lecture, as the speaker (presenter) or as a memebr of the audience (viewer). The goal is to integrate a live feedback into a given lecture. The audience can send public requests during the "show", and the presenter is able to see them directly, and can change behavior according to it.
It is possible to find more details on DIMMI.md about the concept and the use.
###1.2 Why
We built this application in the context of a Web Technologies course (HEIG-VD). But the idea of the general concept comes from an established fact: the audience is often shy and hesitates to ask questions. This application aims to facilitate the communication and to assess the presenter if the audience has understood his/her speech.
As it is mentioned above, Dimmi is a web application, built with AngularJS and MongoDB on Heroku.com. Plus, this project uses PDF.js and Amazon S3 platform.
So, curious ? The very technical details are situated on DOCUMENTATION.md.
As we have first implemented the application locally, this version is the current one. As we mentioned, we offer a version built on heroku too. Unfortunately, we have the following problems for both versions :
- Lecture recovery : We propose to recover a past lecture, in order to continue a stopped one, or to see the stats (requests uses, questions). The problem is that it does not really work as we wish : the slide is not the one where we stopped, plus the number of the requests made by the audience.
- Archive : The section called "Archive" from the home page shows only the lectures made during the session, not all of them (since the creation of the account of the user). We have to correct that.
Be sure to have installed NodeJS, Bower and Grunt on your local machine.
-
Clone the repo.
-
Run MongoDB (mongod.exe file).
-
With another shell, at
TWEB_Project1root and write:grunt build. It will build the project. -
Run the project with
grunt serve. -
A new browser page will open at http://localhost:9000.
At this moment, we have stopped the implementation of this project. But we have planned to add some interesting additional features, in addition to correcting the problem discussed above (showing PDF) :
- Submit poll : It could be really useful for the presenter to create a specific poll about his/her lecture to the audience. Then, the answers would be saved, and possible to see in the archive.
- Notifications of questions : The implemented chat already allows the audience to express itself, but its issues have to be highlighted. Thus the presenter would see them better and could quickly answer to them.
- Duplication of presenter screen : We've imagined a second screen with only the PDF view for the beamer, and the initial one who allows the presenter to follow the mood of the audience.
- System monitoring : The admin have to monitor the application. We have to provide him a solution.
- Admin dashboard : It would be interesting for the admin to have an overview of the number of the visitors of the app, on which frequency, and so on. We have thought about adding the Google Analytics service.
We welcome fixes and improvements! If you have an idea on how to improve Dimmi, we'd love you to share it here. Please contact us if this is the case !
