About

The Worm is a real-time audience sentiment feedback tool for the classroom and other public speaking scenarios. It can be set up in a matter of seconds and track any sentiment the presenter can think of.

Anyone can create a profile and then set up a future presentation session. Once a presentation has been created, the presenter can send their audience a special code to join and vote. People with a code can enter it on the homepage, to access their voting page. They can vote as many times they want during a session. The presenter can then track the sentiment of their audience by viewing a live feed.

The Team

• Ethan "css is hard".
• Alex is a gitlord and Worm enthusiast.
• Karen is a Belgian kiwi aspiring code ninja who started coding in Basic on her dad's Commodore 128.

Technologies, frameworks and libraries used

Ruby, Rails, JavaScript, Chart.js, PostgreSQL, Heroku and a whole lot of Git.

Future enhancements

• uniquely identify voters on the server side for reporting purposes
• limit voting frequency per user (to be determined by presenter)
• prevent users voting from a region different from where the presentation is being held (option available to be used or not by presenter)
• show historical graphs and more detailed statistics on dashboard page
• improvements to voting algorithm to smooth chart

Lessons learned

• Github workflow when working in a team (and avoiding a lot of conflicts)
• using inbuilt Rails smarts (such as UUID, flash hash) and learning about its peculiarities (like how to add an image)
