This is the code for the change blindness study website used for my Master's thesis at UNC Chapel Hill. It is a Ruby/Sinatra app.
- Ruby (Sinatra, Postgres, SQLite, & Datamapper gems)
- SQLite (for development locally)
- Postgres (for production)
- Rerun (optional for local development)
Install dependencies using Bundler via bundle install. A SQLite database file is used locally in development mode. A Postgres database is used in production mode. This code was intended to be deployed to an OpenShift environment, similar to UNC's CloudApps platform.
The entire application is in app.rb. Once all the dependencies are installed, the application can be run by using the shell script in the root of the project if you have rerun installed (./run.sh) or just running ruby app.rb.
There were 3 conditions being applied throughout a session: a 0.5-second delay between elements changing on screen ("blank-screen"), a normal HTTP request to a new page ("normal-http"), and an instant client-side only change ("no-http"). The conditions are in an array in app.rb that is used to ensure they are all equally applied--they're popped off the array one at a time at random.
