The Immersion app works to map out your entire digital life with only your email. Created by a team at MIT Media Lab's Macro Connections, Immersion visualizes your life with your Gmail account. The app scans your email's metadata to build a map of your interactions. As a result, you can see an accurate graph of your online relationships complete with social circles and the strength of your interactions.
The app is able to recognize connections by looking at certain pieces of data. Immersion takes in each email's header, destinations, source and timestamp to get an accurate view of your life.
MIT Media Lab's web app was created as a tool for self-reflection. By visualizing your online life, the app allows you to see the relationships that you've built and how they're interconnected.
