I came across an interesting TED talk by Jonathan Harris. He talked about a few of the applications he has been working on.
One of those is We Feel Fine in which new blog posts are scanned every few hours to collect the feelings of the blogger. Each time someone says ‘I feel’ (or I’m feeling, I felt, …) the emotion is logged, next to the gender, age and location. This data is then used in some really pretty visualizations. Especially the photo’s attached to some of the ‘I feel’ sentences can be quite impressive. You can play around with it at their website.
The other application that really interested me is called Universe. The idea behind it is to draw / write the persons, events, etc on the virtual sky. It’s hard to describe it correctly, so you just have to watch the video below, or check out Jonathan Harris’ website.
