London Eye to Become Giant Twitter Sentiment Meter

I’ve always thought one the most interesting landmarks in England was the London Eye. I would call it a ferris wheel, as I think most people from the US would, but it’s simply known as the Eye in the UK. A former British Olympic athlete named Daley Thompson has come up with a plan to help use the massive ferris wheel to promote the London Olympic Games kicking off soon.


Working with EDF Energy, the wheel’s sponsor, an algorithm will sort through positive and negative tweets sent with the tag #Energy2012. The wheel will be lit up depending on the portion of positive comments sent with the tag. The algorithm was designed by experts on sentiment analysis. For example, if 75% of the tweets are positive, 75% of the wheel will be lit. The more positivity, the more lights.

The wheel will also be lit up in various color patterns to celebrate major sporting moments of the day. If you want help control how much of the massive wheel is lit, you need to start tweeting when the games kick off. The last show will be held each night at 2100 BST that the Olympics are underway.
