That’s the number of hours that people played solitaire around the world last year. Yikes.
One of the presenters from Carnegie Mellon has been doing work to try and tap into that manpower for tasks that humans do better than computers. By creating games that have meaningful output, suddenly those hours are being better spent, even though the people are still playing games and having fun.
So, next time you want to mix up your solitaire game playing (or if you need some new games for your toolbox), check out The ESP Game or Peekaboom. Not only did they seem fun, but they also are helping to categorize the images on the web in a meaningful way. Very cool.
