This past weekend I had the fortune of going to Austin, TX to visit with a friend from grad school. She works at IBM's design studio there so I got to tag along on some of the IBM sxsw events that were happening, without buying a badge. Aside from the great speakers and wonderful party, I was able to do some tourist-ing around the city in beautiful 70 degree weather.
I am an avid listener of podcasts, and on a recent episode of Radiolab, they were advertising a new "experiment" in interaction that they partnered with an app called Detour to produce. While in Austin, I downloaded it and gave it a shot. I didn't have high hopes, but it far exceeded my expectations.
The app leads you through a walking tour of the city while taking you along the mystery of the Servant Girl Annihilator, the first serial killer in history. The tour uses geolocation to know where you are and advance itself. There were a few bits that got wonky, but generally it was spot on. It also sets up relationships with people in different historical houses and museums so if you go in you can ask them about the artifacts relating to the story.
The most amazing part was at the end. It leads you up into a parking garage and as you look out across the city, you contemplate past and think about the future of crime and humanity. It sounds big and cryptic, but its true. If you ever go to Austin (or San Francisco, they have some tours for SF too), download the Detour app and use it. Its truly an experience.
