296 Personal Content Experience: Managing Digital Life in the Mobile Age AARGHH! MY HAT! Phew, that was close. The police had already resorted to tear gas to disperse the riot, and rubber bullets were probably next. Bob had managed to duck and not get hit, but a painful stick blow landed on his back when the police came roaring through the street. Two of the armoured offi cers were running around with tasers. That was bad stuff. Bob was just barely able to escape by jumping over the fence to a parking lot. He landed hard and painfully, dropped his helmet on the concrete, one microphone broken, but the recording seemed to be still okay, so he just popped it back on his head. Not a good time now to review the footage. Bob needed to get an overview of the situation. Where’s everybody? He sent a tracking call to query the locations of his cell friends. Within a minute he had a map. Most everybody seemed be in the front line where the bus was burning, some people were nearby, Jessie on this very street and probably going to get the gas soon. Five members of the cell were missing, maybe indoors without data coverage. Hope so. Their last locations were near the warehouse that served as their makeshift headquarters. Bob decided to head that way to get replacement batteries for his helmet. A lot of juice would be needed to get this crazy night out to the world. In addition to tracking, there are alternative ways to support the social 12 aspects of location information. For instance, cellspotting is a web site that allows the users to fi nd information attached to their current location by other users, and also add their own content (annotations) for others to see, by using a client application installed in their mobile terminals. Should you be unable to fi nd any previously stored informa- tion of your current location, by adding your own content you become a “discoverer” of the location. As the name suggests, cellspotting uses location information obtained from the cellular network, also allowing tracking friends, and exchanging information with them. COMMENT: ABOUT CELLSPOTTING For many people, location information means navigation. It probably answers the security need of classic Maslow’s hierarchy, as many fear getting lost. For me the more interesting location questions are what I’m doing here and what’s around me? This is what makes cellspotting quite addictive. It’s fun to check whether someone has managed to spot the location or do I get the honour of naming the location. Compared to other popular location “games” like geocaching, cellspotting doesn’t require me 12 http://www.cellspotting.com/
