I am experimenting with Nokia N95 for a project. One of the features we are looking at is how people use digitized information about time and space. N95 has integrated GPS system and 5 megapixel digital camera. With this, you can geotag every pictures you take and upload them on Flickr service.
And, you can see the map of the picture here. From these experiments, you can begin to see how digitized stream of information can powerfully transform the way we experience time and space collectively.
