Geoscientists at the University of Edinburgh have created an amazing portable device, the Edinburgh Augmented Reality System, (EARS) that uses GPS locators and a laptop computer to provide an audio guide customized to the exact location that the person in standing in. A tourist would be able to wander around Paris, for example, and hear detailed historical and architectural descriptions of whatever building he or she passes by. There is no need for the person to follow a prescribed, pre-set route. Because the system uses a GPS locator, the system will, if and when fully developed, be able to provide information that is accurate no matter where the person goes. The implications for this are frankly incredible. Imagine if the system could be enhanced to provide video input through 3D headsets that showed the input in a corner of the screen while preserving a clear picture of your view of the real world. You could wander around modern Paris and at the same time see what it looked like in 1904 or even what it may look like in 2104. If this 3D display is interactive, continuous and massively multiple, it would raise interesting issues about domicile - does the viewer "live" in the real world or the virtual one or both simultaneously? Domicile has implications for the freedom of speech issue because of the company town principle and the state action doctrine, as discussed in my recent paper in the Journal of Internet Law.
