Meeting with Pierre:

There are three reasons for justify the mobility:
1. Physical experience while walking into the city which brings an added experience to the learning.
2. Finding special information on the site which cannot be simulated or incorporated in by any means. these information are not present on the maps of the city because too specialise to be part of a previous study.
3. Reporting virtual information from the virtual world into the physical world. For example, exploring the lost city is just one of these examples because it allows to follow a street that doesn’t exist any more with the physical experience of bumping into buildings.

One of the possible solutions is to use the specific information recorded from the physical position to solve something in the virtual and the obtained outcome to be the pointer to another physical position (next move).
