My french book about locative media and location-based services (FYP Editions) has just been released. It's an overview of the field, that starts from the technical standpoint and go through various questions: what are they for, why the common scenarios (buddy-finder, spatial annotation, location-based coupons) have troubles being adopted, what to expect in the future as well as the space/time/social implications.

Update: my editor tells me that the rights to publish the books can be discussed with him (through contact (at) fypeditions (dot) com)
