Artificial intelligence is set to revolutionise tourism, on all scales -- robotic doormen at hotel entrances, rooms that customise themselves depending on the occupant tastes, virtual visits of touristic sites before going there in real conditions -- despite some impediments. Let's deal with this ongoing revolution! This is mostly how our brain works when we take an umbrella before leaving home as the sky is covered in large grey clouds. The most spectacular application of artificial intelligence is obviously robotics. We imagine even more easily what it could lead to, as we are nourished by'Star Wars', or at least what it already does in the hotel industry -- a robot-doorman to welcome us right after we get out of the cab, catch our luggage and guide us to our room inquiring about our travel vagaries and our schedule for the upcoming days.

In 2000, the Massachusetts Institute of Technology launched an ambitious project to transform the way the world uses computers. The new: computers as pervasive and invisible as the air we breathe. They called it Project Oxygen. For an overview of the Project's goals, and a Q&A with its founders, see "Project Oxygen's New Wind". Now, nearly two years out, the first technologies are rolling out of the labs.
