Dear Internet Traveller,

It is a pleasure for me to welcome you to the website of the 2nd edition of SomnoSafe, the short name of the "International Symposium on Somnolence, Vigilance, and Safety", a unique event fully focused on human vigilance and safety, and the link between them, where reductions and losses of vigilance may be due to a variety of causes, such as somnolence, drowsiness, sleepiness, "fatigue", and distraction. Of course, a major topic of interest is the monitoring of the level of vigilance of an operator, to take appropriate actions to prevent accidents, in particular in transportation.

The success of the 1st edition reinforced our conviction that "vigilance & safety" is a topic of significant interest worldwide, and worth having its own dedicated, international event. This success also motivated us to organize the present, 2nd edition!

While the 1st edition focused mainly on the loss of vigilance due to somnolence/drowsiness, we are broadening the scope of this and future editions to include any form of loss of human vigilance that may have an impact on safety. In that spirit, we might even - some day - rename the event VigiSafe.

"Vigilance & safety" is intrinsically multidisciplinary. It is indeed of interest, among others, to scientists studying the physiological basis of the variations in the level of vigilance, to engineers designing and building systems to quantify and monitor this level, to vehicle manufacturers installing such systems in their cars, airplanes, etc., to physicians dealing with sleep pathologies and the secondary effects of some medications, to policy-makers devising strategies to reduce the number of accidents due to reduced vigilance and, in particular, to drowsy driving. SomnoSafe allows all these folks with widely different backgrounds to interact closely and efficiently.

We work hard to make SomnoSafe "the place to be" for all professionals interested in "vigilance & safety", and we count on you to help us to reach this goal!

I invite you to take a look at the impressive roster of members of the Scientific committee, who help to keep the event at the highest level possible level of interest and quality.

If you are interested in setting up a specialized workshop on a topic within the scope of SomnoSafe, please contact me.
