That it was public citizens or commercial uses

"This device help me perhaps to convince my neighbors they make too much noise in the building", launches Joséphine, while he attached around his wrist a bracelet black and thick. As other volunteers, she experimented with the Green Watch, an object can measure in real time the level of ozone and noise, and then send this information via a mobile phone in "Future in Seine". "From data collected by these bêtatesteurs, pollution maps carried out daily from May 30 to June 7, said Thierry Marcou, Director of the city led by the Foundation Internet 2.0 program generation (FING).". The objective is "to associate the urban environmental measurement, and thus the impression to participate in the protection of the environment".

Since a few weeks, the experimental move. Prototypes were tested by volunteers of the 2nd arrondissement of Paris, by researchers at the city of sciences and adolescents of the ecological club of the College Jean-Moulin de Montreuil. "It is of small samples, but we still found some unexpected results, explains Thierry Marcou." Our volunteers, for example, were very surprised to see higher rates of ozone in the pedestrianized streets.

Beyond the awareness of the environment, this Green Watch wants to contribute to the creation of new urban services, city dwellers would be co-producers. Its designers hope to see the emergence of other sensors, under the impetus of other actors. That it was public, citizens or commercial uses. Why not a sensor pollen or electromagnetic waves Already, the RATP would exploit this experiment to improve load distribution for travellers between the lines of Metro. "Our project is part of a process of open innovation, said Daniel Kaplan, General delegate of the FING." Data are available to anyone who wants to exploit them and undertakes to respect an ethical Charter.

Individual routes

Designed by the French publisher of video games Xylabs, the Watch includes a sensor of ozone, a sensor of decibels and a GPS chip. This box is the data and sends them via Bluetooth to a mobile phone that accompanies it. The phone displays a developed by SFR, Java application for viewing real-time ozone and noise levels. These measures are presented in the form of an eye the pupil color varies depending on the quality of the air and that of the iris with the noise. All these data are sent from the phone to an open platform called "Citypulse", designed by Altran Telecoms & Media. The end result is a map developed by the CiTu, an association of university laboratories, accessible via the Internet, which géolocalise pollution levels from the individual routes of carriers of the watch.

"And this watch, it will pay" launches Joséphine, pragmatic. Silence. And, for cause, the Green Watch is still based on any economic model. "The vocation of these drivers is to test the interest of the public concerned for new uses so that our partners can then develop a market in which we will be present," explains Nathalie Ricard Deffontaine, head of the pilot projects Center and citizens in SFR. For the operator, which lacks internal R & D centre, the innovation strategy through design and testing of various applications, in partnership with a start-up. For its part, Altran has draw the developments already achieved the project Green shows to offer new services to its customers. "It is also a question of image," says Thomas Bensoussan, consultant at Altran. These experiments are a reminder that we are innovative and committed partners in the protection of the environment.

Correctness of instrumentation

On this point, the network of monitoring the quality of air in Ile de France (Airparif) remains vigilant. "Having not been contacted by the Green Watch designers, we are not technically able to judge the relevance of the data", said Martine Boissavy, the communication service. Thus, the ozone sensor knows not yet make the distinction between interior and exterior. So far, Airparif, fitted in 2007 volunteers of portable pollution sensors, recognizes the interest of the project. "These itinerant sensors have the advantage to assess more closely the exposure to pollution of urban dwellers when travelling, what our fixed stations know not to do", said Martine Boissavy. On its side, the Observatory of the noise in the Ile-de-France, Bruitparif, proposed to put in place a Green Watch assessment protocol to evaluate the correctness of the instrumentation. And comparing the measurements with a sound level meter of reference, in the laboratory and in a situation. "The measures will gain scientific credibility, more green watch will be adopted," admits Thierry Marcou.
