Mobile Phone As A Mirror Of The Society

«Че за модель?» на Яндекс.Фотках

What is a mobile phone useful for? To call your friends? To make a photo of such a squirrel?
No. To study your behaviour model and to use this knowledge for different aims.

To say you if there is one of your friends in the same zone in this or that time.
Or to catch you if you are a criminal.
To track your children (or maybe your husband or your wife).
Or to plan traffic in a city.
Or prevent outbreaks of disease.

All this is possible if scientists (or others) will track our movements monitoring calls and SMS's for 3 months and create the map of our everyday life. It's enough to add some/a sensor in your phone.
Because the studies demonstrated that

-Most people also move less than 10km on a regular basis
-humans wander in an apparently random fashion, similar to a so-called "Levy flight" pattern displayed by many foraging animals.
-The vast majority of people move around over a very short distance - around five to 10km
-people tend to return to the same few places over and over again
