Stephen Wellman speaks about Google's mobile behaviour groups in Google Lays Out Its Mobile User Experience Strategy. Compare this with The problem with mobile social networks.

Understanding users, anywhere, anytime

Rechis said that Google breaks down mobile users into three behavior groups:

A. "Repetitive now"
B. "Bored now"
C. "Urgent now"

The "repetitive now" user is someone checking for the same piece of information over and over again, like checking the same stock quotes or weather. Google uses cookies to help cater to mobile users who check and recheck the same data points.

The "bored now" are users who have time on their hands. People on trains or waiting in airports or sitting in cafes. Mobile users in this behavior group look a lot more like casual Web surfers, but mobile phones don't offer the robust user input of a desktop, so the applications have to be tailored.

The "urgent now" is a request to find something specific fast, like the location of a bakery or directions to the airport. Since a lot of these questions are location-aware, Google tries to build location into the mobile versions of these queries.

PS: I just made a post with three QR Codes pointing to swiss services for the "Urgent Now".
