Nokia Sensor is a program designed to run on Series 2.0+ phones. It may have a lot of buzz words - a social Bluetooth smartphone application, but it is an intriguing idea. You set up a personal homepage (dubbed a folio) and other Sensor users can read this (and you can read theirs). The folio includes your profile (pictures, motto etc.), a file sharing page (where you can put pictures, video and audio) and a Guestbook. The program works by scanning for other users over Bluetooth, which can be set to happen automatically in the background while the phone is on. Once connected you can read other's folio, leave them a message, and retieve their files.

There are some nifty feature such as Buddy Alerts (alerts you when someone you know is nearby), Group Codes (set in your folio to notify when someone with similar interests is around), Guestbook (where others can leave messages and comments) and a popularity measure (how many times your Folio has been viewed). Worth checking out even if it does take a while to find another Sensor user...

Clearly a certain number of users is needed before this sort of program really works. Mobiluck is a similar existing application and it's authors have built up a very large user base. The application also demonstrates that increasingly the smartphone is becoming increasingly sophisticated in its social awareness (easy to laugh at, but perhaps not so stupid when you think about the way the phone is always with you). With Series 60 phones becoming increaingly mass market (thanks to the 3230) its not hard to imagine this sort of thing having an impact. The idea of personal homepages exhcnaged over bluetooth with the ability to leave messages and share files (ringtones, wallpapers and camera pictures anyone) is bound to be very popular with younger phone users.
