We promised you the latest on the Fourth Generation [4G] phones last week, but we have been told we can?t write anything about them until we either a: set up our own multi-million pound research lab and absorb all the IP liability ourselves or b: just keep our mouths zipped until the official word is released. So, as we are short of a few million to blow on an over-pricing playground, we have instead found something equally as tasty, Trilateration.AT&T Labs, in Cambridge, United Kingdom, is working on a wireless technology under what they call their Sentient Computing Project that adds sensors to people and devices such as telephones and computers to, as they call it, “maintain a model of the world.“In a very scary Big Brother sort of way, this Tech allows you create a user ?profile? of all your communication needs which then ?follow you? where-ever you go. The phone nearest you become your phone with your calls routed to it. The computer nearest you are your computer with your data and your interface appearing on screen.The system uses an ultrasonic location system similar to triangulation of “position-finding by measurement of distances” but instead called the far superiorly sexy, Trilateration. There are transmitters in ceilings, sensors placed in devices and tags on your belt. It sounds far too like you were sentencing yourself to your own probation system to me. ?Hi, my name?s Mike I?m a digital prisoner of the night, have you seen my new Trilateration belt?? But hey, I?m sure they?re some freaks in the central America who are salivating at the thought of being able to track themselves from one state to the other.If you think we are telling porkies, then go to Cambridge and ask for Pete Steggles, Rupert Curwen or Rob Hague and politely tell them they need to get out more, or alternatively check out the site and mail them direct:http://www.uk.research.att.com/spirit/
