TAN (user technology assisted navigation) TV viewing interface as it is called, has a camera mounted on the TV which photographs the viewer and estimates the viewer’s degrees of interest, concentration, etc from circumstances such as who is watching the TV with how much interest. The information is processed by a tablet PC and recommended information is shown to the viewer, it is possible to show individual interests as well in case there are multiple viewers.

The viewer’s interest is determined by observing his face, facial expression and motion.

Maybe in the near future television will have a front facing camera and actually identify individual viewers by their faces and serve advertisements and give recommendation accordingly.

Maybe in the near future I won’t have a telescreen at all.

It’s important that we remember this.

The cylindrical robot is about 20 inches across. It houses a high-speed propeller system for propulsion, while four small wings allow it to move up and down and in every direction. The drone is equipped with high-power cameras and GPS tracking. It can fly for about 30 minutes at a time.

It appears that nearly everyone is thinking of or already has installed full body scanners. The differences is the type of scanner and whether it’s compulsory or not. Nearly all countries state that they are only doing this on flights to the United States.

The United States has also installed full body scanners at most of their major airports, though, under US law, everyone is supposed to have the option of a pat down as well.

Australia – body scanners will be introduced by early 2011
Belgium – waiting for EU decision
Canada – all airports to get scanners, in Vancouver, US bound passengers are to be targeted first, but have the option of a pat down; suspicious domestic or international travelers will be required to have a full body scan Winnipeg also offers the option of a pat down
China – hasn’t ruled them out, hasn’t decided whether to use them or not
France Charles de Gaulle airport – passengers may request a manual check
Germany – summer 2010 will begin testing
Ireland – seem to be still debating on whether they even want scanners, cost appears to be an issue; nothing noted on the Dublin airport website
Italy – all passengers traveling to the United States would be scanned.  I could not find if this is mandatory or not.
Japan – still deciding if they want them
The Netherlands – at Schiphol you can choose a body scan or pat down. You can download a pdf brochure from Schiphol outlining the details
Nigeria – will be installing them; From the tone of the article, I’d guess they’d be compulsory when it happens.
Russia – body scanners in use in Moscow since 2007, can request a pat down
South Africa – not considering full body scanners at this time
Spain – waiting for EU decision
United Kingdom – all airports mandatory or you do not fly
