In our third and final round-up from Hannover's Cebit 2011 trade show you can find out more about the 3D displays that were on show.
We also have a report about the Tobii eye-controlled laptop which has a sensor that can see where you are looking on-screen and focus the computer's attention on that area.
Microsoft's German head Ralph Haupter gave a presentation at Microsoft's 'keynote' event at the Cebit trade show in Hannover on Monday.
His talk was largely about cloud computing - and he proved that speaking a different language is no barrier to business cliche when he described it as "ein game-changer" - but he also provided some interesting numbers on some of Microsoft's most recent products.
Most of them have already announced but we found it useful that they were all collected in one presentation, so here they are.
He started off by pointing out that the Xbox 360 had sold 50m units, a figure Microsoft CEO Steve Ballmer gave at his CES talk in January. The number of Xbox Live accounts is 30m, which is surprising. That includes both the paid-for Gold accounts and free Silver ones, which means that there are 20m Xbox 360s out there with effectively no internet connectivity (you need a Silver account to download games, demos and most other things).
More stats after the jump...
Microsoft and car maker Daimler have put together an app for the Windows Phone handset range that allows users to control the Daimler electric car.
The app, demonstrated in our video above, can show local maps overlaid with how far the car can travel based on how fully charged the battery is.
Note that the video is in German - the company's representative Frank Fischer was demonstrating it at the Cebit trade show in Hannover yesterday.
Vodafone was at the Cebit trade show demonstrating, among other things, a novel way to set up a cab office. The Vodafone pavilion has inside it a fully functioning taxi operating centre, which over the course of the show will be dispatching taxis around the city of Hannover.
