The companies pitch their products

Tobii Technology's eye catching mouse trap

This eye tracking system allows people with limited use of their hands to move a cursor around a computer screen just by looking at it.

The inventors believe the system could potentially kill off the computer mouse as navigating with your eyes is far quicker than using our familiar furry friend.

Fraunhofer's face finder

The Fraunhofer Institute, whose past bright ideas include MP3, have now come up with a system that can find a face in any light and then tell you if the face is male or female, happy or sad, surprised or angry.

The inventors believe the system could be used for personalised advertising and more effective camera focusing.

Novonic's eBlocker

With concerns that radio waves from mobile phones might be harmful to our health, the company Novonic has come up with the e-blocker: a fabric that blocks radio waves.

It is being used in men's suits where it is been sown into the inside pockets to prevent radio waves penetrating the body.

Augmented Reality - where the virtual meets the real

Total Immersion has come up with a system that introduces digitally generated images into video of the real world in real time.

This is not superimposition. The virtual images actually interact with the real world video flow as if they are actually there.

The inventors believe Augmented Reality could be used in the cinema or even as an amusement - Grand Prix spectators could drive virtual cars around the race track while they wait for the real race to begin.
