The German Research Centre for Artificial Intelligence was one of a growing group of exhibitors at this year's CeBIT showing how computer systems and AI are being integrated into our homes and everyday lives.

One system, which appeared at first glance to be just an ordinary wine rack, turned out to be an 'expert' sommelier.

Remove a bottle and detailed information on the wine's origin and taste appears on the rack's monitor. The 'virtual sommelier' also gives the current temperature of the wine, indicates whether it needs chilling and recommends decanting if necessary.

When eggs are removed from a refrigerator, for example, their best-before date can be indicated on a display.

There is also help with cooking from electronic kitchen appliances which can offer a range of options deduced from the ingredients. The system automatically suggests a range of relevant recipes and plays a video of the chosen recipe.

This information is made possible by RFID chips and sensors located on the items that transmit the information they contain to the system hidden in the appliance.

Similarly, the DAI Laboratory at the Technical University of Berlin is presenting intelligent services for the home environment.

The package includes the Smart Telephony System, which runs the caller's voice through the stereo system and puts his or her picture up on the television screen, while the call recipient can talk through a room microphone.

The Smart Home Energy Manager governs the intelligent use of light, heating and kitchen appliances, including monitoring energy consumption.

This allows families to be as energy efficient possible, thereby cutting energy bills and reducing environmental impact.
