BT has developed a wireless technology for the home which notifies users of personalised news and information using ambient light sequences and sound alerts.

The user simply waves his or her hand across the device, which prompts it to read out the relevant details.

The technology was developed by BT's broadband applications research centre at Adastral Park and is expected to lead to new services for BT's broadband customers.

The aim is to bring users personalised online information in an easy way and without having to go online.

The device communicates using a wireless-based local area network connected to broadband Internet.

Users can choose which information the device monitors and customise how that information is displayed.

For example, information could include an alert when children are on their way home, notification of stocks and share prices or the status of bids on eBay. The device can also listen for key word commands such as'weather', and translate the request using speech recognition software before delivering the relevant information.

The use of voice, colour and sound has significant implications for people with sight or hearing impairments.

Adam Oliver, of BT Group, said: "This device really shows the benefits of having an'always-on' link to information.

"People who are older or disabled are often overlooked when creating new technologies but at BT we believe it is vitally important to design inclusively from the outset.

"The fact that you do not need keyboard skills or the ability to use complicated software to get information from the unit is fantastic."

Mr Oliver believes this is an example of what people really want: technology that works for them, rather than the other way around.
