BT's broadband applications research centre has developed a "futuristic wireless technology for the home", a kind of modern Teletext for broadband connected customers:
The idea is to bring users personalised online information in an easy, integrated and unobtrusive way, piping news and other information into home environments rather than having to go online. This brings us closer to natural interaction with computers by communicating in terms of colour, sound and speech.
Information, such as e-mails or weather reports, would manifest as ambient alerts on unobtrusive devices, using animated light patterns and sounds. Users can then wave their hand over the front of the device, prompting it to provide them with more detailed information using Laureate, BTs text-to-speech software, to read out the information highlights in a natural voice.
One experimental ambient interface has a fluid, oval design and clear front where the light sequences appear. It is intriguingly shaped and integrates easily into any environment, sitting neatly on a coffee table or kitchen worktop, for example. The design concept was to create an unobtrusive but always-on source of information that people will want in their homes.
Sounds very interesting, although its hard to build up a mental picture from the descriptions provided.
