Wearable computing - a new generation

Very interesting idea at www.genoaconnections.org - The technology described appears to take a heads up camera or audio headset and allow a remote guide to provide a report on visual information that a blind user cant make sense of. The technology is intended to enhance the work done by a guidedog with more specific information on demand.
Its a really interesting idea and certainly adds a new dimension to options for wearable computing - most wearable systems integrate computer generated data with a real world view. This works by taking a real world view - transferring it to a sighted guide who then relays that imnformation back to the user.
The basic principles would be one sthat might interest other users, the idea of being able to remotely support a user with alzheimers who feels lost or disorientated by grabbing a camera view of surroundings and getting guidance from an aide could be quite valuable
You can of course take the concept still further, if we have mobnile phones that can extract data from an image and present it as text, (phots of lists, recipes etc) which can then be read by a screenreader - could we extend this further, integrating better GPS systems, or technology that recognises visual cues and gives feedback as a result. Such information could be relayed automatically through a heads up display - or could offer something simple into the display such as a magnification of fine detail that the user can't manage naturally.

It does pose some interesting concepts, where technology still further connects users to services, in this case on demand - but relies uponthat connection to deliver human intervention - plenty there to think about
