Accenture's “Pocket Supercomputer” is in fact a phone behaving like a thin client. It can be used to send images and video of objects in real time to a server where they can be identified and linked to relevant information, which can then be sent back to the user.
The camera on the phone is used to take a video of an object — such as a book. According to the Accenture, the server software is smart enough to recognise the cover of the book — it's not yet able to read text — and can then, for example, return the price and history of the book, and details of where it can be bought.
By offloading the processing from a mobile device onto a server, there are few limits on the size and processing power available to be used for the storage and search of images.
