Word-lens - real-time text-recognition. It’s a bit wobbly and underpowered at the moment, but this is state-of-the-art.
It gave me a daft idea: ANPR (Automatic Number Plate Recognition) using a smartphone on the dashboard of your car on a daily road commute. Eventually it’ll recognise your fellow commuters and where they share your journey. Could this help with lift-sharing?
