I was just thinking that I ought to be able to raise my camera (iPhone) and ask a question like “where am I?”. GPS is never going to be perfect and signals bounce off buildings so what if you could combine GPS with a visual input to determine location? I can also imagine something basic like pointing my phone at a car and asking Google “What kind of car is that?”. Last but not least I can imagine pointing my phone at an insect bite and asking “Should I go see a doctor about this?”. That would be cool…like living in the future.
