I can't stand people yammering away on trains and always make a beeline for the quiet carriage. But how would I escape if the train itself does the talking?
A company in Germany recently tested 'talking' train windows. They exploit the same technology used in some hearing aids to transmit sound directly to your skull.
Besides ads, they say the windows could be used to broadcast music, transport updates and weather reports. I say, hah! I bet the ads will vastly outnumber any useful bits of information.
