Do you get sick of being surrounded by people yelling into their mobiles? It doesn't matter whether you're on the train, in the shops, in a posh restaurant - you are guaranteed to overhear some complete stranger discussing his latest break up in public. But there is hope! A Japanese engineer is developing a lip reading mobile phone, according to New Scientist this week. You simply mouth your words into the phone and a sensor picks up the tiny electrical signals from your facial muscles. The phone then works out what you're saying and converts it into a text message or email! No more yelling "I'M ON THE TRAIN!"
