Bill Gates, the chairman of Microsoft, talked on 6th January 2008 at International Consumer Electronics Show. He said “The first digital decade was largely driven by the keyboard and the mouse. Just in the last two years we’ve started to see the emergence of other modes of interaction. Touch on the Windows PC, touch on the iPhone, the Surface device that we’re talking about. We started to see speech, - the Tellme capability - built into the phone, the Ford Sync, where you get to talk and interact with your media or your phone capabilities.â€ÂÂ
