A computer interface that can supply answers to users without requiring them to dig their phones out of their pockets or tap away at a keyboard is being developed by Google.Amit Singhal, Google vice-president and senior search engineer, said that the company has been inspired by sci-fi series Star Trek to develop the “ubiquitous computing” concept, where gadgets woven into users daily lives seamlessly respond to questions.”Why should someone stop their conversation because theyre missing a tiny piece of information that you need to take that conversation further?” said Mr Singhal. “You have to pull out your phone. You have to unlock the phone. You have to type. Already you have lost valuable seconds and the conversation has become unnatural and awkward.”I would make a bold prediction that in the next three to five years you will have a Star Trek assistant, with a lot more capability than your phone has now. We have built baby steps of this already.”In future, answers to questions could be delivered to users through devices for the living room and kitchen appliances that respond to spoken commands.
