‘Smart’ denim promises touchscreen tech clothes

People touch specially woven Project Jacquard fabric, in the hands of a small Google team called Advanced Technology and Projects (ATAP), to control lights or computer screens during a demonstration at Google's annual developers conference in San Francisco, California on May 29, 2015. Google announced that it is working with iconic US jean maker Levi Strauss to make clothing from specially woven fabric with touch-screen control capabilities.

A young man in a white T-shirt pulls on a dark blue denim trucker jacket, tucks his smartphone in an inside pocket and puts in-ear headphones in his right ear. 

He mounts a fixed-gear bike with flat, slightly curved wide handlebars. Riding through the streets of San Francisco, he occasionally taps or swipes his right hand over the left cuff of his jacket, as the directions he's listening to continually pop up on the screen of this advertisement.
