In this January 2015 file photo, attendees sit in the self-driving Mercedes-Benz F 015 concept car at the Mercedes-Benz booth at the International CES, in Las Vegas. Everything we buy or use these days has the potential to be smarter. Self-driving cars can transform our commuting hours into productive time. Sensor-laden socks can let us know how to jog with fewer injuries. The 2016 International CES will have a panoply of vendors showing off such connected devices, from smart umbrellas that will notify you if you've left them behind, to navigation devices that project directions on car windshields so you don't have to take your eyes off the road.
