At the Consumer Electronics Show in Last Vegas, Intel unveiled Jarvis, an oddly shaped Bluetooth headset that wraps around the back of its wearer's ear. The earpiece communicates constantly with a companion Android app to remotely control the smartphone. Jarvis, which can understand voice commands and aptly supported by the Android app, performs all the functions you'd expect from a digital assistant – give directions, set appointments/reminders and look for restaurants among other things.
