When Ericsson CEO Hans Vestberg used his Consumer Electronics Show keynote to demonstrate the company's Connected Me concept, which turns the human body into a bridge between gadgets, he was met with lackluster applause. Part of the problem was the audience didn't fully grasp what Vestberg was trying to show. He was on stage holding a smartphone in one hand and the sensor for an audio system in the other. The data signal shot through his body, playing an MP3 from the phone on the speaker system. In effect, he became a replacement for a USB cord or Bluetooth connection. People watching the presentation, however, were underwhelmed. The company showed it off at its giant booth at Mobile World Congress, and again this week at the Wireless show, where it largely went unnoticed.
