The VGo telepresence robot was a favorite of the booth. The robot acts as a proxy for someone who can't physically be somewhere, whether it be because of distance or a medical reason. It has a monitor to show the face of the person, as well as a camera and microphone so that person can see and hear everything VGo can. That person can control where the robot can go. VGo has been out with Wi-Fi for a year, but an LTE version was announced at the show.
Like something out of Star Trek, the Golden-I displays a small screen using a special visor. It's ideal for tapping into camera feeds or looking up diagnostic manuals while repairing cars or other gadgets. The device is voice controlled, so you're hands are free to do other things. The device is made by Kopin and Motorola Solutions.
