Samsung Gear VR requires certain Samsung phones.

This year's CES -- the giant trade show in Las Vegas during the first week of January that sets the agenda for the year in tech -- should be full of companies looking to hawk 360-degree video cameras (spherical cameras, as they're called). Others will try to cobble together software solutions. These are the beginning days of telepresence. It won't be hard, soon enough, for someone to stream their life in 360 degrees...and have you follow along live.
