In Ericsson's future, you'll be able to transfer information between two gadgets by sending it directly through your body. The demonstrations of the technology are really cool, but what will it actually be good for in real life?
During today's Ericsson keynote at CES, the company's "capacitive coupling" tech was demoed as a way to easily transfer photos from a phone to a big screen. Usually, you'd use an HDMI cable or some kind of wireless conection to get this done, but in this case CEO Hans Vestberg used his hands as the connectors and his body as the cable. His colleague was holding a smartphone with a picture on it, and Vestberg touched it with one hand and a transmitter connected to the big screen with the other and poof, there was the photo.
This isn't anything we're going to be doing soon, but it's clearly a nice option for those times (or those regions) when there's no readily available network to help shepherd your files from A to B. And besides, the important thing about tech this cool is that it exists; we can figure out what to do with it later.
