An ongoing issue with smartphones is that they pull people out of the world around them. Instead of interacting with others face-to-face or being aware of our surroundings, we increasingly spend our time tapping out tiny screens.

During Mobile World Congress, Sony announced a series of concept devices aimed at alleviating this issue. The idea is to keep us connected in a way that doesn't require staring down at a screen. Products include an earpierce, a clip-on camera, a projector, and a tiny robot. Only the first, the Xperia Ear, is coming out this year.
