Look at this watch. Biggs sees it, and drools just a little; he drools a lot, though, so it might be unrelated. Known as “Vibering,” it’s a watch designed for the deaf and hard-of-hearing, and warns the wearer of incoming danger—an onrushing car, a reckless delivery guy on a bicycle, and so on.
Two rings go around the wearer’s wrist, and “listen,” so to speak, for any aforementioned danger. When it detects something, it sends a signal to the watch, which then vibrates, alerting the wearer that something’s up.
As a proponent of technology that actually does good in the world, I certainly wouldn’t mind seeing this move from pretty render to finished product.
