This ring is the lord of them all. It’s something like the Sauron of rings. By putting it on, you can write anything you want in the air, and all the machines and humans around you will obey. Well, maybe not the humans. But you get the idea.
The ring’s magical powers are due to the combo of Bluetooth, a touch sensor, a few motion sensors, LED, vibration motor and a connection with iPhone. It’s the iPhone that actually reads all that air-writing and executes commands.
While the mechanism can seem a bit clunky and unintuitive (um, writing in the air?), this idea is pretty much aligned with where the gestural interactions and invisible technology are going. Check out the Ring’s Kickstarter here.
