Control your smartphone with a ring-Ringbow
Designed by some Israeli guys, Efrat Barit and Saar Shai, the Ringbow may very well become the ultimate accessory for our smartphones. It definitely changes the way we can interact with touch-screens, hand-gestures recognition devices and augmented reality.
The Ringbow has a directional nub with five different controls for direction that can be personalized. By using his thumb, a user can easily guide the actions he takes on his phone, without having to physically touch it. This allows you to have more mobility. Hopefully, the Ringbow will become a device that will simplify our lives.
