Israeli designers Efrat Barit and Saar Shai have designed what may be the ultimate touchscreen smartphone accessory in the form of the Ringbow. The Ringbow is a tech-savvy ring designed to let you operate your smartphone from a distance.
The Ringbow has a directional nub with five different directional controls that can be customized. The Ringbow is not designed to replace the actual touch aspect of touchscreen cellphones, rather it is designed to make them easier to use by freeing up your other hand.
Unlike most concept devices, this one is actually being tested in the real world. Currently the gadget is only compatible with Android phones, but the designers plan on expanding it to all smartphone operating systems upon release. Looks like dirty smartphone screens could become a thing of the past.
