Imagine controlling all digital devices with one small ring through a few gestures. A Japanese company Logbar Inc. has done just that; they have created a Smart Ring that will allow the wearer to control his smartwatch, smartphone, smarthome appliances and Google Glass, including other digital-enabled interactions.

Logbar.Inc dubbed the wearable device the "Ring." The tech company is located in Sunnyvale, California and has its base in Tokyo, Japan. The ring is worn on the index finger and it controls other devices with gestures made in the air. Simple tasks like taking a photo with a smartphone, playing music over a smartphone, even composing a tweet on a smart TV or checking the weather and many others can be done with the Ring. All these functions are accomplished through Bluetooth. The ring has to be within a five-meter range of the device needed to be controlled. There has to be no obstacles between the two devices for the Ring to function.

This ring can be set up easily and the wearer can have the freedom to control all his devices with just this one device. To use the ring the wearer has to create his own custom gestures for different functions. The device comes with an equipment to adjust the size of the zinc-coated ring and a battery stand that looks like a finger.

According to Digital Trends, the battery of the ring can last for one to three days with continuous use and for up to 18 days on standby. The device is powered by a lithium polymer battery the ones used in smartphone. According to Logbar, the device takes around three hours to fully charge.

The company raised $880,998 as a Kickstarter project, which was backed by 5,161 people. The Ring is available for purchase since Oct. 9. The device is priced at $269.99 and can be ordered on the Logbar website. Watch the YouTube Video of the "Ring" below.
