Check out a smart glasses that lets you control your phone by just scratching your nose
It’s no longer news that the world is fast becoming smarter as days go by. Some many devices are now available to control our phones, thus making it smarter. Such devices includes smartwatches, Google Glass, fitness bands and so on.

A device that appears to be behind others in terms of advancement is smartglasses and now that has change has come. A group of researchers has come up with a pair of prototype smart glasses, which allows you to control your smartphone or computer. All you need to do is rub your nose. With these smart glasses you can reject a call, pause a video, skip a song or carry out various other functions.
Unfortunately, these smart glasses are not available for sale now. This concept was created as an experiment by researchers from South Koreas KAIST University, Japans Keio University, Scotlands University of St. Andrews, and Georgia Tech University, USA.
These smart glasses work by way of electrooculography sensors, which are embedded in the bridge and nosepads of the frame. These sensors measure the electric potential of the surrounding flesh. Such sensors are usually used by doctors to record eye activity, and also as a way to recreate realistic eye movements in computer-generated imagery.
Now, when the wearer of these smart glasses touches them, the electric potential of the nose is changed. Researchers were able to identify the specific signatures of different motions, which include flicking and pushing the nose from one side to another. It has been said that this system can be used to minimize social awkwardness when using wearable computers. Indeed, Google Glass has a similar control system.
According to the researchers involved in the project, the main challenge in operating the smart glasses is getting the system to tell the difference between intentional and unintentional nose scratching. Certain gestures such as rubbing, are almost never falsely triggered.
Other gestures are more easily triggered, which makes it important for the system to be able to distinguish between intentional triggers and unintentional triggers.
