There are several devices which we can use to control our phones. These include smartwatches, Google Glass, and so on. One device that has not caught up is smart glasses. But that has changed now; a group of researchers came up with a pair of prototype smart glasses, which let you control your smartphone or computer. Al 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 Korea’s KAIST University, Japan’s Keio University, Scotland’s 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.
