Feeling sleepy but not sure if you actually need to sleep? The latest invention in high-tech eyewear can now monitor the fatigue level of its wearer based on eye movements among other factors. The eyeglasses are equipped with a technology that advises wearers if they are tired and concentration is already difficult.
The new invention is by JIN Co., the same firm that operates the JINS eyeglasses chain of stores. The glasses make use of sensors placed in the nose pads and bridge of the glasses, which detects eye movements. Movements are measured according to the differences in electric potential between the anterior and posterior parts of the eye, which are associated with brain activity. The results of the glasses’ analysis are transferable via wireless technology and wearers can check it on their laptops, smartphones and tablets. Aside from that, the glasses can also measure the level of drowsiness one person experiences, which is very useful for drivers on the road to avoid falling asleep on the wheel and causing accidents. Not only that, it is equipped with acceleration and angular velocity sensors to detect movements of the wearer’s head, enabling it to visualize body posture and compute calorie consumption as well as act as a pedometer that measure the wearer’s number of steps taken.
Both the Tohoku University and the Shibaura Institute of Technology collaborated to create the sensor used in the glasses. According to the Keio University engineering professor who teamed up with JIN for the system said, “Information concerning eye movements could promote an understanding of aspects of oneself that even the person does not know.” The glasses will be introduced to the retail market by next spring and price is yet to be determined.
