A headworn, magnetic eyelid tracker could offer a new way to diagnose diseases.
The device, currently in the development stage, was created by Technion professor Levi Schachter and doctoral student Adi Hanukahas. The system relies on a pair of tiny magnets attached to the top of the eyelids, the motions of which are tracked via a set of standard, ophthalmologist refraction glasses. By analyzing the movements of the eyelids, different diseases can be detected—potentially including dementia and Parkinson’s disease.
Image Graphic: Blinking speed as a function of the amplitude of motion. Green – a patient with blepharospasm dystonia blinking at very high speed. Blue – after treatment, the same person blinking much more slowly.
