ETH Life — Sometimes the diagnosis of episodes of illness in schizophrenia, rotatory vertigo, or reading and writing deficits needs electro-oculography (EOG), performed using a special medical apparatus. Andreas Bulling, a doctoral student at the Wearable Computing Lab of ETH Zurich, has developed spectacles that could in future make this technique portable.

The special spectacles fitted with additional sensors record the wearer’s eye movements. This recording is based on the principle of electro-oculography (EOG), a technique that has been known for more than 30 years and in which eye movements are measured using electrodes – similar to an electrocardiogram (ECG).
