Abstract
An electrooculography (EOG) signal capture system comprises a) a sensor array adapted for being located at one of a left or right ears of a user and/or for fully or partially being implanted in the head at left or right ears of a user, the sensor array comprising a number Ns of electric potential sensors, respectively, for sensing respective electric potentials from the user's head, where Ns is larger than or equal to two, b) electronic circuitry coupled to the sensor array and configured to provide at least two different beamformed signals (S, S), each being representative of a weighted combination of said electric potentials, or of signals derived therefrom, and wherein a difference between said at least two different beamformed signals (ΔP=S−S)—at least in a specific electrooculography mode of operation—represents an electrooculography signal (ΔP) from one or both eyes of said user. A single-sensor EOG-system is further proposed. The invention may e.g. be used in hearing aids or other electronic wearables.
