Abstract: A method, in particular performed by at least one hearing device, a hearing device, a binaural hearing system, and a computer program are disclosed. The method can include detecting at least one motion signal of at least one hearing device, processing the at least one motion signal of the at least one hearing device in three individual channels representing three spatial dimensions x′, y′, z′ of the at least one hearing device, calibrating the orientation of the three spatial dimensions x′, y′, z′ of the at least one hearing device to a standardized orientation of the head of the user wearing the at least one hearing device, and determining the amount of motion of the at least one hearing device in at least one of the calibrated spatial dimensions x, y, z of the at least one hearing device.

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 (SBF1, SBF2), 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 (ΔPBF=SBF1−SBF2)—at least in a specific electrooculography mode of operation—represents an electrooculography signal (ΔPEOG) 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.

Abstract: A hearing system is adapted to be worn by a user and configured to capture sound in an environment of the user and comprises a) a sensor array comprising M transducers for providing M electric input signals representing said sound and having a known geometrical configuration relative to each other; b) a detector unit for detecting movements over time of the hearing system, and providing location data of said sensor array at different points in time t, t=1, . . . , N; c) a first processor for receiving said electric input signals and—in case said sound comprises sound from a localized sound source S—for extracting sensor array configuration specific data τij of said sensor array indicative of differences between a time of arrival of sound from said localized sound source S at said respective input transducers, at said different points in time t, t=1, . . . , N; and d) a second processor configured to estimate data indicative of a location of said localized sound source S relative to the user based on corresponding values of said location data and said sensor array configuration data at said different points in time t, t=1, . . . , N.
