BINAURAL HEARING SYSTEM FOR IDENTIFYING A MANUAL GESTURE, AND METHOD OF ITS OPERATION

The disclosure relates to a hearing system comprising a first hearing device (110, 160, 321, 341) and a second hearing device (120, 170, 331, 351) configured to be worn at a respective ear of a user, each hearing device comprising a displacement sensor (119, 129) configured to provide respective displacement data (211, 212) indicative of a rotational displacement and/or a translational displacement of the hearing device, and a processing unit (112, 122, 182, 210) communicatively coupled to the displacement sensors (119, 129). The disclosure further relates to a corresponding method of operating a hearing system, and a computer-readable medium storing instructions to perform the method.To allow identifying a manual gesture (411 - 418, 421 - 423, 431 - 434) performed on the first hearing device (110, 160, 321, 341) and/or the second hearing device (120, 170, 331, 351) in a reliable way, the processing unit (112, 122, 182, 210) is configured to determine a variation measure indicative of a variation of an orientation of the first hearing device (110, 160, 321, 341) relative to an orientation of the second hearing device (120, 170, 331, 351) and/or a variation of a position of the first hearing device (110, 160, 321, 341) relative to a position of the second hearing device (120, 170, 331, 351), to determine whether the variation measure matches a pattern characteristic for the manual gesture (411 -418, 421 - 423, 431 - 434), and to control an operation of the hearing system when the variation measure matches the pattern.
