1. A hearing system comprising
a first hearing device configured to be worn at a first ear of a user, the first hearing device comprising a first displacement sensor configured to provide first displacement data indicative of a rotational displacement and/or a translational displacement of the first hearing device;
a second hearing device configured to be worn at a second ear of the user, the second hearing device comprising a second displacement sensor configured to provide second displacement data indicative of a rotational displacement and/or a translational displacement of the second hearing device; and
a processing unit communicatively coupled to the first displacement sensor and to the second displacement sensor,
characterized in that the processing unit is configured to
determine, based on the first displacement data and the second displacement data, a variation measure indicative of a variation of an orientation of the first hearing device relative to an orientation of the second hearing device and/or a variation of a position of the first hearing device relative to a position of the second hearing device; to
determine whether the variation measure matches a pattern characteristic for a manual gesture performed on the first hearing device and/or the second hearing device, the pattern defining a minimum amount of the variation and/or a temporal characteristic of the variation; and to
control an operation of the hearing system when the variation measure matches the pattern.
