Abstract

Disclosed herein are embodiments of methods, in particular performed by at least one hearing device, uses of the method, hearing devices and hearing systems. The method can include determining a reference orientation and/or position, in particular a reference vector u ref , of a hearing device; detecting at least one movement and/or acceleration of the hearing device; determining at least one deviating orientation and/or position, in particular at least one deviation vector v d , of the hearing device based on the detected at least one movement and/or acceleration; and determining at least one deviation, in particular at least one deviation angle θ, between the reference orientation and/or position, in particular the reference vector u ref , and the at least one deviating orientation and/or position, in particular the at least one deviation vector v d .

First claim

The invention claimed is:

determining a reference orientation or position, reference vector u ref , of a hearing device; detecting at least one movement or acceleration of the hearing device; determining at least one deviating orientation or position, at least one deviation vector v d , of the hearing device based on the detected at least one movement and/or acceleration; and determining at least one deviation, at least one deviation angle θ, between the reference orientation or position, the reference vector u ref , and the at least one deviating orientation or position, the at least one deviation vector v d .

2 . Method according to claim 1 , wherein the hearing device comprises at least two input devices, and wherein the reference orientation or position, the reference vector u ref , is determined as the movement or acceleration, the movement or acceleration vector v acc , measured when the at least two input devices of the hearing device are located in a substantially horizontal plane H or in a plane deviating less than 25 degrees from the horizontal plane H.

3 . Method according to claim 1 , wherein the deviation angle θ is determined as the angle between the reference vector u ref and the deviation vector v d :

4 . Method according to claim 1 , wherein the deviation angle θ is separated in a left-right deviation angle θ xz and in an up-down deviation angle θ yz , and where the left-right and up-down deviation angles are determined as the angle between the reference vector u ref and their respective deviation vector v d;xz , v d;xz .

5 . Method according to any one of claim 1 , wherein a plurality of movements or accelerations of the hearing device are detected, and wherein an average tilt, an average tilt vector w avg , of the hearing device is determined based on the plurality of movements or accelerations.

6 . Method according to claim 5 , wherein the average tilt, the average tilt vector w avg , of the hearing device is determined at least partly based on a plurality of deviating orientations or positions, a plurality of deviation vectors v d , determined based on the detected plurality of movements or accelerations of the hearing device.

7 . Method according to claim 6 , wherein only deviations, deviation angles θ, or deviating orientations or positions, deviation vectors v d , below a threshold value are taken into account for determining the average tilt, the average tilt vector w avg .

8 . Method according to any one of claim 7 , wherein the threshold value depends on the direction in which the hearing device is moved or accelerated.

9 . Method according to claim 6 , wherein, when the detected movement or acceleration of the hearing device indicates a walking of the hearing device user for an amount of time larger than a threshold, deviations, deviation angles θ, deviating orientations, or positions, deviation vectors v d , are not taken into account for determining the average tilt, the average tilt vector w avg .

10 . Method according to claim 5 , wherein the average tilt, the average tilt vector w avg , of the hearing device is determined at least partly based on a plurality of deviations, a plurality of deviation angles θ, between the reference orientation or position, the reference vector u ref , and a plurality of deviating orientations or positions, a plurality of deviation vectors v d , determined based on the plurality of movements or accelerations of the hearing device.

11 . Method according to claim 10 , wherein only deviations, deviation angles θ, below at least 15 degrees are taken into account for determining the average tilt, the average tilt vector w avg .

12 . Method according to claim 5 , wherein the plurality of movements or accelerations of the hearing device are detected continuously.

13 . Method according to claim 5 , wherein the average tilt vector w avg (n) of a current sample n is determined recursively.
