Abstract

A method for operating a hearing instrument worn in or on the ear and a hearing system having such a hearing instrument. In operation of the hearing instrument, an action of the hearing instrument or an external functional unit connected thereto can be triggered by a multiple, in particular double, finger tap on the hearing instrument. In a multiple tap test step, a multiple tap prompt to execute the multiple finger tap is output to the user. By way of a sensor integrated in the hearing instrument, in particular an acceleration sensor or a gyroscopic sensor, a measurement signal is detected which contains a signature of the executed multiple finger tap. The measurement signal is compared with a stored multiple tap pattern for the multiple finger tap. Feedback is output to the user as to whether the signature contained in the measurement signal corresponds to the multiple tap pattern.

First claim

The invention claimed is:

1 . A method for operating a hearing instrument worn in or on an ear of a user, the method comprising:
providing a hearing instrument that is configured for triggering an action of the hearing instrument or an external functional unit connected to the hearing instrument by way of a multiple finger tap on the hearing instrument; performing a multiple tap test step by:
outputting a multiple tap prompt to the user to execute the multiple finger tap;
detecting a measurement signal by a sensor integrated in the hearing instrument, the measurement signal containing a signature of the executed multiple finger tap;
comparing the measurement signal with a stored multiple tap pattern for the multiple finger tap; and
outputting feedback to the user as to whether the signature contained in the measurement signal corresponds to the multiple tap pattern.

2 . The method according to claim 1 , wherein the multiple tap pattern contains a threshold or a permitted range for:
a time interval between the pulses of the signature caused by the multiple finger tap; and an amplitude of the pulses of the signature caused by the multiple finger tap.

3 . The method according to claim 2 , which comprises, when the measurement signal does not correspond to the stored multiple tap pattern with respect to the time interval or the amplitude of the pulses, outputting the feedback to the user containing information about a deviation of the time interval or the amplitude from the respective stored threshold value or permitted range.

4 . The method according to claim 1 , wherein the sensor is an acceleration sensor or a gyroscopic sensor and the measurement signal reflects an acceleration or a rotational movement acting on the hearing instrument, and the comparing step comprises comparing only a predetermined directional component of the measured acceleration or rotational movement to the multiple tap pattern or wherein the multiple tap pattern contains a threshold value or permitted range for the direction of the acceleration pulses or rotational movement pulses caused by the multiple finger tap.

5 . The method according to claim 4 , which comprises, when the measurement signal does not correspond to the stored multiple tap pattern with respect to a direction of the acceleration pulses or rotational movement pulses, outputting the feedback to the user with information about the deviation of the direction from the respective stored threshold value or the permitted range.

6 . The method according to claim 4 , which comprises calculating a location of the multiple finger tap relative to the hearing instrument from the direction of the acceleration pulses or rotational movement pulses, and when the measured acceleration does not correspond to the stored multiple tap pattern with respect to the direction of the acceleration pulses, outputting the feedback to the user with information about the deviation of the location of the finger tap from a target position corresponding to the multiple tap pattern.

7 . The method according to claim 1 , wherein the action to be triggered by the multiple finger tap consists of accepting or ending a telephone call, and the method comprises outputting the multiple tap prompt in the form of a simulation of a telephone call in the multiple tap test.

8 . The method according to claim 1 , which comprises outputting to the user together with, or subsequently to, the multiple tap prompt, a rhythmic prompt sound to assist the user in an execution of the multiple finger tap by way of the hearing instrument, wherein a rhythm of the rhythmic prompt sound correlates with a timing sequence of individual expected single taps within the multiple tap pattern.

9 . The method according to claim 1 , which comprises, in addition to carrying out the multiple tap test step, carrying out a single tap test step by:
outputting to the user a single tap prompt to execute a single finger tap; detecting with the sensor that is integrated in the hearing instrument a measurement signal containing a signature of the executed single finger tap and comparing to a stored single tap pattern for the single finger tap; and outputting feedback to the user as to whether the signature contained in the measurement signal corresponds to the single tap pattern.

10 . The method according to claim 9 , wherein the single tap pattern corresponds to the multiple tap pattern with respect to an amplitude or a direction of a pulse of the measurement signal caused by the single finger tap.

11 . The method according to claim 1 , which comprises, in addition to carrying out the multiple tap test step, carrying out an instruction step by outputting to the user an instruction to carry out the multiple finger tap.

12 . The method according to claim 11 , wherein the instruction step comprises selecting the instruction to be output to the user from multiple different variants of the instruction depending on personal data on the user.

13 . The method according to claim 1 , which comprises carrying out one or more further auxiliary steps selected from the group consisting of:
a single tap test step that comprises:
outputting to the user a single tap prompt to execute a single finger tap;
detecting with the sensor that is integrated in the hearing instrument a measurement signal containing a signature of the executed single finger tap and comparing to a stored single tap pattern for the single finger tap; and
outputting feedback to the user as to whether the signature contained in the measurement signal corresponds to the single tap pattern,
an instruction step that comprises:
outputting to the user an instruction to carry out the multiple finger tap; and
a multiple execution of the multiple tap test step; and depending on at least one of
personal data on the user,
a preceding interaction of the user with the hearing instrument, or
at least one environmental condition,
making a selection about the type and number of the further auxiliary steps and a sequence of the multiple tap test step and the further auxiliary steps.

14 . The method according to claim 1 , which comprises varying a performance of the multiple tap test step in dependence on at least one of:
personal data on the user; a preceding interaction of the user with the hearing instrument, or at least one environmental condition.

15 . The method according to claim 1 , wherein the multiple finger tap is a double finger tap.

16 . A hearing system, comprising:
a hearing instrument to be worn in or on the ear of a user; said hearing instrument has a sensor configured to output a measurement signal which contains a signature of a multiple finger tap when the user executes a multiple finger tap on the hearing instrument; a finger tap recognition unit configured to recognize the multiple finger tap on the hearing instrument by comparing the measurement signal to a stored multiple tap pattern and, upon recognizing the multiple finger tap, to trigger an action of said hearing instrument or of an external functional unit connected to said hearing instrument; and a learning system configured to carry out the method according to claim 1 .
