Abstract

A method for automatically alerting, via an active noise reducing device having a sensor, a user to a predetermined or learned trigger in an external environment includes the steps of: (i) receiving, via the sensor while the active noise reducing device is in a first noise reduction mode, sensor data from the external environment; (ii) identifying, from the sensor data, the predetermined or learned trigger in the external environment; and (iii) automatically providing an alert to the user, in response to detection of the trigger, indicating the predetermined or learned trigger in the external environment, wherein the alert comprises entering a second operating mode of the active noise reducing device, the second operating mode characterized by providing hear-through of ambient sound in the external environment to the user.

First claim

What is claimed is:

1. A method for automatically alerting, via an active noise reducing device comprising a camera, a user to a nearby person in an external environment, the method comprising:
receiving, via the camera while the active noise reducing device is in a first operating mode in which the noise reducing device is reducing ambient noise from the external environment, image data from the external environment;
identifying, via facial recognition analysis performed on the image data, the nearby person in the external environment; and
automatically providing an alert to the user, in response to identifying the nearby person, wherein the alert comprises entering a second operating mode of the active noise reducing device, the second operating mode characterized by providing hear-through of ambient sound in the external environment to the user.

2. The method of claim 1 , wherein the camera is disposed on an external portion of the active noise reducing device.

3. The method of claim 1 , wherein the the nearby person is a specific person identified by the facial recognition analysis of the image data.

4. The method of claim 1 , wherein the alert further comprises a haptic or audio signal to the user.

5. The method of claim 1 , wherein the alert further comprises pausing or stopping a playback of audio via the device.

6. The method of claim 1 , wherein the alert further comprises lowering a volume of the device or amplifying a sound from the external environment.

7. The method of claim 1 , further comprising the step of indicating, via the device, that the alert has been provided to the user.

8. The method of claim 1 , wherein the identifying step is performed by an external computing device.

9. The method of claim 1 , wherein the providing step is performed via an external computing device.

10. The method of claim 1 , wherein the active noise reducing device comprises a sensor in addition to the camera, wherein the method further comprises:
receiving, via the sensor while the active noise reducing device is in the first operating mode, sensor data from the external environment;
identifying, from the sensor data, a predetermined trigger in the external environment; and
automatically, in response to the predetermined trigger, entering the second operating mode of the active noise reducing device.

11. The method of claim 10 , wherein the is an external microphone.

12. The method of claim 11 , wherein the predetermined trigger is a specific sound identified by the sensor data.

13. The method of claim 11 , wherein the predetermined trigger is a sound identified from the sensor data as coming from a particular location relative to the user.

14. The method of claim 10 , wherein the sensor is selected from the group consisting of: a LIDAR sensor, a radar sensor, a thermal sensor, and an ultrasonic sensor.

15. An active noise reducing device comprising:
an earpiece;
a microphone configured to obtain acoustic data from an external environment; and
a processor configured to: (i) receive, via the microphone while the active noise reducing device is in a first operating mode in which the noise reducing device is reducing ambient noise from the external environment, acoustic data from the external environment; (ii) identify, from the acoustic data, a directionality of an acoustic signal received from the external environment; and (iii) automatically provide an alert to a user of the active noise reducing device, in response to the directionality being determined as corresponding to a triggering direction with respect to the user, wherein the alert comprises entering a second operating mode of the active noise reducing device, the second operating mode characterized by providing hear-through of ambient sound in the external environment to the user.

16. The active noise reducing device of claim 15 , wherein the triggering direction is determined as coming from behind the user.

17. The active noise reducing device of claim 15 , wherein the microphone is disposed on an external portion of the active noise reducing device.

18. The active noise reducing device of claim 15 , wherein the active noise reducing device also includes at least one sensor selected from the group consisting of: a LIDAR sensor, a radar sensor, a thermal sensor, an ultrasonic sensor, and a camera.

19. The active noise reducing device of claim 15 , wherein the processor is also configured to automatically enter the second operating mode upon detection of a specific sound identified by the acoustic data.

20. The active noise reducing device of claim 15 , further comprising an indicator configured to indicate that the alert has been provided to the user.

21. An active noise reducing system comprising:
active noise reducing device comprising: (i) an earpiece; and (ii) a camera configured to obtain image data from an external environment while the active noise reducing device is in a first operating mode in which the active noise reducing device is reducing ambient noise from the external environment; and
a processing device configured to: (i) identify, via facial recognition analysis performed on the image data, the nearby person in the external environment; and (ii) direct the active noise reducing device to provide an alert to the user, in response to identifying the nearby person, wherein the alert comprises entering a second operating mode of the active noise reducing device, the second operating mode characterized by providing hear-through of ambient sound in the external environment to the user.
