Abstract

An apparatus including circuitry configured to: enable a conversational service between a first user of the apparatus and a second user of a remote apparatus wherein the conversational service is a duplex service including simultaneous voice communication from the first user to the second user and voice communication from the second user to the first user; and enable synchronization of a switch to using an active noise cancellation mode at the apparatus for the conversational service and at the remote apparatus for the conversational service, wherein the switch to using the noise cancellation mode is synchronized between the first and second users.

First claim

The invention claimed is:

1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
enable a conversational service between a first user of the apparatus and a second user of a remote apparatus, wherein the conversational service is a duplex service comprising simultaneous voice communication from the first user to the second user and voice communication from the second user to the first user; and
enable synchronization of a switch to using an active noise cancellation mode at the apparatus and at the remote apparatus, wherein the switch to using the active noise cancellation mode is synchronized between the first and second users,
wherein the instructions, when executed with the at least one processor, cause the apparatus to enable synchronization of the switch between using a pass-through mode to using the active noise cancellation mode at the apparatus and at the remote apparatus, and
wherein the switch between using the pass-through mode to using the active noise cancellation mode is synchronized between the first and second users.

2. An apparatus as claimed in claim 1 wherein the conversational service is a phone call, a teleconference, a videoconference, a shared multimedia experience, a shared gaming experience or a shared virtual reality experience.

3. An apparatus as claimed in claim 1 , configured such that exterior local sound to the first user that is cancelled for the first user in the active noise cancellation mode is not cancelled for the first user in the pass-through mode.

4. An apparatus as claimed in claim 1 , wherein in the pass-through mode, pass-through sound rendered to the first user depends on a point of view of the first user.

5. An apparatus as claimed in claim 1 , configured such that the exterior local sound to the second user that is cancelled or is not provided for the first user in the active noise cancellation mode is not cancelled or is provided for the first user in the pass-through mode.

6. An apparatus as claimed in claim 1 , wherein in the pass-through mode, pass-through sound rendered to the first user depends on a point of view of the second user.

7. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to a switch to using the active noise cancellation mode at the apparatus and at the remote apparatus when the first user and the second user are focusing at a common point of interest.

8. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to switch to using the active noise cancellation mode at the apparatus and at the remote apparatus in dependence upon information about what visual content each of the first user and the second user is looking at.

9. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to increase a level of active noise cancellation at the apparatus and at the remote apparatus while a focus of a gaze of the first user and a focus of a gaze of the second user are converging and to decrease a level of active noise cancellation at the apparatus and at the remote apparatus while a focus of a gaze of the first user and a focus of a gaze of the second user are diverging.

10. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to switch from not using an active noise cancellation mode for the cancellation service to using an active noise cancellation mode at the apparatus and at the remote apparatus when:
there is a change from the first user looking at a first object and the second user not looking at the first object to the first user looking at the first object and the second user looking at the first object, or
there is a change from the first user not looking at a first object and the second user looking at the first object to the first user looking at the first object and the second user looking at the first object.

11. An apparatus as claimed in claim 1 , wherein the instructions, when executed with the at least one processor, cause the apparatus to enable synchronization of a switch from using the active noise cancellation mode at the apparatus and at the remote apparatus, wherein the switch from using the noise cancellation mode is synchronized between the first and second users.

12. An apparatus as claimed in claim 1 , configured as a headset.

13. A non-transitory program storage device readable by an apparatus, tangibly embodying a computer program that, when run on one or more processors, causes:
enabling a conversational service between a first user of the apparatus and a second user of a remote apparatus wherein the conversational service is a duplex service comprising simultaneous voice communication from the first user to the second user and voice communication from the second user to the first user; and
enabling synchronization of a switch to using an active noise cancellation mode at the apparatus and at the remote apparatus, wherein the switch to using the noise cancellation mode is synchronized between the first and second users,
wherein the instructions, when executed with the at least one processor, cause the apparatus to enable synchronization of the switch between using a pass-through mode to using the active noise cancellation mode at the apparatus and at the remote apparatus, and
wherein the switch between using the pass-through mode to using the active noise cancellation mode is synchronized between the first and second users.

14. A method comprising:
enabling a conversational service between a first user of the apparatus and a second user of a remote apparatus wherein the conversational service is a duplex service comprising simultaneous voice communication from the first user to the second user and voice communication from the second user to the first user; and
enabling synchronization of a switch to using an active noise cancellation mode at the apparatus and at the remote apparatus, wherein the switch to using the noise cancellation mode is synchronized between the first and second users,
wherein the instructions, when executed with the at least one processor, cause the apparatus to enable synchronization of the switch between using a pass-through mode to using the active noise cancellation mode at the apparatus and at the remote apparatus, and
wherein the switch between using the pass-through mode to using the active noise cancellation mode is synchronized between the first and second users.
