COMPUTER APPARATUS AND METHOD IMPLEMENTING SOUND DETECTION AND RESPONSES THERETO
Sound detection and identification leads to responsiveness within an augmented reality environment. Information about an identified sound can be converted into a command for implementation by an augmented reality system, for display of a desired on-screen augmented reality effect.
1 . A computer system for implementing an augmented reality environment, the computer system comprising:
a sound acquirer for acquiring audio data;
a sound processor for recognizing a non-verbal sound event by processing the audio data using one or more sound models to obtain a non-verbal sound event identifier for the non-verbal sound event;
an augmented reality controller for determining and generating an augmented reality effect command by: inputting at least the non-verbal sound event identifier into an augmented reality effect command model; and receiving the augmented reality effect command from the augmented reality effect command model; and
an augmented reality environment generator for generating an augmented reality graphical data output by implementing the augmented reality effect command.
2 . A computer system in accordance with claim 1 wherein implementing the augmented reality effect command comprises overlaying a graphical symbol corresponding to the non-verbal sound event identifier over a portion of an image in the augmented reality environment.
3 . A computer system in accordance with claim 2 and further comprising an image localisation stage operable to identify a position of an object in the image and on the basis of which to place the overlay.
4 . A computer system in accordance with claim 1 and further implemented to establish a video telephonic session, the video telephonic session causing the generation of an image of a scene at one use point of the video telephonic session, and wherein the augmented reality controller is operable to generate an augmented reality effect in the image of the scene of the use point.
5 . A computer system in accordance with claim 1 wherein the sound processor is operable to determine a sound event identity on the basis of comparison with the one or more sound models.
6 . A computer system in accordance with claim 1 and further comprising a sound localisation processor for processing the audio data to obtain a sound event location identifier, corresponding to the non-verbal sound event identifier, indicating a direction of receipt of the acquired audio data.
7 . A computer system in accordance with claim 3 wherein the augmented reality environment generator is operable to generate an augmented reality graphical data output based on the a direction of receipt of the non verbal sound audio data.
8 . A computer system in accordance with claim 4 wherein the augmented reality environment generator is operable to generate an augmented reality graphical data output comprising an augmented reality effect in a position in the augmented reality environment based on a direction of receipt of the audio data.
9 . A computer system in accordance with claim 1 wherein the augmented reality controller is operable to determine an augmented reality effect with reference to one or more augmented reality effect models, the augmented reality effect being determined on the basis of comparison with the one or more augmented reality effect models.
10 . A computer system in accordance with claim 1 wherein the augmented reality effect command has a semantic correspondence with the non-verbal sound event identifier.
11 . A method of implementing an augmented reality environment, comprising:
acquiring audio data;
processing the audio data using one or more sound models to obtain a non-verbal sound event identifier for the non-verbal sound event;
determining and generating an augmented reality effect command by: inputting at least the non-verbal sound event identifier into an augmented reality effect command model; and receiving the augmented reality effect command from the augmented reality effect command model; and
generating an augmented reality graphical data output by implementing the augmented reality effect command.
12 . A non-transitory storage medium storing computer executable instructions which, when executed by a computer, cause the computer to perform a method in accordance with claim 11 .
13 . A computer system in accordance with claim 1 , wherein the augmented reality effect command model comprises a machine learned model.
14 . A computer system in accordance with claim 1 , wherein the sound acquirer is configured to acquire the audio data from a sound generation module.
15 . A computer system in accordance with claim 14 , wherein the computer system comprises the sound generation module and the sound generation module is configured to generate a sound for a virtual sound environment.
16 . A computer system in accordance with claim 1 , wherein the sound acquirer is configured to acquire the audio data from audio captured by a microphone.
