Abstract
A method of presenting an audio signal to a user of a mixed reality environment is disclosed. According to examples of the method, an audio event associated with the mixed reality environment is detected. The audio event is associated with a first audio signal. A location of the user with respect to the mixed reality environment is determined. An acoustic region associated with the location of the user is identified. A first acoustic parameter associated with the first acoustic region is determined. A transfer function is determined using the first acoustic parameter. The transfer function is applied to the first audio signal to produce a second audio signal, which is then presented to the user.
Claims20
A method of presenting sound to a user of a mixed reality environment, the method comprising:
- determining a first location with respect to the mixed reality environment;
- determining a first acoustic parameter associated with the first location;
- determining a second location with respect to the mixed reality environment;
- determining an acoustic relationship between the first location and the second location;
- determining, based on the first acoustic parameter and the acoustic relationship, a transfer function;
- detecting an audio event associated with the mixed reality environment, wherein the audio event is associated with a first audio signal;
- applying the transfer function to the first audio signal to produce a second audio signal;
- and
- presenting, to the user, a sound based on the second audio signal.
A wearable system comprising:
- one or more sensors;
- one or more speakers;
- and
- one or more processors configured to perform a method of presenting sound to a user of a mixed reality environment, the method comprising:
- determining a first location with respect to the mixed reality environment;
- determining a first acoustic parameter associated with the first location;
- determining, via the one or more sensors, a second location with respect to the mixed reality environment;
- determining an acoustic relationship between the first location and the second location;
- determining, based on the first acoustic parameter and the acoustic relationship, a transfer function;
- detecting an audio event associated with the mixed reality environment, wherein the audio event is associated with a first audio signal;
- applying the transfer function to the first audio signal to produce a second audio signal;
- and
- presenting, to the user, via the one or more speakers, a sound based on the second audio signal.
A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform a method of presenting sound to a user of a mixed reality environment, the method comprising:
- determining a first location with respect to the mixed reality environment;
- determining a first acoustic parameter associated with the first location;
- determining a second location with respect to the mixed reality environment;
- determining an acoustic relationship between the first location and the second location;
- determining, based on the first acoustic parameter and the acoustic relationship, a transfer function;
- detecting an audio event associated with the mixed reality environment, wherein the audio event is associated with a first audio signal;
- applying the transfer function to the first audio signal to produce a second audio signal;
- and
- presenting, to the user, a sound based on the second audio signal.
