Abstract
Embodiments are directed to sound source rendering in a virtual reality (VR) system that executes an immersive virtual environment including at least one virtual sound source. A motion sensor to produces a measurement of a motion of the user, and an imaging sensor is used to produce an indication of at least one physical feature of the user relevant to sound perception. A sound rendering engine determines and applies a head-related transfer function (HRTF) based on the at least one physical feature of the user, and effects a source direction of sound from the at least one virtual sound source according to a frame of reference of the user based on the motion of the user.
Claims25
A system for sound source rendering in a virtual reality (VR) system, the system comprising:
- a modeling engine to execute an immersive virtual environment (VE) that includes at least one virtual sound source;
- a motion assessor to read an output of a motion sensor to produce a measurement of a motion of the user during execution of the VE;
- a physical feature assessor to read an output of an imaging sensor and produce an indication of at least one physical feature of the user relevant to sound perception by the user, wherein the physical feature assessor is to read an output of an imaging sensor and produce an indication of at least one physical feature of the user during execution of the VE;
- a sound rendering engine to determine and apply a head-related transfer function (HRTF) based on the at least one physical feature of the user, and to effect a source direction of sound from the at least one virtual sound source according to a frame of reference of the user based on the motion of the user during execution of the VE;
- and
- a sound output device to produce a user-perceptible sound from the virtual sound source based on an output of the sound rendering engine during execution of the VE, the sound having directional properties based on the HRTF and source direction.
(canceled)
At least one non-transitory machine-readable storage medium comprising instructions that, when executed on a virtual reality (VR) system, cause the VR system to:
- execute an immersive virtual environment (VE) that includes at least one virtual sound source;
- read an output of a motion sensor to produce a measurement of a motion of the user during execution of the VE;
- read an output of an imaging sensor and produce an indication of at least one physical feature of the user relevant to sound perception by the user during execution of the VE;
- determine and apply a head-related transfer function (HRTF) based on the at least one physical feature of the user to effect a source direction of sound from the at least one virtual sound source according to a frame of reference of the user based on the motion of the user during execution of the VE;
- and
- produce a user-perceptible sound from the virtual sound source based on an output of the sound rendering engine during execution of the VE, the sound having directional properties based on the HRTF and source direction.
(canceled)
A method for sound source rendering in a virtual reality (VR) system, the method comprising:
- executing an immersive virtual environment (VE) that includes at least one virtual sound source;
- reading an output of a motion sensor to produce a measurement of a motion of the user during execution of the VE;
- reading an output of an imaging sensor and producing an indication of at least one physical feature of the user relevant to sound perception by the user during execution of the VE;
- determining and applying a head-related transfer function (HRTF) based on the at least one physical feature of the user to effect a source direction of sound from the at least one virtual sound source according to a frame of reference of the user based on the motion of the user during execution of the VE;
- and
- producing a user-perceptible sound from the virtual sound source based on an output of the sound rendering engine during execution of the VE, the sound having directional properties based on the HRTF and source direction.
