The present disclosure generally relates to sound processing for a synthesized reality setting, and in particular, to systems, methods, and devices for transforming a real sound into a virtual sound based on an acoustic reverberation property of a synthesized reality setting.
A physical setting refers to a world that individuals can sense and/or with which individuals can interact without assistance of electronic systems. Physical settings (e.g., a physical forest) include physical elements (e.g., physical trees, physical structures, and physical animals). Individuals can directly interact with and/or sense the physical setting, such as through touch, sight, smell, hearing, and taste.
In contrast, a synthesized reality (SR) setting refers to an entirely or partly computer-created setting that individuals can sense and/or with which individuals can interact via an electronic system. In SR, a subset of an individual's movements is monitored, and, responsive thereto, one or more attributes of one or more virtual objects in the SR setting is changed in a manner that conforms with one or more physical laws. For example, a SR system may detect an individual walking a few paces forward and, responsive thereto, adjust graphics and audio presented to the individual in a manner similar to how such scenery and sounds would change in a physical setting. Modifications to attribute(s) of virtual object(s) in a SR setting also may be made responsive to representations of movement (e.g., audio instructions).
An individual may interact with and/or sense a SR object using any one of his senses, including touch, smell, sight, taste, and sound. For example, an individual may interact with and/or sense aural objects that create a multi-dimensional (e.g., three dimensional) or spatial aural setting, and/or enable aural transparency. Multi-dimensional or spatial aural settings provide an individual with a perception of discrete aural sources in multi-dimensional space. Aural transparency selectively incorporates sounds from the physical setting, either with or without computer-created audio. In some SR settings, an individual may interact with and/or sense only aural objects.
One example of SR is virtual reality (VR). A VR setting refers to a simulated setting that is designed only to include computer-created sensory inputs for at least one of the senses. A VR setting includes multiple virtual objects with which an individual may interact and/or sense. An individual may interact and/or sense virtual objects in the VR setting through a simulation of a subset of the individual's actions within the computer-created setting, and/or through a simulation of the individual or his presence within the computer-created setting.
Another example of SR is mixed reality (MR). A MR setting refers to a simulated setting that is designed to integrate computer-created sensory inputs (e.g., virtual objects) with sensory inputs from the physical setting, or a representation thereof. On a reality spectrum, a mixed reality setting is between, and does not include, a VR setting at one end and an entirely physical setting at the other end.
In some MR settings, computer-created sensory inputs may adapt to changes in sensory inputs from the physical setting. Also, some electronic systems for presenting MR settings may monitor orientation and/or location with respect to the physical setting to enable interaction between virtual objects and real objects (which are physical elements from the physical setting or representations thereof). For example, a system may monitor movements so that a virtual plant appears stationery with respect to a physical building.
One example of mixed reality is augmented reality (AR). An AR setting refers to a simulated setting in which at least one virtual object is superimposed over a physical setting, or a representation thereof. For example, an electronic system may have an opaque display and at least one imaging sensor for capturing images or video of the physical setting, which are representations of the physical setting. The system combines the images or video with virtual objects, and displays the combination on the opaque display. An individual, using the system, views the physical setting indirectly via the images or video of the physical setting, and observes the virtual objects superimposed over the physical setting. When a system uses image sensor(s) to capture images of the physical setting, and presents the AR setting on the opaque display using those images, the displayed images are called a video pass-through. Alternatively, an electronic system for displaying an AR setting may have a transparent or semi-transparent display through which an individual may view the physical setting directly. The system may display virtual objects on the transparent or semi-transparent display, so that an individual, using the system, observes the virtual objects superimposed over the physical setting. In another example, a system may comprise a projection system that projects virtual objects into the physical setting. The virtual objects may be projected, for example, on a physical surface or as a holograph, so that an individual, using the system, observes the virtual objects superimposed over the physical setting.
An augmented reality setting also may refer to a simulated setting in which a representation of a physical setting is altered by computer-created sensory information. For example, a portion of a representation of a physical setting may be graphically altered (e.g., enlarged), such that the altered portion may still be representative of but not a faithfully-reproduced version of the originally captured image(s). As another example, in providing video pass-through, a system may alter at least one of the sensor images to impose a particular viewpoint different than the viewpoint captured by the image sensor(s). As an additional example, a representation of a physical setting may be altered by graphically obscuring or excluding portions thereof.
Another example of mixed reality is augmented virtuality (AV). An AV setting refers to a simulated setting in which a computer-created or virtual setting incorporates at least one sensory input from the physical setting. The sensory input(s) from the physical setting may be representations of at least one characteristic of the physical setting. For example, a virtual object may assume a color of a physical element captured by imaging sensor(s). In another example, a virtual object may exhibit characteristics consistent with actual weather conditions in the physical setting, as identified via imaging, weather-related sensors, and/or online weather data. In yet another example, an augmented reality forest may have virtual trees and structures, but the animals may have features that are accurately reproduced from images taken of physical animals.
Many electronic systems enable an individual to interact with and/or sense various SR settings. One example includes head mounted systems. A head mounted system may have an opaque display and speaker(s). Alternatively, a head mounted system may be designed to receive an external display (e.g., a smartphone). The head mounted system may have imaging sensor(s) and/or microphones for taking images/video and/or capturing audio of the physical setting, respectively. A head mounted system also may have a transparent or semi-transparent display. The transparent or semi-transparent display may incorporate a substrate through which light representative of images is directed to an individual's eyes. The display may incorporate LEDs, OLEDs, a digital light projector, a laser scanning light source, liquid crystal on silicon, or any combination of these technologies. The substrate through which the light is transmitted may be a light waveguide, optical combiner, optical reflector, holographic substrate, or any combination of these substrates. In one embodiment, the transparent or semi-transparent display may transition selectively between an opaque state and a transparent or semi-transparent state. In another example, the electronic system may be a projection-based system. A projection-based system may use retinal projection to project images onto an individual's retina. Alternatively, a projection system also may project virtual objects into a physical setting (e.g., onto a physical surface or as a holograph). Other examples of SR systems include heads up displays, automotive windshields with the ability to display graphics, windows with the ability to display graphics, lenses with the ability to display graphics, headphones or earphones, speaker arrangements, input mechanisms (e.g., controllers having or not having haptic feedback), tablets, smartphones, and desktop or laptop computers.
When a user wearing an SR headset makes sound (e.g., speaks, whistles, claps, etc.), the SR headset can either ignore the sound (allowing the user to hear the sound naturally) or record the sound and play it through integrated speakers. In either case, properties of the sound may not be consistent with those expected in an SR setting presented by the SR headset. Accordingly, it may be desirable for the SR headset to process the sound such that it sounds as though it was produced in the presented SR setting.
So that the present disclosure can be understood by those of ordinary skill in the art, a more detailed description may be had by reference to aspects of some illustrative implementations, some of which are shown in the accompanying drawings.
In accordance with common practice the various features illustrated in the drawings may not be drawn to scale. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may not depict all of the components of a given system, method or device. Finally, like reference numerals may be used to denote like features throughout the specification and figures.
Various implementations disclosed herein include devices, systems, and methods for sound processing for an SR setting. In various implementations, the method is performed at a head-mounted device located in a physical setting and including one or more processors, non-transitory memory, a microphone, a speaker, and a display. The method includes displaying, on the display, an image representation of the SR setting including a plurality of surfaces associated with an acoustic reverberation property of the SR setting. The method includes recording, via the microphone, a real sound produced in the physical setting. The method further comprises generating, using the one or more processors, a virtual sound by transforming the real sound based on the acoustic reverberation property of the SR setting. The method further comprises playing, via the speaker, the virtual sound.
In accordance with some implementations, a device includes one or more processors, a non-transitory memory, and one or more programs; the one or more programs are stored in the non-transitory memory and configured to be executed by the one or more processors. The one or more programs include instructions for performing or causing performance of any of the methods described herein. In accordance with some implementations, a non-transitory computer readable storage medium has stored therein instructions, which, when executed by one or more processors of a device, cause the device to perform or cause performance of any of the methods described herein. In accordance with some implementations, a device includes: one or more processors, a non-transitory memory, and means for performing or causing performance of any of the methods described herein.
Numerous details are described in order to provide a thorough understanding of the example implementations shown in the drawings. However, the drawings merely show some example aspects of the present disclosure and are therefore not to be considered limiting. Those of ordinary skill in the art will appreciate that other effective aspects and/or variants do not include all of the specific details described herein. Moreover, well-known systems, methods, components, devices, and circuits have not been described in exhaustive detail so as not to obscure more pertinent aspects of the example implementations described herein.
As noted above, when a user wearing an SR headset makes sound (e.g., speaks, whistles, claps, stomps, etc.) or another sound is produced in the physical setting of the user, the SR headset can either ignore the sound (allowing the user to hear the sound naturally) or record the sound and play it through integrated speakers. However, because audio has been found to be an important aspect of a fully immersive experience, it may be desirable for the SR headset to process the sound such that it sounds as though it was produced in the presented ST setting. As an example, a user may be in a physical setting of his or her living room and an SR setting of a concert hall. Sound made in the user's living room (e.g., speech produced by the user or another person) is recorded and played back with echo to make it sound as though the user spoke in the (synthesized) concert hall.

In some implementations, the HMD 120 is replaced with a handheld device (such as a smartphone or tablet) configured to present SR content in which the user does not wear the HMD 120, but holds the device with a display directed towards the field-of-view of the user and a camera directed towards the scene 105.

Although the data obtaining unit 242, the tracking unit 244, the coordination unit 246, and the data transmitting unit 248 are shown as residing on a single device (e.g., the controller 110), it should be understood that in other implementations, any combination of the data obtaining unit 242, the tracking unit 244, the coordination unit 246, and the data transmitting unit 248 may be located in separate computing devices.

In some implementations, the memory 320 includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid-state storage devices.

Although the data obtaining unit 342, the SR presenting unit 344, the sound processing unit 346, and the data transmitting unit 348 are shown as residing on a single device (e.g., the HMD 120), it should be understood that in other implementations, any combination of the data obtaining unit 342, the SR presenting unit 344, the sound processing unit 346, and the data transmitting unit 348 may be located in separate computing devices.
Moreover,
When a sound is produced in the physical setting 405, the sound travels to the ear of the first user along a number of paths, potentially reflecting off the surfaces 430A-430D. Accordingly, the physical setting 405 introduces an amount of reverb to the produced sound.
When a sound is produced in the physical setting 405, the physical setting 405 introduces an amount of reverb. However, this amount of reverb may be inconsistent with the amount of reverb that would be introduced by a real version of the first SR setting 505 (e.g., a cave). In particular, it may be expected that a cave would introduce a large amount of reverb, particularly as compared to the amount of reverb in a small indoor room. Accordingly, in various implementations, in order to produce a more immersive experience, the HMD records the real sound produced in the physical setting, generates a virtual sound by transforming the real sound to change (e.g., increase) the amount of reverb associated with the real sound, and plays the virtual sound to the first user. Put another way, as the first user speaks, his HMD picks up his voice, introduces reverberation consistent with what might be expected of the SR setting, and plays back his voice with the additional reverb in a speaker of the HMD (as well as the HMDs of other users who are participating in the same SR setting), thereby increasing the level of realism of the simulated reality experience.
As noted above, when a sound is produced in the physical setting 405, the physical setting 405 introduces an amount of reverb. However, this amount of reverb may be inconsistent with the amount of reverb that would be introduced by a real version of the second SR setting 605. In particular, it may be expected that a beach would introduce little to no reverb, particularly as compared to the amount of reverb in a large room without acoustic dampening (e.g., a large living room with wood floor, a cave, etc.). Accordingly, in various implementations, in order to produce a more immersive experience, the HMD records the real sound produced in the physical setting 405, generates a virtual sound by transforming the real sound to change (e.g., decrease) the amount of reverb associated with the real sound, and plays the virtual sound to the first user.
In particular, it is to be appreciated that real versions of the first SR setting 505 and the second SR setting 605 would be expected to introduce different amounts of reverb. In determining the amount of reverb that would be expected to be introduced by a real version of an SR setting, properties of the plurality of surfaces can be used, such as their locations (e.g., relative to each other or the location of the user), acoustic dampening characteristics, or other properties.
The method 700 begins, in block 710, with the device displaying, on the display, an image representation of an SR setting having a plurality of surfaces associated with an acoustic reverberation property of the SR setting. For example,
In various implementations, the acoustic reverberation property of the SR setting indicates an amount of reverb (e.g., a volume or a duration) that would be expected to be introduced by a real version of the SR setting. In various implementations, the acoustic reverberation property indicates an impulse response function (or transfer function) of the SR setting.
In various implementations, the plurality of surfaces are respectively located in the SR setting at a plurality of locations. Accordingly, the image representation of the SR setting includes image representations of the surfaces at the plurality of locations. In various implementations, the plurality of locations define the acoustic reverberation property of the SR setting. For example, when the plurality of surfaces are distant from a virtual location of the user, the acoustic reverberation property indicates a larger amount of reverb and when the plurality of surfaces are close to the virtual location of the user, the acoustic reverberation property indicates a smaller amount of reverb. As another example, when the plurality of surfaces are oriented to face the virtual location of the user, the acoustic reverberation property indicates a larger amount of reverb and when the plurality of surfaces are not oriented to face the virtual location of the user, the acoustic reverberation property indicates a smaller amount of reverb.
In various implementations, the plurality of surfaces are respectively associated with a plurality of acoustic dampening characteristics. In various implementations, the plurality of acoustic dampening characteristics define the acoustic reverberation property of the SR setting. For example, when the plurality of acoustic dampening characteristics are high (e.g., indicating a high degree of acoustic dampening), the acoustic reverberation property indicates a lower amount of reverb and when the plurality of acoustic dampening characteristics are low (e.g., indicating a low degree of acoustic dampening), the acoustic reverberation property indicates a higher amount of reverb.
As an example, the first SR setting (of which an image representation 505 is shown in
As another example, the second SR setting (of which an image representation 605 is shown in
The method 700 continues, at block 720, with the device recording, via the microphone, a real sound produced in the physical setting. In various implementations, the real sound is produced by the first user (e.g., by speaking or clapping). In various implementations, the real sound is produced by the second user (e.g., by speaking or stomping). In various implementations, the real sound is produced by other noise sources in the physical setting (e.g., a stereo system). In various implementations, the device transforms the (as described below with respect to block 730) differently depending on the source of the sound.
The method 700 continues, at block 730, with the device generating a virtual sound by transforming the real sound based on the acoustic reverberation property of the SR setting. In particular, in various implementations, the device transforms the real sound so that it sounds as though it were produced in a real version of the SR setting.
In various implementations, the device transforms the real sound based on the acoustic reverberation property by changing (e.g., increasing or decreasing) an amount of reverb of the real sound. In various implementations, this includes determining an amount of reverb of the real sound, determining an amount of reverb for the virtual sound, and changing the amount of reverb of the real sound to match the determined amount of reverb for the virtual sound.
In various implementations, the plurality of surfaces are respectively located in the SR setting at a plurality of locations, and transforming the real sound based on the acoustic reverberation property includes changing an amount of reverb of the real sound based on the plurality of locations. For example, in various implementations, changing the amount of reverb includes changing the amount of reverb to a first amount when the plurality of locations are distant from a virtual location of a user, or changing the amount of reverb to a second amount, less than the first amount, when the plurality of locations are close to the virtual location of the user.
In various implementations, the plurality of surfaces are respectively associated with a plurality of acoustic dampening characteristics, and transforming the real sound based on the acoustic reverberation property includes changing an amount of reverb of the real sound based on the plurality of acoustic dampening characteristics. For example, in various implementations, changing the amount of reverb includes changing the amount of reverb to a first amount when the plurality of acoustic dampening characteristics are low, or changing the amount of reverb to a second amount, less than the first amount, when the plurality of acoustic dampening characteristics are high.
In various implementations, the device classifies the SR setting into one of a plurality of discrete classes based on the plurality of surfaces (e.g., their location, acoustic dampening characteristics, and/or other properties). For example, the plurality of discrete classes can include a large room (associated with a high amount of reverb), a small room (associated with a small amount of reverb), or an outdoor location (associated with a small amount of reverb). As another example, the plurality of discrete classes can include an enclosed space having a smaller volume (e.g., a living room with a low ceiling) and an enclosed space having a larger volume (e.g., the same living room with a vaulted ceiling).
In various implementations, the device determines a transfer function based on the plurality of surfaces (e.g., their location and/or acoustic dampening characteristics). For example, the device can apply a ray-tracing algorithm to determine the transfer function. Thus, in various implementations, the device transforms the real sound by applying the transfer function to the real sound. In various implementations, the device further equalizes the real sound to compensate for the transfer function of the physical setting (e.g., using MMSE (minimum mean-squared error) or zero-forcing).
In various implementations, in addition to transforming the real sound based on the acoustic reverberation property of the SR setting, the device generates the virtual sound by further transforming the real sound based on one or more other acoustic properties of the SR setting. In various implementations, the device filters the real sound. For example, the device lowpass filters the real sound because the SR setting is underwater or highpass filters the real sound because the SR setting is in space. In various implementations, the device adjusts the frequency of real sound. For example, the device increases the frequency of the real sound (e.g., the voice of the second user) because the SR setting is a room full of helium. As noted above, in various implementations, the device transforms the real sound differently depending on the source of the sound. Accordingly, the device may adjust the frequency of the voice of the second user, but not ambient sounds. In various implementations, the device adjusts the volume of the real sound. For example, the device increases the volume of the sound because the SR setting is a rock concert or decreases the volume of the sound because the SR setting is a library.
The method 700 continues, at block 740, with the device playing, via the speaker, the virtual sound. In various implementations, playing the virtual sound further includes noise-cancelling the real sound. Thus, the user hears only the processed sound, rather than both the processed sound and the real sound.
In various implementations, the method 700 repeats in a different SR setting with a different transformation based on a different acoustic reverberation property of the different SR setting. Accordingly, in various implementations, the method 700 further includes displaying (as described with respect to block 710), on the display, an image representation of a second SR setting having a plurality of surfaces associated with a second acoustic reverberation property of the second SR setting different than the acoustic reverberation property of the SR setting; recording (as described with respect to block 720), via the microphone, a second real sound generated in the physical setting; generating (as described with respect to block 730) a second virtual sound by transforming the second real sound based on the second acoustic reverberation property of the second SR setting; and playing (as described with respect to block 740), via the speaker, the second virtual sound.
