Definitions
- Title Method and device for processing data in a virtual reality environment.
- the invention relates to the processing of augmented reality or mixed virtual reality data, intended to be displayed for example by a holographic display.
- virtual reality headsets or glasses making it possible to display a mixed virtual reality environment in the form of holograms which are integrated into the user's field of vision.
- the Microsoft® Hololens headset shown in Figure 1, offers such a display.
- Such a helmet is in particular equipped with sensors, for example cameras, allowing the user to interact with gestures in the virtual reality environment, in particular on virtual objects in the environment projected by the helmet or on commands. virtual objects associated with physical objects, i.e. mixed reality objects.
- Existing Hololens-type devices do not provide precise information to the user on the detection of the user's hand. For example, basic visual information is displayed to the user in the form of a dot placed in the center of the user's field of vision, indicating that a hand is detected and can therefore manipulate an object. The user has no information about which hand is detected (right, or left, or both), or where that hand is detected.
- Existing devices provide visual feedback on a screen relating to the detection of the user's hand.
- document US2012 / 0157203 proposes a game system in which the user's hand (or even both hands) is detected and displayed on a screen by means of a visual signal based on this detection.
- the representation of the detected hand takes the form of a corresponding hand (right or left respectively).
- the user no longer has any information on the position of his hand, nor on its detection.
- the visual representation of the hand provided to the user remains approximate as to its position in the virtual reality environment.
- the invention improves the state of the art. To this end, it relates to a method for processing data from a virtual reality environment.
- a method for processing data from a virtual reality environment comprises the detection of at least one part of the body of a user of the virtual reality environment, said part of the user's body being capable of interacting with at least one object of the reality environment. virtual reality, and the generation of at least one sound signal, the sound signal being a function of at least one characteristic relating to the at least one detected part of the body of the user of the virtual reality environment.
- the data processing method of a virtual reality environment thus makes it possible, following the detection of a part of the body of a user to generate a sound signal making it possible to inform the user of such detection. For example, when the part of the user's body corresponds to one of his hands, the information indicating to the user that his hand is detected is no longer dependent on the display field of the data of the virtual environment.
- the method according to the invention makes it possible to be able to detect part of the user's body even if this part of the body is no longer in the restitution space, even though it can still interact in the virtual reality environment.
- the method according to the invention thus makes it possible to overcome the drawbacks of the prior art in which the detection of a user's hand is only restored to the user by a visual signal.
- the sound signal is restored to the user as long as the at least one part of the body is detected.
- the acoustic signal is interrupted. The user is thus informed as soon as the part of the body is no longer detected by the system.
- the sound signal generated depends on the position of the part of the body detected with respect to an element of the virtual reality environment or with respect to another part of the body of the user detected.
- the sound signal depends on the distance between the part of the body detected and an object in the virtual reality environment.
- the signal sound is a function of the distance between a user's hand and an element, for example an object, displayed in the virtual reality environment.
- the sound signal depends on the distance between the part of the body detected and a real element restored in the virtual reality environment. For example, if the user is moving, the sound signal depends on the distance between the user and a physical obstacle in the environment.
- the sound signal depends on the distance between the part of the body detected and another part of the user's body, for example the user's head when the virtual reality system is implemented by means of of a holographic projection helmet.
- the frequency of the sound signal depends on the distance between the part of the body detected with respect to an element of the virtual reality environment or with respect to another part of the body of the user detected.
- the sound signal is thus more acute or more serious depending on the distance between the part of the body detected in relation to an element of the virtual reality environment or in relation to another part of the body of the user detected.
- the frequency is high when the part of the body detected is close to an element of the virtual reality environment and low when the part of the body detected is far away. element of the virtual reality environment, or vice versa.
- the frequency of the generated sound increases and when the detected body part moves away from the element, the frequency of the sound generated decreases.
- the generation of the sound signal depends on a left or right side of the part of the user's body detected.
- the part of the body detected is for example a hand
- the user is thus informed according to the type of sound signal or the rendering of the sound signal, if it is right or left hand.
- the generation of a sound signal as a function of the detection of the at least part of the body of a user of the virtual reality environment comprises the generation of a signal spatialized audio.
- the user in addition to the body part detection information, the user is informed of the location of the body part detected in the virtual reality environment.
- the sound signal is a binaural signal, the sound source of which is placed at the position at which the part of the user's body has been detected.
- the sound signal comprises two channels, one channel among the two channels being intended for the right ear, and another channel among the two channels being intended for the left ear, a channel or both channels of the sound signal being transmitted to the corresponding ear when the user's body part or another user's body part is detected on the side of the corresponding ear.
- the processing method further comprises the modification of the sound signal during an interaction of the part of the body detected with an element of the virtual reality environment.
- This particular embodiment of the invention makes it possible to limit interaction errors, for example by informing the user of the good or bad grip of a manipulable object of the virtual reality environment.
- the processing method further comprises the restitution of a visual signal representative of the detection of said part of the user's body in the virtual reality environment.
- the virtual reality environment is restored by holographic projection.
- the invention also relates to a device for processing data in a virtual reality environment configured to implement the processing method according to any one of the particular embodiments of the invention described above.
- a device comprises a processing unit comprising a processor and a memory operably coupled to the processing unit, the processing unit and the memory being configured for the implementation of the data processing method according to one any of the particular embodiments of the invention described above.
- such a device is included in a terminal.
- the invention also relates to a computer program comprising instructions for implementing the data processing method according to any one of the particular embodiments described above, when said program is executed by a processor.
- a program can use any programming language. he can be downloaded from a communications network and / or recorded on a computer readable medium.
- This program can use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other. desirable shape.

- an acoustic signal is generated during the detection by the system for implementing the virtual reality environment of a part of the body of the use likely to interact in the virtual reality environment (for example a hand, a foot .).
- a sound signal is a function of this detection.
- the sound signal in itself or its reproduction depend on the location of the part of the body detected in the environment, or else of the part of the body detected itself.
- FIG. 2 illustrates an example of an environment for implementing the invention according to a particular embodiment of the invention.
- the virtual reality environment is implemented by means of a helmet by holographic projection, for example the Hololens ⁇ helmet from Microsoft®.
- a user (21) is shown schematically wearing a holographic projection helmet (22).
- the holographic projection helmet (22) comprises a projection device (220) defining a projection space (23) and a detection device (221) defining a detection space (24).
- the projection device (220) comprises two screens (not shown) for holographic projection placed respectively in front of the user's right and left eye (21) of the helmet, as well as projectors (not shown) for projecting.
- a virtual reality environment for example a virtual object (25).
- Such a projection device thus defines a projection space (23) of the virtual reality environment, illustrated by dotted lines in FIG. 2.
- a projection space corresponds to a space in which the user (21) has the impression that virtual objects and the virtual reality environment are displayed.
- the projection space (23) is limited by the field of vision of the holographic projection helmet (22).
- the detection device (221) comprises for example a 2D camera and depth sensors (not shown), or else a 2D + depth camera.
- a part of the body of the user of the holographic projection helmet (22), for example a hand is in the detection space (24) (defined in solid lines in FIG. 2), this part of the body is detected by the detection device and can manipulate virtual objects projected in the virtual reality environment.
- the detection device and the projection device are coupled to a headset processing unit (22) (not shown) which is configured to process data from the virtual reality environment, ie 2D or 3D data from the scene to project by the projection device, and the data captured by the detection device, for example a part of the user's body to be detected and / or elements of the user's real environment.
- a headset processing unit (22) not shown
- data from the virtual reality environment ie 2D or 3D data from the scene to project by the projection device
- the data captured by the detection device for example a part of the user's body to be detected and / or elements of the user's real environment.
- the projection space (23) and the detection space (24) may be different.
- the detection space is wider than the projection space.
- FIG. 3 illustrates an example of an environment for implementing the invention according to another particular embodiment of the invention.
- the virtual reality environment is implemented by means of a processing unit (321) processing the data of the virtual reality environment, and communicating with a screen ( 320) used to display the virtual reality environment, and a detection device (31), for example a camera, for detecting interactions of the user (30) with the virtual reality environment displayed on the screen ( 320).

- a detection device for example a camera
- the detection device (31) defines a detection space (33) inside which a part of the user's body (30) can be detected to interact with the virtual reality environment rendered on the screen (320 ).
- the projection space of the virtual reality environment (defined by the screen 320) is completely distinct from the detection space, so that the user has no information that his hand, for example, is detected to interact with the virtual reality environment displayed on the screen (320). It is possible to display on the screen a visual representation indicating to the user that his hand is indeed detected in the detection space, for example as in document US2012 / 0157203.
- a visual representation offers only limited information to the user as to the position of his hand in the virtual reality environment.
- the projection space and the detection space are completely separate, so that it is not easy for the user to have a good perception of the position of his hand. relative to the objects of the virtual reality environment.
- FIG. 4 illustrates steps of the method for processing data in a virtual reality environment according to a particular embodiment of the invention. The process for processing data from the virtual reality environment is described here with the aid of the example described in relation to FIG. 2.
- Such a method comprises the detection of at least one part of the body of a user of the virtual reality environment, said part of the user's body being capable of interacting with at least one object of the reality environment. virtual reality, and the generation of at least one sound signal as a function of the detection of the at least part of the body of the user of the virtual reality environment.
- the sound signal is a function of at least one characteristic relating to the at least one detected part of the body of the user of the virtual reality environment
- the method can also be implemented according to the example described in relation to FIG. 3, or with any other system capable of implementing and rendering a virtual reality environment.
- a virtual reality environment is projected (E40) by a device for implementing a virtual reality environment, such as a holographic helmet, in a projection space.
- a virtual object (25) is projected into the projection space (23).
- the device for implementing a virtual reality environment then implements the detection (E41) in the detection space (24) of at least a part of the body of a user of the virtual reality environment .
- the part of the user's body to be detected is a part of the body capable of interacting with at least one object of the virtual reality environment. For example, it can be one hand, or both hands, one foot, or both feet. For simplicity, hereinafter, it is considered that this is a user's hand.
- the part of the user's body to be detected depends on the virtual reality application in which the method is implemented, and in particular on the possible interactions in the projected environment.
- hand tracking is performed as long as the hand is detected in the detection space (24) of the device.
- the 3D coordinates of the hand in the projection space are determined by the implementation device.
- At least one characteristic relating to this detection is then determined (E42). For example, it can be the detected position of the hand with respect to an element of the virtual reality environment or with respect to another part of the user's body detected, or the type of the part of the body detected (hand, foot, left hand, right hand, ).
- the determined characteristic corresponds to the 3D coordinates in the projection space of the part of the body detected.
- a distance is determined between the detected hand and the user.
- the location of the user in the projection space is determined as the origin of the reference frame of the projection space, corresponding to the user's head since the projection device is carried by the user.
- a distance is determined between the detected position of the hand and a particular virtual object projected into the projection space.
- the previous steps of detecting / tracking and determining a characteristic are implemented for each of the body parts detected.
- a sound signal is then generated (E43) according to the characteristic relating to the determined detection.
- the frequency of the sound signal is adapted as a function of the determined distance between the detected hand and the user or of the determined distance between the detected position of the hand and a particular projected virtual object. in the projection space. For example, the frequency of the sound signal is high when the hand approaches the user or the object. On the contrary, the frequency of the sound signal is low when the hand moves away from the user or the object.
- the sound signal is different depending on whether it is a left part of the user's body or a right part of the user's body that is detected.
- the user can differentiate whether it is his left hand which is detected or whether it is his right hand which is detected.
- two different sound signals and therefore differentiable by the user are generated.
- the generation of the sound signal depends on the position of the hand detected in the projection space.
- the generated sound signal is spatialized audio. The spatialization of the sound signal thus makes it possible to provide the user with information relating to the position of the detected hand.
- the spatialization of the sound can be done in a simple manner, in a stereophonic mode.
- the generated sound signal comprises two channels: a channel intended for the left ear and a channel intended for the right ear.
- the right or left channel of the sound signal is transmitted to the corresponding ear.
- the corresponding signals are transmitted through the same channel. If they are detected on different sides, the signals corresponding to the detected parts are transmitted on the channel corresponding to the side where they were detected.
- the spatialization of the sound signal is implemented by generating a binaural signal, the sound source of which is placed at the position at which the part of the user's body has been detected.
- FIG. 5 illustrates a visual representation of such a spatialization of the sound signal, in the case of a virtual reality environment implemented by a holographic helmet.
- FIG. 5 shows in a schematic top view, the user (21) equipped with a holographic helmet (22) projecting a virtual reality environment in the projection space (23).
- the detection space (24) of the projection device is also illustrated. According to the example illustrated in FIG.
- the user's hand (51) is detected in the detection space (24) but outside the projection space (23), so that the user does not see not his hand (51) when viewing the virtual reality environment via the holographic device (22).
- the user (21) when the binaural sound signal is restored, the user (21) has the impression that the sound comes from the location (50) corresponding to the location to which the hand has been. detected.
- the sound signal is reproduced (E44) as it is generated.
- the reproduction can be made via loudspeakers placed on the projection device or else placed in the physical environment of the user and in communication with the projection device.
- the sound signal is restored to the user as long as the hand is detected.
- the hand leaves (52) from the detection space (24) the restitution and the generation of the sound signal are interrupted.
- a visual signal indicating the detection of the part of the user's body can also be displayed (E44) to the user, in the projection space.
- This visual signal can be displayed at the detection location of the body part if it is detected in the projection space.
- the visual signal can be displayed in a space of the projection space reserved for displaying information such as a menu, interaction commands, etc.
- the visual signal can also be representative of information complementary to the detection of the part of the body. For example, it can indicate the side of the body part detected (left hand, right hand, a state of gripping an object, a detected state of opening / closing of the hand in the event that actions in the virtual reality environment are able to be controlled by a change of state of the hand, ).
- the sound signal when the user interacts (E45) with an object of the virtual reality environment, the sound signal is modified (E46) as a function of this interaction.
- the sound signal may change when the user grabs an object or opens a door.
- the sound signal can be modified differently depending on whether the interaction is correctly performed by the user. For example, when the user catches an object, for example by closing the thumb and forefinger according to the Hololens technique, if the closed state of the hand is detected, a new sound signal is generated and played back. This new sound signal is different from the signal generated during the detection of the hand without gripping an object. Thus, the user is informed of the good grip of the object. Likewise, when the user manipulates the object and a change in the state of the hand is detected, for example an opening of the thumb and index finger, the sound signal is again modified. The user is thus informed of the change, and can reposition his fingers correctly if the change of state detected by the system was not due to the user. Likewise, if the user opens his hand to release the object, but the sound signal is not modified, he is thus informed, by the absence of modification of the sound signal, that the change of state of his main has not been correctly taken into account by the system.
- This particular embodiment of the invention thus makes it possible to avoid handling errors during interactions in the virtual reality environment.
- FIG. 6 illustrates the simplified structure of a device DISP for processing data in a virtual reality environment according to a particular embodiment of the invention.
- a device is configured to implement the virtual reality data processing method according to any one of the embodiments described above.
- the device DISP comprises a memory MEM, a processing unit UT, equipped for example with a processor PROC, and controlled by the computer program PG stored in memory MEM.
- the computer program PG comprises instructions for implementing the steps of the data processing method as described above, when the program is executed by the processor PROC.
- the code instructions of the computer program PG are for example loaded into a RAM memory before being executed by the processor PROC.
- the processor PROC of the processing unit UT notably implements the data processing method according to any one of the embodiments described in relation to FIG. 4 according to the instructions of the computer program PG.
- the DISP device comprises a detection device CAPT configured to detect at least part of the body of a user in a detection space of the virtual reality environment.
- the DISP device also comprises a PROJ projection device making it possible to visually restore the virtual reality environment to the user, for example via a holographic projection technique or via a display on a 2D or 3D screen with glasses or without glasses.
