The present invention relates generally to virtual reality and augmented reality systems, and more particularly to preventing transition shocks (e.g., disorientation, nauseousness, motion sickness) during transitions between realities (e.g., transitioning between virtual reality and augmented reality environments).
Virtual reality (VR) is a computer technology that uses virtual reality headsets or multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to “look around” the artificial world, and with high quality VR move around in it and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens.
Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are “augmented” by computer-generated perceptual information, ideally across multiple sensory modalities, including visual, auditory, haptic, somatosensory, and olfactory. The overlaid sensory information can be constructive (i.e., additive to the natural environment) or destructive (i.e., masking of the natural environment) and is spatial registered with the physical world such that it is perceived as an immersive aspect of the real world environment (also referred to herein as the “real reality”). In this way, augmented reality alters one's current perception of a real world environment, whereas, virtual reality replaces the real world environment with a simulated one.
Currently, when a user transitions between different realities, such as between the virtual reality and the augmented reality environments or between the virtual reality and the real reality environments, the user may experience disorientation, motion sickness and/or nauseousness thereby degrading the user's experience.
In one embodiment of the present invention, a computer-implemented method for transitioning between different realities comprises developing a statistical model for predicting transitions between different realities when a user performs various actions. The method further comprises monitoring actions of a user. The method additionally comprises determining whether a probability of the user transitioning between a first reality environment and a second reality environment exceeds a first threshold value based on the monitored actions of the user and the statistical model. Furthermore, the method comprises ascertaining whether a probability of a transition shock event occurring exceeds a second threshold value as the user transitions between the first and second reality environments in response to the probability of the user transitioning between the first and second reality environments exceeding the first threshold value, where the transition shock event is an occurrence of adverse symptoms experienced by the user as the user transitions between the first and second reality environments. Additionally, the method comprises modifying a distance of an object from a reference point in one or more of the first reality environment and the second reality environment in response to ascertaining that the probability of the transition shock event occurring exceeds the second threshold value.
Other forms of the embodiment of the method described above are in a system and in a computer program product.
The foregoing has outlined rather generally the features and technical advantages of one or more embodiments of the present invention in order that the detailed description of the present invention that follows may be better understood. Additional features and advantages of the present invention will be described hereinafter which may form the subject of the claims of the present invention.
A better understanding of the present invention can be obtained when the following detailed description is considered in conjunction with the following drawings, in which:
The present invention comprises a method, system and computer program product for transitioning between different realities. In one embodiment of the present invention, the distance of objects from a reference point in the first and second reality environments is determined. For example, the distance of the object's location in the first reality environment from a reference point (e.g., camera system) as well as the distance of the object's location in the second reality environment from the reference point is determined. A determination is made as to whether the likelihood of a transition shock event occurring as a user transitions between the first and second reality environments exceeds a threshold value. A “transition shock event,” as used herein, refers to the occurrence of adverse symptoms, such as disorientation, nauseousness or motion sickness, experienced by the user when the user transitions between different realties. In response to the likelihood of the transition shock event occurring exceeding the threshold value, the distance of the object from the reference point in the first and/or second reality environments is modified so as to prevent users from experiencing transition shocks (e.g., disorientation, nauseousness, motion sickness) when transitioning between realities (e.g., transitioning between the virtual reality and augmented reality environments).
In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without such specific details. In other instances, well-known circuits have been shown in block diagram form in order not to obscure the present invention in unnecessary detail. For the most part, details considering timing considerations and the like have been omitted inasmuch as such details are not necessary to obtain a complete understanding of the present invention and are within the skills of persons of ordinary skill in the relevant art.
While the following discusses the present invention in connection with transitioning between different realities, such as virtual reality, augmented reality and real reality environments, the principles of the present invention may be applied to transitioning between other realities, such as a mixed reality environment (merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time). A person of ordinary skill in the art would be capable of applying the principles of the present invention to such implementations. Further, embodiments applying the principles of the present invention to such implementations would fall within the scope of the present invention.
Referring now to the Figures in detail,
Exemplary embodiments of headset 102 include a visor, a helmet, goggles, glasses and other similar arrangements. Examples of VR/AR headsets 102 include Oculus Rift® from Oculus VR®, VIVE® from HTC® Corporation and Gear VR® by Samsung® Electronics. A further example of VR/AR headset 102 presently available is the HoloLens® from Microsoft®. Furthermore, in one embodiment, headset 102 may include any one or more of the following: headphones to provide auditory feedback, vibration means to provide vibration feedback, and other sensors placed on or around the forward facing surface when in use.
System 100 further includes a system controller 104 in communication with display 103 of headset 102 via a network 105, which is capable of generating and/or controlling the graphical environment. System controller 104 may provide instructions to display 103, for example, by executing program code including an application program related to the VR and/or AR simulation.
In one embodiment, system controller 104 is a computing device, such as a mobile computing device (e.g., smartphone), which includes a camera and MEMS (microelectromechanical systems) sensors, such as an accelerometer, GPS (Global Positioning System) and a solid state compass, thereby enabling system controller 104 to be a suitable AR platform. In other embodiments, system controller 104 is a home video game console system, a set-top box or a media player. A description of the hardware configuration of system controller 104 being a mobile computing device is provided below in connection with
Network 105 may be, for example, a wireless wide area network, a Global System for Mobile Communications (GSM) network, a Wireless Application Protocol (WAP) network, a WiFi network, an IEEE 802.11 standards network, various combinations thereof, etc. Other networks, whose descriptions are omitted here for brevity, may also be used in conjunction with system 100 of
Additionally, system 100 may include a user interface device 106 (may be separate from system controller 104 as shown in
Furthermore, system 100 includes a smart wearable 107 (e.g., smartwatch) worn by user 101, such as on the user's wrist. In one embodiment, smart wearable 107 is configured to monitor the user's heart rate, the user's body temperature, levels of a user's sweat, etc. Such monitored information may be transmitted to system controller 104, such as via network 105. Such monitored information is one of the means for monitoring the user's experience in transitioning between realities as discussed further below. For example, such monitoring may include information that indicates that user 101 experienced a “transition shock” when transitioning between realities. A “transition shock,” as used herein, refers to the occurrence of adverse symptoms, such as disorientation, nauseousness or motion sickness, experienced by user 101 when user 101 transitions between different realties. Such symptoms may be determined based on the information acquired by smart wearable 107. For example, a high heart rate may indicate nausea or motion sickness. Cold sweating (sweating when the body temperature is not high) may indicate motion sickness. Excessive sweating may indicate disorientation.
Additionally, system 100 includes an object tracking system 108 connected to system controller 104 via network 105. Object tracking system 108 is configured to track objects in the field of view of user 101 and track the actions of user 101, such as tracking the user's hands, arms, legs, feet, head and torso. An “object,” as used herein, refers to something material (whether graphical image or physical) that can be perceived by a user's senses. Object tracking system 108 may be used to provide a real time image stream to display 103 of headset 102, for example, an image stream depicting an avatar of user 101 and/or of other objects in the field of view of user 101 in the virtual reality environment.
In one embodiment, object tracking system 108 includes a camera system 109, including one or more cameras, such as a two-dimensional camera, a three-dimensional camera, an infrared camera and a time of flight (ToF) camera. Camera system 109 may include complementary metal-oxide-semiconductor (CMOS) or charged-coupled device (CCD) image sensors, or any other form of sensor to form images. An example of camera system 109 is the Pro C920 or C930 Full HD by Logitech®. In one embodiment, camera system 109 may include a camera with an infrared filter, which can be used for object tracking. In one embodiment, camera system 109 may include an RGB camera, which can be used for generation of augmented reality simulations. In one embodiment, different frames of a single camera may be processed in an alternating manner, e.g., with an infrared filter and for RGB, instead of separate cameras. Images of more than one camera may be stitched together to give a field of view equivalent to that of the user.
In one embodiment, camera system 109 may be mounted to or integrated as part of headset 102, or otherwise adapted to be worn on the head of user 101, whereby the capture area of the camera is arranged to record an equivalent to a field of view of user 101 when wearing headset 102. Additional cameras may be arranged elsewhere to track other parts of the body of user 101. Use of additional camera(s) to cover areas outside the immediate field of view of user 101 (or outside the field of view of other cameras within the system) may provide the benefit of allowing pre-rendering (or earlier initiation of other calculations) involved with the augmented or virtual reality rendition of those areas.
In one embodiment, system controller 104 implements an application program for determining from the image stream provided by camera system 109 the arrangement of objects in the capture area. For object tracking, the application program may implement known techniques, such as feature extraction and identification. For example, one such technique is the speed-up robust features (SURF) algorithm. In one embodiment, object tracking system 108 may include an ultrasonic, magnetic, or other field tracker, which may be mounted on headset 102, which is able to sense a magnetic field generated from a local base station, video game console or other apparatus. The magnetic field tracker provides information about the sensed magnetic field to an application program, which derives the position and orientation of the magnetic field tracker, and thus headset 102, relative to a base station or the magnetic field tracker from such information.
System 100 further includes a database 110 connected to system controller 104. In one embodiment, database 110 is configured to store information pertaining to the monitored user actions and experience when user 101 transitions between realities as well as stores the changes in distances among the objects as well as the changes in distances between the objects and a reference object when user 101 transitions between realities as discussed further below. Furthermore, database 110 may be configured to store the transition speed when user 101 transitions between realities as discussed further below. Furthermore, as discussed further below, the monitored user experience in transitioning between realities may be mapped to the changes in the distances among the objects and/or between the objects and a reference object (as well as the transition speed) when user 101 transitions between realities, and such mapping may be stored in database 110.
System 100 is not to be limited in scope to any one particular architecture. System 100 may include any number of users 101, headsets 102, displays 103, system controllers 104, networks 105, user interface devices 106, smart wearables 107, object tracking systems 108, camera systems 109 and databases 110.

Other input mechanisms may be used to input data to system controller 104 that are not shown in

As stated in the Background section, currently, when a user transitions between different realities, such as between the virtual reality and the augmented reality environments or between the virtual reality and the real reality environments, the user may experience disorientation, motion sickness and/or nauseousness thereby degrading the user's experience.
The principles of the present invention provide a means for preventing transition shocks (e.g., disorientation, nauseousness, motion sickness) during transitions between realities (e.g., transitioning between virtual reality and augmented reality environments) as discussed below in connection with
As discussed above,
Referring to
In step 302, object tracking system 108 and system controller 104 determine the changes in the distances between the objects (including the distance among the objects as well as the distance between the objects and a reference object) as well as the speed of transitions during the transitions between realities. In one embodiment, the distance between the objects (e.g., avatar) displayed in the environment (e.g., virtual reality/augmented reality/real reality environment) as well as between the objects and a reference object (also referred to herein as the “reference point”), such as camera system 109, are determined from camera system 109 in conjunction with an object recognition service, such as OpenCV. For example, in one embodiment, images of objects are captured by camera system 109. The object in the image is recognized using the object recognition service. In one embodiment, the coordinate of the recognized object is determined by reconstructing the depth of the real reality environment (including when the real reality environment is being used to generate the virtual reality or augmented reality environment) from the point of view of camera system 109. Various “shape from X” techniques (e.g., shape from stereo, motion, shading or texture) may be used to generate the depth image from the point of view of camera system 109. A depth map stores, for each pixel in the real-world image, the distance from the XY (image) plane of camera system 109 (reference Object) to the real-world surface projected into that pixel. In this manner, the location (coordinate) of the objects as well as the distance between the objects (including the distance between the objects and a reference object, such as camera system 109) can be determined. Other embodiments for determining the distance between the objects include using triangle similarity. Changes in such locations and distances when user 101 transitions between realities may then be determined by determining the differences in the location (coordinate) of the objects and the differences in the distances between the objects before and after user 101 transitions between realties.
In one embodiment, the speed of transitions during the transitions between realities is determined by system controller 104 (e.g., time-tracking application, such as application 204) tracking the difference in time between the time user 101 initiates the transition and the time the transition is completed. In one embodiment, the initiation of a transition may be user-specified and the completion of the transition may be indicated by headset 102. In one embodiment, the completion of the transition may be indicated by system controller 104 identifying an exit or end activity that indicates the completion of the transition. In one embodiment, such exit or end activity may be tagged indicating the completion of the transition.
In step 303, system controller 104 maps the monitored user experience in transitioning between realities with the determined changes in the distances between the objects (including the distance among the objects as well as the distance between the objects and a reference object) as well as the speed of transitions during the transitions between realities. For example, system controller 104 maps the user experience (e.g., increased heart rate) in transitioning between the augmented reality and virtual reality environments with the change in the coordinate of the avatar object from 332,455,233 to 334,456,234 and the speed of the transition (e.g., fifteen seconds). Such information may be used by system controller 104 to determine the likelihood of a transition shock event occurring When the user transitions from a first reality (e.g., augmented reality environment) to a second reality (e.g., virtual reality environment). For example, if it can be determined that user 101 likely experienced a transition shock event (e.g., nausea due to an excessively high heart rate) when transitioning from the augmented reality environment to the virtual reality environment when the transition speed was fifteen seconds along with the avatar object changing coordinates from 332,455,233 to 334,456,234, then it may be inferred that user 101 would experience similar adverse symptoms under similar conditions. As discussed further below, if system controller 104 determines that user 101 will make a similar transition under a similar condition, system controller 104 may modify the distances between the objects (e.g., modify the distance between the object(s) and a reference object) when transitioning from the first reality to the second reality in an attempt to prevent user 101 from experiencing a transition shock event. Such mapped information may be stored in a data storage device (e.g., memory 205, disk unit 208) or in database 110.
In connection with the mapping discussed above, in one embodiment, system controller 104 may also generate models (statistical models) of previous transition events between realities and the speed of the transition events in transitioning between the realities in relation to motion in a physical space. “Motion,” as used herein, involves the motion or movement of objects during the transition between realities which is tracked by object tracking system 108. The relationship between the motion of objects during the transition between realities and the speed of the transition event may be statistically modeled. Such models may be stored in a data storage device (e.g., memory 205, disk unit 208) or in database 110.
In step 304, system controller 104 stores the monitored user actions during transitions between realities, such as in a data storage device (e.g., memory 205, disk unit 208) or in database 110.
Information pertaining to user actions and experiences in transitioning between realities will be used to determine the likelihood of a transition shock event occurring as discussed below in connection with
Referring to
In step 402, a determination is made by system controller 104 as to whether user 101 is likely to transition between realities (between the first and second realities). For example, system controller 104 determines whether the likelihood of user 101 transitioning between realities exceeds a threshold value. For instance, system controller 104 may develop a statistical model based on the stored user actions in transitioning between realities to assess a likelihood of whether user 101 is likely to transition between realities based on the monitored user actions of step 401. For example, the statistical model may include probabilities for transitioning between realities when user 101 preforms various actions. Such actions may be compared with the current monitored user actions (step 401) to determine a likelihood of transitioning between realities. Such a likelihood corresponds to a probability value which is compared to a threshold value.
In another embodiment, system controller 104 determines whether user 101 is likely to transition between realities based on the user's calendar. For example, system controller 104 may have access to the user's calendar application (e.g., application 204) which indicates when user 101 will be participating in the VR or AR environment. In such an example when the user is scheduled to participate in the VR or AR environment, system controller 104 would assess a probability value of user 101 transitioning between realities that exceeds the threshold value.
In another embodiment, system controller 104 determines when user 101 is likely to transition between realities based on feedback provided to an artificial intelligence application (e.g., application 204) running on system controller 104. User 101 may continually interact with the artificial intelligence application and provide feedback, such that based on certain commands, the artificial intelligence application can determine that user 101 is likely transitioning to another reality. In such an example, system controller 104 would assess a probability value of user 101 transitioning between realities to exceed the threshold value.
If system controller 104 does not determine that user 101 is likely to be transitioning between realities, then object tracking system 108 continues to monitor user actions in step 401.
If, however, system controller 104 determines that user 101 is likely to be transitioning between realities (between the first and second realities), then, in step 403, system controller 104 determines a location of objects in the first and second realities. In one embodiment, the location of objects in the first reality is determined using object tracking system 108 as discussed above in step 302. In one embodiment, the location of the same objects in the second reality is determined using statistical analysis. Such statistical analysis involves analyzing the stored data (e.g., stored in database 110) pertaining to object locations in the second reality. For example, if the avatar object named Mercury is positioned at coordinates 334,422,233; 334,412,212; and 334,423,321 during the times user 101 has transitioned to the augmented reality environment from the virtual reality environment, then it may be determined statistically (e.g., using directional statistics) that Mercury will likely be positioned at 334,422,222 when user 101 transitions to the augmented reality environment.
In step 404, system controller 104 determines a distance of the objects from a reference point in the first and second realities. That is, system controller 104 determines the distance of the object's location in the first reality environment from a reference point (e.g., camera system 109) as well as determines the distance of the object's location in the second reality environment from the reference point. The object's location (e.g., coordinate) in the first and second reality environments are determined in step 403. In one embodiment, the distance of the object from the reference point is determined based on the expected time of interaction (i.e., the time of interaction with the environment, such as the virtual reality environment). In one embodiment, the distance of the object from the reference point is determined based on the movement of objects in relation to each other. In one embodiment, the distance of the object from the reference point is determined based on the tagged object distances. For example, objects may be tagged with a distance between another object which may be used to determine the distance of the object from the reference point.
In step 405, system controller 104 determines the likelihood of a transition shock event occurring as the user transitions between the first reality environment to the second reality environment. A “transition shock” or a “transition shock event,” as used herein, refers to the occurrence of adverse symptoms, such as disorientation, nauseousness or motion sickness, experienced by user 101 when user 101 transitions between different realties. In one embodiment, the likelihood of the transition shock event occurring is ascertained based on one or more of the following: historical occurrences of symptoms experienced during transitions between realities (discussed in connection with
For example, suppose that user 101 experienced a high heart rate indicating nausea (historical occurrence of symptom) along with a downward movement of the head indicating nausea (historical occurrence of physical reaction) when user 101 transitions from the virtual reality environment to the augmented reality environment when the transition speed was fifteen seconds along with the avatar object changing coordinates from 332,455,233 to 334,456,234. A probability (e.g., value ranging from 0 to 1, with 1 indicating the event will definitely occur and 0 indicating the event will definitely not occur) that a transition shock event will occur is assessed by system controller 104 using the determined location of the objects in the first and second realities (determined in step 403) and the determined distance of the objects from a reference point in the first and second realities (determined in step 404). For example, if user 101 is likely to transition between the virtual reality environment to the augmented reality environment under similar conditions as in the example discussed above (e.g., similar transition speed with similar coordinates of the avatar object), then it may be inferred that user 101 would likely experience similar adverse symptoms (i.e., system controller 104 would assess a high probability that a transition shock event is likely to occur).
In step 406, a determination is made as to whether the likelihood of a transition shock occurring exceeds a threshold value, which may be user-selected. In one embodiment, the probability value ascertained in step 405 is compared with the threshold value. If the probability value does not exceed the threshold value, then, in step 407, the distances of the objects from the reference point in the first and/or second reality environment are not modified by system controller 104.
If, however, the probability value exceeds the threshold value, then, in step 408, camera system 109 and system controller 104 capture the images of the objects in the first and second realities, where the images of the objects in the first reality environment are captured by camera system 109 (and sent to system controller 104) and the images of the same objects to be presented in the second reality environment are generated by system controller 104 based on the determined location of the same objects in the second reality environment as determined in step 403.
In step 409, system controller 104 sends the captured images to an object recognition service, such as OpenCV. The object in the image is recognized using the object recognition service.
In step 410, system controller 104 modifies the distance of the object(s from the reference point in the first reality and/or the second reality so that the user will less likely experience a transition shock. For example, the distance of the objects) from the reference point in the first reality and/or the second reality is modified based on the position of future scenes and depths and specific user cohorts (e.g., a user of the video game of Minecraft® may have a different susceptibility to transition shock than an architect, where such susceptibility is determined based on historical experiences of transition shock during transitions between different realities).
In one embodiment, the distance of the object(s) from the reference point in the first reality and/or the second reality is modified based on previous locations of the objects and/or distances of the objects from the reference point where no transition shock was experienced by user 101. In one embodiment, based on previous transitions between realities, a model is generated by system controller 104 detailing locations of the objects and/or distances of the objects from the reference point where transition shocks occur and do not occur. Such a model may be used by system controller 104 to modify the distance of the object(s) from the reference point in the first, reality and/or the second reality so that the user will less likely experience a transition shock. To be clear, modifying the distance of the object(s) from the reference point involves changing the location (coordinate) of the objects.

In this manner, user 101 may be prevented from experiencing transition shocks (e.g., disorientation, nauseousness, motion sickness) when transitioning between realities (e.g., transitioning between the virtual reality and augmented reality environments). As a result, users will be able to participate in several different reality systems (e.g., virtual reality, augmented reality, real reality), one after the other, without experiencing transition shocks. That is, the technical problem of having different reality systems being able to be utilized by the user, one after the other, is addressed by the present invention. As discussed above, the present invention provides a technological solution to the technical problem by preventing users from experiencing transition shocks when transitioning between realities thereby encouraging user interactions between different reality systems, such as virtual reality and augmented reality systems. That is, integration and interchangeability between different reality systems is improved.
