## Background
RELATED APPLICATIONS
This application is a continuation-in-part of U.S. patent application Ser. No. 14/177,841 filed on Feb. 11, 2014, which claims priority to U.S. Provisional Application Ser. No. 61/886,240, both of which are expressly incorporated herein by reference.


BACKGROUND
Truly immersive virtual reality and augmented reality systems create environments that submerge the perceptual system of a user in computer-generated stimuli (e.g., a virtual world and/or a virtual view). Typically, these immersive systems captivate the senses of the user while blocking out stimuli from the physical world. The virtual world can be altered as a result of an input from the user and/or an interaction of the user with the virtual world.
Although, a goal of these systems is to create an immersive environment, the physical world can still be used to provide a context for the immersive environment. In particular, it is important to consider the environment and context of the user. For example, in the context of a user in a vehicle, immersive virtual reality and augmented reality systems can consider information about the user, the vehicle and the user in relation to the vehicle. This information can be used to generate an immersive environment that is customized to the user and the user's environment and can allow the user to perceive the immersive environment comfortably.

It is appreciated, that in some embodiments, the vehicle 902 in FIG. 9A could also be a vehicle on a predetermined path, for example an autonomous vehicle. In FIG. 9B, the predetermined path can be, for example, tracks 926. In FIG. 9B, the off-vehicle devices can include, but are not limited to, an imaging unit 928 mounted to a stationary structure 930 and in-track sensors 932. It is appreciated that other types of sensors and other types of off-vehicle devices can be implemented in different configurations and locations. In some embodiments, a network (e.g., similar to the network 922) can be used to communicate data between the off-vehicle devices and the vehicle computing device 102 and/or the VR engine 116 of FIG. 1.
Illustrative examples of types of data that can be obtained from the off-vehicle devices of FIG. 9B will now be discussed. For example, the imaging unit 928 can obtain images and/or video of the vehicle 924 as said vehicle passes by the stationary structure 930. The images can be used to determine speed and/or acceleration of the vehicle 924. The images can also be used to determine a location of the vehicle 924. The in-track sensors 932 can be used to measure or determine speed and/or acceleration of the vehicle 924. The in-track sensors 932 could also be used to measure a condition of the tracks 926, for example, a wet condition, an icy condition, among others. Further, the in-track sensors and/or the imaging unit 928 can be used to obtain and/or determine a pre-determined path (e.g., the path of the tracks 926, the route of the vehicle 924) of the vehicle 924 or a current location of the vehicle 924 on the predetermined path. In other embodiments, the predetermined path can be obtained from an on-vehicle device, for example, a navigation unit, an electronic control unit, a processor (e.g., the processor 104). In the case of an autonomous vehicle, the predetermined path could be obtained from an on-vehicle device such a navigation unit and/or an external source accessed via the network 122 of FIG. 1. The data obtained from the off-vehicle devices of FIG. 9B can be used to determine vehicle motion data and augment and/or generate a virtual view based on the vehicle motion data.
B. Virtual Reality Engine
The VR engine 116 of FIG. 1 and a system for in-vehicle dynamic virtual reality will now be discussed in detail with reference to FIGS. 1, 2 and 3. FIG. 3 illustrates a block diagram of a virtual reality (VR) engine 300 (e.g., the VR engine 116) according to an exemplary embodiment. For simplicity, not all components of FIG. 1 are shown in FIG. 3. The VR engine 300 includes a virtual reality data module 302, a dynamic virtual reality (VR) module 306 and a rendering module 308. In addition to the functionality described above with reference to FIG. 1, the aforementioned modules can access and/or receive vehicle data 318, user data 320 and other data 322, as well as communicate with a portable device 312 (e.g., the portable device 124) (e.g., the I/O device 126) and vehicle systems 316 (e.g., the vehicle systems 118). As discussed above, the portable device 312 can provide input and/or output to the VR engine 300. Further, the portable device 312 can provide output to a user (e.g., a vehicle occupant 202, 210).
In one embodiment, the virtual reality data module 302 receives vehicle data from the one or more vehicle systems 316 (e.g., the vehicle systems 118) of a vehicle. For example, the vehicle data 318 can include vehicle data metrics and parameters derived from the vehicle systems 118 and/or the vehicle sensors 120. In another embodiment, the portable device 312 can include one or more on-vehicle devices and/or one or more off-vehicle devices. The off-vehicle devices, as described above with reference to FIGS. 8, 9A and 9B, obtain vehicle data externally from the vehicle. In particular, the vehicle data can include data about the external environment of the vehicle.
In a further embodiment, the virtual reality data module 302 receives vehicle data from a portable device 312. In this embodiment, the portable device 312 can obtain the vehicle data independently from the vehicle (i.e., without directly connecting and/or receiving data from the bus 114 (e.g., a vehicle CAN bus), the vehicle systems 118, and/or the vehicle sensors 120). For example, the portable device 312 can include position and motion sensors. The portable device 312 can gather vehicle data utilizing the position and motion sensors. In one embodiment, the portable device 312 is operably connected for computer communication to an output device.
The vehicle data includes vehicle dynamics data of the vehicle. The vehicle data 318 includes vehicle data metrics and parameters derived from the vehicle sensors 120. For example, vehicle data can include, but is not limited to, vehicle location data, vehicle orientation data, vehicle system state data, data related to one or more vehicle systems and/or components, vehicle environment data (e.g., interior and exterior environment data) among others. The vehicle data 318 can also include navigation data, for example, location data, direction data (e.g., origin, destination, point of interest), a predetermined path of the vehicle, among others.
The vehicle data 318 can also include vehicle dynamics data that describes the dynamics of the vehicle and the motion of vehicle (e.g., velocity, direction, acceleration, yaw rate, steering rate, steering angles). Vehicle dynamics data can include, but is not limited to, real time data concerning the speed level, the acceleration rate, the yaw rate, the steering wheel position, the brake position, the throttle position, the transmission gear position of the vehicle, driver commands, dynamic car responses, tire and road forces, among others. Further, vehicle dynamics data can include derivatives of said data.
In some embodiments, the vehicle data 318 can be received from remote sources, for example, the network 122 and/or off-vehicle devices. In one embodiment, the VR data module 302 can receive predictive vehicle data or can determine predictive vehicle data based on the vehicle data 318 and/or the vehicle dynamics data. For example, vehicle predictive motion data can be based on pedal positions, vehicle system status/control, current vehicle location, vehicle destination information, among others. As an illustrative example, the position of the accelerator pedal of the vehicle and the time delay between pedal positions can be modeled with a dynamic model of the vehicle to determine vehicle predictive motion data. In another example, information from the accelerator pedal and traffic information (e.g., received from an off-vehicle device indicating a traffic light turning green) can be used to determine vehicle predictive motion data.
The virtual reality data module 306 also receives user data 320. For example, the user data 320 can be received from one or more of the portable devices 312. The user data 320 includes tracking data, interaction data, user input data, among others. The user data can be based at least in part, on data from vision sensors (e.g., vehicle sensors 120, cameras, gesture/motion sensors), tracking systems, the portable device 312, the I/O device 312, and other sensors and systems that provide data about the user's interaction, position, orientation, location and motion. For example, the user data 320 can include position, orientation and location information about the user. In another embodiment, the user data 320 can include position, orientation and location information about the user in relation to the vehicle, for example, based in least in part, on the vehicle data 318 (including the vehicle dynamics data). Thus, in one embodiment, the user data 320 can provide information on the user's motion and position and how the user's motion and position is affected by the vehicle dynamics. The user data can also include health data about the user, for example, from health monitoring devices (e.g., portable medical devices worn by the user, wearable computing devices, in-vehicle biological health monitoring devices). In some embodiments, the user data can also be received from other networks 122 and/or the vehicle systems 316.
In another embodiment, the virtual reality data module 302 also receives other data for facilitating dynamic in-vehicle virtual reality. The other data 322 can include can include big data from the vehicle systems 316, the portable device 312, and/or other networks 122. For example, other data 322 can include environmental data associated with the vehicle (e.g., interior, exterior), road conditions (e.g., bumpy roads, slick roads, traffic conditions), weather conditions, vehicle temperature, among others. In another embodiment, the other data 322 can include driver action data, for example, driving history, fuel efficiency, interactions with other vehicle systems, gestures, motion relative to the vehicle, among others. Further, in some embodiments, the other data 322 can include social media data from, for example, the other networks 122.
The dynamic VR data module 306 generates a virtual view based on the vehicle data, the user data and a virtual world model. In one embodiment, a data store stores a virtual world model, the virtual world model including one or more components that define the virtual view. For example, in FIG. 3, a data store 310 can store a virtual world model and design data. The virtual world model and design data can include game themes, software or program instructions to define and generate a virtual world and/or a virtual view. In another embodiment, the memory 106 and/or the disk 108 can store some or all of the aforementioned virtual world model and design data. In another embodiment, the virtual world model and design data is received from remote sources, for example, the network 122.
An exemplary virtual world model will now be described with reference to FIGS. 4 and 5. FIG. 4 illustrates an exemplary virtual world data model 400 diagram including data flow according to an exemplary embodiment. FIG. 5 is a schematic class diagram 500 of a virtual reality world 502 including a group of node classes 504 of the virtual world model of FIG. 4 according to an exemplary embodiment. The node classes, objects, properties, references, methods and events (i.e., the one or more components that define the virtual view) discussed with FIGS. 4 and 5 are exemplary in nature and are not intended to be limiting. Generally, a virtual world model is a collection of many individual operations and objects that define the virtual world and one or more virtual views. The virtual world model can be defined in various modeling and programming languages, for example, virtual reality modeling language (VRML), DirectX, OpenGL, Unity, among others. As illustrated in FIG. 5, the virtual world 502 can include one or more virtual views 506. The virtual world 502 and the virtual view 506 can also include one or more virtual objects 510. The virtual view 506 and the virtual object 510 are defined by node classes, and in the example of FIG. 5, the group of node classes 504. In some embodiments, nodes can be grouped and applied to one or more virtual views 506 and/or virtual objects 510 in a hierarchy structure. For example, the group of node classes 504 can apply to parent and child nodes of the virtual views 506 and/or virtual objects 510 associated with a particular group of nodes (i.e., the group of node classes 504).
In the illustrated embodiment of FIG. 5, the group of node classes 504 includes a view node class 512, a world structure node class 514, an eventsIn node class 516 and an eventsOut node class 518. Each node class can include components that define and/or modify the node classes, for example, other nodes, properties, fields, methods and/or references. In some embodiments, the nodes, properties, fields, methods and/or references can be predefined based on the virtual world, for example, for a particular theme, game, among others. Additionally, in some embodiments, the nodes, properties, fields, methods and/or references can be predefined based on the user, for example, based on user preferences. Other node classes, properties, fields, methods and/or references not included in FIGS. 4 and 5 can be implemented and may be based on the different modeling and programming languages mentioned above.
The group of node classes 504 of FIG. 5 will now be discussed in detail. The view node class 512 defines the position and/or the orientation of the virtual view 506, the virtual object 510 and/or operations associated with the virtual view 506 and/or the virtual object 510. For example, in FIG. 5, the transform node can be used to perform geometric transformations and includes the properties position, rotation and scale. The imageEffect node handles image post processing effects. Exemplary image post processing effects include, depth of field, motion and blur, among others. The behavior node can be used to enable and disable different behaviors, for example, animation and motion. The visualEffects node can be used to define visual effects, for example, line renderers, halo effects, trail renders, among others. The rendering node can be used to define settings and components for rendering in-game and user interface elements.
The world structure class node 514 defines the structure and appearance of the virtual view 506, the virtual object 510 and/or operations associated with the virtual view 506 and/or the virtual object 510. For example, the geometry node can be used to define shapes. The appearance node can be used to define texture and material. The terrain node can be used to define aspects of a terrain and landscape. The collision node defines which objects in a virtual view are collidable.
The eventsIn class node 516 defines the types and names of events that each node can receive or generate. For example, the EventManager node can define custom events and includes event handlers and listeners that determine event triggers (e.g., determined from user data (e.g., user input), vehicle data) to initialize specific events. The type field defines a type of the event, the node field defines which node(s) the event applies to and the set_fieldname method can be used to modify a value of a field during the event. The eventsOut class node 518 manages execution and routing of the event. The fieldname_changed field indicates what field(s) are changed during the event, the type field defines the type of the event, the node field can define which node the event applies to and the route method defines how the event is sent to a node and how the event is received and generated by a node. Again, the class nodes and components in FIG. 5 are exemplary in nature and other class nodes and components can be implemented with the systems and methods discussed herein. The class nodes and components can be augmented according to at least one of the vehicle data and the user data to generate a dynamic virtual world and/or virtual views to a user. Specifically, the vehicle data and the user data can be used to initialize nodes, set properties and fields and initialize or define events.
Referring again to FIG. 4, the model 400 includes, one or more components that define a virtual view. For example, in FIG. 4, the model includes a view class node 402, a world structure class node 404, an eventsIn class node 406 and an eventsOut class node 408. The class nodes in FIG. 4 can include similar methods, properties, fields and references as the class nodes described with FIG. 5. FIG. 4 also illustrates exemplary data flow to the class nodes, for example, for augmenting the class nodes. Specifically, the dynamic VR module 306 can use these types of data to augment specific class nodes. As discussed in FIG. 3, the data can include vehicle data 318, user data 320 and/or other data 322. The types of data illustrated in FIG. 4 are types of vehicle data 318, user data 320 and/or other data 322 in FIG. 3. Specifically, in FIG. 4, the data includes, but is not limited to, vehicle motion data (including vehicle dynamics data) 412, user motion data 413, vehicle motion predictive data 414, navigation data 416, big data 418 and driver action data 420.
Referring again to FIG. 3, the dynamic VR module 306 modifies and/or augments one or more components of the virtual world model 400 based on at least one of the vehicle data and the user data. As shown in FIG. 4, the arrows illustrate the flow from the different types of data to the VR model components. Accordingly, the arrows illustrate exemplary flow of data that can be used to augment specific VR model components. For example, vehicle motion data 412 (e.g., vehicle dynamics data, vehicle velocity, direction, acceleration, jerk, vehicle occupant motion data) can be used to augment components of the view class node 402. User motion data 413 (e.g., position, orientation, location, input) can be used to augmented components of the view class node 402. Further vehicle motion predictive data 414 (e.g., pedal positions, auto cruise control) can also be used to augment the view class node 402. In another embodiment, the navigation data 416 (e.g., navigation location, directions) can be used to augment the world structure class node 404. The big data 418 (e.g., speed bumps, road conditions, steering conditions) can also be used to augment the world structure class node 404. Further, the big data 418 can be used to augment the eventsIn class node 406. The driver action data 420 (e.g., fuel efficiency, driver input, audio) can also be used to augment the eventsIn class node 406.
As discussed above, the view class node 402, the world structure class node 404, the eventsIn class node 406 and the eventsOut class node 408 define the virtual view and can be augmented using at least one of vehicle data and user data to provide a dynamic virtual view to a user. In particular, the data types in FIG. 4, can be used to augment the components of the virtual world model 400 thereby generating a virtual view that can include one or more virtual events 410. In one embodiment, the dynamic VR model 306 augments one or more properties of the one or more components of the virtual world model based on the vehicle data and the user data. For example, the one or more properties of the one or more components can include those properties of the class nodes illustrated in FIG. 5. In one embodiment, one or more of the properties can include a motion property defining a motion of the component. For example, the view class node 402 can include a property, for example, transform class node that defines the position, the rotation and or the scale of an object. Based on at least one of the vehicle data and the user data, the transform class node can be augmented to change the position, rotation and or scale of the object. As an illustrative example, and referring to FIGS. 4 and 5, a VR object 510 can be defined as a ball (i.e., defined by the world structure class node 514, for example, the geometry class node). The vehicle motion data 412 (e.g., vehicle dynamics data) can be used to augment a feature of the ball. For example, using the view class node 402 and the transform class node, the position, rotation and/or the scale of the ball can be set based on the vehicle motion data 412. Accordingly, the VR object 510, (i.e., the ball) is synchronized with the vehicle motion data 412.
Referring again to FIG. 3, the rendering module 308 renders the virtual view from the dynamic VR module 306 to an output device by controlling the output device to update display of the virtual view according to the vehicle dynamics data. For example, the dynamic reality module 306 renders the virtual view the I/O device 314 (e.g., an output device). In one embodiment, the rendering module 308 determines vehicle motion data 412 based on the vehicle dynamics data (i.e., the vehicle data 318). The rendering module 308 can also determine user motion data 413 representing motion of the user relative to the vehicle based on the user data 320 and the vehicle data 318. For example, in one embodiment, the portable device 312 and/or the I/O device 314 can include accelerometer sensors and/or gyroscope sensors that help determine a position, a location and/or an orientation of the user in relation to the vehicle. The vehicle motion data 412 and/or the user motion data 413 can be used to augment one or more components of the virtual world model 400, thereby controlling the output device to update display of the virtual view according to the vehicle dynamics data. In another embodiment, the rendering module 308 can augment the rendering speed (e.g., the frames per second, frame rate, frame update rate defined and implemented by the graphics rendering hardware/software) of the I/O device 314 directly based on the vehicle motion data 412 and/or the user motion data 413.
In a further embodiment, the rendering module 308 determines a temporal-motion rendering speed based on the vehicle motion data and the user motion data. The temporal-motion rendering speed is a correlation between the vehicle motion data and the user motion data. In another embodiment, the temporal-motion rendering speed also considers a time component from the vehicle data. The temporal-motion rendering speed is a post image processing and rendering property (e.g., frames per second, frame rate, frame update rate) that minimizes the difference between the vehicle motion data and the user motion data. The rendering module 308 can render the virtual view to the output device by controlling the output device to update display of the virtual view based on the temporal-motion rendering speed. For example, the rendering speed (e.g., the frames per second, frame rate, frame update rate) implemented by the graphics hardware and/or software of the I/O device 316 can be augmented based on the temporal-motion rendering speed. In another embodiment, the dynamic VR module 306 augments one or more properties of the one or more component of the virtual world model based on the temporal-motion rendering speed. For example, the view class node 402 can include a rendering properties and/or properties related to motion (See FIG. 5). In one embodiment, these properties can include frames per second, frame rate and/or a frame update rate.
By updating the virtual view according to the vehicle dynamics data in real-time, the virtual view presented to the user is dynamic and considers the vehicle motion and the user motion, thereby simulating the vehicle motion and the user motion in the virtual view in real-time. Said differently, one or more components of the virtual world model are synchronized based on at least the vehicle data and the user data, including the vehicle dynamics data and the user motion data. Not only does this provide a truly immersive virtual reality environment for the user, but virtual reality motion sickness can be minimized, because the virtual view considers vehicle dynamics and user motion.
II. Exemplary Methods for Dynamic In-Vehicle Virtual Reality
The dynamic in-vehicle virtual reality system illustrated in FIGS. 1-5, 8, 9A and 9B described above will now be described in operation with reference to a method of FIG. 6. It will be appreciated that the systems and components discussed above with references to FIGS. 1-5 can similarly be implemented with the method of FIG. 6. The method of FIG. 6 includes at block 602, receiving vehicle data and user data from one or more portable devices, wherein the vehicle data comprises vehicle dynamics data of the vehicle. For example, referring to FIG. 3, the VR data module 302 can receive vehicle data 318. The vehicle data 318 can include vehicle dynamics data. In one embodiment the vehicle data 318 is received from one or more portable devices 312 (e.g., on-vehicle devices and/or off-vehicle devices). In another embodiment, the vehicle data 318 is received from one or more vehicle systems 316. The VR data module 302 can also receive user data 320 from one or more portable devices 312 (e.g., on-vehicle devices and/or off-vehicle devices). In another embodiment, the use data 320 is received from vehicle systems 316.
In one embodiment, the portable device is an off-vehicle device that obtains the vehicle data externally from the vehicle. For example, the off-vehicle devices 804 of FIG. 8. As an illustrative example, the off-vehicle device is an imaging unit mounted to a stationary structure external to the vehicle. The vehicle data can include data about the external environment of the vehicle.
Referring back to FIG. 6, at block 604, the method includes generating a virtual view based on the vehicle data, the user data and a virtual world model. The virtual world model includes one or more components that define the virtual view. FIG. 4 illustrates an exemplary virtual world model 400 diagram including data flow according to an exemplary embodiment. The virtual world model 400 includes one or more components that define the virtual view. For example, the view node class 402, the world structure node class 404, the events in node class 406 and the events out node class 408 are exemplary components that define the virtual view. In particular, these node classes define one or more virtual views and one or more virtual objects of the virtual world. The node classes can contain other nodes, properties, fields, methods and references (See FIG. 5).
In one embodiment, generating the virtual view includes augmenting one or more components of the virtual world model according to at least one of the vehicle data and the user data. For example, the view node class 402, the world structure node class 404, the events in node class 406 and the events out node class 408, and/or, nodes, properties, fields, methods and references associated with these nodes, can be augmented based on at least one of the vehicle data and the user data. In FIG. 4, the vehicle motion data 412, the user motion data 413, the vehicle motion prediction data 414, the navigation data 416, the big data 418 and the driver action data 420 are exemplary types of data that can be used to augment one or more of the components of the virtual world model 400.
In one embodiment, the method includes determining an orientation and a location of the vehicle based on the vehicle data. For example, navigation data 416 (e.g., from for example the GPS 110) can be used to determine the orientation and the location of the vehicle. The dynamic VR module 306 and/or the rendering module 308 can determine the orientation and the location of the vehicle based on the vehicle data 318. The method can also include determining an orientation and a location of the user relative to the vehicle based on the user data and the vehicle data. For example, the dynamic VR module 306 and/or the rendering module 308 can determine the orientation and the location of the user relative to the vehicle based on the user data 320 and the vehicle data 318. For example, the VR devices (e.g., tracking devices, the HMD 202, the portable device 208) can include sensors (e.g., accelerometers, gyroscopes, compasses) that provide user data for determining the orientation and the location of the user relative to the vehicle.
Augmenting one or more components of the virtual world model can be based on at least one of the orientation and the location of the vehicle and the orientation and the location of the user. As a non-limiting example, the dynamic VR module can augment the world structure class node 404, with the orientation and the location of the vehicle and the orientation and the location of the user in relation to the vehicle to provide real-time world structures. For example, the terrain class node (See FIG. 5) can be augmented to provide a terrain or landscape in the virtual view that includes a component based on the orientation and the location of the vehicle and the orientation and the location of the user in relation to the vehicle.
In another embodiment, one or more virtual events 410 can be augmented or created based on at least one of the vehicle data 318 and the user data 320. As an illustrative example, driver action data 420 can be used to augment the eventsIn class node 406. Driver action data 420, can include for example, driving history, fuel efficiency, interactions with other vehicle systems, gestures, motion relative to the vehicle, among others. As a non-limiting illustrative example, a user 312 (i.e., a vehicle occupant 202), may roll down a vehicle window (not shown). This driver action is determined based on vehicle data 318 from the vehicle systems 316 (e.g., power window vehicle system) and user data 320 from the VR devices 316 (e.g., tracking devices) indicating that the user 312 has rolled down the vehicle window. In response, the dynamic VR module 306 can augment, for example, the eventIn class node 406, to trigger an event in the virtual view associated with the user 312 rolling down the vehicle window. For example, a simulation of the wind from the vehicle window can be presented in the virtual view, among others. As another illustrative example, the dynamic VR module 306 can define the structure of the simulation of the wind based on a temperature determined from the vehicle data 318. For example, if the temperature is a certain degree, the simulation of the wind in the virtual view may include particles of snow. This can be defined by augmenting the eventsIn class node 406 of the world structure class node 404. The eventsOut node 408 can then route the event to create the virtual event 410.
In a further embodiment, the method includes determining vehicle motion data based on the vehicle dynamics data. The dynamic VR module 306 and/or the rendering module 308 can determine the vehicle motion data based on the vehicle data 318, which includes vehicle dynamics data. As discussed above, vehicle motion data 412 defines real-time motion of the vehicle. Further, the vehicle motion data can also include predictive vehicle motion data determined based on the vehicle data 318, the user data 320 and/or the other data 322. For example, the predictive vehicle motion data can be based on pedal positions, cruise control, destination information, among others.
In another embodiment, the vehicle motion data is based on vehicle data obtained from the off-vehicle devices. In a further embodiment, the vehicle motion data is based on a predetermined path of the vehicle. The predetermined path of the vehicle can be obtained from one or more portable devices 312, for example, road sensors (e.g., off-vehicle device), a navigation unit (e.g., an on-vehicle device), among others. In one embodiment, determining the vehicle motion data includes determining at least a velocity and an acceleration of the vehicle based on the predetermined path of the vehicle.
As an illustrative example, a vehicle with a predetermined path can be a roller coaster. In this example, information about the predetermined path and/or an initial set of conditions (e.g., physical dimensions of the track, hill height, number of loops, run time, angle of decent, track material type, mass, speed, force) can be obtained from the roller-coaster (e.g., an ECU) and/or sensors associated with the roller coaster, for example, sensors along the track of the roller coaster. Based on the initial set of conditions, velocity and acceleration can be calculated, for example, using Newton's second law, circular motion equations, among others.
As another illustrative example, a vehicle with a predetermined path can be a self-driving car (e.g., an autonomous vehicle), the path of which has already been determined and stored, for example, at the vehicle (e.g., the ECU, navigation device). The controls of the self-driving vehicle (e.g., steering angle, acceleration position) can serve as inputs to determine vehicle emotion data, for example, velocity and/or an acceleration of the vehicle.
In a further embodiment, the method can also include determining user motion data representing motion of the user relative to the vehicle based on the user data and the vehicle data. The user motion data can be based on the vehicle data and the user data 320 and can be determined by the dynamic VR module 306 and/or the rendering module 308.
Referring again to FIG. 6, at block 608 the method includes rendering the virtual view to an output device by controlling the output device to update the display of the virtual view according to the vehicle dynamics data. For example, the dynamic reality module 306 renders the virtual view to one or more of the VR devices 316 (i.e., the HMD 206, the portable device 208). In one embodiment, the rendering module 308 renders the virtual view to an output device by controlling the output device to update the display of the virtual view according to the vehicle motion data 412 and the user motion data 413. This can be accomplished, in one embodiment, by directly augmenting the rendering speed (e.g., the frames per second, frame rate, frame update rate) implemented by the graphics hardware and/or software of the portable devices 312. In another embodiment, shown at block 606, the dynamic VR module 306 augments one or more components of the virtual world model 400 according to the vehicle motion data 412 and the user motion data 413.
In another embodiment, the method includes determining a temporal-motion rendering speed based on the vehicle motion data and the user motion data. Rendering the virtual view can include controlling the output device to update display of the virtual view based on the temporal-motion rendering speed. The temporal-motion rendering speed is a correlation between the vehicle motion data 412 and the user motion data 413. In another embodiment, the temporal-motion rendering speed also considers a time component from the vehicle data. The temporal-motion rendering speed is a post image processing and rendering property (e.g., frames per second) that minimizes the difference between the vehicle motion data 412 and the user motion data 413. The rendering module 308 can render the virtual view to the output device by controlling the output device to update display of the virtual view based on the temporal-motion rendering speed. For example, the rendering speed (e.g., the frames per second, frame rate, frame update rate) implemented by the graphics hardware and/or software of the portable devices 312 can be augmented based on the temporal-motion rendering speed.
In a further embodiment, shown at block 606, the dynamic VR module 306 augments one or more properties of the one or more component of the virtual world model based on the temporal-motion rendering speed. For example, the view class node 402 can include a rendering properties and/or properties related to motion (See FIG. 5). In one embodiment, these properties can include frames per second, frame rate and/or a frame update rate. In this way, the virtual view presented to the user is dynamic and simulates the vehicle motion in real-time. Said differently, one or more components of the virtual world model are synchronized based on at least the vehicle data and the user data, including the vehicle dynamics data and the user motion data. Not only does this provide a truly immersive virtual reality environment for the user, but also virtual reality motion sickness can be minimized, because the virtual view considers the vehicle dynamics and the user motion. Further, each virtual view presented to the user can be updated and maintained based on the vehicle dynamics data. For example, if a virtual view presents user settings (i.e., not in a game play mode), the virtual view is always updated and maintained based on the vehicle dynamics data.
In some embodiments, virtual reality objects and/or operations can have predefined rendering speeds. As an illustrative example, certain objects or certain virtual worlds may be set to rendering speeds of 25 ms. This predefined rendering speed can be adjusted based on the vehicle dynamics data as discussed above. Thus, in some embodiments, the temporal-motion rendering speed can be based on a predefined rendering speed, vehicle motion and user motion. Further, the temporal-motion rendering speed can also consider other types of data based on the user. For example, as discussed above, other data 322 can include health data associated with the user 312. If for example, the health data indicates motion or sensory issues (e.g., disorientation, vertigo, motion sickness), the temporal-motion rendering speed can be adjusted based on the health data to minimize the motion or sensor issues.
III. Illustrative Examples
Illustrative examples of dynamic virtual views generated by the methods and systems discussed herein will now be described with reference to FIGS. 7A and 7B. FIG. 7A illustrates a virtual view 702 and FIG. 7B illustrates a virtual view 704 from a fishing virtual reality game, the objects and operations of which are defined by a virtual world model, for example the virtual world model 400 of FIG. 4 and the schematic class diagram 500 of a virtual reality world of FIG. 5. Specifically, the virtual views 702, 704 are generated based on the vehicle data, the user data and the virtual world model, the virtual world model including one or more components that define the virtual views 702, 704. The virtual views 702, 704 can be displayed in one embodiment, on the output device 126 (FIG. 1). In another embodiment, the virtual views 702, 704 can be displayed on the portable device 124 (FIG. 1).
The virtual view 702 includes one or more virtual reality objects, including a landscape 706, a sun 708, a fish 710 and a water object 712. The water object 712 includes one or more waves 714. Again, the objects and operations of the virtual view 702 are defined by a virtual world model. One or more components of the virtual world model can be augmented based according to at least one of the vehicle data and the user data. In particular, in one embodiment, the virtual world model can be augmented based on vehicle dynamics data and/or the virtual view 702 can be rendered to an output device by controlling the output device to update display of the virtual view according to the vehicle dynamics data. In this way, the virtual view and objects of the virtual view are influenced by the vehicle data and/or the user data and the virtual view and objects of the virtual view are synchronized with the vehicle dynamics data. For example, the dynamic VR module 306 can augment the world structure class node 404 (e.g., the terrain class node) to dynamically generate and update the virtual view 702 with objects based on a location and an orientation of the vehicle 200 and a location and an orientation of the vehicle occupant 202. As an illustrative example, the vehicle 200 is driving in a mountainous region during the day. Accordingly based on the location and the orientation of the vehicle 200 and a time component determine from the vehicle data 318, the appearance and the terrain of the landscape object 706 in the virtual view 702 includes mountains and the sun 708. This is accomplished by augmenting the world structure class node 404 with the location and the orientation of the vehicle 200 and a time component determine from the vehicle data 318.
As another example, the fish object 710 can be generated as a type of fish indigenous to the location and the orientation of the vehicle 200 and the location and the orientation of the vehicle occupant 202. Further, the position of the fish object 710 can also be generated based on the location and the orientation of the vehicle 200 and the location and the orientation of the vehicle occupant 202. For example, the view class node 402 defining the position and the orientation of the fish object 710 can be augmented to present a point of view to the vehicle occupant 202 based on the location and the orientation of the vehicle 200 and the location and the orientation of the vehicle occupant 202.
As a further example, the water object 712 in the virtual view 702 can be generated based on the vehicle dynamics data. As an illustrative example, the vehicle data 318 can indicate a steady speed and yaw rate indicating a straight direction. Further, the user data 320 can indicate stead user motion. Accordingly, in FIG. 7A, the waves 714 appear clam and steady based on the vehicle data 318 and the user data 320. However, if the vehicle 200 suddenly increases in speed, as shown in FIG. 7B, the water object 724 including one or more waves 720 appear rough. In other embodiments, the water object 724 including the one or more waves 720 can be generated by altering the parallax motion or depth of motion of the view class node 402 based on the vehicle dynamics data.
In another embodiment, the yaw rate of the vehicle 200 and motion of the vehicle occupant 202 can be used to augment the view class node 402 of the boat object to generate a virtual view with the boat turning or moving based on the yaw rate of the vehicle 200 and the motion of the user 202. As is apparent, many variations of the virtual view can be generated based on the vehicle data 318, the user data 320 and the other data 322. In addition, in a situation where the virtual view is not in a game play mode (i.e., the virtual view presents game settings, user settings, start-up instructions), the virtual view is still generated and updated according to the vehicle dynamics data. Accordingly, by updating the virtual view according to the vehicle dynamics data in real-time, the virtual view presented to the user is dynamic and considers the vehicle motion and the user motion, thereby simulating the vehicle motion and the user motion in the virtual view in real-time. Not only does this provide a truly immersive virtual reality environment for the user, but virtual reality motion sickness can be minimized, because the virtual view considers the vehicle dynamics and the user motion.
