Detailed Description



[0025] The present disclosure generally relates to a method and a system for tracking virtual reality experiences. In some embodiments, one or more techniques disclosed herein leverage information included in a software development kit (SDK) of a virtual reality (VR) headset to track one or more locations of a user's gaze, hand position, head position, and the like, while interacting with a VR environment. Based on the one or more locations, the one or more techniques disclosed herein may generate a heat map that visually illustrates area of the VR environment that are most frequently viewed by the users during the VR experience. In some embodiments, the one or more techniques discussed herein may be tuned to a level of granularity defined by the user. For example, a user may define a level of detail in which the one or more systems disclosed herein generate the heat map.

[0026] In some embodiments, the one or more techniques disclosed herein implement an object relational database to store the plurality of location coordinates. Such object relational database aids in efficient storage and retrieval of the one or more location coordinates for the generation of the heat map. With this information, an entity associated with the system may be able to dynamically position elements in three-dimensional space based on feedback from one or more users. For example, if a content developer wants a user to see an advertisement on the wall of a building in three-dimensional space, the developer may place the advertisement on the wall in which the developer assumes most people will see. As an increased number of people partake in the VR simulation, the one or more techniques disclosed herein help identify if the initial placement of the advertisement, for example, was correct, or if the placement of the advertisement needs to be moved.

[0027] The term "user" as used herein includes, for example, a person or entity that owns a computing device or wireless device; a person or entity that operates or utilizes a computing device; or a person or entity that is otherwise associated with a computing device or wireless device. It is contemplated that the term "user" is not intended to be limiting and may include various examples beyond those described.

Because the information transmitted may be personal or confidential, security concerns may dictate one or more of these types of connection be encrypted or otherwise secured. In some embodiments, however, the information being transmitted may be less personal, and therefore, the network connections may be selected for convenience over security.

[0038] Network 115 may include any type of computer networking arrangement used to exchange data. For example, network 115 may include any type of computer networking arrangement used to exchange information. For example, network 115 may be the Internet, a private data network, virtual private network using a public network and/or other suitable connection(s) that enables components in computing environment 100 to send and receiving information between the components of system 100.

[0039] Web server 116 may be configured to communicate with application 112 executing on client device 101. For example, web server 116 may provide one or more web pages that allows client device 101 to access functionality of back end computing system 104. In some embodiments, web server 116 may transmit content to client device 101, which is subsequently processed by application 112 for display through a GUI of client device 106.

[0040] API server 118 may include a computer system configured to execute one or more APIs that provide various functionalities related to the operations of back end computing environment 104. In some embodiments, API server 118 may include API adapter that allow API server 118 to interface with and utilize enterprise APIs maintained by back end computing environment 104 and/or an associated entity that may be housed on other systems or devices. In some embodiments, APIs may provide functions that include, for example, receiving one or more parameters for a query from client device 101, executing a query based on the one or more parameters, linking client device 101 to back end computing environment 104, and any other such function related to the analysis of user movement and actions during a VR session. API server 118 may include one or more processors 134 and one or more API databases 136, which may be any suitable repository of API information. Information stored in API server 118 may be accessed via network 115 and/or network 105 by one or more components of back end computing environment 104.

For example, analysis server 120 may receive a plurality of coordinates corresponding to bodily movements of the user wearing the VR device 108 during the VR experience.

[0043] Analysis server 120 may receive the one or more parameters from client device 101 via an API, generated by API server 118, that links client device 101 to back end computing environment 102. In some embodiments, the plurality of coordinates may correspond to a location of a user's gaze during the VR experience. In some embodiments, the plurality of coordinates may correspond to a location of a user's head during the VR experience. In some embodiments, the plurality of coordinates may correspond to a location of a user's hands during the VR experience.

[0044] Analysis server 120 may further receive one or more parameters to generate a query to execute against database 124. The query may be used to generate a heat map of user's gaze throughout the VR experience. For example, analysis server 120 may query database to determine one or more hot spots or dead zones in the VR simulation. Based off of this information, an entity associated with back end computing environment 104 may dynamically position elements in 3D space in real-time (or near real-time). The one or more parameters of the query may include a criteria. The criteria may include, for example, a level of granularity for the query. The level of granularity may be directed to a level of detail in which analysis server 120 analyzes the set of coordinates.

[0045] In operation, client device 101 may access functionality of back end computing environment 104 via application 114 executing thereon. In some embodiments, client device 106 may transmit SDK by accessing VR application 112. SDK may include one or more coordinates corresponding to a gaze of a user during a VR experience. In some embodiments, the one or more coordinates may further correspond to one or more bodily location, such as head location and hand locations. API server 118 may store the received coordinate into database 124. API server 118 is configured to generate an API to receive one or more query parameters for database 124. For example, web server 116 may notify client device 101 that an API to query database 124 is available. Based on the received query, analysis server 120 may generate a heat map for display to the user. The heat map may illustrate one or more locations in the VR simulation that the user concentrated on (i.e., looked at/viewed) most frequently.

[0046] Figure 2 is a flow diagram of a method 200 of tracking a virtual reality experience of a user, according to one embodiment. Method 200 begins at step 202. At step 202, back end computing environment 104 receives a plurality of location coordinates of a user operating a VR headset during a simulation. In some embodiments, back end computing environment may receive the plurality of location coordinates via VR application 112 executing on client device 106. For example, client device 106 may automatically transmit the one or more parameters to web server 116 via VR application 11. In some embodiments, back end computing environment 104 may receive the plurality of location coordinates via receiving SDK. For example, SDK may include the plurality of coordinates recorded during the VR session.

[0047] At step 204, back end computing environment 104 may upload the plurality of location coordinates to database 124. API server 118 may parse, for example, the received SDK to identify the plurality of location coordinates contained therein. In some embodiments, API server 118 may further upload a coordinate system of VR device 108 stored in SDK. For example, the coordinate system of VR device 108 may provide additional information about the relative location of each location coordinate. Each location coordinate of the plurality of location coordinates may include an x-component, a y-component, and a z-component. As such, each location coordinate may be a triplet (i.e., (x, y, z)).

[0048] At step 206, back end computing environment may generate an API that links user device 101 to database 124. API server 118 may generate an API that provides an interface to allow users of client device 101 to enter one or more parameters. The one or more parameters may act as input to a query against database 124. In some embodiments, API server 118 may notify client device 101 that an API is available. Client device 101 may access the functionality of API server 118 via application 114 executing thereon. Accordingly, users of client device 101 may submit one or more parameters directed to the generation of a heat map that illustrates particular "hot spots" or "dead zones" in the VR simulation based on, for example, the gaze and bodily locations of the user.

[0049] At step 208, back end computing environment 104 may receive a query from client device 101. Web server 116 may receive the query from client device 101 via the API accessed through application 114. The query may include one or more parameters directed to the generation of a heat map. In some embodiments, the query may include a level of granularity, i.e., a level of detail in which to generate the heat map. In other words, user of client device 101 may define the level of detail in which analysis server 120 will generate the heat map. Such level of granularity may be described, for example, in terms rectangular dimensions. For example, the user may define the level of granularity to be L x W x H, where L corresponds to length of a box (i.e., three-dimensional rectangle), W corresponds to width of the box, and H corresponds to height of the box. Accordingly, when analysis server 120 generates the heat map, analysis server 120 may segment the VR simulation location into a plurality of boxes with the dimensions specified in the query. Those skilled in the art may readily understand that a finer level of granularity (e.g., 1 cm x 1 cm x 1 cm) compared to a more obtuse level of granularity (e.g., 1 m x 1 m x 1 m) will provide a more detailed level of analysis.

[0050] At step 210, back end computing environment 104 may translate the received query into a query compatible with database 124. In some embodiments, analysis agent 120 may translate the received one or more parameters into a SQL query. In some embodiments, analysis agent 120 may translate the received one or more parameters into a query that is compatible with database 124.

[0051] Figure 3 is a flow diagram illustrating step 210 in further detail, according to one embodiment. At step 302, analysis server 120 may parse the query received via API. For example, analysis server 120 may identify one or more parameters transmitted from client device 101 to web server 116 via application 114.

[0052] At step 304, analysis server 120 may identify a level of granularity defined in the query. For example, analysis server 120 may parse the one or more parameters to identify the level of granularity defined by the user. The level of granularity defined in the query may be used by analysis server 120 in generating the heat map using the retrieved location coordinates from database 124.

[0053] At step 306, analysis server 120 may translate the received query to a query that is compatible with database 124. In some embodiments, analysis agent 120 may translate the received one or more parameters into a SQL query. In some embodiments, analysis agent 120 may translate the received one or more parameters into a query that is compatible with database 124.

[0054] Referring back to Figure 2, at step 212, back end computing environment 104 may query database 124 using the translated query (generated in step 210). For example, analysis server 120 may query database using the database-compatible query generated above to retrieve a plurality of location coordinates of the user during the VR session. In some embodiments, the query may request location coordinates related to a location of the user's gaze during the VR experience. In some embodiments, the query may request location coordinates related to a location of the user's body at various parts of the VR experience. In some embodiments, the query may request location coordinates related to one or more of the user's gaze, the position of the user's hands, the location of the user's head, the rotation of the user's head, the rotation of the user's hands, and the like.

[0055] At step 214, back end computing environment 104 may generate a heat map based on the retrieved location information. The heat map may be a graphical representation of data (i.e., location coordinates) where the individual values contained in a matrix are represented as colors. Each color in the heat map may correspond to a different level of concentration of location coordinates. Analysis server 120 may generate the heat map based on the level of granularity defined by the user. For example, analysis server 120 may split a location in the VR experience into a plurality of discrete segments. Each discrete segment may include one or more location coordinates. Analysis server 120 may generate the heat map based on a concentration of one or more location coordinates in each discrete segment. For example, analysis server 120 may count a number of location coordinates in each discrete segment, and assign each segment a concentration level based on the number of location coordinates contained therein. Those discrete segments with the highest number of location coordinates may be described as "hot spots," i.e., those locations that the user has viewed most frequently. Those discrete segments with the lowest number of location coordinates may be described as "cold spots," i.e., those locations that user viewed least frequently, or ignored.

[0056] At step 216, back end computing environment104 may present the heat map to the user. API server 118 may generate an API that allows user to view, access, manipulate the heat map via application 114 executing on client device 106. For example, web server 116 may notify client device 106 via application 114 that an API is available to access the generated heat map. Web server 116 may provide API to client device 106 such that user of client device 106 may access the heat map.

[0057] The generated heat map may provide an entity with a variety of information regarding the user's interaction with the VR environment. In some embodiments, the information may aid the entity in determining location of certain items in a real-world environment. For example, the entity may generate a VR environment in which several advertisements are placed. From the heat map, the entity may determine that certain locations in the VR environment are more appealing than others for advertisement placement. From the heat map, the entity may also determine that certain advertisements are deemed more desirable than others (e.g., those viewed less frequently based on the location coordinates). In another example, the entity may generate a VR environment in which an ATM is located. From the heat map, the entity may determine that users of the ATM frequently look towards a specific area in anticipation of a credit card slot being located therein. In both scenarios, the generated heat map based on the user's viewing of items in the VR environment may translate into the positioning (or re-positioning) of items in a real-world environment into more favorable locations.

[0058] Figure 4 is a block diagram 400 of a location in a virtual reality experiences, according to one embodiment. As recited above in conjunction with step 314, a heat map may be generated based on a level of granularity defined by the user. Illustrated in block diagram 400 are two sets of discrete segments based on different levels of granularity. The first set of discrete segments is block 402 and block 404. The second set of discrete segments is block 410 and block 412. The first set of discrete segments (block 402 and block 404) has a more obtuse level of granularity compared to the second set of discrete segments (block 410 and block 412). Each discrete segment may include one or more location coordinates 406 contained therein. As illustrated, block 404 includes a higher concentration of location coordinates than block 402, and therefore, would be illustrated differently on the heat map. Similarly, block 412 includes a higher concentration of location coordinates than block 410, and therefore, would be illustrated differently on the heat map.

[0059] Figure 5 is a block diagram illustrating an exemplary computing environment 500, according to some embodiments. Computing environment 500 includes computing system 502 and computing system 552. Computing system 502 may be representative of client device 102.

[0061] Processor 504 retrieves and executes program code 516 (i.e., programming instructions) stored in memory 506, as well as stores and retrieves application data. Processor 504 is included to be representative of a single processor, multiple processors, a single processor having multiple processing cores, and the like. Network interface 510 may be any type of network communications allowing computing system 552 to communicate externally via computing network 505. For example, network interface 510 is configured to enable external communication with computing system 552.

[0062] Storage 508 may be, for example, a disk storage device. Although shown as a single unit, storage 508 may be a combination of fixed and/or removable storage devices, such as fixed disk drives, removable memory cards, optical storage, network attached storage (NAS), storage area network (SAN), and the like.

[0063] Memory 506 may include application 512, operating system 514, and program code 516. Program code 516 may be accessed by processor 504 for processing (i.e., executing program instructions). Program code 516 may include, for example, executable instructions for communicating with computing system 552 to generate heat map based on parameters specified by the end user. Application 512 may enable a user of computing system 502 to access a functionality of computing system 552. The content that is displayed to a user of computing system 502 (e.g., generated heat map) may be transmitted from computing system 552 to computing system 502, and subsequently processed by application 512 for display through a graphical user interface (GUI) of computing system 502.

[0064] Computing system 552 may include a processor 554, a memory 556, a storage 558, and a network interface 560. In some embodiments, computing system 502 may be coupled to one or more I/O device(s) 572. In some embodiments, computing system 502 may be in communication with database 124.

[0065] Processor 554 retrieves and executes program code 566 (i.e., programming instructions) stored in memory 556, as well as stores and retrieves application data. Processor 554 is included to be representative of a single processor, multiple processors, a single processor having multiple processing cores, and the like. Network interface 560 may be any type of network communications enabling computing system 552 to communicate externally via computing network 505. For example, network interface 560 allows computing system 552 to communicate with computer system 502.

[0066] Storage 558 may be, for example, a disk storage device. Although shown as a single unit, storage 558 may be a combination of fixed and/or removable storage devices, such as fixed disk drives, removable memory cards, optical storage, network attached storage (NAS), storage area network (SAN), and the like.

[0067] Memory 556 may include analysis agent 562, operating system 564, program code 566, and verification agent 114. Program code 566 may be accessed by processor 554 for processing (i.e., executing program instructions). Program code 566 may include, for example, executable instructions configured to perform steps discussed above in conjunction with Figures 2-3. As an example, processor 554 may access program code 566 to perform operations for generating a heat map of user interaction in a VR simulation.

[0068] Analysis agent 562 may be configured to analyze movement of a user operating VR device 108 during a VR experience. In some embodiments, analysis server 562 may receive one or more parameters from client device 101 for analysis. For example, analysis server 120 may receive a plurality of coordinates corresponding to bodily movements of the user wearing the VR device 108 during the VR experience. In some embodiments, the plurality of coordinates may correspond to a location of a user's gaze during the VR experience. In some embodiments, the plurality of coordinates may correspond to a location of a user's head during the VR experience. In some embodiments, the plurality of coordinates may correspond to a location of a user's hands during the VR experience. Analysis server 120 may further receive one or more parameters to generate a query to execute against database 124. The query may be used to generate a heat map of user's gaze throughout the VR experience. For example, analysis server 120 may query database to determine one or more hot spots or dead zones in the VR simulation.
