Definitions

  • the present disclosure is related to real-time adjustments of three-dimensional human representations for immersive reality applications. More specifically, the present disclosure is related to real-time gaze locking of avatars for social presence in virtual and augmented reality applications.
  • Virtual reality, augmented reality, mixed reality, and other immersive reality applications are becoming popular with users.
  • the realistic representation of human faces is a computationally intensive operation, often relayed to a remote server communicatively coupled with an enhanced reality headset either directly or via a mobile device paired with it.
  • these strategies may result in a time lag (e.g., latency) that creates awkward artifacts in the virtual world.
  • a time lag e.g., latency
  • One of the most notorious artifacts created by this latency is a retarded eye gaze on a transmitter/receiver avatar. This creates misunderstandings, expectations, and anxiety for two (or more) people trying to maintain a virtual conversation.
  • a system in a second embodiment, includes a memory storing multiple instructions, and one or more processors configured to execute the instructions to cause the system to perform a process.
  • the process includes to verify that a visual tracking of a transmitter avatar is active, and to adjust, in a receiver device, a gaze direction of the transmitter avatar to a fixation point, wherein to adjust the gaze direction of the transmitter avatar the one or more processors execute instructions to estimate a coordinate of the fixation point in a receiver frame at a later time, and rotate, in the receiver device, two gaze directions from a transmitter device to track the fixation point.
  • a non-transitory , computer-readable medium stores instructions which, when executed by a processor, cause a computer to execute a method.
  • the method includes verifying, in a receiver device, that a visual tracking of a transmitter avatar is active in a transmitter device, and adjusting, in the receiver device, a gaze direction of the transmitter avatar to a fixation point. Adjusting the gaze direction of the transmitter avatar includes estimating a coordinate of the fixation point in a receiver frame at a later time, and rotating, in the receiver device, two eyeballs of the transmitter avatar to point in a direction of the fixation point.
  • a system includes a first means to store instructions and a second means to execute the instructions to cause the system to perform a method.
  • the method includes verifying, in a receiver device, that a visual tracking of a transmitter avatar is active in a transmitter device, and adjusting, in the receiver device, a gaze direction of the transmitter avatar to a fixation point. Adjusting the gaze direction of the transmitter avatar includes estimating a coordinate of the fixation point in a receiver frame at a later time, and rotating, in the receiver device, two eyeballs of the transmitter avatar to point in a direction of the fixation point.
  • verifying that a visual tracking of a transmitter avatar is currently in place comprises identifying a conversation between the transmitter avatar and a receiver avatar.
  • verifying that a visual tracking of a transmitter avatar is currently in place comprises querying the transmitter device for a visual tracking signal.
  • verifying that a visual tracking of a transmitter avatar is currently in place comprises verifying that a value of a function of an angular difference between the gaze direction of the transmitter avatar and the fixation point is greater than a pre- selected threshold.
  • the one or more processors execute instructions to visually track the transmitter avatar with a gaze lock between the transmitter avatar and a receiver avatar, and to estimate the coordinate of the fixation point the one or more processors execute instructions to estimate a relative position between the transmitter avatar and the receiver avatar at the later time.
  • the one or more processors execute instructions to update the gaze direction at the later time to a new gaze direction received from the transmitter device when a distance between the gaze direction and the new gaze direction is greater than a preselected threshold.
  • the one or more processors further execute instructions to adjust ahead direction of the transmitter avatar based on the fixation point at the later time.
  • the one or more processors further execute instructions to update a world state at the later time based on a dynamic condition of the world state at a current time.
  • FIG. 1 illustrates a receiver and a transmitter participating in a virtual conversation using enhanced reality headsets configured for gaze locking in real time, according to some embodiments.
  • FIG. 4 illustrates world status parameters for a function to verify a gaze lock status of a transmitter avatar, according to some embodiments.
  • FIG. 5 is a flow chart illustrating steps in a method for gaze locking a transmitter avatar in real time for immersive reality applications, according to some embodiments.
  • FIG. 6 is a block diagram illustrating an exemplary computer system with which headsets and other client devices, and the method in FIG. 5, can be implemented.
  • embodiments as disclosed herein provide a receiver headset with mechanisms and procedures to adjust the gaze of a transmitter avatar locally, without having to communicate remotely with a mobile device, a server, and ultimately the transmitter headset.
  • techniques as disclosed herein may overcome a noise eye tracking detection system by estimating accurately a gaze fixation of a transmitter/receiver during a virtual conversation.
  • the eye tracking device can determine a gaze direction of receiver 101/transmitter 102.
  • Microphones 121 may record a speech 107-1 from receiver 101 or a speech 107-2 from transmitter 102 (hereinafter, collectively referred to as “speeches 107”).
  • architecture 10 transmits speeches 107 to the remote server 130 via network 150, where the entire capturing of the session may take place to be fed into virtual world 170.
  • each one of the devices illustrated in architecture 10 may include a memory storing instructions and one or more processors configured to execute the instructions to cause each device to participate, at least partially, in methods as disclosed herein.
  • an object of interest for receiver 101 may be the eyes or the face of avatar 112, the flower, or even a moving object at a distance (e.g. , a car, a train, a plane, another avatar, and the like). Accordingly, it is desirable to maintain gaze 115-1 focused on the flower for as long as the context of the conversation in virtual world 170 calls for. Reciprocally, it may be desirable to keep a gaze 115-2 of transmitter avatar 112 on the face (e.g., the eyes) of receiver avatar 111, within the context of the conversation that receiver 101 and transmitter 102 are having in virtual world 170.
  • the processing and transmission of datasets 103 incurs in an inherent latency of network 150. Moreover, errors are expected to occur as the data transmission involves at least three devices communicating over network 150 (e.g, headsets 100, mobile devices 110, and remote server 130). Accordingly, it is desirable that headset 100- 1 with receiver 101 makes a decision to adjust the gaze locking of transmitter avatar 112 before receiving an accurate rendition of such avatar from headset 100-2 through network 150.
  • This adjustment being a local change made by headset 100-1, is a real-time gaze locking that gives the conversation in the virtual world 170 a highly realistic impression.
  • headset 100-1 may be configured to analyze the context of the conversation from speeches 107, extracting meaning and intention and other more explicit or implicit content from the conversation between receiver and transmitter.
  • a user may interact with client device 110 via an input device 214 and an output device 216.
  • Input device 214 may include a mouse, a keyboard, a pointer, a touchscreen, a microphone, a joystick, a virtual joystick, and the like.
  • input device 214 may include cameras, microphones, and sensors, such as touch sensors, acoustic sensors, inertial motion units -IMUs- and other sensors configured to provide input data to a VR/AR headset.
  • input device 214 may include an eye tracking device to detect the position of a user’s pupil in a VR/AR headset.
  • Output device 216 may be a screen display, a touchscreen, a speaker, and the like.
  • Client device 110 may include a memory 220-1 and a processor 212-1.
  • Memory 220- 1 may include an application 222 and a GUI 225, configured to run in client device 110 and couple with input device 214 and output device 216.
  • Application 222 may be downloaded by the user from server 130 and may be hosted by server 130.
  • client device 110 is a VR/AR headset and application 222 is an immersive reality application.
  • client device 110 is a mobile phone used to collect a video or picture and upload to server 130 using a video or image collection application 222, to store in training database 152.
  • Memory 220-1 may also include an eye tracking module 242 that receives input from the eye tracking device in a headset and identifies a gaze direction of the headset user, in a virtual world (e.g., virtual world 170). Further, in some embodiments, eye tracking module 242 may also capture a pupil position and gaze direction of an avatar in the virtual world. Accordingly, eye tracking module 242 may correlate the gaze direction of a “receiver” avatar (e.g., a “local” avatar modeled on the user of client device 110) with the gaze direction of a “transmitter” avatar (e.g., an avatar that interacts with the receiver avatar and that is modeled on a user of a remote device 110).
  • a “receiver” avatar e.g., a “local” avatar modeled on the user of client device 110
  • a “transmitter” avatar e.g., an avatar that interacts with the receiver avatar and that is modeled on a user of a remote device 110.
  • the gaze direction of the transmitter avatar may be provided to client device 110 from the remote client device used by the transmitter, via server 130.
  • a network delay may result in an outdated signal received by client device 110 regarding the gaze direction of the transmitter avatar.
  • eye tracking module 242 may use a neural network tool 248 trained to predict a correct gaze direction of the transmitter avatar in the virtual world. In some embodiments, eye tracking module 242 is triggered to replace the current feed for the transmitter avatar gaze with a locally predicted gaze when a mismatch between the two becomes larger than a pre-selected threshold.
  • neural network tool 248 may be part of one or more machine learning models stored in database 152.
  • Database 152 includes training archives and other data files that may be used by eye tracking module 242 to accurately predict a gaze direction of the transmitter avatar.
  • at least one or more training archives or machine learning models may be stored in either one of memories 220, and client device 1 10 may have access to them through application 222.
