  • Patent number: 12602878
    Abstract: A method for testing overlay of a virtual environment to a physical environment that includes generating a target to identify a virtual reference point in a virtual environment. The virtual reference point corresponds to a physical element in a physical environment. A virtual reference point position is recorded. The target is projected on the virtual reference point to a user through a head mounted display. The user identifies the target. The method can continue with projecting the physical environment to the user, and monitoring a physical pointer of the user that is contacting the physical element in the physical environment that corresponds to the virtual reference point. A virtual pointer may be generated in the virtual environment corresponding to the physical pointer of the user. A vector can then be measured characterizing a difference between a position of the virtual pointer and the virtual reference point position.

  • Patent number: 12517356
    Abstract: A method, apparatus, system and medium are provided. The method includes generating a virtual environment of a test scenario for a head mounted display (HMD) mounted to a model head on a test stand, where the virtual environment includes at least a first shape and a second shape, moving the model head on the test stand, receiving, by a data acquisition system (DAQ), from an accelerometer mounted on the model head, changed signaling indicating the movement of the model head, updating the virtual viewpoint of the HMD based on the movement of the model head, displaying the updated virtual viewpoint in the HMD, receiving, by the DAQ, from a light sensor mounted on the model head, changed signaling based on displaying the updated virtual viewpoint in the HMD, and generating, by the DAQ, a data file encoding the signaling from the accelerometer and the light sensor.

  • Patent number: 12452401
    Abstract: Example methods, apparatuses, and computer-readable media are provided. Example methods include generating a virtual environment including a first shape and a second shape in a virtual viewpoint, the first shape in front of the second shape. The second shape adjusts as the virtual viewpoint adjusts, and is offset from the first shape along a test axis. The first shape is affixed to the virtual viewpoint. The virtual viewpoint is configured to adjust in response to movement of a HMD. The method includes moving a position of the virtual viewpoint with respect to the second shape in response to the movement. The method includes recording reference data associated with moving of the position of the virtual viewpoint. The method includes generating a positional displacement vector by comparing reference data of the second shape with reference data of the first shape, and determining a HMD movement tracking error based on the vector.
