  • Patent number: 10108013
    Abstract: An augmented reality display system utilized in computing platforms such as wearable head-mounted display (HMD) devices includes a virtual reality display that is located in front of a user's eyes to provide a direct view of virtual world images. An optical periscope, comprising reflective or diffractive optical systems, is configured to provide an indirect view of the real world. By locating the virtual reality display (and its associated optical and electrical components) close to the user's eyes and within the user's direct line of sight, the field of view (FOV) of the virtual world is increased as compared with conventional indirect-view virtual reality displays. The optical periscope provides an FOV of the real world that would otherwise be obstructed by the positioning of the direct-view virtual reality display in front of the user's eyes.

Some other embodiments are directed to obtaining sets of eye measurement points from different users viewing the same scene. In another embodiment, the different sets of eye measurement points are mapped to a common coordinate system for reciprocal calibration In yet another embodiment, a scene transformation for mapping the common coordinate system to a coordinate system associated with the scene can be calculated by matching eye measurement points from the common coordinate system to interest points of the scene. The scene transformation is thereby calculated more accurately than individually calculated scene transformations, thereby providing a more accurate estimate of the gaze points.

  • Patent number: 9041793
    Abstract: A method of using a scanning microscope to rapidly form a digital image of an area. The method includes performing an initial set of scans to form a guide pixel set for the area and using the guide pixel set to identify regions representing structures of interest in the area. Then, performing additional scans of the regions representing structures of interest, to gather further data to further evaluate pixels in the regions, and not scanning elsewhere in the area.

  • Patent number: 9036872
    Abstract: An apparatus and method for authenticating a subject using the eye as an identifying biometric, in particular the shape of the cornea. An image projection device generates and projects an image of a pattern, of plural discrete points, onto at least a part of the cornea of the eye. An image capture device captures an image of the pattern of plural discrete points, after reflection from the cornea of the eye. A computer processor extracts data defining the locations of the discrete points in the captured image. The method steps are capturing an image of a pattern, made up of plural discrete points, after reflection from of the cornea of a subject; comparing the locations of the discrete points in the captured image against the locations of discrete points in a pattern of a reference image; and, authenticating the identity of the subject depending on the similarity of the comparison.
