Abstract: Technology is disclosed for enhancing the experience of a user wearing a see-through, near eye mixed reality display device. Based on an arrangement of gaze detection elements on each display optical system for each eye of the display device, a respective gaze vector is determined and a current user focal region is determined based on the gaze vectors. Virtual objects are displayed at their respective focal regions in a user field of view for a natural sight view. Additionally, one or more objects of interest to a user may be identified. The identification may be based on a user intent to interact with the object. For example, the intent may be determined based on a gaze duration. Augmented content may be projected over or next to an object, real or virtual. Additionally, a real or virtual object intended for interaction may be zoomed in or out.

Abstract: The technology provides for automatic alignment of a see-through near-eye, mixed reality device with an inter-pupillary distance (IPD). A determination is made as to whether a see-through, near-eye, mixed reality display device is aligned with an IPD of a user. If the display device is not aligned with the IPD, the display device is automatically adjusted. In some examples, the alignment determination is based on determinations of whether an optical axis of each display optical system positioned to be seen through by a respective eye is aligned with a pupil of the respective eye in accordance with an alignment criteria. The pupil alignment may be determined based on an arrangement of gaze detection elements for each display optical system including at least one sensor for capturing data of the respective eye and the captured data. The captured data may be image data, image and glint data, and glint data only.

Abstract: Corrugated fine mesh material is configured to be located overlying a gutter. The fine mesh material has an upper edge opposite a lower edge with the upper edge configured to fit beneath shingles on a roof adjacent the gutter. The lower edge is configured to be held to a lip at a forward edge of the gutter. The corrugations add strength to the material and collect water at troughs thereof where the collected water more readily forms droplets that fall down into the gutter. A lower strip is preferably provided to hold the lower edge of the mesh to a lip of the gutter. An upper strip is optionally provided which includes a tab which can fit beneath shingles to the roof. A barrier such as a bead of caulk can optionally be coupled to an underside of the corrugated mesh to further encourage water droplets to fall.

Abstract: A see-through head mounted-display and method for operating the display to optimize performance of the display by referencing a user profile automatically. The identity of the user is determined by performing an iris scan and recognition of a user enabling user profile information to be retrieved and used to enhance the user's experience with the see through head mounted display. The user profile may contain user preferences regarding services providing augmented reality images to the see-through head-mounted display, as well as display adjustment information optimizing the position of display elements in the see-though head-mounted display.

Abstract: The technology provides various embodiments for gaze determination within a see-through, near-eye, mixed reality display device. In some embodiments, the boundaries of a gaze detection coordinate system can be determined from a spatial relationship between a user eye and gaze detection elements such as illuminators and at least one light sensor positioned on a support structure such as an eyeglasses frame. The gaze detection coordinate system allows for determination of a gaze vector from each eye based on data representing glints on the user eye, or a combination of image and glint data. A point of gaze may be determined in a three-dimensional user field of view including real and virtual objects. The spatial relationship between the gaze detection elements and the eye may be checked and may trigger a re-calibration of training data sets if the boundaries of the gaze detection coordinate system have changed.

Abstract: The technology provides for adjusting a see-through, near-eye, mixed reality display device for alignment with an inter-pupillary distance (IPD) of a user by different examples of display adjustment mechanisms. The see-through, near-eye, mixed reality system includes for each eye a display optical system having an optical axis. Each display optical system is positioned to be seen through by a respective eye, and is supported on a respective movable support structure. A display adjustment mechanism attached to the display device also connects with each movable support structure for moving the structure. A determination is automatically made as to whether the display device is aligned with an IPD of a user. If not aligned, one or more adjustment values for a position of at least one of the display optical systems is automatically determined. The display adjustment mechanism moves the at least one display optical system in accordance with the adjustment values.

Abstract: Multiple assemblies are provided to overlie a gutter to preclude debris entry. Each assembly includes a mesh positioned upon an underlying substantially rigid support. The support has a tab which can reside beneath shingles and over other portions of the roof. A front edge is provided opposite the tab which rests upon a lip of the gutter when installed. A floor is located between the front edge and tab at a position slightly below a plane in which the tab and front edge are located. The mesh overlies the floor. Holes in the floor allow water which passes down through the mesh to be conducted through the floor and to fall down into the gutter. Ribs extend up from the floor to support the mesh and draw water off of the mesh. The mesh is corrugated into a plurality of crests and troughs which extend perpendicular to the ribs.
