Abstract: A system and related methods for visually augmenting an appearance of a physical environment as seen by a user through a head-mounted display device are provided. In one embodiment, a virtual environment generating program receives eye-tracking information, lighting information, and depth information from the head-mounted display. The program generates a virtual environment that models the physical environment and is based on the lighting information and the distance of a real-world object from the head-mounted display. The program visually augments a virtual object representation in the virtual environment based on the eye-tracking information, and renders the virtual object representation on a transparent display of the head-mounted display device.

Abstract: Various embodiments are disclosed that relate to the presentation of images of shadows cast over a real-world background by images of objects displayed on a see-through display. For example, one disclosed embodiment provides a method of operating a display device having a see-through display screen. The method comprises displaying on the see-through display screen an image of an object, and while displaying the image of the object, displaying an image of a shadow cast by the object onto the background scene by acquiring an image of a background scene, determining a location of the shadow in the image of the background scene, rendering an enhanced image of the background scene by increasing a relative brightness in a region adjacent to the shadow compared to a brightness within the shadow, and displaying the enhanced image of the background scene.

Abstract: Embodiments are directed to a pneumatic off-road tire having an inner shoulder, an outer shoulder and a tread therebetween. The tread has a central axis and includes a plurality of generally curved first grooves. Each first groove has a first end disposed near the outer shoulder and a second end disposed near the inner shoulder so that each first groove crosses the central axis. The first end is spaced circumferentially from the second end. A plurality of second grooves, each connecting the second end of a first groove to a first end of another first groove, are included. The first and second grooves define a cascading repetition of tread blocks. Chamfers are defined on certain corners of the tread blocks that are adjacent to the first grooves and that expose a tread block wall following the chamfer, relative to a rotation of the tire, to an off-road contact surface.
