    Abstract: A virtual eyeglass set may include a frame, a first virtual lens and second virtual lens, and a processor. The frame may mount onto a user's head and hold the first virtual lens in front of the user's left eye and the second virtual lens in front of the user's right eye. A first side of each lens may face the user and a second side of each lens may face away from the user. Each of the first virtual lens and the second virtual lens may include a light field display on the first side, and a light field camera on the second side. The processor may construct, for display on each of the light field displays based on image data received via each of the light field cameras, an image from a perspective of the user's respective eye.

    Abstract: A system for detecting and tracking a hover position of a manual pointing device, such as finger(s), on a handheld electronic device may include overlaying a rendered mono-chromatic keying screen, or green screen, on a user interface, such as a keyboard, of the handheld electronic device. A position of the finger(s) relative to the keyboard may be determined based on the detection of the finger(s) on the green screen and a known arrangement of the keyboard. An image of the keyboard and the position of the finger(s) may be rendered and displayed, for example, on a head mounted display, to facilitate user interaction via the keyboard with a virtual immersive experience generated by the head mounted display.

    Abstract: A computer-implemented method for dynamically adjusting rendering parameters based on user movements may include determining viewpoint movement data for a user viewing a rendering of a 3D model at a first time, determining a first level-of-detail at which to render the 3D model based at least in part on the viewpoint movement data at the first time and rendering the 3D model at the first level-of-detail. The method may also include determining viewpoint movement data for the user at a second time, wherein the viewpoint movement data at the second time differs from the viewpoint movement data at the first time. In addition, the method may include determining a second level-of-detail at which to render the 3D model based at least in part on the viewpoint movement data at the second time and rendering the 3D model at the second level-of-detail, wherein the second level-of-detail differs from the first level-of-detail.

    Abstract: Systems and methods to transition between viewpoints in a three-dimensional environment are provided. One example method includes obtaining data indicative of an origin position and a destination position of a virtual camera. The method includes determining a distance between the origin position and the destination position of the virtual camera. The method includes determining a peak visible distance based at least in part on the distance between the origin position and the destination position of the virtual camera. The method includes identifying a peak position at which the viewpoint of the virtual camera corresponds to the peak visible distance. The method includes determining a parabolic camera trajectory that traverses the origin position, the peak position, and the destination position. The method includes transitioning the virtual camera from the origin position to the destination position along the parabolic camera trajectory. An example system includes a user computing device and a geographic information system.
