Abstract: Described herein are a method, system and apparatus for mitigating motion sickness in a virtual reality (VR) environment. In an implementation, the system and apparatus can include a VR controller board, a processor and a VII headset. In an implementation, the processor and VR headset are an integrated device. In general, the method includes capturing measurements using the VR controller board. The measurements are indicative of user directional movements in a physical environment relative to the VR environment. In an implementation, the measurements relate to changes in the location of the center of mass of the user relative to the VR controller board. The processor uses the measurements to determine predetermined actions in the VR environment. The predetermined actions are then executed in the VR environment nearly simultaneous with the user directional movements in the physical environment.

Abstract: Systems, apparatuses, and methods for generating and utilizing sub-pixel sampling patterns on a processor are disclosed. In one embodiment, a processor includes at least multiple execution units and a memory. The processor generates sub-pixel sampling coordinates within each pixel of an image being rendered based on a rotated grid superimposed on the image. The processor also specifies an amount of rotation for the rotated grid. The processor utilizes the sub-pixel sampling coordinates for determining which locations to sample within the image being rendered. The sampling patterns generated based on these techniques enable using more complex and computationally efficient anti-aliasing resolve filters, resulting in higher quality images.

Abstract: Described is a method and apparatus to accelerate rendering of 3D graphics images. When rendering, the transformation matrix (or equivalent) used for projecting primitives is modified so that a resulting image is smaller and/or warped compared to a regular unmodified rendering. The effect of such transformation is fewer pixels being rendered and thus a better performance. To compute the final image, the warped image is rectified by an inverse transformation. Depending on the warping transformation used, the resulting (rectified) image will be blurred in a controlled way, either simulating a directional motion blur, location-dependent sharpness/blurriness or other blurring effects. By intelligently selecting the warping transformation in correspondence with the rendered scene, overall performance is increased without losing the perceived fidelity of the final image.

Abstract: Disclosed are a system and a method for interacting with electronic devices using a single-point gesture. A single point is selected in an image provided by a display associated with an electronic device. The selected point is continuously moved to generate a trajectory. A bending of the trajectory is monitored while moving the selected point. In response to the monitoring of the bending, the electronic device is operable to perform, based at least on the bending of the trajectory, a designated action. For example, the image is moved along the trajectory and while being moved the image is zoomed in when the trajectory bends clockwise and the image is zoomed out when trajectory bends counterclockwise. The scale of zooming is determined based on an area between a segment trajectory and a chord of trajectory found in a pre-determined time period or a pre-determined travel distance along the trajectory.

Abstract: Systems, apparatuses, and methods for performing hybrid anti-aliasing operations are disclosed. The hybrid anti-aliasing resolve operation combines multi-sampling anti-aliasing (MSAA) and post-processing anti-aliasing to generate higher-quality images in a computationally efficient manner. In one embodiment, a processor detects a request to perform an anti-aliasing resolve operation on an image stored in the memory. Responsive to detecting the request, the processor expands dimensions of the image and then filters the image with a post-processing anti-aliasing filter. After filtering the image, the processor performs an averaging of the image which becomes the result of the anti-aliasing resolve operation. Expanding dimensions of the image involves converting sub-pixels of the image into regular pixels. The processor can also rotate the image to align the sub-pixels into a vertical and horizontal grid pattern prior to filtering the image.

Abstract: Embodiments are directed towards using a color filtration system to generate multiple color images of a same single image that is displayed on a photo sensor plane to determine a lens adjustment position for a defined region of interest usable to automatically focus at least the defined region of interest using the single image. In one embodiment, the color filtration system employs a multiple color aperture filter and two single element lenses to generate multiple color images when an object within the single image is out of focus. In another embodiment, a metal dielectric interference filter is mounted directly in front of the photo sensor, to generate the multiple color images.
