Abstract: A method and associated systems for real-time subject-driven functional connectivity analysis. One or more processors receive an fMRI time series of sequentially recorded, masked, parcellated images that each represent the state of a subject's brain at the image's recording time as voxels partitioned into a constant set of three-dimensional regions of interest. The processors derive an average intensity of each region's voxels in each image and organize these intensity values into a set of time courses, where each time course contains a chronologically ordered list of average intensity values of one region. The processors then identify time-based correlations between average intensities of each pair of regions and represent these correlations in a graphical format. As each subsequent fMRI image of the same subject's brain arrives, the processors repeat this process to update the time courses, correlations, and graphical representation in real time or near-real time.

Abstract: Introduced herein are various techniques for displaying virtual and augmented reality content via a head-mounted display (HMD). The techniques can be used to improve the effectiveness of the HMD, as well as the general experience and comfort of users of the HMD. A binocular HMD system may present visual stabilizers to each eye that allow users to more easily fuse the digital content seen by each eye. In some embodiments the visual stabilizers are positioned within the digital content so that they converge to a shared location when viewed by a user, while in other embodiments the visual stabilizers are mapped to different locations within the user's field of view (e.g., peripheral areas) and are visually distinct from one another. These techniques allow the user to more easily fuse the digital content, thereby decreasing the eye fatigue and strain typically experienced when viewing virtual or augmented reality content.

Abstract: Introduced herein are various techniques for displaying virtual and augmented reality content via a head-mounted display (HMD). The techniques can be used to improve the effectiveness of the HMD, as well as the general experience and comfort of users of the HMD. An HMD may increase and/or decrease the resolution of certain areas in digital content that is being viewed to more accurately mimic a user's high resolution and low resolution fields of view. For example, the HMD may monitor the user's eye movement to identify a focal point of the user's gaze, and then increase the resolution in an area surrounding the focal point, decrease the resolution elsewhere, or both. Predictive algorithms could also be employed to identify which areas are likely to be the subject of the user's gaze in the future, which allows the HMD to present the regionally-focused content in real-time.
