Abstract: A computerized method for correlating features of a user's motion in a VR-based exercise with specified populations includes the step of tracking a user's motion in a VR-based exercise with a hand controller. Based on a set of datapoints obtained from a sequence of positions of the hand controller, the method extracts a dynamic range of the user's motion. Based on the dynamic range, the method determines a velocity, an acceleration of the user's motion. The method determines the coefficient of variation for the velocity and the acceleration. From the acceleration and velocity data, the method calculates an initiation of the user's motion. The method calculates a combinatorial statistic from the coefficient of variation for the velocity ad the acceleration. The method determines a set of features of the user's motion represented by the combinatorial statistic that correlates to another combinatorial statistic associated with a specified population.

Abstract: Performance and capability improvements of computer devices that provide digital images of heatmap visualizations for datasets are provided via both systems and methods. A value-color spectrum is correlated to the dataset via a multi-pass rendering. The multi-pass rendering yields a two-channel mask, which is applied to a map to show the dataset in a heatmap visualization on that map, and may be continually used as the map is manipulated by a user. User interface tools are also provided to enable a user to specify a custom value-color spectrum, how the dataset is to be aggregated, the area of effect for a data point in the visualization, the strength of effect for a data point in the visualization, and which specifies how a dataset will be visually represented in a heatmap.

Abstract: Systems and methods are provided to improve map type data visualizations in which custom images are used as background against which datasets are visualized. In various examples, coordinate systems are automatically generated and applied to the custom image based on the positional data of the dataset. The custom image may replace a pre-existing background, and the plotting of the dataset may be automatically modified based on differences between the pre-existing background and the custom image. Aspects provide for enhanced user control of the map type visualization to further modify how datasets are plotted and how visualizations are presented. Example modifications include offsets and scales, which may be automatically determined and applied or set manually. In some examples, the custom image may be part of a set of image tiles, which are operable to provide various levels of detail from several viewing angles and heights.

Abstract: Methods for enabling hands-free selection of objects within an augmented reality environment are described. In some embodiments, an object may be selected by an end user of a head-mounted display device (HMD) based on detecting a vestibulo-ocular reflex (VOR) with the end user's eyes while the end user is gazing at the object and performing a particular head movement for selecting the object. The object selected may comprise a real object or a virtual object. The end user may select the object by gazing at the object for a first time period and then performing a particular head movement in which the VOR is detected for one or both of the end user's eyes. In one embodiment, the particular head movement may involve the end user moving their head away from a direction of the object at a particular head speed while gazing at the object.

Abstract: Systems and methods are disclosed for debugging the graphical output of a software program. This may be achieved both by displaying the graphical output of the software program at intermediary stages of the graphical rendering process, and by visually representing the interdependencies found within the software code of the program.
