    Abstract: A method for improved compression and filtering of images for foveated transport applications. The improvements including calculating along at least one axis of the full-resolution image data set, the distance from the foveal point to edges of full-resolution image data set, calculating the distance from each edge of the full resolution data set to the closest point on a foveal region surrounding the foveal point, calculating the distribution of available space in the adjacent peripheral regions of the image using a compression parameter, and calculating a compression curve wherein the compression of both adjacent peripheral regions is such that neither side of the adjacent peripheral regions are compressed more than the other.

    Abstract: A method for mapping an input device to a virtual object in virtual space displayed on a display device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include, based at least in part on the gaze direction being directed to a virtual object in virtual space displayed on a display device, modifying an action to be taken by one or more processors in response to receiving a first input from an input device. The method may further include, thereafter, in response to receiving the input from the input device, causing the action to occur, wherein the action correlates the first input to an interaction with the virtual object.
