Abstract: Systems and methods of converting visual content for display on a virtual display system include extracting depth information from input visual content and formatting the input visual content and the depth information. The virtual display system may produce virtual images that are multifocal virtual images. The conversion of the input visual content into the multifocal virtual images may be impacted by properties of the human vision system, physical modeling of the input visual content, user input or sensory data, or generative content.

Abstract: In some embodiments, generative systems are physical mechanics and hardware apparatus to generate display content and include an input receiver module, a graphics processor module, and an output module. In some embodiments, the input receive module converts or splits a video input signal to provide a video input stream for the graphical processing module, which includes one or more processing units. The graphics processor module extracts both the graphical input content and the metadata of the input stream, operates on said information, and outputs the result to the output module, which emits an output signal for display on a display system. In some embodiments, the graphics processor module uses a generative function or a computer vision function. In some embodiments generative system is a standalone device to mediate and infer visual content between a computational system and a display system.

Abstract: Systems and methods are described for generative or extended display experiences with generative functions. In some embodiments, a display system is a virtual display system. A plurality of input streams is generated and received by a function module, which operates on the input streams to produce modified display content. In some embodiments, the function module implements an artificial intelligence module. In some embodiments a user modifies the display content through user input, which includes eye gaze.
