Abstract: In one embodiment, a method includes by one or more computing devices, accessing an image including a hand of a user of a head-mounted display at a first time. The method includes generating, from at least the image, a virtual object representation of the hand, defined in a virtual environment that includes at least one other virtual object. The method includes rendering a first image of the virtual environment comprising a first portion of the hand of the user at a first frame rate, and determining a second viewpoint of the user at a second time. The method includes rendering a second image of the virtual environment comprising a second portion of the hand of the user at a second frame rate. The method includes providing, to a set of light emitters of the head-mounted display, instructions to display the second image.

Abstract: Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.
