POLARIZATION COMPENSATION FOR WIRE GRID POLARIZER OF HEAD-MOUNTED DISPLAY SYSTEM
The present disclosure relates generally to techniques for improving the performance and efficiency of optical systems, such as optical systems for using head-mounted display system. The optical systems of the present disclosure may include polarized catadioptric optics, or “pancake optics,” which utilize a wire grid polarizer as a reflective polarizer. Wire grid polarizers may not perform uniformly over wavelength or over varying angles of incidence. To improve performance, a spatially varying polarizer is provided in the optical system that operates to provide polarization compensation for the wire grid polarizer so that the wire grid polarizer performs more uniformly over wavelength and/or over incidence angles (e.g., on-axis and off-axis). The spatially varying polarizer may be formed of a liquid crystal material, such as a multi-twist retarder.

Various embodiments are directed towards employing one or more physical sensors arranged on or in proximity to a video game player to obtain biofeedback measures that are then useable to dynamically modify a state of play of a video game. The sensors may be connected or even unconnected to the game player, replace, or otherwise augment traditional physical game controllers. The sensors gather various biofeedback measures and provide such measures to a biofeedback application programming interface (API). Before and/or during video game play, the video game queries the biofeedback API to request inferences about the game player's state of arousal. The response to the query is then used to modify the state of the video game play. Where the video game is a multi-player video game, biofeedback measures from other game players may also be obtained and used to further modify the state of the video game play.

Methods and systems are disclosed relating to a lens system that allows for simultaneous focus of near and far-away images with one pair of glasses, heads-up-displays (HUDs), and the like, without the need to move the user's eyes. This lens system may be used in a HUD application, for example, where the user may focus on a display lens that may be approximately one inch from the eye to view computer-generated information such as altitude, temperature, directions, and the like, and simultaneously view the individual's surroundings. The lens system may include a liquid lens that when modulated may vary from a near-focus state to a far-focus state rapidly by using an electrowetting or piezoelectric hydraulic actuator. This variable rate lens may be multiplexed at a rate that allows both near and far-away images to appear in focus simultaneously through the advantageous use of a user's persistence of vision.
