摘要： Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.

摘要： A head-mounted display device is disclosed that includes an at least partially see-though display, a processor, and a non-volatile storage device holding instructions executable by the processor to: select an image that corresponds to a physical object viewable by the user; display the image at a perceived offset to the physical object; in response to alignment user input, move a perceived position of the image relative to the physical object; output an instruction to provide completion user input when the image appears to align with the physical object; when the completion user input is received, determine the inter-pupillary distance of the user; and calibrate the head mounted display device based on the inter-pupillary distance.

摘要： Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). An inter-pupillary distance (IPD) value is determined from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having two fixed optics configured for a specific inter-pupillary distance. The position sensitive device is configured to produce a signal that corresponds to a distance between the two sighting fixtures. The images are warped with a processor to optimize display of the images with the two fixed optics for the determined IPD value.
