In the prior art, common observation devices (1) as surgical microscopes, endoscopes (3) or microscopes (5) have the disadvantage that it is ambiguous whether a detected intensity (97) is due to fluorophore (29) concentration or due to optics setting parameters (73). The inventive method overcomes said disadvantages by automatically adjusting at least one exposure control parameter (83) if at least one optics setting parameter (73) is changed.

    Abstract: A method, computer program product, and visual display apparatus include a processor(s) obtaining, via a camera device, a unique identifier, wherein the unique identifier was captured by the image capture functionality of the camera device during a given temporal period. Based on the unique identifier, the processor(s) determines an application, where a graphical user interface of the application, when rendered through a client during the given temporal period, displayed the unique identifier (and was captured by the camera device). The processor(s) obtain, from the camera device, identifying data relevant to a user associated with the camera device. Based on the unique identifier and the identifying data, the processor(s) provides content targeted to the user.

  • Publication number: 20190227308
    Abstract: A light guide unit has a cold mirror unit to guide display light toward a projection window. In an XYZ color system, a wavelength region between a wavelength at which a value of a color matching function Z is maximum and a wavelength at which a value of the color matching function Y is maximum is a first wavelength region, and a wavelength region between a wavelength at which a value of a color matching function Y is maximum and a wavelength at which a value of a color matching function X is maximum is a second wavelength region. A minimum reflectance of the cold mirror unit to the display light takes a minimum value among reflectances of the respective wavelengths in a corresponding wavelength region. The minimum reflectance in the second wavelength region is larger than the minimum reflectance in the first wavelength region.

    Abstract: Systems and methods are provided for task-based modification of visual media in a heads-up display. An example system includes a heads-up display assembly configured to be worn by a user, the heads-up display assembly including a head mount and a presentation generator configured to display visual media to the user. The example system further includes a memory, and a processor configured to interface with the presentation generator and the memory. The processor identifies a current task associated with the user, and obtains a focal distance at which the visual media is to be displayed to the user during the performance of the current task. The processor causes the presentation to display the visual media at the obtained focal distance during performance of the current task.

    Abstract: A waveguide display includes a substrate having two opposite surfaces, and a slanted grating at a first surface of the two opposite surfaces of the substrate. The slanted grating includes a plurality of ridges and is characterized by a grating period in one direction. The plurality of ridges is tilted at a slant angle with respect to a surface normal of the first surface and is characterized by a height. The height of the plurality of ridges, the grating period, and the slant angle are configured to cause destructive interference between ambient light diffracted by the slanted grating. In some embodiments, a difference between the height of the plurality of ridges and an integer multiple of the grating period divided by the tangent of the slant angle is less than a threshold value.
