    摘要： Provided is a virtual image display device including: an image generator outputting a virtual image; a filter transmitting light in a first polarization state in the output virtual image; a multipath optical element guiding the transmitted light in the first polarization state; a first optical element arranged on a first side of the multipath optical element and allowing the guided light in the first polarization state and real-world light to pass therethrough; a second optical element arranged on a second side opposite to the first side of the multipath optical element and allowing the real-world light to pass therethrough; and a processor controlling the image generator, the first optical element, and the second optical element.

    摘要： A device for generating an image by projecting a plurality of source images onto this image according to a center of projection and a mapping. A source image is associated with a view direction according to the center of projection and the projection itself, the device comprises a memory associated with a processor configured for (1) obtaining a direction of interest for said image; and (2) for a pixel of the immersive image to generate, when a plurality of source pixels from the plurality of source images are projectable onto said pixel according to the center of projection and the mapping, one of these source pixels is selected to provide the considered pixel a color value. The selecting of the source pixel is performed according to the angle formed the direction of interest and the view direction of the source image the source pixel belongs to.

    摘要： Some embodiments involve obtaining access to a number of omnidirectional images which each represent a different viewpoint relative to the scene, and to metadata which is indicative of a physical relation between the respective viewpoint and a physical object present in the scene. Viewer data may be obtained which is indicative of a current physical relation between a viewpoint of the user and a same type of physical object in a current viewing environment of the user. An omnidirectional image may then be selected for display by comparing the viewer data to the metadata of the omnidirectional images.
    In other embodiments, an omnidirectional image may have been selected, e.g., from a number of omnidirectional images or by being the only available image, and the user may be instructed to assume a viewpoint in which the physical relation to the physical object in the user's current viewing environment corresponds to the physical relation as indicated by the selected image's metadata.

    摘要： Method for supporting a visual analysis (2) of a medical image data set (9), comprising:
    - providing a visualized medical image data set (10);
    - performing an analysis (2) of the visualized medical image data set by an user (5);
    - acquiring an eye orientation of the user during analysis by a device (16) for eye-tracking
    - respectively assigning the eye orientations (21) of the user (5) to regions (R1) of the visualized medical image date set (10);
    - assigning a control value (31) to a first region (R1) based on an intensity of eye orientations (21) directed to the first region and
    - providing an information (50) to the user (5) when the control value (31) is smaller and/or bigger than a threshold value (41) for the first region (R1).
