Abstract: A display device including a display to generate a real image, and an optical system. The optical system includes a plurality of lenslets, each having one cluster of object pixels, where the assignation of object pixels to clusters may change periodically in time intervals. Each lenslet produces a ray pencil from each object pixel of its cluster which has waists laying close to a waist surface. The ray pencils are projected towards an eye position. The ray pencils are configured to generate a partial virtual image from the real image of its corresponding cluster. At least two of the lenslets cannot be made to coincide by a simple translation rigid motion. Foveal rays are a subset of rays emanating from the lenslets.

Abstract: A display device with one or more displays and an optical system with a plurality of channels arranged to generate an immersive virtual image from the a image, the virtual image comprising a plurality of image pixels, by each channel projecting light from the object pixels to a respective pupil range. The object pixels are grouped into clusters, each associated with a channel that produces from the object pixels a partial virtual image comprising image pixels. The clusters of at least two channels are substantially contained in opposite half-spaces defined by a plane passing by the imaginary sphere center. Each of the two channels comprises one surface on which the imaging light rays forming the partial virtual image suffer a last reflection before reaching the pupil range, where each surface is substantially contained in the opposite half-space containing their respective clusters.

Abstract: A display device has a display, operable to generate a real image, and an optical system. In the optical system are at least two free-form reflective surfaces, S I and S2. At least one of the reflective surfaces is convex in one direction at substantially all points of its optically active area. Light rays from the display are reflected on SI before they are reflected on S2. The reflective surfaces SI and S2 are arranged to generate a virtual image from the real image on the display, by projecting light from the display to an eye position. The field of view occupied by the virtual image as seen from the eye position is greater than 50 degrees in at least one direction, preferably the direction linking the two eyes of an intended user.

Abstract: A customer with a customer device performs a search for reviews of a particular software product of interest to the customer. The customer is then presented with entries from reviewers that have the same device as the customer, or a device on which the product is expect to run or operate in a manner similar to how it runs on the customer's device.
