摘要： An apparatus is disclosed for producing an optical display comprising an optical waveguide including a first diffractive part arranged to receive display light and to diffract the display light into an angle for guided propagation along the optical waveguide. A second diffractive part of the waveguide is optically coupled to the first diffractive part by the optical waveguide and is arranged to receive and to diffract light from the first diffractive part to an angle for output from the optical waveguide. Those external surfaces of the waveguide against which guided light reflects internally are coated with a meta-material having a refractive index of value less than 1.0 (one).

摘要： A method and apparatus are provided for controlling a display device to generate an image for viewing by a user on a display, the image being formed by one or more light having predetermined relative timings. Received image data define one or more light components of a feature to be displayed as an element in the image. Rate data are received, e.g. from an associated tracker system, indicative of a rate of change in orientation of the display relative to a direction of gaze of an eye of the user. The received rate data are used to determine a position on the display for displaying each of the one or more light components of the feature including determining any respective adjustment required to a determined position for the light component according to the received rate data and the predetermined relative timings. The determined position of each of the one or more light components is output to the display device for display of the light component at the respective determined position.

摘要： An apparatus for effecting a control action in respect of a function within a virtual or mixed reality system, the control action corresponding to a predefined bodily movement of an authorized user of said function, wherein an authorized user is defined by a predetermined criterion in respect of a selected body part and/or a passive device carried thereon. The apparatus comprises a detection module for detecting a predefined bodily movement; a multi-spectral imaging system for capturing spectral reflectance and/or emission data at a plurality of wavelengths in respect of said selected body part and/or the passive device carried thereon; and an analysis module for comparing at least a portion of the spectral data with data corresponding to an authorized user of said function to determine if said criterion is met, and outputting a signal to effect said control action only if said criterion is met.
