Abstract:
1. An information system for providing information with respect to an eye, the system comprising: at least a first optical projection device configured to project infrared light into an environment in a field of vision of said eye; at least one camera configured to detect the infrared light reflected back from the environment; a sensor system configured to obtain information from the environment based on triangulation of the infrared light reflected back from the environment; spectacles including a holographic element disposed in front of said eye; and at least a second optical projection device configured to project light via the holographic element into said eye in correlation with the obtained information; wherein the holographic element has light-refracting characteristics at one or more discrete wavelengths along a partial area of a virtual ellipsoid disposed in front of said eye.
