摘要:
The invention relates to an information system comprising a signal detection device (1751) which detects signals reflected back by at least one eye having a retina; a visual field detection device which detects visible light in a visual field associated with the retina, without detecting a ghost image of the retina; an information device; and an output device which co-operates with the information device to provide information according to the detected light and in correlation with the detected signals.
摘要:
In a device or a method for determining the direction of vision of an eye, a starting point or a final point of a light beam reflected by a part of the eye and detected by a detector system, or of a light beam projected by a projection system onto or into the eye two-dimensionally, describes a pattern of a scanning movement in the eye. The inventive method uses a displacement device that guides the center of the pattern of movement into the pupil or macula center of the eye, and a determination device that uses the pattern of movement of the scanning movement to determine the pupil center or macula center.

In an information system and a method for providing information in correlation with light that is incident on an eye, a pair of spectacles includes a holographic element that is supported in front of the eye of a wearer of the spectacles. An optical scanning device detects light that is incident on the eye via the holographic element.
