Abstract: The invention relates to a method for determining at least one ophthalmological parameter of a subject, consisting of the subject's semi-pupillary distances, comprising observing the subject's two eyes using an eye tracking device (30) borne by the subject and determining the aforementioned parameter at least from this observation.

Abstract: Disclosed is an electronic device including a receiver of a piece of information sent by a gaze tracking device, which includes a marker forming a visual identification pattern, carried by a user moving in a real environment. In certain aspects, the received piece of information provides information about the direction of the user's gaze in a plane of reference of the gaze tracking device. At least one camera for acquiring an image of the marker, a memory for storing a digital representation of the environment in a plane of reference specific to the environment, and a processor configured so as, based on the piece of information of the image and the digital representation stored in the memory, to determine, in real-time, the direction of the user's gaze relative to the environment and/or the zone of the environment gazed at by the user may be provided herein.

Abstract: The present invention relates to a method for determining the direction in which a user is looking, which includes acquiring images of the eye, in particular by means of an optical sensor, the method including: a) a first processing of the images, yielding information on the orientation of the eye according to the observation of an area of the eye in which the aspect varies with the rotation of the eye; and b) a second processing of the images, yielding information on the kinematics of the eye by comparing at least two consecutive images; method in which information is generated relating to the direction in which the user is looking relative to the head of the user, at least according to the information supplied by the first and second processes.

Abstract: The present invention relates to an electronic device (100), including: a receiver of a piece of information (11) sent by a gaze tracking device (50) including a marker (1) forming a visual identification pattern and carried by a user (U) moving in a real environment (E), the received piece of information (11) providing information on the direction of the user's (U) gaze in a plane of reference of the gaze tracking device (50), at least one camera (30) for acquiring an image of the marker (1), a memory storing a digital representation of the environment (E) in a plane of reference specific to the environment (E), a processor configured so as, based on the piece of information (11) of the image and the digital representation stored in the memory, to determine, in real-time, the direction of the user's (U) gaze relative to the environment (E) and/or the zone of the environment gazed at (600) by the user (U).

Abstract: Luminescent composition injectable into a bird's egg characterized in that it comprises a luminescent compound forming a biomarker for a product having a vaccinal, therapeutic or diagnostic activity

Abstract: The present invention relates to a self-contained detection capsule (1) for insertion into a human or animal bodily canal, the capsule being free of a light source for illuminating the field of view, and comprising: an optical detector arranged to detect a light emitted by bioluminescence or chemiluminescence, without light excitation of the field of view of the optical detector by the capsule, and means for recording, processing and/or transmitting data relating to the light detected by the optical detector.

Abstract: The invention concerns novel 1,2-dioxetane derivatives of general formula (I) as defined in the description, capable of emitting a detectable luminescent signal, their use in a method for detecting and/or quantizing a physical, chemical or biological, in particular enzymatic, phenomenon, as well as a kit for implementing said method.

Abstract: The invention concerns an optical imaging device for a human or animal body, including: an optical sensing system, a drive system of at least one light collector from the optical sensing system, permitting modification of at least the position and/or direction, and a control system from the drive system, arranged so as to lead the light collector from the optical sensing system to at least one observation situation of at least one chosen region of the body to be examined, based on data concerning its topology.
