Method of interaction by gaze and associated device

An electronic device, including:

• a receiver of a piece of information sent by a gaze tracking device including a marker forming a visual identification pattern and carried by a user moving in a real environment;
• the received piece of information providing information on 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 storing a digital representation of the environment in a plane of reference specific to the environment,
• 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,
• the environment being an enclosed space.

A gaze interaction system between one or more users and a real environment in which they are moving, the system including:

• a. a portable gaze tracking device identifiable by a visual marker, carried by each user,
• at least one electronic device, the at least one electronic device includes:
• a receiver of a piece of information sent by a gaze tracking device including a marker forming a visual identification pattern and carried by a user moving in a real environment;
• the received piece of information providing information on 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 storing a digital representation of the environment in a plane of reference specific to the environment,
• 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,
• the environment being an enclosed space.

A portable gaze tracking device including:

• a. one or more snapping and/or tightening systems, intended to fasten, at least part of the portable gaze tracking assembly, on a frame, and/or on one or more pieces of glass carried by the frame, for fastening on a user's head,
• b. an onboard computer making it possible to determine the direction of the user's gaze in the plane of reference of the head,
• c. a marker forming a visual identification pattern,
• the portable gaze tracking assembly forming a gaze tracking device, when it is fastened on the frame and/or on the piece(s) of glass.
