ORIENTATION ASSISTANCE SYSTEM COMPRISING MEANS FOR ACQUIRING A REAL OR VIRTUAL VISUAL ENVIRONMENT, NON-VISUAL HUMAN-MACHINE INTERFACE MEANS AND MEANS FOR PROCESSING THE DIGITAL REPRESENTATION OF SAID VISUAL ENVIRONMENT.

WIPO Patent Application WO/2023/147996

A1

The present invention relates to an orientation assistance system comprising means for acquiring a real or virtual visual environment, non-visual human-machine interface means and means for processing the digital representation of said visual environment in order to provide an electrical signal for controlling a haptic interface, said means for processing the digital representation consisting in periodically extracting at least one pulsed digital activation pattern for a subset of spikes of said haptic region, characterised in that said haptic interface consists of a lumbar belt having an active surface of NxM actuators, where N and M are integers greater than or equal to 10, and in that said processing means provides, for each acquisition of said visual environment, a sequence of P activation frames for said actuators, where P is an integer between 2 and 15, preferably between 5 and 10, each of the frames corresponding to the representation of the environment in an incremental depth plane.
