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

An orientation assistance system, comprising:

• means for acquiring a real or virtual visual environment;
• non-visual human-machine interface means comprising a haptic interface;
• and
• means for processing the digital representation acquired from a single acquisition of the visual environment to provide an electrical signal for controlling the haptic interface, the means for digital representation processing configured to periodically extract at least one pulsed digital activation pattern for a subset of spikes of the haptic interface, wherein:
• the haptic interface comprises a lumbar belt with an active surface of N×M spikes, where N and M are integers greater than or equal to 10;
• and
• the means for processing provides, for each single acquisition of the visual environment, a sequence of P activation frames for the spikes, where P is an integer between 2 and 15, each frame corresponding to the digital representation of the visual environment in an incremental depth plane, with the sequence of P activation frames being delivered in a burst for the single acquisition.
