Abstract
An orientation assistance system comprises means for acquiring a real or virtual visual environment, non-visual human-machine interface means and means for processing the digital representation of the visual environment in order to provide an electrical signal for controlling a haptic interface. The means for processing the digital representation periodically extracts at least one pulsed digital activation pattern for a subset of spikes of the haptic region. The haptic interface consists of a lumbar belt having an active surface of N×M actuators, where N and M are integers greater than or equal to 10. The processing means provides, for each acquisition of the visual environment, a sequence of P activation frames for the 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.
Core Innovation
An orientation assistance system acquires a real or virtual visual environment and provides a non-visual human-machine interface comprising a haptic interface. The haptic interface is a lumbar belt with an active surface of N×M spikes, where N and M are integers greater than or equal to 10. The system processes a digital representation acquired from a single acquisition to provide an electrical signal controlling the haptic interface.
For each single acquisition, the system periodically extracts at least one pulsed digital activation pattern for a subset of spikes of the haptic interface. The processing provides a sequence of P activation frames for the spikes, where each frame corresponds to the digital representation of the visual environment in an incremental depth plane. The sequence of P activation frames is delivered in a burst for the single acquisition.
Claims Coverage
The document includes two independent claims: an orientation assistance system and a processing method to control a haptic interface. The main inventive features relate to non-visual haptic control using a lumbar belt with an active surface of N×M spikes or actuators, and producing a burst of P activation frames per single visual acquisition, with each frame corresponding to an incremental depth plane.
Orientation assistance with depth-plane burst activation frames for a lumbar N×M spike belt
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 to provide an electrical signal for controlling the haptic interface. The haptic interface comprises a lumbar belt with an active surface of N×M spikes (N and M integers ≥ 10). For each single acquisition, the processing provides a sequence of P activation frames for the spikes, each frame corresponding to the digital representation in an incremental depth plane, with the sequence delivered in a burst for the single acquisition.
Processing digital representation into P incremental depth-plane activation frames for a lumbar N×M actuator belt burst
A method of processing a digital representation of a visual environment to control a haptic interface comprising a lumbar belt with an active surface of N×M actuators (N and M integers ≥ 10). For each single acquisition, the method calculates a sequence of P activation frames for the actuators. Each of the frames corresponds to the digital representation of the visual environment in an incremental depth plane, and the sequence of P activation frames is delivered in a burst for the single acquisition.
Across the independent claims, the central coverage is the translation of a single acquisition of a real or virtual visual environment into a digital representation that is converted into a burst-delivered sequence of P activation frames. Each activation frame corresponds to an incremental depth plane, and the haptic output is produced on a lumbar belt with an active surface of N×M spikes or actuators (N and M integers ≥ 10).
