Abstract
A method and device allowing a physiological signal, typically representative of brain activity, to be transcribed in the form of sensory signals perceptible to a human user, typically acoustic signals is provided. For this purpose, a physiological signal is acquired and then analysed in such a way as to detect therein patterns that are then parameterised in the time domain. One or more parameters of these patterns are used to determine one or more parameters of the generated sensory signals and/or to determine one or more parameters of temporal envelopes used to modulate the sensory signals. This method and device can be applied, in particular, to neuro-acoustic transduction.
Claims17
A physio-sensory transduction method comprising:
- an acquisition of a physiological signal of an organism using acquisition means;
- and
- a detection of one or more patterns in the physiological signal using detection means;
- for each pattern detected:
- an extraction of at least one pattern parameter from the pattern detected using extraction means;
- and
- a generation of a sensory signal associated with this pattern comprising:
- a determination of at least one parameter of the sensory signal as a function of the at least one pattern parameter using determination means;
- and
- a modulation of the sensory signal as a function of a temporal envelope associated with this pattern using modulation means, the temporal envelope having at least one envelope parameter determined as a function of the at least one pattern parameter.
A physio-sensory transduction device comprising:
- an acquisition means arranged and/or programmed in order to acquire a physiological signal from an organism;
- and
- a detection means arranged and/or programmed in order to detect one or more patterns in the physiological signal;
- an extraction means arranged and/or programmed in order to extract at least one pattern parameter from each pattern detected;
- and
- a generation system arranged and/or programmed in order to generate a sensory signal for each pattern detected, this generation system comprising:
- a determination means arranged and/or programmed in order to determine at least one parameter of the sensory signal as a function of the at least one pattern parameter;
- and
- a modulation means arranged and/or programmed in order to modulate the sensory signal as a function of a temporal envelope associated with this pattern, having at least one envelope parameter determined as a function of the at least one pattern parameter.
