Title
(EN) METHOD AND APPARATUS FOR ACOUSTIC OR TACTILE PRESENTATION OF CHEMICAL SPECTRUM DATA
(FR) METHODE ET APPAREIL DE PRESENTATION ACOUSTIQUE OU TACTILE DE DONNEES DU SPECTRE CHIMIQUE
Abstract
(EN)

An apparatus for presenting a chemical spectrum to a human user in an audible
and/or
tactile format comprises an input that receives at least one chemical
spectrum, a processor, and at
least one transducer that produces the audible and/or tactile output. The
processor identifies a
first component and a second component of at least one value of the at least
one chemical
spectrum, selects at least one periodic function for each first component, and
modulates the at
least one periodic function according to the second component. Modulated
periodic functions
are composed into at least one complex function which is output to the at
least one transducer to
produce the audible and/or tactile output. The chemical spectrum may comprise
data obtained
from a sample using mass spectrometry, Raman spectroscopy, or the like.
