Abstract

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.
