Method and apparatus for acoustic or tactile presentation of chemical spectrum data

An apparatus, comprising:

• an input that receives at least one chemical spectrum, the at least one chemical spectrum comprising at least one value, the at least one value having at least a first component and a second component;
• a processor that:
• i) selects at least one periodic function for each first component of the at least one value of the at least one chemical spectrum,
• wherein the periodic function is selected by a single spectrum value or by a plurality of spectrum values;
• ii) modulates the at least one periodic function according to the second component of the at least one value;
• iii) composes the modulated periodic functions into at least one complex function;
• and
• a transducer that outputs each complex function.

Programmed media for use with a computer, the programmed media comprising a computer program stored on non-transitory storage media compatible with the computer, the computer program containing instructions to direct the computer to perform one or more of:

• a) acquire at least one chemical spectrum, the at least one chemical spectrum comprising at least one value, the at least one value having at least a first component and a second component;
• b) select at least one periodic function for each first component of the at least one value of the at least one chemical spectrum,
• wherein the periodic function is selected by a single spectrum value or by a plurality of spectrum values;
• c) modulate the at least one periodic function according to the second component of the at least one value;
• d) compose modulated periodic functions into at least one complex function;
• and
• e) output each complex function to an acoustic device, a tactile device, or a combination thereof.
