Digital olfactory

A method of providing a digital olfactory solution involving a quantified assessment of a perceived smell intensity, the method comprising:

• processing, by a computer, an evaluation dataset resulting from performing direct distinction tests on a plurality of mixtures of an odorless material source of a primary smell with a second material source of a smell of interest added in different mixtures in different proportions;
• obtaining, by the computer, an intensity factor informative of the ratio of the second material source of the smell of interest necessary to distinguish the smell's presence in the mixture;
• and
• using the obtained intensity factor as a distinctiveness threshold for enabling the digital olfactory solutions.

A computing system configured to provide a digital olfactory solution involving a quantified assessment of smells similarity, the system comprising a computer configured to perform the operations comprising:

• processing computer, an evaluation dataset resulting from performing direct distinction tests on a plurality of mixtures of a first material source of a primary smell with a second material source of a secondary smell added in different mixtures in different proportions;
• obtaining a tolerance factor characterizing a pair of the primary smell and the secondary smell, wherein the tolerance factor is indicative of the proportion of the second material source required for its mixture with the first material source to be distinguishable from the primary smell alone;
• and
• using the obtained tolerance factor as a quantified similarity parameter for enabling the digital olfactory solution.

A non-transitory computer-readable medium comprising instructions that, when executed by a computing system comprising a memory storing a plurality of program components executable by the computing system, cause the computing system to providing a digital olfactory solution involving a quantified assessment of smells similarity, providing the digital olfactory solution comprising:

• processing an evaluation dataset resulting from performing direct distinction tests on a plurality of mixtures of a first material source of a primary smell with a second material source of a secondary smell added in different mixtures in different proportions;
• obtaining a tolerance factor characterizing a pair of the primary smell and the secondary smell,
• wherein the tolerance factor is indicative of the proportion of the second material source required for its mixture with the first material source to be distinguishable from the primary smell alone;
• and
• using the obtain tolerance factor as a quantified similarity parameter for enabling the digital olfactory solutions.
