Determining combinations of odors to produce a target olfactory pleasantness

1. A method comprising the steps of:

receiving a signal comprising a target olfactory pleasantness;

determining one or more combinations of odors which produce the target olfactory pleasantness;

selecting a given one of the combinations of odors; and

utilizing the given combination of odors to select amounts of respective ones of two or more available constituent odors such that the selected amounts of the available constituent odors produce a given odor with the target olfactory pleasantness;

wherein the target olfactory pleasantness comprises a value indicative of a quality of the given odor in a defined space of odors; and

wherein the receiving, determining, selecting and communicating steps are performed by at least one processor device.

2. The method of claim 1 , further comprising converting a source odor into the signal.

3. The method of claim 2 , wherein the given odor and the source odor are different from one other.

4. The method of claim 2 , wherein converting the source odor into the signal further comprises selecting a given encoding scheme to convert the source odor into the signal, the given encoding scheme being selected based at least in part on a number of bits required to transmit the signal.

5. The method of claim 1 , wherein the given combination of odors comprises a set of constituent odors, each of the constituent odors having an olfactory pleasantness value indicative of a quality of that constituent odor in the defined space of odors, and wherein an olfactory pleasantness value of the given combination of odors comprises a linear combination of the olfactory pleasantness values of the constituent odors in the set.

6. The method of claim 1 , wherein the target olfactory pleasantness is a given one of a set of discrete pleasantness levels and wherein the given odor has the given pleasantness level.

7. The method of claim 1 , wherein determining combinations of odors is based at least in part on a set of available constituent odor resources.

8. The method of claim 7 , wherein selecting the given combination of odors is based at least in part on a total amount of constituent odor resources in the one or more combinations of odors.

9. The method of claim 7 , wherein selecting the given combination of odors is based at least in part on a current availability of constituent odor resources.

10. The method of claim 7 , wherein selecting the given combination of odors is based at least in part on a total cost of constituent odor resources in the one or more combinations of odors, wherein each of the available constituent odor resources has an associated cost.

11. The method of claim 7 , wherein selecting the given combination of odors is based at least in part on two or more of:

a total amount of constituent odor resources in the one or more combinations of odors;

a current availability of constituent odor resources; and

a total cost of constituent odor resources in the one or more combinations of odors, wherein each of the available constituent odor resources has an associated cost.

12. The method of claim 1 , wherein the signal comprises a set of coordinates on a simplex plot of odors and wherein odors on the simplex plot are associated with respective olfactory pleasantness values.

13. The method of claim 12 , wherein the set of coordinates comprises a partition of the simplex plot.

14. The method of claim 12 , wherein the olfactory pleasantness values associated with one or more corners of the simplex plot have respective certainties associated therewith, and wherein selecting the given combination of odors is based at least in part on the respective certainties of constituent odors on the simplex plot.

15. The method of claim 1 , wherein selecting the given combination of odors comprises:

selecting a first combination of odors based on a first store of constituent odors available for producing the given odor with the target olfactory pleasantness at a first location; and

selecting a second combination of odors different than the first combination of odors based on a second store of constituent odors available for producing the given odor with the target olfactory pleasantness at a second location different from the first location.

16. The method of claim 1 , wherein the signal further comprises a scent category and wherein determining the one or more combinations of odors comprises determining one or more combinations of odors which produce the target olfactory pleasantness in the scent category.
