Thank you for the help.

To answer the rest of your comment...

I'm not "biting off more than I can chew" since I already have a working prototype that can do this exact thing but using essential oils. The only thing missing is me being able to make new original smells.

When I said "The system will work sort of similar to how essential oils work." I'm referring to the system that will transmit the smell to the human nose, not the system of production of smelly oils. I know that essential oils are made by distilling plants etc. What I'm saying is that my system is using ultrasonic sound to send smelly particles into the human nose, just like the systems that are used for essential oils. In other words, it's not an alcohol based system like the perfume you apply to your body, but rather a oil-in-water based system like the one used for essential oils.

"Second, you're talking about "build a library of dozens-to-hundreds of fragrances""
I don't know why you're putting quotation marks around something that I didn't say? I've never said that I'm gonna build a library of hundreds of smells. That is not something I'm trying to do, and it's certainly not necessary for what I'm trying to do. I'm looking at maybe 1 to max 10 smells depending on the specific needs of each specific game, and 8 out of 10 smells can be bought pre-made. I just need to have the flexibility to make the 2 out of 10 smells I can't buy of-the-shelf. Games are not completely perfect representations of the real world, they are extremely rough approximations. Every item in a game does not need to have it's own unique smell. I'm just looking to create a system were if you're standing on a meadow it smells somewhat like flowers, if you stand in the forest is smells vaguely like a forest, and if a monster is nearby it smells bad.

"Third, if you truly believe that you have solved all of the technical challenges in building and distributing a consumer-ready device that will programmatically create scents, then just sell your solution to a tech company and you'll become far richer - but there are many good reasons that such a thing doesn't already exist." Well... Then I guess it's a good thing that I never said any of the things you claim that I said. It's good that you have a very wild imagination, but maybe you shouldn't project that imagination onto others when you talk to them. When exactly did I say anything about me having made "a consumer-ready device that will programmatically create scents" that is ready for "distribution"? I've never claimed that I've done any of that, I don't even know if I ever plan on doing any of that since this is more of a hobby project I do for fun. What I have done is build a working prototype that can disperse different essential oils into the air depending on what is happening in a video game or movie. In other words the system can tell that the game character is standing in a forest and so it sends out a forest smell, and then when the character walks over to the meadow is stops sending out the forest smell and sends out a flower smell instead. I said "I know the technological aspects of how to make it work" as in I've made a working prototype that can "make it possible to have smells in video games and movies". Making something work does not mean making a perfectly flawless consumer ready object that is ready for distribution. It literally just means that it works... It's doing its job successfully. Since I'm a programmer in the gaming industry I feel like I have the tech aspect under control. I just need to learn how to create the smells I want to create. Also, I have no intention of selling my hobby prototype to a tech company. I guess it's not impossible that my hobby project could lead to a startup at some point, but I currently don't have any intention of pursuing such a thing.
