We have screens for display, speakers and headphones for sound, eventually VR controls will be so advanced that they could simulate touch and feel, but why are there still no devices that simulate smell?

BBBBRRRRRRAAAAAAAAAAAAAAAP

There are but they're goddamn useless and pieces of shit

it was tried once back in 99. it failed.

Because Jow Forums hackers could gas kikes

Think about it, do you REALLY use smell in real life? I'm not talking about meme stuff like walking through a field and smelling flowers or something. You basically don't use your smell and don't even realize it, it's completely useless. Eventually humans will evolve and lose the ability to smell things anyway.

Smell is implicitly tied to memory. Without it, memories are about 1/10th the strength. This has been scientifically established through numerous experimental double blind studies. Even the rats show better maze response. The meme smells, make the feels more reals.

Didn't "South Park: Fractured but Whole" have this?

>simulates the smell of hydrogen cyanide for OP
You can thank me later.

Because footfags are ALREADY insufferable, could you imagine the "imagine the smell" posts with smellovision

Imagine a virus that hijacks your olfactory generator device and starts emitting rotting corpse smells.

Smell is absurdly complex. It's difficult to synthesize specific odors using generalized equipment. You'd end up having to store dozens of cartridges of base molecules to make it work reasonably well. What a pain in the ass that would be to maintain.
Then there's the matter of lingering odors. If you just pump chemicals into the room, they're going to hang around. Eventually it's going to be like a candle store with the assault on your nostrils. So to get it right, you need to be able to deliver a specific scent for an arbitrary amount of time, then clear it quickly to feed another distinct one. The only way I can see this working is with a direct nose feed using plugs. Who the fuck would wear those?

If you're emitting base chemicals, what's stopping rogue software from literally emitting mustard gas?

>Taste and smell are separate senses with their own receptor organs, yet they are intimately entwined. Tastants, chemicals in foods, are detected by taste buds, which consist of special sensory cells. When stimulated, these cells send signals to specific areas of the brain, which make us conscious of the perception of taste. Similarly, specialized cells in the nose pick up odorants, airborne odor molecules. Odorants stimulate receptor proteins found on hairlike cilia at the tips of the sensory cells, a process that initiates a neural response. Ultimately, messages about taste and smell converge, allowing us to detect the flavors of food.

hackers can TURN YOUR SMELLOTRON INTO A BOMB and BLOW YOUR NOSE TO SMITHEREENS

DON'T CLICK THAT IT MAKES MUSTARD GAS

Its not a means to interface with the computer. Immersion is not important unless your a gaymer.

is this the most retarded thing that has ever been posted on Jow Forums?

what if you used software to light up the brain areas associated with smell?

sound and vision are very simple senses that give us a lot of information about what is more or less just very simple information - the rate of air vibration and the direction and intensity of photons. you can mathematically describe those things very simply and it is very simple to recreate them in a lower resolution - which how compression and pretty much the entirety of digital communication works

smell can't be described with math and even if you had the raw information of the mollecule being sensed you would not have any clue what it would smell like, which is not at all like how vision or sound work

That's not how the API would work. You'd get to pick between the supported scents, and the ability to mix compiled scents, but not the ability to specify arbitrary chemical reactions using the base reagents. It wouldn't even be able to do that, realistically. Reaction modules would be limited to producing a fixed set of outputs based on what you feed in. Making a machine that can perform arbitrary reactions with more than a couple reagents is kinda an open problem. I'm not aware that any exists.
The worst that can happen is conflicting odors are used, which might be disorienting (like candle shops usually are).

How would you do this with current technology? We can't, yet.

wow what a great thread
