Smell sensing application opportunity

With cloud support, the complex applications such as smell analysis are now possible as mobile apps, I suppose.

Is it now possible to recerate smell at the application level using the cloud based smell recipes and some kind of a chemical cartridge ( like a color printer cartridge) having some basic chemicals capable of generating the required smell based upon recipes.

 

Can some App developer take this idea? It will smell a good business!!

Maybe we can finally get smellavision.

Identifying the Smell or Perfume is not yet possible; the author is just making a guess that with the application of the cloud and the sensors from Sensirion it would become possible to identify the smell or Perfume. Although it not so simple as it is written in the article. Still today no one has identified basic smells as we have identified basic colours. Through basic colours we can make any colour. But the same is not true for Smells.

Some interesting professional uses for this app, but I thought the concept of scratch-and-sniff was just plain silly. And I don't like those perfumed ads that sometimes get inserted into your paper or magazine.

Detecting Life Signs

Ever wonder what they are detecting on Star Trek when they detect life signs? I figure they are more like life odors. An electronic 'dog nose' is really the first step to building a real tricorder. It needs to smell the air. Your dog doesn't just smell people. It can identify which one is you. I think this is really cool technology.

@Kinnar,

 

That is my point. Why, until today we are not able to find the basic elelments of the smell?

We have found the basic elements of the color ( our visual sense). We have found the basic elements of the sound ( the audio frequency range). 

In the same way , if enough research effort is put, we should be able to identify the basic elements of smell , using which we should be able to reproduce any smell we want -  In my opinion.

With advance computing power available to us today, such analysis should be possible.

@prabhakar: We have found the basic elements of the color (our visual sense).

But it took us a long time to realize just how the color cones in our eyes worked to give us color vision.

Yes very true ! 

But I am talking about the production of the desired colors - depending upon the resolution available we can create required no of shades of colors as we want. We can aalso match a shade exactly  by a correct combination of basic colors.

Similarly even if we may not know how a partcular smell is perceived by our sensory system, we may be able to atleast reproduce a smell based upon its recipe ( the percentage of the basic components).  This will enable us to transmit the Smell alongwith picture , video. 

 

In Virtual reality context , this is the important area that we are still missing, in my opinion

Well ... sort of -- maybe -- it all depends. Most of us have three different types of color cones/receptors, so the mixing of CMYK pigments works well for us (similarly for mixing RBG light) -- but some people have four types of color receptors, and I think they do not get as good an experiance from the standard image generation techniquies we use. Check out the Tetrachromats, Pentachromats, Etc. topic in my paper on color vision.

Thank you Max for enlightening me on the intricacies of the Color Perception. I have yet not gone through the paper thoroughly but the browse thru itself gave a lot of insight.

This took a lot of work and "grew in the telling" ... so I woudl love to hear what you think about it when you get the time to dive in more thoroughly.

Well, I guess most things are at the most fundamental level -- but the higher-level mechanism is very interesting -- check out my paper on color vision.
