Blissmiss: I think that was the Smelling Nose dog. |
|
| |
is there a large population of smelling-challenged people out there? |
|

Rbl: I guess I'll know when they all come a-beating on my door, wanting to buy my SmelloBoost nose aids. |

As I spend much of my time around office environment smells, I'm hoping this thing's equipped with an 'off' switch. |

RayfordSteele: I guess you could programme it to produce pretty much any smell you wanted. You could turn it off, turn up the gain (Hey, can you smell gas ? ), or set it to "Rose Garden" or "Spring Meadow". The cartridges might have to come in different basic types like "urban" or "rural" .... |

Dysnomic is, I think, having a word retrieval problem. Hyposmia, a reduced smell function, affects 0.2% of the population. Paraosmia distorts the sense of smell, maybe something for RS. |

FarmerJohn; Many thanks for your correction. I wasn't quite sure about the correct term. Fortunately, the HalfBakery is well supplied with folk eager to correct such errors. |

Human beings have 1000 different smell receptors, each responding to a different molecule, so any attempt to synthesise smell based on proto-smells would fail (short of storing 1000 different chemicals, some of which would be highly volatile or even toxic). |
|
| |
Electronic noses, as I'm sure most people are aware, exist, but they are generally only sensitive to one particular molecule or a small range of molecules, which means the detection part of this would also have serious problems. The human nose is very sensitive and complex and still ill-understood compared to other senses. |

Potttedstu: Quite right: However, although the dynamic range of human hearing is 20 - 15000 Hz, the world gets by quite well on telephone lines which give a maximum 3.6 Khz bandwidth, ofthen a lot less. So this would not have the same "bandwidth" as the real nose, but it would help those who have problems. You might be able to get 100 protosmells in the cartridge. |

I like the idea of minor errors. "Say, Bill, this office could do with some ventilation." "Oh, I don't know, smells like wild roses to me!" "Bill, have you run out of putrid smell capsules for your nose again?" |

Delicatessens, bakeries and halfbakeries? |

You could concentrate scents by running a large volume of air over a chilled surface, which is then heated to release the adsorbed odors into a smaller volume of air. I can't see this being too practical for portable use, with the volumes required. |

In response to [pottsedstu]'s anno, this has been done before, with usb devices or some such thing for web surfing. I'll see if I can find a link. |
