A post about a DIY olfactometer, Alex Kauffmann’s DIY scratch and sniff television. Talk about awesome. You scratch a sliced grapefruit image on the touch screen, put your nose close, and bingo, you smell grapefruit. Smelly TV inventor Kauffmann describes himself as an insight-based innovation consultant with a diploma in Interactive Telecommunications. You could also call him a high-tech tinkerer with a creative flair. He says that producing the videolfactory effect “required some clever sleight of nose.”
"First of all, I gave people clear visual cues. When you scratch a picture of chocolate, you’re much more likely to interpret the resulting smell as chocolate. I also made the screen respond to being scratched by fading, just as scratch-n-sniff stickers do after vigorous scratching."
