The problem with scent
A few people are making smell o phones it would seem. I’ve seen this patent from Motorola and this dart-shaped prototype from Nokia.
However, there’s an issue with machine-made scent, apart from the fact it smells bad, of course. And that’s you can’t switch off a smell once it has been released into the air. Sound and light are both very controllable, but once a dose of scent has been released, tough, it hangs around.
So let’s hope these don’t catch on.
