- Take one pair of Sony’s new 3D visor.
- Mount two very small digital video camera’s on the visor.
- Send the output of ONLY ONE of the cameras to a little Arduino circuit that warps the light spectrum in such a way that 500 nm is mapped to 560 nm (L-cones), 460 nm is mapped to 530 nm (M-cones) and 380 nm (UV) is mapped to 420 nm (S-cones).
- Display the unmodified output of one camera to one eye and the warped output of the other camera to the other eye.
- Wear the headpiece for a week or so to see if your brain is actually able to make sense of all the new information.
Apparently a fair number of females (around 1-2%) actually already have tetrachromacy so there must be some way of dealing with extra information which is not fully explained by current trichromatic or opponency models of vision. More here. The advantage of having different channels in different eyes is that you don’t have to worry about labeled lines in the retina itself.
It is frequently said, (although I haven’t found solid original research to back it up) that each cone type is able to discern around 100 gradations of intensity giving a maximum number of hue sensations of about 1 million (100*100*100). With six cones you would have the potential for 1012 discernable hue sensations. For those playing along at home, that’s a metric fuckload.
