Food Pill: When science-fiction becomes reality.
Hey there. I just joined this community, specifically to post the following:
I just woke up from a dream about a new type of photographic paper that could be developed into pictures where the colors were raised slightly from the surface and had different textures according to color and light density. Example: white = smooth & glossy to black being rough and nubbly. Red was slightly elevated and purple was more so and a little rougher in texture. The end result being that a blind person could "read" a photo with their fingers and (with training) be able to tell the color and shape of the object(s) the photograph depicted.
The dream was so vivid that upon waking I went online to see if anything out there was even close to this idea. I didn't find anything but then - I am not a photographer, so I wouldn't know where to look. Is there any way something like this would work? Is there a reactive emulsion or paper that might cause this kind of picture to develop?
Or am I barking mad, as usual?
Any ideas/comments/assistance will be muchly appreciated. Thanks!
It might be worth looking at Embossing techniques to get some kind of idea of how to raise surfaces but I am not sure there is a reactive paper out there that would do that kind of thing. Good luck in researching though, nothing is impossible :D
I don't think such photopaper is easy to make, but digitizing a photo, and printing it with some kind of textured ink might work.
That is an insane and VERY cool dream you had there. I love invention dreams, they are so intense and get you wanting to move and do things. As for the paper, I would like to say that nothing is impossible and I see some promise in such a paper. To me that doesn't seem so impossible, and if each pixel were read different way then yes to a trained person, a photo could be interpreted in an elaborate manner by touch.
Reminds me of this boy who went blind in his late teens and taught himself to paint by learning the texture differences between colours of paint he was using.
Sounds like it's time to introduce yourself to the Halfbakery

Interesting dream. :) As a blind person, I think it would be cool, but having worked with similar existing technology, can tell that for photos, it would still be difficult to "visualize" the image.
However, tactile graphic sytems do exist. Here is a page that although it doesn't have pictures does explain the technology and also the problem: http://dots.physics.orst.edu/tactile/tactile.html
Now, with regard to looking to the future, Scientific American had an article on haptic technology and maps you can touch:
Hope that helps.
i think its called airbrushed t-shirt topography
