How the iPhone helps a blind person...

. . . see?

From that blog post (via):

I have seen a lot of technology for the blind, and I can safely say that the iPhone represents the most revolutionary thing to happen to the blind for at least the last ten years. Fifteen or twenty years brings us back to the Braille ‘n Speak, which I loved in the same way, so have a hard time choosing the greater. In my more excitable moments, I consider the iPhone as the greatest thing to have ever happened to the blind, and it may prove so. . . . The touchpad offers the familiar next/previous motion which the blind need, since speech offers one-dimensional output. Adding the ability to touch anywhere on the screen and hear it adds a whole other dimension, literally. For the first time, the blind can actually get spacial information about something. In the store, Mom could say “Try that button” and I could. Blind people know what I mean. How many times has a sighted person said “I see an icon at the top of the screen?” Now, that actually Means something. . . .

The other night, . . . a very amazing thing happened. I downloaded an app called Color ID. It uses the iPhone’s camera, and speaks names of colors. It must use a table, because each color has an identifier made up of 6 hexadecimal digits. This puts the total at 16777216 colors, and I believe it. Some of them have very surreal names, such as Atomic Orange, Cosmic, Hippie Green, Opium, and Black-White. These names in combination with what feels like a rise in serotonin levels makes for a very psychedelic experience.

I have never experienced this before in my life. I can see some light and color, but just in blurs, and objects don’t really have a color, just light sources. When I first tried it at three o’clock in the morning, I couldn’t figure out why it just reported black. After realizing that the screen curtain also disables the camera, I turned it off, but it still have very dark colors. Then I remembered that you actually need light to see, and it probably couldn’t see much at night. I thought about light sources . . . . First, I saw one of my beautiful salt lamps in its various shades of orange, another with its pink and rose colors, and the third kind in glowing pink and red.. I felt stunned.

The next day, I went outside. I looked at the sky. I heard colors such as “Horizon,” “Outer Space,” and many shades of blue and gray. I used color [cues] to find my pumpkin plants, by looking for the green among the brown and stone. I spent ten minutes looking at my pumpkin plants, with their leaves of green and lemon-ginger. I then roamed my yard, and saw a blue flower. I then found the brown shed, and returned to the gray house. My mind felt blown. I watched the sun set, listening to the colors change as the sky darkened. The next night, I had a conversation with Mom about how the sky looked bluer tonight. Since I can see some light and color, I think hearing the color names can help nudge my perception, and enhance my visual experience. Amazing!
