Here’s a perfect example of how accessibility matters and should demand our attention when designing and presenting information. “Images from NASA telescopes are jewels of the space program, marvelous to behold. But how do you behold them when you can’t see?”
NASA funded the recently released Touch the Invisible Sky: Exploring the Cosmos in Braille, a book which uses Braille, large type print, and tactile diagrams of celestial images observed by space telescopes Hubble, Chandra, and Spitzer to reveal the cosmos to the blind and seeing-impaired. I find this to be a inspirational and motivational story that reinforces our efforts in making information and experiences available (via the web in our case) to those with impairments.
