Testing 3-D Tactile Images
These images show people with visual impairments using their fingers to explore 3-D tactile representations of images taken by NASA's Hubble Space Telescope.
In these representations, stars, filaments, gas, and dust shown in Hubble images of the bright star cluster NGC 602 have been transformed through 3-D printing into textures, appearing as raised open circles, lines, and dots in the 3-D printout. These features also have different heights to correspond with their brightnesses. The tallest, and therefore brightest, features are a tight group of open circles, which represent the stars in the core of the cluster.
