Designers Lim Hyoseon, Kim Seungmo and Kim Suhyun won the 2009 Red Dot Award for this amazing concept device called the Readot. The device would essential translate two-dimensional digital images into tactile three-dimensional constructs for the visually impaired.
Readot uses a grid of pins that raise or lower in response to digital information corresponding to colors and shapes. In addition to the tactile component of the imagery, users would also be able to save the images or even print them out via PC. Hopefully, this brilliant piece of concept technology will see the light of day sooner rather than later.
