Tech helps blind ‘see’ computer images

A simple touch display for the visually impaired soon could provide access to computer-generated images.

The prototype tactile display is a set of 3,600 small pins, about 10 per inch, which “prints” an image by using an extendable pointer to raise selected pins into a line drawing of the image.

The device is being developed by the National Institute of Standards and Technology. The tactile display also would provide dramatic benefits in education.
