Researchers from Stanford University have created a new tactile display that aims to allow the blind and visually impaired to access 3D printing and computer-aided design (CAD).

 .

The touch-based display can mimic the geometry of the 3D objects on a computer. The researchers say that while design tools empower users to create and contribute to society, the tools also limit those who can participate.

 .

The work is part of a larger effort in the lab of Sean Follmer, an assistant professor of mechanical engineering, to develop tactile displays.

 .

The display that the researchers have created looks a bit like the toys that many may have seen at retail stores. These toys tend to have lots of pins and can replicate whatever is pushed under them from behind, and the pins make a 3D shape on its surface. The Stanford device has a field of tall, rectangular pegs that move […]
