On November 6th, Stanford University researchers are developing a tactile-based "display" that can make 3D printing easier to use. The purpose of this research is to allow blind and visually impaired people to better perform 3D modeling and be able to use the display to create 3D printed objects. This tactile display, which looks a bit like a toy that many people see in retail stores, enables blind people to feel the shapes they create.

2.5D "tactile display"

The 2.5D "tactile display" is essentially an array of pins that can be raised and lowered to different heights, which is roughly the same as what we have seen in some "pin art" toys, so that blind people can feel the shapes they create.

In other words, you can create a 3D model to be printed and feel its actual state without relying on others to describe it.

This "display" can also rotate and magnify the object being displayed. In addition, there are other ingenious features, for example, when making a cup model, the top and bottom of the cup can be displayed next to the object.

Tactile-based displays are labeled 2.5D because the bottom of the display never changes shape, so it is not completely "three-dimensional".

The device was developed by researchers at Stanford University in collaboration with blind and visually impaired people. In terms of 3D printing (and general 3D modeling), it represents a new level of independence, so it does not require a visually-sighted facilitator. Make any given design.

The blind scientist Joshua Miele is a co-author of the device paper, and he helped develop the device. He commented: "This opens up the possibility that blind people are not only consumers of the advantages of manufacturing technology, but also the creators of them. We can create the tools we want or need in the 3D modeling environment-and hopefully Do it quickly."

The display was shown as a prototype at an exhibition held at the end of October and was part of the development of the "tactile display" led and developed by Sean Follmer, assistant professor of mechanical engineering at Stanford University.

The researchers ultimately hope that this tactile-based display will be implemented in a larger model that can represent shapes in more detail (using smaller pins for higher resolution) and is cheaper than current prototypes.

The accessibility of modern computing (including in the field of hardware) has made great strides, and it has indeed made considerable adjustments (including eye tracking) with software such as Windows 10 to ensure that the operating system becomes easier to operate.
