By utilizing computer and modern software can be a chore to commence with for visually challenged, but fundamentally visual talks like 3D design are even more difficult.
The team of Stanford University is working on a way to display 3D information, like CAD or modeling program, using ‘2.5D’ display made up of pins that can be raised or lowered as sort of tactile pixels.
The research project, association between graduate student Alexa Siu, Joshua Miele and chief of Sean Follmer, is has an intention to explore avenues by which visually impaired and blind can achieve tasks without the aid of a sighted helper.
The device is essentially a 12X24 array of thin columns with rounded tops that can be separately told to rise anywhere from a fraction of inches above the plane, emerge in the shape of 3D objects quickly enough to amount to real time.
“It opens up the possibility of blind people being, not just consumers of the advantages of fabrication technology, but agents in it, carving our own tools from 3D modeling environments that we would want or need- and having some hope of doing it in timely manner,” explained Miele, who is himself blind.
Siu calls the device ‘2.5D’, since of course it show the object the whole object floating in midair. But it’s an easy way for someone who can’t see the screen to understand the shape it’s displaying. The resolution is limited, but that’s a disadvantage shared by all tactile display- which it should be noted are extremely rare to begin with and often are very exorbitant.
The field is moving forward, but too slowly for some, like this crew and the parents behind the BecDot, an inexpensive Braille display for kids and other tactile displays are being pursued as possibilities for communication in virtual environments.
The toy named BecDot that helps preach visually challenged kids to read braille.
Learning braille is a skill, like most of the people can be learned at any early age by those who are in dire need of it.
But toddlers with vision impairment often have a couple of options, lagging behind their peers on academical and social grounds. BecDot is a toy curated by the parents facing that challenge that teaches kids braille in a fun, simple way, and is vigorous and affordable.
Getting an understanding of 3D shape, its designing and viewing, means rotating and shifting it which is at times difficult to view in non-visual ways.
But real-time display like this can transform the shape and also makes formation of complex shape easier.
A lot of time would be required to commercialize the device, as only the working prototype has been designed. The team is planning to decrease the size of the pins, which would result in better resolution of the display.
