It is something new for that there is braille computer. I just visit a forum and I read article about braille computer, I think it is interesting information because sightless people can get information through internet like normal people just with different version so I want to share in here too.
An industrial designer Jonathan Lucas designing a computer named Siafu with an entirely new concept that allows users with visual impairments find it all on their screen. Make use of materials with named Magneclay, the computer screen can be turned into a braille display, or even form an image morphing.
Magneclay an oil-based materials with a loose structure of the molecule, when energized by an electrical charge, this material can alter the shape-shifting into a new shape indefinitely as long as the electric charge is still exist. "Siafu" is derived from African languages which have meaning a blind ants, an allusion to the target audience is visually impaired PC. This computer is so versatile, there are several modes for the user to be able to do what is needed. On the computer keyboard is used nine-key braille with braille reading, or can be used as a book, and displays the words in braille.
"Siafu" can also create an image on a web page in three dimensions, making the user feel what's on their screen. Image conversion technology, along with the stunning nature of Magneclay, allowing images to be translated into a realistic three-dimensional display.
And also "Siafu" can synthesize the words on the screen and read aloud. And if the user chooses not to type, they have the option to speak into the microphone computer, where the voice recognition software to translate spoken words into words typed them. Siafu is one of the most advanced design ever intended for the visually impaired with a simple computation so that blind people can understand it better. And because Magneclay very flexible and can be reused indefinitely, virtually nothing that can not be displayed.
