Have anybody considered/tested others ways of displaying Braille?
E.g.
1. use lots of tiny heat emitter in place of dots
2. use heat/electrically deformable material(e.g. nitinol coil) to create the bump?
3. use tiny air valve to inflate little dots

Use Static Charge

And once you incorporate the annotated ideas, you can delete the annotations. Good plan! ;) |

lol don't worry, I won't! geeze chill! |

There are already Braille transcribers, which consist of an
array of pins driven by solenoids, in a little cluster. They can
display Braille characters. |
|
| |
However these display are pretty expensive, and is also pretty large. |
|
| |
There has got to be alternative ways to do this, that is either cheaper, or smaller/compact, or both |
|
| |
The basic braille transponder is pretty small and cheap - it's
basically the size of a die. But yes, interesting to consider
other options. |
|
| |
What if the Braille weren't exactly bumps or dimples but were a definite change in texture or somesuch? I'm thinking some kind of electrostatic or nitinol-like carpet that sticks straight out under charge but flattens smooth with none. |
|
| |
[RayfordSteele] kinda like a kindle for the blind? |
|
| |
Actually that would be pretty cool. |
|
| |
I don't know where I read it but someone somewhere
describes the realistic possibility that a blind
person could read the words off the pages of a book just
by detecting the differences in heat radiation hitting his
forehead given by the black ink. |
|
| |
Only if you put a headline under the grill and then pressed it
to your forehead. The words "bollocks" and "focus" spring to
mind. |
|
| |
I suppose there's always the possibility of selectively
blowing through little airholes, like on an air-hockey
table but much smaller in size, to inflate / deflate
bumps or dimples as you scan across. |
|
| |
But that sounds mechanically complicated. Better
would be a electromagnetic dimple system of some
type. |
|
| |
Was starting to post an anno, but spun a different idea. (link) |
|
| |
According to Wikipedia, two groups, Leuven University in Belgium, and NIST, are developing rotating-wheel Braille displays, which would be smaller and simpler, and (once in production) cheaper, than conventional displays. |
