Hello, there must be some unit based on 6 solenoids that are controlled by external logic. May be that those units are difficult to find, but i've seen them used as "display" in a telephone set for visually impaired people. For a VERY limited number of characters, you can try to build one by yourself, using 6 microrelays for each digit and some rigid wire to couple the moving part of the relay to the tactile "dot", in order to create the appropriate Braille patterns. That's a very complicate solution 
... Better if you find the commercial parts.
