Patent ID: 7306463

Claim:
A device to tactually display language to a user comprising: A device surface having a first plane in which is mounted in module mountings a plurality of independently controllable modules, each of said modules further comprising: a module surface having a second plane; a rotatable shaft connected to said module surface extending outwards perpendicular to said module surface and rigidly attached to a control system below said module surface for rotating said shaft in a controlled manner wherein said shaft is rotatable through at least 180 degrees; a tactually perceptible indicium rigidly connected to said shaft above said module surface wherein each said indicium: exhibits a first degree of rotation; and points in a first direction depending on said first degree of rotation; wherein said first direction pointed is representative of a first symbol when two or more of said independently controllable modules are operated together; and wherein each of said independently controllable modules is independently controllable as to rotation of said modules' indicium, so as to present a plurality of indicia to represent one or more character symbols; wherein each said module mounting in said device surface is dimensioned so as to allow said second plane to be flush with said first plane; and when grouped into 2 columns by 3 rows to represent a Braille character, 4 or more of said indicia are identical in shape.
