Braille Kinematics and Neurodynamics
When blind persons read braille, a system of raised dots for tactile reading and writing, how is the information processed? How do a few indentations on the fingerpads translate to linguistic information, and how does the text, in turn, influence the motions of the hands reading it? Our work on braille addresses these processes on several levels.
Neuroimaging techniques such as EEG/MEG and fMRI offer the potential to trace the propagation of Braille information through the brain as it transforms from a dot pattern to meaningful alphabetic information, and comparing this to the analogous processing stream of printed letters in sighted people.
