The dependence of finger tip touch-pressure upon the condition of Braille reading

The finger motions and quickness of braille reading were investigated by way of recording the finger tip pressure on the braille and its time process. Subjects were separated into two groups. One group consisted of 5 experienced blinds and the other group consisted of 5 blinds who were beginners in braille reading. The comparison of obtained results from two groups gave some evidence for the following conclusion. The finger tip pressure was considerably increased for careful or difficult reading.
