Braille Reading paper from Michael

These guys used pen attached to the dominant finger of the blind person a little bit above of the blind participant's finger tip and by this way they could capture the finger trace. And one thing was interesting that they gave freedom to the participants to read or scan on their own way and this is a good lesson which we might use to get a natural finger movements of the participants. So I still believe using eye folded persons instead of real blind subjects would make difference in analyzing finger tracing behavior and letting the participants use much freedom for their finger movement would bring much real observation.
