“…Reading familiar words were faster and more accurate. Earlier designs which allowed for lateral deformation of the fingertip included the rotating wheel braille display [10,11].The rotating wheel design [10] used fewer actuators (3 actuators for 6 dot braille, 4 for 8 dot braille) in a compact volume having a drum with a small diameter. The pins would be set just before it entered into the reading area of the device which was under the users' primary reading finger.…”

Unlike sighted readers who read whole words at a glance, braille readers construct words sequentially processing them character by character as their tactual field of view is small. Using this aspect of braille reading, we conducted an experimental study to investigate whether nonsensical characters moving under the reading finger would be a hindrance in reading words .We used a prototype to display braille with a single actuator .There is a lateral presentation of text to the user using a 3D printed braille embossed disc which rotates under the reading finger of the blind person. Preliminary test results indicate that users can read words even as nonsensical letters brush past the reading finger. This feature has implications in the design of a cost effective braille display.
