摘要： A device comprising rotating cylindrical shafts to create a virtual sensation of Braille text by integrating a microprocessor with microdrive actuators. The microdrive's shafts are flush or level with the device's display surface thereby emulating the standard diameter and feel of a Braille dot or Braille space. This sensation of a rotating dot is the result of the top face of the shafts positioned flush with the device's display surface. Actuators that alternate between rotating shafts and shafts at rest produce Braille cell dots and spaces, respectively.

摘要： The present invention is directed to a haptic system of rotating cylindrical shafts topped with caps to create a virtual sensation of Braille text by integrating a microprocessor with microdrive motors. The micro drive's shafts are crowned with plastic cylindrical caps, the top face of which are precisely flush or level with the device's display surface thereby emulating the standard diameter and feel of a Braille dot or Braille space in two dimensions. It is the rotation of the drive's shaft that spins the caps and simulates the sensation of a Braille dot that is felt with the fingertips. This sensation of a two dimensional rotating dot is the result of the top face of the capped shafts positioned flush with the device's display surface. Motors that alternate between rotating shafts and shafts at rest produce Braille cell dots and spaces, respectively.
