Abstract
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.
Claims9
A device for generating braille characters comprising a display surface having a plurality of braille characters, wherein each of the plurality of braille characters includes a two-column by three-row configuration of braille dots, wherein each dot of the two-column by three-row configuration is provided by one or more microdrive actuators connected to a shaft, wherein the one or more microdrive actuators are capable of spinning the shaft, and wherein an end of the spinning shaft provides a tactile dot on the display surface of the device.
