A braille printing device includes a device body; a linear actuator with an actuator body and an actuator hammer; a liquid ejection unit, including a liquid container a resin piston, and a dispensing tube; a slidable connector with a groove; a vertical stop; a trigger switch; a slide stop member; a slide holder plate including a slide holder back portion, a slide stop member, and first and second sliding rails; and a control unit, such that the braille printing device deposits spherical domes of printing fluid on a printing substrate to form a braille text.

A sign manufacturing system includes a printing base, a printing panel with a top layer, pressure sensitive adhesive and a transparent bottom layer, a bridge component, a sliding assembly, including an assembly body, a cutting laser, a liquid ejection unit, a curing laser, and a control unit, such that the cutting laser cuts out characters in the top layer without affecting the bottom layer, and such that the liquid ejection unit deposits spherical domes of printing fluid on exposed surface of the transparent bottom layer to form a braille text.

A structured description is generated for a digital image of a scene. The structured description may include a first feature and a second feature of the scene. The structured description may also include a first detail of the first feature and a second detail of the second feature. A portable braille sequence printer may generate braille text of the first and second features using the structured description. The portable braille sequence printer may further generate additional braille text regarding the first detail in response to a prompt from the user regarding the first feature.

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.
