Patent Images
1. A tactile braille display comprising:
- a movable pin configured to be in a first position and a second position within a display substrate, the movable pin including a first end, a shaft, and a second end,the first end being configured to provide a raised dot of a braille character when the movable pin is in the second position,the shaft being configured to secure the movable pin within the display substrate and move in a helical path within the display substrate,the second end including a cam;
a write head configured to engage with the cam to position the movable pin in the first position and the second position, wherein the write head is configured to move in a direction that is perpendicular to the movement of the movable pin.
