Patent Primary Examiner
A refreshable Braille display that connects to computers and serves as a computer monitor for sight impaired people. Integrated within the display are mechanical pins that are activated by either stationary or mobile actuators, such as coils or solenoids. These pins either move rotationally or vertically when activated by the actuators. Spacing of these pins is tight enough to display graphics. Additionally, the pins are arranged such that various heights of the pins enable 3D graphics.
