Braille Computer Monitor
The braille computer monitor has rows and columns of rectangular cells. The cells include four rows and two columns of dots that can be felt for interpretation by the user. "The pins are driven by electromechanical impact drivers and are held in position by resilient elastomeric cords. The impact drivers are carried on a bi-directional printhead which travels beneath the movable pins. An erasing mechanism is provided to positively drive the pins downwardly to erase the characters produced by the printhead." The braille computer monitor is under the United States Patent 6700553.

Famous quotes containing the words braille, computer and/or monitor:
“she will not say how there
must be more to living

of the raucous bed or even
the slow braille touch of him
like a heavy god grown light....”
—Anne Sexton (1928–1974)
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“It is indeed typical that you Earth people refuse to believe in the superiority of any world but your own. Children looking into a magnifying glass, imagining the image you see is the image of your true size.”
—Franklin Coen. Joseph Newman. The Monitor (Douglas Spencer)
