The Isolator

Invented by science fiction pioneer Hugi Gernsbeck, the “Isolator” was designed to help focus the mind when reading or writing, by rendering the wearer deaf, piping them full of oxygen, not only by eliminating all outside noise, but also by allowing just one line of text to be seen at a time through a horizontal slit.
