Large Print System on a Graphic Computer Terminal for Visually Handicapped Programmers.

Abstract

For the person with normal vision, an interactive cathode ray tube terminal with graphic capability is a useful two-way window to the operation of a computer. For an individual with very limited vision, such a device is difficult if not impossible to use because of the small alphanumeric print size. A software-generated graphic print set has been developed for a Tektronix Model 4016-1 terminal. This point set operates as automatically as the alphanumeric print sets that are a part of the terminal. The print can be adjusted from some arbitrarily small size to 2 inches in height. With this capability, the terminal can be very useful to an individual with very poor vision. (Author)
