This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures,…

This paper documents issues in converting the Figure Classification Test to the computer. The purpose of the test, which is almost entirely visual, is to determine the subject's ability to discover rules via the visual/spatial environment. The methodology of the paper-and-pencil Figure Classification Test is as follows: the subject views a series…
