Op-Glyph: a tool for exploring op art representation of height and vector field data

We report our experiences with application of the optical art techniques of Victor Vasarely and Bridget Riley to visualization of height field and vector field data. The bold use of color and simple form in Op Art engages the preattentive processing ability of the human visual system, facilitating a nearly instantaneous perception of image properties without the need for extended scrutiny of component parts. A software system called Op-Glyph was constructed to illustrate the Op Art method for data visualization, providing a user with extensive control over a visual representation's primitives, including shape, size, and color. Initial results suggest that this glyph-based approach to data visualization may be a viable alternative or complement to more complex representation schemes, particularly in situations where there are limited processing or graphical capabilities, such as with PDAs.
