Grids, matrices, and tables are commonly used to organize information. A number of design techniques and psychological principles address how viewers’ eyes can be guided through a visual work. Designers refer to such objectives as "creating visual flow." One common technique, “zebra-shading,” is intended to guide eyes through the grid by alternating shaded and unshaded rows or columns. However, the effects of these manipulations have largely not been explored experimentally. We will review the techniques designers use to guide the eyes of their audience, associated psychological foundations, and outline some research done on the graphic design of a specific type of grid: tables. Then, we will describe an experiment wherein participants conducted a visual search task in grids with different shading manipulations. The analysis showed data trending toward improved response time when the target followed the shading.
