          We devised and tested two new visual guides to help users comprehend distorted sketched information in magnification lenses. Distortion techniques, such as fisheye lenses, have the advantage of magnifying information without occluding the surrounding content. However distorted information in the transition region requires extra mental workload to understand: this can lead to frustration and rejection of magnification lenses. Our evaluation shows any visual guide is better than none and identifies strengths and weaknesses of the new guides. We tested for the four visual properties important for understanding distorted information: scale, alignment, distance and direction. Surprisingly grids are not as effective in many contexts as our new lenses.

            Graphical perception and graphical methods for analyzing scientific data.

            Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Recent investigations have uncovered basic principles of human graphical perception that have important implications for the display of data. The computer graphics revolution has stimulated the invention of many graphical methods for analyzing and presenting scientific data, such as box plots, two-tiered error bars, scatterplot smoothing, dot charts, and graphing on a log base 2 scale.
