Paper Abstract:	In this present study, the effects of spacing between items, view direction, and forward-rotated angle on errors in the perceived height of a rotated three-dimensional figure were investigated. Our results indicate that the spacing between items had a statistically significant effect on errors in perceived height, and that fewer errors in perceived height were made when judgments were based on a bottom-up view than based on a top-down view. Errors in perceived height were significantly smaller in response to a 15° forward-rotated angle compared with a 30 and 45° forward-rotated angle. These results have implications for graphics-based interface design, such as that used in interior design, driver navigation systems, and geological models.
