Kurokawa, Ko, Decker, Jennie J., Kelly, Patti L. and Synder, Harry L. (1988): The Effects of Image Rotation on Dot-Matrix Characters. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1391-1394.

“This study investigated how rotation of dot-matrix characters influenced human performance, measured by the response time in a random search task. Factors that influence the extent of dot-matrix pattern distortion were identified, and their effects were investigated. Significant effects were found in angle of rotation (p=0.0046; 0 to 180 degrees in a 5-degree increment), target character's distance from the center of rotation (p<0.0001), and target characters (p<0.0001). Issues pertinent in predicting the effect of dot-matrix pattern distortion on performance are discussed.”
