Hayes, Brian C., Kurokawa, Ko and Wierwille, Walter W. (1989): Age-Related Decrements in Automobile Instrument Panel Task Performance. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 159-163.

“This research was undertaken, in part, to determine the magnitudes of performance decrements associated with automotive instrument panel tasks as a function of driver age. Driver eye scanning and dwell time measures and task completion measures were collected while 24 drivers aged 18 to 72 performed a variety of instrument panel tasks as each drove an instrumented vehicle along preselected routes. The results indicated a monotonically increasing relationship between driver age and task completion time and the number of glances to the instrument panel. Mean glance dwell times, either to the roadway or the instrument, were not significantly different among the various age groups. The nature of these differences for the various task categories used in the present study was examined.”

Decker, Jennie J., Dye, Craig J., Kurokawa, Ko and Lloyd, Charles J. C. (1988): Effects of Display Failures and Symbol Rotation on Visual Search Using Dot-Matrix Symbols. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1386-1390.

“This study was conducted tin investigate the effects of display failures and rotation of dot-matrix symbols on visual search performance. The type of display failure (cell, horizontal line, vertical line), failure mode (ON, failures matched the symbols; OFF, failures matched the background), percentage of failures (0, 1, 2, 3, 4%), and rotation angle (0, 70, 105 degrees) were the variables examined. Results showed that displays which exhibit ON cell failures greater than 1% significantly affect search time performance. Cell failures degrade performance more than line failures. Search time and accuracy were best when symbols were oriented upright. The effects of display failures and rotation angle were found to be independent. Implications for display design and suggestions for quantifying the distortion due to rotation are discussed.”

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.”
