Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context.

Peters, Robert D., Kloeppel, Esther, Alicandri, Elizabeth, Fox, Jean E., Thomas, Maria L., Thorne, David R., Sing, Helen C. and Balwinski, Sharon M. (1995): Effects of Partial and Total Sleep Deprivation on Driving Performance. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 935.

Official statistics from the Fatal Accident Reporting System indicate a trend toward an increase in fatigue-related accidents over the past five years. In addition, it is widely believed by researchers that the official statistics grossly underestimate the role of fatigue in accidents. This collaborative study was conducted to precisely define performance decrements that drivers experience under varying levels of partial and total sleep deprivation. A 4 (rested, partial, 36-hour, and 60-hour sleep deprivation) by 2 (gender) mixed factors design with repeated measures of driving performance in a high-fidelity driving simulator was used to define these performance decrements. Analyses revealed several critical driving performance measures that were significantly affected by sleep deprivation. Sleep deprivation effects were observed for speed, lateral placement variance, steering variance, lane excursions, and number of crashes, with dramatic deterioration of performance accompanying increasing levels of sleep deprivation. Regression analyses were conducted on the driving performance data to determine behavioral predictors of crashes. Lateral placement variance accounted for 86% of the variance in the number of crashes, demonstrating important safety implications and issues related to the development of both roadway and in-vehicle countermeasures. Development of countermeasures to detect drowsiness can help prevent crashes and enhance the safety of all road users. Future analyses of the data will include the application of neural nets to predict fatigue-related crashes.
