- In designing an automobile seat, it is important to minimize the fatigue experienced by the driver resulting from long-term sitting. We have utilized the following measurement techniques to quantify driver fatigue during actual road-test conditions.
-
(1)
subjective evaluations of fatigue based on multi-dimensional scaling;
-
(2)
measurement of body movement by an electromagnetic field transducer; and
-
(3)
electromyographic recordings (EMG) of muscle activity.
These methods were used during four hour driving tests involving five subjects in each of four seats which differed in design. For each subject, a weighted fatigue index based upon responses to a questionnaire was calculated. Body movement was analyzed by using a position transducer attached near the iliac crest. The EMG median freqency and amplitude were analyzed for eight muscles of the back. By recording these measurements simultaneously, we have provided a means of comparing subjective indices of driving fatigue with objective physiological parameters. -
