REAL TIME PATTERN EVALUATOR FOR CHANGE IN PSYCHOLOGICAL CONDITION

PURPOSE:To arouse a caution of a worker by displaying a change in psychological condition evaluated by a psychological condition change value judging/evaluating means to extract the change in psychological condition in real. CONSTITUTION:This apparatus is provided with an inspection/correction means 24 which inspects a specified wave by a first detection means 23 to correct errors of detection, a first processing means 44 which determines an interval of the specified wave, the size of a breathing frequency component in variation of the interval and a T wave height of an electro-cardiographic waveform, a second processing means 45 which determines an evaluation value at the evaluation time as given at each fixed interval for three index values determined to be a psychological condition evaluation value and a third processing means 46 which detects a change in the evaluation value at the evaluation time by the value before the evaluation time to be a psychological condition change value. Thus, a change in the psychological condition is evaluated by a psychological condition change value judging/evaluating means 34 which judges whether change and detection occurs based on a physiological mechanism using two change values to achieve a pattern evaluation of the change in the psychological condition in real time and the results are shown on a display means 35.
