MEASURING INSTRUMENT OF CONCENTRATION DEGREE

摘要

PROBLEM TO BE SOLVED: To provide a measuring instrument of a concentration degree capable of stably and certainly measuring the concentration degree of a measuring target person to judge the same so as to be matched with the state at the time of measurement. SOLUTION: The measuring instrument of the concentration degree is equipped with: a pulse wave sensor 4 for measuring the pulse wave of the measuring target person; an acceleration sensor 22 for measuring the movement of the measuring target person; an arithmetic means 23 for calculating not only automatic nerve activity from the measuring result of the pulse wave sensor 4 but also motion activity from the measuring result of the acceleration sensor 22 to calculate the degree of concentration from the automatic nerve activity and the motion activity; and a recording means 24 for recording the degree of concentration of the measuring target person calculated by the arithmetic means 23.
