Sažetak:
Many attempts have been made to evaluate mental workload using heart rate variability, but mostly with different kind of linear analysis, which are not enough sensitive to many influencing factors in the interaction of subject with task. In addition, claims that the normal heart rate variability reflects deterministic chaos now have been supported by many researches, including our previous studies as well. In this paper, an attempt was made to evaluate mental workload using chaotic analysis of ECG signals. The experimental section of the paper focuses on the estimation of non-linear measures of heartbeat dynamics (attractor plots, correlation dimensions, Lypunov exponent) in different resting and mental work situations. The results indicate that some of non-linear measures are sensitive to the amount of mental workload and could be very useful as a dependent variables in experiments dealing with assessment of cognitive activity in general.
