Emotional evaluation of TV-CM using the fractal dimension and the largest Lyapunov exponent

Researches of measuring and evaluating human emotions have evolved every day. While a variety of measurement methods exist the method of collecting the emotional evaluation data with the highest accuracy is using fMRI. But some serious problem has been left in this measurement method, for example the device being still expensive and the mental burden being given to the subjects while experimenting. In such a situation, about two years ago, we met the research method of the largest Lyapunov exponent researched by Dr. Mayumi Oyama at Kwansei-gakuin university.
