Estimation of mode of viewing TV and preference of TV contents by autonomic nervous system index

Abstract

In this research, mode of viewing, preference, and excitement-calm to TV contents were estimated from the hemodynamics parameter to create the estimation model. As physiology indices, the cardiovascular system was assessed by mean blood pressure (MP), heart rate (HR), stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR). Comfortable, arousal, vigor, preference and concentration to TV contents were assessed by visual analog scale (VAS) for mental indices. Psychological excitement-calm to TV was assessed by up and down arrow key of a keyboard in real time. Based on the above indices, the estimation model was created by using the neural network. As a conclusion, the distinction rate of the preference and the mode of viewing were each obtained to 83.3% and 75.0% at the maximum. The average error of the excitement-calm was obtained to 17%0.
