Emotional Analysis in Animated Films Using Big Data and IoT: An In-Depth Study of 'Krek'

This study explores the intersection of narrative structure, color variation, and audience emotional response in the classic animated film "Krek" from the Zagreb School of Animation. Utilizing a combination of Big Data and IoT technologies, we captured over 500 frames at one-second intervals using the Color Summarizer platform to extract key color properties such as hue, chroma, and lightness. This granular dataset enabled a detailed analysis of color dynamics throughout the film. Audience emotional responses were quantitatively assessed using manual annotation and plotted to generate emotional curves. Pearson correlation analysis was conducted using SPSS to examine the relationships between emotional intensity, specific emotional states (pleasure, sadness, and disappointment), and color attributes. The results revealed a strong correlation between audience disappointment and color attributes, particularly chroma, highlighting the film's effective use of color to evoke specific emotional responses. Our findings demonstrate the significant impact of color changes on emotional modulation in the film ‘Krek’ and underscore the unique narrative and visual techniques employed by the Zagreb School of Animation. This research contributes to a deeper understanding of how visual and narrative elements interact to shape audience emotions, offering valuable insights for the design of emotionally engaging animated films.
