Abstract
Emotionally pleasant experiences trigger repetition in humans whilst their emotional opposite lead to avoidance/refusal of activities. Human interest, a key factor in everyday human life, can be quite useful in the evaluation of participant engagement on activities and their optimization, so as to maximize interest and motivation. A glaring issue however comes from subtle demonstrators associated with human interest, which converge onto its complex assessment/quantization. Yet, there is an inherent correlation between human interest and its provoked emotional response which can be explored in tandem with emotion recognition for the development of an engagement metrics tool. Such a mechanism would be highly beneficial for the improvement of several activities involved with learning and security, by enabling precise control over participant enthusiasm. In this paper we present an interest mapping technique which provides the user with spatio-temporal information extracted from a participant crowd. The technique aims to extract emotional cues from participant facial data, assessing its spatial and temporal distributions over the course of scenarios such as therapy sessions and lectures. The goal is to demonstrate where and when activities must be improved in order to retain attention, maximize efficacy and assure emotional pleasantness in participants. For validation, this study makes use of data collected over a college lecture so as to provide readers with a real demonstration of the technique's advantages.
Highlights
Emotion is extremely influential to our behavior in any situation, holding a pivotal role in human life
In this work we present an interest mapping technique based on the recognition of archetypal emotions based on facial expression
In order to infer conclusions based on crowd emotion, and considering how participants are most often silent and still, deeming speech of body emotion recognition inadequate, facial emotion recognition (FER) was employed as the best alternative
Summary
Emotion is extremely influential to our behavior in any situation, holding a pivotal role in human life. [1] demonstrated how emotion acutely modifies our physiological responses to different situations. Though its study has been relatively intensive over the last century, with several models being presented such as the emotional wheel [3] or the Pleasure-Arousal-Dominance (PAD) [4], its aspects as a regulatory metric for therapeutic or rehabilitation procedures has seldom been given attention by the research community. This demonstrates a blatant disregard for the link between triggering/retardant emotionality and attention/interest. This notion is supported by several views in the field of psychology and behavioral studies, such as iJOE ‒ Vol 18, No 02, 2022
