Implications for Emotion: Using Anatomically Based Facial Coding to Compare Emoji Faces Across Platforms

Emoji faces, which are ubiquitous in our everyday communication, are thought to resemble human faces and aid emotional communication. Yet, few studies examine whether emojis are perceived as a particular emotion and whether that perception changes based on rendering differences across electronic platforms. The current paper draws upon emotion theory to evaluate whether emoji faces depict anatomical differences that are proposed to differentiate human depictions of emotion (hereafter, “facial expressions”). We modified the existing Facial Action Coding System (FACS) (Ekman and Rosenberg, 1997) to apply to emoji faces. An equivalent “emoji FACS” rubric allowed us to evaluate two important questions: First, Anatomically, does the same emoji face “look” the same across platforms and versions? Second, Do emoji faces perceived as a particular emotion category resemble the proposed human facial expression for that emotion? To answer these questions, we compared the anatomically based codes for 31 emoji faces across three platforms and two version updates. We then compared those codes to the proposed human facial expression prototype for the emotion perceived within the emoji face. Overall, emoji faces across platforms and versions were not anatomically equivalent. Moreover, the majority of emoji faces did not conform to human facial expressions for an emotion, although the basic anatomical codes were shared among human and emoji faces. Some emotion categories were better predicted by the assortment of anatomical codes than others, with some individual differences among platforms. We discuss theories of emotion that help explain how emoji faces are perceived as an emotion, even when anatomical differences are not always consistent or specific to an emotion.

Detection of Human Facial Expression using CNN Model

Facial expression is the most effective and herbal non verbal emotional conversation method People can range indoors the way they display their expressions Even pics of the same character within the identical countenance can vary in brightness historical past and pose and these variations are emphasized if thinking about particular subjects because of versions in shape ethnicity amongst others Hence countenance recognition remains a challenging trouble in PC vision To advise a solution for expression reputation that uses a combination of Convolutional Neural Network and precise picture prepossessing steps It defined the modern-day solution that has green facial capabilities and deep gaining knowledge of with convolutional neural networks CNN's has achieved high-quality success within the classification of assorted face emotions like glad angry unhappy and impartial Hundreds of neuron smart and layer smart visualization techniques have been applied the usage of a CNN informed with a publicly to be had photo data set So it’s positioned that neural networks can capture the colors and textures of lesions unique to respective emotion upon analysis which resembles human desire making.

EMOTION EVALUATION FROM FACIAL EXPRESSION RECOGNITION USING AI TECHNIQUES: A Review

Facial expression is a primitive element for human interactions. To understand human behavior or mood, it is essential to analyze human facial expression from multidimensional sensitive and feeling image data. Various Artificial Intelligence based techniques are used for facial expression evaluation. In this paper an attempt has been done to Facial expression recognition & emotion evaluation. Previous and recent researches have been investigated to find out the related effective method
