EmojiGrid

A two-dimensional self-report tool, developed by Toet et al. (2018), in which participants rate the emotional content of a stimulus by clicking on a point in a grid whose axes are valence (horizontal) and arousal (vertical). Rows and columns of emoji faces are arranged around the grid to help participants anchor their rating on recognisable facial expressions, reducing reliance on written labels and language skills. EmojiGrid is useful in accessibility and cross-cultural research because it does not require verbal emotion vocabulary, and is widely used to evaluate affective captions, expressive media, and food-emotion associations.
