Recognition of the need to move from research "on" children to research "with" children has prompted significant theoretical and methodological debate as to how young children can be positioned as active participants in the research process. Visual research methods such as drawing, photography, and videography have received substantive attention in child-centred research paradigms. However, despite their increasing ubiquity in young children's lifeworlds, technology or media-based visual materials have received little interest. This article reports on a study which used emoji as a visual research method for eliciting young children's (aged three to five years) understandings and experiences of well-being. Findings elucidate the capacity of emoji as a visual research method for eliciting children's voices, and considerations for its use in child research.
