概要	Digital visual analysis is a qualitative approach for systematically examining visual materials that originate in, circulate through, or are consumed within digital environments — including social media images, video content, screenshots, memes, infographics, and online multimodal texts. Drawing on visual methodologies and digital research methods, it attends not only to what images depict but also to how they are produced, shared, and interpreted within specific digital platforms and social contexts.	Semiotic analysis is a qualitative method for interpreting how signs — words, images, sounds, gestures, and objects — produce and communicate meaning within a cultural context. Drawing on the structural linguistics of Ferdinand de Saussure and the triadic sign theory of Charles Sanders Peirce, and popularised as a research tool by Roland Barthes, semiotics moves beyond surface denotation to expose the connotative and ideological meanings embedded in texts and visual culture.
