Σύνοψη	Visual elicitation single case study is a qualitative design that embeds photo or image elicitation techniques within a bounded, in-depth investigation of a single case — a person, community, program, or event. Photographs, drawings, or participant-produced images are introduced into interviews to prompt richer, more vivid accounts than verbal questioning alone can generate, while the single case study frame provides the disciplined contextual analysis needed to understand the case as a whole.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
