Validity and reliability are two foundational concepts in research quality. Reliability refers to the consistency and reproducibility of measurements: do repeated applications of an instrument yield the same results? Validity refers to the truthfulness of inferences: does an instrument measure what it claims to measure
Viewshed analysis examines what is visible from specific locations or within a defined area using digital elevation models (DEMs) and geographic information systems (GIS). Pioneered by David Wheatley in the 1990s, the method reveals how landscape features (hilltops, valleys, water sources) controlled visibility and mov
Visual analysis is a qualitative research approach that systematically examines visual materials — such as photographs, films, artworks, advertisements, and diagrams — to understand how meaning is produced, communicated, and interpreted. Drawing on traditions from art history, semiotics, and social science, it treats v

Visual elicitation content analysis combines the photograph or image-based interview technique known as photo elicitation with the systematic coding procedures of content analysis. Participants are shown selected visual stimuli — photographs, drawings, video stills, or researcher-produced images — and invited to respon
Visual elicitation conversation analysis (VECA) is a qualitative hybrid method that uses photographs, drawings, maps, or other visual stimuli to prompt and structure participant talk, and then subjects the resulting interaction to systematic conversation analysis (CA). The approach leverages the evocative power of imag
Visual Elicitation Critical Discourse Analysis (VECDA) is a qualitative methodology that uses photographs, drawings, or other visual materials as prompts to elicit participant talk, then subjects both the visual artifacts and the resulting discourse to critical discourse analysis (CDA). The approach uncovers how power,
Visual elicitation digital ethnography is a qualitative research design that embeds visual elicitation techniques — using photographs, videos, or digital images as interview stimuli — within digital ethnographic fieldwork conducted in online or digitally mediated environments. Participants produce or select visual mate
Visual Elicitation Discourse Analysis (VEDA) is a qualitative method that uses photographs or other images as interview stimuli to generate participant talk, which is then subjected to systematic discourse analysis. By anchoring conversation in concrete visual materials, VEDA accesses meanings, ideologies, and subject
Visual elicitation document analysis is a qualitative method that uses visual materials — photographs, drawings, institutional images, maps, or archival visuals — embedded within or alongside documents to prompt deeper participant reflection and to enrich the interpretive reading of those documents. By treating visuals
Visual elicitation ethnography is a qualitative research design that integrates sustained ethnographic fieldwork with the systematic use of visual stimuli — photographs, video clips, drawings, or participant-produced images — to prompt deeper, more reflexive accounts from community members. By combining prolonged immer
Visual Elicitation Grounded Theory (VE-GT) is a qualitative design that augments classical grounded theory with visual elicitation techniques — photographs, drawings, video stills, or participant-produced images — as the primary stimulus for data collection. Instead of relying solely on verbal prompts, the researcher u
Visual elicitation hermeneutic phenomenology is a qualitative design that combines the image-based interview technique of visual elicitation with the interpretive, context-sensitive tradition of hermeneutic phenomenology. Participants produce or select photographs, drawings, or other images related to a lived experienc
Visual elicitation institutional ethnography (IE) integrates photo or image elicitation techniques into Dorothy Smith's institutional ethnography framework. Participants produce or select photographs and other visual materials that represent their everyday experience within an institution; these images then anchor in-d
Visual Elicitation Interpretive Phenomenological Analysis (VE-IPA) combines the idiographic, sense-making framework of Interpretive Phenomenological Analysis with visual elicitation techniques — photographs, participant-produced drawings, or other images — to deepen access to lived experience. Visuals serve as concrete
Visual elicitation life history research is a qualitative method that combines the biographical depth of life history interviewing with the evocative power of photographs, personal objects, or other visual materials. Participants select or bring images that are meaningful to their life story; these visuals then serve a
Visual Elicitation Metaphor Analysis (VEMA) is a qualitative technique in which participants select or create images that represent their thoughts, feelings, or experiences about a topic, and then articulate the metaphors embedded in those images during a guided interview. Originally formalised as the Zaltman Metaphor
Visual elicitation multiple case study is a qualitative design that embeds photo or image elicitation techniques within a multiple case study framework.
