概要	A Remote Focus Group is a synchronous, moderated group discussion conducted via video or audio conferencing rather than in a shared physical space. Participants — typically 5 to 10 people — join from separate locations and discuss a topic guided by a trained moderator. The method preserves the core strengths of in-person focus groups (group interaction, idea building, spontaneous reactions) while eliminating geographic barriers and reducing recruitment costs. It has become a mainstream qualitative data collection approach, especially following the widespread adoption of video conferencing platforms.	A remote semi-structured interview is a qualitative data collection method in which a researcher conducts a guided, flexible conversation with a participant over a distance-bridging medium — telephone, video conferencing, or voice-over-IP — using a prepared topic guide with open-ended questions while allowing natural conversational elaboration. It combines the structure and comparability of a protocol-driven approach with the depth and flexibility characteristic of qualitative inquiry, delivered without physical co-presence.
