An audience response system (ARS) is a technology used to gather real-time feedback from participants during presentations, lectures, or events. It typically involves handheld devices or mobile apps that allow audience members to answer questions, vote, or provide input anonymously. This instant feedback helps presenters gauge understanding and engagement. ARS can enhance learning experiences in educational settings, such as classrooms or workshops, by promoting interaction and participation. It is also used in corporate environments for meetings and training sessions. Popular examples of ARS include clickers and polling software, which facilitate dynamic communication between speakers and their audiences.
