Clickers are handheld devices used primarily in classrooms and large group settings to facilitate audience response. They allow participants to answer questions or polls in real-time, providing instant feedback to the presenter. This technology enhances engagement and interaction, making it easier for educators to gauge understanding and adjust their teaching accordingly. Typically, each clicker is assigned to an individual, enabling anonymous responses. The data collected can be displayed immediately, helping to visualize trends and opinions. Clickers are often used in conjunction with PowerPoint presentations and are popular in higher education and corporate training environments.
