They allow users to interact with the content on the screen using a stylus or their fingers, and can also be used to annotate, draw, and manipulate digital content. Electronic whiteboards are often used in educational settings, boardrooms, and other collaborative environments to enhance engagement and communication. They can also be used to save and share the content created during a session. **
