The Smart Board is an interactive whiteboard system that includes a computer, projector, and software. It allows users to control the computer by touching the board like a touchscreen. Some key features include digital ink, infinite cloning, capturing and annotating parts of the screen. Using a Smart Board in teaching has advantages like encouraging student engagement, supporting visual and tactile learners, and allowing information to be presented interactively. However, they can be expensive and sometimes difficult to write on compared to a traditional whiteboard.
