Bring touch capability to your classroom’s flat-panel display by adding the SMART Board® interactive display overlay. The interactive overlay fits on select soft- and hard-screen flat-panel displays, enabling you to create an interactive learning center. Using the touch-sensitive protective glass overlay, you can access and control your computer applications, write in digital ink and then save your work into a single application. The overlay`s whiteboarding capabilities mean your digital course materials can be built upon and re-used.
