From DSC:

This is where publishers need to go — at least as part of their delivery of educational content. Bring up a textbook, maneuver to chapter ___, and drag the video from the left side of the screen to the right side. Or drag an entire chapter to the right side of the screen to have that chapter unfold before your eyes — and then select the item you want to focus on. Drag your fingers to enlarge the graphics/graph/photo/table/etc.; when you are done discussing that item, shrink it back down, gesture it to the side, and go to the next item. Have the board take pictures accordingly and send those pictures to multiple sources.

One part of the board could provide downloadable, discipline-specific templates

From Daniel Christian: The future chalkboard is connected to various other systems and devices -- wirelessly and via wired connections.
