Have you tried?
The new touchscreen monitor in HSB1345, just swipe your finger across and advance your PowerPoint slides. You can annotate with either the pen (which I only know where it is hidden) or your finger. HSB classrooms are due for refreshing and 1345 is a preview.
You also can use the new feature AirMedia which allows you to have your student(s) login and then you can project their screen onto the “big” screen. The refreshed rooms will also have a “bridge” which will enable use of the in room cameras for Skyping or WebConferencing.
