1) A display screen to use as an interactive whiteboard (eg. TV, monitor or a projector).
2) A device to install the application (eg. PC, mobile device or a tablet)
3) A cable or mirroring equipment (HDMI, DVI, Mirrorcast, Apple TV etc) that connects the devices 1) and 2).

Please note that mirroring may cause slower writing speed.
