The hardware devices were an interactive electronic whiteboard, all-in-one touchscreen desktop computers, a
material server, and the wireless access point. Interactive electronic whiteboard in the study was a 72-inch
touchscreen shown in Figure 2. Connected to a computer and a projector, the whiteboard projected the content of
the computer and allowed its users to perform such functions as move, turn, and click to edit and operate with
fingers or a touch pen. Not only can the whiteboard present multimedia materials, it can also store operational
processes for later access.
