Requirements to use an iPad as an IWB. You need:- iPad- laptop or desktop computer (Apple is best, of course, but Windows computers can work as well since identified software is cross-platform)
- WiFi network connection (configured with ports open to allow sharing/communication between the iPad and computer - this can be an ad-hoc network or a 'normal' wifi hotspot / network)- LCD projector with screen or large format TV to serve as the external display
- remote control app (ex. Air Display, Splashtop, Team Viewer)- Software applications which support both remote control and remote mirroring of a computer screen, along with screen annotation / recording (IWB-like software)
