Overview
As you saw in the previous chapter using the Wii remote, the controller is quite a versatile tool that contains a number of interesting sensing capabilities and is relatively easy to connect to a PC. This chapter describes how to create a multi-point interactive whiteboard surface using the camera built into the front of each controller.
This chapter will cover only the implementation details specific to creating an interactive whiteboard. It assumes that you have already successfully connected a Wii remote to a Bluetooth-compatible computer. If you are uncertain about how to do this, refer to Chapter 8 for instructions.
