Microphone Port
A built-in microphone port means that with Nintendo DS, you only need to tell your games what to do.
Developers could create games which identify everything from voice commands to hand-clapping. Imagine moving your characters simply by telling them which way to go! Communication-based games could use the microphone and you can chat with others over a local network, or even the Internet in the future.
The Nintendo DS microphone gives you even more ways to interact with your favorite games.
System
With Nintendo DS, dual screens and touch-screen technology allow you to interact with games like never before. Wireless communication allows you to experience real-time multiplayer gameplay, while built-in PictoChat software gives you the power to draw, write and send messages wirelessly. Nintendo DS revolutionizes the way games are played.
