It would mean there would be much more interactive options for games running on the phone though. Like pinball, or driving games. A golf game where you swing the phone maybe?

Re: accelerometer in neo?
In addition to an accelerometer, the wii remote has a 1 megapixel camera for sensing the position of two infrared leds at each end of the sensor bar which is placed above or below your TV. The accelerometer measures motion and orientation, whereas the camera is used for direct pointing / cursor movement. (Any game/app that tells you to point the wiimote at the screen) Without a camera on the neo, you will not be able to emulate that part of the wiimote functionality. It might be possible to emulate the nunchuck in some way(which doesn't use a camera, but has a thumbstick and two buttons in addition to it's accelerometer), but it definitely couldn't fully emulate the remote.

RE: accelerometer in neo?
Hi, Wouldn't expansion via existing usb or BT be preferable? If a few types of hardware that's accessable via these ports has been developed with some sort of driver and application then further development will have a foundation to work off of and the usefullness will be clear for incorporation into later versions of the phone. E.g, rather then embed the accelerometer in this version of the phone, use the ezusb chip to develop the application.

To be boringly pedantic. An inertial guidance system is not possible with simply a 3 axis accelerometer. You need at least three angular rate sensors to pick up the roll, pitch, and yaw. (which way it points) In practice, semiconductor inertial guidance at the moment isn't suitable for more than a few seconds at a time. The drift rate is _horrible_ - a kilometer position uncertainty after 3 minutes, 400Km in an hour. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
