Wii + MacBook Pro + Dome

Experiments using the Nintendo Wii as a wireless 3D interface device.

Hardware: Wii remote, Mac Book Pro, 3m diameter dome, SXGA+ data projector.

Software: DarwiinRemote, DarwiinRemotePatch, qcwii and locally developed interactive and navigable movie software to generate realtime graphics for the dome.

With 3 axis accelerometers and a bevy of buttons (12) it is interesting to speculate how a Nintendo Wii might be used in other ways besides those associated with the Nintendo gaming console. The Wii is a (wireless) Bluetooth device and as such one can readily create applications that access the Bluetooth data and respond accordingly. Indeed at the time of writing this there are projects well underway that interface the Wii to Mac OS-X, Linux, and MSWindoze.

The exercise illustrated here was to evaluate the potential of the Wii as a low cost wireless 3D interface device that could be used for interaction within an immersive environment. The software being interfaced was all local so there was maximal flexibility to add direct Wii/Bluetooth functionality into the application code.

The result was a usable but inaccurate navigation device, at least as far as the accelerometers were concerned .... the buttons were fine but then that is similar to a Bluetooth keyboard. These tests were not performed using the IR sensor and that can undoubtedly be used to improve the accuracy when used in conjunction with the accelerometers.

Update

As expected the IR sensor makes a huge difference to the accuracy of the Wii as a pointing device. Unfortunately just using that only results in navigation in the plane perpendicular to the Wii axis, again not much more than a Bluetooth mouse. An interesting experiment would be to use the IR sensor as a form of stabilisation for the 3D mouse navigation, something I expect the Nintendo does.
