Fabrizio Giudici, a World Wind Java early adopter, reports yet again a Wii remote related demo involving the NASA SDK. The project called Montenav demonstrated by Gianpaolo Melis at the JUG Genova uses the Nintendo hardware to control the WW globe using gestures.
In the above video the red and green dots are the two hands being tracked simultaneously. Gianpaolo Melis used IR leds attached to his hands to communicate his gestures to a fixed Wii remote.
For more details see Fabrizio Giudici web log.
Last January i reported another project involving Wiimotes and World Wind - the .net version. Recently, j_c_maglio, a WWJ forum member mentioned working on a related project.
