more wii plots
Friday, October 24th, 2008So after all today’s hard work, still some time for a bit wiimote fiddling 
I extended my test app to show the raw accelerometer data.
A few words about what is which graph and the color coding:
The left graph shows the same as 2 days ago, except, I switched the colors to remember the meaning more easily.
Red is for Roll =) and blue is the pitch. These data are calculated by the wiiuse library.The right graph shows the raw accelerometer data. It is simply showing the x (red), y (green) and z (blue) component of the acceleration vector.
The experiment here shows 2 rolls to the left (and return), followed by 2 translations to the left. One could argue that a translation to the left, from the accelerometer’s viewpoint, is just the same as a roll, since both are changing the gravitation vector temporarily in a similar way. I’d say there still seems to be a difference.. 
Paul, I’m open for discussion
