A new Nintendo Wii accessory may be worth investigation for the WiiCane project. The MotionPlus controller accessory adds additional sensing capabilities to the controller, complementing the standard 3 degrees-of-freedom accelerometer features with angular rate change sensing.
Nintendo unveiled the MotionPlus at last year's E3 and announced plans to begin shipments in 2009. See Nintendo's press release for more information.

Zach,
From the web: “Called Wii MotionPlus, the controller attaches to the Wiimote to provide what the company calls ‘more comprehensive tracking of a player's arm position and orientation.’ In other words, a true reading of where your arm is in space, allowing for 1:1 movement; and “more quickly and accurately reflecting motions in a 3-D space.”
Some straightforward questions:
* Off the self cost for the controller? Looks like it ad $15 to the cost.
* What is the weight?
* The angular rate changing sensing is interesting. Of course my naive question is, in terms of functionality, what would it add to the data for detecting/calculating our variables: cane arc width, cane amplitude, hand centeredness.
This sounds very promising.
this looks positive. Anything that we can do to improve the system's accuracy and detail about movements will probably be useful to us. Should we try to find out more about the supplementary information provided by Motion Plus, or continue developing methods for harvesting relevant position parameters using the existing data? Also, I see that the Motion Plus adapter plugs into the expansion port on the wiiMote. does that preclude the use of other accessories, or can they be daisy chained?
