wait what? I'm not going to get on the case of an opinion, but soemthing strikes me as odd.

They are isolating the Z axis? why? First the Z axis as 2 different potential inputs. The accelerometer. Which would give the same response as the other 2 axis. The other being the IR. Which no offense is far more accurate because it can judge real distance do to have 2 reference locations as is faster in response.

Something tells me there is something is fishy. After visiting there site(if no one linked it http://www.cohortstudios.com/) can some one tell me what's wrong? simply put they don't have Wii titles. They have Sony titles. Which can tell you something really simple. The likely don't have an SDK which means they are probably using some crappy games as a template. This sounds like Sony PR pressure or Brownie points to me.

I would like to hear these kinds of opinion come from a developer who has a more nuetral track record. I don't notice a lot of Wii third party developers commenting on PS3 or XBox?

Wrong.  You can only use 2 reference points to judge distance if you know what angles those 2 points are at in relation to you.  Since the Wiimote can't tell what angle it is in relation to the sensor bar, it's basically impossible to tell how far away it is from the sensor bar.

EDIT:  Assume that the following is what the Wiimote is seeing:

o                                                                                                                                                          o

Assume that the two o's are the infrared emitters from the sensor bar.  You know that the sensor bar is 12 inches long (just hypothetical).  Can you tell me how far away from the sensor bar you are, and at what angle you are looking at the sensor bar from?  You can't.

It's a simple problem, so it's not surprising that Nintendo already thought of that with a simple solution.

That's a pic showing one end of the sensor bar, with the cover removed. The outermost LEDs are angled outwards to give the impression of increasing and decreasing distance between the outer LEDS and the middle three, as the Wiimote moves from side-to-side. Using the distance between either end of the sensor bar, and the size of the light sources (much like the orb on the Move controller), there's enough information to work out at what angle the Wiimote is.

There are some patents viewable in a post I made here which explain things a bit better.

I assume this was designed mostly to manage several cursors when there's a huddle of people around the TV.

Thanks for the information.  I take back what I said.
