An interesting idea. Let me say that I think it would be possible, but it would not be easy.
The IR camera on the wiimote is capable of tracking 4 points (IR sources). These are communicated as XY coordinates via bluetooth. One of the biggest issues (this comes up in some Wii games) is that it cannot tell where the IR source is in 3D space. One solution would be to use two or three remotes together. With a careful and consistent setup, you could use the XY coordinates from different IR cameras to determine a precise point in 3D space of an individual IR source.
The other issue is that of the IR source itself. The wii remote has no way to distinguish between different points of IR light. That is to say, if a foot had several sources of IR light, the remotes would not be able to tell which was which. In my experience, the remote will consider the first dot it finds to be dot 1, and the next to be dot 2, and so on. So you can control this (by turning on IR sources in sequence) between several remotes only if all dots can be seen by all cameras at all times.
Does this answer your questions?
Hi Dave,
If I assume that the there will be one led for each foot finger then I can compare their X positions and see which one come after another in order to determine which finger it is.
Since on my application we would instruct the user to use the application correctly (to handle those situations).
For example, the camera would interpret the X positions of the fingers like this: point1X = 10, point2X = 12, point3X = 14, point4X = 16, point5X = 18, so I can suppose that point1X is the first finger from the left foot.
My problem is with the Z distance, since it would influence in my application.
Some people said that I could use the blob size but how can I obtain it? another thing is: I could not understand how it would be when putting 2 or 3 controllers together, I didn't get it.
Thank you very much and answering to your question, yes you did, but the more you dig, the more we find :-)
