Wii Gesture Project - version 2

...one step further to having some gesture recognition!

Have a look at the video.

(Once again, if the video quality is too iffy for you, go here)

You will see that the application records the user's gestures in groups of 8. The movements, each direction represented by a number, are stored in an array (or 'list' as Lingo would have us call them!). At the end of every group of 8, the array is condensed into a single string. This forms the basis of a Levenshtein Distance comparison string - I'll explain this in another post, but it's a core part of the application nevertheless!)

For example, the application may output:
movementList = [1, 2, 1, 2, 3, 5, 1, 5]

...therefore...

movementListLev = "12123515"

We take each number...
1=up, 2=up-right, 3=right, 4=down-right, 5=down, 6=down-left, 7=left & 8=up-left

So we know from 'movementListLev' that the user has moved the Wii Remote up, up-right, up, up-right, right, down, up & down.

There is a problem with this method of data collection and that is that a complete gesture must fall perfectly within each group of 8 movements. The next stage in the development will involve creating the array/list so that newest movement numbers push out the oldest numbers, that way the 8 most recent movements are ALWAYS shown...
