General Discussion / Re: Flash Frame Rate VS Wiimote Scanning Frequency???
« on: September 27, 2010, 11:51:23 AM »
Hi Dexter,

The rate of output from the Wiimote is definitely much lower than 400Hz.

For your case, you may want to poll the the data from the Wiimote.

Hello Boon Jin,

Do you know what is the exact frequency of Wiimote?
Is it above 60 Hz?
Thanks.

General Discussion / Flash Frame Rate VS Wiimote Scanning Frequency???
« on: September 21, 2010, 04:09:42 AM »
Hi All,

I am doing a project with Action Script in Flash, to control the movement of a Flash character.
On the timeline, there is only a single frame, so what is the frequency of the movement of the character?
As I understand, the scanning frequency of Wiimote is 400Hz, and I used 24 frame/s in Flash.
My question is, is the frequency of character movement the same as the 24frame/s or depends on the coding in Action Script?
And if the frequency of the character IS the same as the 24 frames/s I set, is it possible that the movement becomes smoother when I set the frequency to 100 f/s?
If it is not relevant to the Flash frame rate, can I set it to 1 f/s and still get smooth movement?

Do I need a timer to get the data from Wiimote from time to time, eg, 1/X second?

Wiimote Finger Tracking / Re: How to differentiate tacking points?
« on: September 20, 2010, 06:47:11 AM »
Hi Dexter,

For your case, you may want to use the expected related position of the IR points to determine which is the left/right/head.

You may need to continuously track the positions of these 3 points so that when one of the points disappears, you are able to determine which are the existing points.

As the Wiimote is able to track IR blobs continuously as long as the IR point does not disappear, it may be useful for you as you do not need to track manually to determine the points.

Hello Boon Jin,

Thank you very much for your reply.
We thought about using the relative position of the 3 points as the tracking reference but the problem occurs when the points' relative position changes. For example, if at the beginning point 1 and point 2 are nearer to each other and point 3 is far from them, and later point 3 becomes nearer to point 1 and point 2 becomes farther from point 1, the programme will not be able to track the points correctly.

Wiimote Finger Tracking / How to differentiate tacking points?
« on: September 16, 2010, 11:23:07 AM »
I am working on a project using wiimote finger tracking to control a virtual shadow puppet programmed in Flash (ActionScript 3). The puppet is design to have 3 points on 2 hands and head, respectively. I want to fix each point at its position, for example, point1 is on head, point2 is on the left hand and point 3 is on the right hand. Because when performing, there will be fast movements, I'm worrying the three points may not be continuously detected, result in the change of the positions of the three points, for example, point1 becomes the left hand, point2 becomes the head, etc..

Is there any way to fix them permanently, so that even thought when one of the points, for example point2, is undetected at a short period of time, point1 and point3 are still fixed on head and the right hand, and when point2 is back, it still can be assigned to the left hand?

Thanks very much!
