1) Does the head tracking work with any specific images or can it work with a variety?


2)Is a laserpointer considered an infared LED?


3)If it is considered that, would it even be safe to point directly at a computer screen?(can't those things casue damage to it?)



4)In the head tracking, how do the targets appear on screen?  Is the computer connected?  How would it be?


Thank You?........Yea

1) Pretty much any image, there are posts on how to change it

2) No

3) Perfectly safe, it's just light.

4) In Johhny's vid his TV is connected to the external display port of his laptop, most people will just use their normal screen.

1 you can look at the load function and then look at msdn and see that there is a plethora of image formats to choose from
the function is TextureLoader.FromFile
the msdn article referencing it is
http://msdn2.microsoft.com/en-us/library/ms130474(VS.80).aspx
and the supported format is
Quote
This method supports the following file formats: .bmp, .dds, .jpg, .png, and .gif.

2 Laser is not the same as LED, however there are IR Lasers, like in some mice. the thing is, it is such a fine point on the board / surface your using as a whiteboard that the wiimote would have to be close to pick it up

3 any laser device is not safe to point into your head holes. (except the nose, ears and mouth but i take no responsibility). Lasers are concentrated light sources and can do serious damage to your ability to see your kids and grandkids.

4 how do they appear on screen? like how do they select the target image or how does it show up on JCL's tv? there are adapters to convert signals from computers to tvs but part of having the adapter is having the hardware to adapt it. you need to have a tv with a video input like a DVI or VGA or you need to have a video card that can output to S-Video or YPbPr or RCA. if you have to ask if it can do it, chances are that your card cannot, but, if you have a new enough tv, you should be able to output to a tv source. check your video card specs.

if you want to know about the target image, just crack the code open and look for stad_2.png and replace it with the image you want, and also put that image in the same path as the executable after you build it. this method of course requires you to have a development environment and if you do not, i suggest getting Visual C# Express because it is free and you can do lots of stuff with it.


Details, details. Things to do. Things to get done. Don't bother me with details, just tell me when they're done.
