hello :)

after i saw your video on youtube i remembered that a while ago i saw a tv show about science and technology that presented a "new" method for eye tracking using an infrared camera ... the idea was that using a led array like the one you made for the finger tracking device you can create an artificial red eye effect. the show is called "Beyond tomorrow" and after a lot of digging around the web i managed to find out that the episode is number 10.
i think that if you combine that with the DesktopVR you can get rid for good of the somehow weird looking glasses and track the user directly. well ... that if the wii-mote camera is good enough.

anyway ... i love your ideas and i can't wait to see applications that will make use of them ;D ... and, and, and ... i hope you'll come with more ideas like these :D

Cheers

Bouncing a bunch of invisible light off the back of your eyeball sounds like a neat trick, but I have to wonder about the health implications about this.  Can invisible infrared light damage your eyes?   I'm sure I've put a TV remote right up to my eyeball and pressed buttons before and never felt any ill effects, but there must be a limit to how much IR light your eyes can withstand.

the easiest way to understand how it works is thinking at a normal video camera that has night vision ... i'm sure that you remember the creepy white eyes ;D ... i think that it's basically the same thing with the wii-mote ...

although it might not work very well when it comes to tv's it might work very well on monitors and in games for pc



i've just realized that what i wrote has actually very little to do with what you said  :( ... i'm sure that it ain't that bad ... i'll look into the implications that big amounts of IR has on the eyeball :)

:wave:

well, i don't know about you, but my parents told me not to point laser pointers into my/other peoples eyes. Although IR leds aren't bright, they still might damage some stuff internelly, kinda like radioactive rays, you can't see them, but they do effect you.

IR IS and WILL ALWAYS BE just heat emition lolz and as i cant seem to see the effect of looking into a heat source (besides the sun) i have to counter your argument ^^

all i could find is this http://tldp.org/HOWTO/Infrared-HOWTO/infrared-howto-a-eye-safety.html and it's not a professional opinion. I did found out that UV light may cause damage to the eye but that's not the case here ... and neither laser which is something totally different from UV and IR ...

even then, you know how uv rays are more dangerous when its cloudy. it could be like that, but hey, what am i worrying about, if i do go blind, by that time they'll have a surgery where i can see again.

yes that is true, in some states its illegal for people under 18 to have a class 2 laser pen. If you do use a laser pen, just don't point them in people eyes, cause thats really bad

Ir LED is not the same as lasers. IR LED's are much much safer.

You wont have a problem.
lol have you even seen this video? http://www.youtube.com/watch?v=0awjPUkBXOU

Now. Who ever brought ideas to this post is a GENIOUS. Because this would allow uses to recive automatic VR desktop feature without wearing cheesy glasses.

Now the only catch; Create a Eyeball recognition program. http://www.wiimoteproject.com/project-ideas/completely-human-computer-interactive-media-center-t226.0.html
