Is this even Possible?

In the following video, some guy made this game in blitz3d where you use motion tacking from a webcam to move the characters head in the game. Is this real

Yeah, it would be possible if you can load in the images generated by the webcam and track a certain colour that the user wears - so say they place a green sticker on their head, you can do a check for where there is green in the picture and compare the difference in position from the last frame taken.

Yes it's possible, in fact there was a system at CeBit which was demoing a thought controlled cursor which is quite cool, you think it moves, and it works. The possibilites, particularly for people with disabilites are immense.

with physical disabilities ne way, the mentally disabled would have trouble

How would yo do that lol?

i used to find myself trying to look around corners using my real head instead of moving the player
so its kinda handy to be able to do that

but if you are distracted and look away from the screen wont you be looking elsewhere when you look back

yeah...

will someone tell this guy about his green zit problem :))

haha, wow has anybody in this comunity done this stuff?

G Tea: that vid looks fake, to me.

Personally, I'd get Paul McKenna onboard and have the technology work by hypnotising the user into believing that they wanted the cursor to go where I was moving it randomly. And to buy more headsets for all their friends and family.

Who the heck is Paul McKenna

A well-known hypnotist in the UK.

A.K.A. a tosser

kool

fake or not it seems overly complex
its not as if its a facial recognition program or a program that mimics the face by user input

so a very basic set of dots on the users real face (although humerous to look at) would be more cpu friendly (perhaps why hes onlyl got 2 objects and the other ones got a fps ;) )

sort of related.. check out this one. Its using a wii remote.

I'm sure jfk has done something like this before.

the wiimote one is fantastic
2 headmounted ir leds no silly dots for tracking
ok it so far needs the wiimote but it cant be that hard for someone in the joystick biz to make a similar thing

edit:
their is a wiimote add on that once youve slotted the bits in it turns it into a crossbow controller
so as LCD's dont work with light guns are we to expect similar setups for the pc?
id love to have a 'real' gun for fps'ers even though i got used to the xbox controller (due to xbox fps games) i only wsad+mouse now cos not all of my older games support the 360/windows pad

I've modified my webcam for IR light and bought couple of IR LEDs, but the LEDs are too bright for the webcam so i need to cover the LEDs with something or buy a new webcam and leave the IR filter in it and so it wouldn't be so bright.

Sad that webcams are so slow, as seen in the first video :(

faster webcams wouldn't help much. The load for the CPU would just raised drastically as the data need to be handled by something in realtime.

webcams = bad
wiimote type of setup = good
its shown itself to be fast

it just needs to be something adapted to the pc on a more mainstream level

Ross - yep I made a painting tool with PANNOs webcam dll. A TV remotecontrol is used as mouse-substitute (altough you can determine the position only when the "LMB" is pressed).

Tho I agree with big10p, looks like fake since the guy does not only move his head, but also the mouse.

On tutorialninjas.net, it said sumthin about making a lightsaber thing with a download on their site, the bluetooth in the wii mote, and a mac, i think it was. Read it like a year ago.

i make a test ....

?

I'm surprised seeing you amazed by this technology. It's not fake and it has been used for quite some time now.

There is TRACKIR by NaturalPoint;

And there is also EyeToy for PS2 which is similiar.

What's being done in that first video isn't very difficult. The only question is whether you can get video from a webcam into Blitz, and process the data fast enough. Blitz isn't exactly the best choice for processing image data in realtime.

This is possible. I'm using a webcam in BlitzMax for some time now in my Pacman Clone for making pictures for in the hiscorelist. There are dll's out there which work even with BlitzMax examples.

To gain speed in processing all is to use a lower resolution or grid to search for movement or dot's in a special color which aren't used in the rest of the background.

One idea is to use infrared leds, invisible for the naked eye, but visble on a webcam as a white spot and doesn't eat too much power and should be easy to see by a webcam in light and dark enviroments. To try this use a infrared remote, point it at your webcam and press a button, you will see the leds clearly.

I was thinking of a new project with 2 webcams to really locate a position of something in 3d space. 2 webcams can give the computer stereo vision when positioned corectly.

I think sswift was refering to blitz3d.

Balrogsoft used to do an camera motion system, but its now basically defunct, so if there any other multi-OS system availiable ?
