Your videos are beyond awesome and you are extremely knowledgeable. It's a shame you don't get more viewers because you always make learning something fun.

That explosion, got you a like.

Mind = blown. Good video, Roo. These videos are always cool to watch, and that explosion just made me laugh.

It is interesting that whenever I search for how a new technology in gaming works, you come up! Your videos are great, keep it up!

Excellent video! Thank you sir. You just awarded yourself a new subscriber. I must thank you for using the braid song, it reminded me how great it was!

I learned a lot more about Kinect from this video than I did from anywhere else.

I remember before this came out someone was saying, "I'm gonna get the Kinect! It has NO controller!" And I was thinking "NOOOOOOO! YOU HAVE TO HAVE A CONTROLLER! IT'S IMPOSSIBLE WITHOUT!" Ah, the good old days.

Brilliantly made video. I wish you had been around back in highschool when we had to listen to someone droning on about this.

I love how people think when they come onto a video that explains how a complex video games system works there won't be any 'big nerdy words' in it. Seriously people, it's common sense. This was a very informative and entertaining video. :3

Spending my whole Saturday on KZfaq watching educational videos....

This was excellently done. I'm an imaging science student at RIT and you understand how it works at the same level that we do.

got to admit - the Kinect doesn't excite me as a video game tool - but I'm still really impressed with all the technology behind it - the majority of which I didn't realise until watching this video - so many thanks to you mr graywolf person :)

Great video. You explain a lot of stuff to the average viewer. Keep up the good work !

Love the funny presentation together with just technology facts :) Great work!

Music from Braid. Excellent choice, sir. Excellent choice.

the explosion is what hooked me!

Can't believe it's been 5 years since I've subbed to you. this is still great info out of curiosity, is there any intention of making more of these or 16 bit gems? it seems all the channel has become is a talk show

i think i understood his camera explanation better on this video than on the Playstation Move video

I recognized some Fable music in there too. I found it pretty damn awesome.

The explosion made this video so much better :P

I love the Xbox Kinect and I love Microsoft and all of the mics

Your nickname from me is Sheldon Cooper !! You know everything , and you have good style descript it !!! Good Video , Keep on budy

Tbh, I actually learn MORE from YT. Either that or i just fall asleep unaware that I''m sleeping in class.

Braid and Fable music is awesome. P.S. great video!

Oh, after 5 mins, I think you may be right. It's been a helluva long time since I played Braid.

I really don't understand anything he's talking about but I like Roo's voice so it's all good.

Love that Starfleet Academy shirt.

Had a chance to demo it, it is preety cool. Controller is very user friendly.

Good video and Braid's music only makes it better.

Thank you! how could i forget this song when i actually played braid

I appreciate the Kinect more now, thanks to you. But I think the Kinect lacks one of the most important features of all video games: Buttons & Controls.

Wow, this must have took a LOT of time to make, it's a shame that it doesn't have any good games that aren't Dance Central.

As JonTron said about the Kinect camera, 'It's staring at me!"

wow all this technology sounds mighty impressive. what a shame there aren't any games that are attractive to a non-casual audience

During the early-mid 90's, there were games that on the surface looked similar (but more primitive) in the arcade, where you would stand in front of a camera, and it would read your position in the room, and let you interact with the games. Did these use a similar basic system? (They did of course not calculate your skeletal structure, simply your position relative to the camera(s?)).

Had to sub, this guy is awesome.

this technoly brings us closer in creating a human like thinking robot.

I tried it out... It was sooo good! There was no lag for me!!

for some reason after watching this video im actually happy that i bought the kinect

At 6:20 it's Braid. I love that game so I'm pretty sure it is.

just an amazing video., i doubt if even microsoft can come up with such a clear explanation :)

That's it, I'm subscribing. (you had me at the explosion)

Can you explain more about how the sensors measure the depth? Triangular or time-of-flight?

Marie Curie-Sklodowska (Maria Skłodowska-Curie in Polish) is from Poland. I'm Polish and I also live in Poland.

That shirt is awesome.

The explosion must have been season 2 of 24. Poor George Mason.

Yay! Halo 3: One Final Effort. Heard it in the background... +10 epic wins!

very nice please keep posting

k so basic sumary invisible light shines on you camera takes the bright light that looks as close to a human as possible and assigns a basic 3d model to it. that could of been so much shorter

I completely understand it now

CONT: and can use that for things that are unintended by the user like sending marketing blurgs, ads on your computer/ip address, or some robber hard pressed on revenge/murder or stealing stuff. Thats why even if I own an X360, I will never buy or even play a Kinect. Hell, this stuff was why we have people making accesories for the Kinect for this one distinct purpose. I just hope Sony doesnt improve their form of spyware on the Vita to do the same as the Kinect.

i love the fable music

That's cool I always thought the Kinect used LDAR or lasses

Why did it have random pictures of goats at the beginning and played halo combat evolved music on it?

thumbs up if you're an electrical engineering major, or engineering major, and actually understand what he is talking about

I hope we won't have to buy a new camera for the 720

Having to work with microsoft software for a long time i can say i expect the kinect software to have the BSOD

5:28 I think the kinect calculates the depth using paralax not infrared light intensity. (See: uq9SEJxZiUg)

My laptop runs with Vista and I have gotten 4 blue screens in my years with it and my hard drive is still fine.

I like the music.

OK my next Life goal is to understand everything you say in this video lol. I'm actually really interested in this :D

and also how Windows 8 is made for tablets and touchscreens, even though laptops and desktops WITHOUT any sort of touch interface are being sold with it... and let's not even mention the fact that a little while back, Windows 7 (and also 8 i believe, don't quote me on this) had an update that replaced your video card driver with a generic Microsoft one, and (depending on how incompatible with your video card it was) would to FORCE you to do a system restore, or re-install...

@RyutarocKxxx Technically, the OF in that staetment can't count as a word in this sence, but, eitherway, I atill agree with you.

Although I admit that the Kinect is a fairly interesting device, I disagree with it being a 'revolution' or a 'breakthrough'. Considering that Sony came out with the Playstation Eye a couple years ago, which worked on the same principles as the Kinect. It sold terribly, but was, in fact, what the Kinect is. I hope at some point the fans realize this and start calling the kinect something that pays tribute to the Eye.

Hmm, I honestly thought the Kinect units used a TOF (Time of flight) camera. The more I know, the less I actually know.

What is the song at the end of the video after the credits?

Sounds like the music from Braid about halfway through.

good video, even if i'm not interested in the kinect it's self

Why are probabilistic models always used for machine learning?

Is it possible if you can talk in a video about how holographic imaging works?

Well that was a very interesting video even though I'm not that much into technology and info about how they work. Simply because too much complicate information makes brains hurt mine. Good work anyway. Also the EXPLOTION made me laugh very much. It was something very unexpected.

@Zonde32 so then i suppose your going to explain it

@Eatmyassproductions It's actually really really cheap considering the technology behind.

hey its the alton brown of video games!

man you could be a teacher. great vid

FABLE background music :) awesome :)

OMFG Fable music!!! Subscribed

what is whit the eye toy from playstation?

Mr Roo I'm stuck at how the Atari Joysticks work... why'd you have to take it to such a greater level? :)

Exactly, besides I have a windows computer, a PS3 and an iPhone.

so this means that if a ghost was to pass infront of my kinect, it would recognize it as a living person?

Sir, check the date of this video.

How is it hidden? There are multiple cameras in plain sight.

Hi, I have a question regarding creating a program for the kinect. If anyone knows how to program software i would really like to run a program by anyone who has skills in this field. Please leave comment below or email. Thanks

Would it work if you have one arm?

Great. Now i want to play Fable!

So it's like motion capture without all those bits stuck on you.

@xsaneog More like apple. And they tried on the videogame- (console, actually) market but failed miserably.

Dat Fable background music...

Lol the beeping on the 30 second clock is from 24

He clearly said that this isn't a factor. You're more prone to radiation from visible light than from infrared light.

Again. As is with the Move, there's a delay in reading input. This kills any chance of playing any real games and hardcore gamers won't really care about anything like this. I mean, when certain gamers nitpick about sub 100 ms response times, the Kinect's obviously perceptible delay makes it useless.

now what i want to know is, how that old eye toy from the ps2 worked

dose it work on xbox360 old one not slim ?

No, eyetoy was just a camera, Kinect is much more complex. Didn't you watch the video? (And I'm not an XBox fanboy just trying to defend his console, I don't even own an XBox)

Who remembers the eyetoy for the ps2?

Oh yeah... Okay, that aren't Dance central and Gunslinger than

Who looked up fainting goats after he mentioned it? :P

I would love to see mac make a game!

1:19 Whats the Music? PLEASE!
