The Case for Kinect
The strengths. The weaknesses. The facts. Digital Foundry investigates.
As we move closer to Kinect's November release date, games developers are talking in more detail - on and off the record - about the new motion control system: what it can do, what it can't do, and what we should expect from the system going forward.
Microsoft itself is stepping up its marketing efforts. This week, two articles (one from T3 and another more impressive piece from Gizmodo) arrived, giving us our first peek inside the Kinect camera and giving us enough technical info to banish the somewhat unkind "EyeToy HD" talk that has dogged the internet since E3: Kinect is a state-of-the-art consumer-level piece of motion capture equipment with voice recognition and biometric ID capabilities and Microsoft wants you to know that.
In the meantime, since E3, Microsoft has shown the system working on TV shows, and rolled out playable demos in Macys stores across the USA, leading to a range of Kinect "fail" videos appearing online, along with attempts at other events to deliberately trip up the sensor with the use of baggy black, reflective clothing amongst other things.
Mileage may well vary, but we've been hands-on with Microsoft's demos and aside from an unfortunate experience for Eurogamer TV's Johnny Minkley with racing title Joy Ride, the system has performed pretty much flawlessly. Within the scope of the "experiences" the game-makers have sketched out, Kinect works, and the best games are going to prove compelling to a cross-section of the gaming audience that probably aren't so keen on the likes of Halo, Alan Wake and Crackdown 2, but more in tune with titles like Wii Sports and Wii Fit.
While core gamers fret about whether you can play Kinect sitting down, game developers are busy making titles that are, for the most part, physically impossible to play from a seated position any way: even the aforementioned Joy Ride has you swinging your ass about in order to drift the cars, and gameplay is for the most part structured into "bite-size" components so you don't get too tired, or spend too long on your feet. It's all about energetic gaming in a social environment - elements of the formula that made Wii such a success.
Microsoft released new images showing the Kinect sensor uncased. Four microphones (three to the right, one to the left) account for the width. Multiple PCBs suggest that the device really is somewhat more advanced than you might think and fairly expensive to build. There's a durable motor in there, plus a fan to dissipate heat. Kinect tracks you, adjusting the camera angle for the best view of the player.
That said, an investigation into the perceived limitations of Kinect reveals an intriguing truth: the device itself is merely a vehicle for supplying data to the console. What defines most of its capabilities is the software, and that is in a constant state of evolution. Forgetting this is a big mistake in evaluating the potential for Kinect as a gaming platform.
"Every day the technology and software improves, so we're constantly tuning it," bona fide games legend Tetsuya Mizuguchi told CVG, discussing development of new title Child of Eden. "Nothing is optimal at the beginning of a new technology, but it's been getting better and better the more we work with it."
At its most basic level, Kinect - as a device - offers up nothing more than raw data to the Xbox 360: a traditional webcam-style RGB image, a depth map from the 3D sensor and audio from the multi-array mic. The discussion about what the system can or cannot do is mostly about the interpretation of that data: many of the system limitations are actually software limitations, and software can be improved. Microsoft audits feedback from the developers of Kinect titles and improves this interpretation layer in regular SDK updates, so similar to the console development tools themselves, these will gradually become more powerful as the Kinect-specific elements of the SDK are worked upon.
Other developers are steering clear of the Microsoft tools and handling the raw data directly, as Blitz Games CTO Andrew Oliver - currently working on a Biggest Loser fitness game - revealed to Gamasutra this week.
"There are various technologies involved. Some people are using a skeletal system, and it takes a little bit of time to calculate. It's only a split second. We're actually using a different masking system, which can tighten things up," Oliver says.
"But this is all software-based, so where some people might see some little cracks, they're easily fixable by software. That is, the camera fundamentally works and gives you the input; game designers are running forward in a completely new area and learning this stuff. It's like any console. The first few games will look like nothing compared to second and third generation."
Lag in E3 Kinect Adventures was around the 200ms mark...
It's interesting to point out that Oliver is dismissive of the inherent latency built into the system.
"It depends on what technology you're using. I have seen a few games with a bit of lag, but that is the software choice of the creators; they've programmed it a certain way, and they'll come up with new techniques," he says.
"We will tighten and tighten it. There doesn't need to be a lag. We can get it down to maybe two frames behind, which is pretty insignificant; you won't notice. We're just learning new tricks. Ours is pretty tight."
It'll be intriguing to measure latency in the final version of Oliver's title because as regular Digital Foundry readers will know, a 30FPS game using a conventional controller typically has 100ms/six frame latency at the minimum, and that's without any Kinect processing.
An additional two frame lag is still within the ballpark latency for many pad driven games, but as discussed in our E3 hands-on, the sensation of latency with Kinect is increased by several factors: firstly, the human body as a controller is nowhere near as "quick to respond" as your fingers: the human body itself is "laggy". Secondly, gesture recognition incurs some pretty severe latency, most noticeable in jumping - and there's a lot of that in Kinect Adventures and Kinect Sports, to name just two titles. An on-screen gesture-driven animation can only kick in once the software has figured out what you're doing: it's not 1:1.
In truth, the two-frame claim also seems at odds with the realities of the Kinect set-up - processing the optical feed, producing the depth map and transporting it over USB 2.0 incurs a base-line latency even before the game itself gets its hands on the data. And of course we need to remember that Kinect itself only scans at 30Hz - in pad-driven games, latency leaps from a minimum of 66ms to 100ms when frame-rate drops down to 30FPS from 60FPS. A lower scan rate absolutely translates into higher latency.

There's definitely room for developers to fluff their lines, but when they get it right, you can expect the results to be magical.
As far as consumers are concerned, the pre-order numbers give a decent indication that people see the potential of the device, and like the idea of a new motion gaming "experience" beyond just a hand-held controller stick. That's probably the fairest measure of whether it will be a success or not, most of the commentary about it on the internet is coming from people who aren't really being targeted by either the activities being shown or the types of games... Not surprised that it polarises the press/commentators a bit

Except the Wii very likely won't be £180 come November... I can almost guarantee it. Nintendo have already admitted Wii hardware sales are slowing down and that usually means a price cut is needed to 'stimulate' sales. With competition in the form of Move and Kinect this autumn it would be very stupid of Nintendo if they just sat their and did nothing about it.
Kinect sounds like an intriguing concept from this article but I think the hardware is not advanced enough to offer the kind of experience that I was hoping for in terms of interactivity and responsiveness. No amount of software tweaking will overcome the pathetic 320x240 (SNES/Megadrive/Amiga resolution, fact fans!) scanning resolution. I suspect that a generation or two of hardware refinement will lead to a more impressive product (and hopefully a cheaper one too!). For now, I'm happy to wait and I'll give this one a miss, thanks.

How many fit or dancing games can they do before consumer gets bored ?
Wonder which comany will corner the dance Kinect market ? Thats the main one for devs....
The rest of the games look poor.
Also, for fighting or any action game, the Kinect camera is only 30 FPS and MOVE is 60 FPS at same resolution with less processing lag, so the wand will always be better for any action game with a club / sword / light saber....

I'm sure a lot of the games will be fun, but it very much seems to occupy the "in the cupboard until you're drunk" space that most Wii's seem to be used for.

Just as there remains a similar very definite sense that Xbox Live is a walled garden. This approach so far, has proven to be ok, until they want to offer a broader range of services, and then things get held up and disappointingly, do not progress in particular directions.
While on the subject of "fact or fiction", for Kinect, do you need 6ft of space between yourself and it, to use the thing? I read through, but I didn't see that covered in the article.

So I want it to be a mega success for two reasons: 1) brand new exciting types of gaming experiences, and 2) the more people that play games - casuals, hardcore, old women, foetuses, etc - the better.

Some form of physicality in the control is the problem - it's useless when your tired, stressed, hurt, physically unable, in the dark, feel lazy, can't find your glasses, want to sit back or lie down (as most people do when playing games) etc etc...Kinect has more problems not having a physical tool to control with, then not!

Let's hope there will at least be some non-casual titles coming up later that will find new and creative ways to make use of Kinect, because while it's unlikely that anyone is ever going to convince me to move furniture aside and stand in front of my TV looking down at it from a less than ideal angle in order to play a game, it certainly seems like a technology that ought to have some kind of potential for something a bit more inspired than dancing and jumping.
Meanwhile I'm thrilled that Move is turning out to be a slightly more advanced and precise Wiimote knockoff - I can't wait to play shooters and assorted other action/adventure games with pointer/motion controls.

Why are people still talking about being excited by Minority Report control, its already been shown that it is nowhere near that in both terms of speed usability.... people are still expecting it to be that good, i just don't get it.
Anyway, I still think this is very useful tech for the Future, and perhaps in 10-20 years it could be exactly what people are wanting, but credit to MS, they have spent alot of money on it, and only when companies spend lots of money on something, generally can it get better results. So even if its rubbish and doesnt do what people want, its at least had people and resources on it to help improve it the next time around (as long as its not a disaster and they drop it).

Given the market it's aiming at I wonder why they included all the expensive depth sensors at all. The casual market isn't exactly discerning and I reckon a sufficient marketing push behind a straight up eyetoy 3 years ago or even today would have served them far far better.

No matter what we think on Eurogamer, or elsewhere on the internet, I imagine Microsoft have spent a fortune on 'price discovery' marketing research and will sell more Kinnect than armchair (deskchair?) pundits give them credit for. I think if Microsoft bundled some kind of dance game with the system, it woul be a Wii Sports like killer-app; although I suspect it's going to be difficult to get Harmonix to bundle Dance Central.
As a long-standing hardcore-gamer Kinnect might not be my cup-of-tea for every game I play, but I plan to order one simply to jump about with the kids on Xmas day (annoy the in-laws) and beyond ... unlike some posters above I'm not stuck to my couch and don't mind looking like an total arse either.

The one aspect i am dissapointed in them is their competitiveness, in the past they've gone head on with their rivals, and E3 09 for me was one of those situations where Ballmer should have looked at the Sony demos which to be fair were super responsive, and said to someone 'you have to match that aspect, or we're not launching' But instead they've taken the angle that they're so different and new people won't be looking at things like responsiveness and jumping to conclusions...they truth is they do/will, and for some good reasons, beleiving it before you see it is never a good strategy, especially when it's pricey.
At present this is a 'sit there and wait until they prove it is what i want' situation...so perhaps they do that in a year...that's not a great way to launch a device, the uptake from core gamers is going to be very slow....and that could/will imo be a very painful period for them, and the developers who could be hung out to dry early on.
I think one thing they should do re the core is...not needing to make a game at all, make a simple tech demo to show how fast it can process and respond to an arm being waved up and down fast on a screen...because we've not seen evidence of that, we've heard talk of it.

One question about Kinect does arise ... and that is of multi-players on same Xbox, how does it work?
I know Microsoft are updating dashboard in November, for two key reasons: (a) adding support for Kinect, and (b) offering Xbox Live Gold Family Pack http://www .xbox.com/en-US/live/familypack, with Family Center to manage memberships. Are they going to make it easier to log four family members on at once to play games and capture stats and scores (individually as per Wii Mii) or are they going to keep as-is where one player is logged on to Xbox Live (and gets all the achievements and game points)?
Edit: bloomin' HTML tags, and added URLs.

I'm not interested until the price is £80, with an amazing and highly rated title.
I'll likely not buy in until there are 10 games worthy of my cash. They're damn right that this is like a new console launch. It's one where I'm not going to be an early adopter.

I think Kinect could be fantastic if it works properly but everything I've seen so far suggests it isn't quite there yet. MS should probably delay it to work all the kinks out and make sure it works perfectly at launch but of course they won't. I predict a lot of frustrated consumer stories and many more 'Kinect fail' videos on Youtube after launch.

This is very important as the IR sensor is only going to be returning gross "shape" data for processing, whereas finer detail must come from the regular camera with all the expected caveats that entails. The IR part may not be subject to variations in ambient lighting conditions, but the regular camera surely is and that's something that's going to be of interest to actual end-users.
As Richard points out, only returning a 320x240 depth map doesn't give developers much data to work with, so I'd expect more finessed input -like facial recognition- to rely heavily on the normal optical camera. Much like Move, Kinect's real power is the result of multiple sensor inputs being composited together to give the an overall result higher in quality than any single component can offer.

Being an idiot doesn't hurt apparently.
The CPU was removed to make sure the software could be modified and updated a lot more frequently and give devs their own way of playing with the data. Didn't you read the article.
WIth the CPU it would have had almost zero impact on games and everybody and his dog would include some kind of Kinect features. Ovbiously MS has chose to use Kinect mainly for new type of games. It will do very, very well in the casual space. They chose that path. If you are hardcore and prefer a pad... no prob. Don't buy Kinect. You won't buy Move either BTW because that also offers nothing over a real pad/mouse.
Kinect and Move are no competitors. Move is competing with the Wii. Kinect is trying to do something different.
"so it may be for a next generation version of kinect, because according to the DF article it seems hardly possible "
It is possible... you just have to be close to the camera.
"Interesting that there was no mention of the awful MS demonstration last week where Kinect Sports totally failed to pick up the models movement properly"
If you would have bothered you would have seen that there were about 100 other demos at the same venue that worked correctly.
"It may be unkind to call Kinect Eyetoy HD, but also clearly untrue. Since when is 320x240 HD? "
HD has to do with display... not with reading a 3D point cloud of your body.

I fully understand your point, but if you have a million selling game and 1 out of 100 is going to get a totally non usable game at some point (and remember these were set up in more perfect surroundings than peoples homes), i suspect that is still not a good return.
I appreciate i am over simplifying the point, but as someone else said, if the Kinect units are tempermental, then it will result in many unhappy users/youtube videos and overall will damage MS just as much as the RROD. If your building a brand and you want people to continue to buy into that brand, you have to be careful what you release is going to work (not saying it wont - just saying there are alot of issues that dont seem to have been resolved yet).

EG Members Response: "I'm angrily not buying Kinect, and it isn't capable of anything."
Personally, it's exciting potential, but I'm with a lot of people in that I haven't seen much of it with the current crop of games. However, these are launch titles - and if I remember correctly, the launches of the Wii, 360 and PS3 were all plagued by the same issues. Aren't most launches?
Of course, that's not to say it will definitely get better, but I can only see the potential going up from here.

Therein lies the main problem. Both of these types of games are things one can do in real life, without the need to pay extra and hook up to a gaming console. Games are not meant to be replacements for real life activities such as exercise; that'd just be fooling yourself. Games are supposed to create and mold new worlds, storylines and the like-- what Kinect represents is not gaming, but a pale, poor, inferior imitation of real life. Thanks but I like to keep both things separate.

People like that the game gives you a program and feedback on how many calories you burned. The gamey aspect gives people more motivation to put in some extra effort.
Gaming is not only escaping into another world, it is perfectly suited for enhancing "normal" activities.

You must be right, having an extra DEDICATED processor could not possibly improve the performance.

For not reading the article and totally getting the reason wrong why the processor was removed yes you are.

1)Its not what was promised ....no dedicated processor ,SD camera ,etc.
2)The E3 2009 was smoke and mirrors ,as I told back then.
3)Some features as scanning real world objets to play with them in games are a long way from now...
4)It kinda works ...with lag ,limited input options etc but kinda works..
5) It has real potential for a very few genres as golf games ,but its completely useless for a good numbers of genres.
6) Playstation Move is the best of two worlds ,the most accurate controller ,with the augmented reality stuff and voice and head tracking capture of the camera based efforts and the accuracy of the sensors on the wand. It can also be patched very easily in lots of games ,whereas Kinect cant.
7)Price point of Kinect will definitely hurt it. Move has a better entry point.
8)The marketing push is what will give the products the initial push ,but I thing the mouth to mouth will hurt Kinect in the long run.
9)The worst thing of Kinect is the lack of a proper remote controller. Without an analogue stick it will be absolutely impossible to see a game where you have to actually control the character in an open environment.

If i remember correctly, Long time ago. When Kinek still called PROJECT NATAL. (its all caps right?)
There a real Burnout game that Edited to compatible with NATAL.
Those that tried it, can play burnout with seated. Use legs as accelerate.
Maybe NATAL was 640x480 + CPU? O_o a lot powerfuler than Kinect.
EDIT:

What will be tested will be the imagination of developers, and their abilty to find a way to make kinnect fit into a game in more than the most basic and cursory manner.
I'm intrigued how kinnect could work in regards RPG's. For example, if you look at ME2, the two options are really rather basic. It is possible to say something in a real life, which would could be construed as bad, but would be mitigated by tone, body language etc.
Imagine ME3 where kinnect could read the tone of your voice, your body language and how you reacted. Clearly, we're years away from that, but thats the potential in a full body peripheral. I think its exciting, but as i say, the real focus will be on developers. If this fails, i think MS still have a winning technolgy they can sell to TV manufacturers and Sky for example. No more clumsy remotes, just hand waves. How it does as a games technology, thats up to developers.

Although it might seem like both Move and Kinect have parity with regards to borrowing processing from their systems, the difference between a symmetrical CPU Core (of the 360) that will randomly cache miss, versus an asymmetric SPU core (of the PS3 Cell) that has local memory that shouldn’t cache miss, is going to limit the amount of optimisation for Kinect quite quickly; even if developers program their own libraries.
The stream processor design of the SPU cores, and their ability directly access the data-bus packets on the ps3 independent of the PPU, means that even issues concerning data-bus bandwidth contention can have good(isochronous) solutions for Move, where by contrast they are exacerbated and unpredictable on Kinect, because of the cache missing and the symmetrical core threading.
Though this makes no difference to the casuals, the core gamer who invests in Kinect and is waiting for a low lag core experience is highly unlikely to get what they are wating for.

WiiMotion Plus is certainly not sub-millimetre accurate like Move, and Move is less likely to suffer loss of control (like the E3 Zelda Demonstration) for three reasons.
1. Handling Bluetooth (electromagnetic/radio) interference by using forward error correction is less problematic when you have CPU power to burn, like the ps3 does with the CELL.
2. Move uses image recognition for pointer tracking so it doesn’t broadcast this information by Bluetooth and so it isn’t susceptible to the interference the Wiimote does when doing the same task.
3. Move uses a seperate bluetooth transmitter for the subcontroller and so it doesn't put all its eggs in the one basket, like the wiimote & nunchuck controller(which share one transmitter).

I do think a lot of people are underestimating how well Kinect will sell, even at that price point - and of course it gives MS latitude to price drop over the next 18 months to encourage uptake. For a lot of partners, parents etc of people who already own 360s, Kinect is like buying their own console, so the price is less off-putting than we think.
Lets put it like this, my wife took a look at the demos, Dance Central and Biggest Loser and immediately said "Right, I don't need my Wii anymore". Her birthday's in November and the pre-order is already in.
Although if she thinks she's getting anywhere near my 360 during the biggest release quarter of the year, she has another thing coming

Move just looks so much more responsive and flexible and I think having to use a wand is a small price to pay for the amount of accuracy it achieves.
That said, I don't think it'd make me rush out to get a PS3. This sort of technology always needs a 'bedding in' period and Move may not even be well utilised within games yet.

1) A fast intuitive UI interface for navigating the dashboard (similar to the one in the marketing PR video from E3)
2) The system being used with a controller as well.
3) Some kind of mapping?scanning tech that shows the object you are holding used in the game and moved 1:1 with your movements.
4) Any intelligent/ revolutionary use of Kinect in a game franchise/genre that I hive a shit about (not kinect sports or minigames)
That shouldn't be too hard to come up with now should it?! Until these events happen I will happily give it a go but I won't part with any of my cash.

Sony have been a bit smarter in my opinion by not relying on Move to sell machines. Also all Kinect games are full RRP where as most Move games are not and with a cheaper entry point may help Sony.
I just thisnk core gamers are going to be left out in the cold with Kinect and the dumping of Kinect support for Fable 3 shows that. They may want the casual crowd but what if they dont bite?
MS are playing a risky risky game and it oozes arrogance of the position they currently have as the number 1 HD console.

but again with only a 30 fps camera and a low resoulution 320*240 scanning resolution for the 3D sensor bar...well people should forgot and stop dreaming about minority report controls...

If they can convince the mainstream I don't think price will be too important. It can be marketed as something new and different to the wii. It doesn't have to rely on tech speak like speed, accuracy, and power to convince people it's better than what they've already got.

I think the dance game looks about the most interesting (even if it isnt directly showing your moves on screen, but showing you success or failure).
Timing will be the key, because if a new range of fitness and dance programs come out on other platforms, i think this will eat up any large potential Kinect may have of persuading people to move across (for those looking for fitness/dance).

@DoctorFouad if you read the Gizmode article linked from this one, you will see that the 2 player limit was a design choice, not a hardware limit. Kinect can see six users at once (but only 2 playing at once). Once software is optimized there is nothing to stop MS from patching the system to allow more active players. That is why they went for the software soloution instead of the fabled 'bone chip' that everyone went mental about.

If the custom silicon had been a stream processor (like an SPU core) with low latency memory then Kinect could have eliminated most of the lag, used a higher resolution camera and capture rate, and would have placed as little demand on the data-bus as a wired pad or arcade joystick.
As it stands Kinect has to transfer (320x240x24bit x30frames ~= 6.5MB per sec for each camera, equating to 13MB/sec (2x6.5MB/sec) of raw data when both cameras are being used.
Assuming Kinect internally uses either lossy or lossless compression (at around 3:1) we are probably looking at around 4MB/sec of data-bus traffic just to send the data to main memory without doing any image recognition on a Xenon core. Moving the data back out of main memory into the CPU cache for processing naturally uses more data-bus bandwidth and can potentially cache miss on each access to main memory which is a big problem for lag in Kinect.
So going for a (symmetrical core) console software solution isn't likely to be anywhere near as good as a stream processor in the camera with its own upgradeable software.

Phone cameras far exceed the specs of Kinect, with some even offering 120fps modes. And stand-alone digital cameras are so cheap, I don't think anyone would object to paying a tiny bit more for 3 megapixels sensors or higher. Combined with a wide angle lens, and software that is selective about which part of the sensor array it draws data from, it would do away with the need for Kinect's motorised base also, and allow for greater precision when doing something like tracking only one body part, or scanning in an object. It may even make the idea of the virtual keyboard possible.

I agree with the comment of vizzini, having a hardware solution in kinect instead of relying on xbox360 CPU doesent mean at all that this hardware cannot be programmed and its performance optimized through time with an evolutive software-formware upgrade (like any other upgradable firmware we find on a lot of consumer electronuic devices today, even some TVs today have upgradable software)
Actually this argument of why Microsoft abondoned hardware signal processing solution for Kinect (to allow flexibility in software, so it is more efficient) is a pure marketing false argument, it is totally the opposit. The real reason is very clear : COST, it is less expensive to produce Kinect without an internal processor, thats all, it is as easy as that.

I think Microsoft didnt go for a higher res camera for 2 reasons :
1/ Cost : yes even 3$ + cost is a considerable ammount of money for any enterprise wanting to sell millions of those devices (you do the math lol)
2/ less processing intensive for the 360 CPU, processing 1.3 megapixel worth of data at a rate of 60fps would be reallly computationally expensive + even USB2 bandwidth limitations (considering you have also to send the 3D sensor bar signal data)
3/ for the sensor bar being low res 320*240 instead of 640*480 thats really due to costs.
Kinect 2or an equivalent from the competition (Wii 2 ?) if it ever happened would be very interesting with an HD camera + HD 3D sensor, I cant wait for this technology to develop...But the actual Kinect it is clear that the technology is very limited for any finger recognition-reliable interface system...it is like the Wii motion sensor capacities, technically very limited (compared to motion+ or Move) but software (wii sports, wii play, wii fit...) did the rest...would software do the same for Microsoft ? I dont think so...but we will see...

Thank you nintendo and sony for ensuring your product have met a certain level of quality and finish before launching.

Personal training software(martial arts or weight lifting technique for example)
Cricket
Tennis
Golf
Acting
Dancing
Now some of those are quite appealing to me (not acting or dancing!) and could really work well, all are really simulations, not games.
The one positive I can think of is getting coaching from the system to improve technique which would be of great benefit if done properly.
If I were to get this system, I doubt I would get any kind of software anywhere near the traditional game type stuff that seems to be all I can see at the moment, anything like "holodeck" type experiences that may end up being possible look a long way off yet.

Which is absolutely great. Up until you realize making games for an HD console isn't exactly cheap and developers or more accurately 3rd party publishers don't like to take risk. Tie that into the fact that MS relies mainly on 3rd party developers to bring in the good games and I would say we may have a bit of a problem.

I said nothing about lag - merely the number of players. Doctorfouad got it spot on with cost. The onboard processing for the video would have been cost prohibitive for a unit with Kinects purpose.
Of course, us interested in tech think it's purpose is to be a full body motion capture suite for home use (and how I'd love for someone to develop some film effect software for Kinect), but for MS the purpose of Kinect is to chase Nintendo's casual audience. MS are following the lead of Nintendo is using the most cost effective tech possible to get a price point that the masses would be happy with (well, not quite it seems, but nearly).
The audience MS are aiming for are not concerned with the fine grain control a full spec system would have given - they merely want to flap around infront of the TV and see there actions mimiced (and who can blame them)!

@ DoctorFouad: Regarding cost, I would have expected MS to be happy to ditch the motorised base if they could. No webcams have them to my knowledge, but would benefit from them by the same amount, so I'm quite sure that higher-res wide-angle webcams are preferable even if people don't have the bandwidth to make full use of them. A benefit of wide-angle is that you can also be closer to the camera instead of standing several feet back, without fear of your head and feet being cropped out. And you can have more people in view of the camera at once, if this was to be of any use to a game.
More picture data could well exceed what the Kinect software is capable of processing, but a prop that's easy to spot without help from the IR sensor could provide the precision that Move boasts, and the software could be selective. For example, the Nokia N8 has a 12MP camera and can record 720p video. There's no optical zoom, but the phone can use a small part of the 12MP array to enable up to 3x zoom without the picture becoming blurred or blocky.
Thinking about it further though, maybe the IR sensor has some optical issues which prevent it from being reliable at higher resolutions. Perhaps the emitter becomes useless at a wide-angle, as presumably it is just an LED. Then again, remote controls work well enough if you bounce the beam off of a ceiling or the wall behind you, so I'm not sure if that's it.
I'm hoping Kinect will be like the 360 itself - 720p and 1080i back at launch but capable of 1080p and several extra VGA resolutions later on. Maybe 320x240@30fps is a temporary deliberate software limitation. But that motorised base suggests otherwise, and so I'm not sure if I should support this early version of Kinect. I quite like the voice recognition side of it too, but will anything other than Kinectimals and the dashboard support it?

So why did they mislead everyone in the original E3 presentation of what it might do?
And why do we have Peter saying today that Kinect can do core games?
By using the words “can do”, I think that means that Microsoft currently aren't working on any at the moment, and the statement seems to imply that a low lag core game experience will be available on Kinect in the future.
For technical reasons already commented on in this thread; the absence of a stream processor (in either the Kinect's camera or the 360 CPU) is a big problem to produce (consistent) low lag image recognition controls, especially if the 360's data-bus, memory and CPU is being thrashed by the demands of a AAA game's data and models.
Microsoft can't have their cake and eat it; Sony have taken enormous flack from the stalwart PC developers for many years about the learning curve required to develop for their PS2 and PS3 consoles that use stream processors.
But now that the 360 or Kinect camera really needs a stream processor core, to do the task they showcase @ E3 2009, they want us all to lower our expectations and trust that optimizations on their symmetrical core system will achieve, what is most likely impossible; when working with a game more advanced than Duck hunt.

Um...marketing? To spoil the party for everyone else? Because it was initially going to be a different spec? Because console manufacturers have been doing this kind of bullshit spouting for years!!
It's just part of the game. Maybe they thought they were going to be able to produce the Kinect sensor bar they wanted too, but realised it would just be too expensive. The past 9 months have been expectation management from MS and it's affiliates. They know they can't produce the tech they wanted too at the mo, but are probably hoping it will be good/successful enough to warrent making it an integral part of the next gen console (hopefully meeting or exceeding the planned original specs).
"By using the words “can do”, I think that means that Microsoft currently aren't working on any at the moment, and the statement seems to imply that a low lag core game experience will be available on Kinect in the future."
It's possible that 'core' games will use it in the future. I think MS's initial target is the casual market, but someone will use Kinect for some part of a core game. It's not good enough (at the moment) to make a full body FPS, but it can be used with the pad for the fine control.
Just out of interest (still towards you Vizzini) are you going to buy one? The more I read/see about it the more I think it may be worth £130 (even if it's not what we were all expecting/wanting), but I really need to try it out.

As a pointing game, a game enhanced by rumble feedback of the tempo and a game where instant button response smart bomb usage can be critical for a perfect run of the level, it's a game far better suited to the Wii Remote and Move.

Did I have fun? Yep - it was indeed lots of fun and I can see it being more involving than Wii or Move, but was it worth £130 of my hard earned cash?
Absolutely not. I already have a Wii, an although the Kinect experience is good, it's not THAT good that I'd ditch my Wii and start again.
Furthermore, I had issues with the lag and the rom required to play in. Forget the camera feild of vision - it's the jumping up and down, leaning and swaying about. They had huuuuge 'living room' areas that were optimal for the type of stuff th Kinect does, but far bigger than mine, and certainly bigger than a lot of teenagers bedrooms!
Lag was definitely there. IN Kenectimals, I never felt like I was actually in control. When my ghostly hands appeared to stroke and tickle my pet, the seemed to have a life of their own unless i slowed right down.
Joy Ride was fun, but I always found I was never truly in control. Kinect Adventures felt the most responsive, but I never seemed to react in time to avoid things - I felt quite frustrated at the end!
Sure, if the software improves, and I'm sure the type of game will too - but there's no way I'm throwing £130 notes down to add this to my XBOX 360.
I'm just waiting for the first reports of people coming through their floors after jumping up and down playing Kinect games!

However, it's hardly a criticism you'd just level at the Kinect - PS Eye, Wii Fit, and any number of dance mats have the same issue!

The PS Move and Wii dont have the same issues at all. All of the movement is done with the use of a control unit, which can be used by people in wheel chairs and disabled people in general. The majority of games are controlled in this way. However Kinect is the opposite of this where most of the games will be controlled with full body mapping and you having to stand up to control the on screen character etc. How many of these units will be miss sold by retailers. As a retailer myself, I can see this as being a bit of a PR own goal by Microsoft. Once Kinect is released and the main media pick up on this aspect, I think it'll become more of a problem. Many disabled gamers will buy Kinect, not knowing that it cant be used sitting down or with it having problems picking up the mapping of the full body because they use a walking stick/crutch. The Wii and PS Move can be used with one hand to overcome this problem, Kinect cant. I may be wrong but I cant see it.

Plus I agree with what NotSoSlim is saying. What should happen when Nintendo drops the price of the Wii console during the holiday season (such as from $200 to $150 in North America, which I currently live in; somebody will have to figure out for me on what the prices are in the UK & Japan)? Most people will most likely pick up the Wii. Plus Microsoft is stupid for alienating their core fanbase all for a unknown & untested product which may or may not work properly at all. I hope this thing bombs so that Microsoft will look incredibly stupid & will go back to developing games which made their fanbase popular this long into this gen.
