Microsoft Kinect: The AnandTech Review
by Brian Klug on December 9, 2010 3:20 PM ESTLag and Conclusions
So what about lag on Kinect? It’s definitely there, but it isn’t nearly as big of a problem as it’s been chalked up to be. I decided to test how much that lag is by taking an extremely self-deprecating video of myself flailing my arms about in front of Kinect, and inspect the video to see how much delay there is between me sweeping my arm up, and the TV reflecting that change. I just used the Kinect tuner since it’s full screen and does body tracking, and later counted how many frames it took after my hand reached the top of an arc for the image to also reflect the change.
At the end of the day, I measured between 8-10 frames of input lag, which at 29.96 FPS works out to 267 ms of input lag. Of course, that number also includes my Onkyo TX-SR608 A/V receiver, which (even in game mode) adds a substantial and perceptible amount of latency to the whole display chain. For the caliber of games currently rolled out which support Kinect, lag honestly isn’t that big of a deal. I found it definitely noticeable in the Kinect Adventures obstacle course, and somewhat noticeable when playing Kinect Sports and running hurdles, but everywhere else, while noticeable, it isn’t a game-killer. Don’t get me wrong, 267 ms is seriously laggy, but right now it doesn’t matter too much. Maybe when we get FPS titles that’ll change.
I think it’s fair to say that Kinect thoroughly rains on the Wii’s parade, and enjoys a substantial lead over Sony Move if nothing else entirely due to lower out-the-door cost. One of the best parts of Kinect is that you really do only need the sensor to play games - there’s no sets of controllers, camera, or kit to purchase. If you've got a room that's large enough, Kinect is perfect. On the other hand, there's no possible way that Kinect would ever work in the average dorm room - you really do need 9' - 12' behind the TV to play with two people.
The rest of what Kinect does is really just mitigate a lot of the motion-cheating I felt was possible with the Wii, some of which is still possible with Move by holding the wand close to the sensor. Adding real depth detection and forcing players to actually move around has done a lot more to make me move instead of wrist-flick than any of the other motion-augmented console addons did.
Does Kinect breathe enough life into the Xbox 360 to make it last another few years? I suppose, but only for as long as Kinect titles can deliver new and more interesting gestures, immersion, and interaction events. For now, however, I’m having enough fun motion trash-talking people in Kinect Sports to keep me entertained for at least until the next major console blockbuster title.

Yeah, I just meant the 350 part. Referring to it as the 360 S to distinguish it from the 360 Pro makes sense to me.Noriaki - Thursday, December 9, 2010 - link
PS: Thanks for the in-depth coverage. This is the first time I feel like I got a good idea of what having a Kinect in my living room would mean for practical things like where my couch lives.Aikouka - Thursday, December 9, 2010 - link
Brian, have you tried out DanceMasters (DM)? I noticed you commented on how your girlfriend compared Dance Central (DC) to DDR where DanceMasters is actually created by Konami.I own DM and have played the DC game, and I have to say... you'd probably be disappointed in the DM menu system as it is a tad bit harder to control. Way too often I found myself skipping past the option I wanted (as all options move left or right) and you then have to raise your (right) hand to select it. The problem comes when it might see you move your hand out to the right and actually shift your choice over one right before you raise your hand.
The part where I think DM beats DC is the actual dancing. In the demo for DC, I found it awkwardly difficult to pay attention to the way the dancer was moving (left or right, etc) and the upcoming movement that was shown on the right side of the screen. When my brother and his girlfriend played, I noticed one huge trend... we *all* would miss the first dance move after they changed from one move to another.
This is kind of better in DM, because it uses arrows that signify how your hand (or hands) should move in a second or two. There are also circles that will appear on the screen and you must hit them with either your hands or feet (obvious depending on the location). The last movement is the "pose silhouettes" that appear on the left and right side and are green in color. They move to the center of the screen and when the two silhouettes combine, you are supposed to be in that pose. The only problem is that it's not terribly picky on what you do in between these three types of inputs and another problem is that it loves to put circles beneath your feet (so you keep moving), but they're hard to notice. I found this easy to combat by simply always moving your feet.
Overall, there's a huge difference in the style of music between the two as well, which influenced my decision. I've never been a "Top 40s" kinda guy and I've played DDR quite a bit, so I went with the game that had the music style I was used to ( and also considering that I've heard quite a bit of Eurobeat, which DM also has ).
The one thing that was always fun about DC was the "freestyle" section where it shows you as this sort of glowing silhouette and you just do whatever dance you want. At the end, it will play this back to you in a sort of time-lapse video (which you can then save).
To talk about a different game, I noticed some problem with jumping in Kinect... mostly in the rail-based obstacle course. Maybe I was just doing little hops and Kinect didn't register it... maybe it was a problem with the cargo pants (khaki color, so they're fairly flesh-toned) that I was wearing. It was pretty crazy though... at one point I had to duck down, so I dropped to my knees and then needed to switch sides, so I pulled out the Starfox-esque barrel roll! Kinect did actually sense that correctly.
The one thing I did notice is that it is *very* common in Kinect Adventures for it to yell at me about getting too close or too far... especially in the bubble popping mini-game.

I haven't checked out Dance Masters, but I'm starting to think that I definitely should. I think at the time when I originally put together this list of games, that wasn't available and I overlooked it. I'll grab it and maybe update with a page or two.It's interesting how dancing games are quickly becoming something Kinect is very well suited for. I definitely agree about jumping and the clothing choice, I have a pair of cargo shorts that just don't work with most of the titles, and Kinect Adventures does yell a lot about position, agreed.

If only i could use this with my p.c.....ExarKun333 - Thursday, December 9, 2010 - link
I purchased the Kinect soon after the launch and I came to pretty much the same conclusions are Brian. The lag is there, but acceptable. More importantly, the games are FUN. MS did a great job with this launch. The hardware is easy to install and configure, and the games are easy to pick up on. I agreed 100% that the menus in DC are superior to the method in the Dashboard. Maybe an update at some time? :)knowom - Thursday, December 9, 2010 - link
267ms on a DAW would be completely unthinkable in fact most people that play or record music try to stay below 10ms.I'm just using that example as a clear easy to demonstrate reason to why 267ms is a abysmal amount of input lag you can completely rule out music based kinect games as well as any twitch/quick reflex input games or applications.

In the comment about the laser probably being 650-700 nm, that is wrong. 650nm is the wavelength of a normal red laser pointer. Normal IR diodes lase at either 780, 808 or 980nm.Brian Klug - Thursday, December 9, 2010 - link
Hmm it's on the fringes of what I'd consider visible, but 780 probably is a much better choice. I'll update.-Brian

Okay, I am probably the only prig to bring this up, but the distances required seem to be a problem for some not often thought of reasons.9-12 feet of clearance appears to be required, which means the sofa will need to be 15' back (unless you move it every time you fire up the Kinnect).
I would point out that you would need to have a 55"+ HDTV to fully benefit from the 1080p image from the Kinnect playing area, For regular game playing / movie watching on the sofa (behind the playing area) you would require a 100"!!!!! screen to fully resolve the 1080p image that the Xbox360 or a BluRay player is capable of displaying.
For this thing to really work in a robust media environment (and most living rooms) it should have been able to to work perfectly with the user standing 3-5' from the screen.
