Kinect Hacked, Adafruit Bounty Won 262

scharkalvin writes "Adafruit has announced a winner to their bounty for an open source driver for the MS Kinect. From the article: 'We have verified that it works and have a screenshot from another member in the hacking community (thanks qdot!) who was also able to use the code. Congrats to Hector! He's running all this on a Linux laptop (his code works with OpenGL) and doesn't even have an Xbox!'" We talked about Adafruit's bounty yesterday.

    • Depends on how the hacker did it. If the hacker only released a driver that works without altering the Kinect module in any way, MS can say what they want but they don't have much legal standing. It would be a case of reverse engineering which is legal.

        Why the hell would they have any standing if he did alter it? It belongs to him, not MS!

        Hell, he could pull it apart, rewire it, reflash things...

      • That's not true at all. By communicating with the Kinect device over USB actively you are using the software within, and therefore bound to a SLA to use such software in the device(at least, as validly as a SLA would apply to any other use of software like the more common screen+keyboard use model).

        Kinect is net positive and not sold at a loss.

        • The hardware isn't sold at a loss. There was still a bunch of R&D dumped into the project itself so it has to make X amount of revenue over it's lifetime before it truly turns a profit. Of course, they are shooting themselves in the foot if they continue to release mediocre games that barely get beyond the novelty of the device itself. I think we've all learned our lesson from the Wii this time and any minor flaw that is in the product right now is probably going to continue to stay there.

    I've always wondered about that statement - did Microsoft really mean people hacking Kinect the hardware, or did they refer to the new round of cracking going on in the Xbox360 community after Microsoft rolled out the Fall Update?

    After all, iFixit's tear down doesn't reveal any anti-tamper mechanisms - no potting of circuit boards or anything. Unless they meant firmware hacking to try a USB jailbreak for the 360, but that's simple to do without needing a $150 piece of equipment.

    The Fall update did bring out anti-modded-Xbox protection measures. Backup games fail a new check and the results get reported back to Microsoft, who can institute a new round of console bans (but only if you're stupid enough to connect to Live with your modded Xbox360). I'm just wondering if some new PR person got the explanation all jumbled up or something between the engineers, legal and PR made a very interesting game of telephone.

    I can see how going from "The software update we rolled out for Kinect contains new anti-piracy measures" into "Microsoft takes strong measures against those who tamper with Kinect". Or how a simple query by someone asking for drivers to Microsoft gets turned into a request for the Xbox360 software itself leading to silly statements. Add in 20 layers of management that the message gets filtered through and it's what you end up with.

      What the Kinect does have is anti-cloning. The Kinect cryptographically authenticates itself to the 360 (but not the other way around, as far as I can tell). In other words, it should be very hard to clone, but this doesn't affect efforts to use it outside of the original Xbox platform.

      It seems to me like the people in charge of those Microsoft PR statements don't really know what they're talking about. Sure, there's some "security" around the Kinect (in the general sense of anti-cloning and associated Xbox updates), but as far as I can tell, no effort has been made to prevent DIY use like this. Getting it to work was comparable to getting any other proprietary USB device to work: an exercise in reverse engineering and traffic replaying, but there were no deliberate obstacles along the way.

        Anti-cloning makes more sense than anything really. What does microsoft REALLY care if you use a kinect with your Linux PC? Or even your windows PC.

        They would, however, want to stop people selling knock-off kinect peripherals. (Whether they should be able to even do that is a separate question, but at least one can see why they'd be motivated to.)

          Microsoft probably cares very much if Kinect sales are not perceived in the marketplace as indicative of the Xbox 360 Kinect-using market, since the market penetration of the Xbox360+Kinect combo is a point to use in getting devs to make games for that combo.

          If one person does it, sure, they don't care. But if it is perceived as being widespread, they certainly care. Which means if it is being covered in a public forum with substantial exposure, they have a strong incentive to respond to it.

      I guess the problem might be replacing Kinect with a different device presenting itself as Kinect to XBox. This way you'd gain unfair advantage in online games - where your fitness, physical condition and body momentum would restrict you normally, you could use, say, a key to deliver lightning fast kicks, or duck to the ground faster than gravitational acceleration would normally let you.

  • What'll you bet that Microsoft rushes out a new, less hackable version. There aren't so many of these in the field that it wouldn't be worth their while. Or are they just planning on using patent takedowns to make it illegal to work with the data stream produced by a Kinect box?

    Which brings up an interesting (to me, at least) topic. Once you buy a product that legally implements a patent, aren't you implicitly granted a license to use that patent? To me, if you have, for example, a license to have an ex

    • Generally licenses state that they are non-transferrable. Meaning they are given for a particular implementation of a work. For instance, you don't license the account, you license the software to access the account (which may contain a license forbidding modification of that software). As far as codecs, the same applies. You are not given a license to the patent, but an implementation of that patent. Re-implementing requires a new patent license.

        I get that, but I'm not sure why the patent office allows it. It's anti-competitive, and double-charging. Sure, if they can get away with it, they will.

        In the case of exchange, I'm licensing both pieces of software. Who's to say which piece implements the patent? At some point interoperability demands that wire protocols be implementable, and as long as I'm a paid-up exchange user, I shouldn't have to pay again to implement it.

    This guy is on the way to solving the three main problems of personal robotics:
    1. Indoor localization (figure out where you are inside)
    2. Indoor navigation
    3. Table top manipulation

    There are already open source software packages for all of these items, but they require very expensive laser scanners (starting at 5K a pop). Most of these lasers only scan one row at a time, which means that for situations where you want 3D, you have to tilt the scanner up and down. This is a hassle and leads to slow scan times, which reduces the responsiveness of the robot.

    For indoor localization, what you really want is just a line of points at a fixed height (you could extract one row of Kinect depth pixels) that you can feed to particle filers to figure out position in a mapped space. You might also be able to use opensource SLAM software, wheel encoders, and a Kinect to make 2D and 3D maps of indoor environments.

    For indoor navigation, you can use 2D navigation planners to figure out plans through maps, and then use indoor localization to follow the plans. The Kinect can serve as an obstacle detector in addition to the providing data to the localizer. For example, if a person or animal jumps in front of the robot, the Kinect will sense it, and allow the robot to stop instantly and plan a new route. With a tilting laser, the reaction time would be slower, because laser might be in an orientation where it does not see the obstacle.

    For table top manipulation, the Kinect can provide a point cloud of the objects on the table. CV software can remove the background (table, wall, etc.) and then detect the objects on the table. Once this is done, motion planners can plan a route for an arm or other manipulator to pick up objects on the table.

    Once we have all three of these systems, it should not be all that hard to link them together and start actually doing useful things with robots in our homes. Even just the first two would make it possible useful cleaning and sentry robots.
    • Another very cool application would be a 3d object digitizer (say you want to put a 3d model of your own face into a video game). Instead of building a 3d model manually in e.g. 3d Studio Max (extremely laborious), you just turn the object over a few times and it combines the visual and depth fields to make a 3d, texture-mapped model of the object.

      This is somewhat possible without the depth field, but vastly more accurate (and easy) with it.

      • Another good idea. I'm not aware of any opensource 3D model generators, but I think you might be able to find one/write one. You could have spinning turntable on which was placed (although this would be a hassle for people) or have some kind of spinning ring with the kinect on it.
        • by am 2k ( 217885 )

          It should be pretty easy to use inter-frame correlations to scan an object in 3D just by rotating it in front of the camera if you do it slowly enough. The only problem would be that your fingers would be scanned as well. You'd probably have to do two runs with different finger positions and combine them.

          The only possible caveat would be the depth resolution of the camera. From the video, you can see that there's a pretty large minimum distance, how accurate is the sensor at that range?

      We theoretically approach useful home robotics, and your first thought is cleaning? Followed by sentry duties? What about the ole in-out-in-out, man? Where in the hell are your priorities?

      Kinect seems to be one of those products that is really innovative. MS has put together technology that would be useful in many situations. So the question is why are they selling it as a toy and why are they selling it for only $150.

    • This is a somewhat different thing from what Johnny Lee did, though. Johnny took existing Wiimote driver code and used it to do some very cool things with the data, such as his famous head tracking demonstration. He didn't figure out the actual communications protocol, though (in fact, I did a lot of the early Wiimote reverse engineering hacks [] too; I guess I have a thing for wacky game controllers!).

      Unfortunately for us engineers and low-level hackers, the people actually finding practical algorithms and cool uses for these devices tend to get more attention than the people hacking the low-level details ;). I'm genuinely excited to see what computer vision experts can do with the raw Kinect data, though (I personally can't do much more than apply a cheap heat map to the data like I did in my video).
