Project Natal

Project Natal was announced by Microsoft at E3 as new interface peripheral for the Xbox 360, which removes the need for a joypad, instead body movement, facial recognition and voice are used for interaction.

We have seen similar innovations with the EyeToy for the PS2 and the notion detection in the Wii, but both have severe limitations. The EyeToy is a single lens camera, so it is easily affected by lighting and background, while the motion detection in the Wii is built into the joypad and has limited capabilities by default.

The demo shown at E3 is jaw dropping, showing seemingly natural interaction with a character called Milo, but anyone with any experience of Microsoft demos treats them with appropriate levels of scepticism. Since they haven’t beaten the Turing test there is certainly some smoke and mirrors going on, in the words of Milo’s creator Peter Molyneux “If we had, then applying it to a computer game would be the last of the solutions we’d use it for.”


Other demos include a painting application and a dodgeball style game. They are relatively low tech examples but the dodgeball game has been demonstrated with journalists and celebrities, and has appeared to withstand their scrutiny. Interestingly Endgadget’s demo turned the lights down to see if it can cope with different lighting, and it had no problems.

Although shy on the details Microsoft have said it contains an RBG camera, an infrared camera, a multi-array microphone and a depth map. New Scientist among others suggested it is using the infrared camera technology by 3DV, an Israeli company that Microsoft purchased. This heat detection allows it to maintain a level of functionality regardless of light sources or obstacles.

Project Natal claims to have facial recognition and voice recognition, but we’ve only really seen this in the Milo demonstration, which could have been entirely scripted. So the extent of this capability is still not fully understood, although the voice recognition is based on Windows 7 functionality.

While Natal does recognise actions sitting down, a notable thing from the demos is the space of the room they were demoing in. When you use your whole body as a controller you need enough space to do so. A bit like Wii Fit, removing the traditional controller can pose logistical problems for the smaller household; for me my living room becomes more like an obstacle course.

Paradoxically playing a game with your body rather than your thumbs can be both more intuitive and harder work. I am old enough that can still remember my initial awkwardness interacting with a computer mouse or a console joypad, even though it seems like second nature now. However this hurdle is removed by Natal, making gaming and potentially all human-computer interaction much more accessible and intuitively responsive to an even wider audience, although it lacks the feedback a physical peripheral affords.

If I sat playing Burnout as it has been demonstrated with Natal my arms would ache after a while. But one thing I do know from marathon Guitar Hero sessions is that I will play through most aches for the right game. Interestingly a great many of the games we play allow us to explore far beyond our own physical limitations, so I wonder where the disparity is between simulation and escapism and what we desire from our gaming experience.

I don’t think we will be getting rid of the joystick anytime soon, but this definitely opens the door to new kinds of games and game play that we haven’t seen before. Its greatest potential is in the creative and imaginative hands of games and software designers everywhere.

Sharing media on your network with your Xbox 360

Ok I have had some real fun with getting my XBox to see my XP desktop. It was easy enough to get it to see my Vista laptop after I set up Windows Media Centre (WMC), and although WMC sees everything on my network it has no supports for DivX, so doesn’t really meet my needs.

However playing video through the XBox dashboard does have DivX support, but this way it only finds files that are local to my laptop and I wanted it to see my whole network. It wasn’t as straight forward as it should have been so here is my quick guide on how I managed to get it working. It’s not the only way, there are 3rd party tools out there.


Sharing media

Firstly you need to share the media from your XP machine. To do this you need Windows Media Player 11 (WMP11). WMP11 adds a bit of Vistas functionality into XP, so under Library>Media Sharing… click the checkbox and allow access to the XBox 360.

Problem 1
This didn’t work straight off for me, it just hung for ages and then nothing happened, no sharing and no error.

Solution 1
Check which services are running. Start>Admin tools>Services. You need to make sure UPnP and SSDP are both started and set to Manual, also check Windows Media Player Network Sharing Service is started and set to Automatic.

Problem 2
Once I’d done this I was able to share my media and allow my XBox. However my XBox still refused to see my XP machine on the network. So my PC could see the XBox but the XBox wasn’t seeing the PC. After a bit of reading around online and trying loads of stuff it became clear DRM was the issue. WMP11 DRM doesn’t work properly, it makes sense then that the XBox which is DRM’d up to it’s eyeballs would start having issues.

Solution 2
Clear out the existing DRM data. You need to set your Folder Views to include System files. Then navigate to Documents and Settings>All Users> DRM and delete all files.

Then go this link in Internet Explorer:

If ActiveX blocked you’ll need to allow it, once that’s done the greyed out Upgrade button should become clickable. Click it and what for the process to run then close the box. Reboot PC (definately) and XBox (possibly). After this the XBox detected the PC and media sharing was enabled.

All credit goes to @DocJelly and his amazing blog post for this solution.

Problem 3
This was a fairly simple problem to solve. The XBox doesn’t see folders that are shared on the networking the same way and WMC does, it only see the folders that are part of your shared WMP11 Library.

Solution 3
In WMP11 go to Library>Add to Library…

Add any folders with media that you want to share and click OK, it can take a while for your PC to catalogue the new folders and files.

Ongoing Issues
The Windows Media Player Network Sharing Service is a memory hog, so it may be worth disabling sharing if you aren’t using it frequently.

Even with WMP11 Library I’ve found it a little unpredictable about what the XBox will and won’t see. This might be because files are still being catalogued, so I’ll give it a bit longer before I investigate further.
