The EyeWriter is an open source eye tracking initiative. This is the mature version of the KanEye project we covered in April. Collaboratively developed by Free Art and Technology (FAT), OpenFrameworks, and the Graffiti Research Lab, they seek to aid a friend of theirs who suffers from the degenerative muscle disease ALS.

They’ve come a long way since we last looked in on the progress. The hardware used is pretty much the same: a set of sunglasses sans lenses with the CCD from a Sony PlayStation 3 Eye mounted in front of one eye. IR LEDs surround the CCD and point at the eye to increase the contrast between pupil and the rest of the eye. The major improvement comes with the software. Eye tracking appears to be extremely precise and they’ve written a custom drawing program to take advantage of their interface. Check in on their developer page for source code and a video walk-through of the software.

After the break you can see video of [Tempt1] using the system to create some tags. We’re thankful for the success this project has seen as this guy can do a lot better with his eye than we can with our hands.

[Max] was happy to see that the PlayStation 3 Eye has support in the newer Linux kernels. Having sat in his closet for quite some time, this would give the camera another chance at usefulness. Unfortunately, the driver doesn’t include framerate selection and color correction so he set about writing a patch to control the color settings. As you can see above, his success greatly improves the image quality you get from the device.

We get the feeling that the camera peripherals for Sony’s gaming devices seem like a good idea but don’t have much staying power as a realistic gaming interface. With contributions like [Max's], they can be re-purposed. The PS2 had its own, the EyeToy, which has long enjoyed driver support for Linux. The NUI Group does a lot of work with multi-touch and recommends the PS3 Eye for use with their projects because they’re inexpensive with high frame rates and decent picture quality.

Great work [Max]. It looks like he’s sent this patch upstream to be considered for incorporation into the kernel’s webcam module.

Gizmodo has done us all a favor by wading through many forum posts and condensing them into a handy guide to installing Ubuntu on your Playstation 3. It covers some of the caveats of going this route. You have to backup all of your game data before starting since the system repartitions the drive. Ubuntu installs without any problem, but because the cell processor is a PowerPC architecture it means not everything has been ported to it. There are a few things you need to install to get the Sixaxis controller to be recognized as a joystick. Super Nintendo emulator SNES9X is available and works, mostly. It doesn’t support fullscreen and cries if you reconfigure the buttons.

Supporting developers through alternate operating systems isn’t new to Sony. With the original Playstation, they released Net Yaroze, a consumer grade dev kit. The Playstation 2 was the first time they officially supported Linux on a game console (our first Linux machine). The ground breaking thing about the Playstation 3 was bundling in Linux support with every single console; no specialized hardware needed. Unfortunately they’re not near as open with the PSP.

A team of security researchers and academics has broken a core piece of internet technology. They made their work public at the 25th Chaos Communication Congress in Berlin today. The team was able to create a rogue certificate authority and use it to issue valid SSL certificates for any site they want. The user would have no indication that their HTTPS connection was being monitored/modified.

Here are a couple small programs to help you make the most of your Playstation 3 Sixaxis controllers. [netkas] heard that quite a few people were having trouble using the Sixaxis controller in Windows Vista. He solved it for himself and uploaded an exe for you to use. He then did essentially the same thing for OSX. This should make your PC gaming feel at least a little more familiar.

[Ben Heckendorn]’s Access Controller is now shipping. The controller is designed to be used with just one hand. It has six openings that the five control modules can be placed in. It’s easy to reconfigure depending on the player or game. While the prototype was built using Xbox 360 controller parts, this newly released unit is available for the PS2, PS3, and PCs. The Xbox 360 version is still being reviewed for final production. [Ben] says that in the coming weeks he’ll post a how-to for building your own modules. There’s always one empty slot and the bus like design should make this fairly simple.
