If we count all the screens in our lives, it takes a hot minute. Some of them are touchscreens, some need a mouse or keyboard, but we are accustomed to all the input devices. Not everyone can use the various methods, like cerebral palsy patients who rely on eye-tracking hardware. Traditionally, that only works on the connected computer, so switching from a chair-mounted screen to a tablet on the desk is not an option. To give folks the ability to control different computers effortlessly [Zack Freedman] is developing a head-mounted eye-tracker that is not tied to one computer. In a way, this is like a KVM switch, but way more futuristic. [Tony Stark] would be proud.
An infrared detector on the headset identifies compatible screens in line of sight and synchs up with its associated HID dongle. A headset-mounted color camera tracks the head position in relation to the screen while an IR camera scans the eye to calculate where the user is focusing. All the technology here is proven, but this new recipe could be a game-changer to anyone who has trouble with the traditional keyboard, mouse, and touchscreen. Maybe QR codes could assist the screen identification and orientation like how a Wii remote and sensor bar work together.
Sony is rolling out a firmware update for the PS3 on April 1 but we’re pretty sure it’s not a joke. What we’re not sure about is that you can call it an update. It removes features rather than fixing or adding them. In this case, it is removing the “Install Other OS” option that allows you to run Linux on non-slim versions of the PlayStation 3. It is fairly obvious that this is a reaction to the hypervisor exploit that was released back in January that breaks down the machine’s security barriers.
[Geohot], the guy who found and release the exploit, published a post on his blog expressing his disapproval of Sony’s actions. We’d have to agree. It’s pretty cold-hearted to remove functionality that was advertised with a product. We’re sure there are many folks out there using the Linux support who have no interest in exploiting the product. This is gardening with a backhoe and quite frankly it stinks.
This may bring on a torrent of new effort in unlocking and laying bare the PS3. If so, doesn’t Sony deserve it?

There is very little information out at the moment, but [geohot] has successfully hacked the PS3 to have full read and write access, bypassing the Hypervisor. At the moment he’s not revealing the exploit, but with this knowledge it wont be long before the PS3 finally gets whats coming. Keep track of [geohot’s] progress on his twitter, @geohot, and blog.
