Tobii Rex lets you control Windows 8 computers with your eyes

For those of you who have found the touch controls of the Windows 8 interface troublesome, Tobii has a new approach for navigating your computer. According to Engadget, Tobii is launching Rex, an eye-tracking camera that can be used to control a machine running the latest Microsoft OS.

The eye-tracking technology will work with the full range of Windows 8 computers, from tablets to hybrid laptops to desktops. About the size of a pen, the USB-connected camera attaches to the bottom of your monitor. Rex is meant to be used with a trackpad and mouse, so you won’t be able to toss those in the trash just yet. The mouse gives a greater degree of control over the clicking and selection, but your eyes do most of the broad navigational motions. The product is built on Tobii’s Gaze UI, which debuted similar features of eye control for a proprietary Windows 8 laptop last year.

The bar-shaped Rex bears more than a passing resemblance to Microsoft’s Kinect. The Kinect has been touted as a tool for the military and for doctors, but it seems unlikely that Microsoft hasn’t considered the potential to link up the motion sensor with its own computers. In fact, Surface general manager Panos Panay said during an “Ask Me Anything” on Reddit that Microsoft used Xbox 360 controllers with the Surface tablet, but had not tested out Kinect for that purpose. With the extra competition from Tobii to push Windows 8’s navigation into new territory, perhaps the Microsoft crew will be more interested in developing alternative approaches to controls.

Rex is currently only available as a special edition for developers at a price of $995 through the company’s website. Tobii said it anticipates making 5,000 consumer units available later this year. The price point for the consumer model will need to be significantly cheaper because, despite the serious coolness factor, the audience for a Windows 8-only device is pretty limited. It will be interesting to see if and when similar eye control setups appear for other computer models and operating systems.

Why you should sign up for PureVPN Max Plan

PureVPN is one of the best VPNs for these purposes, as it uses a global network of more than 6,500 servers that are located across dozens of countries.

Razer’s most boring product is also one of its best

The Razer Iskur V2 gaming chair in an office.

Razer isn't exactly known for subtlety. This is the company that released a Bane-like RGB face mask, a headset with haptic feedback, and most recently, a mouse pad that has RGB lighting from corner to corner. The Iskur V2 chair is an exercise in subtlety, however, and a change of pace that pays off for Razer in a big way.

There's nothing special about the Iskur V2 at first glance. It's a gaming chair fit with the usual racer-style back and some green trim to let you know it's a Razer product. But there are no motors promising immersive haptic feedback, and no RGB leaving you tethered to a wall outlet (yes, Razer has done both in a chair before). The Iskur V2 is just a well-designed, comfortable chair, and that's exactly why it's so impressive.
