White iPhone 4 for T-Mobile caught in testing

Images of a white iPhone 4 test device with what looks to be support for T-Mobile USA's 3G bands have leaked, though whether that means the expected launch for the white variant this coming week will also mark its long-awaited debut on the network remains to be seen. BGR's sources sent them the shots, which show the white handset marked "confidential and proprietary" (just in case it's found in a bar) and with 3G support for T-Mobile's network.

Refreshed Mac Pro prototype is rack-friendly Xserve alternative?

Refreshed Mac Pro prototype is rack-friendly Xserve alternative?

Apple is reportedly considering a rack-mountable redesign for the Mac Pro, with one potential prototype already in circulation at the company's labs. According to 9 to 5 Mac's sources, the rackable, stackable Mac Pro is believed to be narrower and shallower than the current model - at just over 5-inches wide and 19-inches deep - with the thinking being that enterprise users could replace the discontinued Xserve with this new model.

The Engrain Keyboard is Made of Wood

The Engrain Keyboard is Made of Wood

I've spent a lot of time looking at strange keyboards. Anyone remember the miniguru? I even once spent a few hours browsing Cherry's website looking at the various high quality keyboard switches for an abortive project last year. That said, thank God for talented industrial designers like Michael Roopenian. Us computer users spend our time interacting with our machines primarily through the keyboard, it's the primary place where we touch and feel the physical presence of the machine. Usually we're rubbing our fingers all over a collection of cheap plastic keys. My current keyboard is an unimpressive slab of black plastic like I'm sure most of us are using. The Engrain keyboard is so pretty and I want one. Now.

Eye-controlled Head-Mounted-Display prototype shown by Fraunhofer IPMS

Eye-controlled Head-Mounted-Display prototype shown by Fraunhofer IPMS

We've been tracking the Fraunhofer IPMS' research into bi-directional OLED displays for a few years now: panels that integrated both a display and a camera, so that they can simultaneously track an object and display something. The institute has long promised that our head-up display (HUD) ambitions could well be satisfied with the technology, and now it has a prototype to show us. Set to make its debut at SID Display Week 2011 in May, the OLED microdisplay-based eye tracking HMD (head-mounted display) is, as the name suggests, capable of being controlled simply by eye movements.

Toshiba Resistive Multi-touch from Embedded World

Toshiba Resistive Multi-touch from Embedded World

By now we're all used to multi touch capacitive displays where the slightest brush of our fingers can zoom and pan the application. At Embedded World in Nuremburg, Toshiba showed off their prototype of a Resistive Multi-touch display using an ARM Cortex-M3 micro-controller. Most people don't have any problems with just using a capacitive screen, but in industrial and medical applications it's often necessary for the users to wear gloves, negating the benefit of capacitive screens. Resistive screens are also much less expensive than their same-sized capacitive counterparts, and are often more durable. Toshiba will have the ability to market this technology to touchscreen markets from ATM's to Point of Sale registers and beyond.

Samsung 55-inch glasses-free 3D HDTV could hit market in 3 years

Samsung 55-inch glasses-free 3D HDTV could hit market in 3 years

Samsung has demonstrated a 55-inch glasses-free 3D HDTV prototype which, the company claims, could be commercially ready in just three years time. Shown at FPD China 2011 this week, Tech-On reports, the display actually uses two LCD panels: one for the actual picture, and another, overlaid on top, the optical refraction index of which can be changed to flip between 2D and 3D modes.

64GB iPhone 4 prototype caught on video

64GB iPhone 4 prototype caught on video

A 64GB iPhone 4 prototype has apparently been spotted in Hong Kong, suggesting Apple is at least considering - or has considered - versions of the fourth-gen smartphone with greater capacity. Currently only 16GB and 32GB versions of the iPhone 4 are on sale; however, MIC Gadget found a grey market vendor who claims a "small quantity" of 64GB devices leaked from Foxconn's Shenzhen facility.
