A newly developed driving interface may let blind people independently drive cars on the open road. Designed by engineers at Virginia Tech, the system incorporates various nonvisual cues into the driver’s seat of a dune buggy that could help the blind navigate roads without assistance.

Hands-on with Wii Classic Controller Pro: fingerprinty!
So we were sent a Wii Classic Controller Pro, the $20 update to the first-generation Classic Controller for the Nintendo Wii. Does it look more “pro” to you?
The controller is laid out very similarly to the first Classic Controller, with the exception of the fins coming down from the bottom of the controller. These fins are thinner than they look in pictures, and they take some getting used to. The idea here is to give the player a better grip than the SNES-style original, but in practice they never seemed to be positioned where we’d like them.

feature: How robots think: an introduction
A future full of helpful robots, quietly going about their business and assisting humans in thousands of small ways, is one of technology’s most long-deferred promises. Only recently have robots started to achieve the kind of sophistication and ubiquity that computing’s pioneers originally envisioned. The military has hundreds of UAVs blanketing the skies above Iraq and Afghanistan, and Roombas are vacuuming living rooms across the country. At the bleeding edge, there’s the DARPA Grand Challenge in 2005. This grueling, 140-mile, no-humans-allowed race through the desert showcased full-sized, completely autonomous robot cars that could navigate across rugged desert terrain, avoiding rocks and cliffs and cacti in a race for a $2 million cash prize. The follow-on 2007 Urban Challenge went even further, with the robotic competitors required to drive alongside humans on crowded roads, recognizing and avoiding other cars and following the rules of the road. Suddenly, the robotic future doesn’t look so far off.

Microsoft Asia prototypes fancy new inductive charging pad
Microsoft has applied for a neat patent for a smart inductive charger (via Being Manan). Inductive charging, used for example in the Palm Pre’s Touchstone, allows for contactless charging of devices in close proximity.
The charger couples inductive charging with an LCD screen that can be used to show off “weather conditions, sports scores, news headlines, and/or other selected items” through a wireless connection to a PC. More useful, I would think, would be some indication of the charging status of the device.

feature: The Ars Technica Guide to I/O Virtualization
Virtualization is a key enabling technology for the modern datacenter. Without virtualization, tricks like load balancing and multitenancy wouldn’t be available from datacenters that use commodity x86 hardware to supply the on-demand compute cycles and networked storage that powers the current generation of cloud-based web applications.

Nehalem Mac Pros take 20% performance hit when playing audio
Apple’s latest Mac Pro, jammed with multicore Nehalem-based Xeon processors, is designed to be a computing beast with power to spare for the most demanding tasks. Since the current Mac Pros became available in October of 2009, though, numerous users have reported a glitch, which appears to be related to audio processing, that causes those Xeons to run much hotter than expected. The problem also saps a surprising amount of performance as well.
