• New way to guide a car: With your eyes, not hands

BERLIN — Tired of spinning that steering wheel? Try this: German researchers have developed a new technology that lets drivers steer cars using only their eyes.

Raul Rojas, an artificial intelligence researcher at , said Friday that the technology tracks a driver’s eye movement and, in turn, steers the car in whatever direction they’re looking.

Rojas and his team presented the technology-packed prototype under a clear blue sky at an airport in the German capital.

The Dodge Caravan crisscrossed the tarmac at the abandoned Tempelhof Airport, its driver using his line of sight to control the car. The car’s steering wheel was turning as if guided by ghostly hands.

The technology called eyeDriver lets the car drive up to 31 mph (50 kph).

"The next step will be to get it to drive 60 miles per hour," Rojas said.

Ultimately, however, the Mexican-born researcher is aiming for even more: "The biggest challenge is of course to drive in a city with pedestrians and lots of obstacles."

For now, exercises remain relatively simple. The Dodge chases a pedestrian or another car across the tarmac and shows his agility and even drives backward — the driver only has to look into the rear mirror to guide the car.

However, it remains unclear when — or if — the technology will be commercialized as questions about safety and practicability abound: What about looking at a cute girl next to the road for a few seconds? Not to mention taking phone calls or typing a text while driving.

But the researchers have an answer to distracted drivers: "The Spirit of Berlin" is also an autonomous car equipped with GPS navigation, scores of cameras, lasers and scanners that enable it to drive by itself.

"The car can do everything. It can drive autonomously or it can be guided by a driver’s eyes," Rojas said. The compromise is a mode that has the car driving on its own, basing its decisions on input from scanners and cameras, and only requires the driver to give guidance at crossroads.

"The car stops at intersections and asks the driver for guidance on which road to take," the researchers say. A few seconds of attention with the driver looking in his desired direction get the car flowing again.

To demonstrate the car’s autonomy, Rojas at one point jumped in front of the car — which was at that moment driving at perhaps 10 miles per hour — and the Dodge was immediately stopped by the cameras that had detected the obstacle.

"I was lucky this time," Rojas said jokingly.

• Xerox’s 1Q results lift stock as revenue climbs

NORWALK, Conn. — Xerox Corp.’s (NYSE: XRX) first-quarter results as well as its forecast for the current quarter topped Wall Street expectations Friday as revenue from services and copier and printer supplies picked up.

The company’s stock climbed 84 cents, or 8 percent, to $11.29 in morning trading after reaching a 52-week high of $11.72.

Xerox posted a loss of $42 million, or 4 cents per share, for the first three months of the year, compared with a profit of $42 million, or 5 cents per share, a year earlier. The company was dragged down in the most recent quarter by one-time expenses related to layoffs and its acquisition of Affiliated Computer Services Inc.

Excluding one-time costs, however, Xerox said it earned 18 cents per share, beating the average forecast from analysts of 13 cents per share, according to Thomson Reuters.

Revenue jumped 33 percent to $4.7 billion, primarily because of the ACS acquisition. On a pro-forma basis — assuming that the deal had gone through a year ago — revenue would be up 5 percent, Xerox said. Analysts expected $4.65 billion.

The increase in revenue came mainly from the addition of ACS’s business outsourcing segment, which takes on a variety of back-office functions for other companies.

Xerox was already doing some outsourcing, handling the flow of documents and printer systems for other companies. But the acquisition helped Xerox more than double its first-quarter services revenue. Assuming the deal had already gone through last year, services revenue was up 3 percent to $1.8 billion.

Sales of copier and printer supplies also picked up as corporate spending rebounded from the depths of the recession last year, climbing 15 percent on a pro-forma basis.

The company’s forecast for the quarter ending in June topped expectations. It expects earnings excluding one-time items of 20 cents to 22 cents per share. Analysts were looking for 18 cents, on average.

• Barnes & Noble e-reader to offer web browser

NEW YORK — Barnes & Noble plans to roll out a software update to its that will let users surf the Web and play games.

The bookseller said Friday the update will also allow users to browse complete books in Barnes & Noble stores for up to an hour a day at no cost, even if the book isn’t in the store.

Better Wi-Fi connectivity, faster page turns and better touch-screen navigation are also part of the upgrade.

Barnes & Noble’s Nook uses Google’s Android operating system. When it was launched, executives said Android applications could be developed for the Nook. The games, which includes chess and Sudoku, are the first Android applications.

Dedicated e-readers have been threatened by the launch of Apple’s iPad earlier this month. Amazon.com’s Kindle also offers a basic Web browser.

To offset attention on the iPad, Barnes & Noble launched an ad campaign Thursday touting the Nook, including the company’s first TV ads in a decade.

Barnes & Noble and other traditional booksellers have been pressured by tough competition from discounters and Web sites.

The New York company launched Nook as way to stake a claim in the electronic book space.

In February, the company said the launch of the Nook helped spur online sales, which rose 32 percent, but weakness at its bookstores led to a drop in profit during the third quarter.
