The Face of the $100 Laptop

Usability testing needed for $100 laptop user interface design ...

"The so-called $100 laptop that's being designed for school children in developing nations is known for its bright green and white plastic shell, its power-generating hand crank, and for Nicholas Negroponte, the technology futurist who dreamed it up and who tirelessly promotes it everywhere from Bangkok to Brasilia. What has not received much attention is the graphical user interface—the software that will be the face of the machine for the millions of children who will own it. In fact, the user interface, called Sugar, may turn out to be one of the more innovative aspects of a project that has already made breakthroughs in mesh networking and battery charging since Negroponte unveiled the concept two years ago.

... Child-centric
It's the first complete rethinking of the computer user interface in more than 30 years. "We're building something that's right for the audience," says Chris Blizzard, the engineering project leader for Sugar. "We don't just take what's already there and say it's good enough. You can do better."

The audience he and his colleagues have in mind is the hundreds of millions of poor kids all over the world. Negroponte came up with the nonprofit "one laptop per child" idea when he was chairman of the MIT Media Lab and observed the failure of standard attempts to use computers in education to improve the lives of underprivileged children. Typically, a handful of computers, designed for business applications, are installed in schools; students only use them in special computer classes and are forced to share. Negroponte's idea was to give a laptop to each student that he or she could take to every class and bring home at the end of the day. "OLPC is child-centric, designed to be a seamless part of their lives at home, at school, and in play," he says.

... While XO has been greeted warmly by many, some technologists criticize Negroponte and his colleagues for not testing out their new ideas on underprivileged school children earlier in the process. And that goes for the user interface as well. Jakob Nielsen, a user interface designer and principal in the consulting firm Nielsen Norman Group, falls into the critical group. While familiar with the design of Sugar, Nielsen’s criticisms focus on the process. It’s only in the coming weeks that they’ll begin to get feedback from kids. “It’s always dangerous to release any product without the safeguard of user testing,” says Nielsen. “But it’s outright reckless in a case like this.”

But XO developers defend their approach, which grew out of a core philosophy of the MIT Media Lab known as "demo or die." Researchers are encouraged to build new things, critique them, and then make improvements—rather than doing a lot of concept-testing up front. They're backed up by John Maeda, a user-interface design guru from the Media Lab who has been watching the XO development process from its beginnings. "They're using the Steve Jobs method," he says, referring to Apple's famous chief executive and design whiz. "You don't use focus groups. You just do it right."    (Continued via Business Week)    [Usability Resources]

What? I'm under the impression that Apple has always relied on user testing of their designs going back at least as far as the Lisa.
