IBM’s Supercomputer Has Implications for Healthcare, Information Tech and More

Wouldn’t it be nice to have your very own supercomputer in your pocket?

If your laptop crashed while you were working on a major presentation, you could ask your portable expert to help diagnose the problem. If you wanted to bone up on Middle Eastern history, you could ask it to comb every document available and then wrap it all up in a simple summary (annotated, of course).

Kinect Gestural UI: First Impressions

Read the manual before using the interface. (Kinect Adventures)
(Yes, it’s a *cute* manual, but these are still instructions to memorize.)

Summary: Inconsistent gestures, invisible commands, overlooked warnings, awkward dialog confirmations. But fun to play.

Kinect is a new video game system that is fully controlled by bodily movements. It’s vaguely similar to the Wii, but doesn’t use a controller (and doesn’t have the associated risk of banging up your living room if you lose your grip on the Wii wand during an aggressive tennis swing).

Why You Only Need to Test with 5 Users

Some people think that usability is very costly and complex and that user tests should be reserved for the rare web design project with a huge budget and a lavish time schedule. Not true. Elaborate usability tests are a waste of resources. The best results come from testing no more than 5 users and running as many small tests as you can afford.

In earlier research, Tom Landauer and I showed that the number of usability problems found in a usability test with n users is:

N(1-(1-L)n)

where N is the total number of usability problems in the design and L is the proportion of usability problems discovered while testing a single user. The typical value of L is 31%, averaged across a large number of projects we studied. Plotting the curve for L=31% gives the following result:

The most striking truth of the curve is that zero users give zero insights.

As a fan of football games, going back to the days of classics like Tecmo Bowl (NES), we were excited to play this year’s redesign of the successful Madden NFL series.

What’s Wrong With the RITE Method?

A critique of a common method used in video game usability research

Many video game usability practitioners employ a method to test usability within video games, called the ‘RITE’ method, short for Rapid Iterative Testing and Evaluation (RITE). Pioneered at Microsoft Games Studios and Microsoft Research, the RITE method has been adopted by many usability research organizations besides the teams at Microsoft.

While the RITE method has some advantages, such as the ‘rapid iterative’ ability to suggest changes to designers and test them in successive passes, it may fall short when looking for usability issues that lie beneath the surface.
