Mobile UX Sharpens Usability Guidelines

Summary: Many guidelines are similar for mobile and desktop design, but their mobile interpretation is much more unforgiving.

My recent column Mobile Content: If in Doubt, Leave It Out advised site owners to eliminate secondary material when writing for mobile users. Many tweets, blog postings, and other comments on the article all expanded on this theme: Yes, do cut the fluff from mobile content, but also cut secondary content when writing for desktop websites.

In one way, I can only agree. Since 1997, conciseness has been a key guideline when writing for the web. People don’t read a lot on the web and leave in a few seconds if a site doesn’t communicate its value clearly. These findings lead to more detailed guidelines, such as emphasizing the first 2 words of nanocontent (e.g., headlines and search engine links).

So yes, cut the blah-blah from your desktop site.

The Future of Gaming: A Portrait of the New Gamers

In the spring of 2011, Latitude Research launched a study to understand the recent explosion in gaming, driven in part by the popularity of mobile phones and tablets. Specifically, the study sought to uncover how the profile of the stereotypical gamer has changed, various motivations for gaming, and the evolving role of games in moving traditionally online experiences into the “offline” world—suggesting new opportunities for game and technology developers, educators, and social innovators.

Sony Says Games Will Read Emotions in 10 Years

Sony is talking crazy, indicating that games may be able to tell if you’re lying or depressed just ten years down the road. We’ll stick with growing crops, thanks.

Seriously, when do games stop being games and cross over into virtual reality? This was the question I asked Nvidia months ago at ECGC 2011, and was told there will always be a market for the high-end PC gamer with the rig nearly the size of a bookcase. But putting visual realism aside, what will happen when games suddenly stop acting like games, and become more like a self-aware super AI that could possibly one day sing you happy birthday or annihilate the human race?

For IBM’s Watson technology, What Happens After “Jeopardy!”?

 

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).

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.

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.

GDC: Sid Meier’s Lessons On Gamer Psychology

Sid Meier is known as the mastermind behind some of the most respected and influential video games of all time, such as Civilization, Railroad Tycoon and Pirates.

But in his pursuit of conveying a realistic experience for players, he says his logical mind wasn’t taking into account enough what was going on in players’ heads.

“Gameplay is a psychological experience,” Meier acknowledged during his GDC keynote. Today he is director of creative development at Firaxis Games. “By acknowledging that gameplay is actually a psychological experience we … can end up with a better game.”

Meier outlined specific psychological elements that occur in players’ minds, such as “The Winner Paradox.” Game designers are supposed to give gamers a challenge, but the gamer at the same time expects to win. “In the real world you don’t always win, however in the world of games, you always win” in some capacity, Meier said.
