Lack of human factors = more of your tax dollars at “work”

April 22, 2012

I live in Raleigh, NC. Our area code has always been a little problematic for the nationwide 911 emergency system – it is 919. But at least until now, dialing the 919 for a local call was optional. Looks like we’re finally big enough for ten digit dialing and we can expect to pay the price in our public safety [...]

Older adults and Windows 8

March 13, 2012

In an earlier post we discussed how illuminating simple user testing can be. The video below is computer blogger Chris Pirrilo who put his dad in front of the new Windows 8 Preview. The dad seems to be relatively sophisticated and knows about Windows 7 but is completely flummoxed by Windows 8 new “Metro” interface. Note that this is the [...]

Here is a design that requires disobedience of the fundamental rule in a sport: don’t point your gun at someone you don’t plan to shoot. Blogger Mark Shead posits it might be due to a lack of domain knowlege by the designer and extends the analogy to software design. Mistakes in software design aren’t always as easy to spot, but often it [...]

The Touchy-Feely Future Of Technology Excerpts: “I wasn’t trying to make a computer interface, I was just trying to make a drum,” Buxton tells NPR’s Robert Siegel. “Did I envision what was going to happen today, that it would be in everybody’s pocket — in their smartphone?

Influence of Environment on Behavior

January 4, 2012

Two articles came up that both touched upon the topic of how behavior is shaped and influenced by the environment and how we shape our immediate environment to suit particular behaviors.  The topic of how behavior is constrained by the physical environment is a long discussed topic in psychology and human factors (e.g., affordances, ecological psychology, situated cognition, “cognition in [...]

Follow the link to read “A Brief Rant on the Future of Interaction Design” by Bret Victor. The briefest of summaries would be that we over-use simple touch in our visions of the future, when we could be including many other cues, such as weight and balance. From the post: If you’re with me so far, maybe I can nudge [...]

Don Norman Chimes in on Scrolling Direction

September 5, 2011

Touch Usability points to a nice Don Norman post about new gesture scrolling differences primarily instigated by Apple.  As a side note, i’ve fully converted to the “content moves” model (at home, work, laptop) and did not find the transition unusual at all.  As Norman notes, it just required a subtle mental shift in my model: Both models are correct in [...]

When poor usability costs you your job?

March 30, 2011

You may have heard that an employee who managed “social media” for Chrysler accidentally posted on Chrysler’s twitter account about *ahem* poor driving in Chrysler’s home city of Detroit. Click here for the original story. The guy who sent the tweet blames the program he used for multiple twitter accounts. The article calls it a “glitch,” which would not necessarily [...]

Honesty Hurts (especially when design is poor)

I enjoy the mix of economics and psychology, which is why I am a faithful reader of the Freakanomics blog. Their recent podcast on “pain” started off with a good human-factors-related tale of the problematic design of a subway alarm system. I have included a link below to the podcast, but the quick overview is that there is an ear [...]

The picture above shows the front and back of a trashcan designed to be lifted by machinery. This past weekend I helped my parents start to clear their home for an upcoming move and filled this trashcan to capacity. I didn’t want my mother to have to haul it to the street, so I went to go do that before [...]

Online Map Readability: A Comparison

December 3, 2010

Justin O’Beirne presents an extremely thorough and interesting analysis of why Google Maps appear more readable than its competitors. I’ve noticed this as well. It’s one of the major reasons I still prefer Google Maps despite some very compelling features of Bing and Yahoo maps. One visual trick that Google applies to maps is a localized de-cluttering around major cities. [...]

The picture above was taken from the Starbucks near the convention hotel for HFES 2010. Rich and I were walking in there at 6:30 a.m. when we saw a man exiting the doors, shaking them violently, and uttering curse words. We had to laugh when we saw what made him so angry – a push bar on the inside of [...]

Too standardized? – The problem of tube identification in hospitals

Thumbnail image for Too standardized? – The problem of tube identification in hospitals

When it comes to efficiency, creating standard sizes and connections saves money, production efforts, and makes for easy substitution when one runs out of an object. For example, I was delighted that lid for one brand of pot perfectly fit my new frying pan. Unfortunately, there are times when we do not want parts of one object to fit another [...]
