Sometimes it’s good to take a step back from the seriousness of our work and find new focus. H(aiku)man factors is the brainchild of my colleague Douglas Gillan. Each summarizes a concept in the field while following the haiku form of 5-7-5 and an emphasis on juxtoposition and inclusion of nature. Enjoy and contribute your own in the comments!

I was reading articles the other day and came across a site that, as many do, reformatted for my phone. Almost all reformatted-for-mobile sites are terrible, but this one is my favorite.
You cannot scroll through the 21 page article by moving your finger up and down, as would happen on a website. The only way to change pages is via the horizontal slider at the bottom. Good luck trying to move it so slightly it only goes forward one page! And yes, moving the slider left and right does move the page up and down.
For those who don’t follow news of climbing accidents as closely as I do, there has been a spate of accidents associated with the automatic belay devices (autobelays) installed at climbing gyms.
These devices are handy to have around as they negate the need for a climbing partner, allowing one to exercise and train alone. The climber clips his or her harness into the device at the bottom of the wall, and it automatically retracts (like a seat belt) when you climb upward. At the top, you let go of the wall and the device lowers you slowly back to the ground. You are probably imagining that the accidents had to do with failures of the equipment – while that is not unheard of, the most recent issues have all been with climbers forgetting to clip into the system at all.
The most recent tragedy occurred this past September, where an experienced climber died after a fall in a Texas gym, and it’s been listed as so common it happens at “every gym,” though not always resulting in a fall. Here is the facebook page with members of another gym discussing a similar accident.
If you talk with climbers or read accident forums you will invariably be faced with a large contingent bent on blaming the victim. I’ll grant that it is hard to imagine forgetting to clip into a safety device and climb 30 feet up a wall, but that’s because I hardly ever do it. One characteristics these accidents share is that the victims were experienced and used the auto-belays frequently.
When a procedure becomes automatic, it becomes more accurate and less effortful, but it also becomes less accessible to the conscious mind. When a step is skipped, but all other steps are unaffected, it’s especially hard to notice the skipped step in an automatic process. If caring more or working harder or “being more careful” could actually prevent this type of problem, we wouldn’t have any toddlers left in hot cars, perfectly good airplanes flown into the ground, or climbers falling because they didn’t clip into the autobelay.
That brings me to the device I saw installed at a climbing gym last night.
Above: The guard in place, clipped to the wall and ready to go. Notice how it blocks the footholds of the climbs.
Above: Nikki shows how to unclip the guard before attaching to her harness.
Above: Clipped in and safely ready to go. Guard is on the ground and out of the way (it is ok to step on it!)
Using it properly does not add any additional time or mess to climbing a route. If it weren’t there, the climber would still have to unclip the autobelay from an anchor close to the ground, etc. With it there, the climber does the same thing and once done, the guard becomes a flat mat that doesn’t get in anyone’s way.
Is it perfect? No. You can also climb with a belayer on the same or nearby routes, and then it’s also blocking your way at the start of the climb. Some adaptation should be made by the route-setters at the gyms to minimize this. But overall, what a great and simple solution.
This clip of Fox News’ new studio has been tearing up the internet. But what caught my eye was the touchscreen lag and general unresponsiveness/accidental touches of the users in the background (see image at top; video here). Starting at the 10 second mark, note the user on the right.
Kim Wolfinbarger sends along a new case of dangerous things being confused for food (the story is the same but the actors different, see previousexamples). Before you reflexively say, “only an idiot would confuse the two,” remember that 5-year olds don’t know the difference. First rule of HF-club: you are not the user (or victim):
In California alone, 307 cases of accidentally ingestion of laundry packs by young children have been reported this year. And the cases in California, and nationwide, aren’t just limited to toddlers snarfing Tide Pods. When the product was released, Tide rivals such as All and Purex launched their own single-dose detergent capsules as well. Earlier this summer, Tide reconfigured the packaging of the product, adding a double-latched lid to the plastic tubs containing the Pods to make it more difficult for children to tamper with. Still, the number of reported incidents continues to climb along with news stories warning parents to take caution.
Just yesterday, Consumer Reports reported on a wave of Tide Pod-related poisonings in Glasgow, Scotland while the New York Daily News published a quick article stating that in New York City alone, 40 children have been hospitalized after eating the packs since April. TODAY also just published a piece on the alarming trend in which Ken Wahl, medical director for the Illinois Poison Center states: “I’ve never seen a consumer product that had that degree of injury in a child.”
Dishwashing detergent also comes in pod-like single serving doses but I am not aware of similar cases of ingestion. Maybe it’s the coloring (they tend to be blue/green) or size (they are a bit larger I think)?
This humorous NYT article discusses the foibles of auto-correct on computers and phones. Auto-correct, a more advanced type of the old spell checker, is a type of automation. We’ve discussed automation many times on this blog.
But auto-correct is unique in that it’s probably one of the most frequent touchpoints between humans and automation.
The article nicely covers, in lay language, many of the concepts of automation:
Out of the loop syndrome:
Who’s the boss of our fingers? Cyberspace is awash with outrage. Even if hardly anyone knows exactly how it works or where it is, Autocorrect is felt to be haunting our cellphones or watching from the cloud.
We are collectively peeved. People blast Autocorrect for mangling their intentions. And they blast Autocorrect for failing to un-mangle them.
I try to type “geocentric” and discover that I have typed “egocentric”; is Autocorrect making a sort of cosmic joke? I want to address my tweeps (a made-up word, admittedly, but that’s what people do). No: I get “twerps.” Some pairings seem far apart in the lexicographical space. “Cuticles” becomes “citified.” “Catalogues” turns to “fatalities” and “Iditarod” to “radiator.” What is the logic?
One more thing to worry about: the better Autocorrect gets, the more we will come to rely on it. It’s happening already. People who yesterday unlearned arithmetic will soon forget how to spell. One by one we are outsourcing our mental functions to the global prosthetic brain.
Humorously, even anthropomorphism of automation (attributing human-like characteristics to it, even unintentially)! (my research area):
Peter Sagal, the host of NPR’s “Wait Wait … Don’t Tell Me!” complains via Twitter: “Autocorrect changed ‘Fritos’ to ‘frites.’ Autocorrect is effete. Pass it on.”
