Usability and handedness

Tuesday, September 29th, 2009

Recently, I read an article in the WSJ about people complaining that the Dvorak keyboard layout is not supported on most smartphones, whether they use physical keyboards like the Blackberry, or virtual keyboards like the iPhone.  There was one quote in particular that caught my eye – “The way he sees it, Dvorak users are like left-handed people and deserve the same kind of respect.”  That got me thinking about my experiences as a left-hander and how that makes my interactions with various products just a little bit different.

Being left-handed is more or less finding out that many different products just doesn’t quite work for you as intended.  In fact, in many cases products have been designed so that you are caused the most inconvenience possible.  I don’t begrudge people who tailor products to cater to right-handers – after all, it’s better to inconvenience just 10% of the population than to inconvenience 90% of the population – but at the same time it’s kind of frustrating.

Most of the time, the difficulty caused by being left-handed is just something silly. I remember the day I noticed that to put change into a vending machine, I basically had to stand all the way off to the right side of the machine in order to get my left hand into the proper location.  On the other hand, my right hand would’ve fit perfectly from just about anywhere.  Then there’s the teasing in art class because I could never use scissors correctly, and the way that I constantly smear hand-written notes when my hand brushes the paper.  But sometimes, the difficulty is much more than that.  The most powerful example is a chainsaw, which usually features a guard to protect the operator’s right hand.  The lack of a corresponding protection for the left side puts left-handers at a much greater risk of injury or death.  Overall, it’s a reminder to me to consider how different people might have different needs, and that sometimes, there is just no one magic solution that will please everyone.

The funny part of this whole thing?  My left-handedness means that I actually find QWERTY more useful than Dvorak in a way.  If my hands get tired, I sometimes switch to typing with just one hand, and naturally, it’s much easier with my left hand.  What I’ve noticed is that most of the important letters are clustered on the left side on QWERTY – to the extent that the New York Times once published a crossword puzzle where all the answers could be formed from letters on the left side of a QWERTY keyboard.  This would be impossible with the right hand.  On the other hand, the important consonants on Dvorak are clustered on the right side.  So maybe Dvorak users aren’t like left-handers after all…

How not to do usability: Blue Cross / Blue Shield

Thursday, September 24th, 2009

There are times when posting about a really bad user experience is simply an effort to amuse myself and my friends in usability, and so we can perform the all-important task of acting snotty and superior for a little while.  Then there are times when posting about a really bad user experience is to draw attention to something which truly has a terrible and awful effect on the human condition.  What I’m about to post is an example of the latter.

So I was calling up Blue Cross / Blue Shield to get pre-authorization for something, when in the middle of the phone tree, there was an option for “If this is a life-threatening emergency, press 1 now.”  This is all well and good – an insurance company’s goal is to keep you in good health no matter what the situation, even if it’s only so you can continue to pay your bills – expect for the fact that by the time I reached that option, I had already done the following:

  • Listened to several options on the phone that totally did not apply to me, including “Press pound if you are a provider or a non-member”, and “If you’re calling for some other program, the number has changed to this other phone number” – all spoken in a voice that was a tad on the slow side
  • Entered my birth date in month month, day day, year year year year format, with those instructions spoken out in detail, followed by the pound sign
  • Entered my eight-digit insurance identification number, which is on my insurance card that I had to dig out of my wallet, followed by the pound sign

All told, I reached this option after about two minutes on the phone.  I have to say that it felt rather long even calmly sitting in my office – can you imagine if it had really been a life-threatening emergency?  And having to wait for that long even after looking up the phone number for the insurance company and dialing it?

I also wonder what would happen if someone actually DID get to that option and select it My hope is that they would immediately be taken to an emergency operator, but I almost wouldn’t be surprised if it just sent you deeper into the phone tree.  Repeat after me: “If you have been shot, press 1.  If you are being digested by a bear, press 2.  If you are on a boat that is sinking, press 3.”

In short, a good general rule of thumb (and this applies for lots of things, not just UX!) is that if your behavior resembles a Monty Python sketchyou’re doing it wrong!

Nutsy Bolts: RELEASE!

Saturday, September 19th, 2009

For those of you who haven’t heard, Nutsy Bolts is LIVE!  (See my previous post explaining it.)  It’s an online multiplayer game that you can play right through your browser, without needing to use Flash or Java or anything!  Just go to the website and play!

Nutsy Bolts has been a long time coming for me – I started it even before I went to graduate school, and considering I’ve completely graduated since then, that should tell you something about how long I’ve been working on it.  I have a lot planned for it, but at the same time it’s great to get it out – both so other people can see it, and so I can work on something else for once (more details on that to come)!
