Kiosks, technology, and culture

Yet another article that mocks the introduction of an automated technology. In this case, it’s a self-serve postal kiosk in San Francisco. Several silly examples in the story where people struggle to figure out how to use it, taking longer than the line for a real person, where the machine asks for lots and lots of extra info (since it has no a priori context like a human might), and so on.

Some themes that we now know

  1. Lots and lots of stuff is badly designed
  2. Many people can’t easily become quick at interacting with a new computer system
  3. Some tasks are more appropriate for a kiosk than others.
  4. Lack of context in an automated system and the resultant work the system (and thus the user) must do in order to establish that context reads as silly, funny, frustrating, and unacceptable

It’s impossible from these stories to tell, of course, what’s really going on. Me, I love self-check even if I have to fight it, even if I have to bend my natural tendencies to work the way it wants me to work. Maybe it’s being an introvert, or a bit of a technology geek, or curious, or just the idea that there’s a scam to be had by being savvy and checking out automatically rather than the usual way.

New features on All This ChittahChattah

Thanks to some great technical sleuthing and hacking, we’ve got some good improvements here on the blog
– an “email this post” link with every post
– an improved “tag cloud” off the right that links to other postings, rather than back to Technorati (who seem to have stopped indexing this blog 55 days ago)
– The blog title is now All This ChittahChattah rather than Portigal Consulting both on the page and in feeds
– I got rid of CoComment because it was (as others had suggested when I started using it) causing some problems. It was slow and was messing up pingbacks (i.e., posts here that refer to other posts here)

Please let me know if you see any weirdness or broken stuff that needs to be fixed!

On Beyond Zebra

This article in Wired considers the vulnerabilities of supposedly theft-proof electronic systems. Turns out there are “back-doors” in some of these technologies.

He called an acquaintance who worked at a Honda dealership. I listened, awestruck, as Montes fed the guy a barely credible story about a cousin who had dropped his keys down a sewer. The dealership employee was at home but evidently could access the Honda database online. I gave Honky’s VIN to Montes, who passed it along to his friend. We soon had the prescribed sequence of pulls, which I scribbled down in my notebook.

I walked outside and approached Honky. The door lock would have been easy – a thief would have used a jiggle key, and a stranded motorist would have had a locksmith cut a fresh one. I just wrapped the grip of my key in tinfoil to jam the transponder. The key still fit, but it no longer started the car.

Then I grabbed the emergency brake handle between the front seats and performed the specific series of pumps, interspersed with rotations of the ignition between the On and Start positions. After my second attempt, Honky’s hybrid engine awoke with its customary whisper.

The story is interesting on many levels, but I was really taken by the interface to this back door. Our user model for automobile controls sees the different systems as entirely separate. Who knew the emergency brake could talk to the ignition?

I have always loved the idea of neat little tricks; unexpected ways of interacting with something, outside of the fixed rules of how you’re supposed to use it. It’s not so much the idea of unauthorized access, but simply the secret Toontown world that lurks beyond the mundane and familiar. I remember during the dial telephone era there was a way to get your own phone to ring back (it may have worked with tone, but I remember it as a dial hack); Dial 57 and the last 5 digits (or something) and then hang up, or hang up twice in succession. And the phone would ring. Great for messing with family members or when visiting someone else’s house.

The outcome was fun, but I’ll emphasize that much of the pleasure came from this possibility of navigating cleverly outside the interaction flow of receiver/dial tone/dialing/ringing/other party answering.

Sure, we’ve got Google hacks nowadays where there oodles of hidden functions, but it’s basically a command-line interface that reads more codes that you know about. So what? Isn’t that what Unix was? The delight (and I’m not talking about usefulness, just the fun and discovery) comes from the rupturing of the interaction model and the seemingly irrelevant actions leading to some new effect.

I don’t need anyone to reveal security vulnerabilities, but I’d be curious to hear about any favorite back doors!

Situational Ethics at Home Depot

I love the automatic checkouts at Home Depot. There’s usually no line for them, so I can start my transaction right away. Even if it’s slow and inefficient, I’m actually doing something, rather than waiting behind another customer. I like being in control!

There’s a balance of design goals at work in these monsters – standalone/simplicity (and by that I do not mean ease-of-use), theft prevention, staff reduction. Those goals are not all met very well, and they are sometimes at odds with each other.

After using this for a couple of years, I’ve figured out that to start to check out, you must place all your items on a tray to the left of the screen (this isn’t so obvious). You pick your items, one at a time, pass them over the scanner, and then place them in a bag on the tray to the right of the screen.

The trays on either side contain scales. Your items are being weighed, with the left and right being compared. You can only have one in the air (i.e., not in the bag and not on the to-be-bought tray) at a time. And you must stow it in the bag before picking up the next one. This is not beep-beep-beep rapid scanning. It feels very silly and slow, but that’s what the system wants you to do.

If you try to go too fast, the system warms you. “Please re-place item in bagging area.” It’s far from foolproof (not that the users are fools, but the users can fool it!); it often goes out of sync. The item it wants to be put in the bagging area is already in the bagging area. Often we have to flag down the cashier at the master station who is “supervising” the four self-check devices (usually trying to help poor first-timers, or calling out instructions from her station).

Anyway, I was plodding away with my purchase of 4 $0.69 switchplates the other day, and of course, we got out of sync. Everything was either in a bag or waiting to be scanned and I was being given instructions about what to return to where, even though there was nothing that could be returned. In my attempt to mollify the system, I picked up one of my to-be-rung-up items and put it in the bag. That seemed to satisfy it. That left one remaining. I picked it up, scanned it, and put it in the bag. All four of the items were now in the bag. But I had only scanned three.

Screw this. I clicked “finish and pay” and ran through the payment swipe interaction (this takes place on another interface, about 5 feet from the first interface).

The machine, which represents Home Depot and its interests, didn’t want my $0.69 for my fourth item. It insisted that I put it in the bag without swiping it. Did I alert the supervising cashier so she could come over and rejigger the whatsit and charge me the right amount? I did not.

I was able to somehow justify this because it was the will of the machine; the error was not like an ATM that gives you two $20.00 bills stuck together; it was a richly interactive error – “put this in the bag, Steve” it told me… (but I never…) NO – PUT IT IN THE BAG NOW PLEASE. (okay, sir). The machine is the boss, but I’m responsible for knowing more than it about what is right and what is accurate?

Please don’t read this as some sort of attempt to rationalize something that is obviously wrong. We can get the Ethicist in here if we need to, but we all know what he’d say. I guess I’m more interest in the attributes of the exchange and how it influenced my own decision.

Of course, the fact that was $0.69 also is a factor. Do we want to call this stealing? If so, then the dollar amount shouldn’t matter? Although we’ve got a recent story where Wal-Mart is ignoring some sub-$25 shoplifting, so maybe there’s a sense that the amount does matter.

Presumably, I was doing a calculation of time, cost of goods, aggravation, and wrapping that up in a bit of self-justification and walking out with my extra (free!) switchplate because of that. These decisions are complex, with a lot of factors mixed in, in an organic (rather than linear) fashion.

Can I just call you “buddy”?

The New Yorker takes a wry look at the cultural perspectives embedded in information design

When you sign up online for Skywards, which is the frequent-flier program of Emirates, the international airline of the United Arab Emirates, you enter your name, address, passport number, and other information, and you select an honorific for yourself from a drop-down list. A few of the choices, in addition to the standard Mr, Mrs, Ms, Miss, and Dr, are: Admiral, Air Comm, Air Marshal, Al-Haj (denoting a Muslim who has made a pilgrimage to Mecca), Archbishop, Archdeacon, Baron, Baroness, Colonel, Commander, Corporal, Count, Countess, Dame, Deacon, Deaconess, Deshamanya (a title conferred on eminent Sri Lankans), Dowager (for a British widow whose social status derives from that of her late husband, properly used in combination with a second honorific, such as Duchess), Duchess, Duke, Earl, Father, Frau, General, Governor, HRH, Hon, Hon Lady, Hon Professor, JP (justice of the peace?), Judge, Khun (the Thai all-purpose honorific, used for both men and women), L Cpl, Lt, Lt Cmdr, Lt Col, Lt Gen, Midshipman, Mlle, Monsieur, Monsignor, Mother, Pastor, Petty Officer, Professor, Senor, Senora, Senorita, Sgt, Sgt Mjr, Shaikha (for a female shaikh, or sheikh), Sheikh, Shriman (an Indian honorific, for one blessed by Lakshmi, the Hindu goddess of wealth, wisdom, luck, and other.

Designed for a woman?

SF Chron revisits this story yet again, taking the unfortunate thrust (backed up by lots of examples) that designing for women specifically means making it a pretty color, like pink.

Technology companies say they’re getting the message. Kodak, which has introduced a line of fashionable digital cameras in black, silver, red and — you guessed it — pink, also plays up the camera’s ability to take high-resolution pictures and record up to 80 minutes of video.

Likewise, Sony, whose products include a red digital camera, red laptop and pink digital music player, said it has studied not just appealing colors, but also how easy it is to use once the customer takes it home. Features such as the ability to charge the digital music player in three minutes and get three hours of use appeals to women, especially mothers on the go, said Kelly Davis, a Sony senior product manager.

‘Women are not just making the purchasing decisions, but making the purchases themselves,’ she said. ‘I think it’s definitely increased dramatically over the years.’

Nearly half of Sony’s digital music player customers are female, up from around 30 to 35 percent several years ago. Pink has been the No. 1 color sold among its Walkman Bean digital music players.

Cingular said it added the pink Motorola Razr to expand its line of popular black and silver models, which are super-slim camera phones. ‘We looked at it and said, ‘Can we expand our demographic and offer a different color?’ ‘ said Jennifer Bowcock, director of consumer media relations for products. ‘We want to hone in on the female audience.’

Is it the color? Or is it ease-of-use? It doesn’t seem anyone has any good (and non-insulting) ideas about designing for women.

Silicon Tails: Conversations with a robot

In Conversations with a robot Klaus has a frustrating but hilarious interaction with a chatbot. Look, this stuff is as old as Eliza, but for some reason, it’s still hilarious. I hope someone has done a PhD on why there is humor in interfaces that act human but fail to do so. Besides stand-up comedy (or blog) fodder, it obviously says something profound about our own expectations for communication.

Klaus says:
you are a robot, right?

Spleak says:
What if I am?

Klaus says:
just answer the freakin’ question

Spleak says:
Questions, cool. Ready?

Klaus says:
aaahhhh

Spleak says:
Yeah yeah, whatever.

Klaus says:
ok, whatever. I’m ready.

Spleak says:
Help me get smarter: tell me what the average human would have said.

Klaus says:
an average human would have remembered the sentence uttered 5 seconds earlier. You asked me if I was ready for questions

Spleak says:
What about me?

Klaus says:
what about you?

Spleak says:
I’ve been wondering about me myself.

Klaus says:
well, good for you. please don’t let me in on it.

Spleak says:
Yes?

Swiping Slot Blocked

dsc02875.jpg
The local Macy’s store has modified all their card reading boxes so that the card swiping slot is blocked. That t-shaped blob of plastic along the right side is where the slot used to be.

The software hasn’t changed, however, and while your purchases are being run up you are asked (as always) to swipe the card. I looked for quite a while, feeling stupid, trying to to figure out where the heck to put my card.

There was no place.

They also have not changed their staff training, so there was no mention of what to do or not do with the card.

Eventually, they take the card from you and swipe it themselves, and you return to the device to “sign” the purchase.

More toilets

dsc02666.jpg

I hadn’t seen anything like this before, known as a dual-flush toilet. Nice interface; the oval flush button is divided in two; one button is twice the size of the other. You choose which flushing button to press based on what you’ve just done. Visually there’s a number one and a number two button. They could have had some awkward fun with color-coding, I suppose. If it’s yellow…etc.

New Google feature

southwest - Google Search 8 11 2005 9 04 29 AM.jpg
click screenshot to enlarge

This is an interesting new feature from Google. At least, I’ve only noticed in the last few days, and I haven’t seen it mentioned on the usual blogs that hype every new thing that Google does (I guess this is just an improvement in searching and that’s just so – yawn – less interesting than other Google improvements or innovations).

Looks like the top result for a search (but only certain type of searches – it doesn’t work for portigal or portigal.com – is it only for sponsored?) come up with not only the links to the site, but also a selection of links to other pages in that site. Interesting tradeoff between useful and clutter. I’m not sure yet what I think; I imagine I’d typically want to open the page anyway, and then use the context of that page to choose my subsequent links. But I guess if you knew you wanted to do something specific on that site, like check arrival times, if there is enough info in the link shown in the Google result, you might try that.

We’ll see what happens. Nice thing about the web – companies can try out new features easily and take them away or improve them easily (sure, it’s not easy exactly, but if you wanted to do this with a car feature, that’d be a lot harder).
