I found myself looking back at a 10-year-old rant about touch screens, or rather touch screens used where they weren’t the best solution: PIN entry pads for point-of-sale terminals.

We were at the grocery store earlier today, and Katie was grumbling about the stylus-only touch screens they had for entering a PIN. Unlike actual keypads, you can’t hide the number you’re entering, because you have to move that stylus around instead of 10-keying it in.

On one hand, a touch screen with a stylus is great for visual feedback and for collecting signatures, because the store can keep things on file digitally instead of or in addition to a paper copy. And once you’ve got that, it’s reasonable to drop the keypad, since you can simulate it in the touch screen. But unless it can react as quickly as actual buttons, and react to fingers instead of a stylus, it can’t completely replace the way a keypad is actually used.

What I find interesting about this is that the industry actually fixed the problem by rolling back: Even though touch-screen devices are all over the place now, I can’t remember the last time I used a touch-based POS terminal that didn’t have a physical keypad — often slightly shielded from view — for PIN entry. The occasional phone or iPad with a Square reader, but that’s it.

On the other hand, the Fry’s line notification system I griped about in the same article is still as lousy as ever.

Fifth generation iPodAs I moved our iTunes library last week, I worried that the new system might not be able to sync with the old iPod, but relaxed when I saw that Apple still sold the click-wheel iPod Classic. They discontinued it a few days later, but fortunately we were able to sync the old devices.

Why do I prefer the older iPods with physical buttons and tiny screens?

Because I listen to music in the car, and a touch screen is a terrible interface for quick actions while driving.

While touch screens are better for menus, searches, finding albums, playlists, artists, and just about anything else, they’re actually dangerous for driving. A physical control of some sort is best for any action you might have to take while behind the wheel of a moving car.

Pause/Play, Skip and Volume. Those are the key things you want to be able to do with music without thinking too much about where you’re reaching, or taking your eyes off the road. (Especially if you have a mix of quiet and loud songs.) Volume’s on the dashboard, but it’s so much easier — and safer — to hit an actual button for pause/play or skip than to jab at the touch screen until you get it right.

Randy Cassingham of This Is True has been driving a weekly Twitter event he calls Pet Peeve Wednesday, with the hashtag #PPW*. Some items I’ve posted about things that Just Bug Me(tm). I guess I shouldn’t be too surprised that they fall into two categories, tech and language.

Tech Annoyances

  • Mobile websites that change the URL so you can’t reshare the page on Twitter without sending desktop users to the mobile site. Or worse: the ones that redirect you from a full article to the front of their mobile site, so you have to hunt around for the article that someone was trying to share with you.
  • New password forms should always spell out the password policy before the user tries to pick something it doesn’t like.
  • If you have to cite a bogus law to claim that your email is not spam (or worse, that recipients can’t callit spam), it’s spam.

Language Annoyances

  • “Weary” means you’re tired of something, not concerned about it. You’re thinking of “wary” or maybe “leery.”
  • If you’re going to reference “Wherefore art thou Romeo?”, remember: she’s asking why, not where. (Think of it this way: The answer to “wherefore?” is “therefore,” and you know what “therefore” means.) It’s a lead-in to the “What’s in a name?” speech.
  • What do people think an “intensive purpose” is, anyway? The real phrase, “for all intents and purposes,” at least makes sense.
  • The word is “foolproof,” as in even a fool can’t mess it up, not “full proof.” (As opposed to what, half-proof?)

*There’s a hashtag collision with both “Pet Peeve Wednesday” and “Prove People Wrong” using the same tag.

Wow: A researcher studying the way people use computers found that most people don’t know how to search for a word on the current page!

Crazy: 90 Percent of People Don’t Know How to Use CTRL+F

Google’s resident search anthropologist, Dan Russell, dropped this incredible statistic on us. And no, he couldn’t believe it either.

To someone used to using computers, it seems so basic, but I guess if no one shows you it’s there, it’s the kind of thing that’s not easy to discover on your own. (via Slashdot)

The article doesn’t actually say which side of the 90/10 split people using toolbar buttons or menu items to search fall on, but it does mention people paging through an entire document to look for something by eye.
