New Apple iPod shuffle: New commands in morse code!

Apple released the newest iPod shuffle today. It’s very small. The old version had a few buttons for navigation.

Now, the new iPod shuffle has no buttons. Instead, the headphones have the controls – Volume Up, Down, and a center button.

Two things wrong with this. One is not human factors, but nonetheless: you can’t use your own headphones with the iPod shuffle without buying some kind of adapter. Because the controls are on the headphones, you need to use those headphones.

Next, and more important to human factors, is how you control the thing. To play or pause, click the center button once. That’s not bad. But then… well, Apple has a whole table. Just read how complicated it is to perform some buttons. (Click the image to go to the source of the instructions)

To rewind, you TRIPLE-CLICK the center button? Supposedly, Macs only had one mouse button cause Steve Jobs thought people couldn’t tell right and left buttons apart. Now it’s triple-click. The sheer number of steps you need to memorize to operate this thing is nuts. Sure, you may say “I need to press three buttons to do the same thing on my regular iPod!” The regular iPod, however, has menus to serve as visual cues to tell you what you are doing. Here, you get a green or orange flashing light.

This is a bad idea. If nothing else, Apple should at least have redundant controls on the device itself – the same control scheme from the shuffle. Buttons for all the major functions. No double- or triple-clicking to be found. This is almost as bad as the MacBook Wheel.

Confusing manual terminology

This screenshot is from an instruction manual for an Audio/Video Receiver.

Obviously it’s a selected part of the manul, but it already has my head spinning. Specifically, I think the symbology they use for a button either on the main unit, the remote, or on both is tremendously confusing. Buttons on the main unit get a <> and buttons on the remote are []. The symbols don’t make intrinsic sense, and this little legend is published throughout the whole manual.

It’s somewhat difficult to think of some kind of replacement, though. Having no symbols (just bold letters) for buttons on both the main unit and remote makes sense. If a small but easily identifiable icon for “main unit” and “remote” could be created, those icons could be replaced next to the button names. It may take a bit of graphic design, but if the icons were good, the labeling would make far more sense.

The Whole Internet on your iPhone?

Apple likes to claim that the iPhone puts the whole Internet in your hand:

And, for the most part, it’s true. The question I’m considering here is: is that good?

There is so much screen space on a desktop or laptop that web pages are bigger, wider, and filled with graphical ads. When you try to shrink this down onto iPhone size, well… take this screenshot of the Washington Post:

The headlines are barely readable! Once you make them out, you can click on an article, and it’ll load it up. The whole page, including ads:

You can zoom in with a double-tap, at least, which makes the text bigger and more readable, thank goodness:

But there’s a lot of squinting and careful tapping to make sure you zoom in and not accidentally tap a link. Kind of a pain. OK, a real pain.

A lot of sites are still offering mobile versions – or, even worse, creating an iPhone-specific version that mirrors the main site. It’s not the whole Internet, but it’s way more usable. Here’s the mobile Washington Post site:

And then, when you click on an article? One-column, reasonably sized fonts, easy to read and scroll:

In my opinion, the mobile iPhone-specific Internet is far more usable than the Whole Internet that the iPhone gives you. It is good that the iPhone can render almost any page you navigate to, and it’ll be somewhat usable. But when the best usability experiences come from a limited version of a website designed specifically for your device, there’s a problem.

The solution, I would think, would be a larger screen. That would give the device more pixels to work with so text on web pages wouldn’t have to be so imperceptible. Of course, this makes the device bigger, less pocketable, and far less desirable. There are solutions, though: mini-projectors are here, folding and scrolling displays are not quite, and other technologies someone must be working on. Until then, we may be stuck with users hoping their favorite sites also develop limited versions of themselves, just for the iPhone.

GPS devices, automation, and creepy men with chainsaws

I have been totally reliant on my GPS since I got to Rhode Island, and it has been mostly reliable. There have been a couple of errors, but nothing too drastic. Coming back from nearby Whole Foods last night, however, nearly gave me a panic attack. The route given to me by my GPS took me through a dark industrial park, past dimly lit residential areas, a giant warehouse with big loading docks, and a construction zone with a recently leveled building.

Did the GPS get me home? Yes. Did it take the shortest route? Yes. Did I have no choice but to fully trust the automation and hope that I wouldn’t encounter creepy men with chainsaws? Yes.

Automation is a wonderful thing, but it is distressing to be at the mercy of a machine. Yet, in many ideal futures, our cars drive for us so we don’t have to do any work. Except worry about creepy man with chainsaws.

Thankfully, there has been a lot of research on automation in the human factors literature. Much of the research examines how humans trust automation and how automation use changes after a failure. One of the better review articles is:

Parasuraman, R. & Riley, V. (1997). Humans and Automation: Use, Misuse, Disuse, Abuse. Human Factors, 39(2), 230-253. (link)
