Technical Fields


I like that in TurboTax, they present "flags" and "notifications" that indicate something that user will need to come back to an look at. Good plan; if the field isn't critical at the moment, then the user can continue on with their process and return when they're ready to focus on the suggested task.

The problem I have in this example is the tech talk that is used: what is "service-1?" I have no context of what the issue is. I have to click on Fix in order to understand what the problem is so I can decide if I'm going to Flag or Fix it (of course, I've already clicked on Fix).

Better is to provide a more natural language of the field in question, or the title of the page.

Hiding things

In the Google account within the Contacts app on Android (more specifically, Motorola Droid Razr), you can select which contact groups you want to show on your phone. Fantastic, I said. Now I can only show those people who are truly relevant to me and ignore all the rest who, while important for historical purposes, clutter up my search when looking for a friend I want to call for lunch.

There are some problems with this. The one I am about to describe comes from an attempt to add a young lady's number into my phone.

I did. I entered it. Name, phone number, e-mail, even some notes. "Save," I pressed. And she was nowhere to be found. Did it again, just in case I hit "Cancel" (which, I did, btw, on this second attempt, forcing me to make a third attempt.

I went into GMail to compose a mail and when I began to type her name, voila!, her name came up. Twice, to be precise. She was obviously in contacts, but yet no form of search could find her.

It dawned on me. I had restricted my contact groups. I looked, and sure enough, when I turned on "My Contacts" (or was it "Other Contacts?" I don't know; I click lots of check marks), my lady friend's name showed up.

Moral of this story is, when designing a record system, provide a reasonable default that takes into account the user's current settings. I should have been able to at the very least select a default. Or perhaps better, Google should have auto-created (as it does with Starred Favorites) and "Added via Phone" group. That way, you know where your new contact came from.

The original Motorola Droid is not my favorite phone. I own it because I needed it for work and it was the first serious competition for the iPhone when it came out. Since then, many new phones have come out with wonderful features that I suspect could have been integrated into this particular generation of smartphone.

For me, the keyboard on the Droid is terrible. Most people complain about the lack of tactile feel, and I agree that it sucks, but that's hardly the sticking point for me.

Instead, the position of the Alt and Shift keys seemed flip. I find I use the keys about equally between capitalization and punctuation. However, it feels unnatural to me to have to stretch my thumbs out the the side to hit the shift key. Instead, I often hit the alt key instead when I need to capitalize a letter. And then I get frustrated and hit it again because I've inadvertently put a symbol in its place and then hit Del... erasing my entire line because I hit the Alt twice followed by the Del key. Not what I wanted.

I think the problem relates to the normal keyboard on a desktop. To hit the shift key, a person uses their pinkies, not their thumbs. However, on the Droid (or other mobile), you use your thumbs for all tapping; the other fingers are stabilizing the device, or as is the case of the pinkies, not being used at all. So if the usage model changes, so should the layout. Obviously, Motorola/Google didn't think this was a major problem and that people would probably get used to it. But what it really shows in a lack of thoughtfulness on their part. They have an extra blank space on each side of the keypad (where the red arrows are pointing); they could have extended the either the alt or shift keys to be larger and more accessible, for example, but only after having evaluated which set characters get used most often.

When messaging, I use a lot of contractions... it keeps the sentence structure proper (not using "u" and "ur" and things like that that) while keeping the character count down. So I need the apostrophe a lot. What a pain to type "I'll" as: Shift-I-Alt-M-L-L." The need to make a shift between the Shift and Alt keys makes the process very cumbersome. A larger keyboard with its own number row (or pad; does the ugly looking directional pad [green circle] ever get used? -- okay, sometimes, I guess) would have made life easier; put the key punctuation characters as shifted versions of the number keys instead. On top of that, you get the bonus of more easily being able to type numbers into a text field... you know, something that happens a lot on a TELEPHONE.

And don't get me into that overburdened space bar. The space bar simply should not have a double function. It should do one thing and one thing only, no matter what mode the rest of the keyboard is in. It drives me crazy to have shifted into alt mode while typing number and then have an odd dialog, unrelated to my need to have a space between numbers, popup when I hit the space bar.

There are some redundancies in the interface that I think could have been left out and made for better space. The Menu and Search keys are both duplicated on the 'hardwired' part of the touch screen (see in blue). In the case of the menu button in particular, if you select it, you get a task bar popup at the bottom of the screen. Meaning you have to move your finger to right around where the 'hardwired' touch button is anyway. So what's the point of a physical key? The search key makes a little more sense... but not in light of the fact that Moto could have used that space to make bigger Alt/Shift keys, or a better keyboard, or an "Fn" key for a third level of functions (if they really wanted to overload the modes on the keyboard!)

The take away here is actually deeper than my minor complaints about the keyboard. The fact is that Motorola is a very large company that, given the opportunity they had, blew it when it came to creating a useful and elegant design to compete with Apple's iPhone. The keyboard is simply under-designed. It's awkward and overloaded and uncomfortable to use. And there is little excuse for such a design failure when there were already tons of examples of keyboards out in the market (Blackberries galore!) to sample from, years of research to help, and tons of money invested into the project. This was simply a sloppy decision on Motorola's part.

A pop up calendar in the wrong place, but right time at least.


This is from a credit union site. It presents you with transactions for the current month and allows you to look back at the past history of transactions. However, when you click on the calendar icon, it opens another small window -- well away from where your mouse pointer is located. For me, this violates a couple of different design patterns:
  • Fitt's Law -- you're given a small target far away from the initial location.
  • Least Surprise -- it's a bit of shock to suddenly see another window open outside of the main window. What's it for? A spam ad?
There's a discordant association with the main window and the sub-window. What if you don't notice it? Then what?

A more viable solution would have been to connect the calendar icon with a menu drop, instead, that would let the user immediately understand the association between clicking on the icon and the results, as well as immediately knowing that clicking on the resulting small calendar would create the expected results. It would also prevent the user from having to move his or her mouse outside the scope of focus.
