Quick thoughts on Twitter's UX

I liked this passage on some of the psychological differences between the UX of Twitter and Facebook, particularly the concept of following as a subscription and the type of relationship that sets up vs. friending. Given the privacy debacle Facebook has been dealing with the past 36 hours, the note on the simplicity of the privacy is also a big plus for Twitter.
 
Twitter nailed a few important things in their user experience compared to alternatives like Facebook. Posts are public by default, so there aren’t debates or surprises about privacy. Streams are built out of subscriptions (“following”), not “friendship”—a word that loses meaning when your friends are 500 strangers.

Repetitive, bored and urgent

The NYC Usability Professionals Association recently, held the "Google Presents User Experience & Mobile Apps where Google UX designer Leland Rechis described the three user states Google uses to characterize mobile device users:
  1. Repetitive - Users who are checking for the same piece of information over and over again, like checking the same stock quotes or weather. Google uses cookies to help cater to mobile users who check and recheck the same data points
  2. Bored - Users who have time on their hands. People on trains or waiting in airports or sitting in cafes. Mobile users in this behavior group look a lot more like casual Web surfers, but mobile phones don't offer the robust user input of a desktop, so the applications have to be tailored.
  3. Urgent - Users who have to find something specific fast, like the location of a bakery or directions to the airport. Since a lot of these questions are location-aware, Google tries to build location into the mobile versions of these queries.
What I think is interesting about this is the "bored" group. It's neat to see an articulated strategy for delivering content to people just killing time. It used to be that usability and user experience were almost exclusively focused on helping the user accomplish productive tasks. Of course that's still the case but it just goes to show how far the Internet, and by extension web human factors, has been altered by the shift to the Web being a channel for info-tainment.

Currency Concept

Every once in a while I come across a post about redesigning the currency. Today, FlowingData's post in my Google Reader pointed me to a new currency concept from Mac Funamizo. Not only is the design compelling but it accomplishes a lot of the goals required to improve the usability of coin currency. While the focus of the redesign is on travelers to the US, this concept would also improve the usability for visually impaired citizens. Good stuff. 

While I borrowed two images from the site, please be sure to take a look at Mac Funamizo's petitinvention blog. Fanatastic thoughts and concepts.

Still Broken: LinkedIn's Advanced Search by ZIP

LinkedIn rolled out a new interface today designed to improve screen real estate and navigation. I wasn't aware of the redesign until I went out there this morning but immediately noticed the changes. While it's not stunningly beautiful, it's still very functional and that wins all the important awards in my book. That said, one area that still bugs me on LinkedIn is the Advanced Search. 

A lot of times I'll go out to LinkedIn to see if I can find a contact, only to discover through the Basic Search that there are several David Jones (as an example) on LinkedIn. Go figure. Instead of paging through the results, I'll just back up and hit the Advanced Search.This is typically fine if I know the company that the contact works for, but in some cases, I don't know that information. I may just know that they work somewhere near Rome, Georgia. Unfortunately, to perform this search, you can't just enter "Rome, GA" into your search criteria. You actually have to know Rome's ZIP Code.

Yeah.

Harder-Than-They-Should-Be Steps
While I'm sure that's the easiest way for the search to function technically, it's not at all functional for the people using the system, unless of course you're this guy. He probably loves this "feature". But if you're not that guy, at this point in your search, you're going to need to hit the "Lookup" link. But not before re-scanning the page to make sure you're not missing a City/State entry field. (You're not).

Clicking on "Lookup", you're taken to GeoNames, a third-party provider of ZIP codes. Fine, so you type in 'Rome, GA" and you get 5 search results for Rome. 

Now you need to remember back to the other screen  and recall that you are searching a 50 mile radius. Since Rome, GA is way smaller than that, you can pick any of these and you should be fine. Even still, you have to remember that search radius and after remembering you still scan that list one more time just to be sure you pick the right result. These are unnecessary mental reps that ding the usability; the system shouldn't make you think this much. Regardless, once you decide to pick one of the ZIPs, there's no "Use this ZIP" button or anything, you have to physically copy the ZIP, close the window or tab and then paste it (or memorize it or transcribe between screens) into the LinkedIn field.

Now complaining about copying and pasting sounds supremely lazy, but that step is just the culmination of a couple of harder-than-they-should-be steps. This search has just gotten annoying via death by a thousand (or 5 in this case) cuts. The reason these are cuts to the experience is that we're all used to Google (and other smart) searches now.

vs Smart Searches
Compare: I was playing cards with my buddy and he was showing off his new Droid. Specifically he was raving about the Google Search enabled voice dial, proclaiming. "You don't even need to have Pizza Hut in your contacts when you say 'Call Pizza Hut' . . . it just knows where your phone is, looks up the nearest Pizza Hut via Google, and calls that number for you." I had a similar experience with Google Search the other day. My wife and I were trying to send directions to a local park to some friends. The problem was that I didn't know the address of the park. I did, however know the name of a restaurant right next to the park. So in Google Maps, I just typed the destination as "Downwind Restaurant". Sure enough, Google knew where that was.

These are smart searches. The system is working for me in these examples. Contrast that to LinkedIn's search and you see why its geography search is distracting and annoying. Just let me type in "Rome, Georgia" or "Rome, Saskatchewan" "Rome, Italy" and have the system know the what I mean. Worst case, let me simply choose from the top three most likely places.

And sure this Advanced Search commentary is about a very small piece of functionality in an otherwise solid application, but attention to these details is what can set your brand and user experience apart. Better to be set apart by good experiences (Google's search) than frustrating ones.

Kinks in Square's User Experience

There's a new video out today walking through more details about Square. Quick recap of what we know now:
  • Cost: Dorsey hopes to give away the devices for free. I wonder if that's the just the first device or all devices. Since it's so small I could imagine them being easy to lose. 
  • Revenue Stream: Transaction fee-based. Sounds like it's a charge on top of Interchange. I don't disagree with the approach, but merchants are already displeased with Interchange rates as is. Will be interesting to see how willing they will be to accept additional charges.
  • Launch date: Anticipated in March 2010
Some observations from the videos posted below:
  • "That was a LOT for a $3 transaction" - Not sure what the CNBC commentator's name was, but he's right. Watching the process in both videos seems like a lot of steps. While most card transactions have most of these steps, you don't see email entering or signing for low-dollar amounts much (or ever) these days. These elements are speed bumps where no speed bumps should be. The result is a slower transaction rate. In fact, in the second video at the coffeeshop, you can clearly see a cash transaction moving by at rocket speed in the background. Speed is important in retail transactions, particularly retail card transactions. 
  • Can you email the receipt to me? OK, sure, just enter your email address. Really . . . my whole email address? - In my post about the Coke Freestyle, I mentioned stage fright. When there are people in line behind me and I need to enter my email address, which has 24 characters in it, this could be a huge bottleneck. Speed and ease of use are the reasons people use cards over cash. In fact, it's been the subject of a memorable Visa Check Card marketing campaign. While everyone likes to be green, people like speed and ease of use more. The SMS option they provide is better as it's just a phone number you need to enter, and of course the super easy alternative here is to simply provide no receipt. If the latter is not an option, it should be. Another neat option would be to "bump" the receipt to the person's iPhone/Droid but then you've just made the person fish for their phone in their pocket, at which point I'd rather just use my phone to pay via NFC.
  • Lots of handing the iPhone back and forth - Not sure how this handing an iPhone back and forth is going to play out in a busy restaurant/venue with people juggling a paper, a coffee, a muffin, and your store's credit card acceptance device (which happens to be your personal phone also). Hypercom terminals don't break often because they just sit there on the counter all day. Lots of handing back and forth would seem to increase accidents. Perhaps Square (or someone else) should consider creating a docking station for the iPhone for this type of environment? Something that would allow this exchange to take place more easily. 
  • Sign with your finger . . . for $3 dollars? - Expectations these days are that low-dollar transactions will not require a signature. In fact, as almost a card-exclusive purchaser (I don't carry cash) I am always taken a little off guard when I have to sign for anything under about $15. I wouldn't want to have to sign for a $3 dollar transaction. I would imagine this is something that Square would provide as a setting for merchants.
All of these things are fixable so I still remain very interested and optimistic about Square's future. It will be neat to see how that plays out. Anyway, here are the videos of Square in action:

Coke Freestyle: Great Innovation, Broken Experience

There's a Willy's Mexicana Grill close to where I live here in Atlanta that was, to my knowledge, the first restaurant to pilot the Coke Freestyle. It's been in that store for several months now but I only recently went in to try it out. Like most folks, I first read about the Freestyle in a BusinessWeek article on the topic. It's a pretty amazing device that tells a fantastic story about innovation:

  • 30 patents for Coke all bound up into an aesthetically pleasing design 
  • Wireless data transmission of usage trends
  • Cartridges for easier shipping
  • Dean Kamen, who worked on the project, is repurposing the technology for water purification in developing countries
So on the surface, this is nothing short of a huge win for Coke and Kamen. That is, of course until you try to use the Freestyle during rush hour at your local Willy's. Some background and then some observations: 

Setting the scene: I went into Willy's for lunch but also to try out the Freestyle. I got my food, checked out, took my tray to my table and then went to get my drink. In front of me was a business man. In front of him was a 7 year old. In a normal situation, this means I'm about 22 seconds or less away from enjoying a frosty Coke. If you don't know much about the machine, it basically lets you order up anything from Coke's menu. And that menu is pretty deep. So now, some observations:
 
Observation #1 - Novices and Kids are Absurdly Slow
So  this 7 year old is looking at *all* of her options. She's going through all the screens. And I do mean all of them. This is taking some time. She goes into the Sprite category then backs out, looks at the Fruitopia catalog (yes they still make that), backs back out, takes a gander at the Coke options, then backs out, then over to the Powerade selections. I think she's probably seen over 40 selections. And contrary to a recent report, this is not entertaining. This is frustrating. Meanwhile the line is now stacking up and it's been at least a minute. I'm being patient. The guy in front of me . . . he's getting antsy. After a few more exploratory screens, the girl chooses a Fruitopia option. I'm excited because I know she's about to wrap up so I'm getting closer to my Coke. She fills up her glass, sips it - pauses, and then dumps the whole glass out. Now kids are prone to do this with any drink. That's just their way. I did it when I was a kid. I don't blame her. The problem here is that it took this kid a LONG time to go through this experiment. In fast food, playful experimentation like this is not your friend. So she goes back to searching screens. At this point, the line is 5 people long now and it's interfering with the checkout process. The guy in front of me loses it and tells the girl she needs to move it along. And she does.

Observation #2 - Even Pros Are Slow
I'm now about two minutes into my wait but the businessman in front of me steps up and I know I'm close now because we've got an expert stepping up to the plate. He won't be surfing options. He's probably a Coke/Diet Coke guy. Sure enough, he knows what he wants. Diet Coke. But you know watching him go through the screens it seems painfully slow. Again, this is not entertaining - particularly for a UI guy like me. I just keep thinking of how unnecessarily long this process is. I just keep thinking that with the old dispensers, getting a Diet Coke is an 8 second affair. Ice. Diet Coke. Done. Even if you top it off a little. This guy is getting his Diet Coke now, but it's probably taken him twice as long. 

Observation #3 - Stage Fright
But he finished and I finally make it up there and all of a sudden I've got stage fright. I know I just want a Coke, but the line is ridiculous now. I go through the interface but it takes me a second or two to figure it out as well. Again, this should be an 8 second transaction and it's taking me at least twice that long. Plus the experience is cruddy because I'm feeling pressured because I know everyone in the long line behind me is ready to get their drinks too. It's not an enjoyable experience at all. I want to explore the options but I just can't. There's not enough time. On top of all that, I now people are watching me order because they are mentally practicing their routines so they can avoid being a bottleneck when they get there. The worst part. After I finished my Coke (maybe 3 minutes later - I love Coke and drink it quickly) I get up to get a refill and the line is still long. So I have to wait in line for about 2 more minutes, when I know from many years of experience it would have been half that long with the old fountains.

Some of my buddies who have been to this Willy's confirmed all three of my observations. To quote my friend Brian, whose response was completely unsolicited (we were just talking about lunch at Willys - not the machine in particular): "Yea, lunch was good, but I gotta tell you - that new drink machine is a total bottleneck at lunch." 

Something is broken about this experience. How might it be fixed?  A couple of thoughts come to mind:
  • Add more dispensers. The problem with this is real estate. This machine is slightly more compact than the old fountains, but you'd probably need to triple up at least. Unfortunately, tripling the footprint would be much worse for restaurateur, both cost-wise and space-wise. For a business with heavy foot traffic, you need a better solution than "more machines".
  • Provide fewer choices. You could write up an entire post on this (I may). As Barry Schwartz covers in the Paradox of Choice, people have a real problem making decisions when they are confronted with a lot of choices. Add in an interface that encourages exploration and that becomes much more noticeable. Reducing the choices speeds decision-making and makes consumers feel more satisfied with their decisions. Given that this machine is designed to increase options, I doubt this enhancement will be considered.
  • Address your long neck better. So the Freestyle is all about providing access to Coke's long-tail products, but Gerry McGovern tells us we can't focus on the long-tail at the expense of the long neck. This is nowhere more evident than in a time-intensive setting like fast food. So improving the selection and pouring of Coke's long-neck products is probably the route I would go in the near term. In a nutshell, the Freestyle should be speed tested against the old fountain machines. It should be just as easy and fast to order Coke's most popular 5 drinks on the Freestyle as it is on the old machines. These 5  should be extremely easy to order. Maybe these five and the ice button aren't on the touchscreen at all. Don't make pouring a Coke a custom request.
Sure this post sounds ranty, but anyone who knows me knows that there are few things in life that I like more than Coke. I'm just a huge fan. So I'm predisposed to like this innovation. I want it to work. I want it to be a great experience and I think it's close, I'm just not sure it's there yet. Hopefully the beta testing will give Coke some guidance on improving the design of the experience.

I'm curious though. Has your experience been better? How else could it be improved?

Data-Driven Innovation - Google DNS

I came across a rare blog post yesterday evening. It's rare because it stitches together data from a couple of places to help solve a conundrum. In this case, it also illustrated some fantastic vignettes on usability testing, data-driven strategy and innovation. What was the conundrum? Yesterday, Google launched its DNS service but it hasn't been exactly clear why. Google's official response effectively states that "It's good if the Internet is fast because people can be more productive." Sounds altruistic, just like another recent comment from Google about not stealing all of the talent in the world, but Jason Kottke (@kottke) has a different thought on why Google would be interested in accelerating page load speed.

From his post:

Google VP Marissa Mayer told the audience at the Web 2.0 conference that slowing a user's search experience down even a fraction of a second results in fewer searches and less customer satisfaction. Marissa ran an experiment where Google increased the number of search results to thirty. Traffic and revenue from Google searchers in the experimental group dropped by 20%. Ouch. Why? Why, when users had asked for this, did they seem to hate it? After a bit of looking, Marissa explained that they found an uncontrolled variable. The page with 10 results took .4 seconds to generate. The page with 30 results took .9 seconds. Half a second delay caused a 20% drop in traffic. Half a second delay killed user satisfaction.

Some lessons here:

  • Users say one thing and mean another so you have to understand latent/unspoken needs
  • Data is required to make strategic changes
  • Usability testing is fundamental to product success
  • Google's pretty smart (and so is Amazon, which is mentioned in the post as well)

There's a lot to like in such a short post. Full text can be found here.

Traffic light + progress bar = Eko

Interesting concept by Damjan Stankovic, a Serbian designer/innovator. While Damjan lists several green attributes to the light, I'm more sold on the one that deals with stress. One of the fundamental tenets of good usability and user experience is providing the user with an awareness of a system's status. Doing so allows the user to set expectations for system behavior and plan for their next actions. This light accomplishes this sharing of system status information in a very elegant way.

 

From the site:

Eko light is a simple yet, highly practical concept for traffic lights that not only helps preserve the environment by reducing pollution but promotes safer driving as well. Eko can be easily installed onto existing traffic light systems without much effort while significantly improving overall traffic dynamics. There are many benefits of the Eko light, the main ones being:

Less pollution. Drivers can turn their engines off and cut carbon emissions while waiting for the green light. Turning off your vehicle while waiting on the traffic light can lower fuel consumption in the long run.

Less stress

Since you know exactly how long you have to wait you can sit back and clear your head for a while. No need to keep your foot on the gas. Relax.

Safer driving

With the Eko light both drivers and pedestrians can be fully aware of how much time they have left before the light changes and that way reduce the chance for potential traffic accidents.

In any case, I think it's a great concept that's accompanied by several other interesting concepts on Damjan's Relogik site.
