thoughts on iPad

April 30th, 2010, posted in Design, HCI, User Experience

So I’ve had an iPad for the last two weeks, the wifi 32GB model.  Because we need the money for something much more worthy, I’ve decided to sell it, and because they are not generally available here yet in the Netherlands, making a few bucks on it will be easy.

I’ve enjoyed making great skype calls when I was abroad, there are a number of fun games, Harbor Master in particular I’ve found addicting.  I’m a bit vain so I’ve enjoyed the looks I get from people when I pull the iPad out, and it’s especially fun to let people play with it.  I thought the keyboard would suck, but honestly I was able to use it in short bursts and a fairly high speed without too much to learn.  The WiFi reception is better than my 1st generation iPod touch, but not a lot, and not nearly as good as most laptops.

There seems to be a few things that stand out to me about the iPad and why I think it will have a decent amount of success: The User Experience (UX) of getting to the content you want to consume or create is fast, applications are so easy to get and buy, and there are a lot fewer problems of upkeep.  There are a few problems though and a lot of that has to do with it’s size and form factor.  Overall though it’s a win.

From though to action in seconds

From the moment that you think you may want to do something online to the time you are doing it is just a few seconds depending on how close at hand the iPad is.  For those coming from a windows environment this is especially astounding and appreciated.  How does it take your windows based laptop to start up from being closed (which means either sleep or hibernation as a state)?  The fastest I’ve ever seen is 30 seconds.  With most OS X products it’s 5 seconds or less.  This is why smartphones are being used more and more for quick sips of internet content and certain content creation tasks that are fast and easy (like twitter), it’s just easier.  Letting people do what they want to do quickly and easily is a key to a great user experience and has been a key tenet to usability for 20+ years.  Apple has understood that, many others have not.

Yeah there’s an app for that

The app store makes it easy for people who see needs, both large and small, to be able to fill them and make money doing so.  Creating the AppStore and demanding that you link your device to your itunes account in order to use the device (which I personally found very annoying) makes a tremendous amount of business sense.  The experience of the user is seamless and easy.  The experience of the developer is not so much so, but the rewards can be great so people are willing to do it, and once you’ve jumped through Apple’s hoops and given a third of the money to them you have the chance of having your app catch on like wildfire in your chosen market.

I hope my mom gets this

And my dad, and several of my friends who often look to me as tech support.  There are fewer ways in which to do any kind of software damage to an iPad.  Losing files is an impossibility, messing up the OS is really hard to do for most people, and malware and its ilk don’t yet exist and even when they do pop up eventually 95% of it will all be theoretical vulnerabilities.  If all the worlds computing devices were like the iPad (not that I’m saying they should be) then I think we’d see a lot fewer tech support calls and a lot less frustration.  For those concerned about user experience making the life of those who use your product easier because they have fewer problems with it is a big thing.  The balance between the power user who has a certain list of demands and those who just want something to work has been played out many times and in many products.  There have been countless technology oriented pundits who have predicted the failure of this device because of this.  These are a certain brand of techies, geeks, and engineer.  This device, by and large, is not for them.  They will be happier with their android phone, the rumored android based tablets, and their netbooks.

But how do you hold it

I sat playing a game or two or checking my email for 20-45 minutes, constantly shifting the way I held the device or trying to balance it properly on my lap, on a pillow on my lap, on the table so it’s tilted in the right angle, or holding it in one hand and having it get tired and switching.  If I had a cool keyboard this would solve some of the problems, but what about when I want to play a game for a while, and not just 3 minutes?  What about when this is my main computing device for several days and I need to be productive (which generally means reading, writing, and email for me)?  Reading is fine, it’s comfortable, but doing anything more than swiping pages or scrolling and after a short while you’ll get tired or uncomfortable.  My wrists started hurting in strange places.

Thoughts for the UX designer

If you’ve identified, as Apple has, the three top tasks they think people will do (you can’t do user studies on a device that doesn’t exist) then you need to make that experience as pleasurable as possible.  Apple thinks photos, email, and web browsing are the three big things.  Making it fast to get to those things is key.

Email: I admittedly have not used the mail client because the custom iPad gmail interface made me not ever want to attempt that.  Why? Because I need my archive button.  Sure moving things into folders isn’t the best thing ever, but it’s still decent.   In the past we would have talked about number of clicks to a page, now I’m talking time from pushing the power button to being in my email.

Photos: It’s really easy to imagine using this device in the house or in the office as a lightweight computing device that is kept on display as a photo frame, then you just grab it and do something.  The button that turns the iPad into a handsome digital photo frame is prominent.  Syncing to iPhoto is painless and with a fairly large storage, putting many if not all of your photos is very possible.  Sorting through them and looking at them is fun and interesting.  It connects people and puts your photos in a place where they are MUCH more accessible than your computer.

Browsing: Mobile Safari is no Firefox (which is not a compliment) and because it identifies itself as a mobile device and there is no way to turn that off, some sites may not show up as you would like them to.  This is the techie in me speaking.  I don’t think my mom would ever care that she couldn’t change options in google checkout and update her credit card for payment there.  Windows phones have the option of turning this on and off, I would suggest the same here.  Getting rid of tabs and having a palette of open windows seems like a good idea, but there are problems with this for the way I use the device.  First is the button one uses to open other windows or a new one.  It’s totally baffling.  I struggled with it for a minute, pushing every button to see get it.  Even after I knew which one it was I constantly had to remember it as the icon is SO generic and doesn’t indicate what it is.   It’s also placed in an awkward position, and as far as I’m able to tell you can’t move it.  There is also no visual indication of how many other windows are open.  All of these relatively easy to fix problems are not the case on my iPod touch.  I have to say that when I compare the experience to a “real” computer I find it lacking, when I compare it to my iPod, I don’t find it much better besides having more space on the screen.  To me this is not “the best web browsing experience.”  Add to this the fact that content creation is significantly harder in many cases and this becomes a major point of failure for the iPad.

Thoughts for User Researchers

Of course Apple doesn’t really do a whole lot of user research, or if they do it’s not publicized, but what if you were approached by a company launching a product that is really “blue ocean” creating a new market, and they wanted to know what they should do?  It depends on which stage of the product development phase they were in, but let’s assume they have a working prototype.  Do what Apple did: find what you think the top three things are and make those three things amazing.  Post-launch pay A LOT of attention to the way people use the device.  Set up expectations with both product managers and engineers that there will need to be a number of small incremental and very fast updates to the product once you see the device in action.  User observation and studies will reveal a number of issues quickly.  Find ways to funnel all of the feedback on the product back to you and those involved so it can be acted upon.  Your role will be 30% curator/collector of that information and 70% interpreter and evangelist of that information.

Facebook gets groups, when will twitter?

September 10th, 2008, posted in HCI, Twitter, User Experience

It wasn’t part of the new facebook, but recently facebook enabled you to group your friends into different lists.  This is a natural part of someone with a growing list of friends that they may want to keep track of.

Now I don’t even have that many people I follow on twitter just 150 (nice round number, shame to have to add more) but still I wouldn’t mind being able to sort them, and in theory I may want to just message some of them about some events, say some local stuff that is happening here in Bloomington.

This is a natural progression and something that users are expecting, but how does one implement this given the complete fragmentation of the user experience given the tremendous number of clients that have sprung up around the great open API that Twitter has supported from Day 1? This presents a very different set of problems than a more closed network.  I suppose though that in the larger scheme of things as featuers are added to the service and API that because of the huge numer of developers and clients that good uses will catch on quickly as they have in the past.

Usability Challenge 2008 Solution

August 1st, 2008, posted in HCI, New Media, Usability, User Experience

It’s true, today is the Usability Challenge 2008.  I have chosen this page:

Higher Education Resources

This is part of an ongoing project I am working on with the Lumina Foundation for education.  This page is a new way of visualizing and finding a large amount of information.

Lumina has amassed a large amount of publications over the last several years that all are related to their mission which is helping people achieve their potential though education.  People who work in this area directly with youth and adults who want to go back to college are called college access professionals, and my hat is off to these hard working people.  Of course there are plenty of researchers who also work in this are, usually in education departments.  I have met many in both groups.  What all these people including Lumina’s staff members rely on is high quality resources like the ones that have been gathered, but how does one search through these?

Instead of search all of the resources have been tagged (with multiple tags for each item, usually including the year of publication).  These tags have been presented in a tag cloud, where larger text means more things with that tag.  The really new thing is that if you click on one item, it shows you how many things are in that tag, and you may keep on clicking on tags to narrow your results.  The total number is shown at the top on view results tab.  When you are ready you can click on that tab and see all the items.  It is a very cool way of browsing, and the reaction of people once they understand how to use it is very positive.  The problem here is that it is a new convention, with very few affordances.  There is a “view demo” but most users don’t see it, and many users often have the volume down on their computer even when the video comes up.

The solution I am proposing for this particular page is a short lightbox popup that shows the user to click on a tag, then a second and then click view results, showing it graphically, textually and then quickly fading to a point on the screen with a question mark on it.  Clicking on the question mark will replay it slower and have the option for sound as well as givign a link for an even lengthier explanation (which would be around the length of the current demo).

It will be important to use cookies so that once a user has successfully clicked on the view results tab the lightboxed pop-up will no longer show, and that the whole strategy be evaluated regularly to see if it can be improved and when people understand it well enough we can eliminate the lightbox, but keep a pulsing question mark or something like that.

I am also emailing the results of this to Lumina so that it can be implemented. Usability Challenge 2008 is in the can.

Can all these things be design?

July 1st, 2008, posted in Design, HCI, Philosophy of Technology, User Experience

I am part-way through Bill Buxton’s Sketching User Experience, and I’ve read part of the Experience Economy, and of course my course last year on Experience Design.  Add to that the UK’s Design Council finding that businesses that use design thinking and methods are more successful than their counterparts.  Of course I am totally fascinated by what is happening with NextD, and using design to inquire and innovate.

Certainly F@astCompany and BusinessWeek have both picked up on the idea of design, but I’m surprised that this isn’t more widely talked about.

Now add to the mix some of the papers that have come out of the HCI community of practice about research through design and I start wonder. It seems like design is being used in all kinds of disparate contexts, so disparate I wonder if there is any unifying thread to what is being called design?

I of course turn to Nelson & Stolterman’s The Design Way for answers.  They want the book to explain what design is, to instill design culture and design thinking, and I hope to find at least a preliminary answer to my question in this rereading of the question.

If I can answer more simply what design is in all these contexts, I would like to answer the question that has been riddling me for months now: what is the philosophical basis of design (if indeed it has one)? What can research by design rightly say?

All this come back to my original start point, how does design methodology and thinking really impact business? What is it that moves forward like so many think it does?  I think it has something to do with what design is, and where it comes from theoretically.

What is usability in the age of UX? (pt 1)

March 13th, 2008, posted in HCI, Usability, User Experience

I am seriously considering applying for an internship with the well-known (at least in HCI circles) Nielsen/Norman group, I have read much of what both of Nielsen and Norman have to saw about usability, and Nielsen in particular is very anti web 2.0. Well more particularly web 2.0 for no reason. It must add value for your user. Don’t just “go 2 point oh” because it’s cool, but because it makes sense for your organization and especially for your users.

Because newer technologies are… get ready… newer they are untested and therefore best practices and usability standards have not yet been established. As an HCI consultant as well as a designer, what do I say to a client who wants to use some of these newer technologies?

It seems to me that most of us, including myself are technofetishists. Is that a word? I mean we are so enamored with the latest gadget, upgrade, iphone, ianything, graphics card, scripting language, platform independent language, open source environment, that we are totally willing to bend over backwards and accept things that make us do terrible things. Things that are terrible in terms of usability, the environment, and the rabid consumerism that is already so evident in the western world (and growing in other places too, don’t worry I won’t leave you out developing world and asia).

So usability in the age of UX, is it simply that we need to “focus on the user and all else will follow”? Do we need to a little more luddite?
