Text of my SXSW presentation

Here’s the text of my talk at SXSW Interaction 2011, March 12, 2011

It’s about time: visualizing temporality

Slide 1   Hi

My name is Joanna Wiebe; I’m an interaction designer and I work in e-commerce. My husband took this of me in Jamaica a couple of years ago. My web site is onemind.com, and my twitter hashtag for this event is #temporality.


Slide 2   It’s about time

Interaction designers can have an interesting and shamanic role in our global village, and that’s what I’m going to talk about.


Slide 3   What is time?

My immigrant Ukrainian grandfather arrived in Montreal without a watch. He walks up to a man on the street and asks, “Please, sir, what is time?” The man replies, “I’m sorry, you’ll have to ask a philosopher. I’m just a physicist.”

My favorite philosopher, Alfred North Whitehead said “It is impossible to meditate on time and the creative passage of nature without an overwhelming emotion at the limitations of human intelligence.”  IT does boggle the mind. As a matter of fact, if you’ve read Zen and the Art of Motorcycle Maintenance, you’ll understand what I mean when I say I have had a few Phaedrus moments as I prepared this talk.

However, let’s give it a whirl.  Let’s be armchair philosophers.


Slide 4   What is time?

Kids have no idea about time, nor do they care.  I taught my children about clocks, and calendars, and timeliness, and it wasn’t easy.

Now that they are grown, they are time slaves, like me. But sometimes, doesn’t time seem to disappear? When you are very emotional, meditating or praying, listening to music or feeling the earth move?

A French geologist named Michael Siffre went underground for several months to live in a cave without clocks or calendars. He wanted to live “like an animal”, he said.   His days gradually stretched out, starting with twenty-four and a half hours, then more and more until eventually he was sometimes living 48 hours days.  He always thought the days were twenty-four hours, and even though he kept a diary to record his activities during a “day”, he couldn’t tell the difference between these long 48-hour days and a “normal” day.

In a recent interview he said, “It’s the problem of psychological time. It’s the problem of humans. What is time? We don’t know.”


Slide 5    A one-minute history of time

Humans have had many ideas about time over the centuries. In the Medieval world, time – and space — were just a static backdrop for the earth, the center of everything. This geocentric concept is shown in this astronomical clock, built in 1410 in Prague. The blue circle in the middle is the earth.

Copernicus, in the 16th century, taught us that the earth and planets revolve around the sun.

In the Renaissance, Galileo studied the phases of the moon, and developed the pendulum clock.  In the 1700s, Newton described a mathematical, clockwork universe. People imagined God as the Big Watchmaker.


Slide 6   The arrow of time pointing to the end of time

Our next big idea was that the sun is part of a galaxy, among billions in the universe.   The second law of thermodynamics gave us the concepts of entropy, an arrow of time leading to our universe’s eventual cosmic heat death, and an end to time.


Slide 7   The arrow of time and the evolution of time

Charles Darwin drew a picture of biological progress. The arrow of time is pointing forward, he said, and everything’s evolving!  Philosophers, people of faith, and other scientists jumped on his bandwagon. Some people, like Tielhard de Chardin, said that even space-time will evolve into something else.

Slide 8   Mental models evolve

We care about time because we’re going to die. We keep track of time by the rhythms of tides, seasons, sunrise and sunset, heartbeats and menstrual cycles.   These are all local clocks, relative to the observer. In fact, that’s all there is, according to Albert Einstein. There is no universal clock somewhere that keeps absolute time. He said, there’s nothing really, that anyone can point to and say, that’s the past, here is the present, there is the future.  Past, present and future are just ideas.  “Time and space are modes by which we think and not conditions in which we live, ” he said.

And our mental models of time also keep changing. This is not a picture of Einstein, but of Richard Feynman, a theoretical physicist who was an excellent drummer, and whose mental models of time are so evolved that I don’t really understand them.


Slide 9   Four-dimensional design

Some days, it seems like a big part of my work is thinking of ways to let people know that they are just going to have to spend some of their precious time on earth waiting.

As my friend Anne Kennedy says, the web is the only four-dimensional media. And as I say, time is the crux of interaction design.

Slide 10   Digital interaction happens in time

Every digital interaction is a series of actions over time, between two or more agents, human or nonhuman. A person’s keystroke takes a fraction of a second but a system response can take milliseconds, or on the other hand, several days. Uploading my entire hard drive to dropbox.com took four days.   To research this talk, I completed a 15-year interaction by retrieving an article I wrote and published to my web site in 1994, by going to the Wayback machine at internetarchive.org.


Slide 11   Time-boxed interactions

Some interactions are time-boxed. My bank holds me in a live session for only a specified time before I have to login again. My search results at Kayak are only valid for a certain amount of time.   Ticketmaster makes me race against the timer to enter my credit card information and get the seats I want.


Slide 12   Temporal interaction challenges

As interaction designers, we have some time-related challenges.  Designing for different cultures, which hold diverse views of time. Designing interactions that span time zones. And inventing the path beyond technology.  I’ll also talk about some cognitive tools that I hope will help you.


Slide 13   Playing nicely even though we see time differently

If we are designing for global audiences, it helps to know how people of different cultures visualize time.


Slide 14   Time flies like an arrow

Groucho Marx once said, Time flies like an arrow but fruit flies like a banana. I agree about the banana, but I am not sure about the arrow.

What is the shape of time? In our culture, time is an arrow. If you want to give someone the idea that you are goal-directed, that you are fast, that you get things done, then you include an arrow pointing forward – to the right — in your logo.    Of course, the arrow may be pointing us toward cosmic heat death, but whatever.


Slide 15   Cycles, spirals and fractals

Some cultures see time like a wheel, with cycles of recurring events.  Or it’s a spiral, and you can move up or down the spiral with each rebirth.  Maybe –even — all of space-time is an evolving fractal, a simple algorithm that yields infinitely complex patterns!


Slide 16   Customer travel lifecycle

As interaction designers, sometimes it is useful to think of processes as cycles. This is a diagram of the cycle of tasks relating to personal travel, and the databases that track and store each person’s choices at each step in the cycle.

Slide 17   Time orientation

Some cultures have a long-term orientation, which is an outcome of being focused on the future, persevering, and being patient in waiting for the results, saving for the children, ten-year business plans.  China is an example of a culture with long-term orientation. The United States is seventeenth in long-term orientation, last time I checked.

Last year, I redesigned the car rental flow for ebookers.com.  The existing date picker for ebookers was designed by an American, and displayed one month at a time, with arrows to display future months. Because people rent cars a week or two ahead of time, right?  But when I spoke with our UK product manager, I learned that our European customers rent cars, on average, about 56 days in advance.


Slide 18   Sixt calendar

In fact, some of our competition in Europe already had three-month calendars.


Slide 19   Sequential and synchronic cultures

Another dialectic in the way different cultures view time is whether they structure it sequentially, or synchronously. These terms are from Fons Trompenaars, a Dutch consultant in cross-cultural communication.

In a sequential culture, time is definitely an arrow. Time moves relentlessly forward, second by second, minute by minute, hour by hour, day by day, in a straight line, from the past to the future.  Our day is sectioned, so we can do things one after another.  Time is a commodity. Time is money. So a web site for our culture has to be navigationally efficient.

Then there are more synchronic cultures, which I am reminded of when I look at the snapshot on the right from my holiday in Jamaica.  A relationship is valued more than staying on schedule. A date made for a specific time is more like a wish, or a temporary desired outcome based on the now. Designing for a culture with a flexible model of time, we might include browse, search or explore features rather than just linear navigation.


Slide 20   Living without time

It’s fun for me to think about designing software for cultures that think about time completely

differently.  The traditional Hopi and the Mayan cultures, for example, don’t really have any words for “time”.   The Hopi language just puts everything into two buckets – the manifest and the unmanifest.  The Mayan cultures have two interlocking calendars, one with 13 months of 20 days  and the other more of a solar calendar.


Slide 21   Days as gods

Mayan word for “day”, kin, is the closest thing they have – but this isn’t any abstract unit of measure.  Each day has a unique personality, and is creative. In other words, the days are gods.

Another interesting aspect of Mayan time is that time stacks up. Time is cumulative.


Slide 22   Zero point

I cannot omit a mention of Terence McKenna’s view of time, in which time and space are the interplay of habit and novelty.  At the “zero point”, or singularity, on December 21,  novelty will achieve infinity and something will happen – I’m not sure what.

Also, if you’re interested in these things, Google “Schuman Resonance” for a rationale of how by the end of 2012, time will have sped up so much that  “time will stop”, or potentially, be transformed.


Slide 23 Interactions among people who see time differently

If you are designing for a specific culture, you can ask:  What is the shape of time for this culture? Is it an arrow? Cyclical?  Does the culture have a long- or short-term orientation?  Is it sequential or synchronic?  Does this culture have a unique view of temporality?

If we are designing for a global audience, should we just use our own Western approach and force everyone to this standard? Or is there a way we can make the software work for people of many cultures?


Slide 24  An operational model of time that works across time zones

Think about what kind of an inner picture of time you can have, when you can get in a plane and travel anywhere in the world in 36 hours, your body adjusting to any number of the earth’s 24 time zones, not to mention daylight savings time, which starts early tomorrow morning, by the way?


Slide 25   Body time

Here I am, completely jetlagged, at the end of an 18-hour day of traveling.  When my husband took this shot of me, I was no longer in any earthly time zone. I was in Body Time, the aggregate response of my own biology to the shifting temporal landscape of travel.  Haven’t you had that experience of arriving at “breakfast time” when your body is pleading for “bedtime”?  I want someone here today to make the tools, that would help people make sense of this kind of experience, to integrate the personal, bodily-felt experience of time with clock time?  TripIt doesn’t do it for me.


Slide 26   Now zone

We’re here at SXSW, in this room, but I bet at least some of you are also connecting with family and friends in other places. With texts, Google calendar, Skype, and emails, we are living in a new kind of time zone: the Now zone. When we talk with one another, we are together at the same time, NOW — no matter that the clocks say that the times are different.  But when we make plans with someone in another time zone, we always have to make it clear, is that your time or my time?  Like the poet Rilke said, “the clocks move separately from our authentic time.”


Slide 27   Achieving an operational model of time that works across time zones

I read a tweet the other day, from a woman who was complaining that she suffered from “multiple temporality disorder” from living in two time zones six hours apart.

Time systems were set up to be local, and we don’t live local any more. We live global. We need to design systems to help us make sense of these experiences of time in our global village.  Not just engines that translate one time zone to another, although that helps.   I’m envisioning a new kind of calendar.  A new language of time. Clocks that operate on our breath, our heartbeats?  On the internal resonance of the earth?  Got some better ideas?


Slide 28   Finding the path beyond technology

In my lifetime, I’ve gone from using a phone that was a wooden box on the wall, to this little powerhouse device called an EVO.


Slide 29   Finding the path beyond technology

I’ve gone from using a sequential TV schedule in the newspaper, to Amazon Instant video, where I can watch what I want, whenever I want.  Our devices are miniaturizing. It’s up to you to make them cognitively invisible.  Just the way you enter a room today, and the light automatically comes on, and you don’t even think about it, people will use your technology without being conscious of it.  It will be a natural extension of themselves, just part of the ecosystem.


Slide 30   Real-time

Maybe when you think of real-time transactions you think of Google’s Instant Search or texting.  Here’s a different kind of real-time I just read about a few days ago. In the past, farmers in the market for newborn piglets would have to drive to town to check the farmer’s coop bulletin board.  Now, for newborn piglets, just search Craigslist.


Slide 31   Feedback loops

As real-time interactions become the norm for almost everything, we will be able to keep track of the health of people, populations, economies, and environments, and do something about problems more quickly.  Like Katrina or the earthquake and tsunami in Japan. Real-time will give us the feedback loops physicist Friz Capra talks about, to regulate ourselves as a planet.

Physicist Fritjof Capra has said, “. . .a community that maintains an active network of communication will learn from its mistakes, because the consequences of a mistake will spread through the network and return to the source along feedback loops. Thus the community can correct its mistakes, regulate itself, and organize itself . . . The pattern of life, we might say, is a network pattern capable of self-organization.”

With everything you learn that makes you a better interaction designer, you are working toward building an active network of communication around the world.  You are moving our systems toward the day when we can fluidly talk with one another in real-time. Of course, it will still be up to each one of us to decide to have goodwill and practice it with one another. But you can give us the possibility of economic and political systems in which everyone can participate in open, global interdependency. You’re moving the needle toward Marshall McLuhan’s “brand-new world of allatonceness” in which time has ceased and space has vanished, where we will be, as McLuhan has said, profoundly involved with one another.


Slide 32   Latency, session management and timeouts

But, we’re not quite there yet. Last night, I sent my husband a text message, and he responded. My phone indicated that he had texted back, in fact, two minutes before I had sent him the original message. Now, that’s latency!

To get to true real time, much has to be done on the front end AND our back end systems.  And as designers, we need to understand our existing back end systems so we can make the best use of them.

Here’s my husband Tim, eating chips on the balcony of a hotel in Spain. The picture reminds me of the frustrating afternoon I spent trying to book that hotel, getting timed out over and over again.

The exciting part was that I worked at Orbitz, so I had a chance to help fix the timeout problem.

Why? I asked.  Why these short sessions?  Why can’t we just hold everyone in session indefinitely?

I learned that each hotel search called on a byzantine collection of global distribution systems for hotel inventory.  Orbitz servers stored this collection of search results to create a stateful session from the essentially stateless behavior of the web. Our power wasn’t metered, so it wasn’t a matter of electric cost.  But increasing session lengths or having more sessions had an impact on server performance. There were load issues at peak times of the day.

Also, it’s not safe to prolong everyone’s sessions indefinitely if credit card information has been entered.  Travel data and prices quickly become stale, and there are latency issues with continually refreshing the data.

First of all, we increased session time across the board as much as we could without affecting performance or latency.  Then we also timed out different pages in the booking path based on historical behavior of our key market segments. If the customer clicked on a select group of triggers, they would be asked if they would like to see refreshed results. We still had the same old awkward backend systems but we had improved the user experience through interaction design.  Bookings went up.


Slide 33   Tools for time work

To do brilliant work with temporal issues in the user interface, here is a short checklist of cognitive tools you might find useful.  By the way, it helps me to think of interaction design like composing music, because a lot of the same fundamentals apply.

–        Sequence

–        Pacing and rhythm

–        Duration

–        Interval

–        Patterns

–        Priority


Slide 34   Sequence, and direction

To be an interaction designer, we have to be masters of sequence, and the direction of sequence, the subtleties of cause and effect. This is the cover of the graphic adventure video game Myst, in which the player explores an environment to see which causes will trigger helpful effects.  As designers, how do we know when to make an effect explicit, and as discoverable as possible?  How do we know when should we make the effect a learnable surprise, like in Myst?


Slide 35   Process flows show sequence

This is an example of a process flow I designed for a single screen of a back-end tool, to try to tease out all the conditional steps in a process, and which causes would lead to which effects. You don’t need to read all this – I am just showing you this to illustrate just how complex these box and arrow decision trees can get.


Slide 36   Functional descriptions that show cause and effect

And here’s a more traditional information architecture wireframe, again annotated with functional specifications so the developer knows what each trigger is supposed to do. Again, don’t try to read this.


Slide 37   Conceptual Graph Structures

Another tool for working with sequence is a cognitive task analysis method called Conceptual Graphing.  In this method six kinds of nodes are connected by a formal grammar via 18 types of arcs, setting up semantic relationships. This method is based on research into how people tell stories.   Here’s a hand-drawn example from my friend Scott, who introduced me to this method.  For a deeper dive on this, check my web site. http://onemind.com/2010/01/27/conceptual-graph-structures-part-1/


Slide 38   Pacing and rhythm

Are you designing a roller coaster or a tea party?  What’s the most efficient rhythm of work for the typical person?  What pace is going to be the most fun? Every journey has its natural pace, including the paths through an e-commerce form, a game, or a web site.  Push it too hard or go too slow, and it’s just painful. Or even impossible. Then also consider, are the people novices or experts? Are they multi-tasking or will they be giving this effort a single-minded focus?

The mind can absorb no more than the seat of the pants can endure. Is a group of tasks something that a person can do in a single sitting? Or are you going to make them get up several times to go find information that they don’t readily have at hand, interrupting their pace?  Are you going to make someone click “Next” and “Next” and “Next” without giving them clues as to how long this is going to take?  Are you going to interrupt them with interstitials and progress bars?
Slide 39 Duration

A time-related user interface problem, which I don’t think anyone has solved, is how to visually display an array of flights with their relative durations, as well as the durations of stopovers, overall elapsed time, time between flights, actual time in the air for each portion of the flight, time zone shifts, probability of delay, not to mention depart and landing times.  This is a screen grab of an experiment in how to display flight duration.

Slide 40   Interval

When I began working at Orbitz, one of the first time-related issues I ran across was that there was not a common understanding of the intervals in a person’s itinerary. So I put together this diagram of flight components so we could start to think about these intervals.


Slide 41   Patterns

Time gives us context for understanding data.  In time series visualizations, we can see how things change over time.  Are there trends, patterns? What is the rate of change?

There are many time series display methods: from line graphs to heat maps. Stephen Few, Ben Shneiderman, Edward Tufte, and many others have done excellent work in the field of time series display.


Slide 42 Lifelines

Here’s an example of some conceptual work Shneiderman was involved in at the University of Maryland, to use interactive time series display for personal medical records. A single screen displays an expodable timeline of a person’s entire medical history.


Slide 43 Priority – implicit or explicit

Within the sequence, what should people do first?  TurboTax gives you an implicit priority by the sequencing of the icons, and the 3-D, time-as-an-arrow diagram. An explicit priority of tasks can be shown through numbering. A wizard interface imposes priority.


Slide 44   The interaction designer as shaman

Speaking of wizards, this is Tim, the Shaman, from Monty Python and the Holy Grail. Tim says to the brave knights, “Follow. But. Follow only if ye be men and women of valour.“

I like Esther Dyson’s comment, “I’ve always done things I wasn’t ready for.”  Whether or not you feel you have the skills, or the experience, or the background, be brave. Help people connect across cultural differences. Across time zones.  Make technology that’s easy as breathing.  Invent new calendars and clocks.  This kind of work will help people do what they want what’s most important to them.  Which is to love and be loved by others.  To be in relationship.  To have some fun. We want to work, play, support our families. And we want to do it in a way that we aren’t piling up five pounds of trash per person per day the way we are now.  So that the polar bears can live, and the baby birds aren’t full of plastic bits, and the air is clean.

My vision is of a computing world where we are help be these kind of people – and ever more so – in a way that we’re not thinking to ourselves, “now I’m using a computer,” or, “now I’m running software applications now,” or, “now I’m using a wireless network device.”  My vision is that everything’s going to be effortlessly integrated, so that we’re just doing the things humans like to do – work, play, learn — eat, pray, love – and the tools we are using to get things done just fade into the background of our awareness.

Slide 45   The power of a vision

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.

– Antoine de Saint-Exupery

Looking back over history, we can see that new designs for clocks and calendars have often been the precursor of some kind of revolution or another.

Time is our sandbox. We can expand time.  We can make time fly. We can bring people together in the Now zone, to heal and to help.

This kind of work we can do seems shamanic, to some, because we see a pattern where others only see a pile of rocks.

The future user experience

Harvey Hubbell, inventor of the electric plug

When you fly into San Francisco at night, you see a brilliant mosaic of sparkling electric lights stretching for hundreds of miles from the Pacific Ocean to Yosemite.

Whenever I see a sight like this, I think of a man named Harvey Hubbell.

Harvey Hubbell was a Connecticut inventor who made it possible for us to easily use electricity. He was walking in New York City about 150 years ago when he came upon a penny arcade which was just closing for the day. The arcade included an electrically operated game where two boxers, who traveled along slots in the floor of a miniature boxing ring, threw right or left uppercuts at each other with the touch of a button.  Harvey watched through the window as the janitor struggled to detach each of the power supply wires from separate post terminals extending outward from the wall, so he could move the big game to the side and sweep under it. Then the janitor sweated even harder to identify each wire and its proper terminal post, make the reconnections, and check each terminal so there wouldn’t be any short circuits. At that moment, Harvey had a flash of insight.

He saw a product with individual wires that would be permanently attached in the right sequence and correct  polarity, which could be easily and safely connected or disconnected. In other words, plugged in or out. Yes, Harvey invented the electric plug. He also invented the pull chain light switch and the flip light switch and a bunch of other things that make it easy for us to use electricity in our daily lives. With his brilliant, user-centered, incremental advances, I think of Harvey as the prototypical user experience designer.

And other inventors have moved us even beyond that. For example, in some rooms you just walk in and the light turns on by itself. And you don’t think about it.

What are some other technologies besides the electric plug, or the light switch, that are so much a part of your life that you don’t really think about them as you use them?  I’m talking about commonplace stuff that we use every day.  Myself, I like 3M’s Post-It notes.

In 1876, a Western Union memo proclaimed, “This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us.”

When I was a child, living north of Saskatoon, Saskatchewan, on the south wall of our living room  was mounted a rectangular wooden box, about eighteen inches by ten inches, and about five inches deep. A black round thing stuck out from the front of it. It had a little wooden shelf for a small notebook and a pencil. On the side of the box was a black tubular thing which was attached to the box with a cord.  There was a bell on the box, which would ring randomly and unpredictably, scaring the wits out of me. Then my mom or dad would run over to the box, hold the tubular thing up to one ear, and speak into the round thing.  Astonishing.

Today we pretty much take our mobile phones for granted, but this technology is pretty new.

Martin Cooper

Here’s a picture of Martin Cooper, who thought up the first cell phone in 1973,  and led the 10-year process at Motorola of bringing it to market.

My phone today -- an Evo

Today my phone is still a rectangular box, but it fits in my pocket and I can use it to talk to other people — and take photos, listen to the radio, reserve an airline ticket, play Scrabble, read the New York Times, and much, much more. My piece of mobile communications technology, called the Android EVO, runs on Sprint’s HTC 4G network, with a touch interface with haptic feedback. It’s got voice control that allows me to speak what I would like the phone to text to my husband, in case my hands are busy at the moment typing or baking a pie. A voice inside the phone gives me turn by turn directions on the highway. When I use my phone to surf the web, with Google’s new Instant search predictive technology, search results pop up on screen with my first keystroke, updating as more letters are added to the word or phrase being searched. When I type in “hotel room”, the darn thing knows where I am, for instantly a lot of hotels are displayed in my immediate vicinity! This is all so amazing!

Makes me wonder…what personal communication device is my granddaughter going to use when she’s a teenager? When she’s our age?

In 1943, the chairman of IBM, Thomas Watson, made a prediction, saying, “I think there is a world market for maybe five computers.”

My first computer

How many computers do you have, including mobile devices? I mean, that you actually use? In our home, we have three laptops (two Apples and one company-issued PC), three Sprint EVOs, an iTouch, a iPod, a Wii, and an archive of old Macs and PCs in our storage area, going back to my first love, a sixteen and a half pound “portable” 512K Mac which I bought in 1984 for $3,300.

Analysts at Morgan Stanley expect mobile Internet usage to surpass stationary browsing by 2015.

According to Mary Meeker, the lead analyst at Morgan Stanley who developed this prediction, the mobile Web has grown at a significantly faster pace than desktop usage (such as dial up or broadband).

As she puts it on one of the slides in the report: “Rapid Ramp of Mobile Internet Usage Will be a Boon to Consumers and Some Companies Will Likely Win Big (Potentially Very Big) While Many Will Wonder What Just Happened.”

The companies that win will offer location-based services, time-based offers, mobile coupons, push notifications, personalization and relevant search results, and more.

IDC says that over 200 million smartphones (or devices with the ability to run third-party applications) will be shipped in 2010.

Gartner says by 2011, over 85 percent of handsets will offer web browsers.

Location is the holy grail of the mobile experience. One of the major developments this year has been the availability of free navigation systems on mobile handsets.

Business travelers used to use expensive navigation systems, or paper maps, 411-info, or simply stopped to ask for help as the chief way to find restaurants, hotels, and businesses, or navigate where they wanted to go.  Because these methods historically were more error-prone and time consuming, customers did more upfront planning to “de-risk” their travel experience.  Now with the advent of trustworthy, nearly always accessible location-based services, travelers can do a lot more of their travel planning and decision-making on the fly, often when they are in market as opposed to prior to the trip.

Being present at the moment that a need exists makes the mobile experience more relevant.

The big change is that travel-planning and booking will happen anytime, anywhere – even up to the last minute.   With location-aware services out there, everyone (including businesses) will make their communications more relevant, based on where the traveller is physically located, at any given point in time.

Jupiter predictions for wireless devices THIS YEAR include the delivery of mobile applications through the “cloud” on an on-demand basis. All the processing will be in the cloud and not on the desktop. Cloud computing is a general term for anything that involves delivering hosted services over the Internet – whether infrastructure, platforms, or software.  The name cloud computing was inspired by the cloud symbol that’s often used to represent the Internet in flowcharts and diagrams.  A cloud service is sold on demand, typically by the minute or the hour; it is elastic — a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer or a mobile phone, and Internet access).

Touchscreens will be included in over 60 percent of mobile devices shipped in Western Europe and North America in 2011. Other touchscreen trends are said to include the use of multi-touch interfaces and haptics (the machine vibrates or moves in response to your touch).

At home I have a white box called a Wii, and a wand. When I wave the wand at the white box, I have an experience of bowling, or playing golf, or tennis.  They call that gestural interface technology and that may be coming to your mobile phone too. You won’t even have to touch it to make it do something.

Paper thin flexible devices

Our future phone might not look anything like a phone. It could be thin like paper, and able to bend, fold and be flexible enough to store in a pocket. Taiwan-based Industrial Technology Research Institute, (ITRI) recently won a top prize in the 2010 Innovation Awards contest for a manufacturing technique that allows mass production of high-quality displays on flexible materials. The idea for their technology came from watching chefs prepare paper-thin Taiwanese pancakes, which can be easily peeled from a pan at high temperatures.

The UK company Dial-a-Phone recently put out a list of what it deems the “top 10 ridiculous ideas about future of mobile phones”:

  • Datoos (DNA-based tattoos)
  • Subcutaneous mobile phone implants.
  • A mobile phone and headphones in one
  • Mobile phones with nanotechnology
  • Multi-sensory phones
  • Jewelry that makes calls
  • Smartphones with multi-core processing
  • Wind-powered mobile phones
  • Mobile phones powered by fuel cells

These ideas might seem ridiculous to some, but on the other hand, you might be making a flight reservation from your earrings in a few years. Or, from a small sheet of paper in your billfold.

Or even directly from your brain!  A brain–computer interface (BCI), sometimes called a direct neural interface or a brain–machine interface, is a direct communication pathway between a brain and an external device. For example, Mindball is a product developed and commercialized by a Swedish company, in which players compete to control a ball’s movement across a table by becoming more relaxed and focused. And recently a machine has been developed to translate thoughts into speech in real time.  A 26-year-old man who had a brain stem stroke at age 16 was paralyzed except for slow vertical movement of the eyes in a rare condition called locked-in syndrome.  Scientists implanted an electrode in his brain, neurites began growing into the electrode and, in three or four months, the neurites produced signaling patterns that were wirelessly transmitted and via a speech synthesizer, the man was able to communicate.

George Burns  said, “I look to the future because that’s where I am going to spend the rest of my life.” In my role as a user experience designer for an online travel company, I spend my hours looking to the future, open to flashes of insight that might make the travel experience more like play, less like work.

A few years into the future, I’m going to be searching for and booking and managing my travel on some kind of mobile device but it will not be anything like the one I use now.

I will make a special gesture with my fingers and the device will expand or contract to any size I need for available conditions of space and light. When I say, “find me a flight”, the device will make an educated call on where I am going, because it’s been watching my emails and listening to my calls, and knows my probable destinations, and maybe even the dates of my upcoming trips.  The web sites that I visit will have been learning my behavior patterns and will prepared to offer me very relevant, custom experiences.

I say, “I want a hotel in Seattle on Thursday,” and the paper becomes 3D, with a map of Half Moon Bay, with tactile cues for the different hotels that have rooms on Thursday and that are in policy for my company.  Touching the Ritz Carlton, my flexible paper-like mobile phone/computer/personal concierge projects a panoramic moving image of the hotel rooms on a nearby wall. By making other finger gestures, I can zoom in and look at the room in detail, even looking out the window to make sure the view is ocean-side and not parking-lot side.  I’ll catch a whiff of salt spray. An ocean-side suite has been displayed to me because the booking system knows my past hotel booking behavior and has made a pretty good guess as to what I would like.

Technology is changing, changing fast.

But are people changing?  I don’t think so. There are some things people have always done and will always do, and that doesn’t change no matter how sophisticated our technology gets. Above all, people continue to want to love and be loved by others.  We want to visit each other. We want to have some fun, learn, grow, challenge ourselves a little – or a lot. We want to work, play, support our families.

My vision is of a computing world where we are enabled to do all these things – and ever more so – in a way that we’re not thinking to ourselves, “now I’m using a computer,” or, “now I’m running software applications now,” or, “now I’m using a wireless network device.”  My vision is that everything’s going to be effortlessly integrated and FAST – so that we’re just doing the things humans like to do – work, play, learn — eat, pray, love – and the tools we are using to get things done just fade into the background of our awareness. Just the way when we walk into a room, a light automatically turns on and we don’t even think about it.

Is that a vision you’d like to see? Does that excite you?

Beam me up Scotty!

This is the text of a talk that I gave Oct. 12, 2010, at the Ritz Carlton Half Moon Bay, California, to a group of travel management executives.

Personas for the design of learning systems

Brad Colbow cartoon on Persona Development

The two panels shown above are from Brad Colbow’s comic strip, The Power of Personas, from his Think Vitamin blog.

I am including them here because I am going to take a break from all the theory I’ve been posting the last few weeks, and share a bit of what I have been doing at work.  I have been developing a cognitive framework for persona development.

What, you may be asking, is a “persona”, and what use may it be to the design of learning systems?

In the world of user experience design, a persona is a mental model, or archetype, of a class or type of user.  It’s a one-page psychological profile of an imaginary person who represents a distinct set of goals and the behavior patterns that may cascade from those goals.  A persona is methodically crafted from a synthesis of rigorous research. Getting to know a persona is like reading a character sketch for a person in a novel. Developing personas helps my company, an international online travel booking site, focus  on its users. That’s because you can relate to the persona as an individual human being.

What a persona is NOT:

  • A persona is not a “role”,  which focuses on tasks, and which does not incorporate goals as an organizing principle for design thinking
  • A persona is not a collection of demographic information or a “market segment”
  • A persona is not a representation of a niche user, such as users who prefer a specific channel such as mobile, or users who buy a specific type of package.
  • A persona is not a weapon or rhetorical tool whipped out at strategic moments to make a point.

Why should learning designers use personas?

Personas were brought to the attention of user experience designers by Alan Cooper in his 1999 book The Inmates are Running the Asylum. He pointed out that personas:

  • Help team members share a specific, consistent understanding of various audience groups. Data about the groups can be put in a proper context and can be understood and remembered in coherent stories.
  • Help designers propose solutions guided by how well they meet the needs of individual user personas. Features can be prioritized based on how well they address the needs of one or more personas.
  • Provide a human “face” so as to focus empathy on the persons represented by the demographics.

In his 2007 book About Face, Cooper went on to say that personas:

  • Determine what a product should do and how it should behave. Persona goals and tasks provide the foundation for the design effort.
  • Communicate with stakeholders, developers, and other designers. Personas provide a common language for discussing design decisions and also help keep the design centered on users at every step in the process.
  • Build consensus and commitment to the design. With a common language comes a common understanding. Personas reduce the need for elaborate diagrammatic models; it’s easier to understand the many nuances of user behavior through the narrative structures that personas employ. put simply, because personas resemble real people, they’re easier to relate to than feature lists and flowcharts.
  • Measure the design’s effectiveness. Design choices can be tested on a persona in the same way that they can be shown to a real user during the formative process. Although this doesn’t replace the need to test with real users, it provides a powerful reality-check tool for designers trying to solve design problems. This allows design iteration to occur rapidly and inexpensively at the whiteboard, and it results in a far strong design baseline when the time comes to test with actual people
  • Contribute to other product-related efforts such as marketing and sales plans. The authors have seen their clients repurpose personas across their organization, informing marketing campaigns, organizational structure, and other strategic planning activities. Business units outside of product development desire sophisticated knowledge of a product’s users and typically view personas with great interest.
  • Personas also can resolve three design issues that arise during product development: the elastic user (the user is anyone you want it to be), self-referential design and edge cases.

By now you might be saying, “Ah-ha, I see how using personas could help the designer of learning systems understand users, and thus design more sensibly and empathetically.”

So I don’t really have to spell it out, do I?

What is the risk of not using personas in our work as designers of learning systems?

  • We won’t understand our prototypical learners, and their goals, attitudes and behaviors
  • We may be self-referential in our design
  • Design teams won’t share a common understanding of  various audience groups
  • Feature prioritization is not based on user needs
  • Other mental models will be needed to support feature development choices
  • We may be way off the mark when it comes to testing with actual people
  • The user becomes elastic (anyone you want it to be at the moment)
  • We may have trouble defining edge cases
  • We might build what users ask for instead of what they would really use
  • Design cycles may be lengthened
  • Product quality may be impaired
