Predicting the future must be human-kinds second oldest profession.  I try to avoid falling into the trap of prognosticating anything, preferring to use a more Darwinian approach  in preparing myself and my organization for what will come (flexibility, adaptability, etc.).

Whenever someone does ask me about the future of technology —  “What do you think the next big thing in technology will be?” I have a ready answer. I respond with something ridiculous and humorous. “Smell-O-Vision!”, I would say, trying to make the point that it is futile to try to predict the unpredictable.  How anti-predictive I thought I was.

Today I learned that I’m going to need to invent a new snarky response to that question. Thanks to the innovators at the Oscar Mayer Institute for the Advancement of Bacon, a marketing campaign has just been launched to promote a real-life smell-o-vision device. They have built a hardware plug-in for the iPhone that enables an alarm clock to wake you with the smell of bacon.


At first, I thought April fools day had come early. But on checking this out, it appears that this is legit — it is a real product. Snap the device onto your iPhone, set the app for the time you want to wake and put the phone down on your night stand. At the designated hour, the device will emit puffs of vapour scented like fresh cooked bacon.

Well, it turns out the folks at Oscar Mayer are not the first to think about bringing scent to the user experience. PC Magazine has an article on 10 oderific gadgets and gizmos that you can buy today which lever what scientists believe is among the oldest of all our senses.


The Science of Smell

According to a New York Times book review of the aptly titled Smell,  the nerve bundles branching backward from our nose are connected to the evolutionary ancient parts of our brain. The olfactory system also connects more or less directly with our limbic system — the part of our brains that deals with our emotions. Smelling something generally leads to emotionally nuanced and even instinctive actions. Hormone production is also triggered quite automatically through the strong connection of olfactory nerves to the pituitary gland. The upshot is that what we smell influences our general bodily function in an way that we may not be concious of. According to the book review, before we can rationalize or verbalize what we smell, but have an immediate reaction and start to act in accordance with it.

Personally, I can relate having recently spent a year suffering from anosmia . What I missed most during that year was not the joy of tucking into a fragrant glass wine nor was it wafting up the waves of scents from a bouquet of flowers. What I felt was a general feeling of missing the mini-surprises of unsought emotions.Poem That is, I was not pleasantly distracted from my daily activities when I caught a waft of my wife’s perfume as she walked by. I was not pleased by the clean smell of a freshly washed towel after my shower. I was not alerted to the state of cleanliness (or lack thereof) of the public toilet I walk into at the Hospital I work at. I could walk past a bagel shop and not know I had done so. No sensation of sweet baking. No reflexive mouth watering. No gentle hunger pangs.

Now that I can smell and taste again, I have become very attuned to the little mini-emotions that pop into my conciousness all during the day. So much richness has been restored to my every day life. I am happy to smell and to feel the emotions induced by smell — even the negative ones brought on by stinky garbage.

The Emotion of Smell

Our sense of smell is a very under appreciate human sense.  Even reading about smells can induce emotion and memory. See if you can read the poem on the left by Christopher Morley without your limbic system triggering a pleasant emotion or two.

If you found yourself experiencing the warm recollections of the smell of ripe apples and camp-fire smoke, this little poem provides some subjective proof that our nose is an important part of our emotion-inducing senses.

I don’t think I’ll be a customer for the bacon vapour alarm clock gadget, but it’s nice to know that the frequently forgotten olfactory system isn’t totally ignored in today’s personal technology maelstrom.

Quick, choose one: Takati or Ulumo?

Filed Under Tech

Welcome to the world of User Interface Design. Here is your first assignment:

You are tasked with building OTN’s next great telemedicine service which will be delivered on PCs, smart-phones and tablets. Thousands of users are going to click on your service. Your service consists of two different applications (‘apps’). The first app is called TAKATI and the second app is called ULUMO (don’t worry what these strange names mean, play along). Your job is to choose a graphical look-and-feel that will make it apparent to users which app is which.

Which of the two graphics above do you choose to be the icon for the TAKATI app and which one for ULUMO? After you have chosen, take a moment to reflect on your decision. Was choosing easy or hard? Why do you think a shape and it’s colour just seems to fit a particular word? What would happen if you reversed your decision – would it make a difference to how usable our service was?

Over the last few years the Ontario Telemedicine Network (OTN) have been increasingly driving more of our service to the Internet. Our members can now get a broad swath of information about how to use telemedicine through on-line documents, check-lists, policies and member agreements. They can search and find healthcare providers and sign-up for educational opportunities on-line. They can schedule telemedicine encounters. If they need training, they can get it through a web-based multimedia at any time. They can launch videoconferencing events from the web or smart-phone. Have a videoconferencing encounter on their PCs over the public internet. We have a lot to be proud of, but we are only just beginning. In the next several months, we will be bringing all these isolated services under one web framework and one look-and-feel. Harmonizing all these services into one Telemedicine Centre will bring coherence and functionality as our users have never seen before.

As the little assignment above demonstrated, it can be important how you name things, what colour you use and what they look like. User interface design is about these issues and a lot more. Think of all the times you have been frustrated by poor user interface design on business-oriented websites or apps. Who has not had an experience an inability to find information on-line, to specify the correct product to purchase, to navigate a complex on-line form or to find out what to do when you run into trouble. Bad design leads to a bad user experience. And a bad user experience can lead to disillusionment and abandonment. Designing good graphical user interfaces is key if we want our users to adopt our services.

According to Jacob Nielsen, The distinction between user interface and user experience is subtle but important:

We design the user interface: screens, error messages, forms, commands, etc. But users experience the system as a whole, comprised of both the design and the implementation as well as many other components, such as network delays, which can ruin response times and degrade user experience as much as bad design can.

How can we ensure that our users have a positive and productive experience using our on-line services? Many of us at OTN already have aspects of the user experience at the centre of our job descriptions. However, the graphical user interface is a new thing for us. It will play in increasingly important role in user experience as we release more service through PC/Phone/Tablets and it needs its own special attention.


To this end, I have formed a User Interface working group to kick-start this work. We have been meeting and working on the user interface and user experience for our PC-based videoconference portal and the Telemedicine Centre with some great results (coming soon — be patient).

We all understand how important it is to make on-line services ‘easy to use’. However, making things easy is not always easy. It takes design expertise, effort and persnickety attention to subtle but important detail. With the formation of the User Interface working group, we now have a team which focused on the User Interface aspects of our user’s experience making sure our on-line services are the very best they can be.


An Innovation Doctrine

Filed Under Tech

Lately, I have been reading a lot to better understand how my organization could respond to the rapid personalization of healthcare, mobile health computing (mHealth), social networking and ubiquitous communications.

As I was researching, I recalled an important insight in one of the books I had read by Dr. Jared Diamond. In his excellent book Collapse: How Societies Choose to Fail Or Succeed, Dr. Diamond outlines the major problems that societies historically have faced and how they mis-handled these problems:

• Failure to anticipate a problem before it arrives
• Failure to perceive it once it has arisen
• Failure to attempt to solve it after it has been perceived
• Failure to succeed in attempts to solve it

Dr. Diamond was discussing problems like major ecological, political or economic misteps that have brought down entire civilizations. However, I thought that his succinct 4-step failure mechanism applies equally well to other problems such as a disruptive technology or a fundamental market shift.
On thinking about this passage, it occurred to me that if we transform Dr. Diamond words in a positive way, we get a doctrine of innovation:

• Anticipate an opportunity before it arrives
• Perceive the opportunity once it has arisen
• Attempt to exploit the opportunity after it has been perceived
• Succeed in exploiting the opportunity

Jarad Diamond’s history lesson is that we should not be complacent in the face of major change. My modern take-away from this is that yes, we should be ever vigilant of disruptive change. But also, we must be open to major opportunities. Once we see a strategic opportunity coming, we must energetically embrace it.

This innovation doctrine is one of the ways to ensure an organization that embraces change, is responsive and sustainable, and an active contributor to an ever-changing health system.

Baroque Cycle – 2nd Rotation

Filed Under Science, Tech

I just finished reading the remarkable “Baroque Cycle” by Neil Stephenson.

The Baroque Cycle by Neil Stephenson

It’s a 3-volume, 8 book, 3,000 page historical fiction covering a pantheon of characters, in the late 17th and early 18th century. It’s about international trade, wars, espionage, heists, slave-trade, cryptography, enlightenment, alchemy, the Newton-Leibniz calculus controversy, piracy, Cromwell, vagabonds and lords, monetary policy, the age or reason, English and French monarchies, baroque architecture and city planning, King Salomon’s Gold, South-East Asian warlords, duels, unrequited love, the Plague, horology, Tzar Nicholas, buried treasure, Catholic-Protestant-Puritan battle for ascendancy, sea voyages, hand-to-hand combat with period arms, the Inquisition, the fire of London, The Royal Society, and 20 other joyously interconnected ideas.

What is more it is imbued with colorful heroes and villains, many based on unimaginably detailed research of real people living at the time. It carries on at a good pace and many sections leave you smiling and shaking your head at the vocabulary and virtuosity of this remarkable author.

The Baroque cycle is an epic masterpiece by a genius.

It is so good, that this is the second time I’ve read it.

Preserving History is Not a Spectator Sport

Filed Under Tech

Yesterday, I spent the whole day copying home movies off of DVDs onto my computer hard-drive.  I was doing this as an act of historical preservation, one of many that I have done over the years. As I was feeding disk after disk into the computer, I reflected on the effort needed to fight the ravages of time …

Pop Quiz: Name Your Great Grand-Mother

As my family’s self-appointed archivist, I have taken it upon myself to capture my family’s narrative, images and memories. Over the years I have developed an extended family tree, have recorded miles of video tape, have transcribed thousands of words of narrative, have interviewed family members on audio tape and have taken thousands of pictures. I have also documented a mission of rediscovery where I joined my father on a trip to Poland to visit the village and the people who saved him during the war.

As the child of a holocaust survivor, I know too well that the memory of people and of entire human societies easily vanish. I have made it my mission to capture and record as much personal history as I can. I now know quite a bit of my parent’s story. Less of my grandparents. And sadly, still almost nothing of my great-grandparents. This is true of most people I know, and we are the poorer because of it. So, for the sake of my children (and their children), I have adopted this archivist quest so they don’t suffer from historical myopia where only the last generation or so is in view at any one time.

A Menagerie of Media

Starting in the early 80’s, I started taking photos on cheap point-and-shoot cameras and gathering the prints into albums. At the time, film negatives were a nuisance and sadly were never kept. Later that decade, I moved to 35mm slide film for the superior quality and the experience of viewing images up on a big screen.  My grandparents and my uncle had taken beautiful B&W photos and large format colour slides, so I also gathered and cataloged these as well.

In the late 80’s I bought a film camera that used state-of-the-art cassette tapes. I took hours of video of my sons growing up, family events and of goofy canoe trips with my friends. During the 1990’s I upgraded to a 35mm still camera and to a move compact video camera. In the 2000’s I upgraded again to digital cameras and digital video.

Video Cassette Video Mini-Cassette
VHS Paper Photos
35mm Slides


I also gathered old letters, official documents, postcards and other gems of the lives of my parents and grandparents.

My wife is my co-crusader in the fight against the ravages of time and memory. She keeps a daily diary, writing her life’s story and the interplay of her family and friends. Every night she writes a page or two. Every year, she starts a new volume. In the basement are boxes with over 30 volumes, as she has been writing without pause since she was nine years old.

Entropy Never Sleeps

Paper letters, diaries and photographs along with magnetic tape and plastic DVDs all have life spans determined by physical forces. According to the experts, well managed, acid-free cotton or linen paper can last over 500 years.  Magnetic tape has 25 years before the content is at risk. Interestingly, even DVDs are not expected to last more than 50 years. But even these numbers can be optimistic. The content stored on these physical materials are subject to local destruction; the entire Library of Alexandria went up in smoke after only 250 years in existence, even though the papyrus and vellum scrolls in it probably could have lasted much longer.

What is the best to store these historical treasures? My answer is threefold:


  1. digitize the material to mitigate physical degradation of the media over time
  2. relentlessly adapt the digital content to newer storage media as technology advances makes previous storage media obsolete
  3. physically disperse the content to mitigate the forces local destruction (purposeful or accidental)


So, besides the oral tradition of telling stories, the only real hope of keeping my family’s history alive is to digitize it, transform it from time-to-time and to disperse it.

Network Storage and Cloud Storage

Hard disk are mechanical machines. Their parts wear and then crash. It’s not a question of if, but only of when.  A solution to this issue is to set up a storage scheme where two or more hard disks have mirrored content. In that way, if one of them crashes, the other has a complete copy of all the information. Then, you just replace the defective hard-disk, and the set of content is copied across. Now you are back to steady-state again. I have set this system up in my house using a consumer device called DLink DNS-323. It is a little box connected to my network with a pair of hard disk in it. Software running on all the computers in the house continually copy important files from the local hard-drives over to the DNS-323. If a computer hard-drive were to crash, we could restore the content from the DNS-323 after replacing the hard-drive. Even if a file is mistakenly erased, we can get it back from the DNS-323.

But this isn’t just a disk-in-a-box. The DNS-323 is a dual-disk device.  If a disk in the DNS-323 were to crash, our back-up information wouldn’t be lost. That is because the other disk in the box has a perfect copy. I can simpley swap out the defective disk for a new disk and the content from the other disk will be automatically copied over.

D-Link-DNS-323Hard disk redundancy on the network

That’s a good step to preserving important family memories, but it doesn’t address the need to physically disperse content. Remember, everything in a building is at risk in a theft or fire, even dually-redundant hard-disks put in place by skilled geeks.

The current best practice in information storage is to put your content in the cloud. What this means in practice is that your content will reside on redundant and backed-up hard-disks connected to one or more servers somewhere in the USA. So, if your local copy of your content is damaged or destroyed, you can (in theory) simply download a copy from your cloud storage provider. Mind-you, all of this is contingent on keeping up your annual payments, having your provider stay in business throughout the years, and having the fabric of our society staying together so that services like these don’t end up like the Library of Alexandria. Admittedly, these are a lot of assumptions.  So, realists that I am, I consider the cloud to be a medium-term solution to the problem of content preservation.

There are plenty to choose from, but I ended up signing up with a service called Crash Plan.  I have set up my family computers so that they all copy important content to both the DND-323 and the Crash Plan servers in the cloud.

Crash PlanOnly 6 months to go before all my home videos are uploaded ….

You have to have some patience with this set up. The connection between our house and the Crash Plan servers (in Minnesota, they tell me) is through the family Internet DSL connection. With 400GBytes of video data queued to upload through only 400Kb/sec of upload bandwidth, this initial process is going to take over 6-months!

One thing about history is that it teaches us patience.

eBook? eGads!

Filed Under Tech

I don’t want to make too big a deal about it, but I got a Kindle for my birthday and I found the impact on me to be a little scary.

Unless you have been living under a rock, you will have noted that eReader devices and their associated eBooks are becoming quite popular. Over the last couple of years, they have emerged to become a significant element in the rapidly evolving cyborg that is modern western culture. The price had recently come down on the latest generation of these devices and thus I felt I was ready to satisfy my intellectual and geek curiosity. I let my wife know I would be interested in one. So, on the day of my birthday, she “gave” me the one I had chosen and ordered the week before.



Its a Book on a Screen. Get Over it.

So what? What’s the big deal?

Reading is important to me. I read not just for the decadent escapism of a good book; I read to satisfy my need to understand who I am and how the world works. It’s hard to describe, but I read for sort of the same reasons a bodybuilder works out … for the fitness it provides. I feel ‘flabby’ if I’m not reading — unfit intellectually and spiritually.

When I was in my teens, I read fantasy and science fiction books. Isaac Asimov, David Niven, Harry Harrison and JRR Tolkien were among my favorites . Then, in my early twenties, after reading Douglas Hofstadter’s amazing Godel, Escher, Bach , my appetite changed to a craving for psychology, natural history and sciences. As I read more on these topics, I followed references and reviews and I found myself increasingly gravitating to books written by the great thinkers of our time. I sought out authors who could explain nature and human-kind through writings in science, natural & human history and philosophy. Lately I begrudgingly find myself developing a taste for well written literature that explores elements of the human condition ( such as Neal Stephenson ).

What I have read over these years has significantly molded who I am and my perspectives on how the universe works. I have steadily collected a library of hundreds of books.  Scattered at home and in my office are the seminal works by Richard Dawkins, Roger Penrose, Steven J. Gould, John Keegan, Jared Diamond, Robert Wright and others. These works have shaped my understanding, have structured my thoughts and have helped to dispelled the fog of my ignorance.

Almost like a child with a security blanket, I have kept my books close to me all these years. I never borrowed books — I almost always bought them so that I could keep them. For example, I can lift my head up from this computer screen now and can see dozens of books (“my” books) on the shelves of the family room. There they sit stacked and scattered sedately on the shelf. Some have been with me for 35 years. Just glancing at them brings back into focus their key messages and the feeling of wonder I felt when I first read their pages. Once in a while, I pull one out read a passages to my sons when we are discussing a pertinent topic. Most of the time they just lay there quietly. But even so, it brings me a gentle pleasure knowing that I can walk over and take one down and once again be bathed in their knowledge.

LCD?  Thou Upstart!

So, how would a cold electronic slate stand-up to the majesty of the printed book? Was it silly to assume that a skinny, inorganic doodad would somehow matching the stately presence of a well bound codex? Was I just wasting my money on a fad? There is only one way to find out. I decided that I was going to give this a fair shot, but I secretly thought it going to be a short lived experiment.

First, it is important to say that Amazon has done a decent job with their latest generation eReader. Its design and functionality has a lot going for it and it is priced reasonably ($139). Many have written reviews on the Kindle hardware and user experience ( so I won’t). Suffice it to say that the reading experience is surprisingly good.

To ease my transition (and give the doohickey a fighting chance) I also ordered the nice leather cover with the integrated light. This addition nearly doubled the purchase price, but aesthetics are important. It made the glass and plastic device feel more like a ‘real’ book.

eBook in a Book's Clothing

Dr. Jekyll and Mr. eHyde

Soon after firing up the device and using it for a while, I noted a curious change in how I read.

I didn’t just buy an eBook at the eStore, download it onto the eReader and start reading linearly, as I did a regular book. Combined with the power of the public Internet, the Kindle gave me access to dozens of important books I was interested in, but would have never had taken the troubled to find or to buy. It is not well known, but the copyright on many books expire about 70 years after the author’s death. At that point, the intellectual property reverts to the public domain. That means there are no royalties to be paid and anyone can copy and publish the work.

Amazon provides a good number of these older public-domain books for download on their website for free or for a nominal amount (a dollar or two). But other brilliant projects such as, are taking on the job with a passion — digitizing huge libraries of older books and making them available for free download. The size and diversity of their catalog is stupefying. I have downloaded (for free!) seminal scientific and literary milestones including Darwin’s On the Origins of Species, Newton’s Principa Mathematica, the complete works of William Shakespeare, Fyodor Dostoyevsky’s Crime and Punishment, chunks of Encyclopedia Britannica, books of poetry by Robert Service, The Koran, etc. etc. Say what you will about the deleterious impact of the internet on our culture, Internet + Gutenberg Project + eReader = boon to literacy.

On the Kindle, you can search and annotate the eBook’s text. You can share you annotations using social media. You can pick-up reading where you left off on your PC or your Smart Phone (it syncs everything up). You can change font size. You can highlight an unfamiliar word and get a pop-up dictionary explanation in just one second. You’re not just passively reading, you’re busy doing stuff.

In three months, I’ve downloaded more than two dozen books (and several audio books to boot). However, having a book does not mean reading a book. Since early October, I have managed to read only five eBooks cover-to-cover (note the soon-to-be arcane reference to covers):

Einstein: His Life and Universe Walter Issacson
The Einstein Theory of Relativity H.A. Lorentz
Two Years Before the Mast Richard Henry Dana Jr.
The Road Cormac McCarthy
Anabasis Xenophon

I have started reading a dozen others (where ‘started’ is anything from ‘skimmed a few pages’ to ‘read a chapter or two’) .

That being said, it was easy to read the five books on the Kindle’s eInk screen. I didn’t suffer. I got as much out of them as I would have if I read them in paper form. I’m almost ashamed to admit that I liked it.

Now for the scary stuff. The Kindle has turned me into a distracted and impatient reader. Over the course of a few months, my reading has changed from a slow stroll down a leafy lane to a game of over-caffeinated hop-scotch. No more do I reach over to the bed table and select from a stack of 3 in-progress books, one of which I will advance a dozen or so pages before I drift off. Now, I grab my eReader, peruse the twenty or so eBooks I have downloaded and then jump into one for a little dip. If it is boring or I don’t get a buzz off one, I pop back up and then dive into another one. Shampoo, rinse, repeat.

Interested in reading a bit more of Benjamin Franklin’s autobiography? Hop in and scan a page or two. Are his musings too arcane?  No problem, let’s see what Darwin had to say about animal husbandry in 19th century England. The device remembers where you were and takes you back to the location you last left off. Had enough Victorian discourse on pigeon plumage deformation under artificial selection? Time for something a little more timely. Let’s check out the front page of the New York Times (yes, the Kindle has WIFI and a web browser built in). Etc. Etc.

Reading is no Longer A Spectator Sport

So what does this all mean?  What conclusions do I draw from the experiment? Is the eReader/eBook a good thing or a bad thing? It’s tough to say.

As Melvin Kranzberg said, technology is neither good nor bad; nor is it neutral.  In this case, Mr. Kranzberg is right on. eReaders and eBooks are not neutral. What they are doing is changing the nature of the medium.

With almost 10% of books sales now e-books, the marketplace for the written word is just starting to feel the change. Traditional media such as newspapers and magazines have struggled to try to monetize their content on the web now have found a possible channel for electronic distribution through eReader devices (eBook readers, general purpose devices such as iPads). Venerable brands like the New York Times and the Economist may yet survive the inexorable implosion of their print businesses.

It is not just the distribution channel for books that will undergo change, but the concept of a book as a static lump of text is also up for grabs. Neal Stephenson is in the midst of a fascinating experiment of writing a book as an on-line only serial novel. Together with Greg Bear, he is writing the core story with chapters released every month or so. Readers ‘subscribe’ to the book and download chapters as they are published. Specialized apps are available for all the major Smart Phones, pads and eBook readers.  But here is where it gets interesting. The authors are also producers in the sense that they are working with artists, film-makers, game designers and us, the end-readers, to create a rich interactive social-world where the story takes place.


Don't just sit there reading, get busy

This and other social-media based projects may be pioneering a change to the very concept of a book. We’re not in Kansas anymore, Toto.

It is trite to quote Marshall McLuhan famous aphorism, but the old man couldn’t have been more right. The medium is the message.

Old and Improved

Filed Under Tech

This week, I had an interesting exchange of emails with colleagues from the old days . We worked together on the Ontario Telepresence Project, a multi-disciplinary, multi-year, multi-million dollar research project in the area of Computer Supported Collaborative Work. The 3-year project pioneered the use of videoconferencing in group settings and explored the intersections of sociology and technology before way before it was fashionable to do so.

Gale Moore, who was a among the lead researchers on the project, started the conversation thread. She drew our attention to an article she just read about a ‘new’ group awareness system called myUnity.


MyUnity – dressed-up in all it’s newness

MyUnity is an awareness tool which presents you with an automatically updating visual contact list. It displays your buddy’s availability based on multiple sources of information about her. For example, it draws on the location of her cell phone and comparative snap-shots from her webcam.  From this (and other cues) it determines if your buddy is in and/or available. Pretty Cool.

Cool indeed.  However, it turns out that this idea has been around for quite a while. As a matter of fact, in 1997 a colleague and I built a product that did pretty much the same thing called Prorata.


ProRata circa 1997 – Ahhh, I was so handsome back then

Prorata grabbed a grainy, low-resolution, black & white snapshot from your buddy’s webcam about once in 15-seconds. It gathered a few of these together and displayed them in a kind of buddy-grid so that you could see roughly who was in, who was out and who was busy. We purposely didn’t grab real-time, high-res, colour images because we didn’t want this to be surveillance, but rather awareness. The social analogy was to make it like looking down a hallway and seeing someone seated at their desk. You see just enough to know their availability, nothing else.  We would know if the buddy was on the phone, sitting with a visitor, out of the office, etc.  Just like peeking into an office in real-life. And the best part is the you and your buddy’s didn’t have to explicitly set a flag to tell people your availability from moment to moment. We could infer this simply by glancing at the grid and seeing what you were doing. Chat and click-to-call features were also part of the application.

Now, Prorata was ahead of it’s time (a euphemism meaning I didn’t sell many copies). However, I like to think that it anticipated many of the group awareness/collaboration tools that followed.

It would be nice to say that this buddy-grid concept was my original idea, but it wasn’t. No — the concept was around and I ‘borrowed’ the idea from a tool called Postcards cooked up at the University of Toronto. Postcards also grabbed webcam images and displayed them on a grid. But it also took as one of it’s inputs the ‘door state’. Using the roller-ball mechanism of a regular PC mouse,  the researchers instrumented the hinges of our office doors so that the software could sense if our doors were open, ajar or closed.  These are important social signals and now we could use our doors as inputs to our PCs.  Nice!

Door Mouse

A rubber-band and a torn-apart PC mouse = door state sensor

However, the UofToronto’s Postcards application was itself based on still earlier work by Paul Dourish and Sara Bly called Portholes (see the Proceedings of the ACM CHI ’92 Conference pages 541-547). This tool also did the buddy-grid thing.

But wait — you guessed it, Portholes was itself based on even earlier work by Travers and Borning who presented on it at a 1991 ACM CHI conference on Human Factors in Software. I am sure the trail doesn’t end there…

Anyway,  as imitation is the sincerest form of flattery, Gale was bemused at the apparent novelty of the myUnity product. The implied question is: can a product really claim to be ‘new’ if it basically the same idea that was cooked up twenty years ago?

The answer is interesting.

Bill Buxton (who was our Principal Researcher on the project) responded to Gale’s email by pointing to a magazine article he wrote in which he ponders this particular innovation phenomenon.  In the article, he refers to the muti-decade incubation period for ideas as “The Long Nose of Innovation”. The nose being the stretched-out period of time before the adoption curve starts to take off.   Bill observes that it takes a very long time for a technological idea to spin and morph and grow into a mainstream product/service.  He points to a research study that traced the history of a set of core technologies in the CIT sector. The study found that it is not at all uncommon for a technology to take 20 or 30 years to mature from inception to a $ billion industry. Bill ends the thought-provoking article with this observation: “Any technology that is going to have significant impact over the next 10 years is already at least 10 years old“.

So, the take away message for me from our email conversation is that the game of innovation is not just about invention. Truly new stuff is important, but it’s not the whole story. Innovation is also about how you bring forward technologies that may already be invented, but in need of interconnection and clever transformation.

The technologies for the next $ billion dollar marketplace are likely close at hand.

To see a world in a grain of sand

Filed Under Tech

I had a moment of awe during these ‘days of awe’ … but not the religious kind.

When I was a grad student at the Technion in the mid 80s, I designed a custom image processor on a microchip whose transistor channels were about 5 micrometers wide ( 5 x 10 ^-6   = 5  millionths of a meter). With this technology, I could line up about 15 transistors end-to-end across the width of a human hair. That seems as impressive to me now as it did then.

However a few days ago, I read a story about Intel’s recent announcement that it’s upcoming generation of processors will have transistors 32 nanometes wide, with a roadmap taking them to 22 and then 15 nanometers in just a couple of years. Fifteen nanometers is 15 billionths of a meter. That’s almost a thousand times smaller than the technology I was working with twenty years ago.

With Intel’s new fabrication technology, I could have lined up over 5,300 transistors end-to-end across the width of a human hair. In fact, fifteen nanometers is so small, that I would have had to take into consideration that I would only get about 60 atoms of silicon to work with in the transistor channel. Quantum effects start to make themselves felt at this scale.  I would have paid more attention in my quantum physics classes had I known that in only a few decades designers would bouncing electrons off of only a few dozen slippery atoms.

What gave me pause when I read the article was not just that the advanced fabrication technology I used for my Master’s degree had been eclipsed a thousand-fold. What I marveled at was the market pull for these ever-shrinking devices. To me, it is a complete surprise use that these ultra small, ultra cheep devices are now being used for. No one a few decades ago would dream that homes would have dozens of high-power processors in them and that middle-class teenagers would walk around with a half dozen powerful computers for their personal use (laptops, cell phones, music players, smart-chip credit cards, etc.). Today, my teen-aged kids would find it difficult to keep up their studies, their hobbies and their friendships without using personal processors and the computer networks that link them. In an incredibly short time, western economies and society have quickly adopted and become dependent on cheap CPUs, memory and networks.

In their book Connected , Nicholas Christakis and James Fowler coin an apt term for the species who’s behaviour is mediated by social connections — Homo dictyous — “network man” (from the Latin Homo for “human” and the Greek Dicty for “net”) . They use this idea in a slightly different context (as an alternative to economic-based analysis of human behaviour), but I think the term is apt in a more technological sense. We have become deeply dependent on our silicon devices in ways that we don’t even fully understand.

With Moore’s law , we can look forward to even smaller devices by the end of the decade. In fact, fifteen nanometers is just an order of magnitude larger than the size of a DNA molecule (about 2nm). So, it is not unreasonable to expect that transistors will be the size of DNA by 2020. They will also be extremely cheap, extremely low-power and extremely ubiquitous.

Imagine the possibilities.

Addendum: Things keep driving forward. In the 6-weeks since I wrote this blog. On Oct 29, 2010, Intel, Samsung, Toshiba announced a consortium aiming for 10nm chips by 2016.

Non-Business Books About Business

Filed Under Tech

You can tell a lot about people by what they collect. For instance, when I was a teen, one of the ways that I would learn about the party host was to rummage through their stack of LPs. It said something about the guy’s personality if he had B.B.King and Hendrix albums on the top of the pile, vs. Donovan and K.C. and the Sunshine Band.

As I got older, I would look through the books on the shelf. Dozens of heavily thumbed sci-fi pocket-books paints a different picture of personality than does 1000-page romantic epics (like The Thornbirds) stacked like bricks next to the bed.

Even in today’s electronic world, books remain an interesting indicator of personality. Business books are among the standard fixtures on the credenza of many of the business executives I know. The giant lettering screaming at you from the glossy dust-covers seem to be the sine qua non of the mahogany set. Often, my executive colleagues are sporting the latest just-off-the-press hardcover by the guru of the moment. Smiling at us from the back-page vanity photo, these authors extol us that our mission is in REENGINEERING THE CORPORATION, but we have to take on the SEVEN HABITS OF HIGHLY EFFECTIVE PEOPLE as go IN SEARCH OF EXCELLENCE but to be careful about CROSSING THE CHASM or else we may reach the TIPPING POINT.

The Cream of the Business Press?

I read many of these kinds of popular business press books while I was studying for my MBA. As my studies were part-time and took 5-years to complete, I saw more than a few ideas come and go. New theories would contradict (or at least displace) the old ones. Firms that were highlighted for their ‘excellence’ were a few years later bankrupt and out of business. Authors which were lauded on talk shows for their brilliant insight were soon in the shadows of obscurity. Few of the ideas stood the test of time. I am not saying that their is nothing to learn from those that study the nature of economics and commerce. But the track-record of the popular business press is poor.

Ten Excellent Books

Some Non-Business Books on Business

I am a technology executive and I too do a lot of reading about business. However, I rarely read business books. In fact, I believe some of the best ideas on the subject is in the realm of evolutionary science, psychology and in human history. In my reading of evolution (through such brilliant authors as Richard Dawkins, Robert Wright and Jonathan Weiner) I have learned about game theory, competition/collaboration, the interplay of genotype/phenotype, envorionmental fit, adaptation and human psychology. Douglas Hofstadter, Roger Penrose and Steven Pinker have taught me about the fundamental building blocks of the mind and how they form culture, morals, behaviours and norms. Through my study of conflict and military history (by such authors as John Keegan, Sun Tzu, Anthony Beavor) and the history of innovation/trade/economics (by Daniel Boorstin, Mark Kurlansky, Pierre Burton) reveal the manifestation of our evolutionary and psychological makeup in the interplay of leadership, technology, passion, risk taking and the pursuit of security, status and wealth.

The ideas in these books speak to the fundamental nature of who we are, how we interact with one another and the ways we can make our living in the world. Isn’t that what business is all about?

Inputs and Outputs

Filed Under Tech

I am ‘tech support’ for my parents and in-laws. Whenever I travel to Winnipeg to visit them, I spend hours installing drivers, purging spam, defragmenting disks, installing printers and memory, etc. etc. 

During my last visit, my mother-in-law was telling me something about her ‘computer’. It took me a moment but then I realized she was actually talking about her CRT monitor. To her,  the monitor was the computer. That is because that is the part that she looks at. The glowing screen is where she receives feedback on her keyboard and mouse inputs and see the resulting outputs. She doesn’t interact with the grey box full of boards, wires and spinning disks — it is irrelevant to what she is trying to accomplish. To her (as to many people) the input/output transducers are the computer.

My mother-in-law’s cognitive model of computing brought to mind a time in the 90’s where I worked with a group of user-interface geniuses at the University of Toronto.  I was a research manager funding and promoting the work of professors, students and staff working on multi-disciplinary projects within the departments of computer science, engineering, sociology and psychology.  These folks were creating the intellectual framework for many of the user interfaces that we use today.

I worked closely with a team that was on the forefront of what was then called Computer Supported Collaborative Work.  The Ontario Telepresence Project  built and experimented with numerous computing, audio and video systems to enable collaboration at a distance. It was there, years before the Internet became part of our society’s fabric, that I learned about distance collaboration through videoconferencing and computing systems.

Another one of my favourite groups were the Neural Networks guys.  This eclectic bunch were exploring how to create dynamic, adaptive computing systems which simulated how our brains learn.  Their research accomplishments were many, but among the most evocative for me was student Sidney Fels’ Glove Talk II.

Sidney Fels' Glove Talk II

Listen to the Hand (click for 30-second movie)

In Sidney’s own words:

GloveTalkII is a system that translates hand gestures to speech through an adaptive interface. Hand gestures are mapped continuously to ten control parameters of a parallel formant speech synthesizer. The mapping allows the hand to act as an artificial vocal tract that produces speech in real time. This gives an unlimited vocabulary in addition to direct control of fundamental frequency and volume. Currently, the best version of Glove-TalkII uses several input devices (including a Cyberglove, a ContactGlove, a three space tracker, and a foot pedal), a parallel formant speech synthesizer, and three neural networks. One subject has trained to speak intelligibly with Glove-TalkII. He speaks slowly but with far more natural sounding pitch variations than a text-to-speech syntesizer. 

It is incredible to think that this ground-breaking work was done 15-years ago and only now are gesture-based inputs finding their way into the marketplace.  Apple’s iPod with it’s gesture control is only the most famous example of many new products in this field.

I believe that increased processor speeds, miniturization and mobilitiy are important factors in bringing the benefits of information technology to our society.  But we will also need innovative, adaptive, intuitive user-interfaces which fit the way we work and interact.
