Playing with emergence is like gardening

It’s been a while since I fin­ished read­ing Steven Berlin John­son’s Emer­gence. I picked up the book because ever since I start­ed think­ing about what IxDs can learn from game design, the con­cept of emer­gence kept pop­ping up.

Johnson’s book is a pleas­ant read, an easy-going intro­duc­tion to the sub­ject. I start­ed and fin­ished it over the course of a week­end. There were a few pas­sages I marked as I went a long, and I’d like to quote them here and com­ment on them. In order, they are about:

  1. Prin­ci­ples that are required for emer­gence to hap­pen
  2. How learn­ing can be uncon­scious
  3. Unique skills of game play­ers
  4. Gar­den­ing as a metaphor for using (and mak­ing) emer­gent sys­tems

A cheat sheet

Let’s start with the prin­ci­ples.1

If you’re build­ing a sys­tem designed to learn from the ground lev­el, a sys­tem where macroin­tel­li­gence and adapt­abil­i­ty derive from local knowl­edge, there are five fun­da­men­tal prin­ci­ples you need to fol­low.”

These prin­ci­ples togeth­er form a use­ful crib sheet for design­ers work­ing on social soft­ware, MMOGs, etc. I’ll sum­marise each of Johnson’s prin­ci­ples here.

More is dif­fer­ent.”

You need to have a size­able amount of low-lev­el ele­ments inter­act­ing to get pat­terns emerg­ing. Also, there is a dif­fer­ence between the behav­iour you will observe on the microlev­el, and on the macrolev­el. You need to be aware of both.

Igno­rance is use­ful.”

The sim­ple ele­ments don’t have to be aware of the high­er-lev­el order. In fact, it’s best if they aren’t. Oth­er­wise nasty feed­back-loops might come into being.

Encour­age ran­dom encoun­ters.”

You need chance hap­pen­ings for the sys­tem to be able to learn and adapt.2

Look for pat­terns in the signs.”

Sim­ply put, the basic ele­ments can have a sim­ple vocab­u­lary, but should be able to recog­nise pat­terns. So although you might be work­ing with only one sig­nal, things such as fre­quen­cy and inten­si­ty should be used to make a range of mean­ings.

Pay atten­tion to your neigh­bours.”

There must be as much inter­ac­tion between the com­po­nents as pos­si­ble. They should be made con­stant­ly aware of each oth­er.

Now with these prin­ci­ples in mind look at sys­tems that suc­cess­ful­ly lever­age col­lec­tive intel­li­gence. Look at Flickr for instance. They are all present.

Chicken pox

I liked the fol­low­ing pas­sage because it seems to offer a nice metaphor for what I think is the unique kind of learn­ing that hap­pens while play­ing. In a way, games and toys are like chick­en pox.3

[…] learn­ing is not always con­tin­gent on con­scious­ness. […] Most of us have devel­oped immu­ni­ty to the vari­cel­la-zoster virus—also known as chick­en pox—based on our expo­sure to it ear­ly in child­hood. The immu­ni­ty is a learn­ing process: the anti­bod­ies of our immune sys­tem learn to neu­tral­ize the anti­gens of the virus, and they remem­ber those neu­tral­iza­tion strate­gies for the rest of our lives. […] Those anti­bod­ies func­tion as a “recog­ni­tion sys­tem,” in Ger­ald Edelman’s phrase, suc­cess­ful­ly attack­ing the virus and stor­ing the infor­ma­tion about it, then recall­ing that infor­ma­tion the next time the virus comes across the radar. […] the recog­ni­tion unfolds pure­ly on a cel­lu­lar lev­el: we are not aware of the vari­cel­la-zoster virus in any sense of the word, […] The body learns with­out con­scious­ness, and so do cities, because learn­ing is not just about being aware of infor­ma­tion; it’s also about stor­ing infor­ma­tion and know­ing where to find it. […] It’s about alter­ing a system’s behav­iour in response to those pat­terns in ways that make the sys­tem more suc­cess­ful at what­ev­er goal it’s pur­su­ing. The sys­tem need not be con­scious to be capa­ble of that kind of learn­ing.

Empha­sis on the last sen­tence mine, by the way.


John­son writes about his impres­sion of chil­dren play­ing video games:4

[…] they are more tol­er­ant of being out of con­trol, more tol­er­ant of that explorato­ry phase where the rules don’t all make sense, and where few goals have been clear­ly defined.”

This atti­tude is very valu­able in today’s increas­ing­ly com­plex world. It should be fos­tered and lever­aged in areas besides gam­ing too, IMHO. This point was at the core of my Play­ing With Com­plex­i­ty talk.


Inter­act­ing with emer­gent soft­ware is already more like grow­ing a gar­den than dri­ving a car or read­ing a book.”5

Yet, we still tend to approach the design of sys­tems like this from a tra­di­tion of mak­ing tools (cars) or media (books). I not only believe that the use of sys­tems like this is like gar­den­ing, but also their cre­ation. Per­haps they lie in each other’s exten­sion, are part of one nev­er-end­ing cycle? In any case, when design­ing com­plex sys­tems, you need to work with it “live”. Plant some seeds, observe, prune, weed, plant some more, etc.

I am going to keep a gar­den (on my bal­cony). I’m pret­ty sure that will teach me more about inter­ac­tion design than build­ing cars or writ­ing books.

Playing With Complexity — slides and notes for my NLGD Festival of Games talk

When the NLGD Foun­da­tion invit­ed me to speak at their anu­al Fes­ti­val of Games I asked them what they would like me to dis­cuss. “Any­thing you like,” was what they said, essen­tial­ly. I decid­ed to sub­mit an abstract deal­ing with data visu­al­iza­tion. I had been pay­ing more and more atten­tion to this field, but was unsuc­cess­ful in relat­ing it the oth­er themes run­ning through my work, most notably play. So I thought I’d force myself to tack­le this issue by promis­ing to speak about it. Often a good strat­e­gy, I’ve found. If it worked out this time I leave for you to judge.

In brief, in the pre­sen­ta­tion I argue two things: one — that the more sophis­ti­cat­ed appli­ca­tions of inter­ac­tive data visu­al­iza­tion resem­ble games and toys in many ways, and two — that game design can con­tribute to the solu­tions to sev­er­al design issues I have detect­ed in the field of data visu­al­iza­tion.

Below are the notes for the talk, slight­ly edit­ed, and with ref­er­ences includ­ed. The full deck of slides, which includes cred­its for all the images used, is up on SlideShare.

Hel­lo every­one, my name is Kars Alfrink. I am a Dutch inter­ac­tion design­er and I work free­lance. At the moment I work in Copen­hagen, but pret­ty soon I will be back here in Utrecht, my love­ly home­town.

In my work I focus on three areas: mobil­i­ty, social inter­ac­tions, and play. Here is an exam­ple of my work: These are sto­ry­boards that explore pos­si­ble appli­ca­tions of mul­ti­touch tech­nol­o­gy in a gat­ed com­mu­ni­ty. Using these tech­nolo­gies I tried to com­pen­sate for the neg­a­tive effects a gat­ed com­mu­ni­ty has on the build-up of social cap­i­tal. I also tried to bal­ance ‘being-in-the-screen’ with ‘being-in-the-world’ — mul­ti­touch tech­nolo­gies tend to be very atten­tion-absorb­ing, but in built envi­ron­ments this is often not desir­able.1

I am not going to talk about mul­ti­touch though. Today’s top­ic is data visu­al­iza­tion and what oppor­tu­ni­ties there are for game design­ers in that field. My talk is rough­ly divid­ed in three parts. First, I will briefly describe what I think data visu­al­iza­tion is. Next, I will look at some appli­ca­tions beyond the very obvi­ous. Third and last, I will dis­cuss some design issues involved with data visu­al­iza­tion. For each of these issues, I will show how game design can con­tribute.

Right, let’s get start­ed.

Learning about emergence from games

A game of Go

I’m still try­ing to get a grip on why I think games are such a good ref­er­ence point for IAs and IxDs. I’ll try to take anoth­er stab at it in this post. Pre­vi­ous­ly I wrote about how games might be a good way to ‘sell’ algo­rith­mic archi­tec­tures to your client. Even if you’re not active­ly push­ing your clients to adopt ideas such as on-the-fly cre­ation of site nav­i­ga­tion, soon­er or lat­er I’m con­vinced you’ll find your­self con­front­ed with a project where you’re not asked to devel­op a defin­i­tive infor­ma­tion archi­tec­ture. Instead you’ll be charged with the task to come up with mech­a­nisms to gen­er­ate these pro­ce­du­ral­ly. When this is this case, you’re tru­ly fac­ing a sec­ond-order design prob­lem. How can games help here?

One of the defin­ing char­ac­ter­is­tics of games are their com­plex­i­ty. A few years ago Ben Cer­ve­ny gave a bril­liant talk on play (MP3) at Reboot 7.0 and men­tioned this specif­i­cal­ly — that much of the plea­sure derived from game-play is the result of the play­er com­ing to terms with com­plex pat­terns. This com­plex­i­ty is some­thing dif­fer­ent from pure ran­dom­ness and most cer­tain­ly dif­fer­ent from a ‘mere’ state machine. In oth­er words, games show emer­gence.

There are many exam­ples of emer­gent sys­tems. The Game of Life springs to mind. This sys­tem isn’t real­ly a game but shows a remark­able rich­ness in pat­terns, despite (or maybe because of) the fact that it is based on a set of decep­tive­ly sim­ple rules (which appar­ent­ly took its cre­ator, John Con­way, over 2 years to per­fect!) The thing is though, The Game of Life is not inter­ac­tive.

A won­der­ful exam­ple of a com­plex emer­gent sys­tem that is inter­ac­tive is the real game Go. It has a set of very sim­ple rules, but play­ing it well takes a huge amount of prac­tice. The joy of play­ing Go for me (an absolute begin­ner) is large­ly due to dis­cov­er­ing the many dif­fer­ent per­mu­ta­tions play can go through.

So get­ting back to my ear­li­er remark: If you’re con­vinced you’ll need to get a bet­ter han­dle on solv­ing the sec­ond-order design prob­lems pre­sent­ed by the design of com­plex emer­gent sys­tems, games are an excel­lent place to start learn­ing. They are emer­gent first and inter­ac­tive sec­ond, the per­fect twin to the web envi­ron­ments we’ll be shap­ing in the future.
