Stanford Virtual Worlds Research

This article contains selected notes on the some of the research conducted at Stanford University on virtual worlds and the interaction of humans within virtual environments. It is based on sessions held during the Media X conference. Pat Hanrahan defined a virtual world as a “networked multi-user distributed environment”. But the audience reaction was altogether less technical, and more oriented towards the social implications of such environments.

Stanford is one of the few universities that can not simply be accused of climbing on the virtual worlds band-wagon: People like Nick Yee were examining these environments at long before they were regarded as a suitable topic for serious research. Related sessions on workplace application and DKP and the archiving of virtual worlds/games will be covered by separate articles.

Why Use Virtual Environments for Medical Training?

LeRoy Heinrichs spoke on the use of virtual medical rooms for training medical students.

It is cost effective, even when developing bespoke software: Conducting a live training exercise in a physical hospital costs about $50,000 per day, and can only train a relatively small group. Stanford’s first virtual patient model cost almost $1 million to develop, yet in the long run is still cheaper than physical-world exercises.

Initial analysis of performance is not yet conclusive, however early signs suggest knowledge does transfer to real practice, and virtual training is just as good as other methods.

The business case for virtual worlds is ultimately a critical driver to their success outside of their traditional (game or social) environments. Medicine is a fundamentally expensive business, so even with custom software, one user can make a saving. Other sectors may be slower to follow, waiting for the cost to drop. Cost are likely to drop by sharing development costs between multiple projects - either industry-wide initiatives, or through the development of platforms for virtual worlds, which will transfer most of the costs on to a single provider, who can then share those costs between many customers.

Size Matters

Renate Fruchter revealed that visual size does matter. Ideally people should appear on screen life-size: In most cases that means a bigger screen!

Jeremy Bailenson outlined some of Nick Yee’s research behind the “virtual mirror”. The virtual mirror is a technique that changes the visual identity of a person’s avatar while in a virtual world: Their avatars literally look into a mirror and take a different form.

The experiment is useful in understanding the consequences of an apparently fluid online identity, and determining whether self-perception theory (and similar) transfer to avatars: If you don’t know how to act, you look at yourself, particularly your uniform, and that determines your behaviour.

Height is important. In the physical world, height correlates to confidence and personal income. Through the use of an “ultimatum game”, where avatars negotiate a deal, it was possible to show that a 10cm difference in avatar height increased the value of that avatar’s deals in their favour.

Physical attractiveness of avatars was also tested by examining “interpersonal distance”: If you like someone, you will tend to stand closer to them. And they’ll disclose more information.

Finally the effects of age were tested by morphing pictures of one’s self to show the passing of years. The older the avatar, the more the subjects were prepared to invest in their retirement.

Virtual Policy and Law - Edinburgh Digital Interactive Symposium

The first Edinburgh Digital Interactive Symposium was held on 15 August 2007. It aimed to bring together academics and the “games” industry, to discuss topics from games industry innovation to policy in virtual worlds. The diversity of people these topics attracted was remarkable - from philosophers to corporate executives. It should come as no surprise that we all struggled to understand each other. Yet this was a group who merely by expressing their interest in such an event, tend towards curiosity.

This is the first set of notes from the Edinburgh Digital Interactive Symposium, covering virtual policy and legal issues. A second set of notes discusses innovation in the video games industry. These notes are my personal interpretation of what was discussed, not a transcript of the event.

Law

The lawyers are very excited about virtual worlds. Antonis Patrikios, from Field Fisher Waterhouse LLP, was speaking. At the most basic level, it’s a clean slate with no case law, yet almost endless contentious issues. You can almost see the dollar signs in their eyes. At one extreme there is a school of thought that wants to declare a new thread of international law - that is, to treat virtual environments as separate legal jurisdictions. At the other, the simple statement that real world objectives (and therefore regulation and law) will be directly applied to virtual worlds, without special consideration.

An example of one of the many crunch-points: If by “playing” I generate money-tokens (i.e., not necessarily legal currency, but having the same effect within the world they are generated), and someone does something that scams me of those money-tokens, do I have any rights in (physical) criminal law? If prior to bankruptcy, I move all my assets into a virtual currency, can the authorities recover them? One position is that I only have rights if the operators of the virtual environment allow me to legitimately transfer my money-tokens into real money. But it could be argued that if something is perceived as having value, it has value, even if it can’t be directly or legally (contractual law) monetarized.

Now, add to the equation the fact that the representation of the person within the virtual environment may not be traceable to a real legal entity. (There’s a major philosophical argument here too, that I’ll step over because I don’t understand it - although I’m told the fact I don’t understand it is fundamental to my ability to try - er, yes.) The one entity that always is traceable is the operator of the world - who of course have no legal structure themselves, since they are typically a business and not a civil authority. The anonymity issues may be solved technologically, but the very possibility that operators might get dragged into criminal cases triggered by what their users do, is pretty frightening.

The role of physical location of operators, technology (servers), and users gets even more complex than in the (already arguably broken) website/e-commerce model. Does intellectual property of things created in these worlds transfer to the user? Trademarks are defined territorially, yet where is this virtual territory? And is a virtual re-creation the same as a real product anyway? There are big US/EU differences here. For example, in the EU it is far harder to patent the implementation of an idea, rather than the idea itself. So a lot of software patents that exist in the US, don’t exist in the EU, since software is commonly just the technical implementation of an idea.

There’s an interesting aside here on when money becomes a currency, and when a game becomes a bank. In the UK, if you offer credit, you’ll drift into financial regulation. The question nobody can answer is when that provision gets so large it becomes a bank, or so popular it threatens an existing currency.

Policy

Chris Francis (IBM) attempted a basic differentiation between virtual games/worlds. He takes more of a policy perspective than others. You have to be able to quantify each virtual experience on a spectrum, otherwise everything from simple online games to open real-currency trading platforms will be seen as the same thing in any regulatory debate. There are four factors, each of which covers a spectrum of topics. Generally the further to the left you are, the more like a game (and hence the most likely to avoid regulation), the further to the right, the more like real life (and so the more likely to be regulated):

Economy/tradability: In-game “gold” <<—>> Real money.
Identity/communication: Text <<–> Voice <–>> Accountability.
Plot: Scripted <<—>> Freeform.
Data flow: Augmented virtuality <<—>> Augmented reality.

Augmented virtuality I didn’t quite understand as a concept, but I’d interpret it as the re-creation of augmented reality concepts into an inherently virtual setting, rather than a real-world one. The interesting current topic is voice. Voice is a significant shift into the realm of communications legislation, since voice is widely understood to be communication, while text is a grey area. It follows that in introducing voice clients within games, game operators are more likely to open themselves up to regulation. I don’t think the games industry had considered that.

William Garrood spoke from Ofcom, the UK communications regulator. In the EU, active regulation is currently focused on television-like services, particularly using the radio spectrum for transmission. Electronic Communication Services legislation first appeared in 1998, passed into EU law in 2000, and has slowly been added to law across EU states. (It is worth noting that the regulatory cycle is almost 10 years, the academic cycle for studying it all is 3 years, yet 6 months is a typical industry timescale to deploying new technology in the arena.) The current legislation could allow virtual worlds to be regulated, at least in part - but nobody is yet. This was intentional in the design of the legislation: The EU agenda is to move away from regulation - there is a desire to try and foster self-regulation.

The EU may be regarded as a lower-risk environment than the US, simply because the US has no apparent boundaries - yet a litigious culture that will make discovering those boundaries expensive, and arguably will resolve them in favour of the dominant industry. The EU has a structure that is likely to “step in” if it looks like everything is going to hell in a handcart.

Ofcom is quite focused on the BBC’s traditional territory: Supporting “socially valuable content” in virtual environments. They already have a strategy called the Public Service Publisher. They’re aware that young audiences, in particular, are moving away from television, and are looking to fill the “post-TV gap”. It’s positive regulation, although how it works in practice is unseen.

Thoughts on a Socio-Economic Environment based on Nothing

One of the first economists to seriously examine virtual worlds (Edward Castronova) makes the observation that scarcity is fundamental to the environments that thrive. Utopia is boring. That’s a common theme of a lot of subsequent academic studies: The underlying patterns of human behaviour and motivation don’t fundamentally change from the physical to the virtual.

We have to “exist” in the real world (”eat, drink, breath”). We are highly likely to continue to “live” in it too (that is, perform social/economic/spiritual functions, in addition to biological existence). But it is not necessary to rely on it quite as much as we do now. Critically, living in virtual environments opens up some avenues for society’s development that may otherwise close.

Start at the “peak oil“-type resource analysis. The idea that up to this point, western culture (in particular) has assumed increasingly easy extraction of resources, but from this point forward will have to start dealing with the implications of increasingly hard extraction of resources. It follows that any “standard of living” (social status, economic income, etc) that is based on rampant consumerism and resource use, is likely to become highly unstable.

The fact that telecommunications and computerised technology is generally much more resource efficient than physical networks and products is almost a secondary consideration. The most interesting thing for me, is the creation of a sustainable socio-economic environment largely based on nothing.

That statement sounds like nonsense. But it has already mostly happened in highly developed western economies. Some examples:

So the most advanced types of work (which are also the ones generating a disproportionate amount of wealth), and the crude capitalist motivations of most western societies (the accumulation of stuff we don’t need) are already mostly based on “nothing”. It isn’t such a quantum leap to move those processes into a virtual environment.

We will never leave behind the physical world. But consider that once almost everyone in western society worked in agriculture, and now a tiny proportion do. There has always been a logical progression of society’s development which have led to progressively fewer people working in older sectors of the economy. This may simply be the next iteration. We are unlikely to understand it any better than an 18th century agricultural worker being shown a steam engine. As Charlie Stross’s Unpacking the Zeitgeist demonstrates, the present would be hard for us to have understood 30 year ago. Indeed, his description of the present is still a mystery to most of those living now.

But “our” children seem to embrace it. Many of the kid’s virtual worlds (such as Gaia Online) allow their young customers to buy virtual collectables using real money - these items don’t physical exist, but still represent something “of value”. These are not geeky male niches. Barbie Girls gained 3 million online users in its first two months - which from a discrete market of US teenage girls, probably numbering less than 20 million in total, is impressive.

There is still a big gap between making trivially small payments for virtual goods on glorified online social gaming/networking platforms, and the integration of these concepts into mainstream society and economy. However, these children are now developing some of their life skills in these virtual environments. Perhaps they will naturally accept what we will struggle to comprehend?

This topic evidently requires a lot more research and consideration. I’ve posted it here as a record of my current thinking only.
