Summary So Far

This entry is part 11 in the series An Opus to AR

In summary, Mobile AR has many paths leading to it. It is this convergence of various paths that makes a true historical appraisal of this technology difficult to achieve. However, I have highlighted facets of its contributing technologies that assist in the developing picture of the implications that Mobile AR has in store. A hybridisation of a number of different technologies, Mobile AR embodies the most gainful properties of its three core technologies: This analyst sees Mobile AR as a logical progression from VR, but recognises its ideological rather than technological founding. The hardware basis of Mobile AR stems from current mobile telephony trends that exploit the growing capabilities of Smartphone devices. The VR philosophy and the mobile technology are fused through the Internet, the means for enabling context-based, live-updating content, and housing databases of developer-built and user-generated digital objects and elements, whilst connecting users across the world.

I have shown that where the interest in VR technologies dwindled due to its limited real-world applicability, Mobile Internet also lacks in comparison to Mobile AR and its massive scope for intuitive, immersive and realistic interpretations of digital information. Wearable AR computing shares VR’s weaknesses, despite keeping the user firmly grounded in physical reality. Mobile AR offers a solution that places the power of these complex systems into a mobile telephone: the ubiquitous technology of our generation. This new platform solves several problems at once, most importantly for AR developers and interested Blue-chip parties, market readiness. Developing for Mobile AR is simply the commercially sensible thing to do, since the related industries are already making the changes required for its mass-distribution.

Like most nascent technologies, AR’s success depends on its commercial viability and financial investment, thus most sensible commercial developers of AR technologies are working on projects for the entertainment and advertising industries, where their efforts can be rewarded quickly. These small-scale projects are often simple in concept, easily grasped and thus not easily forgotten. I claim here that the first Mobile AR releases will generate early interest in the technology and entertainment markets, with the effect that press reportage and word-of-mouth behaviour assist Mobile AR’s uptake. I must be careful with my claims here however, since there is no empirical evidence to suggest that this will occur for Mobile AR. Looking at the emergence of previous technologies, however, the Internet and mobile telephony grew rapidly and to massive commercial success thanks to some strong business models and advancements in their own supporting technologies. It is strongly hoped by developers like Gameware and T-Immersion that Mobile AR can enjoy this same rapid lift-off. Both technologies gained prominence once visible in the markets thanks to a market segment called early adopters. This important group gathers their information from specialist magazine sources and word of mouth. Mobile AR developers would do well to recognise the power of this group, perhaps by offering shareware versions of their AR software that encourage a form of viral transmission that exploit text messaging.

Gameware have an interesting technique for the dissemination of their HARVEE software. They share a business interest with a Bluetooth technology firm, which has donated a prototype product the Bluetooth Push Box, which scans for local mobile devices and automatically sends files to users in acceptance. Gameware’s Push Box sends their latest demo to all visitors to their Cambridge office. This same technology could be placed in public places or commercial spaces to offer localised AR advertising, interactive tourist information, or 3D restaurant menus, perhaps.

Gameware, through its Nokia projects and HARVEE development program is well placed to gain exposure on the back of a market which is set to explode as mobile offerings become commercially viable, ‘social’, powerful, multipurpose and newsworthy. Projects like HARVEE are especially interesting in terms of their wide applicability and mass-market appeal. It is its potential as a revolutionary new medium that inspires this very series.

Constructing A Methodology

This entry is part 6 in the series An Opus to AR

Mobile AR is still highly prototypical, and has not received much previous academic attention thus far. A deep analysis of this technology and its implications requires a specially developed methodology, a methodology which acknowledges the pre-release status of the technology, and recognises that Mobile AR represents a fusion of a number of different media technologies. Given that there is no fixed point of entry for analysis, I look to academics writing on the subject of other radical and emergent technologies that (at the time of publishing) were yet to reach the mainstream.

At this early stage of the product cycle there is an interesting interplay between fields. This interplay is assessed in Digital Play: The Interaction of Technology, Culture, and Marketing by Kline et al. (2003), and it raises some arguments useful to the further analysis of Mobile AR as a cultural artefact. One of its lessons is that assessing new technologies is fraught with a long-standing academic and cultural issue: the problem of technological determinism. The theory is that new technologies drive social, political and cultural changes, and that the perceived linearity of technical progression is somehow representative of humanity’s own progression, parallel trajectories dependent on the other’s existence. The weaknesses arise when one assigns these same values to their own assessments, which isolate the subject technology from its wider context. Indeed, it is often forgotten that in order to achieve these innovations, social, economic, political and cultural forces have all worked in collusion. Digital Play (Kline et al., 2003), quotes Leiss (1990) in an especially provoking summarisation:

“Strictly speaking, there are no imperatives in technology. The chief mistake … is to isolate one aspect (technology) of a dense network of social interactions, to consider it in abstraction from all the rest, and then relate it back to that network as an allegedly independent actor.”

Leiss (1990: 2) in Kline et al. (2003:8)

Leiss’ point is that academic enquiry should seek to observe its subjects in the light of their true context. He highlights the importance of the “network” as the source of each technology, denying the idea that modern culture is ‘Under Technology’s Thumb’ (Leiss, 1990). A personal observation is that within the “network” also lie the forerunning technologies that gave rise to the newest developments, and the means to develop them further. This idea recalls McLuhan, who to the detriment of Leiss’ argument, was sometimes known as “the most famous media technological determinist” (Straubhaar & LaRose, 2005: 51) who, in reference to man’s “perpetually … modifying his technology” McLuhan (1964: 46) states that “man becomes, as it were, the sex organs of the machine world, as the bee of the plant world, enabling it to fecundate and to evolve ever new forms”. He hereby suggests a hidden complexity to human-technologic interactions, a complexity I return to later in this work. For now though, these thinkers’ opposing perspectives make a further analysis rather difficult. I recognise McLuhan’s view that there are forces at work within the “network” that need to be addressed, but accept Leiss’ view that I should view the web of interactions as a whole, in order that technological determinism cannot skew my findings. I must reconcile these perspectives in my own approach. Seeking to refrain from any dangerously deterministic hyperbole, I continue the assessment of Mobile AR as an emergent and potentially “network” enhancing new medium, but from which determinist-proof methodology?

Digital Play, though referring mainly to the digital games industry, looks into the complex dynamics between developer, distributor, market and economy. Its critical evaluation of this medium adopts a methodology that suits my own AR enquiries:

“The story of the emergence of interactive play and of its uncertain crisis-filled transformation into one of the premier industries of digital globalized capital is both exciting and revelatory. Historical perspective is vital to critical understanding. We strongly agree with Williams that it is impossible to diagnose the cultural impact of a new medium until the specific institutional circumstances of its development are understood. Moreover, critical media analysis requires historical perspective in order to argue against the deterministic view that technology “is a self-acting force which creates new ways of life [Williams, 1992: 8]”.

Kline et al. (2003:79)

Now, since Mobile AR is such a new and radical technology, it is best considered in terms of other, previously radical technologies and their own timely impact. This approach recognises the emergent nature of Mobile AR technology and the lack of current research in the field, but also allows the opportunity to reflect on the implications of this technology in a relatively safe way: that is, through the lessons learned from full-fledged media. I propose that a useful lens through which to view Mobile AR is offered by an historical analysis of Mobile AR’s better established component media, with a view to producing an understanding of the implications AR holds for society. This approach allows AR to be considered as a product of a convergence of paths: technologic, academic, social and economic, providing the basis for deeper analysis as a consequence.

Gameware: A Case-Study in AR Development

This entry is part 5 in the series An Opus to AR

I have been aided in this series by a connection with Gameware Development Limited, a Cambridge-based commercial enterprise working in the entertainment industry. Gameware was formed in May 2003 from Creature Labs Ltd, developing for the PC games market which produced the market leading game in Artificial Intelligence (AI), Creatures. When Gameware was formed, a strategic decision was made to move away from retail products and into the provision of technical services. They now work within the Broadcasting and Mobile Telephony space in addition to the traditional PC market. I use this business as a platform to launch into a discussion of the developments current and past that could see AR become a part of contemporary life, and just why AR is such a promising technology.

Gameware’s first explorations into AR came when they were commissioned by the BBC to develop an AR engine and software toolkit for a television show to be aired on the CBBC channel. The toolkit lets children build virtual creatures or zooks at home on their PCs which are uploaded back to the BBC and assessed:

The children with the best designs are then invited to the BAMZOOKi studio to have their virtual creatures compete against each other in a purpose-built arena comprised of real and digital elements. The zooks themselves are not real, of course, but the children can see silhouettes of digital action projected onto the arena in front of them. Each camera has an auxiliary camera pointed at AR markers on the studio ceiling, meaning each camera’s exact location in relation to the simulated events can be processed in real time. The digital creatures are stitched into the footage, and are then navigable and zoomable as if they were real studio elements. No post-production is necessary. BAMZOOKi is currently in its fourth series, with repeats aired daily:

BAMZOOKi, BBC's AR game show where children’s zooks compete in a studio environment

 

BAMZOOKi has earned Childrens BBC some of its highest viewing figures (up to 1.2 million for the Monday shows on BBC1 and around 100,000 for each of the 20 episodes shown on digital Children’s BBC), which represents a massive milestone for AR and its emergence as a mainstream media technology. The evidence shows that there is a willing audience already receptive to contemporary AR applications. Further to the viewing figures the commercial arm of the BBC, BBC Worldwide, is in talks to distribute the BAMZOOKi format across the world, with its AR engine as its biggest USP. Gameware hold the rights required to further develop their BAMZOOKi intellectual property (IP), and are currently working on a stripped down version of their complex AR engine for the mobile telephony market.

I argue, however, that Broadcast AR is not the central application of AR technologies, merely an enabler for its wider applicability in other, more potent forms of media. Mobile AR offers a new channel of distribution for a variety of media forms, and it is its flexibility as a platform that could see it become a mainstream medium. Its successful deployment and reception is reliant on a number of cooperating factors; the innovation of its developers and the quality of the actual product being just part of the overall success the imminent release.

As well as their AR research, Gameware creates innovative digital games based on their Creatures AI engine. They recently produced Creebies; a digital game for Nokia Corp. Creebies is one of the first 3D games which incorporates AI for mobile phones. Gameware’s relationship with Nokia was strengthened when Nokia named them Pro-Developers. This is a title that grants Gameware a certain advantage: access to prototype mobile devices, hardware specifications, programming tools and their own Symbian operating system (Symbian OS) for mobile platforms. It was this development in combination with their experiences with BAMZOOKi and a long-standing collaboration with Cambridge University which has led to the idea for their HARVEE project. HARVEE stands for Handheld Augmented Reality Virtual Entertainment Engine.

Their product allows full 3D virtual objects to co-exist with real objects in physical space, viewed through the AR Device, which are animated, interactive and navigable, meaning the software can make changes to the objects as required, providing much space for interesting digital content. The applications of such a tool range from simple toy products; advertising outlets; tourist information or multiplayer game applications; to complex visualisations of weather movements; collaborating on engineering or architectural problems; or even implementing massive city-wide databases of knowledge where users might ‘tag’ buildings with their own graphical labels that might be useful to other AR users. There is rich potential here.

In HARVEE, Gameware attempt to surmount the limitations of current AR hardware in order to deliver the latest in interactive reality imaging to a new and potentially huge user base. Indeed, Nokia’s own market research suggests that AR-capable Smartphones will be owned by 25% of all consumers by 2009 (Nokia Research Centre Cambridge, non-public document). Mobile AR of the type HARVEE hopes to achieve represents not only a significant technical challenge, but also a potentially revolutionary step in mobile telephony technologies and the entertainment industry.

Gameware’s HARVEE project is essentially the creation of an SDK (Software Development Kit) which will allow developers to create content deliverable via their own Mobile AR applications. The SDK is written with the developer in mind, and does the difficult work of augmenting images and information related to the content. This simple yet flexible approach opens up a space for various types of AR content created at low cost for developers and end-users. I see Mobile AR’s visibility on the open market the only impediment to its success, and I believe that its simplicity of concept could see it become a participatory mass-medium of user-generated and mainstream commercial content.

What is AR and What is it Capable Of?

This entry is part 4 in the series An Opus to AR

Presently, most AR research is concerned with live video imagery and it’s processing, which allows the addition of live-rendered 3D digital images. This new augmented reality is viewable through a suitably equipped device, which incorporates a camera, a screen and a CPU capable of running specially developed software. This software is written by specialist software programmers, with knowledge of optics, 3D-image rendering, screen design and human interfaces. The work is time consuming and difficult, but since there is little competition in this field, the rare breakthroughs that do occur are as a result of capital investment: something not willingly given to developers of such a nascent technology.

What is exciting about AR research is that once the work is done, its potential is immediately seen, since in essence it is a very simple concept. All that is required from the user is their AR device and a real world target. The target is an object in the real world environment that the software is trained to identify. Typically, these are specially designed black and white cards known as markers:

An AR marker, this one relates to a 3D model of Doctor Who's Tardis in Gameware's HARVEE kit

These assist the recognition software in judging viewing altitude, distance and angle. Upon identification of a marker, the software will project or superimpose a virtual object or graphical overlay above the target, which becomes viewable on the screen of the AR device. As the device moves, the digital object orients in relation to the target in real-time:

The goal of some AR research is to free devices from markers, to teach AR devices to make judgements about spatial movements without fixed reference points. This is the cutting edge of AR research: markerless tracking. Most contemporary research, however, uses either marker-based or GPS information to process an environment.

Marker-based tracking is suited to local AR on a small scale, such as the Invisible Train Project (Wagner et al., 2005) in which players collaboratively keep virtual trains from colliding on a real world toy train track, making changes using their touch-screen handheld computers:

crw 80271 | What is AR and What is it Capable Of? | Digital Cortex

The Invisible Train Project (Wagner et al., 2005)

GPS tracking is best applied to large scale AR projects, such as ARQuake (Thomas et al, 2000), which exploits a scale virtual model of the University of Adelaide and a modified Quake engine to place on-campus players into a ‘first-person-shooter’. This application employs use of a headset, wearable computer, and a digital compass, which offer the effect that enemies appear to walk the corridors and ‘hide’ around corners. Players shoot with a motion-sensing arcade gun, but the overall effect is quite crude:

ARQuake (Thomas et al, 2000)

More data input would make the game run smoother and would provide a more immersive player experience. The best applications of AR will exploit multiple data inputs, so that large-scale applications might have the precision of marker-based applications whilst remaining location-aware.

Readers of this blog will be aware that AR’s flexibility as a platform lends applicability to a huge range of fields:

  • Current academic work uses AR to treat neurological conditions: AR-enabled projections have successfully cured cockroach phobia in some patients (Botella et al., 2005);
  • There are a wide range of civic and architectural uses: Roberts et al. (2002) have developed AR software that enables engineers to observe the locations of underground pipes and wires in situ, without the need schematics
  • AR offers a potentially rich resource to the tourism industry: the Virtuoso project (Wagner et al., 2005) is a handheld computer program that guides visitors around an AR enabled gallery, providing additional aural and visual information suited to each artefact;

The first commercial work in the AR space was far more playful, however: AR development in media presentations for television has led to such primetime projects as Time Commanders (Lion TV for BBC2, 2003-2005) in which contestants oversee an AR-enabled battlefield, and strategise to defeat the opposing army, and FightBox (Bomb Productions for BBC2, 2003) in which players build avatars to compete in an AR ‘beat-em-up’ that is filmed in front of a live audience; T-Immersion (2003- ) produce interactive visual installations for theme parks and trade expositions; other work is much more simple, in one case the BBC commissioned an AR remote-control virtual Dalek meant for mobile phones, due for free download from BBC Online:

Gutter Talk

Gutter Talk: Hot & Cool in the World of Comic Books

The medium we call comics is based on a simple idea: the idea of placing one picture after another to show the passage of time. Legendary comic artist Will Eisner defines comics as ‘sequential art’. The idea that art can be ‘joined up’ to create a narrative can be seen in practice throughout the ages and is therefore not new. Examples from history include Egyptian hieroglyphics, European stained glass windows, Greek wall frescoes, Japanese scrolls and prehistoric wall paintings. In the year 1066 the Bayeux Tapestry, a 230 foot long piece of sequential art, was completed. Reading from left to right, it illustrates the events of the Norman Conquest of England unfolding in deliberate, chronological order before its viewers. Today the formula for making sequential art remains the same, though Scott McCloud’s definition is more relevant to the type of comics we have come to know. In his book ‘Understanding Comics’ McCloud states that comics are:

“Juxtaposed pictorial and other images in deliberate sequence, intended to convey information and/or to produce an aesthetic response in the viewer”

(McCloud, 1993, page 9)

This definition ignores single-panel comics such as Larson’s ‘The Far Side’, and other visual mediums like animation, but includes the use of the ‘speech bubble’ as a critical element in a comic’s narrative. McCloud’s definition lends itself to the most common forms of comics: newspaper strips, magazine-format comic books and graphic novels.

So how do modern comics work? Each panel in a comic is contained within a border. Each panel is a self-contained piece of art, and a fragment of a narrative. When read in a sequence, the gap between each panel is ‘filled in’ by the reader’s imagination. It is the reader that ‘animates’ these still pictures, not the medium itself. This happens because the mind is designed to close gaps in our awareness. Gestalt psychologists call this process ‘closure’. The real power of comics, then, lies not in the characters involved, nor what they are saying, or even the stories themselves, nor any of the medium’s potential content, but in how the reader interprets each panel as part of a sequence. As Marshall McLuhan said, “the medium is the message”.

One of the seminal media analyst’s best known concepts is that of a medium being either ‘hot’ or ‘cool’. In a broadcast on California’s CBC Television on June 22, 1965, McLuhan was asked to explain his concept:

“‘Cool’ is a slang term borrowed from the world of Jazz and popular music. The word ‘cool’ has a kind of mystical meaning that is not unlike the Hindu idea of detachment. The Hindu idea of detachment means complete involvement in an action and detachment in action. Whereas when people are merely involved in an action but not detached from the action, that’s ‘square’, or ‘hot’. Most people think of ‘cool’ as merely detached from action, but the word ‘cool’ as used in Jazz, and as I use it as sense for a medium, means a medium which uses all of you, but leaves you detached in the act of using you.”

(McLuhan, CBC.CA, 1965)

McLuhan exemplified hot media as: radio, print, photographs, movies and lectures; and cool media as: the telephone, speech, cartoons, TV and seminars. The comic book is another example of a cool medium, and to test McLuhan’s ‘Hot and Cool’ probe as a whole we will look at a comics series that typifies the medium; In the words of the great (but fictional) Professor Charles Xavier, “To me, my X-Men”.

For some, the X-Men comics are the epitomy of how all comics should be; fluid, exciting, intelligent, emotionally complex, relevant, and expressively drawn. Since their conception by Stan Lee in 1963, Marvel Comics X-Men have come very far indeed. Comparing the X-Men across the decades, panels of artwork today are richer with visual information. Comics in the early 1970s had a palette of just twelve colours. The reader had to use their mind’s eye to see the School for Gifted Youngsters that the series’ artists had in mind when drawing the series. Today, details such as old chalk-marks and lecture notes appear on the blackboard in Storm’s history classroom to give the reader a deeper sense that Mutant Academy is a real place. The characters’ facial expression are radically improved today, greater subtleties between Wolverine’s bad moods can now be conveyed, and fiery explosions are almost photo-realistic in terms of their adhering to physical law. There are now fewer gaps for the reader’s mind to fill in. Because of technological advancements and improvements in artistry, the X-Men and comic books as a whole have heated up. However, the images are still constrained within the borders of each frame. We must imagine what else is in the room when we see it from just one perspective, whereas in hotter media such as film the camera angles are generally wider, providing more information and therefore less detachment.

The panel makes up one essential part of the comic book’s construct. The second aspect is ‘The Gutter’ or the space between the panels. McCloud states that:

“Here in the limbo of the gutter, human imagination takes two separate images and transforms them into a single idea. Nothing is seen between the two panels, but experience tells you something must be there! Comic panels fracture both time and space, offering a jagged, staccato rhythm of unconnected moments. But closure allows us to connect these moments and mentally construct a continuous, unified reality. If visual iconography is the vocabulary of comics, closure is its grammar. And since our definition of comics hinges on the arrangement of elements then, in a very real sense, comics is closure!”

(McCloud, 1993, page 66-67)

Using the Gestalt definition of closure as “a principle of organization holding that there is an innate tendency to perceive incomplete objects as complete and to close or fill gaps” (TheFreeDictionary.com) and fusing it with McCloud’s concept of ‘the gutter’, in a McLuhanesque sense ‘the gutter’ becomes a very cool place indeed, completely devoid of content but for the reader’s own imaginings. There is actually an evolving art to reading or processing a comic as the guttering mechanisms become more and more sophisticated. In this way, comics could be said to be getting cooler. In some ways there’s a gutter happening whenever you turn the page too – a good example being that really ‘cool’ thing that happens when you turn the page in an action sequence (or somesuch) to a full or double page spread, sometimes with no words, and the reader really gets pulled in by the dramatic effect. Perhaps readers who are more brought up on squarer mediums, where they are more ‘spoon-fed’ with input have a harder time comprehending the narrative flow of certain comic books and so they are put off by the medium and never get to appreciate what it can offer. There are some types of comic book that require a pretty experienced reader, well versed in the ‘laws of the gutter’ and these are the coolest types of comics.

McLuhan’s thermometer is a tool for relativity, and works best when comparing multiple media. Luckily the X-Men do not appear solely in comics. They also appear in two animated television shows and have a highly successful movie franchise under their (spandex utility) belts. In a comic book, frames are viewed from up left, to bottom right. This requires active participation from the reader to help the narrative unfold. Panels can be ‘rewound’, ‘paused’ or skipped entirely. In cinema, frames on a film reel are shown to you in rapid succession and in the same place: the screen. All that the viewer has to do is sit back and let the medium wash over them. There is only a miniscule ‘gutter’ between the frames of a movie because the frame rate must be high enough to make still images on a movie reel appear to be moving fluidly. The closure between these frames is continuous, involuntary and imperceptible. The closure of frames in comics is reader dictated, involving, and necessary to the understanding of the book as a whole. This is what makes cinema hot, relative to comics’ cool.

Since VHS and, more recently, DVD became available; audiences can not only immerse themselves in a movie’s narrative from their home, but splash around a little too. Mystique and Wolverine’s fight scene cannot be rewound and played in slow motion in the cinema, but it is possible to do this at home. This makes home viewing a cooler immersive experience than cinema. The X-Men also have video games of their own, allowing a fully interactive, involving and entirely participatory immersion in the world of superheroes. In Activision’s 2004 game ‘X-Men Legends’ players can choose a team of their favourite heroes and work together to stop the psychotic Magneto. The game has its own scripted narrative, but allows real involvement that not even comic books can offer. Comics may be cool, but video games are cooler.

So what have we learned about the medium of comic books? We know that the medium consists purely of the panels in which content is placed, and spacing between the panels, which connects adjacent panels over space and time. We know now that although comics’ content is warming up as technology and craft allows, comics’ defining component, the ‘gutter’, must always remain an icy-cool permafrost desert of bleakness: Comic books would not exist without it. We have also learned that, in the Gestalt sense, comics can be seen as a configuration of elements so unified as a whole that a comic cannot be perceived by the reader as merely the sum of its parts, and that it is our own cognitive programming that turns a series of images into an involving narrative. We have learned that McLuhan’s ‘Hot and Cool’ probe still applies to varying media, but lacks a content analysis that might render it more relevant, especially with the dawn of video games as a highly prevalent medium. Hopefully though, the main lesson is that the true art of comics is not what we see on the page, but what we see in our mind’s eye.
