This is the (long-overdue) last in a three-part blog post about telling stories using virtual reality. Read all of the parts here.

For the first time in two decades, I’ve been playing with virtual reality. This time around, I’ve been using new and upcoming technologies like Google Cardboard and the Oculus Rift. I’m particularly interested in how these new experiences can be used as a storytelling medium by content creators, and the lessons we’ll learn about immersive storytelling by experimenting with them.

It seems to me that the biggest questions that VR content creators will need to start thinking about as we collectively begin to explore this new (or newly-accessible) medium are:

How do we make intuitive user interfaces?

This question mostly relates to creators making “interactive” experiences. Superficially, VR gives user experience designers a running start because there’s little that’s as intuitive as “turning your head to look around” (and, in fact, trying the technology out on a toddler convinced me that it’s adults – who already have an anticipation of what a computer interface ought to be – who are the only ones who’ll find this challenging). On the other hand, most interactive experiences demand more user interaction than simply looking around, and therein lies the challenge. Using a keyboard while you’re wearing a headset is close to impossible (trust me, I’ve tried), although the augmented-reality approach of the Hololens and potentially even the front-facing webcam that’s been added to the HTC Vive PRE might be used to mitigate this. A gamepad is workable, but it’s slightly immersion-breaking in some experiences to hold your hands in a conventional “gamer pose”, as I discovered while playing my Gone Home hackalong: this was the major reason I switched to using a Wiimote.

So far, I’ve seen a few attempts that don’t seem to work, though. The (otherwise) excellent educational solar system exploration tool Titans of Space makes players stare at on-screen buttons for a few seconds to “press” them, which is clunky and unintuitive: in the real world, we don’t press buttons with our eyes! I understand why they’ve done this: they’re ensuring that their software has the absolute minimum interface requirement that’s shared between the platforms that it supports, but that’s a concern too! If content creators plan to target two or more of the competing systems that will launch this year alone, will they have to make usability compromises?

There’s also the question of how we provide ancillary information to players: the long-established paradigms of “health in the bottom left, ammo in the bottom right” don’t work so obviously when they’re hidden in your peripheral vision. Games like Elite Dangerous have tackled this problem from their inception by making a virtualised “real” user interface comprised of the “screens” in the spaceship around you, but it’s an ongoing challenge for titles that target both VR and conventional platforms in future. Wareable made some great observations about these kinds of concerns, too.

How do we tell stories without forced visual framing?

In my previous blog post, I talked about a documentary that used 360° cameras to “place” the viewer among the protesters that formed the subject of the documentary. In order to provide some context and to reduce the disorientation experienced by “jumping” from location to location, the creator opted to insert “title slides” between scenes with text explaining what would be seen next. But title slides necessitate that the viewer is looking in a particular direction! In the case of this documentary and several other similar projects I’ve seen, the solution was to put the title in four places – at each of the four cardinal directions – so that no matter which way you were looking you’ll probably be able to find one. But title slides are only a small part of the picture.

Directors producing content – whether interactive or not – for virtual reality will have to think hard about the implications of the fact that their camera (whether a physical camera or – slightly easier and indeed more-controllable – a simulated camera in a 3D-rendered world) can look in any direction. Sets must be designed to be all-encompassing, which poses huge challenges for the traditional methods of producing film and television programmes. Characters’ exits and entrances must be through believable portals: they can’t simply walk off to the left and stop. And, of course, the content creator must find a way to get the audience’s attention when they need it: watching the first few minutes of Backstage with an Elite Ballerina, for example, puts you in a spacious dance studio with a spritely ballerina to follow… but there’s nothing to stop you looking the other way (perhaps by accident), and – if you do – you might miss some of the action or find it difficult to work out where you’re supposed to be looking. Expand that to a complex, busy scene like, say… the ballroom scene in Labyrinth… and you might find yourself feeling completely lost within a matter of minutes (of course, a feeling of being lost might be the emotional response that the director intends, and hey – VR is great for that!).

The potential for VR in some kinds of stories is immense, though. How about a murder mystery story played out in front of you in a dollhouse (showing VR content “in minature” can help with the motion sickness some people feel if they’re “dragged” from scene to scene): you can move your head to peep in to any room and witness the conversations going on, but the murder itself happens during a power cut or otherwise out-of-sight and the surviving characters are left to deduce the clues. In such a (non-interactive) experience the spectator has the option to follow the action in whatever way they like, and perhaps even differently on different playthroughs, putting the focus on the rooms and characters and clues that interest them most… which might affect whether or not they agree with the detective’s assertions at the end…

What new storytelling mechanisms can this medium provide?

As I mentioned in the previous blog post, we’ve already seen the evolution of storytelling media on several occasions, such as the jump from theatre to cinema and the opportunities that this change eventually provided. Early screenwriters couldn’t have conceived of some of the tools used in modern films, like the use of long flowing takes for establishing shots or the use of fragmented hand-held shots to add an excited energy to fight scenes. It wasn’t for lack of imagination (Georges Méliès realised back in the nineteenth century that timelapse photography could be used to produce special effects not possible in theatre) but rather a lack of the technology and more-importantly a lack of the maturity of the field. There’s an ongoing artistic process whereby storytellers find new ways to manage their medium from one another: Romeo Must Die may have made clever use of a “zoom-to-X-ray” when a combatant’s bones were broken, but it wouldn’t have been possible if The Matrix hadn’t shown the potential for “bullet time” the previous year. And if we’re going down that road: have you seen the bullet time scene in Zotz!, a film that’s older than the Wachowskis themselves?

Clearly, we’re going to discover new ways of telling stories that aren’t possible with traditional “flat screen” media nor with more-immersive traditional theatre: that’s what makes VR as a storytelling tool so exciting.

Of course, we don’t yet know what storytelling tools we’ll find in this medium, but some ideas I’ve been thinking about are:

• Triggering empathetic responses by encouraging the audience to more-closely relate to the situation of characters by putting them more-directly “in their shoes”. That Dragon, Cancer, an autobiographical game about the experience of a child’s terminal cancer, is an incredibly emotive experience… but only begins to touch upon the emotional journeys possible through virtual reality: what’s it really like to be close to somebody who’s terminally ill?
• Allowing spectators to spectate a story in their own way, or from a perspective that they choose and control. We’ve already begun to explore this as a concept with the (little-used) multi-angle feature on DVDs: for example, if you’ve got the special edition of Die Hard then you can rewatch certain scenes and flick between different cameras as you watch. But that’s nothing on the potential for future animated films to allow you to walk or fly around and watch from any angle… or in the case of interactive experiences, to influence the direction that the story takes by your actions or even just by your presence: how about a heist story in which the burglars will only carry out their plan if they can’t tell that you’re watching them, forcing you to be surreptitious in your glances over to see what they’re up to?

• Combining VR with motion simulation: Alton Towers is leading the way here, with their announcement that they’re going to re-engineer the Air rollercoaster into Galactica, upon which the ride gives the sensation of motion while a Samsung Gear VR headset simulates an otherwise-impossible spacefaring experience, and I’m hugely excited about the prospect. But a more-adaptable and economical way to achieve a similar result would be to repurpose a motion simulator: the good ones can provide the sensation of g-forces on almost any vector for an extended period of time; the really good ones can provide short bursts of g-forces at levels other than that provided by Earth’s gravity (usually by flinging the carriage around on a programmable shuttle arm, although weightlessness is still unfeasible while you remain on the ground). If you didn’t think that 2013’s Gravity was nauseating enough when it was merely in 3D, wait until you try a similar experience in motion-assisted virtual reality.
• Point-of-view framing: this paradigm has always been at least a little unsatisfying in regular movies. I mean, it might have been the best moment in Doom, but that’s more to do with how apalling that film was than how good the technique is! But the potential for stepping in to the viewpoint of another human and being able to look around has great potential for immersion-building without allowing the participant to stray too-far from the main storyline. Something that people who haven’t yet experienced VR don’t often appreciate is that a few little things can really improve the experience of immersion… things like being able to move your head, even just being a few degrees, make you feel like you’re “there”. There are some big challenges to overcome with this, of course, such as how to make the movement of the camera not make the watcher feel ‘dragged along’, especially if their experience is of moving sideways… but these are challenges that will probably be solved for us quickly by the porn industry, who’re working very hard on making this kind of experience seamless. Just like the leaps and bounds we took with streaming video, yet again technology will get to thank peoples’ love of porn for advancing what home computers are capable of.

• Exploring therapeutic experiences: until I really started trying out different VR gear, I didn’t think that it would be sufficiently engaging to be able to trigger a strong enough response to be useful in a therapeutic capacity. But after the first time I came out of a 10-minute game of Caaaaardboard! feeling genuinely wobbly at the knees in the same way as after my first parachute jump, I realised that modern VR really can produce an experience that results in a psychosomatic response. And that’s really important, because it provides a whole new medium in which we can treat (and, I suppose, study), for example, phobias in a controlled and ‘escapable’ environment. Of course, that raises other questions too, such as: is it possible to cause disorders like PTSD with virtual reality? If it’s simply the case that optimally-made VR is more-immersive than the best possible “flat screen” experiences and that it’s this that can improve its therapeutic potential, then surely it can be more-traumatic, too: I know enough people that were emotionally-scarred by Bambi‘s mother’s death, E.T.‘s almost-death, or that one scene from Watership Down that gave me nightmares for years: how much more (potentially)-damaging could a VR experience be? Whether or not it’s truly the case, it’ll only take one or two media circuses about murderous psychopaths who are unable to differentiate their virtual reality from the real kind before people start getting asked these kind of questions.
• Oh, and this webcomic, of course.

As I’m sure I’ve given away these last three blog posts, I’m really interested in the storytelling potential of VR, and you can bet I’ll be bothering you all again with updates of the things I get to play with later this year (and, in fact, some of the cool technologies I’ve managed to get access to just while I’ve been writing up these blog posts).

If you haven’t had a chance to play with contemporary VR, get yourself a cardboard. It’s dirt-cheap and it’s (relatively) low-tech and it’s nowhere near as awesome as “real” hardware solutions… but it’s still a great introduction to what I’m talking about and it’s absolutely worth doing. And if you have, I’d love to hear your thoughts on storytelling using virtual reality, too.

This is the second in a three-part blog post about telling stories using virtual reality. Read all of the parts here.

I’m still waiting to get in on the Oculus Rift and HTC Vive magic when they’re made generally-available, later this year. But for the meantime, I’m enjoying quite how hackable VR technologies are. I chucked my Samsung Galaxy S6 edge into an I Am Cardboard DSCVR, paired it with a gaming PC using TrinusVR, used GlovePIE to hook up a Wii remote (playing games with a keyboard or even a gamepad is challenging if your headset doesn’t have a headstrap, so a one-handed control is needed), and played a game of Gone Home. It’s a cheap and simple way to jump into VR gaming, especially if – like me – you already own the electronic components: the phone, PC, and Wiimote.

While the media seems to mostly fixate on the value of VR in “action” gaming – shoot-’em-ups, flight simulators, etc. – I actually think there’s possibly greater value in it more story-driven genres. I chose Gone Home for my experiment, above, because it’s an adventure that you play at your own pace, where the amount you get out of it as a story depends on your level of attention to detail, not how quickly you can pull a trigger. Especially on this kind of highly-affordable VR gear, “twitchy” experiences that require rapid head turning are particularly unsatisfying, not-least because the response time of even the fastest screens is always going to be significantly slower than that of real life. But as a storytelling medium (especially in an affordable form) it’s got incredible potential.

I was really pleased to discover that some content creators are already experimenting with the storytelling potential of immersive VR experiences. An example would be the video Hong Kong Unrest – a 360° Virtual Reality Documentary, freely-available on YouTube. Standing his camera (presumably a Jump camera rig, or something similar) amongst the crowds of the 2014 Hong Kong protests, the creator of this documentary gives us a great opportunity to feel as though we’re standing right there with the protesters. The sense of immersion of being “with” the protesters is, in itself, a storytelling statement that shows the filmmaker’s bias: you’re encouraged to empathise with the disenfranchised Hong Kong voters, to feel like you’re not only with them in a virtual sense, but emotionally with them in support of their situation. I’m afraid that watching the click-and-drag version of the video doesn’t do it justice: strap a Cardboard to your head to get the full experience.

But aside from the opportunities it presents, Virtual Reality brings huge new challenges for content creators, too. Consider that iconic spaghetti western The Good, The Bad, And The Ugly. The opening scene drops us right into one of the artistic themes of the film – the balance of wide and close-up shots – when it initially shows us a wide open expanse but then quickly fills the frame with the face of Tuco (“The Ugly”), giving us the experience of feeling suddenly cornered and trapped by this dangerous man. That’s a hugely valuable shot (and a director’s wet dream), but it represents something that we simply don’t have a way of translating into an immersive VR setting! Aside from the obvious fact that the viewer could simply turn their head and ruin the surprise of the shot, it’s just not possible to fill the frame with the actor’s face in this kind of way without forcing the focal depth to shift uncomfortably.

That’s not to say that there exist stories that we can’t tell using virtual reality… just that we’re only just beginning to find out feet with this new medium. When stage directors took their first steps into filmography in the early years of the 20th century, they originally tried to shoot films “as if” they were theatre (albeit, initially, silent theatre): static cameras shooting an entire production from a single angle. Later, they discovered ways in which this new medium could provide new ways to tell stories: using title cards to set the scene, close-ups to show actors’ faces more-clearly, panning shots, and so on.

Similarly: so long as we treat the current generation of VR as something different from the faltering steps we took two and a half decades ago, we’re in frontier territory and feeling our way in VR, too. Do you remember when smartphone gaming first became a thing and nobody knew how to make proper user interfaces for it? Often your tiny mobile screen would simply try to emulate classic controllers, with a “d-pad” and “buttons” in the corners of the screen, and it was awful… but nowadays, we better-understand the relationship that people have with their phones and have adapted accordingly (perhaps the ultimate example of this, in my opinion, is the addictive One More Line, a minimalist game with a single-action “press anywhere” interface).

I borrowed an Oculus Rift DK2 from a co-worker’s partner (have I mentioned lately that I have the most awesome co-workers?) to get a little experience with it, and it’s honestly one of the coolest bits of technology I’ve ever had the priviledge of playing with: the graphics, comfort, and responsiveness blows Cardboard out of the water. One of my first adventures – Crytek’s tech demo Back to Dinosaur Island – was a visual spectacle even despite my apparently-underpowered computer (I’d hooked the kit up to Gina, my two-month old 4K-capable media centre/gaming PC: I suspect that Cosmo, my multi-GPU watercooled beast might have fared better). But I’ll have more to say about that – and the lessons I’ve learned – in the final part of this blog post.

This is the first in a three-part blog post about telling stories using virtual reality. Read all of the parts here.

As part of my work at the Bodleian… but to a greater extent “just for fun”… I’ve spent the last few weeks playing with virtual reality. But first, a history lesson.

This isn’t the first time I’ve used virtual reality. The first time, for me, was in the early 1990s, at the Future Entertainment Show, where I queued for a shot at Grid Busters on a Virtuality 1000-CS. The Virtuality 1000 was powered by an “Expality”: functionally an Amiga 3000 with specially-written software for reading the (electromagnetically-sensed) facing of the headset and the accompanying “space joystick”… and providing output via a pair of graphics cards (one for each eye) to LCD screens. The screens were embedded in chunky bits on the sides of the helmet and projected towards mirrors and lenses at the far end – this apparently being an effort to reduce how “front-heavy” it felt, but I can tell you that in practice a  Virtuality headset felt weighty on your neck, even for its era!

Nonetheless, the experience stuck with me: I returned to school and became the envy of my friends (the nerdy ones, at least) when I told them about my VR adventure, and – not least thanks to programs like Tomorrow’s World and, of course, the episode of Bad Influence that reminded me quite how badly I wanted to get myself down to Nottingham for a go at Legend Quest – I was genuinely filled with optimism that within the decade, playing a VR game would have gone from the fringes of science fiction to being something where everybody-knew-somebody who did it routinely.

I never managed to get to play Legend Quest, and that first “VR revolution” swiftly fell flat. My generation was promised all of the hi-tech science, immersion, and magical experience of The Lawnmower Man, but all we were left with was the overblown promises, expensive effects, and ill-considered user experience of, well… The Lawnmower Man. I discovered Virtuality machines in arcades once or twice, but they seemed to be out-of-order more often than not, and they quickly disappeared. You can’t really blame the owners of arcades: if a machine costs you in the region of £40,000 to buy and you can charge, say, £1 for a 3-minute go on it (bear in mind that even the most-expensive digital arcade machines tended to charge only around 30p, at this time, and most were 10p or 20p), and it needs supervision, and it can’t be maintained by your regular guy… well, that swiftly begins to feel like a bad investment.

Plus, the fifth generation of games consoles came along: the (original) Sony PlayStation, the Nintendo N64, and – if you really wanted the highest-technology system (with the absolute least imaginative developers) – the Sega Saturn. These consoles came at price points that made them suitable Christmas gifts for the good boys and girls of middle-class parents and sported 3D polygon graphics of the type that had previously only been seen in arcades, and the slow decline of the video arcade accelerated dramatically. But home buyers couldn’t afford five-figure (still moderately-experimental) VR systems, and the market for VR dried up in a matter of years. Nowadays, if you want to play on a Virtuality machine like the one I did, you need to find a collector (you might start with this guy from Leicester, whose website was so useful in jogging my memory while I wrote this blog post).

2016 is the year in which this might change. The need for ubiquitous cheap computing has made RAM and even processors so economical that we throw them away when we’re done with them. The demands of modern gaming computers and consoles has given us fast but affordable graphics rendering hardware. And the battle for the hottest new smartphones each year has helped to produce light, bright, high-resolution screens no bigger than the palm of your hand.

In fact, smartphones are now the simplest and cheapest way to play with VR. Under the assumption that you’ve already got a smartphone, you’re only a couple of cheap plastic lenses and a bit of cardboard away from doing it for yourself. So that’s how my team and I started out playing: with the wonderfully-named Google Cardboard. I know that Google Cardboard is old-hat now and all the early adopters have even got their grandmothers using it now, but it’s still a beautiful example of how economical VR threatens to become if this second “VR revolution” takes hold. Even if you didn’t already own a compatible smartphone, you could buy a second-hand one on eBay for as little as £30: that’s an enormous difference from the £40K Virtuality machines of my youth, which had only a fraction of the power.

I’m going somewhere with this, I promise: but I wanted to have a jumping-off point from which to talk about virtual reality more-broadly first and it felt like I’d be overstretching if I jumped right in at the middle. Y’know, like the second act of The Lawnmower Man. In the next part of this series, I’d like to talk about the storytelling opportunities that modern VR offers us, and some of the challenges that come with it, and share my experience of playing with some “proper” modern hardware – an Oculus Rift.
