A bleat-free view on the DK2

Early last week I received my Oculus Rift DK2 after having developed some prototypes on the DK1 (un-released) last year. I wanted to put my thoughts down in a completely hype free manner, which I feel will probably make this one of the more level headed looks at the hardware. The hype right now is pretty crazy, especially from mainstream media/entertainment/games websites. So here’s what I think, starting with what I feel are the biggest downsides and short comings. Of course, some of this may or may not be solved for the release version:

Hardware setup and cables

During setup of the hardware, I was somewhat annoyed with all the cables required, and felt like it was quite a procedure to plug everything in and set up the camera. I have two computers in my home office, one of them in a standard (I guess?) setup where the case is on the right of my desk on the floor. For the DK1/normal case position, this was simple. For the DK2 I’ve now used a case behind my desk and so the cables are quite annoying. Inevitably speaker cables get mixed with Rift cables, and elbows yank on both as you decide whether to have them under or over your arm. If CV1 has headphones built in this will make this much better, as tangling cables does suck. I prefer using ear bud headphones so I don’t have double the things on my head.

Then you have to factor in that the Rift has to/wants to live somewhere on your desk, along with joysticks, mice and whatever else. You’ll pretty much be needing an input device like a controller or joystick for the Rift, so your desk just got double cluttered! A hook on the Rift somewhere would be great to just hang off the back of my monitor.

The DK2 on my desk, with ear buds, mouse/keyboard... joystick... wheel... oh, the cablezzzz!

Camera

The camera is pretty much never going to be in a perfect position unless you have no monitor at all, or it’s magically off to one side. The 5 foot setup distance suggested is pretty unrealistic for most. Hopefully this distance is a DK2 feature and not permanent for CV1, because most people will need to mount this on their monitor, which is 2 feet away. When it’s this close, you’ll lose positional tracking past a certain (close) point to either side. If you put it farther back behind your monitor, you’ll lose positional tracking when you move your face in front of the monitor. To put it behind your monitor you need a tripod, wall mount or shelf. Sure these are all doable, but just inconvenient barriers for the normal consumer. A final point on the camera I’m unsure about – if it’s mounted on your monitor, I can’t imagine it doesn’t get knocked around a lot, messing with tracking in some way. Using a wheel or joystick is almost certain to shake everything around on your desk a little bit, including your monitor and Rift camera, disrupting or shaking your VR view(?).

Back to the cable situation – I think we still need some more customization/hooks/guides on the headset to direct them in a way that suits your setup. I hate the feeling of the cable around my neck/over my shoulder, but can’t really direct it away. I really want it just shooting off the right or left of the headset itself, but maybe you can feel the cable more that way, tugging directy at it rather than spread more evenly as it is now?

How’s your face feel?

Ok so what’s it like on your face? I’ve mostly played Elite Dangerous and Live for Speed, two of the best and most-working-est DK2 games out there. Every time I’ve played these games with the Rift, I’ve had to take it off and put it back on 2-3 times while it warms up and condensation stops forming on the lenses. So that’s pretty annoying. Once that’s settled it’s not too bad using it for around 30-60 minutes or so. After that point, I don’t know what to call it other than just fatigue. Whether it’s from the weight (it’s pretty light, though), it pressing against your face/nose bridge along with the heat, or looking at a low(ish) resolution screen, it’s hard to stay in for long. You might get some eye strain from trying to read all the now just legible text as well. Plus the foam that presses up against your skin isn’t the nicest.

From Kotaku’s article on being a space commander. I imagine my eyes look more tired and bloodshot!

The new lenses seem a little less forgiving than DK1 and require a more precise placement on your face to reduce the chromatic aberration effect, and the reduced FoV is noticeable when you’re looking for it, but not at all if you forget about it, same with the screen door effect.

Monitor > Rift > Monitor…

One of the biggest problems that will need solving is the awkward transition from monitor to Rift. This ranges from going from game to game (Rift off, select game, rift on, play game, quit game, rift off, new game, rift on…). Then you’ve got a key to recenter the rift, head set off… I’m pretty sure we will always need a re-center button(?), so maybe including one on the headset itself could be an idea? Often times I’ve been racing, wanted to reset, have to lean in to hit a key (my position is then different…) It’s a little awkward.

I almost think two buttons on the Rift could be great, one being recenter and another being ‘interface’/esc. Two buttons could do a multitude of tasks that would always be in reach, and would perhaps follow the design of Google Glass somewhat.

That Original Wow Effect?

I feel like a traitor to VR saying this, but I recall the first time I looked at a huge tree on a hill top in Minecraft and could barely believe my eyes. That tree was really truly “up there” and it was big! Now, with DK2’s new Minecrift it’s even better, there’s no motion blur, the frame rate is amazing, but now I’m used to the “VR effect”, and after a quick login/test play I didn’t get a repeat of this. I was still quite impressed with the views and increased resolution, the actually retch free playability of Minecrift. I made a little home in the mountain side, stretched my neck in all directions cutting down trees, and explored a few caves. Some of the views are great and the exploration sense is certainly heightened as you feel more that you’re actually inside these places. I’m more and more certain that it will all wear off, though. A second and third play through will likely feel a lot like playing vanilla 2D Minecraft again.

Awkwardly great

That kinda sums up the whole experience right now, awkward. Awkwardly pretty great, though. Yes it’s a dev kit, but the above points are what I see as some challenges to removing the Rift from the too-hard basket. Currently it is kinda in the same league as owning and using a steering wheel, requires similar levels of setup, and they occupy your desk in similarly annoying ways, subtly pushing you away from using them.

On the plus side for DK2? I can finally reaaaad! An amazing improvement in resolution that allows you to now actually play games and read instructions and interfaces! I can see into corners in Life for Speed and apex them properly, and only a little lean-in is required to read Elite’s interface text. The removal of the splitter box doesn’t really plus me that much, I never noticed it anyway once it was set up, and it’s been replaced by having to set up that camera.

The low persistence is really nice, and once devs have the software side working this improvement will become more apparent as we lose all judder, which is a slight problem with most demos made for Dk1 and tweaked for Dk2.

The number one thing worth talking about for me is positional tracking. Being able to move your head around in an environment both greatly adds to presence and opens up a number of game play situations. Looking around inside your ship in Elite is pretty amazing – doing simple things like standing up a little bit and looking over the front of your ship is great and really makes it sink in. Peering about the various cockpit objects for me is far more engrossing than looking out into space, potentially just because there’s so  much more depth variation close up. I’ve also found myself peering over the bonnet of my car in LFS to see if I can see damage to a wheel, and I’ve thought how cool it might be to… I dunno, check my vehicle/space craft for holes/leaks/damage in some not yet existing game.

Top Moments with the DK2

My best moment so far has probably been playing Live for Speed, despite having logged more time in Elite. If you have the full game and the DK2, I highly suggest choosing the MRT (a small open cockpit car close to the ground) and the city track. The sense of speed is amazing, and flying through that concrete chicane at top speed and hearing your engines bounce off the walls as you clip them made me laugh out loud.

In Elite, I logged in with my brother and used in-game voice for a while. We also bumped into another player and text chatted with him. In both cases the feeling of communicating with other people who occupied a ‘real’ space was pretty amazing for reasons I can’t really explain too well, other than they really seemed to be there. Typing with the Rift on though, it’s a bitch!

In Minecrift, it was getting that sense that I was carving out my own 3-dimensional home in a mountain, and later looking up from within a recently discovered cave at a night sky.

Still just a novelty?

So what do I think about this awkwardly great Rift? I’m not entirely sure yet. Part of me feels like it is a bit of a novelty and it’ll all wear off. The DK1 was so radically new and different and amazing that perhaps you can’t help but feel slightly let down when the second one doesn’t do the same all over again (despite it being much improved). I’ll certainly still be one of the first to place an order for the release version.

In LFS, am I really using VR to its fullest advantage when mostly looking straight ahead? I’ll rarely have to use positional tracking, but I sure feel like I’m there at the track, and I have an improved knowledge of my position, barrier positions, turn in points, etc. For VR, I feel car racing fits nicely into that “you couldn’t do this in real life” category where the benefits of the technology directly helps the game genre by increasing the sense of speed and gives you the ability to look around at competitor positions. The biggest downside is that, if you don’t know how the car feels to drive, you’ll probably suffer from motion sickness no matter how good the hardware. If you’re “mysteriously” losing traction and spinning/drifting, you’ll feel a bit queasy.

In Elite, again positional tracking isn’t hugely needed, you mostly look forward or around for your target, and again I feel like a VR traitor (because I do actually love the Rift) but it’s just a bit of a step up from Track IR if you don’t consider the immersion and presence. Despite the fact that the game is now completely playable in the Rift, I still get the feeling that I don’t want to play this game, because I’ve played games like it many times before over the years. When you’re ‘really, truly inside that VR space station’, you’re still weighing up if I should buy space widgets here and sell them there, or take this mission to kill space bad guy number 999. Don’t get me wrong though, E:D is a really nice step up in many ways (those sound effects!) and I’m planning on doing a complete play through at some stage, hopefully with friends or family.

Should I discard my monitor?

Another thought, VR in these games isn’t so amazingly good that its pulled me away from my current favorite non VR game, Dota2. My point I guess is that I’ll probably still be playing non-Rift games if they’re more fun/challenging/engaging. VR won’t just make all games magically the best thing ever/throw your monitor out the window. Picture this extreme example, 50 years in the future we finally have “the holodeck”. You plug in and load up your house environment that was scanned a moment earlier. It’s perfect, you can’t tell the difference between reality and VR. Unfortunately, despite this technical marvel, I’d rather go play Dota2 in real life or VR life because it’s more fun and challenging than going “wow this seems so real!”. If the same thing became some kinda “X country just invaded, defend your family in your own home”, then great, I’m in! My point is, the experience or game still has to advance beyond the same shit just with VR tacked on. Whether I’d play Dark Souls 3 in VR mode or not, I’m not sure. I haven’t been bothered using VorpX or similar to try many traditional games other than Dear Esther.

But the immersion! The presence!

Obviously you can’t say a huge improvement in immersion or presence is not a big leap for gaming, but I think the best experiences are going to be emotionally deep ones, where the message the game is giving you is heightened. I think this is mostly true of all fiction and media, the best experiences are ones that touch you emotionally and once you’ve closed the book or left the cinema (or turned off the PS3/Journey!), you can’t help but keep thinking about that story. In Star Trek, on the holodeck, if you wanted to be moved, you’d load up stories or “holonovels”.

I love action games and competitive multiplayer which have no story or meaning, it’s probably what I play most often (Dota2 for example). However games like Eve Valkyrie I feel will kind of just top out at “wow this is cool”, in the same way we think 3D is cool for the latest action film. On the other hand, having an experience like Gone Home or Dear Esther that aims to do things with your emotions, and where the focus is the environment and story, that’s what I really can’t wait for. Feeling like you’re really inside the house from Gone Home, or on the island in Dear Esther could go beyond “wow this is cool”. The house in Gone Home is a huge part of the story and the feel of that game – if you believe you’re in that house, that would really add something above just cool-factor alone.

Positional game mechanics

If we step away for a moment from any talk of story, and instead look at pure mechanics, I think the Rift doesn’t add a lot more (yet) other than positional tracking, which certainly has a lot of potential.  I’d like to see something up close and personal like The Room where you’re actively peering around and inspecting objects. Or as I said above, something where I need to inspect the vehicle I’m sitting in for damage. Something that really uses positional tracking. Super Hot seems to do this with its bullet dodging/time mechanics so I’m keen to try it. A lot of positional movement has already been covered a lot just by use of controllers for things like leaning around corners so I’m still not too sold on this being a huge thing for pushing game mechanics further.

My latest prototype

Maybe if we do something that combines both of the above things? Emotionally deep games where you inspect objects in your highly immersive environment, to help tell a story? This is what I’m working on right now – I’m prototyping stuff anyway! Being a mostly 1-man team I’ll have to choose something that’s possible within that scope, but I hope to tackle a game that only the Oculus Rift can do justice to. I’ll keep you up to date as I develop it. If you’d like to stay tuned, read more posts like this or be notified of demo releases in the future, you can sign up below:

How Will the Oculus Rift Change Game Design?

This is something I’ve been thinking about a lot, as I’m an indie developer that recently got a hold of the first dev kit. What exactly will change in terms of game design and mechanics, or what can we do differently now that the Oculus has arrived? How exactly will immersion and presence affect game design?

I’ll start with outlining what the Oculus gives us that we did not have before.

  1. Increased immersion or “presence” – the feeling that you are inside the environment.

  2. Head tracking in terms of rotation (by actually moving your head) and position (craning your head forward, back, left and right).

  3. Depth perception.

  4. Real world head/limb movement speeds

  5. Orientation issues

Then I’ll end with a few thoughts on some Oculus games and demos.

Immersion

This has been the number one touted advantage of the Rift – you are now IN the game. Big things look big, high things seem high, large drops or valleys look deep, things that are close to you seem closer, and so on. You can’t compare it to a 3D screen, the depth and sense that you are inside an environment is real. In the Oculus, my first thought (inside the Settings Viewer) was “wow, the far corner of this large room is actually quite far away, and this guy is right in my face. That door to my right isn’t *really* there”. That’s quite a thing considering the graphics:

setting viewer

I believe the main benefit of  immersion is it increases the chances for the developer to deliver the expected feeling or emotional response from events happening in-game. For example, fear, awe, danger and scale are all greatly enhanced. So how does this change things? Is the Oculus merely an enhancing effect? Scary games will be scarier, racing games will seem faster, shooters more …shooty? Also what do I mean “merely” increase immersion? I realise immersion can be pretty big for some games, but for the most part I wonder how much better or meaningful will a game be, if its got double the immersion factor, or 10x? So now you’ll feel like you’re really, really, really there! So what? This is something very hard to quantify.

If you play Call of Duty as-is but wearing an Oculus, has anything much changed just because you feel more like you are there? Will you see a fellow soldier die, and instead of chalking him up as another meaningless death, will you feel genuinely bad? I kind of doubt it. You might feel like those mortars are really exploding right next to you, though. Taking this to a (silly) extreme, if you recreated the room you are sitting in now, and had 100% perfect VR and immersion, that would be impressive from a tech standpoint, but as an experience or a game, it is meaningless.

Will the increased immersion effects wear off or is it just novelty value that we will eventually adjust to? Going back to regular games, I remember System Shock 2 scaring the crap out of me when I played it as a kid, and the best horror games these days still manage to do the same, so it didn’t wear off for 2D gaming at least. Considering Dreadhalls (made for Oculus) and forgetting how nauseous this game made me feel, the sense of terror was definitely magnitudes higher than other horror games I’ve played. If I didn’t get used to being scared in old games or movies, then hopefully the immersion effect and enhanced emotional responses on the Oculus won’t wear off either.

Finally while I don’t want to talk at length about it – the potential for significant emotional reactions could swing in a number of ways. I could imagine anything from heart attacks from horror games to people not wanting to play shooters because it feels like they’re actually killing people, to the opposite, where we get even more desensitized to violence. I’ve had dreams that feel so real that I’ll wake up feeling bad that I’ve just cheated on my partner, despite it having never happened. Will the same thing happen when VR gets really real?

Head Tracking

Head tracking feeds into both immersion and game mechanics, being able to move your head around helps immersion, but it also gives us some new tools to play with that were previously not available. In the past we’ve used controllers or the  mouse and keyboard to control both where the player walks and where they look, however this leaves us with little option for finer control of the avatar’s head. The best option is something like Arma/DayZ where you hold Alt to control your head, but this still lacks control for moving your head forwards, backwards, left and right while rotating, and you can’t aim and look at the same time. For most games this fine head control will be unnecessary, but to use DayZ as an example again, even this could benefit if you try and move your head away from a teeth gnashing zombie, or actually shift your head over/under/around objects to search for nearby zombies.

Looking at some amazing VR ground

With the ability to both move and rotate your head in all directions and dimensions, new game mechanics can open up which could involve actions such as:

  • Close and thorough inspection of objects at different distances and angles

  • Complex and fine head movement control – ie looking around inside a cockpit, over an edge, peering around corners, peeking over ledges, ducking, etc. You are no longer restricted to looking straight up or down, either.

  • Head position as a gameplay mechanic – we now have an extra control in addition to gamepad or mouse/keyboard. This could allow more complex games or capitalise on a single mechanic as in Dumpy the Elephant, where you control the Elephants head and attached trunk with your own head movements. In this instance immersion is increased as the trunk feels like an extension of your own head.

  • Social actions, ie – nodding to multiplayer friends in a conversation, nodding in the affirmative instead of hitting the A button to agree with an NPC. These mechanics also increase immersion.

To carry on talking about Dumpy, this is a good example of a game that could have been designed without the Rift, and would have still worked, however with the Rift it reaches a new level because your head movement is linked to the elephants – you are moving your head as if you are an elephant. It gives you an extra hook into the game world that wouldn’t be possible by just swinging your hand/wrist around with a mouse.

Depth Perception

As an elephant, being able to see down your trunk in full 3D adds another level again – with it almost coming out between your eyes. Depth perception is linked to immersion in terms of boosting the effect of being somewhere inside an environment, but could also help players nail the apex of a corner, make contact with a melee swing, and get scared shitless by a monster that’s right in their face.

dumpy

Emotionally, I could see depth being a huge factor as well. Imagine looking at an NPC you’ve grown attached to slipping out of your fingers to their doom, Cliff Hanger style, or being right next to someone who’s hit by a car. Perhaps imagine a Bond moment where a buzzsaw or syringe is approaching your face… Again, for horror games turning around and seeing a monster face-to-face is terrifying as was evidenced when my partner slammed my new Rift into the table after ripping it off her face.

Reactions to other players or NPCs could be amplified if they move right in close to you. An aggressor could scream right into your face, or a love interest could slowly move in. Someone could lean in and whisper into your ear, a zombie could bite your face off, etc.

On a slightly more shallow note – all those fancy special effects and particles are sure gonna look pretty as you move through them!

Real World Movement

Real world head movement may even slightly restrict game design choices (although restriction of choices in art is rarely a bad thing). With the Oculus, you can only turn your head or move the view at a certain speed based on the player’s own neck muscles, or in terms of rollercoaster style games, you can only push different movement speeds in so many directions before making the player sick.

If you’re playing in 1st person, you’ll have to be a creature with a single head, neck and two eyes (sure, it’s not common to be a 10 headed, neckless cyclops or something), so while being an elephant or a Grey alien is doable, being a giraffe might not work quite so well. Also consider something like a bird, which travels horizontally with their body out behind them while the player themselves sits upright in chair. Gravity is working against game design choices like this. However, having played a few space games so far, the effect of being upside down with incorrect gravity isn’t so bad.

We also have to consider restriction of movement. You can’t have an NPC put the player’s avatar in a headlock for example, or restrain their head movement in any way, because the player can simply move their head. If you have the player moving through a very tight space, he can crane his head forward and just move through the geometry. I hear that in some demos, developers have blurred and/or darkened the screen when this happens. Perhaps this is a solution for restricting movement too?

Unexpected movement is another thing to think hard about. This can range from a camera move in a 3rd person game (perhaps the camera moves to avoid a wall or moves for a cut scene) to unexpected movements based on physics . If you play Wingsuit or Warthunder, despite their realistic physics models these games can cause somewhat unexpected up and down movements that causes your stomach to really churn. The more simple and direct the movement, the better, at least with the first dev kit.

Peripheral Movement

In addition to real world movement for the Oculus, peripherals like Razer Hydras can suffer from similar problems where the player attempts to move in a way that isn’t matched 1:1 to the game environment. For example, imagine in-game swinging a huge heavy axe with your nice light Hydras – there will be a mis-match between the speed you can swing in reality vs the game world.

Orientation

When playing normal games on a detached 2D screen, it doesn’t much matter which way you’re facing, which way gravity goes, or how much you spin or flip. However when you are immersed into an environment, these things become an issue for your stomach, and sometimes for immersion. Consider my awesome art below:

oculus orientations

Comparing your sitting position to the type of avatar/orientation. From left to right – elephant, bird, upside down space ship, scuba diver

Whether or not some of these conflicting body/avatar positions are a problem will probably come down to feel. I personally didn’t have a problem with the elephant or space ships, but I did feel odd as a bird. Games like Lunar Flight or other cockpit games on the other hand really feel like they click.

Existing Game Demos

I’m going to end this post with a breakdown of a small selection of games and how they utilize the Rift, as well as some potential problems with some concepts.

Lunar Flight

I think this is the best example so far of a game that uses all of the Oculus’s features to best effect. When DK2 comes out with head position tracking, it will be even more so. Seated in a Lunar Lander, I’m seated as I am in real life, looking out the cockpit of the Lander. I feel like I’m really in the Lander, the scale is perfect, I can judge depth well enough to land on target locations and the interface is designed well. I also like the fact that I have to look around to use the interface, rather than straight ahead, making more use of screen real estate and the Rift. When positional tracking comes out, I’ll be able to lean forward and judge my landings with even more precision, or look around a strut/monitor that’s in the way of my view of the Earth. Can’t wait!

Lunar Flight Link

Dumpy the Elephant

The number one thing that separates this game from others is that you move your head to control the elephant’s head and trunk. That, coupled with the immersion gives you a pretty solid feeling of being an elephant despite the cartoony graphics. I’m a huge fan of the art style, and its great to see people using non-realistic graphics so soon. Amazingly, considering the amount of head movement involved, I never get nauseous.

Dumpy Link

Ambient Flight

I like the concept for this game, and it looks amazing, and a flying game for the Rift is just a no-brainer. However I feel a big disconnect being seated upright myself, vs horizontal as the bird avatar. Funnily enough though, I didn’t get this with Dumpy. I feel that this game might also benefit a huge amount from something like the Stem controller, where you’d need to spread your arms out to fly and maneuver, maybe even flap them like wings. The main benefit to this game is the immersion of the Rift, where you feel like you are in the air. This game may also cross the line a little between an experience and game, where (at least currently) there are no challenges or goals of any kind. Once you’ve played this once, you’ll possibly never replay again, but with so many experiences to be had on the Rift, I think this might be quite common. I suppose you may return to it just to chill out and fly around.

Ambient Flight Link

DreadHalls

With the first dev kit, I universally dislike all FPS’s because it induces the worst nausea for me. However I’ve seen a few let’s plays and my friends had a go and they were all fine. Hopefully DK2 solves this for everyone and most game types. Having said that, Dreadhall’s use of the Oculus makes great use of real world movement, as you can’t look left and right any faster than your head will allow, and positional tracking will be amazing for peeking around corners. Monsters can feel like they are right behind you, and you can’t pull a superhuman turn/run backwards to see. This game and perhaps the horror genre feels like the easiest to link immersion to a better game, as being immersed in a scary environment elevates the terror by such a degree. A very real problem with the sheer terror factor for this game is that I don’t actually want to play it. This is something I’ve seen and heard in other reviews/youtube playthroughs as well – there might be a limit to how much you can handle while playing a good, immersive Oculus game! Just imagine we reach an Exorcism of Emily Rose level of terror in VR, yikes! At the same time, who can pass up trying something that someone tells you is too scary?

Don’t play it here(!)

Conclusion

The future of game design with the Rift is quite an unknown – we still have such a small number of demos available, most of them just bite sized experiences, so its hard to judge yet what a fully developed Oculus game will be like with the consumer version. Here’s to hoping that what we get isn’t mostly “what we have now, plus a Rift on your face”. Games like Lunar Flight, Dumpy the Elephant and Dread Halls are some great steps forward, and I think the technology will really make developers dream big and try things that haven’t been done before.

For Rift experiences, I’m also looking forward to everything from 360 degree videos to sunny beach simulators, to dioramas like Blocked In.

Thanks for reading, very keen to hear people’s opinions on how the Oculus will change game design, how immersion will affect how games are made, how I said a stupid thing, or any other comments you have!
