Minecraft Earth and Dennou Coil

Recommended Posts

If you haven't already, go watch Dennou Coil, aka Cyber Coil.  It is kind of a fun sci fi about a bunch of kids and the fun they get into while wearing augmented reality glasses.

In the real world we're not quite there, yet.  Augmented reality in the real world is bounded by things like Pokemon Go and StarChart on smartphones, and Microsoft's HoloLens is still pretty bulky and expensive.  Nowhere near the nearly-invisible glasses they wear in Dennou Coil.  If you've never seen MSFT's 2015 E3 Hololens minecraft demo you should.  Microsoft obviously wants us to go there.  They've just announced their Minecraft Earth app (below), which to me looks like a portal, both in a marketing sense and a gaming sense.  Clearly - to me anyway - the plan is to get people using the app to build content and attach it to the real world so that when things like Hololens get cheap enough there will already be a rich environment to work with.

In the near future, augmented reality has become a key part of daily life. A gentle middle school girl named Yuuko "Yasako" Okonogi and her family have just moved to Daikoku City despite rumors of people disappearing. There, her grandmother, nicknamed "Mega-baa," runs a shop called Megasia that specializes in illegal tools which interact with parts of the virtual world.

Mega-baa also hosts an unofficial detective agency called "Coil," a group of children around Yasako's age who find and handle corruption of the virtual world. Yasako gets involved with the group when Fumie Hashimoto, a playful member of Coil, helps rescue her cyberdog Densuke after getting trapped in virtual space while chasing a mysterious virus. Also investigating these corruptions and viruses is an abrasive hacker named Yuuko Amasawa, who the others take to calling Isako.

Can Coil discover the truths behind the mysterious viruses and corruption, and if they can, at what cost? written by myanimelist.net

Global, augmented reality with "simple" glasses (and, perhaps, in the Dennou Could universe in the future with contacts) certainly would be interesting, furthermore I think Dennou Coil made these cyber battles really interesting (I was recommended this show after I felt let down by "Summer Wars" and its depiction of "battles" in a bit more advanced internet). Finding a way to project a new texture over literally any object IRL, is probably a bit far in the future - having 3d creatures roam the streets actually seems more feasible after Pokemon Go- but it'd probably be pretty awesome. Although the safety risk would be monumental.

I think its certainly a interesting concept to be sure. It is along the line of what Microsoft wants to focus on considering they are working a lot with VR/AR development. So something along this is not to surprising. I do think like something like PokemonGO it will need some time before it is really good though time is on its side.

Stuff like Dennou Coil is why I like "hard" SF.  It gives you a glimpse into where we are, or at least could be, going.  Sometimes it is a warning.  Sometimes it is a wonderful vision.  It is always interesting, IMHO.  Unfortunately "hard" SF is hard to get right.  You re constrained by the known, and very limited in what you can extrapolate and make into a story.  Stuff like Star Trek and Summer Wars is more entertaining for most, gets a wider audience, and is ultimately more profitable.  STEM education being what it is these days quite a lot of people can't tell the difference anyway.  Not that I'm knocking the "soft" stuff.  I can appreciate that too.  I enjoyed Summer Wars.  But to really get my brain engaged I need the hard stuff.

Current best-tech for AR/VR is anything but simple or cheap.  The hololens is $3000 last I checked, and is bulky and balky.  The stuff from Magic Leap is cutting edge and cheaper, but still not anything like the almost-not-there I/O glasses/devices in Dennou Coil.  That said, once a prototype of a device like this is built, no matter how bulky and impractical, if there's enough perceived demand then the electronics of things like the cameras that do the "inside out" positioning can be merged and miniaturized.  The software that runs on a general-purpose CPU to do those "background" tasks can be hard-coded for a dedicated, massively parallel processing chip that does that one thing far faster and cheaper and use less power besides. 

We've seen this effect already in 3D gaming with GPUs, which themselves evolved from FPGAs.  GPUs could be used in machine learning, but now nvidia and Intel are making even more specialized chips for that.  Tesla's also done their custom "FSD" - Full Self Driving - chip for their cars which consolidated, "simplified" (from an outside perspective), and made more reliable and cheaper a bunch of stuff that had been done the hard way with off-the-shelf general purpose components.

The HoloLens/Magic Leap AR gear (and some consumer VR gear as well) are already mounting outward-facing cameras that the system's software uses to position and orient the headset in the user's existing, ambient environment.  In some cases it also positions associated "peripheral" devices like hand controllers in 3d space.  This is what I meant when I used the term "inside out" positioning, above.  The position and orientation information originates from the device itself.  As opposed to "outside in", which relies on separate outside sensors pre-positioned in an environment and connected to a computer to feed the headset's position and orientation data to the VR engine. 

Clearly "inside out" is what you want in an ultra mobile device.  That's pretty hard.  The outside in method is currently the cheapest, most accurate, and most easily do-able with existing off-the-shelf components.  Unfortunately it kind of ties you down by limiting you to a predefined operational area defined by the outside sensors.  There's nothing tech-wise which is impossible in the Dennou Coil world however.  Cameras can be made almost as small as you like, and their inputs fed into massively parallel, special purpose silicon built into the frames, which in turns outputs position and orientation info to the upper layers of software.  Virtual retinal displays are already a thing.. actually kind of a solution in search of a problem like lasers were back in the day.  Smarphones can already play 3D games, and connect wirelessly to periperals and the 'Net. 

Support a VRD with a phone-sized "compute brick" that uses an inside-out headset as its user interface and there you go.  Probably won't happen any time real soon, but I see no intrinsic problems with implementation.

And yes, there would no doubt be hazards with the new technology.  There's already been people running out into traffic chasing pocket monsters.   4 billion years of evolution are wasted on some people.  SMH.

Hard SF is really the only SF I'm into, perhaps because, as you said, it gives us a glimpse at what we might have one day, in one form or another (Although I have to admit that I'm not that much of a SF fan except Cyberpunk and the 'very near future stuff' like Dennou Coil, Psycho Pass, etc. ...)


I didn't know about VRD, thanks for mentioning that. Definitely an interesting topic. Imaging having glasses/lenses connected to some kind of central computer that processes most of the stuff after receiving information from the glasses and then sending it back for the user. Something like what came up (not so) recently where you play a game which is on a pc somewhere else and you just send the (controller) input and receive the output on your screen. With fast wifi available pretty much everywhere, you could reduce the lag to a bare minimum (ofc, there's always going to be lag).

Since you mentioned cars, the FSD might, or probably will (since it's the point), change the rate at which self-driving cars improve. To go back to the idea above (doesn't have anything to do with the topic but still an interesting thought) - imagine having every car self driving, connected to servers, so that every car know the location of every other car in the vicinity, plus the traffic lights, pedestrians, etc. ... Could prevent accidents on a whole new level, plus plan traffic way more efficiently (for example have an AI [or several AIs working together] overlook the entire traffic in the region and managing every car's speed, direction, path, etc. .... You could steadily train it with simulations and rl exp. [like Tesla cars do] ) Having people run into traffic because they're trying to catch their 100th rattata wouldn't be a problem either, since this/these AI(s)  could see it coming from cameras on the different cars, public cameras, etc. ....


But if Dennou Coil taught us anything - don't fall asleep with you glasses on (or in you selfdriving car)!!

      So it looks like the US Army guys at Edgewood are saying that by 2050 cyborgs will likely be a real thing, both on the battlefield and in the general population.  Sounds like a GitS world isn't that far off.

      Didn't see one of these so I thought I'd make one! 
      Pretty much if you're looking for specific pokemon on Sword/Shield or have a pokemon that is up for grabs just post it below!

      Senki Zesshou Symphogear

      This is one of Japan's top selling anime, with 5 seasons, over the course of the past 7 years. Season 3 was #1 in sales for its season, while season 4 was ALSO #1 in sales for its season. AND season 3 beat ONE PUNCH MAN for the ENTIRE YEAR. And it isn't popular in the absolute bloody slightest outside of Japan.
      I'm confused too, don't worry.

      But if you want one of the best hype action shows of the decade, Symphogear is for you. It does damn near everything that people love about shounen action shows, except it does them far better than most actual shounens, despite Symphogear not actually being a shounen.
      AND it's a fucking musical. Didn't see that coming, did you.
      It ain't cutesy, it lives off of the rule of cool and more or less can't go more than 5 minutes without something exploding or it dies, with music that's about as cool as that whole concept is.
      Watch this scene, and witness our beloved main character parry tank shells with her bare fists.
      Watch Order:
      Symphogear (a bit rough, don't judge the show based on this season. Still good, just not peak Symphogear.)
      Symphogear G (This is where Symphogear actually starts to shine, and it stays that way. A shitty side studio fucked up the first season, so they fired them and swapped out 90% of the staff and you're left with a season that's vastly superior to the first in absolutely every god damn way you could ever expect. Get. To. This. Season.)
      Symphogear GX (It got even prettier.)
      Symphogear AXZ (The animation got better.)
      Symphogear XV (Airing right now, and is really turning out to be a proper culmination and finale of 7 years of a franchise.)
      Now that you've been so heartily informed of the best show ever, I'd love to hear what any of you think of it. First impressions based on this thread maybe, or impressions from you going to watch it! It's my favourite show by a mile, so I assure you I'm more than willing to chat your ear off about it, and if you aren't impressed by it... well, leave it to me

      If you’ve been following my recent posts, you’ll know this series has become one of my obsessions. 
      The premise is that eight teenagers, (each specializing in a particular genre of online gaming) are abducted and forced to complete a series of challenges which are streamed live. Their masked host informs that they will remain trapped until they can accumulate 100 million views. 
      The things that stand out immediately are the weird setting where realistically impossible things happen frequently and the smart-alecky banter between the characters (kinda like Haruhi Suzimiya). While the initial impression of the series is comedic, the more it progresses the more mystery, suspense & psychological it becomes. It’s becoming increasingly clear that the various characters have their own secrets and in at least one case it makes him/her potentially dangerous.
      I realize that this series is under most people’s radar. But I think @Castigear has watched a couple episodes & @LonelyPoet mentioned the manga it is based on. I thought I would see if there’s enough interest to justify a discussion or at least recommend checking it out to my fellow forum members because I’m enjoying it a lot. Here in the US you can find the dub on Funimation (the version I’m following) and the subtitled version on Hulu. Let me know what you think.
