Cable Set-Top Box Arguments: Nothing But Reruns

It is inevitable that right before a major filing on an issue that the cable guys HATE!!! with all the passion of an injured monopolist, the we see a flurry of distracting nonsense designed to fuzzle the FCC, generate bad trade press, stoke the wholly-owned subsidiaries in Congress, and provide more material for the chanting cheerleader chorus. You may remember this from 2014’s: “Net Neutrality — The FCC Is Totally Gonna Lose On Banning Paid Prioritization,” and its 2015 Sequel: “No Wait, We Were Totally Lying Last Time, Banning Paid Prioritization is Cool But The FCC Is Totally Gonna Lose on Title II.”

 

Meanwhile, Comcast steps up with some “deal” that supposedly totally solves the problem they say doesn’t exist anyway so now there is no reason to do anything. In net neutrality, that was “look, we cut a deal with Netflix so you don’t need that silly old net neutrality.”

 

So it is no surprise that in 2016 we see another rerun. With comments on the FCC’s wildly popular (outside the Beltway) #unlockthebox rulemaking going on, aka the “Expanding Consumer’s Video Navigation Choices” proceeding due tomorrow, the cable industry has run true to form. Yesterday, Comcast announced it would make an ap available to Roku to let consumers stream Comcast content (under Comcast’s licensing terms, subject to Comcast control, and only to those Comcast finds sufficiently non-threatening). The fact that Comcast was messing around with the HBO Go ap on Playstation just last year  has not stopped the usual chorus of useful idiots from chanting hosannah’s of praise and declaring the problem solved. (Hopefully I will get to deal with everything wrong with the ap approach in a future post. But the short version is: “swapping one thing Comcast controls for something else Comcast controls is not “solving the problem.”)

 

But perhaps more importantly, we now come to the inevitable second act of this  well worn cable rerun. The press call headed by NCTA CEO Michael Powell with a panel of high power corporate lawyers who will trot out the same arguments they always do on why the FCC is totally gonna lose. I am eternally mystified why anyone takes this seriously because Duh, what else do you expect the cable guys to say? “Oh yeah, we don’t have a legal leg to stand on and the FCC is totally going to win. Damn, I knew I shouldn’t have drunk that bottle labeled Veritaserum!”

Nevertheless, for some reason, pronouncements by lawyers paid to make such pronouncements seem to have some mind clouding effect which not only makes people forget all the previous times these people have made exactly the same prediction, but forget the actual FCC detailed refutation of these arguments in the notice of proposed rulemaking. So once again, we here at Tales of the Sausage Factory will play the part of the annoying little dog exposing the man behind the curtain while everyone else trembles at the Great and Powerful Oz — played here by NCTA CEO Michael Powell.

Ben’s Social VR Adventure

being-of-light

There are lots of old and new VR sites with prognostications. This guest blog from a VCpreneur has four “requirements” for social VR, and it sparked some discussion at our office.

It reads to me very much like this investor fellow might be talking with some startup that features his four points, and he just wants to sort out whether the concepts are sticky. I’m imagining a company that uses Facebook for login, uploads your 2D and 3D albums and videos into your 3D space (which is zero-install via WebVR), lets you and your friends like/share from in-world, and folks that click on those shared things in Facebook get brought into your 3D space at the corresponding item. (I pitched such a thing five years ago as “Beyond My Wall”, using the Unity browser plugin instead of WebVR.)

One of the blogger’s “requirements” was that participants use their real-world identity, and this was what interested our gang, both for and against. I think this is a red herring. Although I use my real name online alot, my gut is that an alwful lot of VR is going to be about sex, and folks won’t want to use their real name. But overall, I don’t think it’s killer one way or the other. I’m guessing that he’s trying to turn the limitation of Facebook-login into a feature called real-world identity, and I think it’s a stretch. There’s clearly a lot of things that went into making Facebook win over MySpace, and I’m not persuaded that that real-world identity is the magic ingredient. Indeed, both Twitter and his other example, Youtube, are both counterexamples. I think real-world identity can be a part of many potentially successful killer apps, but I don’t see it being required for all such killer apps. (I think verified identity, whether real-world or not, will be a great service for High Fidelity to offer, but it won’t be required for everything.)

I do think he’s on the right track, though, with his feature set including pre-established friend links and content-sharing. But I’m not sure the guy has really understood why those two things matter or what they are part of. They feed the virality of a lot of social media winners, but the magic is in the viral math, not specifically in the features. For example, “pre-established friends” is helpful, but not necessary for Twitter, Youtube, or EBay. I think that each one of a Facebook liked-story, Twitter hashtag, Ebay auction, and Youtube video/discussion page forms a micro-community of interest with a specific “address” that can iself be shared out-of-band. Each user can and does “belong” to many such micro-communities. I believe that’s the real driver for virtuous-circle virality. High Fidelity is going to be great for this, because anyone can easily create any number of separate, persistent, domains of interest, and each one can have the computation shared by the people who are interested in it. (Our upcoming Beta makes it easy to organize one domain per user’s computer, which I think is a good initial model.) Nothing else I’ve seen (not even Beyond My Wall) can scale like that. This is so very different from social VR startups that offer even a large number of hosted chat rooms.

Of course, none of this is to say what is interesting about any of these domains. That is a separate – and more important – question that remains. The blog (and this response) are about what qualities are necessary, given something interesting, for it to catch on.

Separately, the comment from DiGiCT was interesting, that the huge numbers of Chinese HMD sold are just a series of upgrades to very bad/cheap/unsatisfying units. I wonder if that’s true.

H.R. 2666: House Prepares to Give ISPs License To Price Gouge (Even More).

The House Rules Committee has scheduled a floor vote for Friday April 15 (today!) for an amended version of H.R. 2666 aka the “No Rate Regulation of Broadband Internet Access Act,” aka the “Twice The Evil of the Beast” Act. Ostensibly, the bill is supposed to codify the commitment made by President Obama, FCC Chair Tom Wheeler, and just about everyone else that the FCC would never use the classification of broadband as a Title II service to engage in “utility style rate regulation.”

 

Surprise! As I explain in a much shorter version over here, H.R. 2666 basically removes the authority of the FCC to take action on any complaints relating to overcharges, fees or other nasty practices that broadband providers may do to overcharge you — provided they disclose them honestly (and, since there is not exactly a lot of competition, disclosure doesn’t help much). It also effectively strips the FCC of its authority to address zero-rating — even in the worst anticompetitive cases where a provider zero-rates its own content while applying its broadband cap (however discriminatory) to rival services. Along the way, it renders various merger commitments involving offering low cost service to the poor unenforceable and has lots of other nasty impacts.

 

Needless to say, the collective trade associations of the broadband industry are thrilled.

 

That’s not just me talking. That’s from the President’s veto threat message. Additionally, this group of 50 public interest groups think H.R. 2666 is a very, very bad bill, and 30 groups signed on to this letter explaining how H.R. 2666 will screw up privacy protection by letting ISPs charge you for it (aka “pay for privacy” like this from AT&T).

 

I’m going to repeat a pitch here I will repeat often: If you think letting broadband providers price gouge and undermine net neutrality is a bad thing, please call your Representative in the House directly, or use this link to go to BattleForTheNet.com and call your Representative (they have a tool to help find your Rep and have a script — but use your own words, that is always more convincing.

 

Made your call? Good. See below for lots more details so you can explain to your friends why they should call. . . .

How To Use High Fidelity

no-cow-tipping

tl;dr

1.Install the “Sandbox” app(We currently do not provide pre-built installers for Linux, but techies can build from open source for all platforms.) The “Sandbox” is the HighFidelity logo that appears in your system tray. (It is in the corner near where the wifi logo is on your screen, and may be behind the arrow if you have a lot of system tray apps. Sandbox starts automatically on Windows.)

2. Click on the Sandbox app and choose “Go Home” to visit your own personal domain. You can also visit another domain by clicking on a “hifi:” link that someone has given you on a Web page or email.

This is your user interface. While you use this, your actions are seen by others through your representation as an avatar.

3. Use the arrow keys to move, or the joysticks/touchpads on a hand controller. (You may need to turn on some controllers using the Avatar -> Input Devices menu.) Change between desktop display and Head Mounted Display (HMD) using the Display menu. (HMDs and controllers need to be plugged in and have their manufacturer’s software installed before starting the user interface.)

4. Most of the system behavior is defined by scripts that you can get from friends or from the Examples, or that are attached to the objects you find in the domains that you visit. Some initial behavior that you get “out of the box” includes:

  • The Go To button, giving you a directory of places.
  • The Examples button, giving you different avatars to choose from, or things to add to domains that allow it (like your own Home domain).
  • The Edit button, which lets you edit any object in in any domain that lets you.
  • Pressing the “return” key gives you an address bar to specify another place or user to visit.
  • The microphone is on! Use a headset.

If you’ve got 10 people sharing wifi, or have a Comcast connection that turns into molasses on a Friday night, things might be a bit slow when your network sucks. This is especially true when visiting a new domain for the first time. Also, some domains are faster than others. If things don’t feel right, try again later, or see “Stats”, below. Read More »

My Thoughts Exactly

St. Urhu & St. Patrick Together Call us to Our Great Heritage

Ah, Wetmachine, my child. How I have neglected you. You, who have been so much a part of my own renaissance, deserve a renaissance of your own. Perhaps you shall have it, but let’s not get ahead of ourselves. Let us rather do the least we can do to uphold our most sacred Wetmachine traditions, one of which being the observation of the annual elision of the name days of Saints Urhu and Patrick, a happy pairing that brings pride and joy to all of us Finno-Irish Americans. Whatever your heritage, dear reader, welcome. And take courage, because for the duration today and tomorrow, at least, we are all Finno-Irish!

And now, to save me the trouble of writing something new, here’s a recycled Wetmachine Urhu-Patrick piece from days gone by.

That great annual harbinger of spring, that mid-Lent quasi-Catholic dual name-day celebration for two saints (at least one of whom probably existed), that diphthong of drinking excuses, the elision of St. Urho’s Day and St. Patrick’s Day is again upon us. This, more than even the setting of the clocks ahead, gives us to know that we have survived another winter.

Now, it’s well known that Irish Americans can be very loud and unsubtle about celebrating their (our) heritage of leprechauns and bullshit artists and crooked politicians from South Boston and great singers like Ella Fitzgerald. And so of course everybody in America and around the world knows that tomorrow is Evacuation Day, I mean St. Patrick’s day, in honor of the great Romano-British Christian missionary who returned to the land of his captivity and bondage as an apostle of peace and went on to drive the serpents into the sea, (or maybe not), and so Guinness will be consumed, and cabbage, and yea, Harp Lager too, begorrah.

Alas throughout much of this country that is not the upper Midwest, the name day of St. Urhu, who drove the grasshoppers from Finland (today, March 16) is sadly neglected, to the point that we can  expect virtually no mention of it by color commentators in television broadcasts of today’s NCAA basketball games. But let it never be said that Wetmachine has forgotten the confabulated patron saint of the Finno-American diaspora (of which I am a proud member), the great St. Urhu, whose famous utterance Heinäsirkka, heinäsirkka, mene täältä hiiteen (grasshopper, grasshopper, buzz off why dontcha?) still stirs our hearts everywhere.

Statue of St. Urho in Minnesota

That saintly collusus!

It’s OK to mark this day without alcohol, but consumption of traditional all-starch foodstuffs is encouraged. So if you can find some Karjalanpiirakka, go for it.

Tales of the Sausage Factory

If McConnell Trusted His Own Party, He’d Follow the “Bork Precedent” and Hold A Vote.

There are a lot of interesting questions about the possibility that the President will appoint Judge Sri Srinivasan to replace the late Justice Antonin Scalia on the Supreme Court. For example, what happens if the D.C. Circuit has not yet voted out the net neutrality case? If Srinivasan is nominated and confirmed, would he be able to participate in an appeal of the net neutrality case? I, however, do not propose to answer either of those questions here.

 

No, I’m going to take a moment to urge Republicans to do the right thing and follow the Bork precedent of which they make so much — have a vote and reject a nominee you don’t like. That’s what the Constitution says ought to happen, and it’s a perfectly legitimate thing to do.  The meaning of “with advice and consent of the Senate” has changed a bunch over the years, but it is clearly intended as a restraint and means of forcing cooperation between the Senate and Executive, as discussed by Hamilton in Federalist No. 76.  (Hamilton thought the power to reject appointments would be little used. Unfortunately, George Washington was right about the corrupting influence of party factionalism.)

 

So why have Senator Mitch McConnell (R-KY) and Senator Chuck Grassley (R-IA), the Chairman of the Judiciary Committee, refusing to hold even a hearing on the as-yet-unnamed Obama Appointee? Fear. They cannot trust their own party to toe the line, especially the 8 Republican Senators facing difficult re-election fights in swing states.

 

While the check on the President is the need for advice and consent of the Senate, the check on the Senate is that they do their work openly, with each member accountable to their state. If Republicans really believe that “the people deserve to decide,” they would vote to reject the nominee and let “the people decide” if they approve of how their Senator voted. But of course, that would mean letting the people actually talk to their Senators while considering the vote, and potentially voting against those Republican Senators who disappointed their independent and swing-Democratic voters.

 

So the GOP elite leadership have conspired once again to take matters out of the hands of the people. Not by following the Bork precedent, which got a floor vote. Not even by filibustering the nominee, as the combined Republican/Dixicrat alliance did for Abe Fortas. No, the GOP leadership have such little trust for their own party, and the voters, that they will not even let the matter come to the floor.

Inventing the Future

The Bird Is the Word!

Believe it or not, there’s some great engineering and sportsmanship behind this:

View post on imgur.com

bird-is-the-word

We’re trying to create low-latency, high-fidelity, large-scale multi-user experiences with high-frequency sensors and displays. It’s at the edge of what’s possible. The high-end Head Mounted Displays that are coming out are pretty good, but even they have been dicey so far. The hand controllers have truly sucked, and we’ve been basing everything on the faith that they will get better. But even our optimism had waned on the optical recognition of the LeapMotion hand sensor. We made it work as well as we could, and then left it to bit-rot.

But yesterday LeapMotion came out with a new version of their API library, compatible with the existing hardware. Brad is the engineer shown above, and no one knows more than him how hard it is to make this stuff work. He was so sure that the new software would not “just work”, that he offered a bottle of Macallen 18 year old scotch to anyone who could do so. Like the hardworking bee that doesn’t know it can’t possibly fly, our community leader, Chris, is not an engineer and and just hooked it up.

chris-baring-magic-leap

In just minutes he made this video to show Brad, who works from a different office.

True to his word, Brad immediately went online and ordered the scotch, to be sent to Chris. Brad then dug out his old Leap hardware from the drawer next to his CueCat and made the more articulate version above.

We sent it to few folks, including Stanford’s VR lab, which promptly tweeted it, with the caption, “One small step for Mankind? Today we saw 1st networked avatar with fingers”.

So now we have avatars with full body IK driven by 18-degree of freedom sensors, plus optical tracking of each finger, facial features and eye gaze, all networked in real time to scores of simultaneous users, with physics.  In truth, we still have a lot of work to do before anyone can just plug this stuff in and have it work, but it’s pretty clear now that this is going to happen!

One more dig: Apple has long said that they can only make things work at the leading edge by making the hardware and software together, non-interoperable to anyone else. Oculus has said that networked physics is too hard, and open platforms are too hard. Apple and Oculus make really great stuff that we love. We make only open source software, and we work with all the hardware, on Windows, Mac, and Linux.

Inventing the Future

Makers’ Mash-Up

As the nascent VR industry gears up for The Year of VR, the press and pundits are wrestling with how things will break out. There are several Head Mounted Display manufacturerers that will release their first products early this year, and they are initially positioning them as extensions of the established games market. The idea is that manufacturers need new content for people to play on their boxes, and game studios need new gizmos in which to establish markets for their content. The Oculus will initially ship with a traditional game controller. The Vive will provide hand sensor wands that allow finer manipulation. They’re both thinking in terms of studio-produced games.

The studio/manufactuer model is well-understand and huge — bigger than the motion picture industry. The pundits are applying that framework as they wonder about the chicken-and-egg problem of content and market both requiring each other to come first. Most discussion takes for granted a belief that the hardware product market enables and requires a studio to invest in lengthy development of story, art, and behavior, followed by release and sale to individuals.

But I wonder how quickly we will move beyond the studio/manufacturer model.

I’m imagining a makers’ mash-up in which people spontaneously create their own games all the time…

  • a place where people could wield their Minecraft hammers in one hand, and their Fruit Ninja swords in the other.
  • a place that would allow people to teleport from sandbox to sandbox, and bring items and behaviors from one to another.
  • a place where people make memories by interacting with the amazing people they meet.

I think there’s good reason to believe this will happen as soon as the technology will enable it.

Second Life is an existence proof that this can work. Launched more than a dozen years ago, its roughly 1M montlhy users have generated several billion dollars of user-created virtual goods. I think SL’s growth is maxed out on its ancient architecture, but how long will it take any one of the VR hardware/game economies to reach that scale?

Ronald Coase’s Nobel-prize-winning work on the economics of the firm says, loosely, that companies form and grow when growing reduces their transaction costs. If people can freely combine costume, set, props, music, and behaviors, and are happy with the result, the economic driver for the studio system disappears.

I think the mash-up market will explode when people can easily and inexpensively create items that they can offer for free or for reputation. We’ve seen this with the early Internet, Web, and mobile content, and offline from Freecycle to Burning Man.

High Fidelity’s technical foundation is pretty close to making this happen at a self-sustaining scale. There are many design choices that tend to promote or restrict this, and I’ve described some in the “Interdimensional conflicts” section at the end of “Where We Fit”. Some of the key architectural aspects for a makers’ mash-up are multi-user, fine-manipulation, automatic full body animation, scriptable objects that can interact with a set of common physics for all objects, teleporting to new places with the same avatar and objects, and scalability that can respond to unplanned loads.

What You Need To Know To Understand The FCC National Broadband Report.

The FCC is required by Congress to do lots of reports. Of these, the one that gets the most attention is the annual Report on broadband deployment under Section 706 of the 1996 Telecommunications Act (47 C.F.R. 1302). Sure enough, with the latest report announced as up for a vote at the FCC’s January open meeting, we can see the usual suspects gathering to complain that the FCC has “rigged the game” or “moved the goal post” or whatever sports metaphor comes to mind to accuse the FCC of diddling the numbers for the express purpose of coming up with a negative finding, i.e. That “advanced telecommunications capability” (generally defined as wicked fast broadband) is not being deployed in a timely fashion to all Americans.

 

As usual, to really understand what the FCC is doing, and whether or not they are actually doing the job Congress directed, it helps to have some background on the now 20 year old story of “Section 706,” and what the heck this report is supposed to do, and why we are here. At a minimum, it helps to read the bloody statute before accusing the FCC of a put up job.

 

The short version of this is that, because between 1998 and 2008 the FCC left the definition of “broadband” untouched at 200 kbps, Congress directed the FCC in the Broadband Data Improvement Act of 2008 (BDIA) (signed by President Bush, btw) to actually do some work, raise the numbers to reflect changing needs, and take into account international comparisons so as to keep us competitive with the world and stuff. This is why, contrary to what some folks seem to think, it is much more relevant that the EU has set a goal of 100% subscription of 30 mbps down or better by 2020 than what is the minimum speed to get Netflix.

 

Also, the idea that the FCC needs a negative finding to regulate broadband flies in the face of reality. Under the Verizon v. FCC decision finding that Section 706 is an independent source of FCC authority to regulate broadband, the FCC gets to regulate under Section 706(a) (general duty to encourage broadband deployment) without making a negative finding under Section 706(b) (requirement to do annual report on whether broadband is being deployed to all Americans in a “reasonable and timely manner”).

 

So why does the FCC do this report every year if they already have regulatory authority over broadband. Because Congress told them to do a real report every year. This is what I mean about reading the actual statute first before making ridiculous claims about FCC motivation. Happily, for those who don’t have several years of law school and are ld enough to have actually lived through this professionally, you have this delightful blog to give you the Thug Notes version.

Inventing the Future

Where do we fit?

computer-dimensions

There are many ways by which to categorize work in Virtual Reality: by feature set, market, etc. Here are some of the dimensions by which I view the fun in VR, and where High Fidelity fits in.  To a first-order approximation, these axes are independent of each other. It gets more interesting to see how they are related, but, first the basics.

Scope of Worlds: How do you count VRs?

As I look at existing and developing products for virtual worlds, I see different kinds of cyberspaces. They can be designed around one conceptual place with consistent behavior, as exemplified by social environments like Second Life or large-scale MMORGs like World of Warcraft. Or they can replicate a single small identical meeting space or game environment, or some finite set of company-defined spaces. Like my previous work with Croquet, High Fidelity is a “metaverse” — a network in which anyone can put up a server and define their own space with their own behavior, much like a Web site. People can go from one space to another (like links on the Web), taking their identity with them. Each domain can handle miles of virtual territory and be servered from one or more computers depending on load. Domains could be “side by side” to form larger contiguous spaces, although no one has done so yet.

Scope of Market: How do you sell VRs?

Many see early consumer VR as a sustaining technology for games, with the usual game categories of FPS, platformers, builders, etc. The general idea is that gaming is a large market that companies know how to reach. Successfull games create a feeling of immersion for their devotees, and VR will deepen that experience.

An emerging area is in providing experiences, such as a concert, trip, or you-are-there story.

Others see immersion and direct-manipulation UI as providing unique opportunities for teaching, learning, and training, or for meetings and events. (The latter might for playing or for working.)

Some make tools and platforms with which developers can create such products.

High Fidelity makes an open source platform, and will host services for goods, discovery, and identity.

Scope of Technology: How do you make and populate VRs?

Software:

By now it looks like most development environments provide game-like 3D graphics, some form of scripting (writing behavior as programs), and built-in physics (objects fall and bounce and block other objects). Some (including High Fidelity and even some self-contained packaged games) let users add and edit objects and behaviors while within the world itself. Often these can then be saved and shared with other users.

A major technical differentiator is whether or not the environments are for one person or many, and how they can interact. For example, some allow small numbers of people on the Internet to see each other in the same “space” and talk by voice, but without physical interaction between their avatars. Others allow one user to, e.g., throw an object to a single other user, but only on a local network in the same physical building. High Fidelity already allows scores of users to interact over the Internet, with voice and physics.

Hardware:

Even Low-end Head Mounted Displays can tell which way your head is turned, and the apps rotate your point of view to match. Often these use your existing phone, and the incremental cost beyond that is below $100. However, they don’t update fast enough to keep the image aligned with your head as it moves, resulting in nausea for most folks. The screen is divided in two for separate viewpoints on each eye, giving a 3-dimensional result, but at only half the resolution of your phone. High-end HMDs have more resolution, a refresh rate of at least 75Hz, and optical tracking of your head position (in addition to rotation), as you move around a small physical space. Currently, high-end HMDs connect to a computer with clunky wires (because wireless isn’t fast enough), and are expected to cost several hundred dollars. High fidelity works with conventional 2D computer displays, 3D computer displays, and head-mounted displays, but we’re really focusing the experience on high end HMDs. We’re open source, and work with the major HMD protocols.

A mouse provides just 2 degrees of free motion: x and y, plus the buttons on the mouse and computer. Game controllers usually have two x-y controllers and several buttons. The state of the art for VR is high frequency sensors that track either hand controllers in 3-position + 3-rotation Degrees Of Freedom (for each hand), or each individual finger. Currently, the finger sensors are not very precise. High Fidelity works with all of these, but see the next section.

Capture:

One way to populate a VR scene is to construct 3D models and animated characters using the modeling tools that have been developed for Computer Aided Design and Computer Generated movies. This provides a lot of control, but requires specialized skills and talent.

There is now pretty good camera/software apps for capturing real scenes in 3D and bringing them into VR as set-dressing. Some use multiple cameras to capture all directions at once in a moving scene, to produce what is called “cinematic VR” experiences. Others sweep a single camera around a still scene and stitch together the result as a 3D model. There are related tools being developed for capturing people.

Scope of Object Scale: What do you do in VRs?

The controllers used by most games work best for coarse motion control of an avatar — you can move through a building, between platforms, or guide a vehicle. It is very difficult to manipulate small objects. Outside of games, this building-scale scope is well-suited to see-but-don’t-touch virtual museums.

In the early virtual world Second Life, users can and do construct elaborate buildings, vehicles, furniture, tools, and other artifacts, but it is very difficult to do so with a mouse and keyboard. At High Fidelity, we find that by using two 6-DoF high-resolution/high-frequency hand controllers, manipulating more human-scaled objects becomes a delight. Oculus‘ “toy box” demonstration and HTC’s upcoming Modbox show the kinds of things that can be done.

Interdimensional conflicts:

These different axes play against each other in some subtle ways. For example:

  • Low-end HMD would seem to be an obvious extension of the game market, but the resolution and stereo make some game graphics techniques worse in VR than on desktop or consoles. The typical game emphasis on avatar movement may accentuate nausea.
  • High-end hand controllers make the physics of small objects a delightful first-person experience, but it’s profoundly better still when you can play Jenga with someone else on the Internet, which depends on software design limitations. (See October ’15 video at 47 seconds.)
  • Game controllers provide only enough input to show avatar motion using artist-produced animations. But 18-DoF (in two-hand-controllers plus high-end HMD) provide enough info to compute realistic skeletal motions of the whole body, even producing enough info to infer the motion of the hips and knees that do not have sensors on them. (See October ’15 video at 35 seconds.) This is called whole-body-Inverse-Kinematics. High Fidelity can smoothly combine artist-animation (for walking with a hand-controller joystick), with whole-body-IK (for waving with your hand controller while you are walking).
  • These new capabilities allow for things that people just couldn’t do at all before, as well as simplifying things that they could not do easily. This opens up unchartered territory and untested markets.

Notice that all the mentioned interactions depend on The Scope of Object Scale (above), which isn’t often discussed in the media. It will be interesting to see how the different dimensions of VR play against each other to produce a consistent experience that really works for people.


 

A word about Augmented Reality: I think augmented reality — in which some form of VR is layered over our real physical experience — will be much bigger than VR itself. However, I feel that there’s so much still to be worked out for VR along the above dimensions and more, that it becomes difficult to make testable statements about AR. Stay tuned…

    The Pains

    The Pains

    In Freemerica, where Orwell's 1984 is fused with Ronald Reagan's 1984, a young monk tries to save the world from disintegration.

    "All three of Sundman's books are somewhere between excellent and brilliant. ... The Pains touches upon the key issues of our time: it is a book which is philosophical to the point of being mystical."

    —Michael Allen, Grumpy Old Bookman
