Our last 3D file browsing system is from much later and in a different format. It appears in the TV series Community, season 6, episode 2, “Lawnmower Maintenance and Postnatal Care”. Thanks to the scifiinterfaces reader known by the handle djempirical for this recommendation.

Community is a TV sitcom rather than a film, with short, 25-minute episodes. The setting is a small Colorado USA community college at the time of broadcast, the years 2009 to 2015, where the characters are staff and students. The series is usually described as a cult classic rather than mainstream, with lots of geeky references and shout outs (it’s very quotable). While there are plot arcs across seasons, the episodes are largely standalone. I didn’t know anything about Community when I watched this particular episode but still enjoyed it.

There are significant differences in presentation and style from our earlier films. Community is made and set twenty years later, and so both characters and audience are assumed to be familiar with personal computers, smart phones, the Internet; and to at least have some idea of what virtual reality is. The earlier films treated computer systems with respect or even awe, while here the new technology is a target to make fun of.

The characters in Community use technology, but it is not usually central to the story, unlike for example The IT Crowd or Silicon Valley. This episode is one of the exceptions. Another is episode 5.8, “App Development and Condiments”, which I strongly recommend to anyone interested in social media.

This particular episode has two plotlines, only one of which involves computers and interfaces. The easily influenced Dean of Greendale Community College has spent $5,000 (US) on a new virtual reality system called a “VirtuGood 6500”. (That the characters consider this expensive shows how much technology has changed in twenty years. Old timers like myself who remember the price tags on those elegant SGI 3D workstations mutter about kids today not knowing how good they have it.) College administrator Francesca and teacher Jeff first try to persuade Dean Pelton to locate the serial number of the system within the virtual reality world, which they need to return the system for a refund. When that fails, they must try to persuade the Dean to leave VR and return to the real world.

Note to those unfamiliar with the show: Though the Dean has a full name, in the show and amongst the fandom, he is known as “the Dean,” and so we’ll be referring to him as such. 

VirtuGood 6500 Virtual Reality World

The first scene with the new virtual reality system shows the Dean entering virtual reality for the first time.

He wears gloves and a very large headset, which are wired to a small computer worn in the middle of the back.

There is a ring around the body at waist level, sliding vertically along guide posts. It is not just a barrier to protect against falling off the platform, because the Dean is wearing a seatbelt-style harness that connects him to the ring. He stands, in socks not shoes, on a smooth plastic platform base.

While he is fiddling with straps and cables, Francesca and Jeff are reading the instructions in a 20 cm thick binder. The instructions for a new user are “When entering virtual reality you should calibrate the system by looking at your own hands, then turning them over and looking at the backs of them with a sense of wonder.” This is the first of several references to Disclosure and other earlier films.

Externally, the VR system indicates it is active by lighting up red LEDs around the front edge of the headset and around the waist ring. Internally, the system rezzes up the background from grayscale to color, and then rezzes up the hands of the avatar.

Neither the avatar nor the world are photorealistic, but since this is 2015, the graphics are much better than any similar system from the 1990s would be — even when made on a sitcom budget, rather than a feature film.

The ground plane is a polished hexagonal grid and the sky is an abstract purple pattern. Classical pillars are scattered around the landscape. A pterosaur flies overhead for no obvious reason, perhaps a reference to the old W Industries Dactyl Nightmare VR game.

Finding the serial number

The sequence we’re interested in happens just after the Dean’s initial forays into setting the timezone and clock, both of which require a complicated full-body gestural interface. Meanwhile, Francesca is reading the gigantic manual and finds that they can’t return the system for a refund without the serial number, which is stored within the virtual world.

Francesca and Jeff know that the Dean won’t want to return the VR system, so ask him to look for the file without revealing why they want it. The conversation highlights how bizarre the metaphors of this virtual world are:

• Jeff
• Go to…settings.
• Dean
• Is that in the volcano or the cobbler’s workshop?
• Jeff
• It’s a monastery.

The Dean turns his body around, which he can do because all the cables are connected to the computer on his back, not to the platform. He “walks” and then “runs” in place like a mime artist, body weight supported by the harness and waist ring. Since there aren’t any sensors attached to his legs or feet, there must be cameras or pressure sensors in the base. The avatar of the Dean runs across the landscape to the Settings monastery.

The gates automatically open as he approaches. Inside, there is a checkerboard floor rather than hexagons, more pillars around the walls, and a central pool of green water.

At the far wall is a Disclosure–style filing cabinet, but this one is gigantic. It is so big that the Dean actually has to climb up to the drawer he wants.

At least these cabinets have permanent labels, unlike Disclosure’s. Inside are, again, Disclosure-style individual files.

The Dean finds the serial number file and holds it up. Jeff asks him to print it “by dragging it to the accessories and peripherals castle and planting it in the printer garden”. But the Dean has guessed the real reason why Francesca and Jeff want the file, so instead throws the file into the air and tries to delete it. He first makes a pushing gesture, palm out, which casts a beam at the file while he shouts “Delete”.

In response the system pops up a giant text panel and also speaks the response in a slightly artificial voice, saying, “Selected”.

Since the file wasn’t deleted, we can assume that it can’t process voice input. He next mimes holding a bow and pulling an arrow back. A virtual bow and arrow appear, which he uses to shoot the file.

The arrow doesn’t do what he wants either, sorting the file. Finally he jumps into the air, catches the file, and drops to the ground. He then holds the file underwater, using both hands, in the central fountain. The file appears to struggle slightly and bubbles appear.

The bubbles stop, the file sinks and disappears, and the system responds “DELETED”.

The Dean has foiled the plan to return the system for a refund, and he stays in virtual reality. Francesca sends Jeff to appeal directly to “the architect” (a shout-out to The Matrix), local VR designer and manufacturer Elroy. There’s more quotable dialogue here, such as this description of a task which we didn’t see:

“In order to copy a file, you have to throw a fireball at it. Then absorb the fire, then drop the flaming file into a crystal lake, then take out both copies and throw them into the side of a mountain.”

Jeff is unsuccessful and returns to Greendale, but Elroy is sufficiently moved to change his mind. Elroy visits Greendale with his own VR system, a more compact and apparently wireless headset and gloves, and enters the virtual world himself, demonstrating that this is also a multi-user system.

Elroy distracts the Dean in the virtual world, giving Jeff in the real world the opportunity to disconnect him. Elroy refunds the $5,000 and takes the VirtuGood 6500 away since we never see it again. The Dean is apparently cured of his VR addiction, although a closing shot does show him experimenting with one of those cardboard headsets for a phone.

Analysis

In this episode, virtual reality and the 3D file system are deliberately portrayed as ridiculous for comedic effect. This doesn’t make it unworthy of analysis. For example, there’s this throw away line from Francesca to Jeff after the Dean has been in virtual reality for a few hours:

“He joked about wanting a pee jar earlier, and it’s gradually becoming less of a joke.”

It’s funny but also raises a real issue. Players of online computer games may do so for marathon sessions lasting many hours, and there are stories about the truly dedicated using bottles and buckets rather than getting up and leaving to use a toilet. What will virtual reality participants wearing headsets and gloves do? Wear space-suit style tubing? This is something that the serious VR literature rarely discusses, even when predicting how much time we’ll all be spending in virtual reality in the future.

How believable is the interface?

The VirtuGood 6500 is very believable for 2015. The headset is too large, perhaps because the props maker needed the extra space to keep the glowing lights and any batteries away from the actor’s face. Otherwise the headset and gloves are standard for VR, and using a backpack computer is an excellent design, removing the problem of entanglement as the user moves around.

On first viewing, I assumed that the supporting waist ring and smooth platform base were entirely fictional and built to keep costs down. Then while researching this review I found the Virtuix Omni, a VR treadmill where the user is supported by a waist level ring and walks or runs in place on a smooth surface. The only difference is that the Omni requires special shoes.

The virtual world, or at least the filing system, are also believable. The 3D graphics are well within the capabilities of a 2015 PC. The gestures we see are clear and easily distinguishable from one another. The mapping of gestures to actions may be silly, but not technically difficult.

How well does the interface inform the narrative of the story?

The 3D file browsing interface works very well within the narrative since the objective of this plotline is to make fun of it. The virtual world is full of bizarre visual elements such as the pillars that don’t support anything. The gestures performed by users are dramatic and completely mismatched with the intended tasks.

This particular system was deliberately designed to be bad, but poorly designed visual metaphors and difficult to discover gestural interfaces are not unknown in the real world. It’s a useful reminder that virtual reality systems will not automatically be easier and more intuitive to use simply because they more closely mimic the real world or are more immersive.

How well does the interface equip the character to achieve their goals?

This is another awful file browser. Even the Dean, a virtual reality enthusiast, is thwarted in his first two attempts to delete a file.

However it does succeed in the broader goal of making the user feel good. The Dean enjoys virtual reality and the sensation of power so much that he refuses to leave. It’s usually not recommended for mass market software but there is satisfaction in mastering an obscure interface that other people can’t.
