FTL – Activation

The Battlestar Galactica has at least two Faster-than-Light engines (which might be easier to think of as teleportation engines), activated during a complex sequence. The sequence involves:

  1. An explicit, direct command from Commander Adama
  2. Complex calculations on dedicated computers
  3. Double-checking by a large portion of the CIC staff
  4. and finally, a dedicated key and button to initiate the actual jump

Making an FTL jump is not a standard procedure for the Galactica, and it is implied that it has been decades since the ship carried out an actual jump.  This is because of the danger in landing off-course, the difficulty in the calculations, and wear on what is likely a very expensive component.  We see that many civilian ships do not have FTL capability.

The FTL engine allows the Galactica to instantly travel between one point in the star system, and another point in the star system.  Dense books of pre-made calculations are kept in the Galactica’s CIC to enter into the ship’s FTL computers.

Multiple teams each begin separate calculations, using the Galactica’s FTL computers as giant calculators for their hand-written/typed equations.  The teams then cross-check their answers against each other, using a senior officer (in this case, Lt. Gaeta) as the final confirmation.

image06

Once all teams agree on an FTL jump coordinate, the information is plugged into a separate system to “spool up” the FTL drive.

Lt. Gaeta then pulls out a special key that fits into a dedicated slot in the FTL system in the CIC.  The key has two cylindrical pins that each glow a distinct blue, and are each different lengths.  The handle of the key has a matching shape on the console as well, so that the key can only fit in one way.

Once the key is inserted, Lt. Gaeta turns the key and announces that the FTL drive is active.  Commander Adama then gives the order to jump, and Lt. Gaeta pushes a separate button (which has until now been inactive) that jumps the Galactica to the coordinates entered.

After the Galactica finishes its FTL Jump, Commander Adama asks for confirmation that they have arrived successfully at their destination.  Lt. Gaeta runs across the CIC to a navigation console and checks the screen there for the ship’s location.  From the information on that screen, Lt. Gaeta confirms that the Galactica has re-entered real space at exactly the place they were intended to be. (Or might report an error, but we never see this.)

The entire CIC lets out a breath of relief and begins clapping in celebration.  Lt. Gaeta congratulates his navigation team for their work, and the CIC slowly resumes their task of running the ship.  The CIC crew is clearly unnerved by the jump, and everyone is thankful when they arrive safely at their destination.

The Current Position Screen

image08

This is the screen that Lt. Gaeta uses to confirm that they have successfully landed at their current target: geosynchronous orbit above their target body of mass.  He does not visibly use any of the controls on the console.  The screen autonomously zooms in on the ‘X’ marker, then displays a large, red, blinking triangle with “BSG 75” written above it (The Battlestar Galactica’s registry code).  The red ‘X’ is written inside a large sphere, which appears to be the object the Galactica was attempting to jump to.

All of the lines on this graph describe arcs, and appear to be orbital paths.  The Galactica is marked as being directly on one of these arcs.  Dotted arcs connect many other objects on the screen to each other.  These have no clear purpose or legend.

At the bottom center of the screen are the words “Waypoint Time”, “Waypoint Distance”, and “T.O.T.”  Above those words is a small label: “Synthetic Gravity Field 74.56”.  To the left of those words is an area of data that has been boxed off with the label “Optic Nav System Control.”

More text to the top left lists out information in a table format, but is unreadable to the viewer due to the resolution of the screens in the CIC.  The two rows of data beside the labels do not have column headers or unit indicators.

CIC

image06

The Battlestar Galactica’s Combat Information Center, or CIC, is a medical-theater-like room that acts as the military nerve center and brain of the Galactica.  It is located near the center of the ship, is heavily armored and protected by armed guards, and has a staff of between 35-50 people.

The two highest ranking officers on the ship, Commander Adama and Colonel Tigh, typically stand at the center of the auditorium around the Command Board.  This position lets them hear status reports from around the room, and issue orders to the entire ship.

image05

Various pods of workstations provide seating for the rest of the staff.  These stations are grouped by function.  We see Navigation crew sitting near other navigation crew, weapons officers near other combat functions, communications near the center, and engineering given a special area up top.

image07

Phone kiosks are placed throughout the CIC, with two high profile kiosks on the Command Board.  Large display boards and the central Dradis Console provide information to the entire crew of the CIC.

 

Organized Chaos

The CIC is dealing with a lot of information from all over the ship and trying to relate it to the lead officers who are making decisions.  There is a lot of activity related to this information overload, but the design of the CIC has organized it into a reasonably effective flow.

Teams communicate with each other, then that decision flows forward to lead officers, who relate it to Admiral Adama.
image03

Orders flow in the opposite direction.

Admiral Adama can very quickly shout out an order from the center of the CIC and have his lead officers hear it all around him.  It can also act as a failsafe: other officers can also hear the same order and act as a confirmation step.  From there, the officers can organize their teams to distribute more detailed orders to the entire ship.

Large screens show information that the entire CIC needs to know, while smaller screens display information for specific crew or groups.

Overall, the stadium-like construction of the CIC works well for the low tech approach that the Galactica takes after.  Without introducing automation and intelligent computer networks onto the bridge, there is little that could be done to improve the workflow.

Black & Decker Hydrator

BttF_113

Lorraine prepares the family a pizza using a hydrator. She opens a sealed foil package, branded “Pizza Hut,” and removes a tiny puck of a pizza, placing it in the center of a large pizza tray. She inserts the tray into a “hydrator” oven and closes the hinged front door. A small green light illuminates on its panel. She puts her mouth close to the device and instructs it to, “Hydrate level 4, please.” A red light illuminates as a bubbling sound is heard for a few seconds. Then a timer bell rings, and both lights extinguish. Lorraine removes a full-sized and fully-cooked pizza from the oven.

It could be improved by not having her have to remember and enter the level of hydration. There might be an argument that this helps the hydrator feel like they’re doing enough effort, like the legendary Betty Crocker egg story. While snopes tells us that the usual version of this is poppycock, but also references Ernest Dichter’s research in which yes, the first generation of homemakers using instant cake mixes felt that a preparation that was too easy was too indulgent. So, perhaps the hydrator is first generation, and later generations will be able to detect the hydration needed from the packaging.  

Thumbknob

To get Jennifer into her home, the police take her to the front door of her home. They place her thumb on a small circular reader by the door. Radial LEDs circle underneath her thumb for a moment as it reads. Then a red light above the reader turns off and a green light turns on. The door unlocks and a synthesized voice says, “Welcome home, Jennifer!”

BttF_090

Similarly to the Thumbdentity, a multifactor authentication would be much more secure. The McFly family is struggling, so you might expect them to have substandard technology, but that the police are using something similar casts that in doubt.

Stark Tower monitoring

Since Tony disconnected the power transmission lines, Pepper has been monitoring Stark Tower in its new, off-the-power-grid state. To do this she studies a volumetric dashboard display that floats above glowing shelves on a desktop.

Avengers-Reactor-output03

Volumetric elements

The display features some volumetric elements, all rendered as wireframes in the familiar Pepper’s Ghost (I know, I know) visual style: translucent, edge-lit planes. A large component to her right shows Stark Tower, with red lines highlighting the power traveling from the large arc reactor in the basement through the core of the building.

The center of the screen has a similarly-rendered close up of the arc reactor. A cutaway shows a pulsing ring of red-tinged energy flowing through its main torus.

This component makes a good deal of sense, showing her the physical thing she’s meant to be monitoring but not in a photographic way, but a way that helps her quickly locate any problems in space. The torus cutaway is a little strange, since if she’s meant to be monitoring it, she should monitor the whole thing, not just a quarter of it that has been cut away.

Flat elements

The remaining elements in the display appear on a flat plane. Continue reading

Perimeter Fences

Jurassic_Park_Perimeter_Fences01Each of the dinosaur paddocks in Jurassic Park is surrounded by a large electric fence on a dedicated power circuit that is controlled from the Central Control Room. The fences have regular signage warning of danger…

Jurassic_Park_Perimeter_Fences04…and large lamps at the top of many towers with amber and blue lights indicating the status of the fence.

Main Power Board

image02

To restore the power that Nedry foolishly shut down (and thereby regain a technological advantage over the dinosaurs), Dr. Sattler must head into  the utility bunker that routes power to different parts of the park. Once she is there Hammond, back in the Visitors Center, communicates to her via two-way radio that operating it is a two part process: Manually providing a charge to the main panel, and then closing each of the breakers.

The Main Panel

image00

To restore a charge to the main panel, she  manually cranks a paddle (like a kinetic-powered watch, radio, or flashlight), then firmly pushes a green button labeled “Push to Close”.  We hear a heavy click inside the panel as the switch flips something, and then the lights on the Breaker Panel list light up green.

Now that she has built up a charge in the circuit, she has to turn on each of the breakers one by one. Continue reading

Control Room Power Board

image00

Once Dr. Sattler restores power to the park, Arnold needs to reboot the computer systems. To do this, he must switch off the circuits (C1–C3 in the screenshot above), and then switch off-and-on a circuit labeled “Main”.

image01

It’s a good thing Arnold knows what he’s doing, since these switches are only labeled C1-3, and we don’t see any documentation in the camera frame.  As he turns off each circuit, different parts of the computer terminals in the Control Room shut down.  This implies that different computer banks are tied to the same power circuits as the systems they control.

So, since this is a major interface for the park, let’s make this bit explicit: When designing infrequently-used but mission-critical interfaces, take great care to explain use, using clear affordances and constraints so that mistakes are very, very difficult to make. 

It might look like a mistake to have all the little electrical labeling to the sides, since this cover would have to be removed to get the components where this information would be of use. But that’s perfect. A user needing to remove this panel must encounter this reference information to get to those components, and so would know where to find them. This is a brilliant example of the pattern Put the Signal in the Path. Let’s hope there are similar signs on other access panels.

image02

Wait…where are the backups?

These are the central computer terminals that run Jurassic Park, and keep visitors safe from the “attractions.”  And there is no backup power.

When Arnold turns off the main circuit breaker, the computers (and servers behind them) turn off immediately.  The purpose and effect of the power switch deactivates all the systems in Jurassic Park, without any kind of warning or backup system.

For something as dangerous as deadly deadly dinosaurs—raised from the 65 million-year deep grave of extinction—the system deactivation should at least trigger some kind of warning.

Tornado sirens have backup batteries in case the city power goes out.  They are a solid example of a backup system that should exist, at minimum, to warn park-goers to move quickly towards shelter.  A better backup system would be a duplicate server system that automatically activates all the fences in the park.

Redundant Systems

When Arnold cycles the visitor center’s power system, it also trips the breakers for all of the other power systems in the park.  Primary safety systems like that should be on their own circuit.  It’s ok if the fridges turn off and melt the ice cream (though it may be an inconvenience), but that same event shouldn’t also deactivate the velociraptor pen security.  Especially when the ‘raptor pen is right next to the visitor center and is a known, aforementioned, deadly deadly threat.

Security Alert

The security alert occurs in two parts. The first is a paddock alert that starts on a single terminal but gets copied to the big shared screen. The second is a security monitor for the visitor center in which the control room sits.  Both of these live as part of the larger Jurassic Park.exe, alongside the Explorer Status panel, and take the place of the tour map on the screen automatically.

Paddock Monitor

image01

After Nedry disables security, the central system fires an alert as each of the perimeter fence systems go down.  Each section of the fence blinks red, with a large “UNARMED” on top of the section.  After blinking, the fence line disappears. To the right is the screen for monitoring vehicles. Continue reading

Iron Man HUD: 1st person view

When we first see the HUD, Tony is donning the Iron Man mask. Tony asks, “JARVIS, “You there?”” To which JARVIS replies, ““At your service sir.”” Tony tells him to “Engage the heads-up display,” and we see the HUD initialize. It is a dizzying mixture of blue wireframe motion graphics. Some imply system functions, such as the reticle that pinpoints Tony’s eye. Most are small dashboard-like gauges that remain small and in Tony’s peripheral vision while the information is not needed, and become larger and more central when needed. These features are catalogued in another post, but we learn about them through two points-of-view: a first-person view, which shows us what Tony’s sees as if we were there, donning the mask in his stead, and second-person view, which shows us Tony’s face overlaid against a dark background with floating graphics.

This post is about that first-person view. Specifically it’s about the visual design and the four awarenesses it displays.

Avengers-missile-fetching04

In the Augmented Reality chapter of Make It So, I identified four types of awareness seen in the survey for Augmented Reality displays:

  1. Sensor display
  2. Location awareness
  3. Context awareness
  4. Goal awareness

The Iron Man HUD illustrates all four and is a useful framework for describing and critiquing the 1st-person view. Continue reading
