Library Computer Access and Retrieval System

The Library Computer Access and Retrieval System ( LCARS for short) was the main computer system employed by the United Federation of Planets by the mid- 24th century . It was used aboard all Starfleet vessels, starbases , and space stations . ( Star Trek: The Next Generation ; Star Trek: Deep Space Nine ; Star Trek: Voyager ; Star Trek: Picard )

Interfaces [ ]

A standard LCARS display circa 2379

LCARS was accessible virtually anywhere in a facility or starship by both voice and keypad commands via control interfaces . These interfaces included bridge stations, consoles , PADDs , tricorders , and desk computers. Typically, these were graphical controls housed underneath touch-sensitive clear panels that could be quickly reconfigured by users to suit the task at hand. There were also tactile interfaces for visually-impaired officers. ( TNG : " Encounter at Farpoint ", " The Vengeance Factor ", " The Host ", " Half a Life "; VOY : " Year of Hell ")

A holographic LCARS display circa 2399

By 2399 , Starfleet had begun deploying three-dimensional holographic interfaces for the LCARS system aboard Federation starships and installations. Civilian craft such as La Sirena also had access to this technology. However, even by 2401 , touch-only interfaces remained the de-facto standard aboard Federation starships, such as the USS Stargazer , and USS Titan -A . ( Star Trek: Picard )

Operation [ ]

LCARS used sophisticated subroutines in order to understand and execute vocal natural language commands. This enabled even complicated tasks to be executed with just a few commands in the case of voice or button presses in the case of keypad commands. LCARS controlled the retrieval and storage of files in the data banks housed within the ship's computer cores including logs like personal logs or transporter logs , element and chemical compound data and data on archaeological artifacts . ( TNG : " Contagion ", " Dark Page ", " Man Of The People ", " Night Terrors ", " Qpid ") It was used to retrieve files in external databases like when a ship needs to assess traffic control around starbases or investigate inventory databases of surplus depots. ( TNG : " Birthright, Part II ", " Unification I ") It was also used for command system access and for viewing the crew manifest . ( TNG : " Brothers ", " Conundrum ") It was also used to display recently recorded data like medical scans, tactical scans and sensor scans. ( TNG : " Ethics ", " Interface ", " Descent ", " Relics ", " Genesis ") It displayed results of analyses like linguistic analyses, configuration analyses of system networks, and magnetic flux density analyses. ( TNG : " Masks ", " Attached ", " Power Play ")

LCARS retained the same basic layout and design across Federation starships and installations, however, a few variations in the color schemes can be noticed.

During normal operations, LCARS color schemes could alternate between a wide ranges of colors, such as tans, purples, and yellows, in addition to blues, aquas, and oranges. ( Star Trek: The Next Generation ; Star Trek: Deep Space Nine ; Star Trek: Voyager ; Star Trek: Picard )

A display monitor showing the red alert color scheme

During emergencies or special operations, LCARS color schemes were updated to reflect the current alert status, such as red or blue alerts . When these alerts were called, LCARS interfaces switched to either a red/white or blue/white scheme, respectively. ( Star Trek: Deep Space Nine ; Star Trek: Voyager ; Star Trek Generations ; Star Trek: First Contact ; Star Trek Nemesis )

In the alternate timeline of the anti-time future around 2395 , LCARS was still used and similar in appearance to its mid- 24th century version. ( TNG : " All Good Things... ")

Background information [ ]

LCARS interfaces are seen in almost every episode of Star Trek: The Next Generation , Star Trek: Deep Space Nine , and Star Trek: Voyager . The interfaces seen in Star Trek: The Original Series are never named and their designs are quite different.

A close-up view of one of the science stations aboard the Enterprise -D in "The Vengeance Factor" has the label "Library Computer Subsystems". [1] The full name "Library Computer Access and Retrieval System" can be seen in several episodes, including " The Price ", " The Measure Of A Man ", and " Conundrum ". The phrase "library computer access and retrieval" is spoken in " Encounter at Farpoint ".

TNG-style LCARS displays in Star Trek V: The Final Frontier

The sickbay used in Star Trek V: The Final Frontier is a minor redress of the TNG sickbay, and the LCARS panels on the wall are barely altered, so this could be the first LCARS appearance. They also appear in Star Trek VI: The Undiscovered Country just below the warp core, but they do not appear in the 23rd century portion of Star Trek Generations .

According to a Next Generation episode text commentary by Michael and Denise Okuda , the LCARS displays were rarely actual computer simulations; one such example was the computer screen used by Romulan Commander Sela to monitor the Federation fleet during her attempt to smuggle weapons and supplies to Lursa and B'Etor during the Klingon civil war in the episode " Redemption II ". This was due, according to the Okudas, to both the high cost and primitive state of computer graphics in the late 1980s and early 1990s. Therefore, most LCARS displays were, in fact, plastic panels with spinning light devices behind them to give the impression that the information on the "displays" was changing.

In the first two seasons of The Next Generation , large black rectangles are clearly visible on the LCARS displays on the bridge (and sometimes in main engineering). This was a result of the studio lights reflecting off the displays, which director of photography Edward R. Brown tried to solve by sticking cardboard onto them. When Brown was replaced by Marvin V. Rush for the third season, a number of changes in filming (including better film stock and a smaller number of lights) allowed the LCARS displays to be seen properly. [2]

LCARS as seen in the DS9 CD Companion

The interface was updated for Star Trek: Picard by a team that included playback supervisor Martin Garner , creative director Chris Kieffer , and designer Andrew Jarvis . [3] The new palette used in season one included the hex triplet values: E7442A, 9EA5BA, 6D748C, 2F3749, and 111419. [4]

Apocrypha [ ]

The LCARS layout has been used in several computer games and applications such as the CD-ROM version of the Star Trek Encyclopedia , as well as the TNG and DS9 CD-ROM Companions. The LCARS layout is also used on the Star Trek PADD app for the Apple iPad .

LCARS Interface – build your own

LCARS interface – build your own: is an article to bring a science fiction Star Trek’esque interface into real world usage.

As I examined in the article Science Fiction into Science Fact , there are many tools we can use for ourselves these days that were previously only the realm of science fiction.

Working with KeyRings from WhereWeLearn, this example provides a step by step guide to building your own working LCARS interface.

The original interface  was originally designed by scenic art supervisor and technical consultant Michael Okuda.

You’ll need a few things, all of which are available Free of Charge.

The Video Version

There is a video of the process of building and putting live an LCARS Interface here

However for easy reference and find-able with a Google search, a step by step instruction reference is here too.

Step 1. Inspiration

Go to Google and search for “LCARS examples”

Click the Images tab and be inspired.

https://www.google.com/search?q=lcars+examples

Step 2. LCARS Interface Fonts

Firstly you’ll need some fonts for you LCARS Interface.  Easily managed thanks to the team in Star Trek Minutiae

http://www.st-minutiae.com/resources/fonts/index.html

Through experimentation I’ve found Nova Light Ultra SSi quite visually appealing for any LCARS Interface.

Both Nova Light Ulatr SSI and Context Ultra Condensed are free for personal use.

Copyright c 1992 Southern Software, Inc. All Rights Reserved

You can use any sans serif thin font to match the style.

This LCARS Interface is being used for public benefit and not for commercial gain.

Kudos to Southern Software, Inc. for making this font.

Step 3. Colours

Depending on which example you’ve gone for a sample of colours that works for you is in order.

I found this example on Pinterest from Alexander Richardson in 2009.  His email as per the image [email protected]

The USS Defiant with a few “tweaks” in it from the author makes for an amazing LCARS Interface.

I found a much fuller collection here of these ship diagrams here. 

Consequently I worked through the image and extracted the colour pallet for the buttons.  Also I left the two blue colours in the diagram out of the palette.

Step 4. LCARS Interface is just boxes on top of boxes

If there’s anything in this article you’d like to chat to me about or help me with you can contact me here or on social media.

• Firstly a black square to cover the background.
• Secondly the red rounded box next
• Thirdly the lime green rounded box
• Next up was to add the two round ended boxes in blue
• The tall purple box creates a uniform gap
• Finally then two text boxes using the Yellow font colour

Then some very easy recoloring

• Firstly leave the background alone
• Secondly set the red box to the grey colour from the palette above.
• Next up, lime green goes to black
• Also the two blue ends to the grey
• Easily swap the tall purple to black
• And hey presto…

Step 5 – Your buttons on the LCARS Interface

I popped another box in the middle with some details and colours on the sides to make it a bit more of a “Star Trek” esque LCARS Interface.

Now when I add in three simple rounded boxes, I align the font right and with the bottom of the button.

The colour palette works together and is complimentary and an easy on the eye LCARS Interface

From that you can add as many buttons as you like, with whatever you want on them

Step 6. From Presentation to Image

Quite simple Ctrl and tap the letter A for all.  This will copy your entire LCARS Interface.

Open a drawing program like MsPaint on your computer.  You can see this in the video.

I thoroughly recommend using GIMP (GNU Image Manipulation Program) … it’s awesome and it is free.

In the program, ctrl and V for Paste…. and there’s your new image.

Save it to your machine as a .jpg or as a .png.

Step 7. Online hosting

If you have online hosting you’re golden, just put the image online.

If you don’t have hosting, you can use a service like ImgBB

Again there’s a step by step using this approach in the video.

You will end up with a URL for your LCARS Interface. Mine ended up being….

https://i.ibb.co/Pm7JvQH/building-a-display-04.png

Step 8.  Making your LCARS Interface interactive

For this bit you use the URL you generated in the last step and a great online tool from the team at Image-Map.net

https://www.image-map.net/

This step is far easier explained using a video.  Not only that, how about a quick explanation on how to get it into WhereWeLearn as well.

Step 9. WhereWeLearn and sharing your LCARS Interface

Now that you have an Image Map and an Image URL… time to let the WhereWeLearn engine help you.

Please let me know about your LCARS interfaces.

Raspberry Pi Takes Star Trek UI To Red Alert

'Make it glow!'

Not everyone has the luxury of making their way onto a Starfleet-operated starship but if you’re craving the experience, you’ll have to settle for the next best thing. Today we’re sharing an incredible LCARS interface project put together by Rob, also known as meWho_System47 over at Twitter, who worked with James Mitchell to make it run on our favorite SBC, the Raspberry Pi .

LCARS is an acronym from the Star Trek universe that stands for Library Computer Access/Retrieval System. The user interface design was created by Michael Okuda a a means to convey a complex computer interfaces, using backlit plastic panels. This interface can be seen on screens throughout the series and is loved by fans for its unique design. This custom LCARS UI project is packed full of features for the modern Star Trek fan and can even interact with real-world technology.

In the real world, Rob, who created the System 47 screensaver, shared some of the features but you’ll have to check it out yourself to dig into the meat of the project. It includes a cross-section, known as a Master System Display (MSD) of the USS Cerritos ship found on the animated series Star Trek Lower Decks . Users can find images from the real-life James Web Space Telescope (JWST) and interact with an alarming Red Alert system—just in case you come across some nefarious individuals while perusing imaginary space.

While anyone can interact with the custom LCARS interface on Rob’s website, he and James found a way to host it on a Raspberry Pi. The duo managed to hook up the interface to real LEDs so that pressing the Red Alert button will cause them to react. When the Red Alert system is activated, the LEDs flash and the alarm sounds will a pulsing effect.

The team explained that the LEDs are able to operate in sync with the application by using web sockets. The Python module Flask is used to create a website, using a copy of the Ritos website from Rob. Flask uses socket.io to wait for a trigger from the client. The client changes the alertStatus, which is sent to the Flask server via a websocket. The change is then broadcast to to all listening clients, one of which is a Raspberry Pi Zero 2W which is connected to a set of Pimoroni's Mote sticks (PCBs with embedded APA102 RGB LEDs). The user interface is a Raspberry Pi 3B running the official touch screen, and Chromium browser running in kiosk mode to give it a true LCARS experience.

You can find more information as well as a video of the setup in action over at Twitter in a post shared by James.

If you want to experience this Raspberry Pi project for yourself, or maybe just play with the LCARS project, check out the original Twitter thread and head over to Rob’s website to click around and play Starfleet from the comfort of your browser window.

The main screen

After you have clicked on the logo or the text link "Login" on the LCARS overview page , the main screen of the Star Trek Dimension LCARS terminal will be displayed after a short time of loading. Its functions enable you to view all LCARS files and, moreover, allow searching the database, working with cross links and accessing data from the various sub databases. Please activate the "fullscreen" feature of your browser in order to make your experience even more realistic.

The functions

As mentioned, the menu provides you with five different database functions (plus "logoff", of course), so that you are given a great number of access- and retrieval functions. You will learn here more about these possibilities, and how they work.

The LCARS pages

The LCARS pages themselves have a standardized layout which is very similiar to the original screen display of The Next Generation, Voyager and Deep Space Nine in terms of colors and general composition. The files are structured strictly hierarchically and contain tables and lists as well as text descriptions. Of course you will find plenty of diagrams, photos, mini pictures and sounds as well. Generally, headings are printed purple, key words and sub headings yellow and normal text white. As there no "links" as such in the 24th century, they are usually also white and become only visible by putting the mouse cursor on them. Some mini pictures contain links to related pages as well. You can navigate through the page(s) with the up to 6 buttons displayed in the left area of the tree-like LCARS structure. As you might notice, the display area does not have a scroll bar (what would be another unwanted Windows element), however, this function is emulated by the two red buttons marked with arrows. Use them just as the arrow buttons of the Windows scroll bar in order to scroll through the page. Depending on the sub database, you will find up to four cross references to topic related pages between the scroll buttons. The content of those pages should become clear because of the labels of the cross reference buttons: "Exterior" will show you the exterior view of a ship or space facility, "Interior" an interior view, "Technical" further technical specifications etc.

LCARS (Library Computer Access/Retrieval System) is the iconic science-fiction UI designed by Mike Okuda for Star Trek: The Next Generation and used in all Star Trek productions that take place in the late 24th century.

Many recreations of LCARS exist as static graphics or as Flash animations. This project shows that one can develop a responsive LCARS interface entirely with modern web technologies. The interface responds to fit any screen and collapses to a minimal form for mobile devices. Even works on PADDs (ahem, tablets)!

Can I have permission to use your LCARS Computer Screens for my own Star Trek site? Only those that are available at my MSD page here. All other displays are not available. When I started out making my site, it took me a long time to master animations and each one takes a long time to compile. All other animated gifs and movies can be downloaded. Although I have no real way to prevent you from taking or using my files from my site. However, if you want your site to have a look of originality, then I recommend you learn how to build them. Can you send me the source Flash files you used? No, I cannot as these are an in-house resource and I will not and cannot afford to share them.

Trek LCARS Android Apps By NSTEnterprises

Hello, I’m the developer NSTEnterprises.

Some of you know me and have been following and using my ✦TREK✦ Apps for years. My apps have been on the Google Play Store since 2014, but are still relatively unknown.

I currently have 22 apps that can change your home screen interface, dialer apps, SMS/MMS texting apps, note apps, notification soundboards, and a lot more. I make the apps completely immersive with the looks and button sounds you love in a few ✦TREK✦ styles.

I’m a big Sci-Fi fan, and I actually started doing this in 2011. I noticed there wasn’t anything available I wanted and nothing up to my perfectionist standards.

So, I started playing for personal use. Eventually, I got on the Play store to sell the apps as a supplemental income (to justify the time spent on it to my wife). I’m actually amazed at how much I’ve managed to do in just my spare time while having a full-time job, 2 kids, and a house I’m constantly working on.

I dream of my apps taking off enough to allow me to stop my regular job and focus on this full-time. If that happens, you can expect a lot more ✦TREK✦ apps from me, and I’d finally be able to look into making something similar for Windows.

Unfortunately, because I’m pretty hidden by the algorithms, I have to rely on word-of-mouth, and people actually directly looking for something like my apps [and then scrolling for a bit]. So, if you get my apps, reviewing and sharing on social media would really help. I know millions of people would want my apps, but they have to know they exist to get them.

How To Start With My Apps

First, here is my complete list of apps: https://play.google.com/store/apps/developer?id=NSTEnterprises

and more than that on the Amazon App Store: http://www.amazon.com/gp/mas/dl/android?p=com.treking.treksounds.newBoardpro&showAll=1 (especially the New Trek style)

For the New Trek-style, I had to put the SMS, Notes, and Dialer exclusively on Amazon as it uses the same code as the more popular Total Interface versions and Google doesn’t consider a different UI as a different user experience for their new repetitive content policy.

I recommend starting by changing your home screen/launcher which is more than enough for most, but you can expand on it with the other components.

TREK: Launcher - Google Play

Pick your style.

(Click on links to see demo videos)

• TREK: Total Interface
• TREK: Total Interface (Large) – for people without good vision on nimble fingers
• TREK: Trek Total Launcher Theme (+ TREK: Launcher to unlock the icons and extra content) * New Trek style

For more complete immersion, you can add the notification sounds, and matching dialer/SMS/notes apps. It is worth noting that my apps are only available for Android.

Besides wallpaper IOS does not allow for changing of the home screen, icons, or even support widgets. I could make some other apps for IOS, but I find Apple’s imposed limits and app store policies/practices too repressive.

Not Just For Phones…

Both versions of the Total Interface Large and Regular are updated to now fully support the Fold models. Next I’ll get to the New Trek version. pic.twitter.com/jLovtw1ny0 — NSTEnterprises (@TREK_Apps) April 25, 2022

📷 star-trek-technology: LCARS navigation system for cars (Android base) #Star Trek https://t.co/au9rM7DGsi Thankful for the share, feeling proud of my work, and glad people are enjoying… https://t.co/m1uJk30ETc — NSTEnterprises (@TREK_Apps) September 12, 2021

What’s Coming In The Future

The soonest thing I have coming up is another Total Launcher theme. I’ve been talking with Andrew Jarvis (the designer of the Star Trek: Picard LCARS).

He has given me some of his work and input on his vision of how to use the colours and lots of other tips for perfecting it. He will collaborate with me giving me feedback and some materials, of course without violating the contract or sharing anything owned by Paramount/CBS.

Andrew Jarvis did a fantastic job with updating LCARS and is happy to have fans enjoy it. If it’s popular, more components may follow. This will be similar to my prior collaboration with Scott Nakada, the very talented designer of the updated LCARS for the fan film Star Trek: Renegades .

It’s obvious in the app descriptions, but I’ll mention it here as well, my apps are not official or licenced. They are fan-made at a perfectionist level that doesn’t exist even in licenced apps. I don’t use any trademarks, logos, or registered intellectual property.

Of course, not using trademarked names is also why I have trouble being discovered. Perhaps many of you had an app before that used properties like those that were eventually removed and you lost your purchase because the developer didn’t know any better.

Bad apps can survive the Play Store for many years though because nobody with a licence sees them as competition to complain to CBS and have them removed.

My apps are a parody. As you see in their descriptions, I roast them a little about how I make complete gibberish sci-fi interfaces actually functional and useful. It actually is like some opposite parody where the interfaces seem to make themselves look stupid, then I make them smart. (This freedom of speech is also important to the existence of my apps.)

Well, that’s it. I hope you enjoy and share my apps. Most things have directions or a FAQ in the description, but I’m always available for support at [email protected]

Please also follow my Facebook page for chances to vote on upcoming apps, their appearance, and learn when they become available: https://www.facebook.com/Not.Star.Trek.LCARS.Apps/

What is 'LCARS'?

LCARS (pronounced elkarz) is an acronym for Library Computer Access/Retrieval System. LCARS was the fictional computer operating system on many Star Trek series beginning with The Next Generation. The LCARS graphical interface was designed by graphic designer and ST:TNG scenic art supervisor Michael Okuda.
