PADDs were used by such space-faring organizations as Starfleet, the Andorian Imperial Guard, Bajoran Militia, Cardassian Union, Klingon Empire, Romulan Star Empire, and Vulcan High Command. They were common to cultures even as distant as the Delta Quadrant.
General Specifications Edit
Consisting of a large touchscreen display and minimalistic manual interface or control panel (generally only one or two buttons), the typical PADD is used for a variety of functions including logging manifests, compiling duty rosters or diagnostic reports, entering personal data, and/or accessing library computer systems using the LCARS Interface.
Varying in size, shape and specification, PADDs are often distinguished by the species of their manufacturer or user. United Earth and Federation Starfleet PADDs were generally flat and rectangular in shape, while Klingon and Cardassian PADDs were often more angular.
Standard issue during the 22nd century, PADDs utilized by Starfleet were rectangular in shape, dominated by a large display screen taking up much of the surface area of the device. Small buttons were located just below the screen, most often grouped in two, at the lower right-hand side of the interface. Varying control button arrangements were also in use. (ENT: "Vox Sola", "Dead Stop")
These PADDs were often used to display schematics, or subspace transmissions and were capable of wireless computer networking as well as playing movies, recording logs and audio playback. (ENT: "Breaking the Ice", "Dawn", "Twilight")
At some point between 2144 and 2154, Arik Soong was able to open all the locks in the San Francisco prison he was being held at using just a PADD. After this incident, he was only allowed to use paper when sketching and writing his ideas. (ENT: "Borderland")
One of the most often used devices employed by personnel serving in Starfleet, PADDs were common aboard Federation starships, space stations, and planetary facilities during the 23rd and 24th centuries.
First appearing as late as 2266 aboard such starship types as the Constitution-class vessel, PADDs of the 2260s were large, wedge-shaped devices, operated almost exclusively through the use of a stylus. These data PADDs were often carried by yeomen aboard starships, but appeared in other locations including Starfleet's Starbase 11. (TOS: "The Man Trap", "The Menagerie, Part I", "The Menagerie, Part II"; DS9: "Trials and Tribble-ations")
By 2364, PADDs had taken on a smaller profile and, while some models would include one, the stylus was replaced by simple, touch-sensitive controls, generally located beneath a small, square-shaped display screen. Generally small and light-weight, the PADDs of the 2360s and 2370s were basically rectangular in shape, but varied in size, proportion, and even color – ranging from gray and muted blue colors, to red. Some PADDs, like the one used by Dr. Lewis Zimmerman aboard Jupiter Station in 2376, were translucent. (TNG: "Encounter at Farpoint"; DS9: "Emissary"; VOY: "Caretaker", "Life Line", et al.) When struck with enough force, the screen of a PADD could be shattered resulting in shards sharp enough to cut Human skin. (DS9: "Statistical Probabilities")
While the common function of these Federation PADDs was most often straight forward data entry or data retrieval, some PADDs were capable of more artistic tasks. Some PADDs, often larger in size than most of their counterparts, were used to draw up schematics or to create composite images or artwork. PADDs were also capable of predictive text functions, allowing users to enter a small amount of data to achieve full words or even sentences. In addition, a stylus could be used for text entry. PADDs could also order a site-to-site transport. (DS9: "Babel", "The House of Quark", "The Muse", "Image in the Sand", VOY: "Renaissance Man")
Andorian Imperial GuardEdit
Roughly the same size as their Earth Starfleet counterparts, PADDs used by officers in the service of the Andorian Imperial Guard were rectangular in shape, highlighted by several square-shaped pieces at the sides and top which itself was rounded.
In use during the 24th century aboard Bajoran spacecraft and stations (including New Bajor and starbase Deep Space 9), Bajoran PADDs were small, roughly oval-shaped devices, nearly the same size as (though slimmer than) the small Federation PADD variant.
Capable of the same general function as their alien counterparts, Bajoran PADDs could be used to download information from primary computer sources, including text documents as large as novels. They were also able to display information in Bajoran as well as other languages. (DS9: "Emissary", "The Jem'Hadar", "Shadows and Symbols")
Consisting of a brown and gold-colored unit, the Cardassian PADD was angular and irregularly shaped, featuring an oval-shaped display screen and a number of trapezoidal and irregularly shaped buttons.
A mainstay in business dealings involving Ferengi in and outside of the Ferengi Alliance, Ferengi PADDs were often elongated-hexagonally-shaped units. Muted gold in color, these PADDs featured a number of button controls and a hexagon-shaped viewscreen often displaying the familiar circular Ferengi interface layout.
Capable of cataloging inventory, inputting vouchers, or drawing up business plans, Ferengi PADDs were most often geared toward business and profit. Chief amongst their capabilities was currency transfer, allowing transactions to take place with simple thumb print verification. These PADDs were utilized by Ferengi Commerce Authority liquidators and could be found at the Tower of Commerce on Ferenginar, as well as aboard Ferengi vessels like Nunk's Marauder and at Quark's on Deep Space 9. (TNG: "Firstborn"; DS9: "The Wire", "Family Business", "The Begotten", "Profit and Lace"; VOY: "Inside Man")
At least two models of data PADDs were used by warriors in the service of the Klingon Defense Force during the 24th century.
Both harshly angular compared to their Federation counterparts, Klingon PADDs came in hand-held and larger, landscape-style varieties. Both displaying information in Klingonese, these PADDs could be found in the chambers of the Klingon High Council on Qo'noS as well as aboard Klingon vessels such as the IKS Rotarran.
The smaller model was dark green in color and featured several button controls running up the center of the device to a rectangular-shaped display screen capable of recorded-video playback. The larger model was brown and was held horizontally with a handle attached to the left of an angular, touch screen display. (DS9: "The House of Quark", "Blaze of Glory", "Soldiers of the Empire", "Tacking Into the Wind")
Golden-brown in color, these PADDs were roughly the same size as their Alpha/Beta Quadrant counterparts, but featured circular display screens with several button controls below. Among their functions, they were used to display missing persons reports. (VOY: "Workforce", "Workforce, Part II")
Background information Edit
The PADDs seen from TNG onwards were conceived and designed by Rick Sternbach, who has submitted the first version of the design in January 1987. He has also designed the vast majority of the variations following his first version. (Star Trek: The Magazine Volume 1, Issue 3, pp. 68-71)
Not long after their debut in TNG, PADD-like devices became a real-life technology with the introduction of the PDA's made by Palm and Apple Newton. Since then devices with touch-sensitive displays and user input systems which reconfigure themselves depending on the task at hand have become common, the most notable one being Apple's iPad, sharing a similar sounding device name.
Unlike their real world counterparts, most PADDs on TNG, DS9 and VOY were nonfunctional, rarely even incorporating lighted display screens, but rather printed "okudagrams". Lighted PADDs did eventually make their way to screens for Star Trek: Insurrection, with custom and store-bought devices like the Cabin Light Box, being used through Star Trek: First Contact and into Enterprise.
