Journal articles on the topic 'Lightsabers'

Most computational story generation systems lack the ability to generate new types of imaginary objects that play functional roles in stories, such as lightsabers in Star Wars. We present an algorithm that generates such imaginary objects, which we call gadgets, in order to extend the ontological expressivity of existing, planning-based story generation systems. The behavior of a gadget is represented as a plan including typical events that happen when the gadget is used. Our algorithm creates gadgets by extrapolating and merging one or more commonly known objects in order to achieve a narrative goal provided by an existing story generator. We extend partial-order planning to establish open conditions based on analogies between concepts related respectively to common objects and the gadget. We show the algorithm is capable of generating gadgets created by human.

In the “Star Wars” movies, Jedi knights engage in dazzling duels with lightsabers that confine light and push it against each other. However, confining photons or enabling their interaction in reality, especially in free space, is extremely challenging. Photon-photon interactions, which are only possible through optical nonlinearity, are difficult to achieve with conventional materials. The quest to confine photons in a specific space for as long as possible, and to allow individual photons to interact with each other, is a major challenge for researchers in physics and optics. Since the invention of the laser, the study of optical nonlinearity has been the foundation of various modern scientific and technological advances that contribute significantly to our daily lives. Recently, optical nonlinearity has become a central platform for quantum information, computing, and sensing research, highlighting its growing importance. This article discusses a new turning point in optical nonlinearity based on micro-resonators, and presents efforts and future perspectives to realize photon-photon interactions.

The suspended test masses of gravitational-wave (GW) detectors require precise alignment to be able to operate the detector stably and with high sensitivity. This includes the continuous counter-acting of seismic disturbances, which, below a few Hertz, are not sufficiently reduced by the seismic isolation system. The residual angular motion of suspended test masses is further suppressed by the Angular Sensing and Control (ASC) system. However, in doing so, the angular motion can be enhanced by the ASC at higher frequencies where the seismic isolation system is very effective. This has led to sensitivity limitations between about 10 Hz and 25 Hz of the LIGO detectors in past observation runs. The observed ASC noise was larger than simple models predict, which means that more accurate detector models and new simulation tools are required. In this article, we present Lightsaber, a new time-domain simulator of the ASC in LIGO. Lightsaber is a nonlinear simulation of the optomechanical system consisting of the high-power cavity laser beam and the last two stages of suspension in LIGO including the ASC. The main noise inputs are power fluctuations of the laser beam at the input of the arm cavities, read-out noise of sensors used for the ASC, displacement noise from the suspension platforms, and noise introduced by the suspension damping loops. While the plant simulation uses local degrees of freedom of individual suspension systems, the control is applied on a global angular basis, which requires a conversion between the local and global bases for sensing and actuation. Some of the studies that can be done with this simulation concern mis-centering of the beam-spot (BS) position on the test masses, the role of laser power fluctuations for angular dynamics, and the role of the various nonlinear dynamics. The next important step following this work will be a detailed comparison between Lightsaber results and data from the control channels of the LIGO detectors.

Humans have been using stories to entertain, educate, and persuade audiences for centuries. The advent of modern AI tools in the form of Large Language Models (LLMs) such as chatGPT continues to fulfill this purpose. However while recent work has shown that LLMs can successfully be used for narrative generation, they lack coherence and can be prone to repetition and stilted language. Automated Planning can therefore be combined with Natural Language text generation to create narratives (stories) that are logical, coherent, and believable. A planning model provides scaffolding to an LLM so that the LLM's language generation is context-dependent, in order to allow users to create more coherent, logical, and believable stories in a variety of domains.

In three experiments with U.S. undergraduates, effects of three levels of naturally mapped control interfaces were compared on a player's sense of presence, interactivity, realism, and enjoyment in video games. The three levels of naturally mapped control interfaces were: kinesic natural mapping (using the player's body as a game controller), incomplete tangible mapping (using a controller in a way similar to a real object), and realistic tangible mapping (using a controller or an object that directly relates to the real-life activity the game simulates). The results show that levels of interactivity, realism, spatial presence, and enjoyment were consistent across all conditions. However, when performing activities such as table tennis or lightsaber dueling with objects in-hand (incomplete tangible or realistic tangible conditions), perceived reality was a more important predictor of spatial presence. When performing the same activities with empty hands, interactivity emerged as the more important direct predictor of spatial presence. Control interface, therefore, matters greatly to the route by which cognitive processing of games takes place and how enjoyment is produced.

This study - Making the Fantastic Real - provides research into the subject of design fiction, science fiction fandom, sharable digital media content on the one hand, and the design of real-life engineering artifacts on the other. This study has selected the case of The Hacksmith to understand the space of meaning (science, fiction, co-creation, and design) created by the production of “the fantastic” by this specific acknowledged Canadian Youtuber. The Hacksmith Industries is the trademark name of the YouTube channel The Hacksmith (https://www.youtube.com/c/theHacksmith/featured) created by Canadian engineer James Hobson in 2006. One of the signature elements of Hobson’s interests is the lightsaber and the Star Wars franchise. But Hobson explores many other dimensions of popular culture, ranging from nerf wars shooters to superhero artifacts of the Marvel Cinematic Universe. His focus is on how to make elements or objects of the fantastic real, as his slogan goes, not to change any storyline, story arc or franchise world, but to see how far the innate human capability of play and creation can be taken from the fictional realm to reality.

Abstract Since George Lucas’s film A New Hope was first screened in 1977, the Star Wars saga has become a pop-culture phenomenon incorporating films, videogames, books, merchandise, and a quasi-religious philosophy, but linguistic research on Star Wars is scarce and has mainly focused on language use in the films. There is as yet no investigation of the impact of Star Wars on the English language, and the present study fills this gap using corpus-linguistic methods to investigate the extent to which characteristic words and constructions from the Star Wars universe have become established in English. Five Star Wars-derived items included in the Oxford English Dictionary (OED), namely Jedi, Padawan, lightsabre (with spelling variants), Yoda, and the characteristic construction to the dark side were analysed regarding their frequency of occurrence in four corpora of present-day English (COCA, COHA, BNC, BNC Spoken 2014) and coded regarding their level of independence from the original films. The results show that over one-third of the uses of the investigated Star Wars-derived items are innovative (like the BNC example Other imbibers have gone over to the dark side of beer, rejecting the pasteurised lager produced by the breweries) and thus well integrated into the English language.

IntroductionThe Internet (especially in the so-called Web 2.0 phase), digital media and file-sharing networks have thrust copyright law under public scrutiny, provoking discourses questioning what is fair in the digital age. Accessible hardware and software has led to prosumerism – creativity blending media consumption with media production to create new works that are freely disseminated online via popular video-sharing Web sites such as YouTube or genre specific music sites like GYBO (“Get Your Bootleg On”) amongst many others. The term “prosumer” is older than the Web, and the conceptual convergence of producer and consumer roles is certainly not new, for “at electric speeds the consumer becomes producer as the public becomes participant role player” (McLuhan 4). Similarly, Toffler’s “Third Wave” challenges “old power relationships” and promises to “heal the historic breach between producer and consumer, giving rise to the ‘prosumer’ economics” (27). Prosumption blurs the traditionally separate consumer and producer creating a new creative era of mass customisation of artefacts culled from the (copyrighted) media landscape (Tapscott 62-3). Simultaneously, corporate interests dependent upon the protections provided by copyright law lobby for augmented rights and actively defend their intellectual property through law suits, takedown notices and technological reinforcement. Despite a lack demonstrable economic harm in many cases, the propertarian approach is winning and frequently leading to absurd results (Collins).The balance between private and public interests in creative works is facilitated by the doctrine of fair use (as codified in the United States Copyright Act 1976, section 107). The majority of copyright laws contain “fair” exceptions to claims of infringement, but fair use is characterised by a flexible, open-ended approach that allows the law to flex with the times. Until recently the defence was unique to the U.S., but on 2 January Israel amended its copyright laws to include a fair use defence. (For an overview of the new Israeli fair use exception, see Efroni.) Despite its flexibility, fair use has been systematically eroded by ever encroaching copyrights. This paper argues that copyright enforcement has spun out of control and the raison d’être of the law has shifted from being “an engine of free expression” (Harper & Row, Publishers, Inc. v. Nation Enterprises 471 U.S. 539, 558 (1985)) towards a “legal regime for intellectual property that increasingly looks like the law of real property, or more properly an idealized construct of that law, one in which courts seeks out and punish virtually any use of an intellectual property right by another” (Lemley 1032). Although the copyright landscape appears bleak, two recent cases suggest that fair use has not fallen by the wayside and may well recover. This paper situates fair use as an essential legal and cultural mechanism for optimising creative expression.A Brief History of CopyrightThe law of copyright extends back to eighteenth century England when the Statute of Anne (1710) was enacted. Whilst the length of this paper precludes an in depth analysis of the law and its export to the U.S., it is important to stress the goals of copyright. “Copyright in the American tradition was not meant to be a “property right” as the public generally understands property. It was originally a narrow federal policy that granted a limited trade monopoly in exchange for universal use and access” (Vaidhyanathan 11). Copyright was designed as a right limited in scope and duration to ensure that culturally important creative works were not the victims of monopolies and were free (as later mandated in the U.S. Constitution) “to promote the progress.” During the 18th century English copyright discourse Lord Camden warned against propertarian approaches lest “all our learning will be locked up in the hands of the Tonsons and the Lintons of the age, who will set what price upon it their avarice chooses to demand, till the public become as much their slaves, as their own hackney compilers are” (Donaldson v. Becket 17 Cobbett Parliamentary History, col. 1000). Camden’s sentiments found favour in subsequent years with members of the North American judiciary reiterating that copyright was a limited right in the interests of society—the law’s primary beneficiary (see for example, Wheaton v. Peters 33 US 591 [1834]; Fox Film Corporation v. Doyal 286 US 123 [1932]; US v. Paramount Pictures 334 US 131 [1948]; Mazer v. Stein 347 US 201, 219 [1954]; Twentieth Century Music Corp. v. Aitken 422 U.S. 151 [1975]; Aronson v. Quick Point Pencil Co. 440 US 257 [1979]; Dowling v. United States 473 US 207 [1985]; Harper & Row, Publishers, Inc. v. Nation Enterprises 471 U.S. 539 [1985]; Luther R. Campbell a.k.a. Luke Skyywalker, et al. v. Acuff-Rose Music, Inc. 510 U.S 569 [1994]). Putting the “Fair” in Fair UseIn Folsom v. Marsh 9 F. Cas. 342 (C.C.D. Mass. 1841) (No. 4,901) Justice Storey formulated the modern shape of fair use from a wealth of case law extending back to 1740 and across the Atlantic. Over the course of one hundred years the English judiciary developed a relatively cohesive set of principles governing the use of a first author’s work by a subsequent author without consent. Storey’s synthesis of these principles proved so comprehensive that later English courts would look to his decision for guidance (Scott v. Stanford L.R. 3 Eq. 718, 722 (1867)). Patry explains fair use as integral to the social utility of copyright to “encourage. . . learned men to compose and write useful books” by allowing a second author to use, under certain circumstances, a portion of a prior author’s work, where the second author would himself produce a work promoting the goals of copyright (Patry 4-5).Fair use is a safety valve on copyright law to prevent oppressive monopolies, but some scholars suggest that fair use is less a defence and more a right that subordinates copyrights. Lange and Lange Anderson argue that the doctrine is not fundamentally about copyright or a system of property, but is rather concerned with the recognition of the public domain and its preservation from the ever encroaching advances of copyright (2001). Fair use should not be understood as subordinate to the exclusive rights of copyright owners. Rather, as Lange and Lange Anderson claim, the doctrine should stand in the superior position: the complete spectrum of ownership through copyright can only be determined pursuant to a consideration of what is required by fair use (Lange and Lange Anderson 19). The language of section 107 suggests that fair use is not subordinate to the bundle of rights enjoyed by copyright ownership: “Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work . . . is not an infringement of copyright” (Copyright Act 1976, s.107). Fair use is not merely about the marketplace for copyright works; it is concerned with what Weinreb refers to as “a community’s established practices and understandings” (1151-2). This argument boldly suggests that judicial application of fair use has consistently erred through subordinating the doctrine to copyright and considering simply the effect of the appropriation on the market place for the original work.The emphasis on economic factors has led courts to sympathise with copyright owners leading to a propertarian or Blackstonian approach to copyright (Collins; Travis) propagating the myth that any use of copyrighted materials must be licensed. Law and media reports alike are potted with examples. For example, in Bridgeport Music, Inc., et al v. Dimension Films et al 383 F. 3d 400 (6th Cir. 2004) a Sixth Circuit Court of Appeals held that the transformative use of a three-note guitar sample infringed copyrights and that musicians must obtain licence from copyright owners for every appropriated audio fragment regardless of duration or recognisability. Similarly, in 2006 Christopher Knight self-produced a one-minute television advertisement to support his campaign to be elected to the board of education for Rockingham County, North Carolina. As a fan of Star Wars, Knight used a makeshift Death Star and lightsaber in his clip, capitalising on the imagery of the Jedi Knight opposing the oppressive regime of the Empire to protect the people. According to an interview in The Register the advertisement was well received by local audiences prompting Knight to upload it to his YouTube channel. Several months later, Knight’s clip appeared on Web Junk 2.0, a cable show broadcast by VH1, a channel owned by media conglomerate Viacom. Although his permission was not sought, Knight was pleased with the exposure, after all “how often does a local school board ad wind up on VH1?” (Metz). Uploading the segment of Web Junk 2.0 featuring the advertisement to YouTube, however, led Viacom to quickly issue a take-down notice citing copyright infringement. Knight expressed his confusion at the apparent unfairness of the situation: “Viacom says that I can’t use my clip showing my commercial, claiming copy infringement? As we say in the South, that’s ass-backwards” (Metz).The current state of copyright law is, as Patry says, “depressing”:We are well past the healthy dose stage and into the serious illness stage ... things are getting worse, not better. Copyright law has abandoned its reason for being: to encourage learning and the creation of new works. Instead, its principal functions now are to preserve existing failed business models, to suppress new business models and technologies, and to obtain, if possible, enormous windfall profits from activity that not only causes no harm, but which is beneficial to copyright owners. Like Humpty-Dumpty, the copyright law we used to know can never be put back together.The erosion of fair use by encroaching private interests represented by copyrights has led to strong critiques leveled at the judiciary and legislators by Lessig, McLeod and Vaidhyanathan. “Free culture” proponents warn that an overly strict copyright regime unbalanced by an equally prevalent fair use doctrine is dangerous to creativity, innovation, culture and democracy. After all, “few, if any, things ... are strictly original throughout. Every book in literature, science and art, borrows, and must necessarily borrow, and use much which was well known and used before. No man creates a new language for himself, at least if he be a wise man, in writing a book. He contents himself with the use of language already known and used and understood by others” (Emerson v. Davis, 8 F. Cas. 615, 619 (No. 4,436) (CCD Mass. 1845), qted in Campbell v. Acuff-Rose, 62 U.S.L.W. at 4171 (1994)). The rise of the Web 2.0 phase with its emphasis on end-user created content has led to an unrelenting wave of creativity, and much of it incorporates or “mashes up” copyright material. As Negativland observes, free appropriation is “inevitable when a population bombarded with electronic media meets the hardware [and software] that encourages them to capture it” and creatively express themselves through appropriated media forms (251). The current state of copyright and fair use is bleak, but not beyond recovery. Two recent cases suggest a resurgence of the ideology underpinning the doctrine of fair use and the role played by copyright.Let’s Go CrazyIn “Let’s Go Crazy #1” on YouTube, Holden Lenz (then eighteen months old) is caught bopping to a barely recognizable recording of Prince’s “Let’s Go Crazy” in his mother’s Pennsylvanian kitchen. The twenty-nine second long video was viewed a mere twenty-eight times by family and friends before Stephanie Lenz received an email from YouTube informing her of its compliance with a Digital Millennium Copyright Act (DMCA) take-down notice issued by Universal, copyright owners of Prince’s recording (McDonald). Lenz has since filed a counterclaim against Universal and YouTube has reinstated the video. Ironically, the media exposure surrounding Lenz’s situation has led to the video being viewed 633,560 times at the time of writing. Comments associated with the video indicate a less than reverential opinion of Prince and Universal and support the fairness of using the song. On 8 Aug. 2008 a Californian District Court denied Universal’s motion to dismiss Lenz’s counterclaim. The question at the centre of the court judgment was whether copyright owners should consider “the fair use doctrine in formulating a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law.” The court ultimately found in favour of Lenz and also reaffirmed the position of fair use in relation to copyright. Universal rested its argument on two key points. First, that copyright owners cannot be expected to consider fair use prior to issuing takedown notices because fair use is a defence, invoked after the act rather than a use authorized by the copyright owner or the law. Second, because the DMCA does not mention fair use, then there should be no requirement to consider it, or at the very least, it should not be considered until it is raised in legal defence.In rejecting both arguments the court accepted Lenz’s argument that fair use is an authorised use of copyrighted materials because the doctrine of fair use is embedded into the Copyright Act 1976. The court substantiated the point by emphasising the language of section 107. Although fair use is absent from the DMCA, the court reiterated that it is part of the Copyright Act and that “notwithstanding the provisions of sections 106 and 106A” a fair use “is not an infringement of copyright” (s.107, Copyright Act 1976). Overzealous rights holders frequently abuse the DMCA as a means to quash all use of copyrighted materials without considering fair use. This decision reaffirms that fair use “should not be considered a bizarre, occasionally tolerated departure from the grand conception of the copyright design” but something that it is integral to the constitution of copyright law and essential in ensuring that copyright’s goals can be fulfilled (Leval 1100). Unlicensed musical sampling has never fared well in the courtroom. Three decades of rejection and admonishment by judges culminated in Bridgeport Music, Inc., et al v. Dimension Films et al 383 F. 3d 400 (6th Cir. 2004): “Get a license or do not sample. We do not see this stifling creativity in any significant way” was the ruling on an action brought against an unlicensed use of a three-note guitar sample under section 114, an audio piracy provision. The Bridgeport decision sounded a death knell for unlicensed sampling, ensuring that only artists with sufficient capital to pay the piper could legitimately be creative with the wealth of recorded music available. The cost of licensing samples can often outweigh the creative merit of the act itself as discussed by McLeod (86) and Beaujon (25). In August 2008 the Supreme Court of New York heard EMI v. Premise Media in which EMI sought an injunction against an unlicensed fifteen second excerpt of John Lennon’s “Imagine” featured in Expelled: No Intelligence Allowed, a controversial documentary canvassing alleged chilling of intelligent design proponents in academic circles. (The family of John Lennon and EMI had previously failed to persuade a Manhattan federal court in a similar action.) The court upheld Premise Media’s arguments for fair use and rejected the Bridgeport approach on which EMI had rested its entire complaint. Justice Lowe criticised the Bridgeport court for its failure to examine the legislative intent of section 114 suggesting that courts should look to the black letter of the law rather than blindly accept propertarian arguments. This decision is of particular importance because it establishes that fair use applies to unlicensed use of sound recordings and re-establishes de minimis use.ConclusionThis paper was partly inspired by the final entry on eminent copyright scholar William Patry’s personal copyright law blog (1 Aug. 2008). A copyright lawyer for over 25 years, Patry articulated his belief that copyright law has swung too far away from its initial objectives and that balance could never be restored. The two cases presented in this paper demonstrate that fair use – and therefore balance – can be recovered in copyright. The federal Supreme Court and lower courts have stressed that copyright was intended to promote creativity and have upheld the fair doctrine, but in order for the balance to exist in copyright law, cases must come before the courts; copyright myth must be challenged. As McLeod states, “the real-world problems occur when institutions that actually have the resources to defend themselves against unwarranted or frivolous lawsuits choose to take the safe route, thus eroding fair use”(146-7).
