Internet Filters: A Public Policy Report (Second edition; fully revised and updated)

No sooner was the Internet upon us than anxiety arose over the ease of accessing pornography and other controversial content. In response, entrepreneurs soon developed filtering products. By the end of the decade, a new industry had emerged to create and market Internet filters....Yet filters were highly imprecise from the beginning. The sheer size of the Internet meant that identifying potentially offensive content had to be done mechanically, by matching "key" words and phrases; hence, the blocking of Web sites for "Middlesex County," or words such as "magna cum laude". Internet filters are crude and error-prone because they categorize expression without regard to its context, meaning, and value. Yet these sweeping censorship tools are now widely used in companies, homes, schools, and libraries. Internet filters remain a pressing public policy issue to all those concerned about free expression, education, culture, and democracy. This fully revised and updated report surveys tests and studies of Internet filtering products from the mid-1990s through 2006. It provides an essential resource for the ongoing debate

Design Concepts for Automating Maintenance Instructions

This research task was performed under the Technology for Readiness and Sustainment (TRS) contract (F33615-99-D-6001) for the Air Force Research Laboratory (AFRL), Sustainment Logistics Branch (HESS) at Wright-Patterson AFB, OH. The period of performance spanned one year starting 29 January 1999. The objective of this task was to develop and demonstrate a framework that can support the automated validation and verification of aircraft maintenance Technical Orders (TOs). The research team examined all stages ofTO generation to determine which tasks most warranted further research. From that investigation, validation and verification of appropriate, safe, and correct procedure steps emerged as the primary research target. This process would be based on available computer-aided design (CAD) data, procedure step ordering from existing sources, and human models. This determination was based on which tasks could yield the greatest impact on the authoring process and offer the greatest potential economic benefits. The team then developed a research roadmap and outlined specific technologies to be addressed in possible subsequent Air Force research tasks. To focus on the potential technology integration of the validation and verification component into existing or future TO generation procedures, we defined a demonstration scenario. Using the Front Uplock Hook assembly from an F/A-18 as the subject, we examined task procedure steps and failures that could be exposed by automated validation tools. These included hazards to personnel, damage to equipment, and incorrect disassembly order. Using the Parameterized Action Representation (PAR) developed on previous projects for actions and equipment behaviors, we characterized procedure steps and their positive and negative consequences. Finally, we illustrated a hypothetical user interface extension to a typical Interactive Electronic Technical Manual (IETM) authoring system to demonstrate how this process might appear to the TO author

Nostalgia and iPhone Camera Apps: An Ethnographic Visual Approach to iPhoneography

The iPhone is the most popular smartphone and camera on social media. iPhoneography, the photography taken or edited with the iPhone, has set the trend of nostalgic photography on social media during the 2010s; thus, the iPhone, a high-tech camera, produces low-tech-looking images. This dissertation attempts to find out why iPhone photographers (iPhoneographers) take, edit, and share images that mimic photographs taken with analog photographic equipment. I argue that nostalgia allows iPhoneographers to use the iPhone as a creative tool and to belong to a community. Based on the arguments of Vilém Flusser—who suggested that photographers are more interested in the camera and the process of taking pictures than in the photographs produced—this work focuses first on the iPhone camera and the camera apps. (This work also considers the writings of Roland Barthes, Susan Sontag, and W. J. T. Mitchell, as they pertain to photography and iPhoneography.) It traces the beginning of the nostalgic photograph style to 2008, when the Apple App Store offered apps that behaved like toy cameras and rendered images similar to those produced by toy and Polaroid cameras. The Hipstamatic app set the trend in 2009, and Instagram made it mainstream. Nostalgia is more a source of inspiration and creativity than a source of melancholy and longing for the past. The iPhoneography community on Facebook tends to form small groups that share and curate specific topics, such as clouds, portraits, flowers, and images produced with Hipstamatic. A small survey of the iPhoneography community shows that the community considers iPhoneography an art

Human motion analysis and simulation tools: a survey

Computational systems to identify objects represented in image sequences and tracking their motion in a fully automatic manner, enabling a detailed analysis of the involved motion and its simulation are extremely relevant in several fields of our society. In particular, the analysis and simulation of the human motion has a wide spectrum of relevant applications with a manifest social and economic impact. In fact, usage of human motion data is fundamental in a broad number of domains (e.g.: sports, rehabilitation, robotics, surveillance, gesture-based user interfaces, etc.). Consequently, many relevant engineering software applications have been developed with the purpose of analyzing and/or simulating the human motion. This chapter presents a detailed, broad and up to date survey on motion simulation and/or analysis software packages that have been developed either by the scientific community or commercial entities. Moreover, a main contribution of this chapter is an effective framework to classify and compare motion simulation and analysis tools

Virtual library:a technical implementation for a virtual reality library interface

Abstract. Libraries, as traditional information storages, serve an important role in providing free access to civilization’s knowledge to the public. In the advent of the information society, conventional means of knowledge seeking slowly become obsolete. As technologies advance, libraries shall discover how available inventions could be utilized in enhancing library services and raising public awareness. The offer to discover Virtual Library project was given to the author by the Center for Ubiquitous Computing in the University of Oulu, with the idea originating from Oulu City Library. The goal of the project was to implement an interactive application that would provide a unique experience for library users and show off capabilities of modern virtual technologies. The requirements for it were elicited and refined in a series of participatory design workshops held in Oulu City Library, and as a result, the content of initial web prototype was utilized in the creation of standalone virtual reality application on Unreal Engine 4. The application works with Oculus Rift headset and Oculus Touch motion controllers and lets the user explore the virtual model of Oulu City Library premises as well as some fictional places, added for diverse experience, and experience several activities. Virtual Library was evaluated in a series of testing sessions held in the Oulu City Library with a total of 12 participants, which were primarily the library’s staff members. Overall, the application was positively acclaimed, providing an interesting and unusual library experience, and presenting capabilities of modern virtual reality technologies.Virtuaalikirjasto : tekninen kuvaus virtuaalitodellisuutta hyödyntävälle kirjastopalvelulle. Tiivistelmä. Kirjastoilla on perinteisesti tärkeä rooli tiedon välittäjinä ja tallentajina. Kirjastojen tulee myös mahdollistaa pääsy tiedon ääreen. Siirryttäessä lähemmäksi tietoyhteiskuntaa, perinteiset tavat käsitellä ja havainnoida tietoa ovat jäämässä historiaan. Myös kirjastot kehittyvät ja oppivat kuinka uusia teknologioita on mahdollista hyödyntää tiedon välittämisessä yhteisöille. Virtuaalikirjasto-projekti lähti Oulun kaupungin kirjaston pyynnöstä Oulun yliopiston Jokapaikan tietotekniikan tutkimusryhmälle. Projektin päämääränä oli toteuttaa interaktiivinen sovellus, joka tarjoaisi kirjaston asiakkaille elämyksellistä sisältöä samalla havainnollistaen virtuaalitodellisuuden ja siihen liittyvien teknologioiden mahdollisuuksia. Sovelluksen toteutusta hiottiin Oulun kaupunginkirjastossa sarjalla osallistavan suunnittelun mukaisia työpajoja. Virtuaalitodellisuussovellus toteutettiin Unreal Engine 4 -pelimoottorilla. Se toimii Oculus Rift -virtuaalilaseilla ja Oculus Touch -ohjaimilla. Sovelluksessa on mahdollista kulkea vapaasti virtuaalisessa Oulun kaupunginkirjastossa, sekä tilaan liitetyissä mielikuvituksellisemmissa maailmoissa. Virtuaalikirjasto-sovellus evaluoitiin Oulun kaupunginkirjastossa sarjalla käyttäjätestejä. Testikäyttäjiä oli kaikkiaan 12 ja he olivat pääosin kirjaston työntekijöitä. Sovelluksen vastaanotto oli positiivinen. Käyttäjät totesivat sen havainnollistavan käytettävissä olevan tekniikan mahdollisuuksia samalla tarjoten mielenkiintoisen ja epätavallisen kirjastokokemuksen
