In this thesis, a comparison of the body SAR value of five planar WLAN antennas including two coupled-fed shorted monopole antennas, a coupled-fed loop antenna, a monopole antenna, and a monopole slot antenna for tablet PC applications are presented. A required minimum distance between the antenna and the testing flat phantom to meet the 1-g body SAR requirement of 1.6 W/kg has been determined. Results show that the body SAR results of the coupled-fed loop antenna are lowest among the five tested antennas. Detailed results and discussion are presented in this thesis. Also, a comparison of the body SAR value of a planar antenna and an antenna with 3-D bent structure are presented.

The aim of this thesis is to assess potential environmental impacts of electronic media distribution and consumption—from a life cycle perspective—as compared to those of print media. The thesis consists of a cover essay and two papers appended at the end of the thesis. The cover essay summarizes the papers and puts them in context. The main objectives of the thesis are twofold: to assess potential environmental impacts of production and consumption of tablet editions of magazines from a life cycle perspective (Paper I), and to compare potential environmental impacts of a magazine’s print edition with that of its tablet edition (Paper II). The thesis examines the following specific research questions: (1) What are the main environmental impacts of print and tablet editions? (2) Which activities are giving rise to the main environmental impacts of the print and tablet editions? (3) What are the key factors influencing these impacts? (4) What are major data gaps and uncertainties? Based on the present assessment, it is clear that for the print magazine, pulp and paper production is the principal cause of most of the potential environmental impacts. For this reason, the use of recycled paper, rather than virgin fiber, in newsprint production may considerably offset environmental impacts. For the tablet edition, the content production dominates the potential environmental impacts when readers are few. This appears to be the case in an emerging state of the magazine, but with distribution of more media products to smaller groups of people, this may persist for “mature” products as well. As the number of tablet readers grows, more of the environmental impact of the is due to manufacturing of the device and electronic distribution. However, content production may still be a major factor, depending on the specific environmental impacts studied. / <p>QC 20130306</p>

This thesis introduces BodyScape, a body-centric framework that accounts for how users coordinate their movements within and across their own limbs in order to interact with a wide range of devices, across multiple surfaces. It introduces a graphical notation that describes interaction techniques in terms of (1) motor assemblies responsible for performing a control task (input motor assembly) or bringing the body into a position to visually perceive output (output motor assembly), and (2) the movement coordination of motor assemblies, relative to the body or fixed in the world, with respect to the interactive environment. This thesis applies BodyScape to 1) investigate the role of support in a set of novel bimanual interaction techniques for hand-held devices, 2) analyze the competing effect across multiple input movements, and 3) compare twelve pan-and-zoom techniques on a wall-sized display to determine the roles of guidance and interference on performance. Using BodyScape to characterize interaction clarifies the role of device support on the user's balance and subsequent comfort and performance. It allows designers to identify situations in which multiple body movements interfere with each other, with a corresponding decrease in performance. Finally, it highlights the trade-offs among different combinations of techniques, enabling the analysis and generation of a variety of multi-surface interaction techniques. I argue that including a body-centric perspective when defining interaction techniques is essential for addressing the combinatorial explosion of interactive devices in multi-surface environments.

Examensarbetets syfte har varit att bidra med kunskap kring vilka faktorer som styr valet av applikationer för undervisning i förskolan. Syftet har också varit att uppmärksamma vilka applikationer som används i undervisning på kommunala förskoleavdelningar. Kanonforskning utgör de teoretiska utgångspunkterna och bidrar i studien med en begreppsapparat för urvalsprocesser samt urval och ligger till grund för valet av enkät som metod. 39 förskoleavdelningar från 8 kommuner har besvarat enkäten. Enkätsvaren har kompletterats genom ytterligare datainsamling kring de namngivna applikationernas upphovsmän och genom sökning på applikationer i forskningsdatabaser. Resultatet visar att det finns ett brett urval av applikationer som används i förskoleundervisning och att ett fåtal applikationer förekommer i större utsträckning än andra. Resultatet visar också att det finns flera faktorer som påverkar förskoleavdelningarnas val av applikationer. Bland dessa påverkansfaktorer finns ekonomiska resurser, val av operativsystem och personalens värderingar av vad som utgör en pedagogiskt användbar applikation representerade. Slutsatser som dras av studien är att det i stort sett är ett varierat urval av applikationer som används i förskoleundervisningen, men att det på lokal nivå förekommer en selektiv kanon, där en specifik IKT-grupp har inflytande över vilka applikationer som skattas högt. Ytterligare slutsatser som dras är att trots att personalen kommer i kontakt med applikationer via många olika källor så finns det krav som varierar från avdelning till avdelning angående vilka applikationer som kan installeras.

Die zunehmende Nutzung [1] persönlicher mobiler Geräte durch immer mehr Fahrgäste des öffentlichen Personenverkehrs (ÖPV) begünstigt die Entwicklung neuer Applikationen, die den allgegenwärtigen Zugriff auf domänenspezifische Inhalte und Echtzeitdaten über variable Schnittstellen und Informationskanäle realisieren. Near Field Communication (NFC) gilt in diesem Zusammenhang als eine vielversprechende Technologie, die neben kontaktloser Datenübertragung auch Bezahlvorgänge direkt über das mobile Endgerät ermöglicht. Mit Blick auf die unterschiedlichen Einsatzmöglichkeiten von NFC in der mobilen Reisebegleitung wird in diesem Beitrag eine ikonografische Klassifikation für die visualisierte Analyse von Anwendungsszenarien vorgestellt, welche zur Planung ubiquitärer Applikationen im ÖPV eingesetzt werden kann.

Cette thèse présente BodyScape, un espace de conception prenant en compte l’engagement corporel de l’utilisateur dans l’interaction. BodyScape décrit la façon dont les utilisateurs coordonnent les mouvements de, et entre leurs membres, lorsqu’ils interagissent avec divers dispositifs d’entrée et entre plusieurs surfaces d’affichage. Il introduit une notation graphique pour l’analyse des techniques d’interaction en termes (1) d’assemblages de moteurs, qui accomplissent une tâche d’interaction atomique (assemblages de moteurs d’entrée), ou qui positionnent le corps pour percevoir les sorties du système (assemblages de moteurs de sortie); (2) de coordination des mouvements de ces assemblages de moteurs, relativement au corps de l’utilisateur ou à son environnement interactif.Nous avons appliqué BodyScape à : 1) la caractérisation du rôle du support dans l’étude de nouvelles interactions bimanuelles pour dispositifs mobiles; 2) l’analyse des effets de mouvements concurrents lorsque l’interaction et son support impliquent le même membre; et 3) la comparaison de douze techniques d’interaction multi-échelle afin d’évaluer le rôle du guidage et des interférences sur la performance.La caractérisation des interaction avec BodyScape clarifie le rôle du support des dispositifs d’interaction sur l’équilibre de l’utilisateur, et donc sur le confort d’utilisation et la performance qui en découlent. L’espace de conception permet aussi aux concepteurs d’interactions d’identifier des situations dans lesquelles des mouvements peuvent interférer entre eux et donc diminuer performance et confort. Enfin, BodyScape révèle les compromis à considérer a priori lors de la combinaison de plusieurs techniques d’interaction, permettant l’analyse et la génération de techniques d’interaction variées pour les environnements multi-surfaces.Plus généralement, cette thèse défend l’idée qu’en adoptant une approche centrée sur les fonctions corporelles engagées au cours de l’interaction, il est possible de maîtriser la complexité de la conception de techniques d’interaction dans les environnements multi-surfaces, mais aussi dans un cadre plus général. / This thesis introduces BodyScape, a body-centric framework that accounts for how users coordinate their movements within and across their own limbs in order to interact with a wide range of devices, across multiple surfaces.
