The objectives and goals of this study is to analyze different styles of viewing information on mobile platforms and to find out what each different view brings to the table by creating and testing them with varied users. The study takes into account List View, Scroll View, and Grid View and compares them while viewing three different data formats. For this study, plain text, tabulated text, and interactive text will be analyzed. Smart mobile devices are the most used platform to view data in today's information rich world according to a survey conducted by Forrester Research. When designing for them, a lot must be considered but not knowing what is best suited for each application can be daunting for developers and designers, especially in the user experience context. This study aims to explore each mobile interface and give a better understanding about the different user interface designs features. Information visualization on cross-media information spaces and platforms is an important part of how information is disseminated today. Considering nowadays people get their information through multiple different media platforms like tablets, mobile phones, and web browsers, how to visualize data across all these platforms is a study to focus on in itself. The study showed that users performed better with certain views paired with different data types over others. Certain features of each view helped users understand the data types better over others while others improved users speed in reading data. Users showed certain preferences when interacting with each view on mobile devices when viewing cross media information which is mentioned in the study. / Målet för den här studien är att analysera olika sätt att visa information på mobila enheter och jämföra dessa genom att testa med olika användare. Studien undersöker de olika vyerna List View, Scroll View och Grid View och jämför dem med tre olika dataformat: vanlig text, tabellerad text och interaktiv text. Smarta mobila enheter är den mest använda plattformen för att synliggöra i dagens informationsrika samhälle enligt en undersökning av Forrester Research. När man utformar designlösningar för smarta mobila enheter är det mycket man behöver ta hänsyn till. Att inte veta vad som är bäst för varje applikation kan vara en svår uppgift för utvecklare och designers, särskilt ur användarperspektiv. Den här studiens syfte är att utforska varje mobilt gränssnitt och ge en bättre förståelse för de olika designlösningarna. Att visualisera information på olika mediers informationsytor och plattformar är en viktig del av hur information sprids idag.Om man tar i beaktan att människor numera får information via flertalet medieplattformar som tex läsplattor, mobiltelefoner, och webbläsare så inser man att visualisering av data på alla dessa medieplattformar är en studie i sig. Studien visade att användare lyckades bättre med vissa vyer och datatyper i kombination jämfört med andra. Specifika funktioner i varje vy hjälpte användare att förstå vissa datatyper bättre än andra, medan andra förbättrade användarnas snabbhet att läsa data. Användare tycktes föredra att interagera med vyer på mobila enheter när de tittade på information på olika medieplattformar, vilket nämns i studien.

Det har blivit modernt att använda mobila enheter i tidig ålder. Studien syftar till att förstå hur barn interagerar med mobila enheter under de första 4 levnadsåren och hur de kan hjälpa föräldrar att få inlärningsfördelar för de yngsta barnen. För att möta syftet med undersökningen fanns flera formulerade frågor om hur barnens utvecklingsnivå kan påverka möjligheten till interaktion och lärande med mobila enheter, vilka fördelar och nackdelar föräldrarna upptäckt under sina barns användning. Relevanta teorin presenterades om barns fysiska och kognitiva utveckling från 0 till 4 års ålder. Den blandade forskningsmetoden strategi (enkät och intervjuer) var tillräckligt effektiva för att förstå hur barnens användning av mobila enheter skiljer sig för varje år när de blir äldre. Det presenterades också några rekommendationer till föräldrarna. / It has become modern to use mobile devices at an early age. The study aims to understand the way young children interacts with mobile devices during the first 4 years of life and how mobile devices can help parents gain learning benefits for the youngest children. In order to meet the purpose of the research there were several formulated questions concerning how the stage of children’s development can affect the possibility of interaction and learning with mobile devices and what advantages and disadvantages the parents discovered during their children’s usage of mobile devices. The relevant theory was presented regarding children’s physical and cognitive development from 0 to 4 years old. The mixed method approach (survey and interviews) was effective enough to understand how the children usage of mobile devices differs from year to year as they become older. There were some recommendations for the parents that were presented as well.

Approximately 20–25 percent of the Swedish population experience difficulties with reading and writing, and 5–8 percent have dyslexia. Despite this and the widespread use of mobile phones, research on typographic design is primarily focused on the general population, creating a knowledge gap regarding how design decisions can affect individuals with dyslexia. Therefore the purpose of this study was to deepen the understanding of how different fonts and typographic elements on mobile screens affect readability for people with dyslexia. Participants were recruited from various Facebook groups using a subjective and snowball sampling method, including a group of individuals with dyslexia and a comparative control group. The survey was designed based on previous research and was conducted online, including a readability test. The readability test consisted of nine images with short texts presenting different typographic conditions, and respondents assessed the readability on a five-point scale. Subsequently, the data were processed to identify patterns and correlations. The study was based on theoretical perspectives on typography, dyslexia, and cognitive load theory. The results showed that sans-serif fonts, especially Verdana, performed bestand were considered the most readable by both respondents with and without dyslexia. Additionally, the study found that custom fonts designed for dyslexia do not necessarily improve readability. This underscores the importance of choosing simple, well-known fonts to facilitate reading for people with dyslexia. The conclusions emphasized the need to minimize cognitive load and select fonts with a simpler design to promote readability. Lastly, the study also identified increased letter spacing as a strategy to improve readability on mobile screens for people with dyslexia. / Cirka 20–25 procent av Sveriges befolkning upplever läs- och skrivsvårigheter, och 5–8procent har dyslexi. Trots detta och den breda användningen av mobiltelefoner är forskningen om typografisk design främst inriktad på den generella allmänheten, vilket skapar en kunskapslucka för hur designbeslut kan påverka personer med dyslexi. Syftet med studien är att fördjupa förståelsen för hur olika typsnitt och typografiska element på mobilskärmar påverkar läsbarheten för personer med dyslexi. Genom ett subjektivt och snöbollsurval rekryterades deltagare från olika Facebookgrupper, både personer med dyslexi och en jämförande kontrollgrupp. Enkäten utformades med hjälp av tidigare forskning och genomfördes online, vilken inkluderade ett läsbarhetstest. Läsbarhetstestet bestod av nio bilder med korta texter med olika typografiska förhållanden, där respondenterna bedömde läsbarheten på en femgradig skala. Därefter bearbetades data för att identifiera mönster och samband. Studien utgick från teoretiska perspektiv om typografi, dyslexi samt kognitiv belastningsteori. Resultaten visade att sans-serif typsnitt, särskilt Verdana, presterade bäst och ansågs vara mest lättlästa av både respondenter med och utan dyslexi. Dessutom visade studien att specialanpassade typsnitt för dyslexi inte nödvändigtvis förbättrar läsbarheten. Det understryker vikten av att välja enkla och välkända typsnitt för att underlätta läsning för personer med dyslexi. Slutsatserna betonade behovet av att minimera den kognitiva belastningen och att välja typsnitt med en enklare design för att främja läsbarhet. Slutligen identifierade även studien ökat bokstavsavstånd som en strategi för att förbättra läsbarheten på mobilskärmar för personer med dyslexi.

Approved for public release, distribution is unlimited / Modern technology is making virtual environments a part of daily life. However, some constraints about the usage of virtual environments, such as the need for high performance and well-configured computers, prevent users from accessing virtual environments in some places other than special computer rooms. Mobile devices may be used to solve this limitation in a virtual environment. The remote-control approach to access virtual worlds on the Internet or on a corporate network is a new concept that opens new doors to users. First step of this approach is already in use, such as games implemented for mobile devices using the screen of a mobile device as display, and has given satisfying results for some users. This research will take the user, who not only wants to be mobile but also does not want to sacrifice high resolution textures and complex models, closer to his/her goal. Mobile devices provide mobility to the user, but sacrifice not only the reality of the virtual environments but also screen size, which is very important for visibility of complex virtual environments. The hybrid approach with wireless internet connection by using mobile devices as remote control gives the user the advantages of mobility over desktop PCs. On the other hand, the realism provided by high-quality PCs on the server side exceeds the capabilities of mobile devices. / Lieutenant Junior Grade, Turkish Navy

Smartphones and other mobile devices are a common sight in our daily lives. The improvement in technology has given us small and portable devices that have the performance only found in desktop computers and more high-end devices less than a decade ago. An industry that has been quick to adopt technologies in the past is the manufacturing industry, examples of these adoptions are the conveyor belt and robots, which both are innovations of their time. Aside from hardware technologies, there are software technologies that the manufacturing industry has been using, e.g. complex information systems to manage materials and resources in the production. With the developments in mobile technology, a question arises whether the information systems can be combined with it in the manufacturing companies. One of the technologies that has become popular in the past years is the use of mobile devices such as smartphones and tablets. These kinds of devices can improve communication and flexibility. This leads us to the purpose of identifying how the use of ERP-connected mobile and mobility-supporting devices can affect processes among shop floor and production management personnel in large manufacturing companies. Using a qualitative approach, case studies of eleven companies were conducted using semi-structured interviews and direct observations. Personnel with different roles were interviewed to identify applications and devices that would reduce execution time, improve quality, or improve the flexibility of processes and tasks. These eleven companies were analysed with a model that focus on the dimensions complexity, specificity, and dynamism of a company's production structure, as well as a model that focus on the same dimensions in the roles of production personnel. The result was six applications and corresponding devices that could improve the effectiveness and efficiency of a process in a significant way. The analysis showed that the management in companies had similar needs in mobile or mobility-supporting devices. Similarly, the assemblers and machine operators also had similar needs. No connection was found between the production strategy and the need for mobile or mobility-supporting devices.

Protocolos de autenticação e de estabelecimento de chaves são peças fundamentais em implementações de segurança para comunicação de dispositivos eletrônicos. Em aplicações que envolvam dispositivos com poder computacional restrito (tais como smartphones ou tablets) comunicando-se com um servidor, é primordial a escolha de protocolos eficientes e que necessitem de uma infraestrutura mais simples. Neste trabalho selecionamos e implementamos protocolos de acordo de chave seguros nos modelos de criptografia de chave pública baseado em identidade (ID-based) e sem certificado (Certificateless) em plataformas com processadores ARM. Comparamos tempos de execução, utilização de memória e uso do canal de comunicação. / Protocols for authentication and key establishment are fundamental parts in security implementations for electronic devices communication. In applications involving devices with limited computational power (such as smartphones and tablets) communicating with a server, the choice of efficient protocols that require a simpler infrastructure is essential. In this work we select and implement secure key agreement protocols in ID-based and Certificateless public key cryptography models on ARM processor platforms. We also compare running times, memory and network usage.

O presente trabalho propõe uma análise e reflexão sobre a produção de música eletrônica experimental mediada por dispositivos móveis. O termo Música Móvel é usado frequentemente desde de meados dos anos 2000, devido ao grupo de pesquisadores de instituições inglesas ligados aos Mobile Music Workshops, que ocorreram entre 2004 e 2008. As pesquisas acadêmicas e artísticas apresentadas nesse evento envolviam obras e aplicações mediadas por diversos tipos de dispositivos, cujo foco principal seria explorar a mobilidade de interfaces eletrônicas em situações interativas no espaço urbano. Após o lançamento de dispositivos móveis corporativos, como smartphones e tablets, no final da década passada a perspectiva das pesquisas acadêmicas mudou bastante: passou a privilegiar os objetos de consumo, ao invés de situações. Esse câmbio de foco acarreta em alterações significativas entre consumo e produção de cultural. Pois essas interfaces seguem um modelo de consumo assimétrico entre possibilidades de produção e aquisição. Os dispositivos corporativos são primordialmente plataformas de Consumo Controlado, baseadas na lógica de monopólio de mercado, vigilância, obsolescência programada e, portanto, causam reorganizações significativas em nosso dia a dia (STRIPHAS,2011). Portanto, nesse texto especulamos sobre outras alternativas para as práticas de Música Móvel. Uma Música Móvel Crítica, que não depende exclusivamente dos monopólios empresariais para sua produção e veiculação. Para isso propomos uma reflexão sobre fidelidade sonora que acarreta em uma defesa dos sons e dispositivos precários - o proletariado da reprodução sonora - aqueles que compõem a paisagem sonora eletrônica de baixa fidelidade do cotidiano. / This research aims to propose an analysis and reflection on the production of experimental electronic music mediated by mobile devices. The term Mobile Music is frequently used since the mid-2000s, due to a group of researchers of English institutions connected to the Mobile Music Workshop, which took place between 2004 and 2008. The academic and artistic research presented at this event involved works and applications mediated by various types of devices, among the experiences the main focus was to explore the mobility of electronic interfaces in interactive situations in urban space. After the release of corporate mobile devices such as smartphones and tablets at the end of the last decade the perspective of academic research has changed a lot: it started chater objects of consumption rather than situations. This change of focus brings in significant changes between consumption and cultural production. Because these interfaces follow a asymmetric model of consumption between possibilities production and procurement. Corporate devices are primarily controlled consumption platforms, which are based on market monopoly, surveillance, planned obsolescence, and therefore cause significant reorganizations in our daily lives (STRIPHAS, 2011).Thus in this text we speculate about other alternatives to the practices of Mobile Music. A Critical Mobile Music, which does not depend solely on corporate monopolies for its production and propagation. Therefore we propose a reflection on issues of sound fidelity, in order to make that we propose a defense of precarious sounds and devices - the proletariat of sound reproduction - those that make the electronic low fidelity soundscape of everyday life.

Mobile devices have influenced the creation of unusual narratives that investigate, among other things, the relationship between space and individual. This essay intends to discuss the changes that this relationship has suffered due to the spread of pervasive computing, and how these changes enabled the emergence of new trends in aesthetic technology. Mobile devices of communication re-invent urban environments, such as multiplayer connected environments independent of the geographical position and physical presence, encouraging the emergence of hybrid spaces, which is defined by the disappearance of borders between physical and virtual and created by a constant mobility of users who use handsets. As theoretical support, the thinking is based on studies of André Lemos, Lúcia Santaella, Milton Santos, Pierre Lévy, and artists such as Jeremy Hight, the English Blast Theory. The essay intends to introduce a scenario of aesthetic technology based on mobile devices and the public spaces, and through an specific case show how is the relationship between narrative and technologies in hybrid spaces / Assim como os movimentos artísticos, o ato de narrar, de contar histórias, também se transformou consideravelmente com os avanços técnicos. Os dispositivos móveis têm influenciado criações narrativas inusitadas e que investigam, entre outras coisas, a relação entre espaço e indivíduo. A presente dissertação discute as transformações que essa relação tem sofrido devido à disseminação da computação pervasiva, e de que forma essas transformações propiciaram o surgimento de novas tendências da estética tecnológica. Os dispositivos móveis de comunicação re-inventam espaços urbanos como ambientes de multiusuários conectados independentemente da posição geográfica e presença física, favorecendo o surgimento de espaços híbridos, ou seja, definidos pelo desaparecimento das bordas entre físico e virtual e criados pela constante mobilidade dos usuários que utilizam aparelhos portáteis. Como referencial teórico, a reflexão se fundamenta nos estudos de André Lemos, Lúcia Santaella, Milton Santos, Pierre Lévy, e artistas como Jeremy Hight e o grupo inglês Blast Theory por ser uma pesquisa de caráter multidisciplinar. O recorte feito visa introduzir um cenário estético tecnológico com dispositivos móveis com foco em espaços públicos e através de um estudo de caso apresentar a relação entre criação narrativa em espaços híbridos

Technology integration continues to be a professional development concern, especially in elementary schools. It remains unclear why there is a difference between how teachers talk about using technology and how they apply it in teaching reading. The purpose of this study was to explore professional development options that would help teachers connect theory to practice by studying their decision-making process. The conceptual framework was based on elements of the knowing-doing gap and reflective practices. The research questions explored (a) the decision-making process, (b) reflective practices used during decision-making, (c) professional development that facilitates closing the knowing-doing gap, and (d) recommendations from participants to improve upon professional development. In a case study design, 10 K-4 teachers participated in one 60-minute interview, one follow-up interview, and one 45-minute focus group. With the use of typological analysis, transcripts were coded for initial and emerging themes. Results indicated that integrating mobile devices was highly dependent upon teachers being self-directed learners. Teachers relied on informal collegial interactions when deciding to use mobile devices. Continuous professional development that addresses adult learning styles was recommended by the teachers to support technology adoption. Improvements to reading instruction lead to positive social change by increasing student achievement, thereby preparing students to be world citizens in a competitive global market.
