電子連線與隨身行動裝置的興起，滿足了使用者希望能隨時隨地取得資訊的需求，而旅行者的資訊使用行為，恰巧符合此特性。一份資訊與介面設計良好的行動旅遊內容，不但可讓旅人減輕負擔，還可藉由行動連網獲取旅程中最即時的資訊。但目前應用於行動裝置平台上的旅遊資訊多偏向提供部分適地性服務（Location Based Service），亦即透過GPS等定位技術，確認使用者所在位置，進而提供相關資訊的服務，如主動提供當地加油、餐飲等各項資訊服務，此類適地性服務多為片段提供購物消費資訊，並非完整之旅遊資訊。本研究探討數位旅遊資訊內容該如何設計與呈現於具備影音、音樂、圖像、照相、電腦等多功能的行動裝置平台，以滿足使用者的資訊需求。研究首先提出一套行動旅遊資訊系統應包含的資訊內容與架構，然後進行雛型設計，最後評估測試此系統的適用程度。研究結果發現動態旅行的旅遊資訊，可在行動裝置平台尋得一個呈現的嶄新舞台。 / The integration of the internet and mobile devices satisfies the drsire of “information on the go”. This demand also matches the information usage behavior for travelers. A well designed mobile traveling information with convenient user interfaces helps them to get what they need at any moment while traveling through mobile internet. However, the current traveling information in mobile platform is usually location based services. The kind of services does not provide a complete traveling content but only small pieces of information. The thesis focuses on the design of an integrated digital content on mobile devices for the travelers. It includes the design of content structure, information display and user interface. The mobile platform targets on those who equipped with multimedia and 3G wireless communication ability. We propose a content planning and informative structure for traveling information. A prototyping system was first made to evaluate the concept of information design. Then the implementation and further evaluation was done by using the NOKIA N73 3G cell phone. The results show that personal mobile devices offering a new stage for the dynamic traveling information.

Under de senaste åren har den mobila tekniken i stort sett helt gått över till smartphones. Smartphones är i princip mer datorer än telefoner, som vi alltid bär med oss och som innehåller allt mer känslig information. Detta medför att kraven på säkerheten kring enheten ökar. Detta arbete undersöker om det är möjligt att finna en ny metod att låta användaren autentisera sig på, som är säkrare än de som är vedertagna idag, men samtidigt har liknande nivå av användbarhet. Vår idé, som vi arbetar med under namnet Colour a Symbol, baseras på att kombinera symboler och färger i par. För att utveckla idén skapade vi en funktionell prototyp, som sedan utvärderadesmed hjälp av en mindre testgrupp. Empirin visar på att Colour a Symbol har en god användbarhet, om än något för lång inloggningstid. Idéer för att förbättra inloggningstiden presenteras. Teoretiskt sett så är Colour a Symbol säkrare än exempelvis pinkod, men testgruppen var inte tillräckligt stor för att kunna bedöma den praktiska lösenordsrymden. Utformning av symboltema påverkar även förmodligen i hög grad den praktiska lösenordsrymden. Vår slutsats är att idén har en klar potential, men att det behövs ytterligare studier för att finslipa den. / During the past years mobile technology has moved almost entirely to smartphones. Smartphones are in essence more computers than phones, which we always carry with us and that contain ever more sensitive information. This requires that the level of security around the device increases. This study strives to find a new method of authenticating users, that is more secure than those that are established today, but at the same time has a similar level of usability. Our idea, which we work with under the name Colour a Symbol, is based upon making combinations of symbols and colours in pairs. In order to develop the idea we created a functional prototype, that was evaluated by a smaller test group. The empirical data implies that Colour a Symbol has good usability, if only a little too long login time. Ideas as to shorten the login time are suggested. Theoretically, Colour a Symbol is more secure than for an example pincode, but the test group was not large enough to estimate the practical password space. Design of the symbol theme probably also affects the practical password space to a high degree. Our conclusion is that the idea has clear potential, but that further studies are needed to fine-tune it.

<p>The Ericsson R380 is a so-called smartphone, combining an advanced mobile phone with a Personal Digital Assistant (PDA). To evaluate the usability of the Ericsson R380 and benchmark it against the Nokia 9110 Communicator and the Motorola A6188 Accompli, a repeated measurements experiment was performed. 18 subjects (10 men and 8 women) with no previous experience of any of the interfaces participated. Half of the subjects had extensive experience from using Ericsson mobile phones and half of the subjects had extensive experience from using Nokia mobile phones. A set of 9 tasks to be solved on each interface was presented to the subjects. The order in which the subjects used the interfaces was balanced with a Latin square design while the tasks were presented in consecutive order and were identical for all interfaces. Level of completeness, completion time and number of actions were assessed for each task and interface. Subjects also rated the perceived usability and aesthetics of the interfaces. Overall, subjects were most successful using the Motorola A6188 Accompli, using fewer keystrokes and less time as well as needing fewer hints compared to the Ericsson R380 and Nokia 9110 Communicator. However, the Ericsson R380 was rated significantly higher than the other interfaces on perceived usability. Previous experience with Ericsson or Nokia mobile phones did not have a major impact on how well subjects succeeded with using the interfaces in the test. Certain mistakes made by each group of subjects could be explained in terms of mental models, Einstellung effects and the use of so- called Function-Object interaction style where Object-Function interaction was appropriate. Contrary to earlier findings, aesthetics and perceived usability did not correspond to a great extent. Finally, the results are discussed and some suggestions for improvements are put forward.</p>

A pesquisa objetiva analisar as políticas de informação digital adotadas nas escolas públicas de ensino médio das capitais, localizadas na região Nordeste, no tocante a adoção dos dispositivos móveis para acesso a informação.Com objetivos específicos, foram mapeadas as escolas para fazer parte da amostra pesquisada. Em seguida a identificação dos dispositivos móveis utilizados nas escolas estudadas e a investigação das consequências da utilização dos dispositivos móveis para acesso à informação e por fim entender as razões da adoção ou não dos dispositivos móveis pelas escolas para fazer parte da investigação.Trata-se de uma pesquisa descritiva, com uma abordagem que se caracteriza enquanto qualitativa e quantitativa. Os procedimentos adotados se referem ao estudo de casos múltiplos e as técnicas basearam-se em questionários com professores das nove unidades federativas da região Nordeste. Para a execução da pesquisa, os professores do nível médio de nove unidades de ensino do Nordeste, sendo uma escola em cada capital, foram consultados por meio de questionários enviados por correio eletrônico. Nos questionários procurou-se investigar o conceito que o professor tem sobre o uso das tecnologias digitais móveis em sala de aula, quais dispositivos são adotados, se existe dificuldade no uso dessas tecnologias em sala, qual a frequência do uso nas aulas, qual a tecnologia digital mais adotada entre o celular, tablet e notebook e como é a experiência com o uso da tecnologia digital em sala de aula. Os resultados obtidos demonstram que o tablet um dispositivo móvel oferecido pelo Ministério da Educação a muitas escolas públicas da região Nordeste, principalmente para uso dos docentes, é uma das tecnologias móveis menos utilizada pelos professores. O celular e o notebook são ferramentas de trabalho mais utilizadas pelos professores nas aulas, não encontrando nenhuma dificuldade no uso e os resultados obtidos com essas tecnologias móveis em sala de aula, agregam valor na aquisição do conhecimento com relação as aulas sem o auxílio dessas tecnologias. Identificou-se exemplos de políticas de informação digital dentro das escolas em Fortaleza (CE) e em João Pessoa (PB) que podem servir como base na criação de uma política de informação digital em outros estados. Entre novembro de 2016 a abril de 2017 atenderam a pesquisa 08 (Oito) escolas das 09 (Nove) pesquisadas. / ABSTRACT There are vast experiences in digital technology education in the classroom in different Brazilian regions. The objective of this research is to analyze the digital information policies adopted in the public high schools of the capitals located in the Northeast region, regarding the adoption of mobile devices for access to information. For specific objectives, schools were mapped to be part of the sample surveyed. Next, the identification of the mobile devices used in the schools studied and the investigation of the consequences of the use of the mobile devices for access to the information and finally to understand the reasons of the adoption or not of the mobile devices by the schools to be part of the investigation. It is a descriptive research, with an approach that is characterized as qualitative and quantitative. The procedures adopted refer to the study of multiple cases and the techniques were based on questionnaires with teachers from the nine federative units of the Northeast region. For the execution of the research, the teachers of the average level of nine units of education of the Northeast - being a school in each capital - were consulted through questionnaires sent by electronic mail. The questionnaires sought to investigate the concept that the teacher has about the use of mobile digital technologies in the classroom, what devices are adopted, if there is difficulty in the use of these technologies in the classroom, how often the use in class, technology Digital technology most used between the cell phone, tablet and notebook and how is the experience with the use of digital technology in the classroom. The results show that the tablet, a mobile device offered by the Ministry of Education to many public schools in the Northeast region, mainly for the use of teachers, is one of the least used mobile technologies used by teachers. The mobile and the notebook are work tools most used by teachers in class, finding no difficulty in using and the results obtained with these mobile technologies in the classroom, add value in the acquisition of knowledge regarding the classes without the aid of these technologies . We have identified examples of digital information policies within schools in Fortaleza (CE) and João Pessoa (PB) that can serve as a basis for the creation of a digital information policy in other states. Between November of 2016 to April of 2017 attended the survey 08 (Eight) schools of the 09 (Nine) researched.

CAPES / Neste trabalho é realizada a análise da eficiência energética para algumas redes sem fio de curto alcance, como as redes de sensores sem fio, e algumas redes sem fio de longo alcance, como as redes de telefonia celular. Na análise de sensores sem fio são empregados esquemas de transmissão cooperativos e não-cooperativos, considerando que um canal de retorno pode estar disponível ou não. Para a análise de redes celulares, considera-se o uso de técnicas de transmissão com múltiplas antenas, modelos realistas de consumo de potência, além de um modelo de custos para a análise financeira de diferentes projetos de redes. São consideradas nas análises do desempenho de eficiência energética restrições como uma probabilidade de outage e uma vazão fim-a-fim alvos ao sistema. Os resultados obtidos indicam os esquemas de transmissão e projetos de redes mais eficientes para diferentes condições. Além disso, o planejamento dos direcionamentos para os trabalhos futuros é apresentado. / The energy efficiency analysis for some short-range wireless networks, such as wireless sensor networks, and for some long-range wireless networks, such as cellular networks is performed in this work. For the wireless sensor networks analysis, non-cooperative and cooperative transmission schemes (considering that a return channel is available or not) are employed. Multiple antennas transmission schemes, realistic power consumption models, and a cost model for different system designs are considered for the cellular networks analysis. We consider that the system is under constraints such as a target end-to-end outage probability and a target end-to-throughput. The results show the most efficient transmission schemes and network designs under different system conditions. The future works plans are also detailed.
