[pt] Usabilidade em e-learning: avaliação de métodos de apresentação de conteúdo para ensino de software de computação gráfica. Através da internet o conceito de educação a distância foi ampliado de forma significativa. A facilidade de transmissão de conteúdo via internet vem sendo considerada uma alternativa muito útil para o desenvolvimento e capacitação de alunos ao longo dos últimos anos. Essa pesquisa tem como objeto de estudo a interação entre os alunos de design e os sistemas de ensino disponíveis na plataforma web (e-learning) no aprendizado de softwares de computação gráfica. O Brasil encontra-se em fase de consolidação da educação a distância, mas a falta de experiência na transposição do método de ensino para uma nova plataforma de distribuição de informação acarreta em propostas de ensino por vezes dispendiosa e equivocada. Faz-se necessário um conhecimento sólido sobre o comportamento do usuário antes de definir a interface da plataforma. Através de três protótipos de e-learning pôde-se verificar a eficiência e a completude de tarefas propostas a partir das variações no design da interface e nos componentes que apresentam o conteúdo da disciplina. Os resultados obtidos demonstraram que o design de interface para e-learning que leva em conta a redução da carga cognitiva do usuário, usando componentes de apresentação adequados, favorece a compreensão e aprendizado dos softwares de computação gráfica. A pesquisa também comprova que os componentes de vídeo, texto, ilustrações e disponibilidade de arquivos digitais relacionados à tarefa proposta pela disciplina também favorecem um aprendizado mais imersivo e eficiente. / [en] Usability in e-learning: evaluation of methods of presentation of content for teaching computer graphics software. Through the internet the concept of distance education has been significantly expanded. Its ease of transmission has been considered a very useful alternative for the development and training of students over the last few years. This research has as object of study the interaction between design students and education systems available on the web platform (elearning) in learning computer graphics software. Brazil is in the process of consolidating distance education, but the lack of experience in transposing the teaching method to a new information distribution platform leads to sometimes expensive and misleading teaching proposals. A solid understanding of user behavior is necessary before defining the platform interface. Through three prototypes of e-learning it was possible to verify the efficiency and completeness of tasks proposed from the variations in the design of the interface and in the components that present the content of the discipline. The results showed that the e-learning interface design, which takes into account the reduction of the user s cognitive load, using appropriate presentation components, favors the understanding and learning of computer graphics software. The research also proves that the video components, text, illustrations and availability of digital files related to the task proposed by the discipline also favor a more immersive and efficient learning.

A presente pesquisa pretende demonstrar como o design, por meio do conhecimento das características cognitivas e psicológicas de crianças de educação infantil (idade entre quatro e cinco anos, de acordo com o MEC), frente às possibilidades tecnológicas do ambiente da TV Digital Interativa (TVDi) pode gerar diretrizes projetuais que permitam o desenvolvimento de aplicativos e que venham a auxiliar a construção de experiências mais ativas a esses usuários. Supõe-se que através da criação e sincronização desses elementos, se pode proporcionar o desenvolvimento de interfaces gráficas amigáveis (IGA´s) mais eficientes na construção do conhecimento. A pesquisa advém da necessidade de projetar aplicativos que utilizem de forma mais eficaz as possibilidades interativas, bem como contribuir com iniciativas que permitam o uso da TVDi como ferramenta de inclusão tecnológica e social. Esse cenário de pesquisa apresenta-se propício ao se verificar a abrangência da TV nos lares brasileiros, bem como a conversão definitiva do sinal analógico para digital, que ocorrerá até o ano de 2018. A investigação teórica relata os impactos na relação entre a criança e televisão a partir de estudos conduzidos ao longo dos anos, e busca entender como a informação é percebida por usuários nessa faixa etária, bem como estabelecer a abordagem narrativa mais adequada a esse usuário. Essa fase gerou diretrizes que embasaram o instrumento de coleta de dados por meio da pesquisa de campo, conduzidas a partir de entrevistas com especialistas das áreas de psicopedagogia, narrativa e design. A interpretação dos dados através do confronto proveniente da pesquisa teórica e prática dessas áreas do conhecimento geraram diretrizes de projeto de interface que tiveram a comprovação de sua eficácia em sua aplicabilidade por meio da avaliação em atividade de grupo focal, formado por especialistas da área do design. Essa etapa final da pesquisa resultou em um conjunto de diretrizes capazes de auxiliar desenvolvedores e projetistas a potencializarem a experiência da criança em educação infantil através da interatividade nos ambientes digitais. Finaliza-se com conclusões e contribuições e sugestões para futuros estudos. / This research aims to demonstrate how the design, through the knowledge of cognitive and psychological characteristics of childhood education (ages four and five, according to the Brazil’s Ministry of Education), toward to the environment of the technological capabilities of the Interactive Digital TV (iDTV), can generate projective guidelines that enable the development of applications which will help to build more active experiences for those users. It is assumed that through the creation and synchronization of these, it can provide the development of friendly graphical user interfaces (IGA's) more efficient in the construction of knowledge. The research comes from the need to design applications that use more effectively the interactive possibilities and contribute to effort to enable the use of iDTV as technological and social inclusion tool. This scenario research presents conducive to verify the scope of TV in Brazilian homes, and the final conversion of the analog signal to digital, which will occur by the year 2018. The theoretical research reports the impacts on the relationship between the child and television from studies conducted over the years, and seeks to understand how information is perceived by users in this age group and also to establish the most appropriate narrative approach to this user. This phase generated guidelines which supported the data collection instrument through field research, conducted through interviews with experts in educational psychology, narrative and design areas. Interpretation of the data through the coming confrontation of theoretical and practical research of these areas of knowledge generated interface design guidelines that had the evidence of its effectiveness in its applicability through the evaluation focus group activity, comprising the area of design experts. This final stage of the study resulted in a set of guidelines that can assist developers and designers potentiating the child's experience in early childhood education through interactivity in digital environments. The research ends with conclusions, contributions and suggestions for future studies.

Människans tankesätt och beslutsfattande är en alldeles unik egenskap, som hon har. Unik är den på grund av att alla har olika uppfattningar, erfarenheter och värderingar. Den här studien handlar om hur man kan påverka människans beslutsfattande genom ett gränssnitt, och vad det är som påverkar beslutet. Då det finns många faktorer som har en påverkan på beslutsfattande, specialiserades studien på användaren och dess kognitiva egenskaper, så som uppmärksamhet och perception, samt en fördjupning på beslutsfattande och gränssnittsdesign. Detta för att kunna svara på vilken påverkan ett gränssnitt har på en människa som interagerar med det.Under studiens gång gjordes enkätundersökning, personas, prototyper, användartester, samt observationer, för att kunna analysera och få in tillräcklig data. I den här studien har en egen modell tagits fram som förklarar vilka faktorer som påverkar sättet hur en person fattar beslut, och hur gränssnittsdesign även kan ha en påverkan i beslutsfattandet. Modellen har tagits fram och fungerat mer som en riktlinje för framtagandet av just gränssnitt, och utifrån användartester och personas som gjordes kunde dessa bekräfta modellen, vilket i sin tur kunde ge ett konkret svar på syftet med studien. En viktig del av det som har noterats genom studiens gång är heta och svala medier, som har en stor påverkan på hur människan uppfattar och tolkar mediet, och som på så sätt påverkan beslutsfattandet. / A humans’ way of thinking and making decisions is an absolute unique feature of hers. It is unique because every single person has different understandings, experiences and values. This research is about understands how it is possible to affect a person’s way of making decisions, through manipulating an interface, and what factors includes in decision-making. As there are many factors that have an impact on decision-making, was this research specialized on the user and his cognitive characteristics, such as, attention and perception, as well as a recess on decision-making and interface design. This was done to get the result of how an interface affects a human that interacts with it.There were several methods used, during this research, such as a survey, personas, prototypes, user tests and observations, to get enough data to analyze. There are several elements that have an impact on a humans decision-making, and a model has been made that works as a guideline for interface design. The model describes what elements effect and how they affect a person, through an interface. After making user tests and personas, were these results compared to the model, which could give a proper answer to this research. An important factor that was noticed, was that hot and cold media plays an important role in an interface design, since hot and cold media can be interpreted differently by a person.

Electronic networks services have become essential tools for the academic community. One of the services provided has been academic electronic bulletin boards (EBBs), and the use of EBBs has increased dramatically during the last decade. One question concerns the possible application of EBBs as a means both for communication and for remote training. A series of experiments were conducted during 1991, 1992, and 1993 with the aim of examining the use of EBBs for these purposes. The first experiment was carried out to investigate whether users experience problems in using EBBs. The next extended this to see how students evaluated EBBs for communication and training purposes. The main focus of the work was BUBL. After this second experiment, modifications were made to the BUBL data and a further experiment was carried out. A different group of students looked at the modified material, and also compared it with US data using different software. The fourth experiment compared the usability of a menu-based interface (dBase III +) and a hypertext interface (HyperCard) from a student's viewpoint. It was followed by an investigation of icons to find out how well different icons could be recognised and the possibility of using them for language-independent instructions. Finally, the characteristics and problems of GULFNET users were examined. The evaluation has demonstrated the general acceptability of EBBs and their likely value for training purposes. This leads to a discussion of how an EBB might best be developed for use in communication and training on GULFNET.

Syfte – Att se hur olika processer vid framtagningen av ett gränssnitt kan påverka kvaliteten på ett gränssnitts användarvänlighet. Metod – Fallstudie med intervjuer och kontextuella observationer och en designprocess som använder flera iterationer av prototyper. Slutligen en analys där arbetsprocessen vid gränssnittens utveckling tolkas och gränssnittens kvalitet utvärderas utifrån ett antal definierade faktorer. Resultat – Studien visar att en designprocess med ett fokus på användarvänlighet kräver mycket förarbete och tar längre tid för att få fram ett resultat medan en designprocess där användarvänlighet ej är i fokus ger ett snabbare resultat men som ger problem i efterhand på grund av lägre kvalitet på gränssnittets användarvänlighet Implikationer – Studien visar att även om en process som fokuserar på användarvänlighet kräver extra arbete och resurser i början, i slutändan ger ett betydligt högre resultat som sparar framtida arbete. Studien bekräftar därmed andra teorier om hur användarvänlighet i gränssnitt kan och bör tas fram. Begränsningar – Studien saknade möjlighet till tester i gränssnittets slutliga miljö och baseras därför på teorier framtagna utifrån ISOs definition av Quality in use istället för användartester som skulle kunnat ge en trovärdigare kvalitetsuppskattning. Studien studerar endast två olika processer för framtagning av ett gränssnitt. / Purpose – To see how different processes during the development of a User Interface affect the quality of its user-friendliness. Method – Case study with interviews and contextual observations and a design process where several iterations of prototypes was used. Lastly an analys where the process used during the development is studied and the quality of the User Interface is valued from a number of defined factors. Findings – The study shows that a design process with a focus on user-friendliness requires a lot of work beforehand and takes longer before an actual result kan be achieved while a process where user-friendliness is not a focus gives faster results but creates problems in the future because of a lower quality on the user-friendliness of the User Interface. Implications – The study shows that a while process with a focus on user-friendliness takes more resources and time in the beginning it produces a higher quality of work which saves time and resources in the future. The study therefor other studies of how a user-friendly User Interface can and should be developed. Limitations – The study lacked an opportunity to do testing in the User Interface’s real environment and is instead based on theories based on ISO’s definition of Quality in use instead of user tests which could have given a more credible result. The study also only studies two different processes and their result.

The question of the relationship between, and the importance of usability and aesthetics, in the field of user interface design, has been debated back and forth. It has also been looked at from different perspectives since Raskin (1994) wrote his article on intuitive design. Several experiments have also been conducted over the last twenty years to find out exactly how much each factor matter, what the ultimate user preference is, and if it can be stereotyped. The more complex part of the discussion, however, seems to be the definitions: exactly what is aesthetics, what is usability and how do they affect each other? To find out, I explored the context of these factors from multiple perspectives, to draw the larger conclusions about what affects what. How accurate is the concept of halo when it comes to interface design; can a less aesthetic interface discourage users from exploring its content? Moreover, can a highly usable interface convince its users that the web page is also aesthetically pleasing? In this paper I will explain the ideas of aesthetic and intuitive design based on two fields of study; human computer interaction design and interaction design. That is in the pursuance of understanding user preference and the design decisions behind one of the most popular interfaces on the internet today.

Communication between people has become more and more important in society today and so has the way to communicate. Our work, which this master thesis is based upon, has been to evaluate and redesign an existing web application that works like a communication tool. To carry out this work we have compiled two questions; how to facilitate the interaction for an application that is used as a tool, focusing on interface design, usability and flow; how can the usability be improved in a system, with help of flow theory. To deal with these two questions we have used a number of methods that have had different kinds of influence of our work. The one that has had the greatest impact of the work with the evaluation has been cognitive walkthrough. For the design we have used literature studies along with the result of the evaluation. A problem during our work has been that the user has not been specified the design should work at a generic group of users. The problem has not been to define the target group rather to suit the interface to everybody. This has been the challenge of this semester and we found designing an interface infusing usability with help from flow as interesting. / Kommunikation mellan människor liksom sättet att kommunicera har blivit allt viktigare i samhället idag. Vårt arbete, som magisterarbetet bygger på, har varit att utvärdera och omdesigna en existerande webbapplikation som fungerar som ett kommunikationsverktyg. För att genomföra arbetet har vi utarbetat två frågor; hur förenklas interaktion för en applikation som används som ett verktyg, med fokus på gränssnittsdesign, användbarhet och flow; hur kan användbarheten öka i ett system, med hjälp av flow teorin. För att kunna ta itu med dessa frågor har vi använt ett antal metoder som har påverkat vårt arbete på olika sätt. Den för arbetet med utvärderingen mest betydelsefulla har varit kognitiv genomgång. För designen har vi använt oss av literaturstudier tillsammans med resultatet från utvärderingen. Ett problem under vårt arbete har varit att användarna inte har varit specificerade utan designen bör fungera på en allmän grupp användare. Problemet har inte varit att definiera målgruppen utan snarare att anpassa gränssnittet till alla. Detta har varit en av utmaningarna under denna termin och vi tycker en annan intressant utmaning har varit att designa ett gränssnitt genom att ingjuta användbarhet med hjälp från flow.

Augmented Reality, eller förstärkt verklighet som det heter på svenska, är en teknologi som funnits i någon form sedan mer än 30 år tillbaka. Förstärkt verklighet system bygger och lägger virtuella objekt på vår syn av verkligheten, antingen genom video eller en genomskinlig display. Trots sin långa historia har det bara nyligen kunnat börja utvecklas i någon betydande mening, därför att den är starkt begränsad av processor- och display-teknik. Förutom tekniska begränsningar möter den också begränsningar i form av användarens kapacitet att bearbeta information som ett system matar ut. Om mängden information överskrider kapaciteten blir användaren överbelastad, ett tillstånd som kallas för Information Overload, vilket resulterar i att användaren får svårt att ta in och begripa information. Detta kan åthjälpas genom att utöva god design av användargränssnittet, som är en viktig del i alla system. Militären är mycket intresserade i teknologin i hopp om att det ska ge dem en bättre överblick på slagfältet. Den miljö som råder på ett slagfält kan dock vara mycket stressande, vilket ökar risken för Information Overload och gör det till en större utmaning att designa ett användbart system. Denna uppsats syftar att samla information om förstärkt verklighet, Informaion Overload och gränssnittsdesign på ett ställe och applicera det på ett militärt projekt, för att undersöka vilka utmaningar som uppstår när man designar för militärt bruk, utifrån traditionella riktlinjer och principer.
