[en] MODELS AND FORMALISMS FOR THE SEMIOTIC ENGINEERING OF USER INTERFACES / [es] MODELOS Y FORMALISMOS PARA LA INGENIERÍA SEIÓTICA DE INTERFACES DE USUARIO / [pt] MODELOS E FORMALISMOS PARA A ENGENHARIA SEMIÓTICA DE INTERFACES DE USUÁRIO

JAIR CAVALCANTI LEITE 10 August 2001 (has links)
[pt] Um dos requisitos para a usabilidade de um sistema interativo é que os usuários adquiram o conhecimento, denominado de modelo de usabilidade, sobre como aplicar as soluções-em-potencial concebidas pelo designer às tarefas do seu domínio. A abordagem da Engenharia Semiótica apresenta uma perspectiva na qual um sistema interativo é um artefato de metacomunicação através do qual o designer envia uma mensagem que comunica o modelo de usabilidade para o usuário. Partindo desta perspectiva e baseado nos conceitos de semiótica das teorias de Charles S. Peirce e de Umberto Eco desenvolvemos modelos teóricos que descrevem o modelo de usabilidade como sendo o conteúdo da mensagem do designer, a interface de usuário como a sua expressão e o design como sendo uma atividade de produção de signos apoiada por um sistema semiótico, composto por uma linguagem de especificação e por regras que correlacionam as mensagens especificadas aos widgets dos principais padrões e ferramentas de interfaces de usuário. / [en] Interactive systems usability could be enhanced if users learn all the knowledge - the usabilty model - that capability them in applying designer`s potential solutions to domain tasks. The Semiotic Engineering approach perceives interactive systems as metacommunication artifacts that send a message from designer to users whose expression is the lower-level messages exchanged between user and system and whose content is the usability model. Starting from this perspective and based on semiotic theory concepts from Charles S. Peirce and Umberto Eco we present conceptual models to the interface as the expression and to the usability model as the content of designer`s message. We also develop a semiotic system to support user interface design. The system is composed by a specification language and rules that maps specified messagens to user interface widgets. Our emphasis here is not in aesthetics aspects of user interfaces, but in the interactive and performing nature of the interface message as it is carried throughout the computational medium. / [es] Uno de los requisitos para el uso de un sistema interactivo es que los usuarios adquieran conocimiento (denominado de modelo de usabilidad) sobre como aplicar las soluciones-en-potencial concebidas por el diseñador a las tareas de su dominio.

"Windows of culture : an analysis of Israeli ORT school websites"

Giladi, Michal 17 March 2005 (has links)
School websites are useful in providing an additional environment to educate and impart culture to the collectivity. They reflect the collective phenomenon of behaviour and traditional ideas, and at the same time, reflect the efforts made by the educators to teach cultural identity, values and social skills. The work of renowned anthropologist Geert Hofstede (1991) on cultural dimensions has contributed to the study and reassessment of current theories on software and websites, which interact with the cultures of societies in which they function, and are still relevant to the constant evolution of technology (communication tools) in the educational environment. The aim of this research is to explore how cultural dimensions are reflected on ORT school websites in Israel. This study in a relatively new field offers educators an insight into new options and innovations offered by school websites, and provides reflections on their use in cultural education. In this context, the importance of this research lies in its contribution to the pedagogical dialogue on culture, and as it is reflected on school websites. This study applies Hofstede's (1991) work, in which he classifies cultural characteristics prevalent in global organizations into five "cultural dimensions": power distance, individualism&collectivism, masculinity&femininity, uncertainty avoidance, and time orientation, and design expert Aaron Marcus' (2001) interpretation and application of this model to website designs worldwide. The subject of this study consists of 54 Ort school websites operating in Israel. The findings on ORT school websites echo Hofstede's characteristics on the reflection of power distance in Israeli culture. However, my findings on Hofstede's three other dimensions – collectivism vs. individualism, masculinity vs. femininity, and uncertainty avoidance – illustrate a more complex picture, with the elements reflected in differing patterns. ORT school websites reflect both elements of culture as defined by Marcus (2001) and elements of standardization of website design. In recent years, there has been an upsurge in the software available globally to create and design websites, all using the same basic tools and elements of design. In conclusion, schools' attempts to impart culture as part of their social education policies is reflected in the contents and design of their websites. / Dissertation (MEd (Curriculum Studies))--University of Pretoria, 2006. / Curriculum Studies / unrestricted

Augmented Reality als intuitive Benutzungsschnittstelle für das Roboterprogrammieren

Horn, Carolin, Schreiber, Christoph-Philipp 06 September 2021 (has links)
Das Programmieren der Bewegungsbahnen von Robotern erfordert Fachwissen und ist ein zeitintensiver und aufwendiger Prozess. Dieser Beitrag beschäftigt sich mit dem Einsatz von Augmented Reality (AR) in Form eines AR Head Mounted Display (HMD) als intuitives Schnittstelle (engl. Interface) für die Roboterprogrammierung. Zunächst wird ein Überblick über aktuelle und relevante Forschung im Bereich AR Anwendungen in der Robotik gegeben. Aktuelle Forschungsarbeit auf dem Gebiet widmet sich vorrangig der technischen Umsetzung einzelner Funktionalitäten. In diesem Beitrag aus der Praxis sollen die technischen Möglichkeiten den Problematiken potenzieller Anwender:innen angepasst werden. Der Fokus liegt damit auf dem Mehrwert für spezifische Nutzergruppen und der einfachen und intuitiven Bedienung des AR Interfaces selbst. Zunächst wird, einem nutzerzentrierten Entwicklungsprozess folgend, erhoben, welchen Herausforderungen Expert:innen und Laien bei der Roboterprogrammierung begegnen. Auf dieser Basis werden Anforderungen abgeleitet und ein erlebbarer Prototyp entwickelt und gestaltet, der eine weitere Untersuchungen ermöglicht. Ein geplantes Untersuchungskonzept hinsichtlich Aspekten der User Experience (UX) wird im Ausblick beleuchtet.

Building a design system for a startup : A case study exploring how an open-source component library can assist a start-up in the creation of a design system

Häger, Erik January 2021 (has links)
The purpose of this thesis is to develop a deeper understanding of the potential benefits of using an open-source library when building a design system. The thesis uses a research through design approach in three steps; (1) identifying what a design system contains and the possible advantages of using one. (2) Building a design system based on an open-source library. (3) Evaluate how the new design system performs by comparing its performance to the possible advantages identified in step (1). In the result chapter, the design system is presented, and the design is motivated based on the brand identity. The discussion evaluates what pros and cons it might bring to use an open-source design system compared to the general advantages of design systems mentioned in the literature. It also evaluates the process and provides knowledge for anyone wanting to use an open-source design system. In the conclusion, this thesis argues that itis useful and time-saving for any company to use an open-source library when it comes to simpleand often recurring components. However, since every application solves specific problems, the creation of unique components is inevitable. Using already designed components could also limit the ideation process since the designer already have a toolkit to use when solving problems.

Optimización del diseño de interfaz del aplicativo móvil “Viajo Seguro-SMP” de la municipalidad de San Martin de Porres / Optimization of the interface designn of the mobile application “Viajo Seguro-SMP” of the municipality of San Martin de Porres

Esquives Sáenz, Katherinne Lizbeth 09 July 2021 (has links)
La Municipalidad de San Martin de Porres junto con la subgerencia de transporte del distrito desarrollaron el aplicativo móvil Viajo Seguro SMP en abril del 2019. El problema de comunicación que se encontró fue una interfaz que no aportaba a la experiencia del usuario de mototaxis y tampoco solucionaba el problema de informalidad en el distrito. Teniendo en cuenta que en la actualidad circulan más de 8000 mil vehículos menores, de los cuales solo 2800 son formales. Este problema se vuelve relevante para el diseño gráfico porque encontramos fallas en el diseño de interfaz y también la necesidad de un sistema gráfico donde el usuario pueda identificar de manera visual una mototaxi formal. La propuesta de solución es una mejora al aplicativo, dándole la función principal de pedir una mototaxi, y creando todo un sistema gráfico que apoye a la identificación de vehículos formales. Los resultados arrojaron una mejor experiencia en el usuario, haciendo que sea una opción más rápida y segura. / The Municipality of San Martin de Porres together with the district's transportation submanagement developed the Viajo Seguro SMP mobile application in April 2019. The communication problem found was an interface design that did not contribute to the motorcycle taxi user experience and nor did it solve the problem of informality in the district. Taking into account that currently more than 8,000 thousand smaller vehicles circulate, of which only 2,800 are formal. This problem becomes relevant for graphic design because we find flaws in the UI design and also the need for a graphic system where the user can visually identify a formal motorcycle taxi. The solution proposal is an improvement to the application, giving it the main function of ordering a motorcycle taxi, and creating a whole graphic system that supports the identification of formal vehicles. The results yielded a better user experience, making it a faster and safer option. / Trabajo de Suficiencia Profesional

Evaluation of innovative computer-assisted transcription and translation strategies for video lecture repositories

Valor Miró, Juan Daniel 06 November 2017 (has links)
Nowadays, the technology enhanced learning area has experienced a strong growth with many new learning approaches like blended learning, flip teaching, massive open online courses, and open educational resources to complement face-to-face lectures. Specifically, video lectures are fast becoming an everyday educational resource in higher education for all of these new learning approaches, and they are being incorporated into existing university curricula around the world. Transcriptions and translations can improve the utility of these audiovisual assets, but rarely are present due to a lack of cost-effective solutions to do so. Lecture searchability, accessibility to people with impairments, translatability for foreign students, plagiarism detection, content recommendation, note-taking, and discovery of content-related videos are examples of advantages of the presence of transcriptions. For this reason, the aim of this thesis is to test in real-life case studies ways to obtain multilingual captions for video lectures in a cost-effective way by using state-of-the-art automatic speech recognition and machine translation techniques. Also, we explore interaction protocols to review these automatic transcriptions and translations, because unfortunately automatic subtitles are not error-free. In addition, we take a step further into multilingualism by extending our findings and evaluation to several languages. Finally, the outcomes of this thesis have been applied to thousands of video lectures in European universities and institutions. / Hoy en día, el área del aprendizaje mejorado por la tecnología ha experimentado un fuerte crecimiento con muchos nuevos enfoques de aprendizaje como el aprendizaje combinado, la clase inversa, los cursos masivos abiertos en línea, y nuevos recursos educativos abiertos para complementar las clases presenciales. En concreto, los videos docentes se están convirtiendo rápidamente en un recurso educativo cotidiano en la educación superior para todos estos nuevos enfoques de aprendizaje, y se están incorporando a los planes de estudios universitarios existentes en todo el mundo. Las transcripciones y las traducciones pueden mejorar la utilidad de estos recursos audiovisuales, pero rara vez están presentes debido a la falta de soluciones rentables para hacerlo. La búsqueda de y en los videos, la accesibilidad a personas con impedimentos, la traducción para estudiantes extranjeros, la detección de plagios, la recomendación de contenido, la toma de notas y el descubrimiento de videos relacionados son ejemplos de las ventajas de la presencia de transcripciones. Por esta razón, el objetivo de esta tesis es probar en casos de estudio de la vida real las formas de obtener subtítulos multilingües para videos docentes de una manera rentable, mediante el uso de técnicas avanzadas de reconocimiento automático de voz y de traducción automática. Además, exploramos diferentes modelos de interacción para revisar estas transcripciones y traducciones automáticas, pues desafortunadamente los subtítulos automáticos no están libres de errores. Además, damos un paso más en el multilingüismo extendiendo nuestros hallazgos y evaluaciones a muchos idiomas. Por último, destacar que los resultados de esta tesis se han aplicado a miles de vídeos docentes en universidades e instituciones europeas. / Hui en dia, l'àrea d'aprenentatge millorat per la tecnologia ha experimentat un fort creixement, amb molts nous enfocaments d'aprenentatge com l'aprenentatge combinat, la classe inversa, els cursos massius oberts en línia i nous recursos educatius oberts per tal de complementar les classes presencials. En concret, els vídeos docents s'estan convertint ràpidament en un recurs educatiu quotidià en l'educació superior per a tots aquests nous enfocaments d'aprenentatge i estan incorporant-se als plans d'estudi universitari existents arreu del món. Les transcripcions i les traduccions poden millorar la utilitat d'aquests recursos audiovisuals, però rara vegada estan presents a causa de la falta de solucions rendibles per fer-ho. La cerca de i als vídeos, l'accessibilitat a persones amb impediments, la traducció per estudiants estrangers, la detecció de plagi, la recomanació de contingut, la presa de notes i el descobriment de vídeos relacionats són un exemple dels avantatges de la presència de transcripcions. Per aquesta raó, l'objectiu d'aquesta tesi és provar en casos d'estudi de la vida real les formes d'obtenir subtítols multilingües per a vídeos docents d'una manera rendible, mitjançant l'ús de tècniques avançades de reconeixement automàtic de veu i de traducció automàtica. A més a més, s'exploren diferents models d'interacció per a revisar aquestes transcripcions i traduccions automàtiques, puix malauradament els subtítols automàtics no estan lliures d'errades. A més, es fa un pas més en el multilingüisme estenent els nostres descobriments i avaluacions a molts idiomes. Per últim, destacar que els resultats d'aquesta tesi s'han aplicat a milers de vídeos docents en universitats i institucions europees. / Valor Miró, JD. (2017).

Designing an Interactive tool for Cluster Analysis of Clickstream Data

Collin, Sara, Möllerberg, Ingrid January 2020 (has links)
The purpose of this study was to develop an interactive tool that enables identification of different types of users of an application based on clickstream data. A complex hierarchical clustering algorithm tool called Recursive Hierarchical Clustering (RHC) was used. RHC provides a visualisation of user types as clusters, where each cluster has its own distinguishing action pattern, i.e., one or several consecutive actions made by the user in the application. A case study was conducted on the mobile application Plick, which is an application for selling and buying second hand clothes. During the course of the project, the analysis and its result was discovered to be difficult to understand by the operators of the tool. The interactive tool had to be extended to visualise the complex analysis and its result in an intuitive way. A literature study of how humans interpret information, and how to present it to operators, was conducted and led to a redesign of the tool. More information was added to each cluster to enable further understanding of the clustering results. A clustering reconfiguration option was also created where operators of the tool got the possibility to interact with the analysis. In the reconfiguration, the operator could change the input file of the cluster analysis and thus the end result. Usability tests showed that the extra added information about the clusters served as an amplification and a verification of the original results presented by RHC. In some cases the original result presented by RHC was used as a verification to user group identification made by the operator solely based on the extra added information. The usability tests showed that the complex analysis with its results could be understood and configured without considerable comprehension of the algorithm. Instead it seemed like it could be successfully used in order to identify user types with help of visual clues in the interface and default settings in the reconfiguration. The visualisation tool is shown to be successful in identifying and visualising user groups in an intuitive way.

UX Design of Augmented Reality House Configurator : Mobile AR Application and Web Administration Interface Design

Skarin, Rebecka January 2020 (has links)
Many of us find it difficult to make big decisions, building ahouse is one of them. It is perhaps the biggest investment andproject that one takes on. During a house building project, thereare many things that needs to come together, you have to finda plot, choose a house model and lastly all those other choicesas for example the kitchen and bathroom details. It is in thisdecision process that it can be useful to be able to test differenthouse models and materials before the final decision is made.It is this process that is the focus of the thesis, or rather, a tool tofacilitate decisions. There are existing solutions today where the usercan change materials in houses online in virtual reality, this thesisexplores how this functionality could be conceived in an AR (AugmentedReality) environment. With this, the user can see their housein real size on the site before the construction has even begun.Neava AB has developed an application called Arvue where it is possibleto view an AR model of a house in real size. The houses NeavaAB produce belong to their customers, who are house companies.But as the team at Neava AB worked on developing customized configuratorsfor virtual reality, some challenges began to emerge.It takes a long time to agree with the customer which colour shadeis correct and the communication between the two at this stage ofproduction can sometimes take a long time. During which Neavahas to wait for the customer’s reply before they can continue theirwork. The problem regarding to the colours is also connected to thecustomers brand identity as the house companies all have their ownspecific appearance and want both the interface and images to reflectthis as strongly as possible. This increases the communicationbetween the two even further.The aim of the thesis is to design a tool where the house companycan administrate their own interface in the interactive AR configurator.The interface design is focused on user experience and evaluatedby measuring the usability and user experience.The work presented in this thesis applied a user centered designprocess, in which the most important part is to involve the users inthe design and to base the decisions upon their needs and feedbackin different ways. This work applied interviews, surveys, evaluationsand user testing continuously to control how well the results were inline with the identified needs.The thesis presents a proof of concept for how this tool for the housecompanies could be conceived by designing both the interface to administrateand the tool itself. By developing this tool Neava AB wouldboth reduce the time they spend on communication but also have aprogressive and innovative product service which could help reducethe environmental impact of building new houses. This is achievedby helping the users make better decisions and reduce the amountof re-buildt houses. / För många människor är det svårt att ta stora beslut, att bygga hus är ett av dessa. Det är kanske den största investeringen och projekt som man tar sig an. I ett husbygge är det många saker som ska stämma överrens, man ska hitta en tomt, välja en husmodell och till sist alla de där andra valen som till exempel köks- och badrumsdetaljer. Det är i detta beslutskede som det kan vara skönt att kunna testa olika husmodeller och material innan det slutliga beslutet tas. Det är denna process som är i fokus i detta examensarbete, eller rättare sagt ett verktyg för att underlätta besluten. Det handlar nämligenom en AR-applikation för hus. AR står för augmented reality(förstärkt verklighet) och med hjälp av denna kan användaren se sitt hus i verklig storlek på tomten innan någonting är bestämt eller ens påbörjat. Neava AB har utvecklat en applikation där det i dagsläget går att visa en AR-modell av ett hus i verklig storlek. Deras huvudsakliga kunder är husföretag som bygger modulära hus. Då teamet på Neava AB arbetat med att utveckla kundanpassade konfiguratorer för virtuell verklighet har några utmaningar börjat visa sig.Det tar lång tid att komma överens om vilken färgnyans som är korrekt och kommunikationen i detta skede av produktionen tar iblandväldigt lång tid varvid Neava måste invänta kundens bedöming påderas modeller. Detta problem är också kopplat till kundernas grafiska profil då kunderna alla har en specifik framtoning och vill att både gränssnitt och bilder ska återspegla denna så starkt som möjligt. Målsättningen med arbetet är att utforska hur ett verktyg för husföretagen att skapa sina egna gränssnitt skulle kunna se ut. Gränssnittet designas med fokus på användbarhet och användarupplevelse och utvärderas kontinuerligt jäntemot dessa kriterier. Projektet tillämpar en användarcentrerad designprocess där det centrala är att involvera användarna i designprocessen på olika sätt. Detta arbete tillämpar intervjuer, enkäter, utvärderingar och användartester genomgående för att kontrollera hur väl resultaten stämmer överrens med de identifierade behoven. Designen tas fram med utgånspunkt i de identifierade utmaningar och problem som funnits med hjälp av dessa metoder.Resultatet är ett koncept som illusterar hur detta verktyg skulle kunna se ut och fungera. Både hur en konfigurator för AR men också för hur en administrativ tjänst för en huskonfigurator skulle kunna se ut.Genom att designa gränssnittet för huskonfiguratorn i AR och medföljande administrativa tjänst så kunde ett förslag för detta verktyg presenteras. Om Neava skulle utveckla detta verktyg så skulle det både minska tiden som de lägger på kommunikation, men också ha tagit fram en innovativ och nytänkande produkt som kan bidra till att minska miljöpåverkan av nybyggnation genom säkrare beslut och minskad ombyggnation.
