Eignung von virtueller Physik und Touch-Gesten in Touchscreen-Benutzerschnittstellen für kritische Aufgaben

The goal of this reasearch was to examine if modern touch screen interaction concepts that are established on consumer electronic devices like smartphones can be used in time-critical and safety-critical use cases like for machine control or healthcare appliances. Several prevalent interaction concepts with and without touch gestures and virtual physics were tested experimentally in common use cases to assess their efficiency, error rate and user satisfaction during task completion. Based on the results, design recommendations for list scrolling and horizontal dialog navigation are given.Das Ziel dieser Forschungsarbeit war es zu untersuchen, ob moderne Touchscreen-Interaktionskonzepte, die auf Consumer-Electronic-Geräten wie Smartphones etabliert sind, für zeit- und sicherheitskritische Anwendungsfälle wie Maschinensteuerung und Medizingeräte geeignet sind. Mehrere gebräuchliche Interaktionskonzepte mit und ohne Touch-Gesten und virtueller Physik wurden in häufigen Anwendungsfällen experimentell auf ihre Effizienz, Fehlerrate und Nutzerzufriedenheit bei der Aufgabenlösung untersucht. Basierend auf den Resultaten werden Empfehlungen für das Scrollen in Listen und dem horizontalen Navigieren in mehrseitigen Software-Dialogen ausgesprochen

Modelo de referência para desenvolvimento de artefatos de apoio ao acesso dos surdos ao audiovisual

Tese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Ptograma de Pós-graduação em Engenharia e Gestão do ConhecimentoAs tecnologias da informação e comunicação possibilitam a participação do sujeito na sociedade do conhecimento, entretanto o tema da acessibilidade dos surdos aos conteúdos audiovisuais em meios digitais ainda demanda estudos para viabilizar sua efetiva e ampla adoção. Objetiva-se identificar e analisar as alternativas para o desenvolvimento de um modelo de referência que oriente o reuso de processos, métodos e técnicas para a produção de artefatos que promovam a acessibilidade de surdos aos conteúdos audiovisuais em plataformas digitais. A partir de uma revisão sistemática da literatura são apontados recomendações para apresentação de conteúdo audiovisual acessível ao público surdo, os requisitos que devem ser atendidos para promover as estratégias de acesso utilizadas por diferentes perfis de surdos, e enumeradas alternativas que podem apoiar estas demandas, como o uso de legendas textuais e com janela de língua de sinais. O modelo de referência contempla a produção de conteúdos a partir da tradução do material audiovisual, sendo identificadas e elaboradas recomendações para a geração de legendas em vídeo de língua de sinais ou na forma escrita. Busca-se integrar a produção destes tipos de artefatos, por meio de processos manuais ou automáticos sendo identificadas as mídias que apoiam ou são resultantes dos processos de produção de artefatos de apoio a acessibilidade. O modelo de referência é validado diante a consulta a especialistas e aplicado em uma implementação de referência de um sistema para acessibilidade com cenários de entrega na televisão digital interativa e na web. Como resultados são apresentadas as recomendações e alternativas em relação aos processos e mídias necessárias para a acessibilidade dos surdos ao audiovisual digital

Model-Driven Development of Interactive Multimedia Applications

The development of highly interactive multimedia applications is still a challenging and complex task. In addition to the application logic, multimedia applications typically provide a sophisticated user interface with integrated media objects. As a consequence, the development process involves different experts for software design, user interface design, and media design. There is still a lack of concepts for a systematic development which integrates these aspects. This thesis provides a model-driven development approach addressing this problem. Therefore it introduces the Multimedia Modeling Language (MML), a visual modeling language supporting a design phase in multimedia application development. The language is oriented on well-established software engineering concepts, like UML 2, and integrates concepts from the areas of multimedia development and model-based user interface development. MML allows the generation of code skeletons from the models. Thereby, the core idea is to generate code skeletons which can be directly processed in multimedia authoring tools. In this way, the strengths of both are combined: Authoring tools are used to perform the creative development tasks while models are used to design the overall application structure and to enable a well-coordinated development process. This is demonstrated using the professional authoring tool Adobe Flash. MML is supported by modeling and code generation tools which have been used to validate the approach over several years in various student projects and teaching courses. Additional prototypes have been developed to demonstrate, e.g., the ability to generate code for different target platforms. Finally, it is discussed how models can contribute in general to a better integration of well-structured software development and creative visual design
