Describing Just-UI Concepts Using a Task Notation

ADUS: indirect generation of user interfaces on wireless devices

“…Basically the approaches are grouped into two main categories: web applications and classic desktop applications. While the first category [11,7] treats only web content and transformations of web content in order to be usable on other (mostly mobile) devices, the second category treats the problems of universal definition of the user interfaces, so it can be later reproduced by various program implementations [15,16,20] (or middleware) on various platforms.…”

Adaptive Interfaces in Mobile Environments

“…The user interface is typically abstracted through the use of design models (e.g., task models) or by using an XML-based abstract user definition language (Molina, Belenguer & Pastor, 2003;Luyten & Coninx, 2001;Mitrovic & Mena, 2002;Stottner, 2001). Task models (Limbourg & Vanderdonckt, 2003) provide information that is focused on tasks.…”

“…• Using a design-time tool to create concrete user interfaces for the required platforms • Using a run-time tool or process to render a concrete user interface Design-time tools are closer than run-time techniques to traditional user interface development and frequently encompass initial modeling, analysis and later development of multiple user interfaces. Such approaches include design patterns (Seffah & Forbrig, 2002), task models (Limbourg & Vanderdonckt, 2003;Paterno & Santoro, 2002;Molina et al, 2003), or offline analysis of user interaction (Pitkow & Pirolli, 1999). This approach provides good facilities for designing static user interfaces, but is challenged by mobility and unanticipated situations.…”

“…Molina et al investigated an approach to define user interface using models and then automatically generating different programs (program source code) for different platforms (Molina et al, 2003). Code generators in this work are created for a limited number of different programming languages/platforms; however, additional code generators can be added to accommodate additional languages or platforms.…”

Design multi-dispositivo em contextos de uso alternado e migração de tarefas

“…Para o exemplo de construção do modelo de tarefas, optou-se pelo uso da notação da ConcurTaskTree (CTT) criada por Paternò et al (1997) devido à sua grande utilização em trabalhos recentes para construção de interfaces multi-dispositivos (WINCKLER et al, 2002;MOLINA et al, 2003;CLERCKX et al, 2004a; PAQUETTE; SCHNEIDER, 2005; KLUG; KANGASHARJU, 2005). Essa abordagem oferece uma sintaxe gráfica para especificação de relações temporais entre atividades que captura o comportamento da interface em uma árvore de tarefas.…”
