Incremental simulation modelling for Internet collaborative design

In order to support Web-based collaborative design in terms of transferring or updating models dynamically and efficiently, new incremental modelling and local updating strategies have been developed for simulation modelling application since simulation is more focused on visualisation effects than on geometry details. Based on an assembly connection concept, a drag-and-drop assembly method has also been proposed in simulation assembly. An assembly connection is defined as a group of assembly constraints and it makes assembly easier. A case study example is given to show the content of the proposed research

TOWARDS ENHANCED E-COLLABORATION IN ACADEMIA A HOLISTIC MODEL FOR DEVELOPMENT OF E-COLLABORATION SOFTWARE

Henriksson, Aron. Neculau, Andrei. 2008. Towards Enhanced E-collaboration in Academia. A Holistic Model for Development E-collaboration Software. The Royal Institute of Technology, Stockholm, Sweden. Information and Communication Technology.E-collaboration is an inherently complex activity that encompasses many factors that supplement the pivotal technical elements. This paper investigates the various aspects of e-collaboration from an academic viewpoint, and reiterates the call for a holistic approach towards e-collaboration research and development. Moreover, the use of collaboration tools by IT students is surveyed, which substantiates the belief that e-collaboration needs to be further promoted in academia. We present a conceptual model that hopefully can provide some guidance for further research on e-collaboration and development of e-collaboration suites.E-collaboration, Academia, Requirements, Boundaries, Holistic

Desktop multimedia environments to support collaborative distance learning

Desktop multimedia conferencing, when two or more persons can communicate among themselves via personal computers with the opportunity to see and hear one another as well as communicate via text messages while working with commonly available stored resources, appears to have important applications to the support of collaborative learning. In this paper we explore this potential in three ways: (a) through an analysis of particular learner needs when learning and working collaboratively with others outside of face-to-face situations; (b) through an analysis of different forms of conferencing environments, including desktop multimedia environments, relative to their effectiveness in terms of meeting learner needs for distributed collaboration; and (c) through reporting the results of a formative evaluation of a prototype desktop multimedia conferencing system developed especially for the support of collaborative learning. Via these analyses, suggestions are offered relating to the functionalities of desktop multimedia conferencing systems for the support of collaborative learning, reflecting new developments in both the technologies available for such systems and in our awareness of learner needs when working collaboratively with one other outside of face-to-face situations

Group Editer Using Graphical Operational Transformation

ABSTRACT KEYWORDS Graphical Operational transformation algorithm,G.O.T algorithm. 1. INTRODUCTION Collaborative editing system is which enables multiple users who reside remotely to share and edit some text / graphical / multimedia documents. This is an application area of Computer-supported cooperative work and it has been known for enhancing the efficiency and productivity of jobs and solving the physical limitation with virtualization[8] DESIGN REQUIREMENTS In this section we proposed and defined some of the underlying design requirements that we felt are important for a real-tim

An analysis framework for CSCW systems

Software toolkits are under development to help construct applications that support group-working. Toolkit developers adopt different approaches to group-work support in order to tackle different issues and a toolkit is commonly characterised by the approach adopted. It is difficult to compare toolkits because of this lack of apparent commonality and it is difficult to decide which toolkits meet specific application requirements. [Continues.

Revisión sistemática de la literatura sobre el desarrollo de sistemas colaborativos

Los sistemas colaborativos fueron concebidos para compartir información y coordinar actividades entre sus usuarios. Entendemos que existe una marcada complejidad tecnológica en desarrollar ambientes con estas características. Su diseño y desarrollo suele estar soportado por diversas herramientas y frameworks. Por otra parte, una revisión sistemática de la literatura es un medio para identificar, evaluar e interpretar todas las investigaciones relevantes disponibles a una pregunta de investigación particular. Es un proceso que consta de una serie de pasos secuenciales bien definidos que permiten conducir a una investigación. Motivadas en esto último, este trabajo desarrolla una revisión sistemática de la literatura con el fin de evaluar el estado del arte con respecto a aquellas herramientas de diseño disponibles para diseñar sistemas colaborativos.Facultad de Informátic

Frameworks for enhancing temporal interface behaviour through software architectural design

The work reported in this thesis is concerned with understanding aspects of temporal behaviour. A large part of the thesis is based on analytical studies of temporal properties and interface and architectural concerns. The main areas covered include: i. analysing long-term human processes and the impact of interruptions and delays ii. investigating how infrastructures can be designed to support synchronous fast pace activity iii.design of the Getting-to-Know (GtK) experimental notification server The work is motivated by the failure of many collaborative systems to effectively manage the temporal behaviour at the interface level, as they often assume that the interaction is taking place over fast, reliable local area networks. However, the Web has challenged this assumption and users are faced with frequent network-related delays. The nature of cooperative work increases the importance of timing issues. Collaborative users require both rapid feedback of their own actions and timely feedthrough of other actions. Although it may appear that software architectures are about the internals of system design and not a necessary concern for the user interface, internal details do show up at the surface in non-functional aspects, such as timing. The focus of this work is on understanding the behavioural aspects and how they are influenced by the infrastructure. The thesis has contributed to several areas of research: (a)the study of long-term work processes generated a trigger analysis technique for task decomposition in HCI (b)the analysis of architectures was later applied to investigate architectural options for mobile interfaces (c)the framework for notification servers commenced a design vocabulary in CSCW for the implementation of notification services, with the aim of improving design (d)the impedance matching framework facilitate both goal-directed feedthrough and awareness In particular, (c) and (d) have been exercised in the development of the GtK separable notification server

Patrones de integración de servicios groupware

La falta de asistencia en el diseño de integraciones de servicios groupware, ejemplos y arquitecturas que sirvan de guía y ayuden a realizar integraciones efectivas, conlleva a que cada vez que alguien necesite realizar una integración, la misma se lleve a cabo desde cero. Con lo cual los problemas que ya fueron resueltos por otras personas previamente se vuelvan a resolver desde cero una y otra vez. Una forma de abstraerse de los problemas inherentes de los diseños orientados a la implementación, es la utilización de patrones de diseño de software. Los mismos documentan soluciones ya probadas por medio de arquitecturas mínimas que luego pueden ser implementadas por medio de las tecnologías que se seleccionen. El objetivo de esta tesis es el estudio de los servicios groupware existentes, el desarrollo y la compilación de un catálogo de patrones de servicios groupware y de patrones de integración de servicios groupware.Facultad de Informátic
