Abstract:Motivation -Task analysis for designing modern collaborative work needs a more fine grained approach. Especially in a complex task domain, like collaborative scientific authoring, when there is a single overall goal that can only be accomplished only by collaboration between multiple roles, each requiring its own expertise. We analyzed and re-considered roles, activities, and objects for design for complex collaboration contexts. Our main focus is on a generic approach to design for multiple roles and subtasks… Show more
“…Indeed, proposed notations for modelling multi-user applications include: the COMM (COlaborative and Multi-Modal) notation and its on-line editor for specifying multi-user multimodal interactive systems [13]; CTML [26,3], a task-based specification framework for collaborative environments, consisting of a language and a tool for editing/animating CTML models; CUA (Collaboration Usability Analysis) [22], a modelling technique allowing designers to model the main features of a group work situation that will affect groupware usability. Other proposals along the same lines have been put forward by Penichet et al [21], van der Veer et al [25], Guerrero-Garcia et al, [8], Giraldo et al [9], Molina et al [15,16]. On the other hand, little has been proposed for collaborative task modelling tools.…”
Task modelling is a widely recognized activity when designing interactive applications. In this perspective, it is the meeting point between various stakeholders. However, most of the automatic environments that currently allow task modelling only support single users, thus limiting the possible interactions and discussions amongst them. In this paper we present Collaborative CTT, a new Web-based multiuser tool for specifying task models. The tool allows several users, who may even be physically separated, to work on the same model at the same or different time. Among its features, the tool includes mechanisms specific for this type of HCI modelling in order to support coordination, communication and mutual awareness among participants. We discuss the aspects we have addressed in designing the task modelling tool, its main collaborative features, and also report on user feedback gathered through formative tests.

“…We envision an ontology to analyse, describe, and support the future art ecosystem: with new roles, new objects, and new activities. Our conceptual framework is based on GTA [13], and we mainly consider to focus on development of the concepts Roles (with mandating and delegation), Objects (including tangible and intangible artifacts, and the context as an object), Tasks (as goal-triggered activities of (co-)creation, performance, and experiencing); and the multidisciplinary concept of values and forces that trigger action.…”

We introduce the rapid change of the visual art ecosystem, triggered by current science and technology development. ICT enables new multimedia based an interactive art forms, with an increasing variety of stakeholders. We provide examples of audience involvement, of immersion, and of braincomputer interaction as a new paradigm for participation. We point to the use of new material dimensions, as well as to expanding shared creation and cognition. We also point to opportunities to apply this development to accommodate special needs. In order to support the dissemination of these possibilities, we advocate the development of a task-modeling based ontology to describe, analyse, and support the evolving art ecosystem.
