In this paper we focus on two aspects: (1)the application of grid technology to allow a group of geographically disperse users to accomplish a given task collaboratively; (2) distributed scientific visualization through grid. Henceforth, we firstly describe some collaborative environments. Then, visualization techniques that can be implemented in grids are focused. These techniques can be integ...

Yang’s group has been actively working in the field of activity recognition based on mobile devices. Their work includes transfer learning for activity recognition and activity recognition for indoor daily-living activity recognition via mobile devices (see http://www.cse.ust.hk/~qyang/byarea.htm#Activity_Recognition) at location, action and goal levels. Yang was an invited speaker at IJCAI Con...

Cooperative activity involves collaboration and communication. Through the stages of collaboration, agents may play different roles either for performing domain tasks, or for forming decisions concerning the collaborative activity itself. Collaboration and communication can be enhanced if dependencies between agents’ intentions are captured. Role-specification is expected to be a vital factor t...

This thesis has two parts. The first part presents SharedActivity, a model for collaborative agents acting in a group. The model suggests mental attitudes for agents with different levels of cooperation and allows modelling of groups in which members are motivated to increase individual benefits. Unlike previous models, SharedActivity is suitable also for groups that do not have a joint goal. T...

With collaborative robots and the recent developments in manufacturing technologies, physical interactions between humans represent a vital role performing tasks. Most previous studies have focused on robot motion planning control during execution of task. However, further research is required for direct contact human-robot or robot-robot interactions, such as co-manipulation. In co-manipulatio...

Distance education has been offered to young students in Australia for about 100 years. Recently, information and communication technology has been introduced as a means to improve communication, but not all remote students have access to this new technology. This has made it difficult to arrange collaborative learning for distance-education students. In this student-focused study, more than 40...

This paper discusses the modelling of a Unit-of-Learning (UoL) (e.g. a lesson, a course) in e-learning. So far, the modelling of UoLs has been heavily focused on the definition and organization of contents. Currently, social and constructivist pedagogical approaches are demanding that learners get involved in more actual activities (e.g. solving problems, pairwork, group work). Educational Mode...

This study investigate the process of thinking required by individual learners in collaborative learning and the process of collaborative learning from the perspective of information processing and suggest a specific process of collaborative information processing with information externalization to make effective collaboration performance. In particular, the body of research mainly focused on ...

The Collaborative Virtual Environments (CVE) support the collaboration, communication and social interaction among users in a virtual space. In this paper we show a customizable CVE implemented on top of the Web to promote the collaborative learning in university courses. Our CVE allows the creation of different interaction environments according to the users’ needs. The design was focused on t...

Lockheed Martin Advanced Technology Laboratories (ATL), in conjunction with Lockheed Martin Maritime Systems and Sensors and Lockheed Martin Aeronautics Advanced Development Programs, performed a set of experiments in cooperation with the U.S. Navy involving collaborative, unmanned surface, and air vehicle mission execution. Our multi-domain, collaborative research focused on increasing unmanne...
