Objective: We aimed at improving group performance in a challenging visual search task via a hybrid collaborative brain–computer interface (cBCI). Methods: Ten participants individually undertook a visual search task where a display was presented for 250 ms, and they had to decide whether a target was present or not. Local temporal correlation common spatial pattern (LTCCSP) was used to extract neural...
Societal issues in cities concern many different stakeholders, all involved from different perspectives. In the context of deliberative democracy, this asks for a broad participation of stakeholders to influence and contribute to decision-making processes. We designed [X]Changing Perspectives, to explore how design might enrich deliberation with participatory sensemaking: the joint construction of...
The advance of technology has influenced the relationship between government and citizen. In this scenario, the convergence between digital democracy, crowd computing, information visualization, mining of social media and collaborative information systems can increase citizen participation in solution for social problems. The aim of this paper is to propose an application that provides a collaborative...
Emergency command and control centers (CC) are integrated facilities to assist and handle crisis situations. In these CCs, operators suffer both with information shortage and overload. This paper focuses on the information overload problem. Operators often do not have adequate access to information that may be relevant in the decision-making process. In many CC centers, information is stored without...
The design of key scientific facility is a comprehensive and complex activity with remarkable characteristics compared with the general product design and architectural engineering design. According to the requirement of collaborative management for the top managers and chief designers of the key scientific engineering, an information model of management-oriented digital mock-up (MDMU) is proposed,...
This paper presents a new method for collaborative argumentation construction, for remote participants working synchronously. A case study is presented to demonstrate the implementation of the concept of embedding an argumentation visualisation tool within a 3D virtual collaborative environment, for remote collaboration in addressing complex issues.
More than 10 years ago, Olson and Olson [1] analysed technology support for virtual co-location. They came to the conclusion that distance matters and that the analysed technology is not mature enough to enable virtual co-location. Olson and Olson stated that even future technology will struggle to enable virtual co-location, as providing awareness among co-workers and enabling co-reference as well...
The research in education system describes that students generally don't produce good results because of the use of traditional ways of educational system. It has been identified that the use of interactive technologies, constructive methods and appropriate interfaces has a great impact in improving creative education and learning. One of such interactive tool is multi-touch tabletop which helps teachers...
The key technologies for beyond visual range target allocation and multi-aircraft cooperative air combat based on the background of unmanned aerial vehicles air combat are detailed description in this paper. beyond visual range target allocation and cooperative air combat are the main forms of modem air combat, there are some key techniques to be studied in the process of the air combat, such as the...
Inflo is a web-based tool designed to support quantitative decision-making problems such as carbon calculators. Using the dataflow programming paradigm, Inflo provides an extensible environment for end-user programming. Inflo is built around the idea of collaboration and openness for opportunistic code-reuse and unplanned code sharing.
Although the application of sketch-based chart annotation is not pervasive in management, the use of sketchmarks can provide numerous benefits to managerial discussions. The collaborative use of chart annotations can support management teams in their decision making based on quantitative charts by visually eliciting and capturing interpretation processes, clarifying basic assumptions, stimulating...
In this paper, we propose a collaborative decision support platform that supports the product manager in defining the contents of a product release. The platform allows interactive and collaborative decision making by facilitating the exchange of information about product features among individual autonomous stakeholders, providing reputation-enhanced collaboration, ensuring a positive collaboration...
Group awareness information is important information for group work. It represents things such as group members' roles and responsibilities, their positions on an issue, their status, and the state of various group processes that group members know about when they work together. The group awareness information presented in this article is designed to capture group member activities and their behaviors...
This paper proposes a multi-agent framework for travel management decision support system that targets improved decision making, parallels human problem solving processes, and supports the major phases of decision making. A multi-agent system is a loosely coupled network of agents that work together to solve problems that are beyond the individual capabilities and knowledge of each agent. In travel...
Although significant progress has been made toward effective insight discovery in visual sense making approaches, there is a lack of effective and efficient approaches to manage the large amounts of insights discovered. In this paper, we propose a systematic approach to leverage this problem around the concept of facts. Facts refer to patterns, relationships, or anomalies extracted from data under...
This paper presents a human-centered vision of unmanned but crewed platforms, combining an onshore collaborative hybrid environment and an intelligent offshore oilfield. Computer science plays a major role in this vision since digital environments are paramount for the job. We discuss the importance of research in the fields of computer graphics, virtual reality and computer supported cooperative...
A meta-synthesis methodology based framework model was provided in this article to support the group decision-making process including steps of problem discussion process and consensus process. This model is composed of dual-scaling method based visualized group argumentation environment to support diverging form of thought and fuzzy preference relation based visualized consensus assessment environment...
