For applied research with practical CSCL scenarios there is no clear analytic-experimental approach to study changes in a changing context. We suggest and apply a method to map and visualise components that describe and measure impact and level of innovation of practical CSCL projects.
The present study aims to identify the intellectual structure of computed-supported collaborate learning (CSCL) so as to provide more insights into the research trend, the most influential scholars, categories, and regions. This paper analyzed the articles and conference publications derived from Web of Science (WOS) in the field of CSCL from 2006 to 2016. A total of 792 articles were selected and...
The propagation and dissemination of knowledge are extremely important elements for the collaboration of the country's scientific growth and development. One example is scientific collaboration networks, where interactions between two or more researchers occur, making it easier to share and perform tasks for a mutual purpose. The objective of this work is to analyze how the institutional scientific...
Currently, there is an increasing number of teachers from Higher Education Institutions who are looking for innovative methods, which allow the creation and management of teaching-learning spaces in a collaborative environment in which students are encouraged to interact, becoming the protagonists of their academic training. On the one hand, these institutions develop virtual courses in Technology...
Inter-vehicular communication (IVC) can be explored to build a live map of vehicles for enhancing collaborative vehicular applications related to traffic statistics, safety by accident prediction and prevention, and energy efficient route planning. For enhancing the abovementioned applications, a live map of vehicles associated with their communication identities (e.g., IP/MAC addresses) of other...
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...
Graph ranking is a promising technique for image retrieval, but its effectiveness is limited by the so-called semantic gap. To mitigate this gap, clickthroughs, which are helpful to perceive the visual content of images, are adopted by graph ranking models recently. However, few existing models take both sparseness and noisiness of clickthroughs into account, which are important in refining the clickthrough-based...
Communication with a robot using brain activity from a human collaborator could provide a direct and fast feedback loop that is easy and natural for the human, thereby enabling a wide variety of intuitive interaction tasks. This paper explores the application of EEG-measured error-related potentials (ErrPs) to closed-loop robotic control. ErrP signals are particularly useful for robotics tasks because...
With systems performing Simultaneous Localization And Mapping (SLAM) from a single robot reaching considerable maturity, the possibility of employing a team of robots to collaboratively perform a task has been attracting increasing interest. Promising great impact in a plethora of tasks ranging from industrial inspection to digitization of archaeological structures, collaborative scene perception...
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...
This research explores the effects of providing on-time automated assessment in a co-located collaborative system for Entity-Relationship design. In addition, students' perceptions about the validity and usefulness of this automated assessment, and its potential for reflection were analyzed. Thirty undergraduate students from computer science participated in the study, a quasi-experimental pre-post...
Polygon mesh has been widely used in various areas by virtue of its high verisimilitude and convenient interactivity. However, the prosperity of various display devices for mesh model may lead to a diversity and ambiguity of visual experience, which will considerably disturb the development of mesh. In this paper, the difference of visual experience for mesh model on VR device and monitor are analyzed...
We describe our experiences in the classroom using the internet to collaboratively verify a significant safety and security property across the entire Linux kernel. With 66,609 instances to check across three versions of Linux, the naive approach of simply dividing up the code and assigning it to students does not scale, and does little to educate. However, by teaching and applying analytical reasoning,...
Education system has a history of decades and from then the system is continuously evolving. Due to the vast paradigm there is enormous difference that makes traditional learning techniques boring to students. Learning is the act of acquiring knowledge or skills through study, experience or being taught. With the increase in technology, e-Learning has become word of mouth in the day to day life. This...
This work seeks to apply the emerging virtual and mixed reality techniques to visual exploration and visualization of earth science data. A novel system is developed to facilitate a collaborative mixed reality visualization, enabling both in-situ and off-site users to simultaneously interact with and visualize science data within mixed reality realm. We implement the prototype system in the context...
Through their experience with the ICERT REU program at the Texas Advanced Computing Center (TACC), two undergraduate students from the University of Puerto Rico and the University of Florida have initiated a collaboration between their home institutions and TACC exploring the possibility of using immersion to simulate perceptual disturbances. Perceptual disturbances are subjective in nature, and difficult...
We explore design approaches for cooperative work in virtual manipulation tasks. We seek to understand the fundamental aspects of the human cooperation and design interfaces and manipulation actions to enhance the group's ability to solve complex manipulation tasks in various immersion scenarios.
Recent recommender systems work well in terms of prediction accuracy, making use of a variety of features, such as users' personal information, purchasing history, browsing history and comments. However, traditional recommendation models have not made full use of item information and met difficulties with cold-start problems. On the other hands, visual information on item images is one of the most...
Dance performances use body gestures as a language to express emotion, and lighting and background images on the stage to create the scene and atmosphere. In conventional dance performances, the background images are usually selected or designed by professional stage designers according to the theme and the style of the dance. In new media dance performances, the stage effects are usually generated...
