Nowadays, collaborative systems and applications are widely used to allow multiple users to work together in order to achieve one same goal. In the field of virtual and augmented realities, such collaboration is often sought to effectuate complex activities in some relevant experiences. Users can share virtual objects, but most importantly, they use collaborative 3D interaction, visualize their objects...
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...
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...
We present a high-resolution interactive and collaborative data visualization framework capable of supporting multiple user interaction on a large screen display. The data visualization framework takes advantage of SAGE2 collaborative visualization workspace. SAGE2 is designed to take multiple displays and use them as one high-resolution multiuser workspace. SAGE2 users are able to access and manipulate...
Inexpensive displays make large, tiled displays attractive for visual analysis and collaborative investigation. Especially in multi-user environments, the increased space allows to better organize the findings and results and, therefore, helps to improve collaboration. One important requirement is that all users can navigate seamlessly on the whole display space, while employing the standard software...
We describe the Ignite Distributed Collaborative Scientific Visualization System (IDCVS), a system which permits real-time interaction and visual collaboration around large data sets, with an initial emphasis on scientific data. The IDCVS offers such a collaborative environment, with real-time interaction on any device between users separated across the wide area. It provides seamless interaction...
The main purpose of this paper is to present the made improvements to an innovative tool called Assessment Manager. These improvements are related with the implementation of analytic rubrics to help the instructors in the design of the assessment from the collaborative learning process completed by the students into Learning Management System courses. The assessment tool is part of a Teaching Assistant...
In this study, a cooperative UAV and UGV platform is proposed to obtain a wide range of visual information. The UAV recognizes a pattern marker on UGV and tracks the UGV without user control. It can provide wide range of visual information for a user in the UGV. The UGV by a user is controlled equipped with an aluminum board. And the UAV can take off and land on the UGV. The UAV uses two cameras;...
In medical science field, a large amount of medical data needs to be shared in order to assist doctors to make a diagnosis and give treatment collaboratively. Traditional medical visualization systems lack cross-platform access and collaborative visualization mechanisms, it is difficult to achieve remote access and collaborative interaction. This paper proposes a collaborative interactive visualization...
In programming courses, students are often asked to work in groups to write multiple programs. The existing Integrated Development Environments (IDE), however, do not encourage concurrent interactions among student programmers. Students often encounter difficulties in collaborative activities, sharing resources, reviewing code and discussing ideas, especially when the group cannot reach a common arrangement...
This paper introduces a new form of collaboration between school and family through the Electronic Handbook developed in our research work, which makes more effective the communication between both. Today is consensual in education sciences consider that collaboration between school and family is a key component in the process of learning and educational success. With the Electronic Handbook, the...
We hypothesize that information shared on social media can work for distributed software teams as a surrogate of the social awareness, that is information that a person maintains about others in a social or conversational context, gained during informal face-to-face chats. Hence, we have developed a tool that extends a collaborative development environment by aggregating content from social networks...
Social awareness, that is information that a person maintains about others in a social or conversational context, can contribute to counteract the lack of teamness in global software development and strengthen trust among remote developers. We hypothesize that information shared on social media can work for distributed software teams as a surrogate of the social awareness gained during informal face...
Free-hand drawing of diagrams or sketches is a natural form of expression in a variety of learning settings. It is easily supported by tablets or tablet PCs. Often such sketches are the basis of reasoning processes, also in collaborative scenarios. Sketches can indicate misconceptions. Therefore it is desirable to support a semantic interpretation of sketches integrated with other parts of a learning...
The proof of concepts (PoC) for MPEG-4 BiFS & LASeR mobile thin remote viewer has been already obtained. The present paper goes one step further, from PoC towards applications supporting multiuser collaboration in virtual environments. In this respect, the previous architecture is reconsidered and enriched with new components. This way, significant gains with respect to competitor remote viewer...
This paper presents an environment for molecular visualization with multi-projection and collaboration capabilities between geographically dispersed research groups. It was drafted a hardware and software architecture whose purpose is to reduce the negative effects of the delay in communication inherent long-distance networks.
Emerges in the sophistication of modern mobile devices encourages re-evaluations of mobile application design principles that were ideal only several years ago. As well, several mobile application design principles for facilitating collaboration are proposed. This paper then presents a system design that addresses all the discussed principles, creating a virtual meeting area in which participants...
In the context of multi-developer projects, where several people are contributing code, developers must deal with concurrent development. Collaboration among developers assumes a fundamental role, and failing to address it can result, for example, in shipping delays. We argue that tool support for collaborative software development augments the level of awareness of developers, and consequently, help...
Networked tiled display (NeTD) systems, which leverage low-cost display tiles connected by high-performance networking, enable the simultaneous visualization of multiple ultra-high-resolution media. In this paper, in order to pinpoint the performance bottlenecks, we first attempt to analyze the NeTD system performance under a remote visualization scenario. By modeling the NeTD system into computing/networking...
A novel product data management mode, CVPDS (Collaborative Visualization Production Development System), which is based on the cooperative design and visualization technology, is proposed in this paper. It also analyzes and establishes the system frame, discusses the key technology of cooperative visualization development and the implementing management flat; studies the realization method of 3D virtual...
