Oil exploration has become a steadily growing business. This is due to the ever increasing demand for oil derivates in the international market. The extraction of this mineral, however, is not an easy process. It poses many hazards which may threaten the environment and the lives of workers at an oil well. In order to reduce the chances of accidents and failures, a continued training to the workers...
Research collaboration to model and analyze a complex 3D bio-molecular structure is often limited because of different time zones and locations of collaborations. A network-based real-time software collaboration tool for molecular modeling and its visualization was developed to overcome the problem. Collaborative Crystallographic Object Oriented Toolkit (Co-Coot) is an add-on of software called Coot...
This paper presents our development of tangible baseball supporting system based on social media technology for providing new experience of collaborative virtual cheering as future of digital media application. Main features of our system include compensation of network delay among participants' system, web mashup for exchanging information between physical world's spectators and virtual world's users...
This paper focuses on Collaborative Virtual Learning Environments, examining the state of the art in both open source and proprietary software. Issues pertaining to the use of open source CVLEs are discussed and a collaborative learning activity in Second Life is presented. Evaluation results assess the appropriateness of the Second Life platform in executing collaborative learning scenarios, and...
The use of multiple mobile devices is increasing in mobile learning, bringing a need for collaboration and resource sharing among participating pupils. This paper presents an approach that addresses information and resource sharing for mobile devices in indoors and outdoors settings. Our solution consists of aggregated mobile devices, forming organizations. These Mobile Virtual Devices (MVDs) provide...
This paper proposes a group synchronization control scheme with prediction in collaborative haptic play with building blocks. The scheme adjusts the output timing among multiple terminals and keeps the interactivity high. It outputs position information by predicting a future position later than the last-received position information by a fixed amount of time. It also advances the output time of position...
Mobile learning is considered the next step of online learning by incorporating mobility as a key requirement. Indeed, the current wide spread of mobile devices and wireless technologies brings an enormous potential to e-learning, in terms of ubiquity, pervasiveness, personalization, flexibility, and so on. For this reason, Mobile Learning is attracting significant research efforts covering a fairly...
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.
In this paper, we introduce an asynchronous collaborative support System introducing access control which can provide a flexible mechanism to store the current collaborative virtual environments (CVE) space, replay the past recorded CVE space and replace the current CVE by other past CVE space. Revision Tree with hierarchical 3D structure is visualized in space and operated by users to refer the past...
Virtual reality (VR) and data mining techniques are widely used in E-commerce. This paper discusses the integration of personalized recommendation system in 3d virtual shopping environment. Our approach has two obvious features: one is the personalized recommendation based on data mining technologies, which means the system enhances the customer desired product attributes by utilizing his/her past...
Virtual, mobile, and mixed reality systems have diverse uses for data visualization and remote collaboration in industrial settings, especially factories. We report our experiences in designing complex mixed-reality collaboration, control, and display systems for a real-world factory, for delivering real-time factory information to multiple types of users. In collaboration with TCHO, a chocolate maker...
This paper presents a collaborative mobile learning system: Mobile Virtual Campus (MVC) powered by the loction-based dynamic grouping algorithm. The MVC system has been developed to provide an innovative and interactive platform for online mobile learners by utilizing the location awareness and other built-in sensory compoments in mobile devices. On the platform, the mobile learners can learn collaboratively...
In many virtual world, we can enjoy shopping, watching movie, dancing, etc. However users enjoy these entertainments by oneself. Although, in virtual world, most of virtual services provide entertainments and social activities, there are no feedback to real world users. In this paper, we discuss about collaborative cheerleading method among virtual world users and Sensory effect using wearable haptic...
We present a prototype collaborative application for archaeology that allows archeologists from remote locations to interact in real time with 3D archeological models through a shared virtual environment using teleimmersive technology. At each location, a set of stereo cameras captures 3D video of the user in real time to create his/her avatar. The 3D data is sent over the network to the remote location...
Haptic sensory feedback has been shown to complement the visual and auditory senses, improve user performance and provide a greater sense of togetherness in collaborative and interactive virtual environments. However, we are faced with numerous challenges when deploying these systems over the present day Internet. The most significant of these challenges are the network performance limitations of...
In this paper we present a proposal for the creation of a European V-labs web space. In its essence it would result in an open online laboratory, with a primarily practical nature. In this laboratory students will have the opportunity to develop skills in the “know-how-to-do” area, enabling them to conduct a series of practical experiences in “try-out” philosophy that will substantiate and consolidate...
Computer Support Collaborative Work (CSCW) leads to many changes in the field of education and training. Aim at the problems of high expense, fixed training sites, restricted trainee number or time that existed in the widely used simulation system for using it to execute training in the field of education and training, the paper researched on the construction of Virtual Collaborative Training Environment...
The increasing widely application of Virtual Reality (VR) technology in the field of education provides novel means and methods for the modern teaching and education. The cooperative learning is a kind of teaching method that the specific teaching target cooperatively completed by multiple learners. The paper introduced VR technology into cooperative learning and constructed a Network Cooperative...
The real-time interactive distant education has been gradually applied to the actual teaching activities. The real-time interactive distance e-learning environment is urgent needed to support teachers and students to carry on collaborative learning over network and Internet. This paper presents an infrastructure for real-time interactive distant e-learning environment based on the VNC technology....
A collaborative education system using networked virtual reality (VR) overcomes differences of time and space between its teachers and students. The system can give cyber experiences in a virtual environment to students. We propose a collaboration system for experiment and education in biology. The proposed system uses a social computing based VR system called SecondLife. Students can learn basic...
