Hybrid Broadcast Broadband TV (HbbTV) is an industry standard for hybrid multimedia devices that are able to combine broadcast and IPTV delivery. This paper deals with companion screen devices, companion screen applications and communication of those applications with HbbTV terminal and its applications. Companion screen devices offer additional content to user and for pleasant experience communication...
Database is nowadays a crucial data storage for application needs. Currently, there are several existing popular databases such as relational database like SQL and non-relational database (i.e. NoSQL). However, both types have their own drawbacks which could not be utilized in both online and offline modes concurrently. Therefore, the authors develop a database that supports both modes especially...
Remote collaboration systems are a necessity for geographically dispersed teams in achieving a common goal. Real-time groupware systems frequently provide a shared workspace where users interact with shared artifacts. However, a shared workspace is often not enough for maintaining the awareness of other users. Video conferencing can create a visual context simplifying the user's communication and...
We developed a new email client which runs on the browser and is not dependent on a particular server, based on the Unhosted web application architecture. The client can connect to any standard mail server directly from the browser, using IMAP and SMTP protocols so that the user is not limited to the webmail clients provided by various email service providers. As our client runs in a browser, it is...
Current web-based collaboration systems, such as Google Hangouts, WebEx, and Skype, primarily enable single users to work with remote collaborators through video conferencing and desktop mirroring. The original SAGE software, developed in 2004 and adopted at over one hundred international sites, was designed to enable groups to work in front of large shared displays in order to solve problems that...
Web applications are increasingly adopting the client side storage rather than in server side. In fact, client side storage can be achieved by external plugins, libraries or HTML5 APIS. It ensures a high user's quality of experience, offline application usage and server load reduction. In this work, we focus on the privacy and availability of confidential data explored by HTML5 Local Storage API....
An interactive presentation is intended to support lecturers that need to enhance presentation expressions and gather real-time feedback from audiences while delivering their presentations. Our objective is to improve the efficiency of bi-directional communication between a lecturer and a large audience in presentations using a real-time questionnaire that the result is displayed on a shared screen...
Collaborative Web Browsing (cobrowsing) becomes more and more popular in commercial solutions. Cobrowsing allows different users to share a synchronized common view on a web page as well as sharing the interactions, such as mouse movements, highlighting text or mouse clicks, on this web page with each other. This makes it interesting for a wide range of use cases, such as customer relationship management,...
In this paper, we propose a new browser synchronization system, which supports elderly people and IT shortfalls to learn how to use on-line shopping services from a support person on a remote site. A key feature of the proposed system is to synchronize browsers without a centralized server, and it works even if user terminals are placed behind a NAT device. In order to traverse the NAT, the proposed...
We showed WFE, a real-time collaborative editing (RTCE) mechanism, in which a group of people can edit a web page on a web browser while members of the group share editing contents in real-time. In addition, we proposed applying WFE to a cloud computing environment, and we call the applied application WFE-S. The aim is to improve the system to have high scalability, elasticity, high responsiveness,...
We are developing WFE, a system for Real-Time Collaborative Editing (RTCE) for existing Web pages. We aim to enable several users to perform simultaneous modifications on existing Web pages in their browsers, while modified contents are reflected to other users in real-time. In this paper, we present the application of WFE to a cloud computing environment as well as its advantages. The environment...
Combining with virtual reality technology, we establish the multi-user virtual campus roaming system using Lyinux engine, realize interactive roaming, panoramic navigation and real-time chatting. This paper focuses on improving rendering speed of virtual scene and implementing the synchronization between multi-users. The experiment result shows that this system achieves good results in interaction,...
In this paper, we present SRCS, a system for Web browser Sharing and Collaboration that permits users within a group to share information and to cooperate based on the WWW at the same time. It is a pure browser-based solution without the involvement of any third-party platforms, servers changing and any other special client-side software installation. In addition, this paper shows that the implemented...
Ad hoc collaboration across organizational boundaries is gaining importance. In a networked world, organizations interact across diverse system landscapes with partners and customers. Traditionally, facilitating the collaboration of dispersed participants in heterogeneous environments required the same software on all client systems. This entry barrier can be lowered by leveraging the ubiquitous web...
XYLUS is a virtualized programming environment that addresses coder's mobility, hassle free coding environment, project management and team coordination. It aims to provide a coder or a team of coders to create, manage, develop, compile, execute and share a complete or partial set of development projects on the web without having any development and associated tools. This is mainly achieved through...
People spend a lot of time navigating on the web. When moving from one computer device to another, it would be useful to have access to the navigation data produced in the previous web session. In this article, a synchronization service of navigation data, called Browserver, is presented. It is responsible for keeping user navigation information (tabs, history, forms, cookies, etc.) so that it can...
Most of the phishing and pharming attacks are directed at the payment and financial services, with the purpose to steal online bank users' card number and password. This paper presents the design and implementation of a DNS based anti-phishing approach, which can be used to protect the card number and the password of the online bank users effectively, and prevent phishers and pharmers from stealing...
