We perceive the real world through many senses. Most Virtual Reality (VR) display systems, however, only present the illusion to our visual and sometimes audio senses. Walk-in display systems, such as a CAVE, allow users to see their own bodies as they interact with virtual objects. Collaborative virtual environments CVE allow many users to share the same virtual experience including the manipu...

A virtual environment (VE) may represent a simulation of a real environment or of an artificial environment, such as in scientific visualization of data. For haptic interaction with a VE, the simulation has to compute some kind of geometrical relationship between positions of the haptic interface and objects in the VE, and then based on this geomety to compute an interaction force arising from ...

Virtual geographic environment (VGE) aims to express the real-world naturally, and support the complex geographic analysis. The data environment, fundamental of VGE, is expected to support the data management, analysis, sharing and application requirements of the massive complex geographic spatio-temporal data. In this paper, we summarized the key problems in the construction of the data enviro...

This paper presents a system for a shared virtual experience which was developed within a student project. The main idea is to have two or more persons at different locations, who can interact with each other in the same virtual environment. In order to realize this idea every person is motion-captured and wears a head-mounted display (HMD). The virtual environment is rendered with the Unity ga...

This paper reports on the performance of Distributed Haptic Virtual Environment (DHVE) applications deployed over policy-based IP networks. Our previous work reported that a best effort service in IP networks is inadequate for satisfying the Quality of Service (QoS) requirements of such applications. The current work tries to find out whether applying differentiated Services (DiffServ) satisfie...

the need for intercultural awareness and skills emerges strongly in both distance learning courses, and in social life in multicultural societies. the study of online language transactions is therefore an important aspect of the emerging culture and sociolinguistics of computer mediated communication. the research reported in this paper concerns perceptions held by students in an iranian univer...

with the advent of e-commerce, organizations are changingtheir business. most researchers believe that electronic trading can besuccessful when the public will trust in virtual environments. high degreeof confidence not only can meet customer expectations of a satisfactorytransaction, but can also eliminate certainty and perceived risk of onlinetransactions. the aim of this research is to study...

Virtual technology can be a useful tool for designing models of healthy urban environments. The resilience and sustainability in any urban environment involves the establishment and maintenance of the health of its citizens. The well-being of youth, the future workforce of every society, is a highly important consideration in the design of cities. Cities are only truly sustainable when the work...
