An increasing number of small and medium-sized enterprises (SMEs) use the Internet to support grow businesses. The application new technologies comes with inherent risks ever-changing cyberspace cybercrime. Previous research has shown that human factor remains core element in cybersecurity chain. Therefore, it is paramount employees receive effective training acquire a security mindset. This st...

In room–corridor building geometry, the corridor smoke temperature is of great importance to fire protection engineering as indoor fires occur. Theoretical analysis and a set of reduced-scale model experiments were performed, and a virtual fire model was proposed, to investigate the correlations between the maximum smoke temperature in corridors and the smoke temperature in rooms. The results s...

This paper describes a multimodal spoken language system, which allows users to furnish a virtual 3D living room. Speech and touch modalities are tightly integrated in a single user i nput turn. An advanced dialogue manager allows users to have a natural flexible style of interaction with the "virtual assi stant" (a talking head). The system is mixed initiative, with a system intelligence which...

We studied whether contextual information regarding an observer’s location within a familiar scene could influence the identification of objects. The context was provided by a 3D virtual living room, which allowed natural familiarization of the scene and objects together with a high level of interactivity. Results of initial self-orientation judgments obtained in the room showed observers could...

Real-time interactive virtual classroom is an important type of distance learning. However currently available systems are insufficient in the support of large-scale user access and cannot accommodate heterogeneous devices and networks access either. Furthermore, these systems are usually desktop-based, which means the teacher experience is completely different from teaching in a real classroom...

In this paper, computer modeling auralizations are validated by using articulation indexes. As it is well known, one of the main challenges in validating an auralization is how to find an objective metrics to evaluate its quality. The generation of acoustical virtual reality is done by the proprietary computer code RAIOS (Room Acoustics Integrated and Optimized Software), which includes sets of...

This paper examines a necessary condition for successful exploitation of a virtual environment (VE) in therapeutic intervention for fear of public speaking. The condition is that clients experience a degree of anxiety in the VE that is similar to what they would have been expected to experience in a similar real world setting. We refer to this as a "presence" response. The experimental study in...
