Companies and firms, nowadays, due to mounting competition and product diversity, seek to apply virtual cellular manufacturing systems to reduce production costs and improve quality of the products. In addition, as a result of rapid advancement of technology and the reduction of product life cycle, production systems have turned towards dynamic production environments. Dynamic cellular manufact...

This paper proposes the virtual scissors system using virtual hands. Users can cut virtual paper with their own hands. The purpose of this system is to make it easy to implement different tools by only changing parameters in software. Other purpose is to make system with small-scale input and output devices for general applications, for example, only using thin haptic information and force feed...

Virtual Medicine is an emerging and challenging field in Computer Graphics. Numerous visualization methods are used to model and render data of different modalities. In this paper, we present a new endoscopy system for virtual medicine. The main purpose of this system is to provide support for the planning of complicated endoscopic interventions inside of the ventricular system of the human bra...

This paper reports research into an interface between industry robots and Virtual Reality systems and creates a virtual robot for robot arm simulation, control language conversion, physical communication, robot networking and teleoperation control. The paper is based on an integrated manufacturing networking software which includes a PUMA robot, a Lansing welding robot, and CNC machines. The ai...

This paper presents the work of building a Grid workflow system on distributed virtual machines. A Grid Virtualization Engine (GVE) is implemented to manage virtual machines as computing resources for Grid applications. The Virtual Data System (VDS) functions as a Grid workflow engine. This paper designs and implements the Virtual Data System on distributed virtual machines, which are enabled b...

This article presents a novel method for controlling virtual audience system (VAS) in Virtual Reality (VR) application, called STAGE, which has been originally designed supervised public speaking training university seminars dedicated to the preparation and delivery of scientific talks. We are interested creating pedagogical narratives : encompass affective phenomenon rather than organizing eve...

We demonstrate a photo-realistic, interactive virtual human agent application, called the Virtual Human Interface that employs virtual people to provide digital media users with information, learning services and entertainment in a highly personalized, visually rich virtual reality environment. The virtual digital human is capable of seeing, detecting and recognizing one or multiple people in f...

The effective management and promotion of tourism can increase the Gross Domestic Product (GDP) of any country significantly. This paper presents the design of a simplified and generic architecture of a 3-Dimension (3D) model virtual walk-through for tourist centers and historical heritages. We believe that this model could be adapted for its implementation in any state or country. The countrie...

Omni-directional locomotion systems are yet of little advantage in virtual environments (VEs) with limited large display system, where users may experience visualless situations when they move in a direction that is not covered by the large screen. This paper presents a new omni-directional locomotion interface based on step-inplace movement and a smart-turntable system to impart users with the...
