This paper presents a new virtual environment (VE) which employs a dynamic 3-D model of the classroom. It is based on powerful scientific visualization techniques and can be used as an effective aide in online virtual teaching. The learners enters the virtual model of the classroom as an avatar, navigate through it, zooms in or out as he or she wishes, changes his or her view point and perspective...
Movie therapy is a kind of means of art therapy which sprang up in the 21st century. It relaxes the viewers and releases their feelings and emotions by the way of showing a movie and making use of movie images, sound and the plots. As a result, the viewers' mental disorders and emotional traumas will be cured and analysed. This article mainly discusses the significant effect of movie therapy on stimulating...
The paper presents our preliminary work on developing a remote hardware development lab using mixed reality technology (mRLab). The mRLab allows a group of students to remotely and simultaneously work on a VHDL project with an FPGA development board. All lab objects are created in 3D and an interactive layer on the 3D objects is added to host learning information along with caveats to assist learning.
The rapid growth of modern water conservancy technologies over the past decades has dramatically increased the amount of multi-dimensional data generated in water conservancy activities. A GIS system for the classification, retrieval, visualization and integration of water conservancy data are in their infancy. The advent of high performance computers with fast floating point and integer processors...
Aiming at the difficulty of large weapon equipment operation training simulation, GL Studio software tool was adopted based on VR technology. A hierarchy structure was put forward to simulate all kinds of integrating equipment system, single equipment and operation unit. Key technologies including Model database structure optimization, LOD, operation unit motion simulation based on DOF and screen...
The advances made in both Human Computer Interfaces (HCIs) and in Mixed Reality (MR) systems during the past decade have opened the gates to countless new applications in fields ranging from applied science to fine arts. In fact, computers have evolved from boxes with which it was possible to interact solely using mice, keyboards and monitors, to become devices that permeate and intersect with the...
Application of virtual reality to tour guide training makes it possible to change the conventional teaching model into the communicative task-oriented one. The study describes the development and implementation of virtual reality in tour guiding to improve communicative skills and professional knowledge of tour guide candidates. An experiment analysis was to illustrate virtual reality is a unique...
Most of the systems for generating taste sensations are based on blending different chemicals appropriately, and there are less proven approaches to stimulate the sense of taste digitally. In this paper, a method to digitally stimulate the sense of taste is introduced and demonstrated based on electrical and thermal stimulation on human tongue. Thus, two digital control systems are presented to control...
In this thesis, a new virtual training system based on the virtual reality technology the form of desktop and the stimulation technology is introduced. It is able to satisfy the needs of the armored forces. By using the system, the teaching of the equipments, the virtual maintenance, the professional virtual training and the virtual tactical coordinated attack can be performed which are based on the...
We describe a virtual-reality framework for investigating startle-response behavior in fish. Using real-time three-dimensional tracking, we generate looming stimuli at a specific location on a computer screen, such that the shape and size of the looming stimuli change according to the fish's perspective and location in the tank. We demonstrate the effectiveness of the setup through experiments on...
The process of how we can achieve a low-cost infra-based interaction device informs of a motion tracking system is shown, that is in the first place, appropriate for personal use. The analysis for discovering the requirements of the intended system was based on gathering information about the proposed and other existing systems and then distilling the user and system requirements from this information...
Photorealism has been one of essential goals for virtual reality. The state-of-the-art techniques employ various rendering algorithms to simulate physically accurate light transport for generating the photorealistic appearance of scene. However, they still require a labor-intensive tone mapping and color tunes by an experienced artist. In this paper, we propose an automatic photorealism enhancement...
Sand models as used in military are thematic 3D representations of an area of interest which combined the information of maps with a more realistic 3D bird's eye view of the terrain. Sand models have been used for military planning and war gaming for many years as a field expedient, small-scale map, for planning and training of military operations. This, however increasingly fell out of favor with...
Using 3D computer simulations for training surgeons is not new, but neither is the use of e-learning for improving students knowledge acquisition. What we propose is to use 3D computer simulations in such a versatile way that those simulations could act as learning objects designed directly by those who own the experience we want to be transmitted. In order to achieve this goal, it is necessary to...
Based on the virtual realistic technical, the text discussed the feasibility of the virtual realistic technique can be applied to tour system constructive. Finally, on the foundation of the Earth platen, inquired the feasibility and key technique of virtual realistic technique in the travels system tapping.
Electronic games have an important role in the human development so we can face the world of constantly changing technologies. Considering that the most of games is grounded in the interaction through visual elements and that the most of alternate games for blind is less attractive to non-blind people, we have developed a prototype of a 3D environment with dense sound experience and haptic feedback...
It's better to evaluate information technology and its role in learning and Orientation with different concepts such as virtual education and its advantages and their difficulties in improving the quality of education. Virtual reality and its position in learning in one of the issues that is evaluated in this essay.
The boundaries between virtual reality and physical reality are becoming ever more blurred as activities in cyber worlds bleed into everyday life and sophisticated software now crosses the line from digital interaction to physical destruction. This paper examines what might be learned from the real-world exploits of the sophisticated software worm known as Stuxnet and from the speculations and extrapolations...
To solve the problem of the serious shortage of specimens in human anatomy teaching, virtual human anatomy teaching system was constructed by virtual reality technology. Based on the collection of traditional anatomical wall charts and CT, MRI and other kinds of medical images, three-dimensional model of human tissues and organs and various surgical instruments were established by VRML, 3D MAX, VTK...
