Physical Responses

To feel fear in a specific situation is a normal human experience, however, when this fear or aversion becomes excessive and disrupts the day to day life of an individual, it is said the person suffers from a type of anxiety disorder called phobia. One common type of treatment for phobias is exposure therapy (professionals expose the patient gradually to the feared object or situation).The objective of this paper is to implement a Virtual Reality system that simulates a real highway environment which allows to treat patients affected by highway phobias in a safe place.In cooperation with psychologists and psychiatrists, an action protocol was conducted to create and recreate the variables of the virtual environment to which the patient will be subjected to. Once this was completed, a Virtual Reality application was made that simulates a realistic highway which includes exits, overpasses, underpasses, and tunnels, among others.This hardware/software system will include Oculus Rift DK2 VR glasses in order to create an immersive environment that the patient can consider real and who will be able to interact with it. The performance of the vehicle was programmed through physical responses similar to reality as well as techniques of artificial intelligence in the vehicles that will interact with the one controlled by the patient. Also, this system includes a steering wheel, pedals, and a gearshift (manual or automatic).We think that this system will contribute to treating highway phobias, allowing the psychiatrist or psychologist to carry out therapy in an appropriate manner and through the support of technology the professional will have the ability to simulate the anxiogenic environment in a realistic manner so as to achieve effective treatment. In a future work, we must quantify the possible benefits of this type of VR system in phobia patients.

This chapter evaluates current possibilities for the attainment of a realistic context over the web by attempting to match the basic requirements of art history scholarship and teaching against what is currently offered and what can be expected in the future. It surveys some ongoing research in the field from the perspective of an observer and a user. The first section of the chapter discusses virtual reality modelling language (VRML) and describes a project of the Supercomputer Group at the Australian National University. This project aimed to model, using VRML, the Buddhist stupa at Borobudur. The chapter also discusses a second project which deals with the Piazza de Popolo at Rome and the reasons why this project did not employ VMRL. The second section of the chapter examines some other ways in which an ordinary lecturer may use various simple technologies to conjure context, and with more flexibility, detail and accuracy that VRML can ever achieve.

Immersive Environment

Virtual Reality (VR) is a rising technology that creates a computer-generated immersive environment to provide users a realistic experience, through which people who are not analysis experts become able to see numerical simulation results in a context that they can easily understand. VR supports a safe and productive working environment in which users can perceive worlds, which otherwise could be too complex, too dangerous, or impossible or impractical to explore directly, or even not yet in existence. In recent years, VR has been employed to an increasing number of scientific research areas across different disciplines, such as numerical simulation of Computational Fluid Dynamics (CFD) discussed in present study. Wind flow around wind turbines is a complex problem to simulate and understand. Predicting the interaction between wind and turbine blades is complicated by issues such as rotating motion, mechanical resistance from the breaking system, as well as inter-blade and inter-turbine wake effects. The present research uses CFD numerical simulation to predict the motion and wind flow around two types of turbines: 1) a small scale Vertical Axis Wind Turbine (VAWT) and 2) a small scale Horizontal Axis Wind Turbine (HAWT). Results from these simulations have been used to generate virtual reality (VR) visualizations and brought into an immersive environment to attempt to better understand the phenomena involved.

Peranan teknologi informasi menjadi hal utama yang harus dipenuhi untuk menunjang kegiatan dalam berbagai bidang kehidupan, tidak terkecuali bidang promosi suatu produk atau jasa. Dengan penggunaan internet penyampaian informasi mengenai produk yang dipromosikan menjadi lebih mudah dan dapat diakses setiap saat dan dapat dilakukan dimana saja. Medianya pun juga telah berkembang dengan berbagai macam kemudahan, salah satunya adalah media promosi berbasis multimedia. Teknologi virtual reality merupakan salah satu teknologi yang berbasis multimedia dengan memadukan berbagai elemen multimedia. Dengan penggunaan teknologi virtual reality tersebut diharapkan dapat menunjang media promosi agar lebih interaktif, efektif dan menarik. Aplikasi yang dikembangkan merupakan perpaduan antara teknologi virtual reality dengan website. Teknologi virtual reality akan menyajikan produk mobil yang dipromosikan melalui tampilan tiga dimensi yang interaktif. Teknologi tersebut kemudian ditanamkan dalam website sehingga memungkinkan pengguna dapat mengaksesnya kapan dan dimana saja. Teknologi virtual reality dikembangkan menggunakan VRML (Virtual Reality Modelling Language) dan software pemodelan 3D 3ds Max, sedangkan aplikasi berbasis web dikembangkan menggunakan bahasa pemrograman PHP, HTML dan CSS. Aplikasi tersebut juga didukung penggunaan basis data MySQL sehingga mempermudah user dalam mengolah data. Browser yang digunakan perlu dipasangi plug-in Cortona3D Viewer agar dapat menampilkan file tiga dimensi. Hasil dari pembuatan aplikasi ini adalah terancangnya sebuah aplikasi yang menggunakan teknologi VRML untuk media promosi mobil berbasis web. Hasil pengujian menunjukkan bahwa aplikasi ini menjalankan fungsionalitasnya sesuai dengan rancangan.

Immersive Virtual Reality (VR) has seen explosive growth over the last decade. Immersive VR attempts to give users the sensation of being fully immersed in a synthetic environment by providing them with 3D hardware, and allowing them to interact with objects in virtual worlds. The technology is extremely effective for learning and exploration, and has been widely adopted by the military, industry and academia. This current study set out to study the effectiveness of 3D interactive environments on learning, engagement, and preference. A total of 180 students took part in the study where significant results were found regarding preference for this new technology over standard educational practices. Students were more motivated when using the immersive environment than with traditional methods which may translate into greater learning and retention. Larger studies will need to be performed in order to quantify the benefits of this new, cutting edge technology, as it relates to understanding and retention of educational content.

Virtual Reality Modelling

Virtual Reality Modelling Language (VRML) is description language, which belongs to a field virtual reality (VR) system. The file, which is in VRML format, can be interpreted by VRML explorer in three-dimensional scene. VRML was created with aim to represent virtual reality on Internet easier. Development of 3D graphic is connected with Silicon Graphic Corporation. VRML 2.0 is the file format for describing interactive 3D scenes and objects. It can be used in collaboration with www, can be used for 3D complex representations creating of scenes, products or VR applications VRML 2.0 enables represent static and animated objects too. Interesting application of VRML is in area of automated workplaces simulation.
