As the interest in Virtual Reality (VR) increases, so does the number of software toolkits available for various VR applications. Given that more games are being made with the Unity game engine than any other game technology, several of these toolkits are developed to be directly imported into Unity. A feature and interaction comparison of the toolkits is needed by Unity developers to properly suit one for a specific application. This paper presents an overview and comparison of several virtual reality toolkits available for developers using the Unity game engine. getReal3D, MiddleVR, and Reality-based User Interface System (RUIS) are analysed for VR interaction and display on multi-projection immersive environments like Cave Automatic Virtual Environments (CAVE)s. MiddleVR was found to have the highest performance and most versatile toolkit for CAVE display and interaction. However, taking cost into account, RUIS is the clear winner as it is available for free under the Lesser General Public License (LGPL) Version 3 license.

Biosignal interfaces provide important data that reveal the physical status of a user, and they are used in the medical field for patient health status monitoring, medical automation, or rehabilitation services. Biosignals can be used in developing new contents, in conjunction with virtual reality, and are important factors for extracting user emotion or measuring user experience. A biological-signal-based user-interface system composed of sensor devices, a user-interface system, and an application that can extract biological-signal data from multiple biological-signal devices and be used by content developers was designed. A network-based protocol was used for unconstrained use of the device so that the biological signals can be freely received via USB, Bluetooth, WiFi, and an internal system module. A system that can extract biological-signal data from multiple biological-signal data and simultaneously extract and analyze the data from a virtual-reality-specific eye-tracking device was developed so that users who develop healthcare contents based on virtual-reality technology can easily use the biological signals.

Virtual Reality is an upcoming trend in games and entertainment applications as the use of head-mounted displays becomes accessible for the mass market. These systems aim to provide immersive experiences, but they still do not offer a completely seamless experience, mostly due to sickness symptoms that can be experienced by the players. Cybersickness is one of the most critical problems that make the game industry fearful of higher investments. In this demo we developed a plugin for a commercial game engine to collect relevant data in a virtual reality game to use as a database to future research approaches to enhance user experience in head-mounted displays.

Virtual Reality (VR) is an upcoming trend in games and entertainment applications as the use of head-mounted displays becomes accessible for the mass market. These systems aim to provide immersive experiences, but they still do not provide a completely seamless experience, mostly due to sickness symptoms that can be experienced by the players. Cybersickness (CS) is one of the most critical problems that make the game industry fearful for higher investments. In this work, we made a critical study on the theories and causes of CS in virtual environments. We unified in a paper most of the leading hardware and software proposals to identify, quantify and minimize the main sickness problems. We also provide clarification about the most relevant measurement tools used to quantify the level of sickness for one or more players through specific questionnaires. We also developed a demo plugin for a commercial game engine to collect relevant data in a VR game to use as a database to future research approaches to enhance user experience in head-mounted displays.

Main Components

For most of the virtual reality system, one of the major aims is to provide a vivid interaction platform between the human operators and the haptic devices. Through the user interface, a skilful operator can control the haptic devices to accomplish relatively complicated jobs in real-time. Generally, the main components of a virtual reality system include dynamic simulations, haptic devices and the user interface, which is composed of virtual environments and visual equipment. This study focuses on developing a virtual tennis entertainment system with haptic behaviour. A parallel-type robot and a serial-type robot are employed as the haptic device handlers in this study, in which they are controlled directly by the operator's arm through the user interface. The operator can sense the change in virtual environment provided by dynamic simulations. In addition, the human operator can ‘see’ the change of environment during operation in real-time through the screen. A virtual spring model and a virtual damper model were constructed to simulate the process of tennis playing in this study. Experimental results verify the feasibility of the proposed virtual tennis entertainment system.

This paper looks to expand on the INEC 2016 paper ‘The future role of virtual reality within warship support solutions for the Queen Elizabeth Class aircraft carriers’ presented by Ross Basketter, Craig Birchmore and Abbi Fisher from BAE Systems in May 2016 and the EAAW VII paper ‘Testing the boundaries of virtual reality within ship support’ presented by John Newell from BAE Systems and Simon Luck from BMT DSL in June 2017. BAE Systems and BMT have developed a 3D walkthrough training system that supports the teams working closely with the QEC Aircraft Carriers in Portsmouth and this work was presented at EAAW VII. Since then this work has been extended to demonstrate the art of the possible on Type 26. This latter piece of work is designed to explore the role of 3D immersive environments in the development and fielding of support and training solutions, across the range of support disciplines. The combined team are looking at how this digital thread leads from design of platforms, both surface and subsurface, through build into in-service support and training. This rich data and ways in which it could be used in the whole lifecycle of the ship, from design and development (used for spatial acceptance, HazID, etc) all the way through to operational support and maintenance (in conjunction with big data coming off from the ship coupled with digital tech docs for maintenance procedures) using constantly developing technologies such as 3D, Virtual Reality, Augmented Reality and Mixed Reality, will be proposed.  The drive towards gamification in the training environment to keep younger recruits interested and shortening course lengths will be explored. The paper develops the options and looks to how this technology can be used and where the value proposition lies.

Haji merupakan rukun Islam yang kelima yang wajib dilaksanakan oleh seorang muslim yang telah mampu melaksanakannya. Manasik haji pada dasarnya adalah memberikan pelajaran atau informasi mengenai tata cara melaksanakan ibadah haji, sehingga tidak hanya terbatas pada calon jama’ah haji, biasanya masyarakat beragama muslim mempelajari tata cara melaksanakan ibadah haji dengan menggunakan buku-buku atau dengan cara memperagakan langsung dengan cara mensimulasikan tata cara ibadah haji sesuai dengan kondisi yang sebenarnya. Namun banyak kalangan masyarakat muslim yang enggan mendalami manasik haji, dikarenakan beberapa hal seperti tidak adanya waktu, dan kurangnya minat mempelajari dikarenakan kurang menarik dan tidak praktis. Dari hal tersebut sehingga muncul ide untuk membuat aplikasi simulasi manasik haji berbasis virtual 3D, aplikasi ini berisi tentang simulasi untuk rukun haji. Aplikasi manasik haji berbasis virtual reality ini dirancang dan dibuat dengan menggunakan software 3Ds Max dan unity 3D Game Engine. Hasil penelitian berupa aplikasi manasik haji yang dapat menampilkan simulasi virtual reality, yang meliputi simulasi tiba di bandara, Wukuf di Arafah, Mabit di Muzdalifah, Mabit di Mina, Jumrah, Tawaf, Sa’i dan simulasi Tahallul. Dengan adanya aplikasi ini diharapkan akan terjadi peningkatan minat masyarakat dalam mempelajari tata cara pelaksanaan ibadah haji.Kata kunci : virtual reality, manasik haji, simulasi, 3D.

AbstractRecent advances in the field of web technologies, including the increasing support of virtual reality hardware, have allowed for shared virtual environments, reachable by just entering a URL in a browser. One contemporary solution that provides such a shared virtual reality is LIRKIS Global Collaborative Virtual Environments (LIRKIS G-CVE). It is a web-based software system, built on top of the A-Frame and Networked-Aframe frameworks. This paper describes LIRKIS G-CVE and introduces its two original components. The first one is the Smart-Client Interface, which turns smart devices, such as smartphones and tablets, into input devices. The advantage of this component over the standard way of user input is demonstrated by a series of experiments. The second component is the Enhanced Client Access layer, which provides access to positions and orientations of clients that share a virtual environment. The layer also stores a history of connected clients and provides limited control over the clients. The paper also outlines an ongoing experiment aimed at an evaluation of LIRKIS G-CVE in the area of virtual prototype testing.
