Virtual reality technology has been recently more intensively applied in chemistry. HaptiChem, which was developed in 2006, is one of the systems appeared in the early stage of this field. It is an intermolecular force display system, which makes it possible to touch and move molecules as feeling intermolecular force in a three-dimensional virtual space by using a haptic device. We introduced HaptiChem in chemical education. We held a high school chemistry class with 43 students entitled “Several Forces between Molecules” as being open to the media. The students learned about intermolecular force from a lecture together with experiences of the force using HaptiChem. They asked more questions about intermolecular force during the class than usual. Their answers to the questionnaires after the class indicated that the haptic system promoted curiosity and enhanced learning. The students could learn more effectively by combining with the active feeling with HaptiChem. The high-school teachers evaluated that such a system can more efficiently encourage students to learn and remember things by stimulating their sense of touch. The observations also suggested that a haptic device made it easier to establish three-dimensional perception, which is difficult only with 2D-display. This pilot experiment was performed on 15th March 2007. It was the first attempt at using it in the field of chemical education. The observation was done fourteen years ago. However, since the effectiveness of haptic device in chemical education has not been changed and the interests of the applications have been increased, we decided to report the data we observed, which should be still worth disclosing. We wish to dedicate the results to new developments now and in the future.

It is an intermolecular force display system, which makes it possible to touch and move molecules as feeling intermolecular force in a three-dimensional virtual space by using a haptic device. The functions and graphic display were designed as simple as possible for educational use, so that learner can easily grasp the meaning of the concept of molecular forces. We introduced HaptiChem in chemical education. We held a high school chemistry class with 43 students entitled “Several Forces between Molecules” as being open to the media.

Three Dimensional Display

An non-vertical stereoscopic 3-D display method by changing the parallax value of the parallax images is proposed. This method is capable of displaying virtual reality with high-immersion sense because the observing depth only depends on the parallax value. An experimental 3-D display system capable of producing high-immersion and virtual reality video images at 45 degree is developed. Furthermore, the effectiveness of the method is demonstrated by using this system.

This paper presents original solutions for creation of training complex learning cosmonauts to control a space jet pack on purpose self-rescue when emergency happens. An approach is proposed in which training is carried out in a virtual environment using virtual reality gloves and headset. The idea is that control of virtual space jet pack model is performed by interaction of virtual hands, copying movements of cosmonaut's hands, with three-dimensional model of jet pack's control panel. To implement the training complex, methods and approaches were developed for movement synchronization simulation of virtual and real hands, as well as simulation of jet pack's control panel and thrusters. Approbation of proposed methods and approaches was carried out as part of our virtual environment system VirSim developed at the SRISA RAS. Results obtained in the paper can be used to create training complex for learning cosmonauts to rescue when they accidentally separate from the International Space Station.

The Media

Indonesia is rich in culture, ethnicity which one example is the traditional houses that exist in each province. Introduce Indonesian traditional house to users by using information technology as a medium of information could be one way to preserve the nation's culture. Limitations of the media information about traditional houses that currently can only be enjoyed through pictures or visit the traditional houses directly make society can not know the traditional houses in Indonesia optimally. Therefore we need a media so that people can know more about traditional houses in Indonesia without the need to visit directly into sites or less information such as 2-dimensional images in the book. Application developed is combination between virtual reality and website. Application built using the waterfall method. The virtual technology is embedded in a website that allows users to access them anytime and anywhere. Aplication was developed using VRML (Virtual Reality Modeling Language) and 3ds Max modeling software, and using the programming language PHP, HTML, CSS, and MySQL database. The browser needs Cortona3D Viewer plug-in for displaying three-dimensional file. The results of making this application is an application that utilizes the VRML technology to display traditional house on the island of Java in three dimensions. The results show that this application runs in accordance with the design functionality that has been made.

And Training

The technological growth in the last years have conducted to the development of virtual reality (VR) systems able to immerse the user into a three-dimensional (3D) virtual environment where the user can interact in real time with virtual objects. This interaction is mainly based on visualizing the virtual environment and objects. However, with the recent beginning of haptic systems, the interaction with the virtual world has been extended to also feel, touch and manipulate virtual objects. Virtual reality has been successfully used in the development of applications in different scientific areas ranging from basic sciences, social science, education and entertainment. On the other hand, the use of haptics has increased in the last decade in domains from sciences and engineering to art and entertainment. Despite many developments, there is still relatively little knowledge about the confluence of software, enabling hardware, visual and haptic representations, to enable the conditions that best provide for an immersive sensory environment to convey information about a particular subject domain. In this paper, the state of the art of the research work regarding virtual reality and haptic technologies carried out by the authors in the last years is presented. The aim is to evidence the potential use of these technologies to develop usable systems for analysis and simulation in different areas of knowledge. The development of three different systems in the areas of engineering, medicine and art is presented. In the area of engineering, a system for the planning, evaluation and training of assembly and manufacturing tasks has been developed. The system, named as HAMS (Haptic Assembly and Manufacturing System), is able to simulate assembly tasks of complex components with force feedback provided by the haptic device. On the other hand, in the area of medicine, a surgical simulator for planning and training orthognathic surgeries has been developed. The system, named as VOSS (Virtual Osteotomy Simulator System), allows the realization of virtual osteotomies with force feedback. Finally, in the area of art, an interactive cinema system for blind people has been developed. The system is able to play a 3D virtual movie for the blind user to listen to and touch by means of the haptic device. The development of these applications and the results obtained from these developments are presented and discussed in this paper.

Biology Learning

Cells are central to the study of biology, yet many learners have difficulties understanding the abstract yet fundamental foundation of life. Research suggests that students' conceptions of cells are reinforced by current biology learning materials, which represent cells as two dimensional, highly ordered, and mostly empty. These models also inaccurately represent the number, location, and size of organelles. We examine the effect of an inquiry-based three-dimensional virtual reality (VR) game on high school students' mental models of cells. Students reported that the game was more interactive and engaging than traditional ways of learning about cells and attributed an improved understanding of cells to their game experience. Students' post drawings of cells depicted more types of organelles, increased density of organelles, and additional complexity than their pretest drawings, indicating a movement towards more accurate mental models of cells. However, students' scores did not improve on their factual knowledge about cells between the pretest and the post-game biology assessments. We discuss the implications of incorporating game-based approaches and new technologies such as VR into biology education.
