In development of a handy information device, for example, a smart phone, the repetition of prototyping, evaluating and correcting are indispensable for ensuring stability of grasp, operationality and non-fragility. Because those properties are not able to be evaluated by common digital product development systems. In addition, operationality of these products greatly changes by shape of product, arrangement of buttons, output of implemented programmes etc. However, there is no system that makes the user evaluate efficiently and totally such a product. Therefore, the goal of this research is to develop the augmented reality system with the tangible interface that can tactually present the outline shape of the product model for efficiently product development.

Emerging augmented reality and tangible user interface techniques offer great opportunities towards delivering rich, interactive prototypes in product development. However, as most of these are evaluated outside the complexity of. Design practice, little is known about the impact of these prototypes on the resulting product or the process. As a part of a larger multiple-case study approach, this study attempts to explore cues to characterize and improve the design practice of information appliances by performing a retrospective case study. The development of a handheld digital oscilloscope was chosen as an exemplar, embodying complexity in both form giving, interaction and engineering aspects. Although some of the employed techniques have grown obsolete, reflection on this development project still forecasts interesting and useful issues that should be considered while developing new design support methods and techniques.

Driving simulator is an important facility for driving safety study. This paper introduced three well-know large-scale moving-base driving simulators and two fixed-base simulators. Driving simulator has a broad range of applications of driving safety study, from driver’s behavior study to vehicle device and technology study, the paper reviewed seven main research aspects including behavior study, driver education and training, transportation infrastructure, medicine and therapy, ergonomics, Intelligent Transportation System, and administrative method.

In this paper, an integrated virtual assembly simulation experiment environment of interactive workplace planning, assembly process simulation and ergonomics evaluation is built and it provides a new ways and means for interactive and visualized workplace design and process planning. A simple and effective method of measuring the movement manipulating data of operator is presented and can provide data source for ergonomics evaluation of the operator. In order to obtain these data in VE, movement data of the operator in real environment is transformed into VE and is related with virtual objects by the corresponding relation between VH and real hand (RH). Based on these data, the operator’s fatigue index and energy consumption can be calculated. The conformability and fatigue of users for repetitive assembly operations are quantitatively evaluated to reduce the health problems of operators because of unreasonable layout and repetitive work.

Massively Multiplayer Online Games (MMOGs) are no longer just games. “Metaverses,” a variant of these games, which include Second Life and Active Worlds, represent some of the most immersive, interactive possibilities for learning, simulation, and digital design in use today. They also increasingly blur distinctions between work and play, as well as user and designer, prompting questions about the nature and practice of virtual design, that is, design that is practiced inside virtual reality by and on 3D avatars. This paper describes results from a qualitative study of collaborative design practices within Second Life, a popular metaverse and design environment. We analyze design processes, including the artifacts that avatar-designer create and use in the design activities.

This paper introduces a concept of augmented reality haptics close to its vision equivalent, namely the blending of information between direct input, measured in the real world, with virtual ones, computed from a VR simulation, related to the explored real world. Hence, we propose blending functions enabling the transition of haptic features, applied for forces and for position switch. Finally, to demonstrate our concept, a tele-operative system dedicated to the tele-touch-diagnosis, is presented and used for scenarios of comparison between real and virtual objects as well as experimental results.

This paper presents a method for cultural heritage exhibition. A design scheme of multi-projection screens based digital storytelling system for the Grand Canal Museum in China is introduced. The task of this system is to exhibit a famous Chinese painting on a large display wall dynamically. In order to display this painting in a large display wall, the painting have to be repainted with very high resolution and segmented into many smaller tiles for being projected onto the large wall. Additionally, in order to make this static painting attractive and charming, the technology of digital storytelling is used. So a script called is composed elaborately by us to show the magnificent scene along the Grand Canal.

is an interactive digital environment that is meant to show the short-, medium- and long-run effects of psychoactive substances on the human organism. Its purpose is to increase the users’ knowledge of these effects, which is often based on misconceptions and legends, and to provide a feedback on their level of information, with preventive purposes. These kind of educational games have the advantage of being more persistent, ubiquitous, informative, anonymous and multi-medial than a normal lecture. However, they have to be perceived as credible and plausible to the user in order to be persuasive, especially since the target is constituted of young people familiar both with the technology and with the subject. In this paper, we will describe the process of designing and evaluating the videogame in the field, as well as the insights provided by the participants who took part to the evaluation.

In this paper, we apply augmented reality to provide pottery design experiences to the user. Augmented reality offers natural 3D interaction, a tangible interface, and integration into the real environment. In addition, certain modeling techniques impossible in the real world can be realized as well. Using our AR system, the user can create a pottery model by deforming a virtual pottery displayed on a marker with another marked held by the user’s hand. This interaction style allows the user to experience the traditional way of pottery making. Also provided are six interaction modes to facilitate the design process and an intuitive switching technique using occlusion-based interface. The AR pottery system can be used for virtual pottery prototyping and education.

This paper presents an optical see-through (OST) Augmented Reality (AR) system for the treatment of phobia to small animals. Our group has already presented two AR systems for this treatment. The first system was a video see-through (VST) AR system. The second one was a markerless AR system. And now, we present a third version using an OST approach. To check whether the OST AR system is more or less effective than the OST AR system, we have carried out an experiment comparing both systems. In this paper we focus on the anxiety level of participants during the experiment. Results show that both systems provoke anxiety in participants even if they do not have fear to cockroaches/spiders. OST AR system provokes slightly more anxiety than the VST AR system.
