Since the publication of the first FTIR multi-touch interaction system [1], the public attention for the field of Single Display Groupware (SDG) has been rising constantly. Lately, former SDG systems with multi-interaction capabilities like DiamondTouch [2], reacTable [3], or Microsoft Surface [4] have been followed by promising systems, i.e. ThinSight [5] and MightyTrace [6]. The latter integrate their tracking technology into commercial liquid crystal displays (LCD), and thus drastically reduce the space requirements. Some recently published work [7] also conveys a trend to support industrial-oriented tasks as systems like BUILDIT [8] did some time ago. We present a traffic training simulator concept based on discrete event simulation to ensure realistic traffic behavior, adequate visualization, and a user centered interaction concept on an SDG system to support training activities for policemen. Within this environment, policemen are able to train their behavior and the adequate choices under different traffic situations much like other professionals train their standard procedures, e.g. pilots in a flight simulator. Such a training environment will give the possibility to learn offline about important characteristics of intersections based on historical data like system stability, incident handling, or additional improvement potential.

This paper presents the design and testing of an image contour display system with vibrotactile array. The tactile image display system is attached on the user's back. It produces non-visual image and permits subjects to determine the position, size, shape of visible objects through vibration stimulus. The system comprises three parts: 1) a USB camera; 2) 48 (6×8) vibrating motors; 3) ARM micro-controlled system. Image is captured with the camera and the 2D contour is extracted and transformed into vibrotactile stimulus with a “contour following” (time-spatial dynamic coding) pattern. With this system subjects could identify the shape of object without special training; meanwhile fewer vibrotactile actuators are adopted. Preliminary experiments were carried out and the results demonstrated that the prototype was satisfactory and efficient for the visually impaired in seeing aid and environment perception.

Simulation of variable spatiotemporal-scale forest growth is a trend in virtual forest simulation field. Most existing virtual forest simulation systems have relatively fixed structure and weak reconstruction capability. Besides, there is much duplication of work between different-granularity forest simulation systems. Therefore, this paper presents component-based forest simulation system architecture so as to achieve rapid construction of multi-granularity forest simulation system. We adopted the component technology to build a loosely coupled architecture, and conducted research on component extraction, classification, design and other key technologies. On this basis, we analyzed characteristics of different-spatiotemporal-scale forest scenes, and achieved the rapid construction of different granularity forest simulation systems through component assembly.

Augmented Reality applications have already become a part of everyday life, bringing virtual 3D objects into real life scenes. In this paper, we introduce “Virtual Roommates”, a system that employs AR techniques to share people's presence, projected from remote locations. Virtual Roommates is a feature-based mapping between loosely linked spaces. It allows to overlay multiple physical and virtual scenes and populate them with physical or virtual characters. As the name implies, the Virtual Roommates concept provides continuous ambient presence for multiple disparate groups, similar to people sharing living conditions, but without the boundaries of real space.

Haptic sensations can be induced without requiring haptic devices through pseudo-haptic feedback by the influence of another sensory modality, such as vision. In this paper, we propose two novel approaches that combine pseudo-haptic feedback with visual and tactile vibrations in order to augment the overall haptic sensation. We would like to investigate the integration of pseudo-haptic feedback with vibratory feedback. The first technique enhances pseudo-haptic textures with a stripe pattern that provides a vibro-tactile stimulus. The second technique modulates the perceived material stiffness of a virtual object using vibratory models for visual and tactile feedback, introducing novel pseudo-haptic effect based on visual vibrations.

We conducted experiments to investigate the human ability to discriminate fabrics. In the first experiment, we examined the discrimination ability at the neck and at the fingers, and found that subjects typically could not discriminate the size of a knitted stitch at their necks as precisely as at their fingers. This result is reasonable considering that the density of human mechanoreceptors is higher in the fingers. However, many people are sensitive to the texture of mufflers. We then conducted another experiment to find the rate at which subjects felt a fabric was scratchy. In this case, we found that the subjects tended to discriminate the kind of material more sensitively at their necks than at their fingers.

Simulation of natural phenomena in a virtual environment is an intriguing and mathematically complex open research area. The main contribution of this research is to simulate the behaviour of hornets by exploring the dynamic behaviour of swarm of simple agents. Swarm has been formed with collection of simple agents where each agents acts relatively independent from other agents in the environment. Here the swarm intelligence is gained through Particle Swarm Optimization(PSO) algorithm combining with principles of flocking behaviour which can be used in entertainment industry as well as in military applications.

A wide range of systems are composed of controller as input device and monitor (output device) for displaying the outputs. Remarkable developments of game controller have taken place in the field of entertainment. However, the button type controllers are a great obstruction to beginners because the operation efficiency widely varies depending on the proficiency level. By using soft materials, controller with superior crash-worthiness can be developed. This will even allow the user to perform activities such as throwing etc. Furthermore, operations utilizing sense of touch and force of many parts can be accomplished by inputting the force related information required to transform the shape of the controller. This report is regarding development of a soft-body controller made up of soft material that can be thrown and also allows input of information related to force based on shape-transformation.

Research collaboration to model and analyze a complex 3D bio-molecular structure is often limited because of different time zones and locations of collaborations. A network-based real-time software collaboration tool for molecular modeling and its visualization was developed to overcome the problem. Collaborative Crystallographic Object Oriented Toolkit (Co-Coot) is an add-on of software called Coot. Co-Coot enables multiple synchronous collaborative researchers at different locations to observe and manipulate their shared models of molecules simultaneously in realtime for better communication and collaboration. Co-Coot also provides additional collaborative features of sharing and transferring temporary working data of the model. It can also be used as an educational tool by providing with real-time feedback and demonstrations.

The multi-domain virtual environment is an important research area of the distributed virtual reality. However, frequent interaction, great quantity of messages and the discrepant need of each individual simulation domain resulted in numerous redundant messages. In this paper, we propose a Publish/Subscribe based correlative matching method for multi-domain virtual environment. This method focus on data filtering of domains' gateways in addition to the DDM scheme. The paper introduces the correlative matching algorithm, the binary representation and the matching method which based on publish/subscribe relationship. Analysis and experiments show that this new solution effectively reduces the redundant data transferring among gateways, thus greatly enhances the performance of the virtual environment, and that the cost of matching method is relative small in multi-domain virtual environment application.
