Come Closer describes a combined research and art installation using wearable technology and collaborative interaction to explore and challenge the sense of personal space and proximity to others. Participants become acutely aware of each other; aware of their presence in both physical and virtual space. They are encouraged to probe and investigate the boundaries that define personal space, to test them and to cross them. Interaction is defined entirely by position in a room, and the distances between them and others. The movements of the participants are logged and analysed for expected and unexpected behaviours.

In the factory automation, the communication information between the Control part and the GUI part usually contains the product, control and the operational information. The operations in the GUI part transfer the information between the user and the operational system part. Detailed analysis of the communication information and the process is an important factor to the system. And current software development process is changed over component and internet environments. In this paper, I was design and implement the control system for factory automation in component and internet environments. The component logic makes up the remote status view of the GUI communication modules which has associating the message interrupt method and the timer. This research aimed the IC test handler and this system can display on the web for review and analysis. The proposed method improves the analyzability by catching the operational data under various operation statuses. And it is able to come under a system manager’s observation.

This paper will discuss new cultural heritage-based communication and education models that are inspired by the ideas and arts of ancient Asia. Some examples of the models used will be given to show how knowledge from around the world can be shared. The goal of this research is to provide new data-based Communication Models that can be used to achieve education with a global background. Our research has just begun, and we are currently working at the theoretical level. The models we discuss here will be examined in greater detail during the next stage of our work.

The ARQ_RE model is proposed for supporting QoS resource errors detection-recovery in the situation-aware middleware. An example of situation-aware applications is a multimedia education system. QoS guarantees must be met in the application, system and network to get the acceptance of the users of multimedia communication system. There are several constraints which must be satisfied to provide guarantees during multimedia transmission. They are time, space, device, frequency, and reliability constraints. We propose a method for increasing reliability through an Adaptive Reliable QoS for Resource Errors (ARQ_RE) model for ubiquitous computing environments. The model aims at guaranteeing it through application QoS.

E-learning models are attempts to develop frameworks to address the concerns of the learner and the challenges presented by the technology so that online learning can take place effectively. So it usually used the item difficulty of item analysis method. But item guessing factor in learning results has to be considered to apply the relative item difficulty more precisely. So, for e-Learning system support to learner considering learning grade, it need item revision difficulty which considered item guessing factor. In this paper, I designed and embodied the learner’s tailoring e-learning system on the item revision difficulty. For an efficient design, I use PetriNet and UML modeling. In building this system, I am able to support a variety of learning step choice to learners so that the learner can work in a flexible learning environment.

The paper proposes a time-controlling algorithm for large-scale terrain rendering, which can’t be efficiently dealt with by LOD technique. In this algorithm, the terrain is divided and organized by quad-tree structure. Each terrain patch is assigned a certain time according to the total rendering time given in advance. The multi-resolution levels rendered are determined by visual apperception. To solve the T-junction and popping, an approach of stitching the level boundaries and geomorphing are respectively performed on GPU. The algorithm guarantees that each frame is rendered in preset time independent of the terrain or the eye position. The slow or jerky phenomena during roaming, which are usually caused by unstable rendering frame rate, can be successfully avoided. This terrain rendering algorithm is demonstrated in a massive terrain flyover application. The experiment proves that this algorithm is feasible and efficient.

As a new management tool in place of the barcode, RFID (radio frequency identification) applied in various industrial fields. The distinguishing feature of RFID is it’s ability for contactless information transmission, making it possible to retrieve information about previous activities from people without their knowing.

In this research, Geographical Content Display System Development and it’s tested and experimental use was conducted as one example of the use of RFID technology in the field of education. By using RFID technology in a hands-on workshop, we investigated how the data obtained could be analyzed and we show future possibilities.

We propose a rotational symmetry evaluation method that is used to determine the manufacturing technique of rotationally symmetric pottery like vessels. With the help of scanned 3D data of the surface of the vessel the symmetry is determined which is used to derive the manufacturing technique for this particular vessel. For example it can be determined whether or not a turning wheel was used to manufacture the vessel. Results for trditionally manufactured new vessels and ancient vessels are given and the applicability of the method in archaeology is shown.

Japan’s oldest Noh stage has been restored using CG. The painting of pine trees on a wall, which is severely damaged by the weather, has been restored and painted based on several historical and aesthetical investigations. The painting was texture-mapped onto the CG model giving the atmosphere of the stage when it was originally built. By using the CG Noh stage and motion capture data of a Noh play performed by a professional player, several kinds of edutaiment contents have been produced. Not only an ordinary character animation of a Noh play on the restored stage, but also walk-through animation of a scene which might be observed by the player during a play was created, which might be useful for introductory enlightenment.

In this paper, we propose an original three-dimensional (3D) computer-aided approach for surveying and mapping caves to get line drawings. By introducing 3D digital technologies into the line drawing, our approach has advantages in improving the drawing accuracy while cutting a lot of time costs. The 3D digital technologies are used to reconstruct accurate 3D models of real scenes. Then, the lines on the model surfaces are extracted by analyzing the model geometry. To demonstrate the advantages, we compare our approach with the traditional method usually used by archaeologists. Results show that our approach is much more convenient and accurate than the previous method.
