Motion capture (MoCap) technique that can digitize a position and a posture as a function of time is widely used in order to create animation and CG. It is very difficult to measure all hand movements because one hand has twenty-seven bones and nineteen joints. Therefore, it has been impossible to record the finger movements of a sports player that are high in speed and in accuracy. In this study, we developed a high accuracy ‘Hand MoCap system’ by using the electromagnetic tracker that used small and light receivers. The cables of the receivers were replaced with special thin cables so as not to block the movements of the fingers. In this paper, we have measured dexterous finger movements for writing of six skilled calligraphy teachers and six inexperience students. In order to analyze the finger movements, we have to know the relative positions between the receivers and the nib of a pen. We also developed a calibration method to make a transformation matrix by using the motion capture data. From the comparison of the motion capture data of the skilled teachers and the inexperience students, it made clear that the movement of thumb is a key for writing neatly.

Operator training systems are essential tools for industrial systems, particularly for those where human error impacts on the safety of materials and personnel may cause significant financial losses. This work is part of a research project concerned with the study of operator behaviour when facing safety-critical situations. This paper focuses on the simulator architecture of an operator training system that is based on formal models, interconnected to form its simulation engine. It also discusses how the simulator engine communicates with the virtual world representation. The models were built using the Coloured Petri Nets (CPN) formalism. The simulator requirements include: a multi-platform collaborative and multi-user environment that allow for remote access; built with freeware software tools. The simulator built according to the architecture described on this paper, has been validated by a team of operators from the industrial context of application, i.e. electric systems.

Tele-immersive systems enable 3D interactive experience in a virtual space by bringing together objects born in physical and virtual reality environments that are geographically distributed. The immersive and interactive experiences are achieved by fusing real-time color plus depth video of physical scenes from multiple stereo cameras, displaying 3D reconstructions of physical and virtual objects, and tracking intersections of objects in a virtual space to facilitate interactions between objects. While tele-immersive (TI) systems have been attracting a lot of attention these days as a possible advancement of the current 2D video-based communication systems and of the virtual reality spaces, the challenges lie in limited resources available to satisfy the many requirements on a usable TI system. One of the TI challenges remains the quality of real-time 3D reconstruction of physical scenes. Our work is motivated by the lack of understanding of the importance of various TI system parameters on the quality which is critical for allocating limited resources to make TI systems useful. This paper investigates the impact of different quality parameters of TI systems on accuracy and speed of task executions in TI environments. We have designed a task of moving a virtual ball from an initial center position to a basketball basket close to top in a closed virtual cuboid space. Successful completion of the task involves localization, orientation and motion coordination for a human in TI environment. We report quantitative and qualitative measurements collected during task executions under simulated variations of 3D reconstruction quality parameters. Based on our experimental results with 29 subjects under 13 quality variations, we concluded that the most important parameter is the frame rate followed by the presence of of a human rendering rather than just an avatar representation of hands.

Long time data recordings by ambulatory devices became common today with widespread use of high capacity memories. In this study, this technology is used on home recording device especially designed for the pre-phase sleep apnea analysis at home before having certain diagnosis by proper polysomnographic examination in a hospital. Designing a portable recording system for clinically significant signals and analyzing an associated apnea detection algorithm are two significant and complementary studies carried out and reported in this paper. According to our aim, the Holter device discussed here is capable of recordings from many channels simultaneously but specifically for this study we consider just three signals namely ECG, breathing activity and oxygen saturation which are all significant for apnea detection in polysomnographic diagnostic phase. In apnea detection part we have initially studied the algorithm based on Hilbert Transform of ECG signal. The study also includes the comparison of three selected QRS detection algorithms (digital filter based, differentiation based and higher order statistics based) for ECG processing required for the Hilbert transform based apnea detection algorithm. Differentiation based QRS algorithm is preferred over other two due to its better performance on noisy ECG signals.

This paper describes identifying Tactile Walking Surface Indicators (TWSIs) with a white cane using an accelerometer. The vibration was examined by using an actual dot block. The effectiveness of the white cane was verified by examining the relation between the vibration and psychological strength. The experiment result revealed that there is no correlation between the psychological distance and the frequency spectrum.

A common strategy for extracting the feature and to preserve the global structure such as Principal Component Analysis, Two Dimensional Principal Component Analysis and Linear Discriminant Analysis have been used. These schemes are a classical linear technique that projects the data along the directions of maximum variance. To improve the performance, Locality Preserving Projection is used. The objective is to preserve the intrinsic geometry of the data, and local structure. However, Locality Preserving Projection has the weakness, restrictiveness to separate the non linear data set. A novel approach to separate non linear data set based on selection of non linear function maximum value by using Kernel is proposed. Kernel maps the input to feature space by using three non linear functions; the result of mapping will be selected the maximum value. To avoid singularity, the result of the selected value will be processed by using Principal Component Analysis. Furthermore, Laplacian is used to process the result of Principal Component Analysis to achieve the local structure. The performance of the proposed method is tested to classify smile stages pattern. The experiment result shows that, the proposed method has higher classification rate than Two Dimensional Principal Component Analysis and combining of Principal Component Analysis, Linear Discriminant Analysis and Support Vector Machine.

This work presents a prototype conversational system enabling human-computer interaction by using natural language expression. As an enhancement to well-known conversational agents like chatbots, in the proposed setting, human-machine dialogue is intended as a query/answer monotonic process aimed at minimizing semantic ambiguity within communication and delivering the required service. When user queries are ambiguous, hence semantically distant from the set of possible recognized interpretations, the system instantiates a dialogue with the user. In this case, the system provides suggestions on how to reformulate the query until a valid form is reached; this feed-back makes the dialogue-oriented interaction process resemble an ordinary chat (in the very restricted domain of system services) but with a machine interlocutor. The popularity of the chat as a synchronous communication instrument lets our proposal be suitable for a great variety of applications.

This paper presents a monitoring and forecasting system for Grid resources, based on Java and agent technologies. Performance monitoring, measurement and forecasting of Grid resources is an active research area, several researches and projects are studying and developing Grid information systems in order to provide users or schedulers with services necessary to determine which grid resource fulfills specific task requirements. Computational Grids are intrinsically heterogeneous and dynamic systems, these features make extremely difficult to build an information system that update itself automatically following the Grid configuration evolution. The technologies involved in our approach allow the implementation of a multi platform information system that is able to collect several node and network status data without explicit registration of new nodes or network configuration. The history of collected data is used by a resource broker to forecast the node and network performances. A graphical interface has been also implemented to show real time performance evolution and forecasting error and to allow users to select the best prediction algorithm.
