In this paper, a method for hand posture recognition, which is robust for hand posture changing in an actual environment, is proposed. Conventionally, a data glove device and a 3D scanner have been used for the feature extraction of hand shape. However, the performance of each approach is affeected by hand posture changing. Therefore, this paper proposes the posture fluctuation model for efficient hand posture recognition, based on 3D hand shape and color feature obtained from a stereo camera. A large set of dictionary for posture recognition is built by various leaned hand images which were auto-created from one scanned hand image, based on plural proposed models. In order to show the effectiveness of proposed method, performance and processing times for posture recognition are compared to conventional method. In addition, we perform the evaluation experiment by using the Japanese sign language. © 2010 IEEE.

Mobile learning is considered the next step of online learning by incorporating mobility as a key requirement. Indeed, the current wide spread of mobile devices and wireless technologies brings an enormous potential to e-learning, in terms of ubiquity, pervasiveness, personalization, flexibility, and so on. For this reason, Mobile Learning is attracting significant research efforts covering a fairly variety of learning settings, from schools and universities to workplaces and cities. This research has evidenced that mobile technology can offer new opportunities for learners to learn inside and beyond the traditional instructor-oriented educational paradigm. However, mobile technologies are still in its infancy and many challenges arise. In this paper we analyze, from both learning and technological perspectives, the development of learning applications using mobile devices. To this end, proxy and proxy less architectures are considered as way to extend traditional virtual campuses with mobile clients. The objective is twofold: to access learning materials and to support learning activities. A prototype of a Virtual Campus is developed using MLE-Moodle -the Mobile Learning module of Moodle. The proposed Virtual Campus enables mobile clients to perform online learning activities and is a step towards achieving the “anytime, anywhere” paradigm.

Data mining algorithms have been proved to be useful for the processing of large data sets in order to extract relevant information and knowledge. Such algorithms are also important for analyzing data collected from the users' activity users. One family of such data analysis is that of mining of log files of online applications that register the actions of online users during long periods of time. A relevant objective in this case is to study the behavior of online users and feedback the design processes of online applications to provide better usability and adaption to users' preferences. The context of this work is that of a virtual campus in which thousands of students and tutors carry out the learning and teaching activity using online applications. The information stored in log files of virtual campuses tend to be large, complex and heterogeneous in nature. Hence, their mining requires both efficient and intelligent processing and analysis of user interaction data during long-term learning activities. In this paper, we present a bi-clustering algorithm for processing large log data sets from the online daily activity of students in a real virtual campus. Our approach is useful to extract relevant knowledge about user activity such as navigation patterns, activities performed as well as to study time parameters related to such activities. The extracted information can be useful not only to students and tutors to stimulate and improve their experience when interacting with the system but also to the designers and developers of the virtual campus in order to better support the online teaching and learning.

Computational intelligence generally comprises a rather large set of-in a wider sense-adaptive and human-like data analysis and modelling methods. Due to some superior features-such as generalisation, trainability, coping with incomplete and inconsistent data, etc.-computational intelligence has found its way into numerous applications in almost all scientific disciplines. A very prominent field among them are life sciences that are characterised by some unique requirements in terms of data structure and analysis.

Within the scope of information retrieval, efficient similarity search in large document or multimedia collections is a critical task. In this paper, we present a rigorous comparison of three different approaches to the image retrieval problem, including cluster-based indexing, distance-based indexing, and multidimensional scaling methods. The time and accuracy trade-offs for each of these methods are demonstrated on a large Corel image database. Similarity of images is obtained via a feature-based similarity measure using four MPEG-7 low-level descriptors. We show that an optimization of feature contributions to the distance measure can identify irrelevant features and is necessary to obtain the maximum accuracy. We further show that using multidimensional scaling can achieve comparable accuracy, while speeding-up the query times significantly by allowing the use of spatial access methods.

The project of E-Simulator is under way at Hyogo Earthquake engineering Research Center (E-Defense) of National Research Institute of Earth science and Disaster Prevention (NIED), Japan, which facilitates the world's largest shaking table. The E-Simulator uses the parallel finite element (FE) analysis software package called ADVENTYRECluster (ADVC) as a platform. In this study, we report the results of high-precision FE-analysis for simulation of collapse behavior of the 4-story steel building frame that is the specimen of the full-scale total collapse shaking-table test conducted in September 2007 at E-Defense. It is shown that elastoplastic dynamic responses can be estimated with good accuracy using a high-precision FE-analysis without resort to macro models such as plastic hinge and composite beam effect.

In this study, we design and present the novel wearable system with the interactive posture caption and recognition functions based on the non-vision over the ZigBee wireless sensor network (ZigBee-WSN). There are two type sensors, 3-axis accelerometer and clip type, to be employed in our wearable system. These sensors are arranged on user's four limbs such that the posture information can be gathered by them. Then, the posture information is transmitted to the data-controlling center over ZigBee-WSN. Finally, this center can analyze and distinguish various postures by our proposed algorithm through the friend user's interface to express. Our presented wearable system can distinguish out 28 kinds of hand postures and 13 kinds of leg postures altogether. Moreover, under our presented ZigBee-WSN system with small size, low-power consumption, and high-reliability characteristics, the data-controlling center can simultaneously tele-monitor the real-time body interactive postures of 8 persons, when the transmitting distance is less than 18 M and the package correct transmitted rate is more than 97.5%.

We are developing a measurement device by means of which gait information can be obtained that cannot be obtained by existent devices. We are also evaluating the effectiveness of the device in rehabilitation programs. The final goal of our work is to realize a space where patients can execute their rehabilitation routines at any time. In this paper, we report the outline of our novel measurement device. That is to say, we describe our realtime measurement technique for measuring the position and angle of the feet to obtain the gait information, as well as our method of presenting the gait information.

This paper proposes measurement site selection to visualize a wafer characterization map and also monitor wafer-to-wafer and batch-to-batch variation. In the manufacturing line of thin film devices such as large-scale integrated circuits, magnetic heads of hard disk drives and thin-film-transistor substrates of liquid-crystal projectors, several critical dimensions are generally measured and monitored for quality control. To monitor wafer-to-wafer and batch-to-batch variation, engineers control average and standard deviation of measured dimensions as statistical process control. To monitor characterization across a wafer, the engineers observe an sculptured surface as a wafer map. The paper presents a selection method to decide measurement sites across a wafer for both of the wafer map visualization and the process monitoring and examines their accuracies experimentally. © 2010 The Institute of Electrical Engineers of Japan.
