To establish a universal communication environment, computer systems should recognize various modal communication languages. In conventional sign language recognition, recognition is performed by the word unit using gesture information of hand shape and movement. In the conventional studies, each feature has same weight to calculate the probability for the recognition. We think hand position is very important for sign language recognition, since the implication of word differs according to hand position. In this study, we propose a sign language recognition method by using a multi-stream HMM technique to show the importance of position and movement information for the sign language recognition. We conducted recognition experiments using 28,200 sign language word data. As a result, 82.1 % recognition accuracy was obtained with the appropriate weight (position:movement=0.2:0.8), while 77.8 % was obtained with the same weight. As a result, we demonstrated that it is necessary to put weight on movement than position in sign language recognition. © 2009 The Institute of Electrical Engineers of Japan.

The appearance of a product has led to a trend for a consumer to purchase a product. Some products have shapes or parts that don't fulfill the consumer's desires and needs. This mean that often, choice of a consumer is inspired by the shape of a product. Therefore, It might be interesting to study on perception of shape in terms of semantic associations. The aim of this study is to investigate people's perception on gender of 3D-shape in terms of semantic association such as "feminine" or "masculine". In this paper we observed the effect of variable base on perceiving gender kansei of 3D-shapes. To assess base-variance of 3D-shape, we examined whether convexity and concavity of base in the context of sharp and curved forms. Results of our psychophysical experiment will be very important and helpful in the kansei-driven design.

We present a novel reduction method of port-Hamiltonian systems by a renormalization group. The reduced system is suitable for a fast numerical calculation in a mesoscopic scale. Especially, we aim at the development of renormalized molecular dynamics with controls. First, we define a renormalized Hamiltonian with coarse graining. Next, we introduce a renormalized canonical Hamiltonian system. Moreover, we clarify the relationship between the renormalized Hamiltonian system and a Dirac structure. Finally, we obtain necessary conditions of boundary connections for each renormalized Hamiltonian system with different scales.

In this study, the multivariate probability distribution was investigated to develop the expert knowledge-based automatic sleep stage determination technique. The ultimate purpose is to develop adaptive automatic sleep stage determination algorithm for clinical practice. Gaussian distribution was adopted to realize automatic parameter selection while Cauchy distribution was adopted to estimate the parameter distribution. The different usage of multivariate probability distribution of Gaussian and Cauchy distribution presented effectiveness for automatic sleep stage determination.

This paper is concerned with the ∞ model reduction for linear parameter-varying (LPV) systems with both discrete and distributed delays. For a given stable system, our attention is focused on the construction of reduced-order models, which approximate the original system well in an ∞ norm sense. First, a sufficient condition is proposed for the asymptotic stability with an ∞ performance of the error system by using the parameter-dependent Lyapunov functional method. Then, the decoupling technique is applied, such that there does not exist any product term between the Lyapunov matrices and the system matrices in the parametrised linear matrix inequality (PLMI) constraints; thus a new sufficient condition is obtained. Based on the new condition, two different approaches are developed to solve the model reduction problem. One is the convex linearisation approach and the other is the projection approach. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed design method

Automatic electroencephalogram (EEG) interpretation based on referential derivation is easily interfered by ear lobe activation. In order to improve the quantitative EEG interpretation of dominant rhythm, bipolar derivation was proposed in this study. Coherence and phase obtained from cross spectrum analysis were used to determine the focus of dominant rhythm. Existence, peak frequency, amplitude and asymmetry of dominant rhythm were interpreted within the frequency band from 4 to 13Hz. The automatic interpretation of dominant rhythm based on bipolar derivation was compared with the visual inspection of electroencephalographer (EEGer) and showed good consistence.

EEG is represented to referential derivation with ear lobe reference and bipolar derivations for quantitative interpretation. When the ear lobe was activated, referential derivation with ear lobe reference was contaminated by ear lobe artifacts. In this study, the focus and extension of EEG components were estimated based on the cross spectrum of bipolar derivation. A referential derivation was constructed by choosing the electrodes out of the focus and extension area to obtain the distribution of EEG components. The constructed referential derivation can avoid the artifacts of ear lobe activation for quantitative EEG interpretation.

Optical mouse sensor for non-contact tactile sensing

Instead of functioning as part of a pointing device in computing, the optical mouse sensor is employed for non-contact tactile sensing in this study. The translation direction, the height and the category of an object surface can be sensed. It is an interesting idea to make an optical mouse sensor work in the manner of a human hand but in a non-contact way to "feel" the object surface. Based on the data table obtained from the experiments, the translation direction is calculated and the nonlinearity of the translation direction sensing is studied. It can be concluded that the resolution of an optical mouse sensor is direction-related. The feasibility of surface height measurement is analyzed and the optical mouse sensor can be used for crack detection on a plane surface. Height variation of 0.2mm can be detected. Besides, the feasibility of the optical mouse sensor for surface discrimination is proposed. © 2008 The Institute of Electrical Engineers of Japan.

Quantitative analysis and detection of abnormalities for electroencephalogram (EEG) recordings during evoked activities are essential for clinical diagnosis on neurological disorders. However, the process of interpreting EEG is time consuming and requires experienced electroencephalographers (EEGers). In this study, a method of automatic EEG interpretation during hyperventilation was proposed. The purpose is to provide a quantitative interpretation of EEG which is able to conform to EEGers' visual inspection. The final integrated results of automatic interpretation were compared with EEGers' evaluation, and showed high consistence.
