In this study, we propose a new method to detect microsaccades using a order-statistic low-pass differentiation filter.The usual method need to trial and error processes to decide the threshold value. Our method can detect microsaccades over 90%accuracy by applying a dynamic threshold technique without any parameter tuning separately for each data.

This study proposes a mathematical model of retinal ganglion cells considering peripheral characteristics to evaluate the influence of miniature eye movements. Simulation results show that microsaccades enhance the response of M type ganglion cells at some distance from central fovea. This indicate that microsaccades play important roles in peripheral perception.

The purpose of this paper is to get a model of categorical color perception . It is difficult to obtain accurate a neural network model for all categories because disparity in number of training data for each category. Thus, weights of training data are configured for each category to solve this problem.

We measured the preferred viewing distance for a number of different screen sizes, including monoscopic and stereoscopic images. The preliminary results indicate: a) the preferred viewing distance (PVD) remains at 2.0H, and b) the minimum viewing distance (MVD) remains at 1.3H as larger picture size than 75 inches.

This paper presents the results of subjective evaluation of metallic appearance for estimating the determinants of material perception. Images of a ball to which have various parameters are generated using CG software. Subjects experiment is conducted using the images, and a degree of metal likes is decided based on its results.

We have proposed a framework for fast listening methods that are the equivalent of skimming of textual information. Since the speech is time-sequential information, it is difficult to gain an overall understanding in a short time. So, we have developed an adaptive speech rate conversion technology for efficient overview listening.

Using Android Devices, we have developed a system that presents speech content using sentences containing kana and kanji characters that are presented with pronunciation alongside each kanji character. The pronunciation displayed can be set to match a reader's literacy level. We distributed a construction, action, and a function.

We investigated into the effectiveness of signboards with scent. When presented with a picture along with the scent associated to it, the subjects tended to pay more attention to the picture and exhibited improved memory retention. The increase in skin conductance was also observed, suggesting that the subjects experienced emotional excitation and mental strain.

This paper describes modeling of driving system of wire driven haptic display. We discuss the characteristic of driving system composed of wires and motors. The modeling system becomes possible to evaluate the specification of the device in basic design phase and to correct the error margin in haptic rendering phase.
