As aging society problem goes severe In not only Japan but also the whole world, more and more attentions are attracted to the social and welfare fields. Many researches on science and technology for elders are implemented in rencent years. With the background, there are a lot of needs for techonologies with novel features for improvement. In this paper, a control method with attractive features for the actuator of Ultrasonic Motors (USMs) is introduced. In medical and welfare areas, the USMs are expected to play more important roles owing to their special characteristics. In this research, an intelligent PID control method using Neural Network (NN) combined with type Particle Swarm Optimization (PSO) is developed for the control of USM. In the method, the intelligent controller is designed based on variable gain type PID control using NN. The learning of the NN unit is implemented by the PSO. The gains of PID control are adjusted by the proposed method in real-time. The effectiveness of the method is verified by experimental results.

To provide a better user experience, we have to consider type of device and place. It means that the contents should have capabilities to be converted into several types. In this paper, we suggest a scheme to provide still-cut images from the moving images without user's or contents provider's effort. We also show you how to adapt the scheme to the web through demonstration.

Estimation of whether visual fatigue caused by display operations on personal computers will be tolerable is very important to keep one's eyes healthy. Newly described are the mathematical model analyses of temperature rises on the eyelids of each operator and interpretations allied to this matter. Note that the temperature rises of this mode were optically sensed to have been caused by visual fatigue due to visual accommodation change during display operations on personal computers.

This study proposes a story creation approach for developing a sensor/home network application. In this approach, a device on a network is regarded as a character in a story. In this respect, the device's state and action is defined by the description of the character with a natural language corresponding to an ECA rule. Transmitting messages among the devices are dealt as conversation among the characters. This paper will show the detailed concept and an actual application development environment using this approach. The result of the experiment, in which 18 children and six adults were involved, showed the usefulness of the approach.

In this paper, we assess the quality of experience (QoE) about the operability of a haptic interface device for work in which a user operates an industrial robot with a force sensor at a remote location by using the haptic interface device while watching a video. We treat work of putting a metal rod attached to the tip of the industrial robot arm into a hole, and we demonstrate how much the operability is degraded owing to the network delay. To improve the operability, we also carry out the adaptive reaction force control, which we previously proposed, and investigate its effect.

We have developed Flying Cloud Server, which is a drone equipped with a wireless LAN base station and web server. With this system, even in situations in which the electric power infrastructure and/or wireless network have been collapsed due to large-scale disaster, smart phone users will be able to share information and movies of an affected area with others via smart phones. In this study, we have checked a range of connectivity of Flying Cloud Server such as wireless LAN distance and concurrent connection user numbers. Then, we confirmed its effectiveness concerning to sharing information in a disaster situation.

Formal Concept Analysis (FCA) Is a data analysis method and it outputs a concept structure called a concept lattice. One of the problems of FCA is that the size of a concept lattice becomes far larger as data become larger. Various methods for reducing a concept lattice have been proposed, but they have disadvantage, e.g. reduced one is not a lattice. In this paper, we propose a method for reduction using attribute inference based on an approximate implication. We also evaluated some methods regarding that a reduced lattice has noise.

A Web-based Java Programming Learning Assistant System (JPLAS) has been developed to help novice students studying Java programming through self-learning. As one function, JPLAS provides the fill-in-blank problem that requests filling in the blank elements in a given code with several blanks. Currently, reserved words, identifiers, or control symbols can be blanked to have unique correct answers, which may be solved without reading the code carefully. In this paper, we propose to additionally blank operators in conditional expressions of core statements in the code so that students can understand the structure to realize the specification. For preliminary evaluations, we generated six operator fill-in-blank problems, and assigned them to students where the number of answer submissions per blank has increased from that of conventional problems.

In this study, we evaluated visual fatigue induced by watching an artificial three-dimensional image with vertical parallax. In the experiment, fifteen subjects completed a task that involved viewing three-dimensional images with four different vertical parallactic angles: 0.0, 0.4,0.6, and 0.8 deg. Visual fatigue was evaluated based on a simulator sickness questionnaire and a critical flicker frequency test. Experimental results showed that the scores of the simulator sickness questionnaire progressively increased with an increase in the vertical parallactic angle, except in Nausea, and the critical flicker frequency decreased the most after watching the three-dimensional image with a vertical parallactic angle of 0.6 deg. These results indicate that a visual fatigue was induced by viewing a stereoscopic image with vertical parallax.

We proposed a low-complexity document classification algorithm to select copy mode. The goal is to select a suitable copy mode during copying process. We first analyzed scanned images and classified them into three modes: text, image, mixed modes. To classify images, we used several features, which include pixel density with low brightness, edge length and text line components. Experimental results showed that the proposed algorithm provided about 95% classification accuracy.
