In recent years, Bluetooth beacon gets much attention on location-aware services. To obtain an accurate position in a room, we use signal strength of Bluetooth beacons and develop position estimation methods. In our college, we aim to introduce the position estimation system on college. We have installed a number of Bluetooth beacon devices in and around a room and observed RSSI of beacons by portable devices to achieve fundamental knowledge of beacons and estimate their position. In this paper, we take some experiments on different phenomena and with different devices. We confirm that our method can separate completely whether a device is in a room or not. Results show that the average error between device position and estimated position is 2.4m.

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.

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.

This paper investigates AIs that increase their players' amount of exercise by encouraging the usage of various skills in fighting game FightingICE, recently used in a number of game AI competitions. Our research aim is to develop such AIs for promoting players' health with fighting games that use Kinect as the input interface. In our experiment, two types of AIs are used as the opponent against a human player. One of the AIs is based on the k-nearest neighbor algorithm and fuzzy control, and the other is based on UCT, a variation of Monte-Carlo Tree Search. Our results show that the players, participating in the experiment, use more different skills, thus demonstrating higher action entropy, when playing the game against the UCT AI.

The security level of conventional secure protocols is fixed after security environment negotiation. However, communications differ in confidentiality in accordance with their contents. For this reason, a conventional protocol that always keeps the security level constant throughout the whole session is considered to be more secure than necessary. Since transmission efficiency is generally improved by lowering the security level, transmission efficiency is sacrificed when a conventional secure protocol is used. In this study, the secure protocol that dynamically and optimally changes the security level is proposed to solve this problem. Specifically, a variable security level is achieved by using a secret sharing scheme and multiple channels. Furthermore, the proposed protocol is theoretically evaluated.

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.

An infrared camera captures images of objects that emit radiation in the infrared region of the electromagnetic spectrum. In this study, a fluorescence imaging system involving a specifically designed infrared camera was developed. CCDs can detect infrared light in the invisible region of the electromagnetic spectrum (>780 nm); however, a low-pass filter is installed in front of the CCD to filter out most infrared light and prevent the light from affecting the quality of color photos. Although an ordinary camera can take infrared photos when an infrared filter is installed to its lens, a modified camera is impractical because the amount of infrared light entering the CCD is limited, resulting in the requirement of a longer exposure time. Therefore, the principle of modifying a high-speed infrared camera is to remove the low-pass filter and adopt an ordinary shutter speed to take infrared photos.

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.

Stochastic resonance is a phenomenon observed in nonlinear systems for which random noise with optimal level amplifies a weakly periodic signal. In some biological systems, stochastic resonance has been found to be utilized to improve signal transmission. Recently stochastic resonance have been evidenced in photic-driven human electroencephalogram (EEG) and demonstrated to improve performance of brain machine interface (BMI) based on steady state visual evoked potentials. The present study is aimed at giving evidence of stochastic resonance behavior in human auditory steady state response (ASSR) in EEG for developing a high-performance auditory BMI available without visual function. Seven healthy subjects aged 21-24 years old with normal hearing ability participated in the experiment in which their EEG responses to sinusoidally modulated tone with modulation frequency of 40 Hz contaminated by random noise were measured over the entire scalp with varying the carrier frequency (500 and 4,000 Hz), sound pressure of the tone (40-60 dB) and the random noise level (0-50 dB). In four subjects, ASSR amplitude showed a bell-shaped fluctuation with a maximum at noise level of 40 or 50 dB following an increase of noise level, hence the stochastic resonance effect may be elicited in the auditory system. Moreover in the four subjects, we investigated the times when ASSR significantly appeared under two conditions of no noise and the optimal noise that maximized ASSR amplitude. With addition of optimal noise, detection time of ASSR was shortened in three subjects, and ASSR was elicited in other subject. Detection time of ASSR at optimal noise was distributed between three and seven seconds across subjects. These results will be necessary in order to design novel ASSR-based BMIs. Further investigation on the stochastic resonance behavior would provide useful observation for development of auditory BMIs with high classification accuracy by improving the signal to noise ratio in the modulation of ASSR associated with user's intent.

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.
