A trial of navigation system using BLE beacon for sightseeing in traditional area of Nikko

We would like to explain the outline of a trial of navigation system using BLE beacon for sightseeing in traditional area of Nikko. We firstly explain the result of a research of characteristics of visitors to Nikko. From the questionnaire to visitors of Nikko, to support young people (20th) and foreigners by ICT is important. Especially to solve problems of transportation and to provide information of shopping and eating location are important. Also, to give them the culture and history in the approach to the Tosyogu-shrine is important. Then we designed a trial application that works with BLE beacon and performed trial to evaluate the usefulness of navigation system using BLE beacon for sightseeing in Nikko. We found that BLE beacon in outdoor worked well and if visitors are walking, they can find almost all beacons. If they move by bus, BLE beacon also work well.

Information Delivery System for Deaf People at a Larger Disaster

5:46AM, January 17th, 1995, a large earthquake the magnitude of which was 7.3, occurred near Kobe and caused a disaster. Cities near the center of the earthquake were shaken with a seismic intensity 7. 6,434 lives were lost. Depending on this experience, we designed “Information Delivery System for Deaf People at a Larger Disaster (IDDD)” based on mobile phone and ad hoc networking technology with evaluation test performed at many different locations for three years. In this paper, we discussed how our information delivery system for deaf person in disaster (IDDD) has been designed and improved. Especially, brightness and font size were improved and 86% of users agreed that this system was useful. Also, 87% of them answered “Very Useful” or “Useful”. Evaluation result of readability of the display was also favorable, 72% answering “excellent” or “good”.

Navigation system for sightseeing using BLE beacons in a historic area

In this paper, we explained a result of trial in 2014 and 2015 of navigation system using BLE beacon for sightseeing in Nikko. We firstly explain the result of a research of characteristics of visitors to Nikko. From the questionnaire to visitors of Nikko, to support young people (20th) and foreigners by ICT are important. Especially to solve problems of transportation and to provide information of shopping and eating location are important. Also, to give them the culture and history in Nikko area is important. For that purpose, we designed a cognitive model for travel based on Zeigarnik Effect to increase expectation by adding unknown part. Then we designed a trial application that works with BLE beacon and performed trial to evaluate the usefulness of navigation system using BLE beacon for sightseeing and effect of quiz to emphasis expectation of travel in Nikko. We found that BLE beacon in outdoor worked well and if visitors are walking, they can find almost all beacons in 2014. The result of the quiz rally in September 2015 shows that more difficult questions caused higher satisfaction.

Development of the Learning System for Outdoor Study Using Zeigarnik Effect

What is the best way to feel the spirit of the location? In Japan, the students of the elementary school and the secondary school have the school trips for several days with classmates. The purpose of those trips is to visit historical areas in Japan or foreign countries to encourage the students to learn about history, culture and nature in a proactive way. However, it is not easy for them to recognize and understand valuable points such as the artistic points and historical points even if they look at the objects or scenery. To solve this problem, we have developed a new learning model for outdoor studies using mobile phone applying Zeigarnik effect that explains human beings takes much interest in uncompleted or interrupted tasks. In this paper, we explain our study model for outdoor study and evaluate the usefulness of our tool though trials.

Performance evaluation of information delivery system in a major disaster for deaf people based on embedded web system

In this paper, we present an outline of the new Information Delivery System During a Major Disaster for People Who are Deaf (IDDD) designed using a web platform such as node.js and GCM (Google Cloud Message), and explain the performance measurement results. Especially, a new implementation method using web system for embedded system and M2M system is explained. Also, we explained delay to provide disaster information to a user and spreading that information to multiple displays are shorter than previous IDDD.

Evaluation of the New Outdoor Study Scheme Using Mobile Phone Based on the Zeigarnik Effect

Many devices using ICT seem to bring students much information. They look up a lot of information and feel as if they already know the places or things using their PC. However, it is not all of the objects or is much for students to select high quality ones. Some cannot find interesting points among too much information. On the other hands, human beings take an interest in uncompleted or interrupted tasks. Using this human disposition, we create new application for outdoor studying in order to make some remarkable points using the Zeigarnik Effect. A little lack of information becomes a trigger to their interesting study. According to the effective results of our trials, we put it to practical use. In addition, we verified the safety mobile phone’s usage during walking by EEG measurement for practical application.

A Study to Activate Communication by Using SNS on Mobile Phone

Living in the ICT society, not only adults but also children use ICT instruments. However, children usually cannot recognize what happens beyond the screen of ICT devices indeed. It is effective for such children to learn well designed concrete tasks in the classroom step by step. Using our original SNS that designed as closed system in a school, children can share information on the SNS and check classmates’ screen each other without considering danger in the real world. They can know what happened beyond the instruments and many people can look the same massage at the same time. It cultivates ICT literacy and critical thinking skill for children. In this paper, we will explain the result of one of our trials using our learning methods: an essay lesson with SNS.

A Study of Optimization of IDDD (Information Delivery System for Deaf People in a Major Disaster)

In this paper, we describe the optimization of our prototype information delivery system (IDDD) designed for deaf people encountering major disasters for a scheduled trial in 2013, based on problems detected in a preliminary trial experiment. The two major problems that need to be addressed for the optimal design of IDDD are the delay of sending messages from the server, and the flexible maintenance of connections between LED displays, especially in emergency situations. Firstly, we compare performance between two information delivery methods (SMS and GCM) in detail. We conclude that GCM is better than SMS from the viewpoints of delay and stability. Next, we evaluated performance of OLSR from the viewpoint of quick route change, which is necessary to establish connection between devices. We conclude that ad hoc network performance using OLSR is better than implantation of last year using AODV for the purpose of our system. As a result of our analysis, we explain how to enhance IDDD for our planned trial in 2013.

The Site-Specific Learning Model on Mobile Phones Using Zeigarnik Effect

What is the best way to feel the spirit of the location? In Japan, junior high school students go to several day school trip with classmates. This differs from ordinary sightseeing tours, as its purpose is to encourage students to learn about history and nature in a proactive way. After studying about the area in the school, students walk around there by themselves in small groups. Such on-site outdoor activities are very precious, however, they cannot recognize the artistic points and understand that meaning and value if they just look at the objects or scenery. To solve this problem, we have developed a new learning model for outdoor studies using Zeigarnik effects.

Evaluation of an Information Delivery System for Hearing Impairments at a School for Deaf

We have been developing IDDD (Information Delivery System for Deaf People in a Major Disaster) system [7, 8] from 2007. In 2012, we have a chance to develop new IDDD system and test it at the school for the deaf in Miyagi. In this paper, we report the results the system performance test and the users evaluation of the new IDDD based on an experiment at the school for the deaf in Miyagi. As the result, the network performance was increased and application development cost might be half of that of the old IDDD. Also, Fast-Scroll is most legible for hearing impairments people.
