Slides have become an integral part of today’s educational activities, and the use of proper images in teaching slides can improve students’ comprehension and satisfaction. Finding proper images, however, can be a costly task for the authors of teaching slides. We present a study that explores the uses of Generative Adversarial Nets to generate appropriate images automatically, thereby reducing the costs to find proper images for different teaching materials.

Abstract. The Kashiwa Library (KL), The University of Tokyo, holds a collection of old paper maps over the world, about a half of which were originally collected for the International Map Exhibition 1980 in Tokyo. The collection has 3,200 maps published in the 1970s and 1980s, and 1,260 of them were displayed at the exhibition. The map collection is important because it represents the cartography at the emerging era of new technologies and techniques such as satellite remote sensing, computers and GIS for map production (Arikawa et al., 2016). These maps were donated from the Japan Cartographers Association in March 2016, after their collection and storage by the association since the exhibition. In the Japanese fiscal year 2017, the Center for Spatial Information Science (CSIS), The University of Tokyo, and KL started a cooperative research project to produce a digital archive of this map collection, with support from the University of Tokyo Academic Archives Project that facilitates digital archiving of academic materials owned by various units at the university. This presentation explains the procedure of making our digital archive “Kashiwanoha Paper Maps Digital Archive”. “Kashiwanoha” is the address of the Kashiwa Campus of The University of Tokyo where KL and CSIS are located, and it literally means “oak leaf”.

Abstract. Transit Oriented Development is the approach of urban development which maximizes the land use of residential, business and leisure around the public transit stops. A good TOD system can not only alleviate the contradiction between traffic congestion and insufficient land use for urban development but also significantly improve the convenience of urban residents' work and life. Moreover, while limiting the disorderly spread of the city, a good TOD system can solve the environmental and traffic problems caused by automobiles and promote synergy and integration between the industries. Traditionally, TOD is designed for facilitating the pedestrians to a convenient access to the public transportation systems so as to increase the usage rate of public transports. Despite pedestrians as the target, there are a lot of passengers move to the station via other means such as bus and bicycle. In the previous research, these two kinds of mobility are not included in the evaluation of TOD system as they have a lot of limitation on interacting with the facilities around railway station. In recent years, sharing bicycle becomes popular for solving the problem of the last one kilometer. Comparing to other means of mobility, sharing bicycle is more flexible than bus and has a higher usage rate than private bicycles. In addition, the sharing bike users have a wider access area than the pedestrians. Thus, sharing bicycle is able to play an important role in TOD system. In Tokyo metropolis, there are over 1000 railway stations and more than 50% of residents commute by railway. Nevertheless, the bike sharing system is available only in some specific area, which indicates a lot of room for the development of bike sharing service. In this research, we follow the previous studies of walkability measurement and apply two indicators include road network connectivity and facility accessibility for illustrating how could bike sharing outperforms walking in a TOD system with the case study of Tokyo 23 wards. The result of this research can instruct the government on improving the current TOD system as well as help build a sustainable society.

教育者が新規の知識を教授するとき、学習者がいつどこで「つまずき」を感じたかを把握することは非常に重要である。しかし、学習後の主観評価や小テストだけで学習者の「つまずき」を詳細に推定するのは困難である。学習中のリアルタイムな応答や精神状態変化を計測できれば、適切な教授方法の開発に有用であると考えられる。本研究では、学習中の精神状態を反映する信号として、脳波および視線運動に着目し、学習者の脳波・視線の同時計測および信号解析を実現するシステムを開発した。本稿では、本システムにより取得した自学学習中の脳波・視線応答の結果例を紹介するとともに、生理応答計測の教授方法改善可能性について議論する。

Recently, many kinds of location-aware applications of smartphone are developed. However, it is difficult to test them for usability in the same way as the non-location-aware ones because of the test environment. For example, in case of supportive applications for emergency situations, the usability test can be carried out only in normal period of outdoor fields. Key competitive technologies beyond the issues will be Augment Reality and Virtual Reality. We focus on advantages of laboratory experiment and present a usability test environment of location-aware apps based on virtual real world using Google Street View. In this paper, we aim at understanding the weaknesses and strengths of this approach. We developed an initial prototype of the usability test environment and a simple map viewer app. The usability test has two conditions from a designated start point: (c1) go to a designated place and (c2) explore the area freely. We observed two participants' behaviors: (b1) movement in the virtual real world, (b2) body motion, and (b3) operation of the map viewer app. From the results, we discuss the better ways to collect these data as well as the weakness and strengths of laboratory-based usability test environment. These outcomes spotlight laboratory survey's strengths of fine grain spatiotemporal data.

Nowadays, there is an explosion of spatio-temporal data, such as big data of human movements and aerial photographs taken in time series. Interactive and dynamic visualization of such data play important roles in researching and applications in the fields of traffic controlling, education, storytelling and so on. On the other hand, besides of the "modern" digital data, there are also large amount of "traditional" analogue data in the forms of maps, books, photographs and so on. Such analogue materials are valuable for historical researches and education, but current spatio-temporal visualization systems are not good at dealing such analogue materials compared to their performances on digital data. This paper introduces our research on collaging analogue maps and timeline graphs through geo-references and time-references, to enrich the analogue materials with multimedia digital data, and enable user interactions and dynamic visualization of the enriched data on digital devices for researching, education and storytelling.

User-generated storytelling based on analog maps with local and dynamic georeferencing

Min Lu, Ruochen Si, Masatoshi Arikawa, Hideki Kaji

Maps are important vehicles for storytelling. Although the ubiquity of current web mapping services has brought great conveniences to creating map-based content, they also bring restrictions in map representation. Conventional analog maps are still being created and widely used. Some of the well-designed ones are highly contextual, and are more suitable for storytelling with related backgrounds. To utilize analog maps in location-aware mobile environments for storytelling, local and dynamic georeferencing is introduced to attach geospatial information to the analog map images without stretching them and destroying the artistic designs. A data format extended from a popular GIS data standard is designed, for creating and sharing storytelling content easily by attach multimedia resources to georeferenced map images. In cooperation with local communities, prototype developments realized tools for map-based storytelling content creation and smartphone applications for browsing the content in walking tours.

Classes for creating location-based audio tour content: A case of user-generated LBS education to university students

Min Lu, Masatoshi Arikawa, Atsuyuki Okabe

Lecture Notes in Geoinformation and Cartography ( Kluwer Academic Publishers ) 375 - 398 2017年01月

A course named Seminar of Culture Studies is given to undergraduate students in the School of Cultural and Creative Studies of Aoyama Gakuin University in Tokyo, Japan, in which a new mobile application named Manpo was applied for the students to create location-based audio tour content in 2013, 2014 and 2015. With little background knowledge on geography and cartography, the students tried to draw maps and create georeferences for positioning on the maps using Manpo’s functions. They also focused on recording audio guides for the POIs and walking routes, and bundled them to the maps together with photos and texts. The procedures of the classes and the students’ performances were observed, in which the problems encountered by the students showed the difficulties, such as achieving appropriate georeferencing for accurate positioning, for non-professional users. However, the classes and students provided hints to the further development of Manpo, which also improved the classes and the students’ works. As the course was proved to be a success, it inspired future research plans of a platform that can involve researchers, developers, mapmakers, local communities, and ordinary users to provide user-generated content including diverse maps for more attractive location-based services.
