    <p>This paper proposes an indoor localization method for Bluetooth Low Energy (BLE) devices using an end-to-end LSTM neural network. We focus on a large-scale indoor space where there is a tough environment for wireless indoor localization due to signal instability. Our proposed method adopts end-to-end localization, which means input is a time-series of signal strength and output is the estimated location at the latest time in the input. The neural network in our proposed method consists of fully-connected and LSTM layers. We use a custom-made loss function with 3 error components: MSE, the direction of travel, and the leap of the estimated location. Considering the difficulty of data collection in a short preparation term, the data generated by a simple signal simulation is used in the training phase, before training with a small amount of real data. As a result, the estimation accuracy achieves an average of 1.92m, using the data collected in GEXPO exhibition in Miraikan, Tokyo. This paper also evaluates the estimation accuracy assuming the troubles in a real operation.</p>

    <p>In order to encourage elementary school students unfamiliar with Japanese calligraphy to have an assertive attitude towards acquiring basic calligraphy skills, it is imperative to have an application that provides an environment which allows them to practice calligraphy regardless of the time and place. Due to the fact that this application requires an evaluation system that does not need a calligraphy teacher's assistance, this research proposes a method of automatically evaluating a work of calligraphy. All detected strokes within one sheet will be regarded as an object detection problem, therefore, the entire work's evaluation will depend on the detected strokes. Strokes are a fundamental technique in calligraphy, and are a vital component in creating a work of calligraphy.</p>

    近年,様々なセンサを搭載したスマートフォンの発達と普及により,第三者による客観視が困難である「忙しい」や「疲れている」といった人間の内面状態の推定を行う研究が行われている.人間の内面状態を機械に認識させ,内面状態に寄与している因子に関する情報を人々に還元できれば,人間が自身の感情や気分を制御したり,特定の内面状態の獲得や回避といった行動変容へと応用可能である.しかし,人間の内面状態の認識・分析・還元においては,各個人の多様性に適応した動作の実現が課題である.本研究ではスマートフォンのセンサデータを蓄積し,正解データとなる内面状態の注釈をユーザが記録することで,個人の内面状態に寄与している因子を還元するために,因子情報を解析するシステム「MyFactor」を構築した.大学生13名による111日にわたる評価実験を行った結果,被験者全員のデータを用いて学習を行う「統合モデル」と比較して,各ユーザのデータのみを用いて個別に学習した「個人モデル」においては内面状態の推定精度が21%上昇した.また,利用可能なすべてのセンサからのデータを用いて学習した場合よりも,単一センサからのデータのみを用いて学習を行い,最も高精度で分類を行ったモデルを選択した方が高い推定精度を記録し,ユーザに自身の内面状態に関して深い理解を与える可能性を示した.Recently, due to the advance and spread of smartphones equipped with various sensors, human beings&#039; inner states such as &quot;busyness&quot; or &quot;tiredness&quot; can be detected more accurately. If people can recognize the factors contributing to their inner states, they will be able to regulate their own emotions and moods by paying attention to those factors. However, the adaptive system for each individual&#039;s diversity that recognize, analyze, and provide the factors contributing to our inner state is not realized. In this research, we propose a system, MyFactor, that accumulates smartphone sensor data and user annotations about inner states to extract and provide information about the important factors contributing to a user&#039;s inner states. In a 111-day experiment with 13 university students, researchers estimated that an &quot;individual model&quot; developed only with the data of each user had a higher predictive accuracy for human inner states than the generic model developed using data from all subjects. In addition, the model with the highest predictive accuracy, trained by a single sensor, performed better and showed the possibility of giving a deeper understanding of human inner states than the model trained using data from all available sensors.

    Due to the advance in information and communication technologies, smart cities have become an increasingly appealing vision. One indispensable basis in the research, development and implementation of smart cities is urban sensing technologies, which collect various citywide data that will be processed to generate information for understanding the status of cities. Automotive sensing is a novel urban sensing technology that utilizes the mobility of automobiles to conduct sensing tasks. In a collaborative smart-city project with the city office of Fujisawa City, Japan, we designed and implemented an automotive sensing platform called Cruisers, and have deployed it into the garbage collecting trucks of the city to evaluate the applicability of automotive sensing in realistic urban settings. In this paper, we first detail the system design, implementation and deployment of Cruisers and then evaluate its performance in realistic setting.

This research addresses limitations of existing conventional &quot;event-style&quot; tsunami evacuation trainings, that are inflexible in disaster scenarios, training timings, training locations, and participatable trainees. We propose a new ubiquitous computing technology-supported training model named &quot;Asynchronously-Participatable Tsunami Evacuation Training Model&quot; and a prototype system &quot;EverCuate&quot; based on this model. We evaluated the EverCuate system by conducting an extensive user study in Fujisawa city, Kanagawa, with 40 participants and the total number of 229 trainings. The evaluation results validated the effectiveness of EverCuate in terms of easiness in participation to a training, promotion of understanding necessity of different evacuation behaviour for different disaster scenarios, and easiness of analysing people&#039;s real evacuation behaviour from the view point of local authorities.

    Since current digital fabrication relies on 3D printer very much, there are several concerns such as printing cost (i.e., both financial and temporal cost) and sometimes too homogeneous impression with plastic filament. To address and solve the problem, we propose ReFabricator, a computational fabrication tool integrating everyday objects into digital fabrication. ReFabrication is a concept of fabrication, mixing the idea of Reuse and Digital Fabrication, which aims to fabricate new functional shape with ready made products, effectively utilizing its behavior. As a system prototype, we have implemented a design tool which enables users to gather up every day objects and reassemble them to another functional shape with taking advantages of both analog and digital fabrication. In particular, the system calculates the optimized positional relationship among objects, and generates joint objects to bond the objects together in order to achieve a certain shape.

    Recently, many researchers have been focusing on the detection and classification of urban events by information analysis on social networks. Previous works mainly use text analysis of users' posts on social networks for detecting urban events. However, this approach has a limitation that the users' posts must mention the event for the analysis to be conducted. We propose a new method for classifying urban events by extracting user interest from the location-based social network information without text analysis. The proposed method includes analyzing common friends of users in the vicinity of the event venue and extracting common the friends' attributes by referring to related Wikipedia information. We designed and implemented the proposed method, and conducted an experiment for evaluating our method. Our experimental result shows that our method can classify events well in cases where participants have similar interests.

    In Japan, there are 1.2milion kilometers or more of the road, of which 900,000 km of road has been paved. Paved road has been painted compartment line to separate many vehicles and driver-pedestrian. Compartment line is important for drivers and pedestrians because they can recognize for they are aware of the width of the roadway and the sidewalk by the compartment line. Therefore, municipality should inspect the ongoing compartment line but they are inspected by people so the burden for road management is big. The purpose of this research would be to automatically detect the damage of the compartment line. The image obtained from cameras, applying random forest. In this experiment, we used more than about 50,000 of images by capturing a Walking camera and a vehicle-mounted camera. Baseline and precision comparison result, the detection of damage to compartment line, it was confirmed that the proposed method is effective.

In many cases, however, those data are not easily accessible from a computer program due to the lack of APIs to fetch them. In this paper, to cope with this problem, we propose an architecture for discovering, excavating, and streaming the entombed web contents (EWC). This architecture, called Sensorizer, leverages crowd sourcing for accurate EWC discovery, periodic web scraping with a headless browser for excavation from dynamic web pages, and a standardized communication protocol (XMPP) for data streaming to wide variety of applications.

    We present Senbay, a novel smartphone-based platform for capturing and sharing synchronously-recorded video/sensor data stream using animated two-dimensional barcode. In the ubicomp environment, mobile devices have enabled us to capture video and various types of sensor data easily. However, currently we do not have a framework to instantly integrate video and those sensor data on smartphones and share them easily with other users on the net. In this paper, we present Senbay, a platform to integrate video and sensor data stream into single video on smartphones. With Senbay, sensor data stream will be embedded into a video as animated QR code in real-time, thus users can share the \\sensor-federated" video easily on the web, through lots of popular video sharing services. This paper introduces the architecture and evaluation of Senbay and discusses future vision of the sensor-federated video sharing platform along with several applications.

However, it&#039;s difficult that an owner rears aquarium fish interactively based on the state of the fish because fish can&#039;t tell the owner about its state. Thus, this study proposes the &quot;Aqua Mapping&quot; which informs an owner about the condition of an aquarium and fish by indicating fish state on the screen set behind the aquarium using the position information. This system can offer interactive rearing environment between an user and fish through an aquarium.

    Recent progress and spread of smartphones and social network services enables us to transmit text messages with GPS location data anywhere and anytime. Since these location-based SNS messages often refer real-world's events, many researchers have tried to recognize real-world's event through analysis of the messages. In this paper, we define a new index of event classification called popularity, and present a novel method to calculate the index by analysing social network of the events participants. Popularity, which reflects the diversity of event participants, is a useful index of the event for creating various applications such as event navigation or recommendation. We designed and implemented intuitive web-based interactive tool for analysing popularity of events. Through comparative experiments by analysis of proposed system and crowdsourcing, we confirmed that our proposal method provide a certain amount of accuracy for calculating the popularity of events.

    Due to price reduction of the device which can display information such as digital display and projector, public media which provides many kinds of information is emerging. In addition, due to price reduction of sensors and improvement of technique of motion capture, gestural and three-dimentional inputs are emerging to interact with digital media. Interactive public media which supports three-dimentional inputs will increase. However, instructing gestural inputs has difficulties which contains nature of publicness and complexity of the interaction itself. In this research, we propose the method of instructing the way of interaction for users. We implemented the prototype which supports gestural input and applied our proposal on it. We carried out field study with our prototype and we got feedback from 72 participants of the field study. In this paper, we describe the result of the experiment and discussion of our proposal.

    In pervasive computing environments, wireless sensor networks (WSNs) play an important role, collecting reliable and accurate context information so that applications are able to provide services to users on demand. In such environments, sensors should be self-adaptive by taking correct decisions based on sensed data in real-time. However, sensor data is often faulty. Faults are not so exceptional and in most deployments tend to occur frequently. Therefore, the capability of self-healing is important to ensure higher levels of reliability and availability. We design a framework which provides self-healing capabilities, enabling a flexible choice of components for detection, classification, and correction of faults at runtime. Within our framework, a variety of fault detection and classification algorithms can be applied, depending on the characteristics of the sensor data types as well as the topology of the sensor networks. A set of mechanisms for each and every step of the self-healing framework, covering detection, classification, and correction of faults are proposed. To validate the applicability, we illustrate a case study where our solution is implemented as an adaptation engine and integrated seamlessly into the ClouT system. The engine processes data coming from physical sensors deployed in Santander, Spain, providing corrected sensor data to other smart city applications developed in the ClouT project.

    In order to help smart cities to provide responsive services to improve the quality of life of their citizens, a global-scale platform relying on Cloud computing as an enabler to bridge the Internet of Things with Internet of People via Internet of Services, is presented in this paper. This platform will focus on a citizen-centric approach, offering to end-users the possibility of creating their own Cloud services and share them with other citizens, as well as involving other city stakeholders ranging from municipalities to service developers and application integrators. The definition, design and development of the aforementioned platform has been carried out within ClouT project (still ongoing), framed into a joint European-Japanese initiative, where different field trials developed on top of the developed platform, have been deployed in the four cities that take part of the project: Mitaka and Fujisawa in Japan, and Santander and Genova in Europe.

    Roads are becoming deterioration in everywhere. In some places, traffic marks painted on roads are damaged thus needed to be updated. Municipalities must manage road condition and traffic marks (road painting). It is the municipalities task to manage those roads using, for example, special inspection cars and human eyes. However, the management cost is high if a city contains many roads. This paper proposes a mechanism that automates this management. Our idea is to leverage cameras attached to garbage trucks, which run through the entire city almost everyday. The mechanism collects road images and detects damaged traffic marks using an image recognition algorithm. This paper shows the algorithm and reports the benchmark results. The benchmark showed that the mechanism can detect the damaged traffic marks with 76.6% precision.

    According to the spread of smart devices such as smartphones and smart tablets, opportunities to communicate between them will be more increased. Though we usually use WiFi and Bluetooth, it is still burden task for end-users. Many previous techniques to collaborate devices easily has been also proposed, they are not always best solution in some situations. This paper proposes a new interaction method called Vinteracion, which leverages combination of vibrator and accelerometer to send information from smart device to the other smart device. Vinteraction enables users to use touch interaction like Near Field Communication, which provides easy and intuitive way. We present an algorithm and implementation of vibrationbased communication that can be adapted to any combination of smart devices. We also present several applications which leverages Vinteraction effectively. Through an evaluation by using popular six products, we confirmed that Vinteraction is easy to use transfer method with current products with reasonable performance.

Existing researches of human behavior change using life-log data focus on individual human behavior change. But nowadays everyone have communication equipment like smart phones. Group behavior change is very useful to keep workers' health in company and/or managing amount of practice in a sport team. Group has many kind of human relations, for example, manager and normal member. Therefore techniques for individual human behavior change is not effective to groups. The biggest aim of our research is to build the model of group behavior change. Specially, we focus on team behavior change. In this paper, we propose six types of group behavior model based on the "competition" and "collaboration" technique. We used encouraging team modification application in sports team and laboratory for keeping the sit-up exercise for 3 weeks. Sit-up exercise is very important to preventing the injury and keep fit for the sport team and the laboratory member. We create 8 groups in a team. We evaluate and consider this model based on the change of the self-efficacy and number of sit-up activities.

    The Smart City concept relates to improve efficiency of city services and facilitate a more sustainable development of cities, as well as standing as the key concept for the future technological developments in Future Internet, IoT and, for the great quantity of information stored, big data and cloud computing. In this sense, this paper presents the ClouT project, a joint European-Japanese project, whose main aim is making citizens aware of city resources and helping them to use and care these resources by mean of smart IoT services in the Cloud. This objective is addressed through the definition of a three layer architecture composed of: CIaaS, CPaaS and CSaaS layers. On top of this architecture, different use cases associated to different application domains will be developed, mainly within the four cities that take part of the consortium: Mitaka and Fujisawa in Japan, and Santander and Genova in Europe.

    We propose a novel technique that aggregates multiple sensor streams generated by totally different types of sensors into a visually enhanced video stream. This paper shows major features of SENSeTREAM and demonstrates enhancement of user experience in an online live music event. Since SENSeTREAM is a video stream with sensor values encoded in a two-dimensional graphical code, it can transmit multiple sensor data streams while maintaining their synchronization. A SENSeTREAM can be transmitted via existing live streaming services, and can be saved into existing video archive services. We have implemented a prototype SENSe- TREAM generator and deployed it to an online live music event. Through the pilot study, we confirmed that SENSe- TREAM works with popular streaming services, and provide a new media experience for live performances. We also indicate future direction for establishing visual stream aggregation and its applications.

Smart city services should support in both usual and emergency situations, however, the system requirements to the different situation differs because network availability and sensing/acting priority are different among the situations. To fulfil various requirements for smart city serves, we present vertical/horizontal service orchestration through Fujisawa field trials in Japan.

    This paper proposes a concept of linked participatory sensing, called LiPS, that divide a complex sensing task into small tasks and link each other to optimize social resource allocation. Recently participatory sensing have been spreading, but its sensing tasks are still very simple and easy for participants to deal with (e.g. Please input the number of people standing in a queue. etc.). To adapt to high-level tasks which require specific skills such as those in engineering, the medical profession or authority such as the organizer of the event, we need to optimize social resource allocation because the number of such professionals are limited. To achieve the complex sensing tasks efficiently, LiPS enables to divide a complex sensing task into small tasks and link each other by assigning proper sensors. LiPS can treat physical sensors and human as hybrid multi-level sensors, and task provider can arrange social resource allocation for the goal of each divided sensing task. In this paper, we describe the design and development of the LiPS system. We also implemented an in-lab experiment as the first prototype of hybrid sensing system and discussed the model of further system through users' feedback. Copyright 2014 ACM.

    Designing novel and meaningful interactions in the domain of Augmented Reality (AR) requires an efficient and appropriate methodology. A user centered design process requires the construction and evaluation of several prototypes with increasing technical fidelity. Although the main content of the application can already be conveyed with prerendered video, one of the main interactions in AR - The user-selected viewpoint - is only available in a very late stage. We propose the use of panoramic 360? video for scenario based user evaluation, where the user can select his point of view during playback. Initial users report a high degree of immersion in the constructed scenario, even for handheld AR.

    In recent years, the steady emergence of digital communication, especially social media, has increased the 'placelessness' of inter-person communication practices, i.e., lessening the need to reside co-located in order to communicate. When these communication practices carry over to co-located settings, they introduce redundancy and potentially even harm the co-located context, since use of personal technologies tends to isolate users from their surroundings. In this position paper, we want to raise awareness on how interactive public displays could alleviate this redundancy and potential isolation. We present a model of reinforcing co-located communications, and illustrate it through example use cases. Copyright © 2013 ACM.

    Recent progress in information technology enables people to easily broadcast events live on the Internet. Although the advantage of the Internet is live communication between a performer and listeners, the current mode of communication is writing comments using Twitter or Facebook, or some similar messaging network. In one type of live broadcast, musical performances, it is difficult for a musician, when playing an instrument, to communicate with listeners by writing comments. We propose a new communication mode between performers who play musical instruments, and their listeners by enabling listeners to control the performer's camera or illumination remotely. The results of four weeks of experiment confirm the emergence of nonverbal communication between a performer and listeners, and among listeners, which increases camaraderie amongst listeners and performers. Additionally, the dramatic impact of a performance is increased by enabling listeners to control various camera actions such as zoom-in or pan in real time. The results also provide implications for design of future interactive live broadcasting services. Copyright 2012 ACM.

    Some baseball players have their shoulder and elbow injuries cause of the disorder of the throwing form and an overwork. Fielders especially practice without knowledge of their bodies and care for it. However it is difficult to recognize their throwing form and number of throws. This research has been supported player's performance by analysis of player's throwing using sanjigen-motion-capcher and douga-bunnseki for all time. But this research has problems with place and time. Because it doesn't assume actual practices. So we are researching for their new supports to improve their form and to take a break by using the radio small acceleration sensor which you can check your throwing form and number of throws easily.

    Ubiquitous computing and communication are the key technology for achieving economic growth, sustainable development, safe and secure community towards a ubiquitous network society. Although the technology alone cannot solve the emerging problems, it is important to deploy services everywhere and reach real people with sensor enabled smart phones or devices. Using these devices and wireless sensor networks, we have been creating various types of ubiquitous services which support our everyday life. In this paper, we describe ubiquitous services based on a HOT-SPA model and discuss challenges in creating new ubiquitous services with smart enablers such as smart phones, wireless sensor nodes, social media, and cloud services. We first classify various types of ubiquitous service and introduce the HOT-SPA model which is aimed at modeling ubiquitous services. Several ubiquitous services, such as DIY smart object services, Twitthings, Airy Notes, and Sensing Cloud, are described. We then address the challenges in creating advanced ubiquitous services by enhancing coupling between a cyber and a physical space.

    There has been a great effort to create context-aware technology to support user&#039;s life. Context-aware technology is useful because it resolves user&#039;s demand in prior. However, if it fails to recognize context correctly and controls appliances incorrectly, users may feel uncomfortable about the environment. Context recognition error is currently unavoidable, therefore, notifying the user of what kind of result each context has, is considered to be important in order to ease user&#039;s discomfort. In the similar way, it is important to show the smartness of ubiquitous computing environment to people who don&#039;t know about the environment. To effectively provide this information to the users, we propose an interface called Second-sighted Glasses, inspired by the movie titled &quot;Next&quot;. The glasses shows users the future effects of each action they may take with augmented reality technique.

    The paper proposes an intuitive device selecting interface called "Vib-connect" for device collaboration. Recent progress in Information Technology allowed various devices to join wireless network. As a result, various ways of device collaborations and services became possible. However, interfaces for selecting devices are still complicated for end-users and far from being intuitive. To solve this problem, we propose "vib-connect", an interface which enables users to select device intuitively by pasting a vib-connector, a small vibration-based device. Vib-connect solves these problem by implementing these device information as a unique vibration pattern. By keeping smartphones or any kind of vibration generating device, end-users can easily select devices to collaborate. We implement a prototype, and through the evaluation, we confirmed high accuracy in vibration pattern detection and high usability satisfaction by nonexpert users. By using "Vib-connect", users without any technical expertize can easily select devices to collaborate with.

    We propose a simple interaction to transfer information on smart phone to laptop/tablet PCs. We often encounter the situation that we need to send URL, which is preliminary accessed in mobile devices, from mobile devices to personal computers (PCs) to see the web page with wider screen. To support this information transfer, we utilize combination between vibrator in smart phones and accelerometer in laptop/tablet PCs. URL information is encoded to vibration patterns, and the patterns are detected and decoded by accelerometer in PCs. We demonstrate the interaction's efficiency and reasonability with actual products. © 2011 Authors.

    This paper proposes a low energy consumption time estimation scheme for wireless sensor networks (WSNs) called LECTES. In WSN applications, drift of wireless sensor nodes' clocks is one of the most critical issues when processing data. Many researchers have been challenging this problem by proposing time synchronization protocols, such as FTSP, TPSN and RBS. LECTES does not synchronize sensor nodes' clocks, instead, it estimates the sensing time by subtracting the time taken to process data from the reception time of packets. We implemented LECTES on MAC layer of Iris mote, and confirmed that it achieves the average accuracy of 0.488μs as opposed to 1.618μs with FTSP in single hop. The evaluation results further proved that in comparison to FTSP, LECTES 1)increased sensor nodes' lifetimes by 19.8%, 2)decreased the growth of error per hop from 0.694μs to 0.256μs in a 9 hop network, and 3)decreased the compiled program size by 8,046 bytes of ROM and 452 bytes of RAM.

    The advancement of information technology provides customers various ways to purchase products, and large number of customers are buying products online rather than buying them at brick-and-motor stores. In spite of that, customers are stimulated to purchase products at brick-and-motor stores through the use of QR code and digital cash. It is said that customers will be more encouraged to buy products at brick-and-motor stores by adapting new technologies, such as RFID and electronic device. In consequence, firing clerks and less jobs being required are resulting in less communication between customers and clerks. Communication between customers and clerks increases the chance of customers purchasing products, and enables customers to the choose most desired products. Thus, in order to improve the convenience of brick-and-motor stores, it is important to encourage clerks to have communication with customers. Although, there is a proper timing to wait on a customer, and there is a great chance of making customers feel uncomfortable as a result of wrong timing or way of service. In order to solve this problem, we aim to assist customers and brick-and-motor stores by detecting customers' "indecision" when purchasing products.

    This paper proposes event description language using temporal relation for creating various services with smart objects. By attaching sensor nodes to everyday objects, users can augment the objects digitally and take the objects into various services. When creating such smart object services, users should define event using physical value from sensors. The most common event is defined by simply describing threshold of sensor value and logical operation. Therefore, when end-users want to define more complex event, they need to use hard programming language such as C or Java. For defining such complex event easily without complex programming language, we propose a new event description language based on temporal relation between simple events.

    Many context analyses have been done in recent years with the high-end sensor equipment. Also, some research work on extracting "atmosphere", which is the feeling that an event or place gives you. However, every atmosphere produced is depended on one's feeling or the mood that they are in, and it is difficult to analyze it in a public space with an existing research. In this research, we try to demonstrate these atmospheres visible with the "momo!" system, by using vital sensors to analyze the mood. The research goal is to apply various services with the technology of atmosphere extraction.

    This paper proposes the concept of DIY (do-it-yourself) ubiquitous computing, an architecture allowing non-experts to establish ubiquitous computing environments in the real world. This concept has been implemented in the "u-Texture", which is a self-organizable panel that works as a building block. While the traditional scheme attaches devices such as computers, sensors, and network equipments externally to make everyday objects smart, the u-Texture has these devices built in beforehand to assemble smart objects. The u-Texture can change its own behavior autonomously through recognition of its location, its angle of inclination, and surrounding environment by assembling these factors physically. This paper describes the design, the implementation, and various applications of u-Textures to confirm that the concept can contribute to establishment of ubiquitous computing environments in the real world without expert users.
