title: A redicred walking method using haptic sensations on sole
abstract: Recently there are stand-alone VR head-mounted display that can measure the device position and orientation. Therefore, users can enjoy VR contents while walking around. However, it is hard to take a wide real space for walking around freely. To deal with this problem, there is a technique called Redirected Walking (RDW) that makes the user feel like walking bigger space in a narrow space. There are some methods such as using eye tracking and using a virtual revolving door contained in RDW. In this study, I propose an RDW method using shoes with protrusions on the sole. By attaching protrusions to the shoe sole, a friction and sensation felt from the soles of the shoe changes. Hence, it becomes possible to obtain a stronger redirection effect than the method using only visual effects. In this presentation, I show the experimental results of how the redirection effect felt by pedestrians changes when the position, number and angle of the sticks on the back of the shoe are changed. language of the presentation: Japanese 発表題目: 足裏に受ける感覚を利用した歩行リダイレクション手法の提案 発表概要: 近年，デバイス自身の位置と姿勢を計測可能なスタンドアローン型のVR用ヘッドマウントディスプレイが登場しており，ユーザは歩き回りながらVRコンテンツを楽しめるようになってきている．しかし，歩き回るための広い実空間を確保することは必ずしも容易ではない．この問題に対し，狭いスペースでも実際よりも広い空間を移動しているとユーザに錯覚させるRedirected Walking (RDW)という手法が存在する．RDWには視線トラッキングを用いた手法や仮想的な回転扉を用いる手法などがあるが，これらの視覚効果のみによる手法ではリダイレクションの強さに限界があった．そこで本研究では，靴底に突起をつけた靴を利用するRDW手法を提案する．靴底に突起をつけることで靴の滑りや足裏から感じる感覚が変化し，視覚効果のみによる手法に比べてより強いリダイレクション効果を得ることが可能となる．本発表では，靴の裏に貼り付ける棒の位置や数，角度を変えた場合に歩行者が感じるリダイレクション効果がどのように変化したかの実験結果を示す． | |||

title: Pseudo data generation for error correction considering learner's native language
abstract: The goal of this study is to generate high quality pseudo data for learning error correction models. Many English learners' errors are influenced by their native language. For this reason, it is thought that the model learned with the English errors written by the Japanese specializes in correcting the Japanese specific error. There are many previous works on the generation of pseudo error English sentences, but the pseudo errors contain a wide variety of errors. In this presentation, we propose a method using parallel dictionary and multilingual embedding, and mention future research. language of the presentation: Japanese | |||

title: Web Browsing Designed for Immersive VR
abstract: With the spread of HMD for VR, it is assumed that HMD is used on daily basis. In such a situation, there are many problems to browse general web pages using immersive HMD and VR controller, for example, the amount of operation is larger than that in the case of using a mouse and keyboard. It is necessary to consider the display method which has smaller and more efficient way in 3D environment. In this paper, we consider web user interface for immersive VR. Firstly, we focus on the VR devices and create prototypes. language of the presentation: Japanese 発表題目: 没入型VRに最適化したWeb閲覧手法 発表概要: VRに使用されるHMDの普及に伴って、日常的にHMDを使用する状況が想定される。そのような状況で一般的なWebサイトを没入型HMDとVRコントローラを介して閲覧するには、入力においてはマウスなどを用いた場合に比べ操作量が多くなる点や、空中での操作により腕が疲労する点が課題として考えられる。また、表示においては、二次元フラットパネルでの出力を想定されたWebサイトを、三次元空間で効率的かつ疲労が少ない表示手法を考える必要があると考えている。そこで本研究では、HMDに最適なWebUserInterfaceを検討することを目的とする。手法として、まずVRのデバイスに着目しプロトタイピングをおこない評価実験をおこなう。 | |||

title: Development and Evaluation of Multimodal Robotic Touch Care
abstract: Touch care affords positive effects such as mitigation of stress, pain, and dementia. However, from the shortage of physical therapists and care workers as the aging population, patients can not receive enough care. To solve the problem, touch care by a robot has gained popularity. In this study, we develop a hand and motion for the robotic touch care. Furthermore, we propose a multi-modal system that provides not only touch but also visual and hearing stimuli to increase comfortableness and to decrease stress. language of the presentation: Japanese | |||

title: Load-Independent Constant Voltage / Constant Current Design for 2x2 MIMO-IPT abstract: Inductive Power Transfer(IPT) is a technique for transmitting power wirelessly. Recently, this technique has been applied to various electronic devices such as electric vehicles and electric toothbrushes. When the IPT system feeds these electronic equipment targeted for feeding with transmit power, the design of the compensation circuit which can provide constant voltage (constant current) is necessary. Currently, research on IPT from multiple power sources to multiple electronic devices is underway, and previous research proposed a constant voltage circuit for IPT system at the same frequency in two systems where the distance between the power transmission side and the power reception side is known. In this research, we aim to design a constant voltage circuit and a constant current circuit in 2x2 MIMO IPT system when the distance between the power transmission side and the power receiver side is unknown. In this presentation, the design and simulation results of constant current circuits when the distance between the power transmission side and the power reception side is uncertain are shown, and future research policies are also mentioned. language of the presentation: Japanese

title: Automatic HTML generation from a screenshot of the rendered page
abstract: Today, many new web pages are created every day in IT industry. Landing Pages(LPs) are simple web page which aims to make visitor of the web page know about the products or services, and increase the purchase of it. There are increasing demands for publishing new LPs, though it depends on coder's experience and expertise that the process of coding HTML from a rendering image drawn by designers. Beltramelli, 2017. has introduced a method to automatically generate source codes which can be rendered into graphical user interfaces(GUIs) and web pages from a screenshot of the GUI, but their ability is limited within experimental use. This research aims to develop usable application of automatic generator of HTML from the corresponding rendered image. language of the presentation: Japanese | |||

title: On Extraction Method of Representative Evacuation Routes from Evacuees' Trajectories
abstract: When a large-scale disaster occurs, speedy and reliable evacuation is required. In the existing work, an automatic evacuation guiding scheme has been proposed, which provides a speedy and reliable evacuation route with each evacuee and estimates a blocked road segment from the difference between the recommended route and his/her trajectory. However, the estimation of the blocked road segment may become wrong when the evacuee intentionally leaves the recommended route. We expect that such unexpected behavior of evacuees may be detected by analyzing their trajectories. In this talk, as a first step, we propose a method to extract representative evacuation routes from evacuees' trajectories. language of the presentation: Japanese | |||

title: Consensus Algorithm Based on Proof-of-Stake Protocol with Weighted Voting for Blockchain
abstract: The Proof of Stake (PoS) protocol is one of consensus algorithms for Blockchain, in which the integrity of a new block is validated according to voting of nodes called validators. Due to validator-oriented voting, however, voting results are likely to be false when the number of validators who wrongly validate blocks is large. In order to solve this problem, a block validation with weighted voting was proposed. In this approach, the voting profile of a validator is defined as a reliability measure, and a new block is validated by the voting result in which all the profiles of voting validators are taken into consideration. The voting profile of a validator is updated so that the profile value of a validator who correctly validates a new block increases. In this presentation, we introduce the summary of the block validation with weighted voting and profile-updating scheme, showing our future work. language of the presentation: Japanese 発表題目: ブロック・チェーンにおける重み付き投票に基づいた Proof of Stake 型コンセンサスアルゴリズム 発表概要: ブロックチェーンのコンセンサスアルゴリズムの一つであるProof of Stake（PoS）プロトコルでは，バリデータと呼ばれるノードによる投票に基づいて新規ブロックの正当性を検証する．バリデータの投票に基づく検証のため，不正行為を行うバリデータの割合が増加するとブロックの正当性判断が不適切に行われる危険性が増大する．このような脆弱性を解決する手法として，先行研究では重み付け投票によるブロック正当性判断方式が検討されている．具体的には，投票プロファイルと呼ばれるバリデータの信頼度を導入し，バリデータの一票に対して投票プロファイルから算出される重みを考慮することで，新規ブロックの正当性を検証する．バリデータの投票プロファイルは投票結果に応じて更新され，ブロックの正当性を正確に判断するバリデータほどそのプロファイル値が高くなる．本発表では，重み付き投票によるブロック判定法とバリデータのプロファイル更新法について概要を紹介するとともに，今後の研究方針についても言及する． | |||

title: Application of stochastic resonance for biomimetic tactile sensor
abstract: Stochastic resonance is a phenomenon which improves signal-noise ratio in nonlinear system by applying optimal noise. As application of this phenomenon for human, it was reported that white-noise vibration to a fingertip improves the sense of touch and associated motor skills. In this study, we explore an approach of stochastic reasoning for enhancing the touch-to-sense capability of biomimetic tactile sensor. Our preliminary experimental results show that white-noise vibration can enhance accuracy of sandpaper discrimination with stochastic resonance. language of the presentation: Japanese | |||

title:Design of Work Attitude PLR collection infrastructure
abstract:Japanese labor productivity is the lowest in the seven advanced countries(G7) despite the fact that many people are working such long hours with stress as to cause industrial accidents such as mental illness and suicide. Therefore, workstyle reforms that improve productivity while maintaining mental health are urgently needed. In the work style reform, health management based on "Work Attitude" such as stress, work engagement, and workaholism is essential, and it is advisable to measure daily Work Attitude in order to be able to detect the sign of the industrial accident quickly. However, the conventional Work Attitude measurement methods are based on a questionnaire once a year, and then they are not suitable for monitoring. Therefore, in this study, we develop Work Attitude PLR (Personal Life Record) Collection Infrastructure that continuously measures and records Work Attitude that used to be measured only sporadically based on subjective questionnaires, using multimodal information. In this presentation, I will outline the system design of Work Attitude PLR collection infrastructure, and the future research plan. language of the presentation: Japanese 発表題目:Work Attitude PLR収集基盤の設計 発表概要:我が国は，長時間労働やストレスにより多くの精神疾患患者や自殺者が発生しているにも関わらず，労働生産性は先進7カ国(G7)で最下位となっている．そのため，健康を維持したまま生産性を向上させるような働き方改革が急務とされている．働き方改革においては，労働者の好調・不調の程度を示す「Work Attitude」(ストレスやワーク・エンゲージメント，ワーカホリズムなど)に基づく健康管理は必須であり，日常的にWork Attitudeを計測することが求められている．一方で, 従来のWork Attitudeの評価手法は，1年に1回程度のアンケートによるものであり，モニタリングに適したものではない．そこで, 本研究では，主観的アンケートに基づいて散発的にのみ計測されていたWork Attitudeを，マルチモーダル情報を用いて持続的に計測・記録する「Work Attitude PLR（Personal Life Record）収集基盤」を構築する．本発表では,提案するWork Attitude PLR収集基盤の設計および今後の研究実施計画について述べる. | |||
