title: Development of document synchronization software abstract: In the development of software libraries, at the same time the document also update the library update, helps to properly present the use of the library to the library user.There is a case in which the document is not updated to the latest one for a variety of reasons. In this study in order to solve the problem, I have developed a software that has the following functions, to assist in the document update of library developers and if documents have not been updated, indicate that not updated to the library user. language of the presentation: Japanese | ||

title:An analysis method to understand the impact of test code change in OSS development
abstract:Software developers often need to change a source code to fix a bug or enhance. At the same time, developers might need to update a test code to make sure that the source code is working properly.However, developers are not often update test code for a long time, and then developers might overlook an issue. On the other hand, if developers often update the test code, they might likely to introduce a new bug. In this study, I would like to introduce my study "The impact of a risk caused by a test code change in OSS development". 発表題目:OSS開発におけるテストコード変更とソースコード品質の関係分析手法 発表概要:ソフトウェア開発者は欠陥修正，機能拡張のためのソースコード変更と同時に,テストコードの更新をすることが，ソースコードの動作を保証するために極めて重要である．しかし,開発者はテストコードを変更していないことが多く，テストコードが機能していないことが多い．本発表では,OSS開発においてテストコード変更とソースコード品質の関係を分析するための手法確立に向けた方針について報告する. | ||

title: A Research on Optimal Parameters of Viterbi Decoder for IoT Applications***
abstract: This research is our first step on the purpose of developing low-complex Viterbi decoder for IoT applications. We evaluate how the values of Viterbi decoder’s parameters such as trace back length (L), input data bit-width (D), and LLR truncated value (E), affects to BER and PER of a communication system. The IEEE 802.11a simulator is used because it is considered to be suitable for IoT applications. Our simulation results show that both BER and PER performance are improved if L value increased. However, if L is large enough, i.e., L 60, the performance improvement becomes insignificant. In addition, both BER and PER performance are continuously improved if D value increases from 1 to 5 bits. The best improvement of both BER performance (i.e., 1.8dB) and PER performance (i.e., 1.5dB) can be seen when D increases from 2 to 3 bits. Thus D = 3 is proposed for Viterbi decoder’s hardware development. Finally, our research shows that truncating the LLR value to E = 1:75 helps the Viterbi decoder achieves the best BER and PER performance in case D = 3 bits. Base on these research results, we come to the conclude of using 20 ＜＝ L ＜＝ 40, D = 3 bits, and E 1:75 for future development of low complex Viterbi decoder circuit for IoT applications. Furthermore, in this paper we introduce some mathematics equations for simplifying the Viterbi decoder process. language of the presentation: Japanese | ||

title: The relationship between social sentiment and stock price index
abstract: In the previous study that analyzed internet stock forum, it is implied that we can estimate the stock return and volatility with the post on stock forum. In this study, we focus on VIX, that is a stock price index which is related to investor’s uneasiness. We make a hypothesis that VIX has strong relationship with investor’s sentiment. We analyze the posts with natural language processing and machine learning. And investigate the relationship between social sentiment and VIX. language of the presentation: Japanese 発表題目: ソーシャルセンティメントと株式指標に関する研究 インターネット株式掲示板と株式市場を分析した先行研究では、掲示板投稿がボラティリティおよび出来高を予測できる可能性を示唆している。本研究では、“恐怖指数”と呼ばれ株式指標の中でも投資家の不安心理と結びついた指標である”Vi指数”に着目し、掲示板投稿から得られる投資家の感情と関連の高い株式指標であるという仮説を立てる。掲示板投稿を自然言語処理および機械学習によって分析を行い、Vi指数との関連性を明らかにする。 | ||

title:Effect of electronized paper tourist maps on tourist feeling
The purpose of this study is to confirm the effect on tourists when they use a tourist maps with added their location information. Most electronic maps are general purpose maps, but a general purpose map is unfit for tourism. This study shows the difference in usefulness between a tourist map that shows the users location, and a general purpose map that shows the users location. We asked tourists to compare Google Maps and scanned tourist maps that show the user's location information, testers praised the proposed map more than the general purpose map in tourism. Based on our results, we expect this work will be used for the development of new maps in tourism. language of the presentation: Japanese | ||

title: Near-Eye Light Field Displays
abstract:Recently, head-mounted displays (HMDs) are attracting attention and popularity. Then I focused on the Near-Eye Light Field Displays as immersive HMDs, which are developed by NVIDIA. They include microlens arrays, which have some good features. Near-Eye Light Field Displays have some advantages and limitations compared to the conventional HMDs. The benefits of using microlens arrays is to make HMDs thinner and comfortable for users. In this presentation, I will explain the principle of magnifier array to make a virtual image that is generated by microlens array. Then I will describe benefits and limitation of using microlens array. language of the presentation: Japanese | ||

title: Head gesture recognition with a wearable camera
abstract: The idea to use first-person point-of-view videos captured by a wearable camera for understanding the person's vision and behavior is called First-Person Vision. We aim to recognize others' behaviors with a head-mounted camera instead of blind people. At the first step, this study focuses on recognizing head gestures of someone who is talking with in natural conversation. To train a classifier, conversation videos were recorded by a static camera and a wearable camera, and annotated. We are making a classifier using this dataset. language of the presentation: Japanese 発表題目: ウェアラブルカメラを用いた頭部動作認識 発表概要: ウェアラブルカメラによる一人称視点映像を用いた研究分野はFirst-Person Visionと呼ばれ、人の視覚や行動を理解するための手段として注目され始めている。 本研究ではこれを視覚障碍者などのコミュニケーション支援に役立てることを目的に、頭部に装着したカメラによる相手の振る舞いの認識を目指す。 その足がかりとして、一対一の自然会話における話し相手の頭部動作を対象とする。 動作識別器の訓練のために、被験者を募って固定カメラ・ウェアラブルカメラから会話映像を撮影し、アノテーションを行った。 今後、この得られたサンプルを用いて動作識別器を構築する。 | ||

title: Enjoyment intention to use and actual use of a conversational robot by elderly people abstract: In this paper we explore the concept of enjoyment as a possible factor influencing acceptance of robotic technology by elderly people. We describe an experiment with a conversational robot and elderly users (n=30) that incorporates both a test session and a long term user observation. The experiment did confirm the hypothesis that perceived enjoyment has an effect on the intention to use a robotic system. Furthermore, findings show that the general assumption in technology acceptance models that intention to use predicts actual use is also applicable to this specific technology used by elderly people. language of the presentation: Japanese | ||
