title: EUI: Enhanced User Interface, intuitive and efficient interface by enhancing user’s virtual hand
abstract: In spite of the exponential increase in computing power in accordance with Moore's law, mouse which is invented over 70 years ago and GUI (Graphical User Interface) which is invented over 40 years ago have been still widely used. GUI realized direct manipulation, but in many cases it is required mode switching or indirect manipulation via UI elements, and has low intuitiveness. Further, in order to manipulate efficiently, it requires users to memorize many keyboard shortcuts, and imposes memory load on users. In terms of interfaces that use multi-touch screen or gesture, which are popular in recent years, keyboard shortcuts can not be used, and in many cases, it is not suitable for tasks that require efficiency. In this research, we propose EUI: Enhanced User Interface, which dynamically assigns functions and presents them with icons to fingers of virtual hands, and verify whether users can use many functions intuitively and efficiently.

発表題目: Enhanced User Interface: バーチャルハンドを拡張することによる、直感的かつ効率的インタフェース
発表概要: 計算機の計算能力はムーアの法則に従い指数関数的に上がっているにも関わらず、インタフェースについては、70年以上も前に発明されたマウスなどのポインティングデバイスや、40年以上も前に発明されたグラフィカル・ユーザ・インタフェース(GUI)が未だに広く利用されている。GUIは、直接操作を実現したが、多くの場合モード切り替えや、UI要素を介して対象を操作する、間接操作を必要とし、直感性が低い。また、効率的操作を行うためには、多くのキーボードショートカットを意図的に記憶する必要があり、ユーザに記憶負荷をかける。近年普及している、マルチタッチスクリーンやジェスチャーを利用したインタフェースでは、キーボードショートカットが利用できないなど、効率を必要とするタスクには不向きな場合が多い。本研究では、バーチャルハンドの指に動的に機能を割り当て、指上のアイコンによってそれを提示するEUI: Enhanced User Interfaceを提案し、ユーザが多くの機能を直感的かつ効率的に利用できるかを検証する。

title: Towards Expressive Virtual Tutors
abstract: Virtual tutors have been developed as animated, embodied conversation agents to simulate actual tutoring sessions. Studies have been focusing on how virtual tutors can be improved through better interactivity and expressiveness. One empirical study recorded non-verbal communication cues of an actual music tutor and used the results to create a virtual tutor. The investigative approach and system architecture of this research can be applied to other academic disciplines. With this, we propose the design, development, and evaluation of virtual tutors teaching history. A sample scenario, some considerations, and current research plan proposal will also be briefly presented.

title: Simulating Scenes of Near-Eye Micro Lens Displays
abstract: Nowadays, we are using various kinds of head -mounted displays as output in virtual reality system. I focus on Near-eye micro lens displays. By using micro lens array, head-mounted displays can be light and compact. Since there are still some limitations, for example it is very difficult to build an ideal demo, we cannot compare results in a convient way. So we choose to use a simulation instead of a real object. In simulation, we can simulate scenes that human beings can see, which is called retina image. Thus we can compare results in different parameters. Later I will describe theory of the simulation.

title: Psychological and Emotional Effects of Performing Actions Towards a Known or Unknown Virtual Doppelganger
abstract: For the past few years, various methods have been developed in order to generate a 3D reconstruction of the human body, enabling us to produce virtual copies of ourselves, also known as virtual doppelgangers. As a result, there is now a growing body of research on the use of virtual doppelgangers in different scenarios, such as for therapy, psychological experiments, and simulations. In this presentation, I will be discussing a paper that utilized virtual reality in order to study user's empathy towards a known or unknown virtual doppelganger expressing pain. From there, I will briefly discuss my research theme, which aims to evaluate the psychological and emotional effects of having users perform actions towards virtual doppelgangers, along with my next steps towards my research goal.

title:3D object arrangement for task guiding application using gravity sensor
abstract: In in-situ AR applications, a 3D content creation phase is important. In order to control 3D contents, users need to control 7 Degree of Freedom(DoF) to determine 3D position, rotation, and scale. However,it is very difficult to annotate a 3D information on 2D Device. In this talk, we will present our extension of our previous work "SlidAR" that allow users to easily control 3D information of position with 2D input device. We like to propose a gravity-aware method for controlling 3D CG annotations for handheld augmented reality application. By using gravity information to help in arrange rotation of 3D content, we can reduce number of input that user have to control during creation phase. By using the proposed method, User can easily control 3D contents

title: Optimization of Wireless Power Transfer with Relay Coil
abstract: Inductive power transfer (IPT) enables electric power to be transferred wirelessly through a pair of magnetically coupled coil resonators. As the capability of IPT technology is limited in transmission distance, a relay coil was introduced by many researchers to increase the transmission distance. However, most of recent investigations discuss the effect of relay coil under resonant condition only and ignore the effect of optimizing relay coil's capacitor. In this work, we investigate the effect of little deviation from resonant condition by changing capacitor on relay coil. Our primitive simulation's results show that the power transmission efficiency can be improved from 4.33% to 34.8% if the capacitor of relay is optimized and the relay coil is put in the middle position between transmitter and receiver. Furthermore, if the position of the relay and the capacitor are jointly optimized, the power transfer efficiency can be enhanced to 92%. Concrete theoretical analysis and extensive simulations are required to firmly verify effectiveness of the proposed optimization scheme.
