Virtual IoT: An IoT Platform with MR Technologies Realizing Low-cost and Flexible Notification of Life-support Information
Abstract : The miniaturization and decreasing cost of networking computers, along with the advancement of cloud infrastructure has eased the implementation of IoT products for manufacturers. The increase in such products has led to the rise in IoT devices with information provision function. However, it is difficult to make products display information in consideration of the design on the surface, like daily commodities, since it requires the device to have a wealth of computational resource. In this paper, we propose Virtual IoT System, the approach which adds information-giving functions to the non-computing objects using Mixed Reality technology. This system enables appropriate things to give adequate information at the appropriate timing. In this paper, we explain the detail and design of Virtual IoT System. In addition, we conduct an experiment to evaluate the usability and expressive power of Virtual IoT system.

With the evolution of computer gaming hardware causing entertainment to change, on-screen PvP video games still remain to be the most popular option. Most of these games have a game mode versus CP(Computer Player). However the experience in such modes can lack satisfaction on the player side due to the lack of engagement, challenge, and involvement. This research will design and evaluate an auxiliary system that enhances the experience of playing against CP by using an on-screen virtual agent. Emotion will be synthesized through an emotion engine using the game state as an input, and the agent will display facial expressions and appropriate utterances.

テレプレゼンスロボットなどに搭載されているビデオチャットでは，遠隔で会話に参加している相手の背景が見えてしまうことによって，相手が別の空間にいるということが意識されてしまう．そこで我々は，ビデオチャットにおける相手の映像の背景部分のみをテレプレゼンスロボットが置かれている場の背景映像に入れ替えることで，遠隔参加者との一体感が高まりコミュニケーションがより活発になる，という仮説を立て研究を行なっている．本研究ではシステムのプロトタイプの実装および評価実験を行い，背景をロボットが置かれている場の画像に置き換えることで会話の活発度や遠隔者の存在感の向上に寄与することが明らかになった．

In recent years, 3DCG characters have become widespread and are being used in-screen agents as avatarsfor interactive agents. In this study, we propose a method to give a sense of coexistence and unity of space by lettingthe user follow the background and the method of projecting the gaze target to the pupil. For the experiment, anagent that can manually select the gaze target was created and evaluated.

In a robot and human conversation, the robot’s flat voice is a one of the factor that boring conversation. Automatically adjust emotional expressions to speech from virtual emotion in a robot. In this study, I verify that communication will be smooth when it considers the flow of emotional change from the conversation history.

The miniaturization and decreasing cost of networking computers, alongwith the advancement of cloud infrastructure has eased the implementation of it inproducts for manufacturers. The increase in such products has led to the rise in IoTdevices with information-provision function. However, it is difficult to give suchfunction to products which engage in an one-way association in our daily life likedaily commodities, since it requires the device to have a wealth of computationalresource. In this paper, we propose Virtual IoT system, the approach which addinformation-giving functions to the non-computing objects using Mixed Realitytechnology. This system enables appropriate things to give adequate informationat the right timing. In this paper, we explain the detail and design of Virtual IoTsystem. In addition, we conduct an experiment to evaluate impression and usabilityof Virtual IoT to disclose the descriptive power.
