The application of blockchain technology means that smart home devices will be greatly improved in terms of versatility and security, allowing people to use them more safely and conveniently in their daily home life. For smart home practitioners, blockchain technology means the arrival of the next “window”, indicating that the industry will develop from the budding stage to the popular stage. This paper proposes a smart home system based on the Ethereum blockchain as a platform. Through the use of smart contract technology, it not only builds a closed-loop management platform from energy suppliers to end users but also realizes cross-ecological communication. At the same time, this paper also examined the latency problem of “solidity” in the multi-contract call environment. By comparing the local pace test and the blockchain-side pace test, we found that the function invoked pace inconsistent between local-side and chain-side existed but the delay can be controlled within one second.
Analysis of the Effect of Modality and Social Relationships on Building Common Ground , Yuki Furuya, Koki Saito,Kosuke Ogura ( Keio Univ.),Koh Mitsuda,Ryuichiro Higashinaka (NTT),Kazunori Takashio ( Keio Univ.)
Building common ground with users is essential for dialogue agent systems and robots to interact naturally with people. While a few previous studies have investigated the process of building common ground in human-human dialogue, most of them have been conducted on the basis of text chat. In this study, we constructed a dialogue corpus to investigate the process of building common ground with a particular focus on the modality of dialogue and the social relationship between the participants in the process of building common ground, which are important but have not been investigated in the previous work. The results of our analysis suggest that adding the modality or developing the relationship between workers speeds up the building of common ground. Specifically, regarding the modality, the presence of video rather than only audio may unconsciously facilitate work, and as for the relationship, it is easier to convey information about emotions and turn-taking among friends than in first meetings. These findings and the corpus should prove useful for developing a system to support remote communication.

An implementation of creating human presence of AR navigation system, Ryoma Ariyoshi, Kentaro Taninaka, Kazunori Takashio, IEICE Tech. Rep., vol. 122, no. 193, CNR2022-12, pp. 23-28, September 2022.
In the field of AR, smartphones are often used for navigation, but since the hands are occupied and the immersive experience is compromised, it is preferable to use a stand-alone HMD for AR. However, AR navigation using HMDs is easily affected by the external environment, which inhibits immersion and realism. In addition, the only way to know the traces of a person who was there in the past is to view two-dimensional content, which does not provide a sense of presence or realism. In this research, we aim to implement an AR navigation system that enables interaction with avatars by eliminating factors that impair the sense of presence and realism. As a preliminary step, we investigated how to display avatars with a sense of presence, using HoloLens 2, and experimented with three levels of abstraction, each with motion, superimposed on the Keio University Shonan Fujisawa Campus. The results suggest that the avatar with the lowest level of abstraction and the appearance closest to that of a human being has a greater presence on certain questions. We also observed the “uncanny valley phenomenon,” in which people feel fear and discomfort toward the Avatar when its appearance is closer to reality.
