근 미래 스마트 홈 사용자의 공간별 사용 패턴과 스마트 허브 시나리오 제안

Abstract

Background: Data generated when using multiple electronic products in a smart home environment is controlled by a smart hub that collects the data and transmits it to the cloud. The current smart home user is a speaker-type smart hub with artificial intelligence, which allows the home device to be controlled with Voice User Interface. With VUI, an artificial intelligence can identify the user's product usage pattern and build a linkage between various products that can satisfy the user's purpose in a smart home environment. The purpose of this study is to figure out the product usage pattern collecting method of the near future smart home users and to propose the near future smart hub. Methods: The researcher placed 59 product cards on living room, bedroom, kitchen, bathroom, and front door space of living environment blue print. The role-play of each space of the near future smart home was performed using the card arranged by the participant. Participants were provided with seven contexts of waking up (07:30), leaving the house (09:00), returning to the house (19:30), communication (22:00), work out (21:30), shopping (22:30), and bedtime (23:30) in 2025. Before the role-play, the participants were asked to identify a smart hub suitable for the role-play of each space and context, and the researcher conducted a role of artificial intelligence of that smart hub, A participant and researcher exchanged one-on-one speech. Result: In the living room, bedroom, and kitchen space, the usage pattern data of four role-playing participants were collected; the result of the front door where three participants did not place cards were excluded. The utterance generated in role-playing were textualized, and the products mentioned were extracted according to the order of usage of the product appearing in the speech and converted into the user's product use pattern data. The number of times that participants identified a certain product as smart hub in role-play in each space also became the evidence data to support the future smart hub scenarios proposal. Conclusion: The data of 112 product usage patterns according to the time context and space of the near future smart home were collected. Based on the process of voice interactive system, a researcher has approached for the method of finding product usage patterns and has derived the near future smart hub and smart hub scenario through the process of analyzing the collected data.
