스마트 홈은 유비쿼터스 환경의 각종 센서와 정보 가전에서 얻어지는 데이터에서 사용자의 Context를 추출하여 사용자에게 적응적인 서비스를 제공한다. 본 논문에서는 유비쿼터스 컴퓨팅 환경의 스마트 홈에서 거주자 중심의 정태적, 통태적 컨텍스트 정보를 표현하기 위한 요구사항을 분석하고 이러한 요구 사항을 만족하기 위한 트리플 구조 기반의 컨텍스트 모델을 제안한다. 제안한 스마트 홈을 위한 컨텍스트 모델은 표현력이 강력하고, 확정이 쉽고, 재사용이 가능하며 개인화된 서비스를 위한 추론에 용이한 정보 구조를 제공한다.

스마트 홈은 홈 내의 여러 장치와 서비스가 서로 협력함으로써 최적의 가정환경을 만들고, 거주자가 원격지에서 홈 내의 특정 가전을 제어할 수 있도록 발전하였다. 현재 가장 많이 사용되어지고 있는 웹 서버를 이용하는 방법은 고정 IP(Internet Protocol)를 가지고 있지 않고, 푸쉬(Push) 기능의 부재로 인해 거주자가 지시한 내용이 잘 진행되어지고 있는지 알기 위해 새로운 플랫폼을 구축하거나, 다시 접속을 하여야만 진행상황을 알 수 있다. 또한, 제어를 원하는 정보가전의 상태를 먼저 받아야만 제어가 가능하기 때문에 실내에서는 그 상태를 사용자가 알고 있지만, 패킷의 오류 발생은 제어의 지연 원인이 된다. 유비쿼터스는 인간친화적인 형태의 제어 장비를 제안하여 오고 있다. 본 논문에서는 메신저와 자연어 처리의 구문 분석을 활용하여 정보 가전을 제어할 수 있는 방법을 제안한다.

Recently, the concept of PES(Personal Environment Service) is being widely discussed on various standardization organizations such as ITU-R, ETSI, 3GPP, TTA and etc. The purpose of PES is to introduce the services which can dynamically, automatically and intelligently reconfigures the electronic, electrical, and mechanical equipment surrounding the user according to the user preferences included in a user's profile by using a smartphone embedding WPAN radio technologies such as bluetooth and WiFi. This research introduces an Android Platform-based PES system which consists of a PES app, PES devices and a PES server. A smartphone platform is Android 2.2(Froyo) version and 4 simulated PES devices were implemented by using Galaxy Tab. It has shown that the PES would be a killer application of M2M(Machine-to-Machine) or D2D(Device-to-Device) in the future and it would need to study how to update a user's profile based on analyzing user's behaviour for enhancing the PES user's satisfaction.

The smart home is a technology that can monitor and control by connecting everything to a communication network in various fields such as home appliances, energy consumers, and security devices. The Smart home is developing not only automatic control but also learning situation and user's taste and providing the result accordingly. This paper proposes a model that can provide a comfortable indoor environment control service for the user's characteristics by detecting the user's behavior as well as the automatic remote control service. The whole system consists of ESP 8266 with sensor and Wi-Fi, Firebase as a real-time database, and a smartphone application. This model is divided into functions such as learning mode when the home appliance is operated, learning control through learning results, and automatic ventilation using indoor and outdoor sensor values. The study used moving averages for temperature and humidity in the control of home appliances such as air conditioners, humidifiers and air purifiers. This system can provide higher quality service by analyzing and predicting user's characteristics through various machine learning and deep learning.

This study is about finding effects of home appliances to home furnishing. Recently, home appliances go beyond smart by technology development to show design integrated with furniture. Accordingly, this study is First, from the perspective of home furnishing, I examined the meaning of living space for millennial. Second, I investigated home appliances that recently released for millennial, and analyzed appliances trends, focused on product concepts and styling keyword. Third, conducted in-depth interview focusing on four parts : meaning of space, experience of home- furnishing, appliance and interior, feeling of current appliances. Research has shown that design considered space relevance can make home appliances the main of interior. Future studies will need to validate quantified statistical data. Through this study, I hope that will help to set the role and design direction of home appliances in the future.
