성백재(Baekjae Sung),박찬익(Chanik Park) 한국정보과학회 2010 정보과학회 컴퓨팅의 실제 논문지 Vol.16 No.1

Stateless computing[1,2]은 컴퓨팅 환경의 이동성을 용이하게 지원하는 기술로써, 여러 사용자들이 컴퓨팅 자원을 공유하는 환경에서 각 사용자 별 보안성을 확보하는 주요 기술로 자리잡고 있다. 또한 최근 가상화 기술의 확산 및 cloud computing의 발전에 따라, 사용자가 사용하는 설정과 데이터들(state)을 원격의 서버등과 같은 임의의 저장장치에 저장 후, 향후 어떠한 환경에서든 저장된 내용을 복원하여 사용자의 computing 환경을 이어가는 개념을 지원하기 위한 핵심적인 요소이다. 본 논문에서 제안하는 uPC player는 사용자에게 Windows 운영체제 환경에서의 Stateless computing 실행환경을 지원하는 기술로써, uPC player는 OS 기반 가상화 모듈인 uPC[3,4]를 기반으로 사용자에게 Windows 운영체제 컴퓨팅 환경을 지원한다. 본 논문에서는 Stateless computing 실행환경을 지원하기 위해 uPC player를 어떻게 설계하고 구현하였는지 설명한다. uPC player는 Windows desktop 환경과 연동하여 호스트 시스템의 실행환경과 uPC 가상 실행환경을 자유롭게 이동 가능하며, OS 기반 가상화 모듈에 기반함으로써 uPC player를 이용한 사용자 실행환경을 지원하는데 소요되는 시간이 약 1초 정도이다. Stateless computing supports a mobility of computing environment easily. It is becoming a major technology for securing personal user’s information on shared computing environment. With the advance of virtualization technology and cloud computing, stateless computing is an essential part of personal computing environment connectivity (user’s setting and data is stored in remote server or some storage, and it can be restored at any computing environment) In this paper, we propose uPC player that supports stateless computing execution environment on Windows. uPC player provides Windows operating system to user by using an uPC OS virtualization module. In this paper, we leverage how uPC player is designed and implemented for supporting a stateless computing execution environment. uPC player provides a desktop switch between host-system execution environment and uPC virtual execution environment. And it needs just one second for loading uPC virtual execution environment by using OS virtualization-based technique.

Ubi-com에서의 GUI(graphic user interface)와 TUI(tangible user interface)비교분석에 관한 연구

최재희(Choi, Jae Hee) 한국디자인지식학회 2007 디자인지식저널 Vol.4 No.-

현재 유비쿼터스 컴퓨팅 분야에서 중요한 연구 과제 중 하나가, 사용자 연구에 따른 적합한 인터페이스를 제공할 수 있도록 하는 것이다. 디지털 환경에서는 컴퓨터가 외부로 노출 적으로 드러나 있는 반면 유비쿼터스 환경에서는 컴퓨터가 그 자체의 모습을 잃고 눈에서 사라지는 컴퓨터가 될 것이다. 이는 모든 사물에 컴퓨터가 심어질것이며 심지어 입는 컴퓨터나 먹을 수 있는 컴퓨터 까지 생겨날 수 있다는 예시이다. 현재 우리는 거의 마이크로소프트윈도우를 통한 컴퓨터를 사용하고 있으며 이에 따른 인터페이스로 GUI(Graphical User Interface)를 사용하고 있다. GUI 에 기반을 둔 HCI(Human Computer Interface)는 전면부에 있는 사각형 스크린위에서 시각적 형태로 모든 정보들을 표현 한다. 따라서 그 자신을 매우 제한된 의사소통 채널로 국한 시키고 있다. GUI는 사람들이 평생 동안 실제 세계와의 상호작용을 통하여 발전시켜온 인간의 감각과 기술의 풍부함을 포용하기에는 모자란 감이 있다. 특히 유비쿼터스 환경에서는 차원이 다른 디지털 인터페이스를 요구하고 있으며 사이버공간과 실제공간을 잇는 ‘제3공간’을 표현하기에는 더더욱 어려움이 있다. 이를 극복하기 위하여 디자인을 비롯한 여러 분야에서 새로운 인터페이스 및 인터렉션 방식에 대한 연구가 진행되고 있다. 그 대표적 예가 TUI(Tangible User Interface)이다. TUI는 인간이 실생활에서 오랜 시간 발전시켜온 감각과 운동을 인터페이스에 적용시키고자 한다. 즉, 실재로 물건을 만지고 느끼고 잡고 옮기는 등의 행위를 통해 디지털 정보를 조작하는 것이다. TUI는 현재 광범위하게 사용되고 있는 GUI모델들, 즉 편평한 사각형의 디스플레이, 윈도우, 마우스 및 키보드 등으로 구성되어 있는 컴퓨터의 한계를 넘어서는 구체적인 방법을 보주는 것이라고 할 수 있다. TUI는 새로운 디지털 인터페이스로 관련 산업, 기술, 제품의 위상을 변화시키고 유비쿼터스 문화의 새로운 요소로 자리 매김을 할 것이다. In response to the recent explosive development of computer technology and its ubiquity, changes in user technologies, and the limitation of graphic interface, the new trend of HCI (human computer interaction) is emerging in the area of interface design. Reserch on HCI is mainly focused on finding fundamental solutions for overcoming conventional interface relying on monitor, mouse and keyboard. However, such solutions must not be limited to convenient and easy input methods but should reflect various human abilities to control and sense, which have been overlooked in traditional computing. In ubiquitous computing environment, GUI (Graphic User Interface) based on flat rectangular displays of desktop computers will evolve no longer. Its new alternative TUI (Tangible User interface) is characterized most by ‘touching interface.’ Till assigns physical shapes to digital information using artifacts that can be expressed and manipulated. Through the interface, information, which has been confined within the computer, can be viewed, touched and heard as a part of life in our everyday life. Ubiquitous interface does not need to rely on vision only. It should be able to use all human senses. People should be able to see, hear, smell and feel the computer. Interface should be designed in a way that the user can recognize things and events spatially and temporally. Approach to TUI must be preceded by understanding the evolution of computing and reflect the changes. which resembles the evolution, which has been made by active reaction on the environmental change. It is the time to find the intrinsic nature and the solution of design from the viewpoint of social evolution.

Ubiquitous Computing and Statistics; What's the Connection?

Jun, Sung-Hae,Jorn, Hongsuk 한국통계학회 2004 Communications for statistical applications and me Vol.11 No.2

Mark Weiser introduced ubiquitous computing in his article titled 'The computer for 21st Century' in 1991. This has been new paradigm after internet. Now, the rapid development of mobile computer, wireless network, and intelligent system has supported ubiquitous computing environment. In the related area of information science, the researchers have studied on ubiquitous computing. But in the field of Korea statistics, this research has not been worked yet. So, we proposed the connection between statistics and ubiquitous computing in this paper. As an example, we showed an efficient cache hoarding for ubiquitous computing using statistical methods. In experimental results, we verified our proposed issue.

Kyoungmin Doo,Youngsam Kim,Samhyun chi,Kangwhan Lee 대한전자공학회 2008 ICEIC:International Conference on Electronics, Inf Vol.1 No.1

Ubiquitous Computing System is available anytime, anywhere communications and computing systems, and information sharing and mutual cooperation between computing systems. Existing computing environment is interactive operation between user and computer. But, The Ubiquitous Computing System required to be aware of physical environment situation oneself. In addition, For Ubiquitous Computing System, it is need the sensor technology to detect information of users and the surrounding environment. But, the user and the surrounding environment input is uncertain and ambiguous information. And Research is not enough awareness about the situation. For these reasons, this paper proposed CRS (Context Recognition Switch) and DOS (Dynamic and Optimal Standard) based Context-awareness system architecture. It included following three main part of architecture. First, it included pre-processor for multi sensor of bio and environment. Second, it included HPSP (High Performance Speed Processor) for real time process. At last, it included Network Topology Processor for Network System as like MANET (Mobile Ad-hoc Network). Finally, this paper show implemented UoC (Ubiquitous System on Chip) base on the IEEE 802.15.4 WPAN (Wireless Personal Area Network) standard.

Inter-space Interaction Issues Impacting Middleware Architecture of Ubiquitous Pervasive Computing

Shinyoung Lim,Sumi Helal 한국지능시스템학회 2008 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.8 No.1

We believe that smart spaces, offering pervasive services, will proliferate. However, at present, those islands of smart spaces should be joined seamlessly with each other. As users move about, they will have to roam from one autonomous smart space to another. When they move into the new island of smart space, they should setup their devices and service manually or not have access to the services available in their home spaces. Sometimes, there will conflicts between users when they try to occupy the same space or use a specific device at the same time. It will also be critical to elder people who suffer from Alzheimer or other cognitive impairments when they travel from their smart space to other visited spaces (e.g., grocery stores, museums). Furthermore our experience in building the Gator Tech Smart House reveals to us that home residents generally do not want to lose or be denied all the features or services they have come to expect simply because they move to a new smart space. The seamless inter-space interaction requirements and issues are raised automatically when the ubiquitous pervasive computing system tries to establish the user's service environment by allocating relevant resources after the user moves to a new location where there are no prior settings for the new environment. In this paper, we raise and present several critical inter-space interactions issues impacting middleware architecture design of ubiquitous pervasive computing. We propose requirements for resolving these issues on seamless inter-space operation. We also illustrate our approach and ideas via a service scenario moving around two smart spaces.

The conventional computing is a centralizing system, but it has been gradually going to develop ubiquitous computing which moves roles away from the main. The Community Computing, a new paradigm, is proposed to implement environment of ubiquitous computing. In this environment, it is important to accept the user demand. Hence in this paper recognizes pattern of user's activity statistically and proposes a method of pattern estimation in community computing. In addition, user's activity varies with time and the activity has the priority. We reflect these. Also, we improve accuracy of the method through Knowledge Base organization and the feedback system. We make program using Microsoft Visual C++ for evaluating performance of proposed method, then simulate it. We can confirm it from the experiment result that using proposal method is better in environment of community computing.
