With various sensor network and ubiquitous technologies, we can extend interaction area from a virtual domain to physical space domain. This spatial interaction is differ in that traditional interaction is mainly processed by direct interaction with the computer machine which is a target machine or provides interaction tools and the spatial interaction is performed indirectly between users with smart interaction tools and many distributed components of space. So, this interaction gives methods to users to control whole manageable space components by registering and recognizing objects. Finally, this paper provides an effective spatial interaction method with template-based task mapping algorithm which is sorted by historical interaction data for support of users' intended task. And then, we analyze how much the system performance would be improved with the task mapping algorithm and conclude with an introduction of a GUI method to visualize results of spatial interaction.

Recently, as the importance of forced indoor living has increased in the untact era, the connection and relationship between space environments is increasing. That is, the smart interaction environment for providing services in various spaces collects and processes a number of surrounding environment information through various sensors to provide desired information according to the required place and time. In this environment, a new type of interaction paradigm is needed for the user to select and focus on environmental information. In this paper, we provide guidelines based on models and patterns for designing various interactions around space. Through interaction model-based technology, we provide guidelines for space-oriented interaction design. We propose an ideal interaction environment through guideline-based patterns and templates. Finally, by providing a space-oriented interaction environment suitable for smart interaction, users can freely obtain desired information.

The interactive display is providing various interaction modes to users through various ubiquitous computing technologies. These methods were studied for their interactions, but the limits that it is provided to only single user and the device usability were generated. In this paper, we propose a new type of spatial multi interaction interface that provide the various spatial touch interactive to multi users in the ambient display environment. Therefore, we generate the interaction surface so that a user can interact through the IR-LEDs Array Bar installed in the ceiling of the ambient display environment. At this time, a user can experience the various interactions through the spatial touch in an interaction surface. Consequently, this system offers the interactive display and interface method that the users can interact through natural hand movement without the portable devices.

Recently, systems providing the interaction different according to an interval between a user and the display were developed in order to construct the ambient or the ubiquitous computing environment. Therefore, we propose a new type of spatial interaction system; our main goal is to provide the interactive domain in the large-scale ambient display environment. So, we divide into two zones of interaction dependent on the distance from the interaction surface interactive zone and ambient zone. In interactive zone, the users can approach the interaction surface and interact with natural hand-touch. When the users are outside the range of the interactive zone, the display shows only general information. Therefore, this system offers the various interactions and information to users in the ubiquitous ambient environment.

In this study, we proposed Context Cube as a conceptual model of user context, and a Multi-modal Interaction Design framework to develop ubiquitous service through understanding user context and analyzing correlation between context awareness and multi-modality, which are to help infer the meaning of context and offer services to meet user needs. And we developed a case study to verify Context Cube's validity and proposed interaction design framework to derive personalized ubiquitous service. We could understand context awareness as information properties which consists of basic activity, location of a user and devices(environment), time, and daily schedule of a user. And it enables us to construct three-dimensional conceptual model, Context Cube. Also, we developed ubiquitous interaction design process which encloses multi-modal interaction design by studying the features of user interaction presented on Context Cube.

Tangible Space is a new emerging interaction space with mobile AR/VR computing and ubiquitous computing environment with IoT. Tangible Space spans from a physical environment augmented with virtual entities to immersive virtual environments mirroring the physical environment. Interacting with Tangible Space is logged just like interacting with the Web. By webizing Tangible Space, we can gain persistence as a by-product so that human life experience in the physical environment can be logged and shared just like the information being created and shared in the current Web. The result is a powerful future direction of the web from a World Wide Web of Information to World Wide Web of Life experiences.

Digital technology makes changes of people's behavior style and characteristic of space in which people live. Therefore, we need to adjust conceptual meaning related to digital technology properly. For deriving emotional interactive space design, we need to understand following meanings: the meaning of interaction and interaction design, the meaning of emotion and emotional design, the meaning of space, emotional design, and interaction design in digital society. Consequently emotional interactive space design makes people satisfied with their five senses, communication with people increase and enable people to experience something new that they haven't experienced before transcending time and space.

3D 디스플레이 기술이 발달함에 따라 3 차원 공간에서의 뇌-컴퓨터 인터랙션 기술에 대한 관심이 높아지고 있다. 3D 디스플레이 기술은 사용자에게 실재감과 몰입감을 부여하여 특정 태스크를 수행할 때 사용자 태스크 퍼포먼스를 향상시킬 수 있다. 이와 같은 3D 입체감이 주는 긍정적 효과에 대한 연구는 교육, 주의력 향상, 엔터테인먼트를 목적으로 하는 뇌-컴퓨터 인터랙션 분야에서도 활발히 이루어지고 있다. 뇌-컴퓨터 인터랙션을 구성하는 뇌파성분에는 시각, 청각, 촉각 유발지속전위, 사건유발전위, 사건관련 동기/비동기화 성분, 느린 피질전위 등이 있다. 이 중 시유발 지속전위를 이용한 뇌-컴퓨터 인터랙션 기술은 오브젝트 콘트롤을 위한 사전훈련이 거의 요구되지 않으며 높은 정보전달율을 가지는 것을 특정으로 하기 때문에 최근 널리 사용되고 있다. 그러나 저주파수 대역의 명멸자극이 유발하는 피로감으로 인해 사용시간이 제한적인 한계점이 있다. 따라서, 본고에서는 유발뇌파의 일종인 시유발지속전위를 이용한 뇌-컴퓨터 인터랙션 기술을 소개하고 3D 홀로그램 인터랙션 수행 시 피로감을 최소화할 수 있는 방안에 대해 논의 하고자 한다.

본 논문에서는 테이블형 가상 공간인 가상워크벤치 상에서 자연스럽고 직관적인 사용자 인터랙션을 이용하여 삼차원 객체를 모델링 하는 방법에 대하여 소개한다 먼저 일반적으로 삼차원 객체를 모델링하기 위하여 많이 이동되는 이차원 스크린 기반의 환경과 삼차원 가상 현신 시스템을 기반으로 하는 환경의 특징에 대하여 살펴본다. 삼차원 가상 현실 시스템을 기반으로 하는 모델링 환경에서는 사용자와의 인터랙션이 삼차원 공간상에서 이루어지기 때문에 직관적이지만 객체를 정확하게 선택하거나 조작하는데 어려움이 따른다. 따라서 이러한 단점을 보완해 주기 위하여 테이블형 가상 공간에서 그리드 기반의 객체 생성 및 스냅핑을 적용한 객체 조작 방법을 제안하고 이의 응용 가능성을 살펴본다.
