The human vision system has visual functions for viewing 3D images with a correct depth. These functions are called accommodation, vergence and binocular stereopsis. Most 3D display system utilizes binocular stereopsis. The authors have developed a monocular 3D vision system with accommodation mechanism, which is useful function for perceiving depth.

건축을 비롯한 디자인 분야에서 인간중심의 디자인이라는 패러다임의 전환에 부응하는 경향이 조성되고 있으며, 건축분야에서 인간의 감각과 감성에 대한 고려가 필요함을 인식하게 되었다. 그러나 그동안의 건축디자인에서는 이러한 점을 고려한 연구와 디자인 성과의 대부분이 시각 중심으로 편중되어 왔다고 볼 수 있다. 이에 따라 본 연구에서는 디자인 측면에서 인간이 대상을 인지하는 데는 여러 가지의 감각을 동원하게 되고 이의 통합결과로 인지하게 된다는 것을 이해하였고, 특히 문화적 배경과 인간중심의 경향을 보이는 다감각을 고려하고 적용한 미래지향적인 감성디자인 연구가 미흡한 실정에 있다는 점을 주목하였다. 공감을 불러 일으키는 디자인이 감성디자인이며 이의 인식과 적용이 디자이너에게 중요한 과제로 부각되고 있는 만큼, 건축 디자인에서도 인간 중심적인 경험과 감각, 감성의 감흥을 바탕으로 계획되어야 할 것이다. 다감각적 면에서 인간중심의 감성디자인이란 시각에 편중되지 않고 촉각, 청각을 비롯한 여러 감성요소들이 통합된 관점에서 공감적 대상으로서 건축 디자인에 적용되어야 할 것이다.

The environment refers to what is surrounded by something during human life. This environment is related to the way humans live, and presents various problems on how to perceive the surrounding environment and how the behaviors that constitute the environment support the elements necessary for human life. Humans have an interest in the supportability of the environment as the interrelationship increases as humans perceive and understand the environment and accept the factors supported by the environment. In space, human movement starts from one space to the next and exchanges stimuli and reactions with the environment until reaching a target point. These human movements start with subjective judgment and during gait movement, the spatial environment surrounding humans becomes a collection of information necessary for humans and gives stimulation. will do. In this process, in particular, humans move along the movement path through movement in space and go through displacement perception and psychological changes, and recognize a series of spatial continuity. An image of thinking is formed[1]. In this process, spatial experience is perceived through the process of filtering by the senses in the real space, and the result of cognition is added through the process of subjective change accompanied by memory and knowledge, resulting in human movement. As such, the spatial search behavior begins with a series of perceptual and cognitive behaviors that arise in the process of human beings trying to read meaning from objects in the environment. Here, cognition includes the psychological process of sorting out and judging what the information is in the process of reading the meaning of the external environment, conditions, and material composition, and perception is the process of accepting information as the first step. It can be said to be the cognitive ability to read the meaning of the environment given to humans. Therefore, if we can grasp the perception of space while moving and human behavior as a response to perception, it will be possible to predict how to grasp it from a human point of view in a space that does not exist. Modern people have the theme of reminiscing dog-friendly hotels for the healing of petloss syndrome, and this thesis attempts to approach the life of companions.

시청자들은 영상을 시청할 때 화면상 시각이 집중된 곳 주변의 정보를 영향력 있게 받아들일 가능성이 크다. 이러한 사실을 이용하여 최근 연구들은 시각 주의 모델을 영상 제작 및 평가 방법에 이용하고 있다. 본 연구에서는 실제로 사람들의 시각 주의도가 어떠한 인자에 영향을 많이 받는지, 또 시각 주의 모델은 구체적으로 어떠한 형태가 되는지를 통계적 실험 계획법을 이용하여 추정하였다. 분산 분석법을 이용하여 속도, 화면으로부터의 거리, 비초점흐림 정도가 시각 주의에 영향을 미치는 유의한 인자인 것을 확인하였고 반응 표면 계획법을 이용하여 이 세가지 인자들에 따른 시각 주의 점수 모델을 도출하였다. 이 시각 주의 점수 모델로부터 영상 각 픽셀의 시각 주의 확률을 구하였다. 본 연구의 뒷부분에서는 시각주의 확률 모델을 기존의 기울기(gradient) 기반 3차원 영상의 입체감 측정법에 적용하는 방법을 제안하였다. 화면 상에서 시선을 집중할 확률이 큰 부분에 높은 비중을 둠으로써 기존의 방법 보다 시청자가 느끼는 입체감을 더욱 정확하게 측정할 수 있도록 하였다. 제안한 방법의 성능을 검증하기 위해 주관적 평가를 실시하여 피실험자들이 느끼는 입체감과 제안된 방법으로부터 도출한 결과를 비교하였다. 실험 결과 제안한 방법이 기존의 방법에 비해 성능이 높은 것을 확인하였다.

First, we can define how our body perceives the external world and embodies its senses through the philosopher Merleau - Ponty. These philosophical orientations of Merleau-Ponty also appear to urban theorists such as Jane Jacobs, Gordon Cullen, and Juhani Pallasmaa. In other words, after the Second World War, people began to pay attention to human emotions and perceptions while opposing human rational thinking. Especially, they reject the abstract space of modernism and explore the everyday city space where the local character of the area lives. This place is a space where the collective memory of the group is shared over several generations. So, in this space, people's active perceptual system works actively. In the sense of this continuity of time, their ideas intersect with the concept of urban. Specifically, Jacobs criticizes massive development and proposes the development of a small block-based city with a commonality of old and new. In addition, we argue that urban space can be a visually interesting object through the continuous visual concept of urban theorist Cullen. In particular, he rediscovers the value of traditional urban space through visual experience between architecture and urban facilities. Finally, the architectural city theorist, Pallasmaa., criticizes the visual centrality of modern cities and thinks about the value of multidisciplinary space that can be experienced in architecture. This study examines the space of reproduction in detail on the perspective of the body philosophy and urban theorists. In other words, the play space inherits the natural city time, so when our body experiences this play space, we can actively sense and perceive the various senses. So we can invoke the active external actions of our bodies. Through the analysis of the size of the reconstruction space of the architectural city, various types of body senses and responses can be. Yoon Dongju Literary Museum, which renovated the old water tank of the city, can recognize the unfamiliar sense of body in everyday life through the traces and smells of water in the past and the restrained visuality. In addition, Seonyudo Park, which regenerates the waste water purification plant, can experience a phenomenal phenomenon through water space, old concrete and traces of steel. Finally, with the most recently played Seoul Road 7017 can experience interesting urban spaces in terms of a variety of plants, a human scale space creating movement, and a continuous visual.

The purposes of this research are to correctly understand the relationship between a visual communication structure and a semantic communication structure when integrating and changing various architectural visual information. This study will classify various diagrams, which have been actively applied to the works of Rem Koolhaas and MVRDV when designing architecture, and based on the classification, it will analyze how the expression viewpoints inherent in the diagrams are changed and applied to processing and changing architectural visual information. The transformal usage of the visual information of architectural diagrams is classified into an analysis-centered processing method and a concept-centered processing method, and the characteristics of their usage are analyzed. The former shows an observer-centered expression viewpoint which effectively delivers an architect's analyzed architectural information or intent to a customer or an observer. It also allows an easy perception of the analyzed data, and uses qualitative expression viewpoints. The method combines systematic expression viewpoints, which value a relationship with visual information, and various architectural visual information; uses the combined expression viewpoints as one diagram for delivering various information simultaneously and for changing visual information. The latter shows author-centered subjective expression viewpoints, which are different from reproduction-centered fixed expression viewpoints. This method uses arbitrary expression viewpoints that overly extort, change or manipulate visual information. It shows simultaneous expression viewpoints that integrate various architectural visual information via omniscient expression viewpoints, such as reversing or projecting the points of viewing subjects, which human beings cannot perceive.

Human dummies are essential tools in the development of such products as vehicle have been actively used not only in reach and view field tests. but also in impact perception evaluations. This study attempted to obtain geometric and dynamic model body segments from Korean anthropometric data. The investigation focused on the de both human and dummy for the geometric and inertial properties. The dynamic modeli being suggested is based on rigid body dynamics using fifteen individual body segments by joins. The segments are connected at the locations representing the physical joint body so that each segment has its mass and moment of inertia. For visual three-dimensional graphic was used for easier implementation of the dumn applications. For applications, proposed Korean dummies Were used in dynamic crash and driver's view and reach test modules were developed in virtual environment.

This study presents the new method which can transfer the expert's skill to deburring robot through neural network. The expert's skill is expressed as associationmapping between the characteristics of the burr and human expert's action. Under the fundamental idea that the state of the deburring processcan be extracted via the visual sense of the human,we employ vision system for the perception and identification of the changing burr. Form the demonstration of human experts, force data are measured. Finally the characteristics of the burr and coressponding force are associated by the neural network which is trained through many demonstrations. The proposed method is verified in the deburring process of welding burr.
