For autonomous navigation, map, pose tracking, and finding the shortest path are required. Because there is no GPS signal in indoor environment, the current position should be recognized in the 3D map by using image processing or something. In this paper, we explain 3D map creation technology by using depth camera like Kinect and pose tracking in 3D map by using 2D image taking from camera. In addition, the mechanism of avoiding obstacles is discussed.

This paper proposes a method to detect vanishing points of an indoor scene using line segment classification. Two-stage vanishing points detection is carried out to detect vanishing point in indoor scene efficiently. In the first stage, the method examines whether the image composition is a one-point perspective projection or a two-point one. If it is a two-point perspective projection, a horizontal line through the detected vanishing point is found for line segment classification. In the second stage, the method detects two vanishing points exactly using line segment classification. The method is evaluated by synthetic images and an image DB. In the synthetic image which some noise is added in, vanishing point detection error is under 16 pixels until the percent of the noise to the image becomes 60%. Vanishing points detection ratio by A.Quattoni and A.Torralba's image DB is over 87%.

The traditional illuminance intensity detection method using a single sensor has a problem that uniformity of illuminance detection is deteriorated depending on the measurement position due to the narrow FOV characteristic. In order to overcome this problem, a method of detecting an average illuminance value through a plurality of illuminance sensors is used, but the complexity and detection error are increased. In this paper, we propose a illuminance intensity detection method based on a single image sensor with wide FOV. The proposed method can solve the problems such as system complexity and error increase of existing illuminance sensor. The test results show that the difference of average value is 12% using a illuminance sensor, 10.7% using five illuminance sensors, and 6.2% using an image sensor compared with the reference value using the color difference illuminometer. It is confirmed that the proposed method can easily and accurately detect the space illuminance with improved uniformity.

This study examines potential growth and different perspectives on green-walls, which are being re-evaluated recently. The aim is to identify the viewer preferences concerning the walls by collecting a wide spectrum of information to create an interior design related comprehensive and intellectual database. Also based on this proposition, choosing a green surface of indoor wall as a specific example stimulus, identifying a relationship betweeationsviewer's preference factors. The relationship will formulate detailed and absolute qualities, which will reach potential areas that the green walls can be widely applied in. As a result of a factor analysis, the viewers classified into the 3 factors as is pleasant, gorgeous and rich about the stimulus. Preferred key factors, which are closely related to emotional image language, were; cool, tidy, comfortable and beautiful. The common factors in preferred design stimulus, in order of importance are color>elements>image/form/plants. Specific levels of design factors according to relevance are contrast>furniture> modern>central/creeper foliage plants. In the meantime, this study is leading the process of quantitative measurement of green-walls to a new design direction and it is critical to consistently experimenting to back up the theory with solid evidence.

Modern people come to have high standard and variety need for the oneself expression these days. This phenomenon also, appears in the house space clearly. There are design characteristics in an element expressing a lifestyle and personality in the house space and a living room is the space that is important at time to do a design characteristics plan. Therefore, this study is going to analyze the design characteristics of the apartment house which is a representative house type these days. Concretely, there are design characteristics that a color, an Image, a style. This study used questionary survey from June 10, 2008 to July 9. The color analyzed a color and tone through a color palette of PCIS and the living room image used SD(semantic differential method) method by a concrete analysis method. The result of the analysis were as follows; 1) Various colors and tone were prefer in a house future than the house where lived in. 2) It was done prefer to 'comfort' image for the future living room image in the future but 'provocative' image and 'splendid' were not done a choice 3) A 'modern style' was done prefer to of with a house living room style in the future.

When a certain particular department store is chosen by customers due to the good image, the department store will have provided for the conditions that it can precede in competition with other department stores. Based upon it, a survey was made of preference for the department store interior design image component. In order to make the department store image better based upon this study results, the designer should remember that department store is possessed of display and circultation planinorder to give consume the good image. And , as a result of analyzing customers' preference for the details of the interior design image component, the area, primary components of the department store space, should take on specialization , though narrow. The circulation should constitute the free flow system. The ornamental illumination should be emphasized for the secondary component of the department store space. The color planing should be made that is oriented to seasonality and products. The floor should finished with wood. The department store interior should be decorated in a modern and simple form. The display of the department store should be made in a fashion that it takes on seasonality and artistry. These measures can be said to be the desirable method to provide a good image for women customers paying a visit to the department store.

This study aims to find out various users' diverse interior design needs for their housing and interior design through the personality, which is intrinsic and consistent traits of the individual. The survey research followed the literature reviews including personality studies and interior design assessments. 176 undergraduate and graduate students as controlled by age, sex, and major answered the questionnaire. Their housing and interior design attitudes, the semiotic assessment of interior design styles, and interior design preference were compared in accordance with four pairs of preference dichotomy of MBTI (Myers-Briggs Type Indicator): Extraversion -Introversion, Sensing-iNtuition, Thinking-Feeling, Judging-Perceiving. As a result, the framework of housing and interior design needs by the users' personality types are proposed. It shows specific needs for 16 types of personality based on eight preference dichotomy: extroversion-open, introversion-closed, sensing-functional, intuition-emotional, thinking-restricted, feeling-receptive, judging-simple, and perceiving-creative.

The Department store of today contrary to past plays an important role in the culture of modern market, because of the development of national economy and a rise in the standard of living. The improvement of culture and the high growth of economy made a livelihood fertile, mass production and mass consumption of product based on accumulation of technology caused the industry of distribution to activate, and the change of consumption pattern and various purchasing form resulted in the distribution structure like large scale store. This study was composed of pilot study, the first research, and the second research. In pilot study, the types of interior design the first floor of large-sized department store in the Metropolitan area was classified on the basis of the image of interior design prior researched. The contemporary interior design require unique image frequently because of the qualitative enhancement accompanying segmentation and specialization of space. Especially, the emergence of foreign company along with the change of the distribution environment threaten the domestic interior design industry. Therefore, the interior design plant introducing the image elements is able to have critical influence on forming specialized space in department store. This study investigated the interior design limited to the first floor of large-sized department store in the Metropolitan area, therefore the user's preference and the problem of design in domestic department store of today was not examined well. But this study was able to explore the types of interior design image in the first floor of department store and the relation between consisting elements.
