The influences of luminous environment on visual responses and fatigue sensation in art galleries were examined in this study. Field measurements and survey were performed in three galleries under various illuminance and luminous conditions. Result implies that vertical illuminance on art paintings needed to be somewhere between 200 lx and 300 lx to avoid visual discomfort. The vertical illuminance difference between consecutive paintings should not exceed 100 lx to keep visually comfortable environment. Visual comfort sensations were related to glare, visual stimulus, reflection from paintings, illuminance variation, and the sensation that subjects can clearly see the paintings. The sensation of fatigue was significantly influenced by the changes of luminous element that caused visual stimulus and discomfort. The sensation of eye fatigue among physical fatigue was primarily influenced by the glare, visual stimulus and comfort. The psychological fatigue was also influenced by eye fatigue, visual comfort, brightness and satisfaction with color of light.

The most popular approach in object classification is based on the bag of visual-words model, which has several fundamental problems that restricting the performance of this method, such as low time efficiency, the synonym and polysemy of visual words, and the lack of spatial information between visual words. In view of this, an object classification based on weakly supervised E2LSH and saliency map weighting is proposed. Firstly, E2LSH (Exact Euclidean Locality Sensitive Hashing) is employed to generate a group of weakly randomized visual dictionary by clustering SIFT features of the training dataset, and the selecting process of hash functions is effectively supervised inspired by the random forest ideas to reduce the randomcity of E2LSH. Secondly, graph-based visual saliency (GBVS) algorithm is applied to detect the saliency map of different images and weight the visual words according to the saliency prior. Finally, saliency map weighted visual language model is carried out to accomplish object classification. Experimental results datasets of Pascal 2007 and Caltech-256 indicate that the distinguishability of objects is effectively improved and our method is superior to the state-of-the-art object classification methods.

Objective: The purpose of this study is to develop visual complexity metrics based on theoretical bases. Background: With the development of IT technologies, drivers process a large amount of information caused by automotive human-machine interface (HMI), such as a cluster, a head-up display, and a center-fascia. In other words, these systems are becoming more complex and dynamic than traditional driving systems. Especially, these changes can lead to the increase of visual demands. Thus, a concept and tool is required to evaluate the complicated systems. Method: We reviewed prior studies in order to analyze the visual complexity. Based on complexity studies and human perceptual characteristics, the dimensions characterizing the visual complexity were determined and defined. Results: Based on a framework and complexity dimensions, a set of metrics for quantifying the visual complexity was developed. Conclusion: We suggest metrics in terms of perceived visual complexity that can evaluate the in-vehicle displays. Application: This study can provide the theoretical bases in order to evaluate complicated systems. In addition, it can quantitatively measure the visual complexity of In-vehicle information system and be helpful to design in terms of preventing risks, such as human error and distraction.

This paper looks at the development of the visual system of robots, and the development of image processing algorism to measure the size of an object and the distance from robot to an object for the visual system. Robots usually get the visual systems with a camera for measuring the size of an object and the distance to an object. The visual systems are accurately impossible the size and distance in case of that the locations of the systems is changed and the objects are not on the ground. Thus, in this paper, we developed robot's visual system to measure the size of an object and the distance to an object using two cameras and two-degree robot mechanism. And, we developed the image processing algorism to measure the size of an object and the distance from robot to an object for the visual system, and finally, carried out the characteristics test of the developed visual system. As a result, it is thought that the developed system could accurately measure the size of an object and the distance to an object.

This study deals with image-based visual servoing for automatic recharging of mobile robot. Because mobile robot must be recharged periodically, it is necessary to detect and move to docking station. Generally, laser scanner is used for detect of position of docking station. CCD Camera is also used for this purpose. In case of using cameras, the position-based visual servoing method is widely used. But position-based visual servoing method requires the accurate calibration and it is hard and complex work. Another method using cameras is image-based visual servoing. Recently, image based visual servoing is widely used for robotic application. But it has a problem that cannot have linear trajectory in the 3-dimensional space. Because of this weak point, image-based visual servoing has a limit for real application. In case of 2-dimensional movement on the plane, it has also similar problem. In order to solve this problem, we point out the main reason of the problem of the resolved rate control method that has been generally used in the image-based visual servoing and we propose an image-based visual servoing method that can reduce the curved trajectory of mobile robot in the cartesian space.

The purpose of this study is to investigate the architectural visual identity, and scheme of conceptional extent of architectural visual identity through literature research and sample analysis by design factors for apartment design. Korea National Housing Corporation's Mapo apartment put first caterer which is continued about 30 years to solve shortage of houses by beginning and the impact of IMF and the price decontrol on second half in the 1990s have changed the housing status to commercial goods. Construction companies have introduced brand concept to satisfy consumer's appetite in production of house goods including apartment under market situation. Importance of visual identity in apartment design occupies has risen in heftily. However most companies are in condition of stay on two-dimensional application that uses symbol, logotype, and character assistance. Several high position construction companies are trying architectural visual identity, but those are applied in partial element and those are not going forward to systematic classification and synthetic visual identity plan within peculiarity of apartment complex. This study is to grasp plan and design tendency to acquire identity of design element of construction field and goods through design examination. In conclusion visual identity in apartment design is architectural visual identity on all of 2 dimensions and 3 dimension for application. Architectural visual identity is a language of form that prescribe identity about external appearance in combination with brand image.

This study investigates the effect of visual merchandising congruity perception on brand attitude and purchase intention. In addition, this study examines the mediating role of perceived risk in the process. Four retail fashion brands with classic image were selected in the previous research to avoid the influence of different brand images. Questionnaires were distributed to 200 customers leaving the four fashion retail stores which were chosen by the previous research. A total of 167 completed questionnaires were analyzed using SPSS 18.0 and AMOS 7.0 statistical packages. The results were summarized as follows. First, visual merchandising congruity perception positively affected brand attitude. This result supports the match-up hypothesis. Second, brand attitude positively influenced purchase intention. Third, visual merchandising congruity perception did not directly affect purchase intention. Visual merchandising congruity perception indirectly influenced purchase intention by mediating brand attitude; however, it did not directly influence purchase intention. Therefore, the strategic approaches to enhance favorable brand attitude through visual merchandising congruity perception should be tried. Fourth, visual merchandising congruity perception negatively affected perceived risk. Fifth, perceived risk negatively affected brand attitude. Sixth, visual merchandising congruity perception affected brand attitude by mediating perceived risk. Therefore, it is needed to devise the visual merchandising strategy that lowers the perceived risk in order to make a positive brand attitude.
