The study of the expression of architectural glass has recently expanded due to various factors such as the development of architectural technology, the reinforcement of environmental standards, an increased interest in energy saving, and the commercialism of the exterior of buildings. The background for restoring the tactile capability of the sense of sight has been prepared by agitating oculocentricism pertaining to the Renaissance era. The restoration of tactility can be considered in two ways. One is the tactility 'perceived' through complex experiences and the other is the tactility 'sensed' from the challenges on the materiality of the glass itself. Perceptual tactility is achieved from compound visual experiences and connecting these complex experiences in the brain. Sensible tactility, in contrast to perceptual tactility, is a more direct tactility which works within the nervous system, bypassing the brain. This is attained by reversion of the materiality, tectonics and connection method of the glass. Among rare examples, Laminata House built in Leerdam, Netherlands is a fine example of direct and sensible tactility. In this paper, the process of restoring tactility in architecture is studied at each stage based on the restoration of tactility in painterly aesthetics.

Recently the trend that human emotions become central is strongly on the rise beyond functions in the area of space. In the present situation, the current study is to examine the characteristics of experiential space of emotions through an approach to space appearing in kinetic art paying attention to the fact that the new spatial expressions and forms of Kineticism lie in introduction of 'movement' as a phenomenon that humans who are main agents of experiences can perceive. For research methods, spatial expressions were proposed according to each characteristic extracting characteristics to create space through 'movement' of Kineticism, and the features of experiential space of emotion were elicited by analyzing sensible elements and perceptual characteristics which stimulate human sensitivity through expressive aspects of 'movement' appearing in the case. As a result, it was found that characteristics appeared including immersion through non-daily stimulation, empathy through visual·perceptual stimulation, syn-aesthetic experiences through stimulation of thinking senses, and perceptual activation through physical movement etc. Namely, the present study has its meanings in seeking another directions and possibilities as emotional space to activate experiencers' diverse perceptions and senses by analyzing the characteristics of experiential emotional space through 'movement' of Kineticism which is one of modern plastic arts.

Design is inseparably related to aesthetics. In spite of that, it is difficult to explain the precise aesthetic variables that affect the aesthetic value of space or environment. Therefore, this study intended to find the relationships between aesthetic variables by perceptual and affective judgement for space design with focus on complexity and preference variables. The research found low level of 'arousing' as well as high levels of affective dimension variables 'pleasant' and 'relaxing' evoked high preference. High preference also appeared in space design cases with high unity, order, and clarity with low contrast and complexity, which are variables of perceptual dimension. Complexity, one variables of preference by Kaplan, is in an inverse proportion to space preference. Thus, space design with high complexity has high level of 'exciting' and 'arousing' affective responses and relatively low level of 'relaxing' response. Additionally, it was confirmed that the most importantly influential factor on complexity was diverse components rather than visual richness and ornamentation.

Purpose : This study examined the hand function and visual motor integration capabilities in 30 children with developmental disabilities. The children were divided into an experimental group (n=20) that received digital sensory perception training and a control group (n=10) that did not receive this training. Methods : Training was conducted a total of 12 times for six weeks, for 50 minutes a day, twice a week, for the experimental group. The Jebsen-Taylor Hand Function Test was used to determine the hand function before and after the intervention, and the Beery VMI-6 was performed to identify the visual motor integration capability. Results :After the intervention, the ability to perform hand functions and visual motor interaction increased significantly in the experimental group but not in the control group. Digital sensory training therefore had a positive effect on the hand function and visual motor integration in children with developmental disabilities. Conclusion : A digital sensory perception training program is an arbitration method that can positively improve the hand function and visual motor integration ability in children with developmental disabilities.

This paper reports on the ACQA(Animated agent for Conversational Question Answering) project conducted at LIMSI. The aim is to design an expressive animated conversational agent(ACA) for conducting research along two main lines: 1/ perceptual experiments(eg perception of expressivity and 3D movements in both audio and visual channels): 2/ design of human-computer interfaces requiring head models at different resolutions and the integration of the talking head in virtual scenes. The target application of this expressive ACA is a real-time question and answer speech based system developed at LIMSI(RITEL). The architecture of the system is based on distributed modules exchanging messages through a network protocol. The main components of the system are: RITEL a question and answer system searching raw text, which is able to produce a text(the answer) and attitudinal information; this attitudinal information is then processed for delivering expressive tags; the text is converted into phoneme, viseme, and prosodic descriptions. Audio speech is generated by the LIMSI selection-concatenation text-to-speech engine. Visual speech is using MPEG4 keypoint-based animation, and is rendered in real-time by Virtual Choreographer (VirChor), a GPU-based 3D engine. Finally, visual and audio speech is played in a 3D audio and visual scene. The project also puts a lot of effort for realistic visual and audio 3D rendering. A new model of phoneme-dependant human radiation patterns is included in the speech synthesis system, so that the ACA can move in the virtual scene with realistic 3D visual and audio rendering.

This research regards that experiencing certain space according to looking through sensations of body will finally make visual perceptional experience to happen. Our bodies incorporate sensible experience along with interactions with surrounding environment while making movements. The analysis of Seongyojang in Gangleung through top and bottom, depth, movement and experience space which are Merleau Ponty's phenomenological space elements has led to the following conclusions. First, the up and down directivity inherent in Seongyojang has different directions in movements by the axis of plane. Second, the depth by the correlation between things and bodies shows the interactions with things and the depth of space rendered by the servants' quarters of '一字形' and the overlapping effect from the movement between buildings can be seen and felt. Third, mobility is focused on the surroundings for the movements of body and thing. Fourth, the experienced space remains as what it is and is experienced through the experience of traditional cultures. The temporality where the past and the present subsist is given with the application of the modern living pattern in the traditional space. That is, the space from the point of phenomenological view makes the visual-perceptual experience possible through the senses of body, with which the space is experienced and sensed. In other words, the space from the phenomenological viewpoint makes visual-perceptual experience possible through the senses of body so that the space may be experienced and perceived. Through this study, a new viewpoint toward Korean traditional space is expected to be discovered.

Objective image quality assessment (IQA) models have been developed by effective features to imitate the characteristics of human visual system (HVS). Actually, HVS is extremely sensitive to color degradation and complex texture changes. In this paper, we firstly reveal that many existing full reference image quality assessment (FR-IQA) methods can hardly measure the image quality with contrast and masking texture changes. To solve this problem, considering texture masking effect, we proposed a novel FR-IQA method, called Texture and Color Quality Index (TCQI). The proposed method considers both in the masking effect texture and color visual perceptual threshold, which adopts three kinds of features to reflect masking texture, color difference and structural information. Furthermore, random forest (RF) is used to address the drawbacks of existing pooling technologies. Compared with other traditional learning-based tools (support vector regression and neural network), RF can achieve the better prediction performance. Experiments conducted on five large-scale databases demonstrate that our approach is highly consistent with subjective perception, outperforms twelve the state-of-the-art IQA models in terms of prediction accuracy and keeps a moderate computational complexity. The cross database validation also validates our approach achieves the ability to maintain high robustness.

Image display is the last step of imaging chain in which the diagnostic information is transformed into perceivable intensities and transformed to observer's eye-brain system. In this process, a certain part of information may be efficiently transfered and another part may be inefficiently transfered leading to information loss. In this study, the visual perceptual properties of image display on CRT monitor has been investigated. Psychophysical experiment of target image detection has been performed using CRT monitor for various background grey levels, and the threshold difference grey levels required for visual discrimination have been predicted by computer simulation with visual model.

Territory is determined by physical elements that provide the occupants an obvious boundary in a space. The creation of boundary is a interpersonal process by which a person or group regulates interactions with others. The perception of territory needs boundary regulations that mean the composition of horizontal and vertical elements in architectural space. The perception of territory can be defined as perceptual reaction considering not only visual perception on the physical elements in the architectural space and also various kinds of social activity in architectural environment. To achiever territory in architectural space, visible and invisible boundary regulation should be need. It means that territorial boundary regulation needs visual and audial boundary regulation as well as spatial boundary regulation.
