This research aims to develop fundamental design methodologies for human space and product design by motion capture of human activity. It is intended to generate new geometry using a motion capture system as design input device and then to develop it to design interior space and products such as furniture from data extracted from human motion. In order to produce a ubiquitous and comfortable environment, performance modeling focusing on the relationships between space and physical motion is needed. Making an object of complex shape is thought to be a new application of motion capture technology. This research proves that the numeric data of body actions can be transferred and developed to object shapes.

The urban planning has largely placed the street users at the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. The urban designers faced with the task of designing such spaces and needs a tool that will allow different designs to be compared in terms of their attractiveness as well as their effectiveness. Therefore, this paper depicts an agent interface approach for creating a street simulator of user behaviors in urban street environments. We implemented the agent interface as individual-based simulation in the proposed project called "SCALE” (A Street Case Library for Environmental design). The project is demonstrated to find out differences between the simulation and the existed environment. The methodology and findings are reported.

A potential way to bridge the gap between complex form generation and models for physical manifestations is to panelize NURBS surfaces with polygonal faces. This paper investigates the transition from NURBS surface to a mesh solid through a procedural modeling approach, in the process, illustrating how a discretized planar surface can be reconstructed for form generation and further exploration. The paper promotes this approach as an efficient way to modeling complex forms using an example drawn from real life architecture to demonstrate a generative process with customized restructuring.

This action research project develops a novel conceptual method for non-standardised concrete construction component fabrication and tests its validity through a speculative design project. The paper questions the practical, procedural and economic drivers behind the design and construction of geometrically complex concrete architecture. It proposes an alternative, simple and economical fabrication method for doubly curved concrete centred on the robotic manufacturing of casting moulds through 5-axis hotwire foam cutting for the making of doubly-curved fiber-reinforced concrete (FRC) panels. These panels are used as light-weight sacrificial formwork for in-situ concrete casting. The methodology's opportunity space is tested, evaluated and discussed through a conceptual architectural design project proposal that operates as demonstrator. The paper concludes by addressing the advantages of a design-and-build architecture delivery setup, the potential from using computational technology to adapt conventional design and construction procedures and the expanded role within the design and construction process this gives to architects.

A relationship between spatial frequency magnitude and aesthetic preference for texture is established in this work. This paper examines the mean output of three frequency settings in terms of preference ratings for a bank of Gabor filters. Three studies were conducted and the correlations between aesthetic ratings and the mean output for the filter set to extract frequency content at the scale of 0.35 cycles/ pixel were robust. The correlations for the mean frequency magnitude of this filter remained significant when image identifiability was incorporated; suggesting that memory and association are not exclusively driving (aesthetic) preference. These results are consistent with findings reported by Albrecht and Geisler (1997), demonstrating that human beings are tuned to specific frequencies and orientations. Overall, the results reported in this paper begin to substantiate a claim that specific frequencies contained in images do play a significant role in human preference. 1. Goodness of Form Prägnanz Early in the last century the quality of a visual experience was approached by Gestalt psychologists through the analysis of ‘goodness’ of form, or prägnanz, whichin their opinion was an important factor in perceptual experience (Beardslee et al., 1923; Kofka, 1922; Mowatt, 1940; Kohler, 1947). Perceptual “experience” was said to correspond to global properties of subjective simplicity, complexity and bilateral symmetry. Researchers did not believe whole figures could be understood by means of examining the local properties of those figures. Some images were thought to produce experiences of greater simplicity, order and regularity than others. Stimuli that are simple (contain adequate redundancy), symmetric (rotationally invariant) and familiar were considered “good”. However, a reliable description for judged simplicity was not determined and the relationship between symmetry and figural “goodness” (prägnanz) was not demonstrated. Symmetry proved only to be a tenable explanation and local asymmetry was not addressed (Garner 1962, 1970).
在这项工作中建立了空间频率大小与纹理审美偏好之间的关系。本文根据一组Gabor滤波器的偏好评级，研究了三种频率设置的平均输出。进行了三项研究，美学评级与滤波器集的平均输出之间的相关性在0.35周期/像素的尺度下提取频率内容是鲁棒的。当考虑图像可识别性时，该滤波器的平均频率幅值的相关性仍然显著;这表明记忆和联想并不是唯一驱动(审美)偏好的因素。这些结果与Albrecht和Geisler(1997)报告的结果一致，表明人类被调谐到特定的频率和方向。总体而言，本文报告的结果开始证实图像中包含的特定频率确实在人类偏好中起着重要作用的说法。1. 形式的善Prägnanz早在上个世纪初，格式塔心理学家就通过分析形式的“善”(prägnanz)来研究视觉体验的质量，在他们看来，形式的善是感知体验的一个重要因素(Beardslee et al.， 1923;Kofka, 1922;Mowatt, 1940;科勒,1947)。知觉“经验”被认为与主观的简单性、复杂性和双边对称性的整体特性相对应。研究人员不相信通过检查这些图形的局部特性可以理解整个图形。一些图像被认为比其他图像更能产生简单、有序和规律的体验。简单(包含足够的冗余)、对称(旋转不变)和熟悉的刺激被认为是“好的”。然而，对于判断简单性的可靠描述并没有确定，对称和图形“善良”之间的关系也没有得到证明(prägnanz)。对称被证明只是一种站得住脚的解释，而局部不对称没有得到解决(Garner 1962, 1970)。
