A Kansei Engineering Research on Garden Design Healing Human Spirit

我们总是受到来自外界环境的“压力”。自然环境对人的身心健康有着重要的影响，而住宅园林又是最贴近人类生活的。本研究的目的是明确花园对人脑的影响。如果这是真的，我们的研究，以找到什么类型的园林设计将给予人类的舒适和愈合的感觉，从人类大脑的观点。简单而朴素的花园被认为是非常有效的舒适。其次，从150幅园林图片中筛选出“我们有治愈的感觉”、“鸟儿来了”等26个不同的感性词语和47幅不同的园林图片。采用感性文字5点SD量表对园林图片进行评价实验的学生和园林工作人员总人数。评价数据采用因子分析和数量化理论I型进行分析，以获得感性和园林设计元素（项目/类别）之间的关系。园林设计元素是指树木（高或低）、石头（大或小）、灌木、池塘的部分，包括日本式园林或美国式园林。我们获得了与特定感性相关的详细设计规范。利用这些数据，园林公司能够创建完整的花园，客户会感到满意。最后，我们试图创建三维智能计算机系统，可以自动绘制三维花园使用感性数据。在这个虚拟现实计算机系统中，最重要也是最困难的问题是如何将树木、石头等物体以三维结构显示出来。我们完成了能够使用感性数据显示三维花园的智能计算机系统的制作。

We always receive "stress" from outside environment. Natural environment have influence of healing to people and house garden is most close to human living. The purposes of the present research are to make clear the garden influence on human brain (EEG). If it is true, our research to find what type of garden design will give human comfort and healing sense from the viewpoint of human brain. The simple and plain garden was found to be very effective for comfort. On the other hand, the complicated garden with a variety of bush is not comfortable on the brain.Secondly, we chose 26 different kansei words like "we have healing feeling", "birds are coming", and 47 different garden pictures from 150 garden pictures. Total number of subjects of students and garden staff jointed to evaluation experiment of garden pictures with 5-point SD scale of kansei words. The evaluated data were analyzed by Factor Analysis and Quantification Theory Type I to obtain the relations between the kansei and garden design elements (Item/Category). Garden design elements mean the parts of trees (higher or lower), stones (large or small), bush, pond, including Japanese type garden or American type. We obtained the detail design specifications related the specific kansei. Using these data, the garden companies are able to create the complete gardens with which the customer will be satisfied.Finally, we tried to create 3dimensional intelligent computer system which is automatically able to draw the 3 dimensional garden using the kansei data. The most important and hard problem in this virtual reality computer system is to illustrate trees and stones and all other item in 3-dimensional structure. We completed to make the intelligent computer system which is able to show the 3-dimensional garden using the kansei data.
