Influence of Movable Elements on Environment Cognition and Behavior

考虑到建筑物的建设和城市的发展所带来的环境变化的心理影响，为了验证我们的想法和概念是否能发挥预期的效果，我们必须事先模拟所设想的环境。首先，通过一系列实验，使用计算机图形学生成的视觉模拟，揭示了行人作为可移动元素在寻路中的效果。结果表明，街道上的人被用作寻路的线索，他们有两个功能。一种是正面功能，行人提供了有效的线索，有助于记忆主体存在的地点。另一个是负面的，一个主题谁记住的路线只依赖于存在的行人迷失方向时，他们消失，他们作为一个视觉噪音，这扰乱了记忆的空间特征。其次，一个新的模拟系统开发，以测试心理影响的可移动元素，使用模拟和数字图像。该系统将实时CG生成的行人、汽车等可动元素叠加到比例模型空间的静态环境背景、视频图像上。对仿真系统的性能进行了初步的实验测试。研究结果表明，可移动元素对空间评价和人们的行为产生了影响。

Considering psychological impact of environmental changes caused by building construction and urban development, we have to simulate the proposed environment in advance to examine our ideas and concepts whether or not they work as expected.Firstly, an experiment was conducted to reveal effects of pedestrians as movable elements in wayfinding by a series of experiments, using visual simulation generated by computer graphics. The results showed that people on the street are used as a clue for wayfinding, and that they have two functions. One is a positive function that pedestrians provide an effective clue and help to memorize a place where the subject exists. Another is a negative one that a subject who memorizes a route depending only on existence of pedestrians loses the way when they disappear and they play as a visual noise, which disturbs memorizing spatial characteristics.Secondly, a new simulation system was developed to test psychological impact of movable elements, using both analogue and digital image. In this new system, such movable elements as pedestrians and cars produced by real-time CG are overlaid on the static environmental background, video image of a scale model space. A preliminary experiment was conducted to test the performance of the simulation system. The results indicate movable elements effects on spatial evaluation and people's behavior.
