Spatial design method for wayfinding using space block notation system

空间区块是一个由墙壁和地板包围的空洞的符号系统，里面有人和树。在这些年里，我们为建筑学学生开发了这个符号作为教育工具。在本研究中，运用空间区块的概念，提出了空间寻路的设计方法。我们将该方法应用于购物空间的寻路。为此，我们进行了如下观察和问卷调查。1996年，我们观察了东京地区一些主要百货公司的人们的行为。1997年，我们对东京和名古屋的大学生进行了关于百货商店空间构成形象的问卷调查。为了直观地描述动作图式，我们引入了事件图标，事件图标表示动作和发生的事情。寻路过程中的事件图标分为三种类型：做某事、获取信息和移动。用成对序列、事件图标和空间块很好地描述了观测数据的方式。这种记号系统不仅能够很好地解释观察到的场景，而且还能够很好地解释规划和记忆的认路场景。我们开始开发这种方法来进行更一般的场景设计。

The space block is a notation system of a void surrounded by walls and floors with people and trees in it. We developed this notation for education tools for architectural students, during these years. In this research, using this concept of space block, spatial design method for wayfinding is proposed. We apply this method for the wayfinding in shopping spaces. For this purpose, observation and questionnaire surveys were conducted as follows.In 1996, we observed people's behaviors in some major department stores in Tokyo area. This shows that there are some standing patterns of wayfinding behaviors in the shopping space.In 1997, we conducted questionnaire surveys about the image of the spatial composition of department stores on university students in Tokyo and Nagoya. From this survey, schema for actions, spaces and their relationships are made clear.For visually describing action schema, we introduce event icons, which mean actions and happenings. Event icons during wayfinding are classified into three types : to do something, to get information, and to move. Waydinding data from observation survey were well described using the sequence of pairs, an event icon and a space block. This notation system is well able to explain not only observed scenes, but planned and remembered scenes of wayfinding as well.We began to develop this method for more general design about scenes.
