2 A shape transformation is regarded as Substitute element only if the added shape is new, meaning that it has not been achieved through any other type of transformation described in the presented list. 2 A transformation is regarded as Add element when a sketch displays an element that is not present in the preceding sketch in the sequence. 2 In contrast to the other types of transformation in the list Change view does not represent a shape transformation of the design. 2 In general, design families can be identified by asking participants to describe the connections between sketches. At this stage of the analysis, the contribution of the participant is essential to avoid superficial and erroneous grouping of design based solely on researchers? perception. 2 In contrast to design families, shape transformations were more challenging to identify because during the interview process participants felt more fortable describing the connections between sketches and interpretation of their drawing than describing in detail the shape transformations they applied between their sketches. Instead the transformations identified were largely based on the interpretation of the researchers who were conducting the analysis. As a result, there is significant subjectivity in the transformations used to formalize the sketching processes of the participants. In order to examine the degree of this subjectivity two additional researchers were asked to analyze the transformations within five design families. Each researcher described the transformations of 40 sketch transformations and their results were then pared with the original analysis of the sketches. 2 This study has shown that given a limited number of shape rules it is possible to explicitly describe shape transformations between successive sketches. Shape rules offer a means to capture information not embedded in sketches which might be useful for the recording, reflection, and reuse of previous ideas. If such mechanisms could be realized it could also be possible to develop a more independent system that scrutinizes designers? freehand drawing, seeking to offer potentially valuable transformations. 3 In order to develop such mechanisms it is necessary to consider not only the technical issues of recognizing and manipulating perceived structures in a design but also the modes in which they could be implemented in a putational system intended to support design exploration. 3 Our future research plans are to involve designers in the process of describing their shape transformations with rules, and investigate potential benefits of putational systems that support explorative process through generation of design works. 。 Lewy et al., 1998。Landscape and Urban Planning(第一本 ) ABSTRACT This paper traces evidence of the influence of the landscape on people?s health, from ancient times to the present day, noting how access to nature and attractive green spaces has been a recurring theme in descriptions of therapeutic environments and associated healthy li
