Visitors in a space learn to "read" an area by using three- and two-dimensional cues. This research aimed to determine the responses of visitors to the influence of geometry on the legibility at Kuala Lumpur City Center (KLCC). The relationship between geometry and space legibility can affect visitors' wayfinding. In this study, visitors, including 86 respondents and 8 individuals who participated in a focus group, were surveyed through questionnaires and interviews during daytime. Results show that legibility was moderately and positively correlated with regular geometry, but legibility was negligibly affected by existing geometry. Regression analysis, Hest, ANOVA, and scheme coding of qualitative data suggested that regular geometry used in urban spaces might strongly improve legibility. For urban designers, regular geometry associated with landmarks enhances legibility.展开更多

The authors designed six backpacker hostels between 2013 and 2015, and of these, four are presently in operation. Hostels are the main infrastructures within the global network of backpacker tourism. Results from the design process revealed that the creation and operation of hostels are significantly influenced by three issues, namely, informality, density, and adaptability. These issues are negotiated on three interconnected tevels: the city, the building, and the interior. The authors developed an experimental structure for dormitory spaces as a conscious reaction to these issues. This experimental structure is presented and evaluated, and further paths of development are formulated based on the results.展开更多
