Design of Digitally Reused Leftover Spaces Based on Spatial and Behavioural Interaction

Due to the rapid development of urban transport, the construction of viaducts has changed the spatial layout in the past and left some leftover spaces underneath the bridges that have not been properly utilised. At the same time, digital technology has been continuously applied to the analysis process of the design of the reuse of leftover space. However, the form-oriented approach to digital analysis and application in the design process of leftover spaces has neglected the analysis of the needs of people’s activities in the space, resulting in the restriction of people’s behaviour in interacting with the space, as well as the weakening of the natural perception and historical and cultural impression of the environment of the reused leftover space. This article focuses on strengthening the analysis of spatial-behavioural interactions in digital applications in the design process by incorporating theoretical approaches such as the behavioural signs method, the AEIOU method, and narrative design, to strengthen the analysis of the history, culture, and human needs of the leftover space in digital technology for the development of human-centred and sustainable design, and to link the historical significance of the leftover space closely with the contemporary people’s ways of activity, to solve the problem of the lack of digital analyses in the process of the design of the leftover space based on the habits of human behaviours and the spatial experience. Ultimately, the aim is to make the application of digital technology in the process of designing for the reuse of leftover space pay more attention to the interaction between people and space: how human behaviour affects the generation of space, to perpetuate and develop the past and contemporary value of space, and to further promote the development of the design practice of the reuse of leftover space in the direction of being more sustainable and more humane.
