Abstract: In the new stage of high-quality urban development, public space is of great significance in improving the quality of the human environment. From a humanistic perspective, there is growing attention on exploring how space is experienced by people and its complex relationships with environmental features. The new demand for the humanized and refined construction of public space has posed a new challenge to design modes based on traditional analytical tools (e.g., questionnaire research and field observations) as well as the relatively ambiguous and subjective experiences of designers.
　　New tools emerging from the fourth industrial revolution provide new perspectives and ways to study experiences of urban public space from a humanistic perspective. To offset challenges in traditional studies, digital technologies provide support on three levels: the description of experience characteristics, analysis of spatial correlation, and simulation of experience prediction. Accordingly, it enables more accurate and scientific experience measurements, a closer correlation analysis with spatial characteristics, and guides the implementation of space design schemes based on human-centered experiences.
　　A development history was reviewed using CiteSpace. Both Chinese and foreign digital technologies first focused on studies on behavioral experiences. Then, they were gradually employed in the field of perceptual experience, wherein considerable development occurred around 2018. Although studies on spatial behaviors and perception have attracted considerable research attention in the fields of urban and landscape design since the 20th Century, it is difficult to match perceptual experience, as psychological content, with physical space. However, the development of digital technology has built a bridge between perceptual experience and space, as well as supporting the spatial layout design of plane morphology and the perspective of façade. Based on the space experience process frame of "feeling-perception-cognition-behaviors", the research progress on spatial experiences in different stages based on digital technologies was reviewed, revealing the following themes: assisting in understanding of feeling experience, providing a characterization pathway for sensory stimuli; achieving the intelligent scale measurement of perceptual experiences and exploring driving factors of urban environment; supporting studies on cognitive emotions and preferences thereby achieving in-situ evaluation and characteristic extraction; achieving the spatiotemporal monitoring and analysis of behaviors and expanding studies on optimal behavioral solutions to simulation. There were some general development trends in research on space experience with the assistance of digital technology, such as the systematization of general coupling studies, refinement of technological measurement methods, diversification of space characteristic analysis, and dynamic experience studies. Finally, prospects were proposed from the perspectives of research objects, research contents, and internal mechanisms.
