Abstract: Environmental experience draws more and more attention these days, however accurate description and measurement remain tough. This study presents a new visual and comprehensive experience evaluation method based on real time and in-situ psychophysical feedback data and its application in planning and design evaluation. In this study, the physical and psychological feedback and spatial position movement of the human experience were collected by portable biofeedback and GPS devices and processed to make experience prediction using affective computing technology. By integrating the emotional data and the spatial data, with the in-situ and real time visual experience of the built environment evaluated, the environmental factors that stimulate the negative experience can be identified and specific improving strategy could be produced.
