Abstract: In the digital age, human-computer interaction is constantly revolutionizing how we interact with our environment, allowing us to perceive landscape in an unprecedented way. In order to systematically clarify how human-computer interaction affects landscape perception, this research firstly analyzes the influence of human-computer interaction on the way people think and act and on people’s experience needs. Secondly, based on the acting media and mechanism of human-computer interaction, the research proposes the influence of human-computer interaction on landscape perception from the following four dimensions: expansion of the scope of spatial information through multi-source data (perception dimension); enhancement of multi-source data expanded through multi-channel interaction (perception mode); enhancement of dynamic response process through real-time calculation (perception process); triggering of emotion feedback through emotion calculation (perception effect). Finally, the research discusses the opportunities that human-computer interaction can bring for landscape perception in the future in the context of new information technology, new interaction mode, new intelligent feedback and new emotion trigger, to providing reference for the expansion and design innovation of the research direction of landscape architecture.
