This session will look into some of the latest tools planners and architects are using to assess the human experience of the built environment. Car and technology companies have long been using these tools to help market their products; now planners can use them to understand the human experience of the built environment and how human perception is relational, meant for one-on-one interaction. They can help to create safer and healthier places and spaces for people. This session will present studies using mobile eye-tracking and galvanic skin response (GSR) monitors to reveal how the nervous system acts subliminally, directing our behaviour without conscious awareness or control. Participants will gain understanding of essential human biology and learn how we can track and record hidden behaviours that lay the foundation for the experience of place.
