Eye-tracking Virtual Reality System in Environmental Interaction Design

The work aims to study the environmental interaction design through powerful rendering and realistic interactive function of virtual reality and the eye-tracking virtual reality system. Trajectory chart and heat map provided by eye-tracking technology were applied in the interactive experiment of virtual reality environment to analyze the data and innovatively obtain the high-precision sensing information in the environmental interaction. Through the "environment-sensing-interaction" mode, long-term and full-coverage big data import and real-time recording of accurate spatial information and instant feelings, the design of environmental dimension and sensing dimension centered on multiple users was achieved. New technologies not only provide more intuitive expression and more objective analysis for researches, but also promote innovation in existing research paradigms. Eye-tracking virtual reality research enables the design to overall take into account the multiple variables and their interaction effects in the actually built environment, further to realize the transformation from observation after design to pre-judgment and correction in the design process, and consequently to strengthen the targeted and pre-positioned guidance of the design practice.
