A comparison study of stationary and mobile eye tracking on EXITs design in a wayfinding system

"Wayfinding system" is an interdisciplinary research between the environment design and human interface of information system. The design of EXIT is to efficiently help people to identify the emergency exit when the accident occurred. In this paper, eye tracking techniques are utilized to aided EXIT design in the wayfinding system. The mobile eye tracking was used to collect the human eye movement data in the building where different EXIT designs were displayed. While the stationary eye tracking techniques was used to collect the eye movement data on the same building's EXIT designs on virtual 3D sketches to get the quantitative data comparing with the mobile eye tracker. Finally, some general conclusions were obtained from the views of visual elements selecting, EXIT appearance design and EXIT's placement in the building, which is very valuable and can be commonly referred in wayfinding system. The research methods in the paper is very original and has not been mentioned in other papers of the related fields before, which is well worthy data and empirical methodologies can be introduced in wayfinding and space decision making research.
