Subjective experience and visual attention to a historic building: A real-world eye-tracking study by De la Fuente Suárez, Luis Alfonso

“…Eye tracking allowed for the identification of the architectural elements that were objects of attention, the lengths of observation, and the points of view from which the elements were observed. Other data collection techniques, such as the think-aloud protocol and a special type of survey, were used to deeply understand the experiences that accompanied the visual exploration of the historic building. …”
