ABSTRACT

This article intends to fulfill two objectives: on one hand, to present the technology of ‘portable eye tracking’ as an effectihve way of studying vision analytically and especially with regard to three-dimensional immersive practice (which other eye tracker models do not allow); on the other hand, taking as basis a study (Alão 2017) carried out in Lisbon between 2014 and 2016, it pretends to show the limitations of this equipment, pointing out the only way that seems trustworthy to work with it, in order to obtain results with scientific value. It’s also points towards future resolutions. 120 analyses of three-dimensional architectural space were performed by 30 observers in 4 different architectural locations, with the use of portable eye tracking technology, featuring 120 samples. Thereafter, 60,000 video frames were analyzed to better understand the types of elements we have to read visual information.
