Marta Rusnak, Marta Szmigiel, Malwina Geniusz, Zofia Koszewicz, Monika Magdziak-Tokłowicz, Exploring the impact of cultural context on eye-tracking studies of architectural monuments in selected European cities: Sustainable heritage management.
PublikacjaSustainable management of architectural heritage requires conducting an inclusive diagnosis of users' opinions, considering both residents and tourists as the recipients of urban space. Given the cultural diversity within these groups, proposing the use of eye-trackers (ET) as an alternative to traditional public consultation prompts the need to assess the method's advantages and disadvantages. It remains uncertain whether individuals...
