Perception and evaluation of cleanliness in cities II

The aim of the project study is to validate the subjective findings, obtained in the first study, by objective parameters. Two further studies were carried out:
1. Laboratory study: The aim of the study is the validation of criteria concerning cleanliness by using physiological data (fixation and eye movement paths). Thus, the previously subjectively determined weighting of the criteria of cleanliness impression be objectified.
2. Field Study: The aim of the study is to validate cleanliness criteria via eye movement data in real city scenarios with high-definition eye movement measurement technology. Hereby, a review of previous findings and conclusions made under ecologically valid conditions is carried out.
