Yet, there is lack of knowledge how people perceive and accept power lines in certain landscape types and in combination with wind turbines, a required setting to achieve goals of the energy turnaround. The goal of this work was to demonstrate how 3D point cloud visualizations could be used for an eye tracking study to systematically investigate the perception of landscape scenarios with power lines. 3D visualizations of near-natural and urban landscapes were prepared based on data from airborne and terrestrial laser scanning. These scenes were altered with varying amounts of the respective infrastructure, and they provided the stimuli in a laboratory experiment with 49 participants. Eye tracking and questionnaires served for measuring the participants\u2019 responses. The results show that the point cloud-based simulations offered suitable stimuli for the eye tracking study. Particularly for the analysis of guided perceptions, the approach fostered an understanding of disturbing landscape elements. A comparative in situ eye tracking study is recommended to further evaluate the quality of the point cloud simulations, whether they produce similar responses as in the real world.<\/jats:p>","DOI":"10.3390\/mti3020040","type":"journal-article","created":{"date-parts":[[2019,6,5]],"date-time":"2019-06-05T09:37:58Z","timestamp":1559727478000},"page":"40","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["3D Point Clouds and Eye Tracking for Investigating the Perception and Acceptance of Power Lines in Different Landscapes"],"prefix":"10.3390","volume":"3","author":[{"given":"Ulrike","family":"Wissen Hayek","sequence":"first","affiliation":[{"name":"Planning of Landscape and Urban Systems (PLUS), IRL, ETH Z\u00fcrich, 8093 Z\u00fcrich, Switzerland"}]},{"given":"Kilian","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Planning of Landscape and Urban Systems (PLUS), IRL, ETH Z\u00fcrich, 8093 Z\u00fcrich, Switzerland"}]},{"given":"Fabian","family":"G\u00f6bel","sequence":"additional","affiliation":[{"name":"Geoinformation Engineering, IKG, ETH Z\u00fcrich, 8093 Z\u00fcrich, Switzerland"}]},{"given":"Peter","family":"Kiefer","sequence":"additional","affiliation":[{"name":"Geoinformation Engineering, IKG, ETH Z\u00fcrich, 8093 Z\u00fcrich, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0943-779X","authenticated-orcid":false,"given":"Reto","family":"Spielhofer","sequence":"additional","affiliation":[{"name":"Planning of Landscape and Urban Systems (PLUS), IRL, ETH Z\u00fcrich, 8093 Z\u00fcrich, Switzerland"}]},{"given":"Adrienne","family":"Gr\u00eat-Regamey","sequence":"additional","affiliation":[{"name":"Planning of Landscape and Urban Systems (PLUS), IRL, ETH Z\u00fcrich, 8093 Z\u00fcrich, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2019,6,4]]},"reference":[{"key":"ref_1","unstructured":"Apostol, D., Palmer, J., Pasqualetti, M., Smardon, R., and Sullivan, R.
