We propose to address this problem with a probabilistic approach using Bayesian inference. The desired result of the inference is a predicted probability density function (PDF) specifying for each object in the scene a probability to be attended by the user. To evaluate the quality of a predicted attention PDF, we present a methodology to assess the information value (i.e., likelihood) in the predictions of different approaches that can be used to infer object attention. To this end, we propose an experiment based on a visual search task, which allows us to determine the object of attention at a certain point in time under controlled conditions. We perform this experiment with a wide range of static and dynamic visual scenes to obtain a ground-truth evaluation dataset, allowing us to assess GTOM techniques in a set of 30 particularly challenging cases.\n          <\/jats:p>","DOI":"10.1145\/2644812","type":"journal-article","created":{"date-parts":[[2014,9,17]],"date-time":"2014-09-17T14:22:25Z","timestamp":1410963745000},"page":"1-17","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["Gaze-to-Object Mapping during Visual Search in 3D Virtual Environments"],"prefix":"10.1145","volume":"11","author":[{"given":"Matthias","family":"Bernhard","sequence":"first","affiliation":[{"name":"Vienna University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Efstathios","family":"Stavrakis","sequence":"additional","affiliation":[{"name":"Cyprus Institute"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Hecher","sequence":"additional","affiliation":[{"name":"Vienna University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Wimmer","sequence":"additional","affiliation":[{"name":"Vienna University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2014,8,29]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1857893.1857897"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13414-012-0322-z"},{"key":"e_1_2_1_3_1","volume-title":"Eye Tracking Methodology: Theory and Practice","author":"Duchowski A.
