With limited human attention capacity, increased visual complexity in the near domain may lead to interference in the effective processing of information in the far domain. <\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p> Near-domain and far-domain vision were separately tested using a dual-task paradigm. In a simulated road environment, 62 participants were to control the speed of the vehicle (SMT; near domain) and manually respond to probes (PDT; far domain) simultaneously. Five HUD complexity levels including a HUD-absent condition were presented block-wise. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Near domain performance was not modulated by the HUD complexity levels. However, the far domain detection accuracies were impaired as the HUD complexity level increased, with greater accuracy differences observed between central and peripheral probes. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> Increased HUD visual complexity leads to a biased deployment of driver attention toward the central visual field. Therefore, the formulation of HUD designs must be preceded by an in-depth investigation of the dynamics of human cognition. <\/jats:p><\/jats:sec><jats:sec><jats:title>Application<\/jats:title><jats:p> To ensure driving safety, HUD designs should be rendered with minimal visual complexity by incorporating only essential information relevant to driving and removing driving-irrelevant or additional visual details. <\/jats:p><\/jats:sec>","DOI":"10.1177\/00187208231181496","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T07:22:35Z","timestamp":1686208955000},"page":"1879-1892","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Visual Complexity of Head-Up Display in Automobiles Modulates Attentional Tunneling"],"prefix":"10.1177","volume":"66","author":[{"given":"Jieun","family":"Lee","sequence":"first","affiliation":[{"name":"School of Psychology, Korea University, Seoul, Korea"}]},{"given":"Nahyun","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Psychology, Korea University, Seoul, Korea"}]},{"given":"Jangkyu","family":"Ju","sequence":"additional","affiliation":[{"name":"School of Psychology, Korea University, Seoul, Korea"}]},{"given":"Jihwan","family":"Chae","sequence":"additional","affiliation":[{"name":"School of Psychology, Korea University, Seoul, Korea"}]},{"given":"Jiyoon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Artificial Intelligence, Korea University, Seoul, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9515-4402","authenticated-orcid":false,"given":"Hoe Sung","family":"Ryu","sequence":"additional","affiliation":[{"name":"Department of Artificial Intelligence, Korea University, Seoul, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8481-3740","authenticated-orcid":false,"given":"Yang Seok","family":"Cho","sequence":"additional","affiliation":[{"name":"School of Psychology, Korea University, Seoul, Korea"}]}],"member":"179","published-online":{"date-parts":[[2023,6,8]]},"reference":[{"key":"bibr1-00187208231181496","doi-asserted-by":"publisher","DOI":"10.1037\/10037-000"},{"key":"bibr2-00187208231181496","first-page":"5","volume":"28","author":"Burnett G.
