Understanding and modeling perceptual quality assessment is greatly enriched by insights from visual attention. However, incorporating aspects of visual attention in DPC quality models is largely unexplored, as ground-truth visual attention data are scarcely available. Besides, testing methods and procedures for collecting visual attention data are still to be agreed on. This article presents a dataset containing subjective opinion scores and visual attention maps of DPCs, collected in a VR environment using eye-tracking technology. Both the quality score and eye-tracking data were collected during a subjective quality assessment experiment, in which subjects were instructed to watch and rate DPCs at various degradation levels under 6 Degrees of Freedom (DoF) inspection, using a head-mounted display. Qualitative interview analysis was also conducted after the experiment. The dataset consists of 50 DPCs, including 5 reference DPCs, with each reference encoded at 3 distortion levels using 3 different codecs (namely G-PCC, V-PCC, CWI-PCL), amounting to a total of 9 degraded version per reference. Additionally, it incorporates 1,000 gaze trials from 40 participants, yielding a total of 15,000 visual attention maps across all the DPCs.<\/jats:p>\n          <jats:p>We additionally benchmark objective quality metrics originally designed for static point clouds, evaluating their performance in our dataset using two temporal pooling strategies. Furthermore, we employ the visual attention data that are retrieved during our experiment to evaluate whether the performance of widely used objective quality metrics is improved by considering subjective measurements of visual attention. This dataset establishes a link between quality assessment and visual attention within the context of DPC. Moreover, thematic analysis of the interviews helps uncover user behavior and factors impacting perceptual quality for DPC in 6 DoF. This work deepens our understanding of DPC quality assessment and visual attention, driving progress in the realm of VR experiences and perception.<\/jats:p>","DOI":"10.1145\/3731759","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T08:36:55Z","timestamp":1745483815000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Subjective and Objective Quality Assessment for Dynamic Point Cloud with Visual Attention in 6 DoF"],"prefix":"10.1145","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1967-596X","authenticated-orcid":false,"given":"Xuemei","family":"Zhou","sequence":"first","affiliation":[{"name":"Centrum Wiskunde &amp; Informatica, Amsterdam, TU Delft, Delft, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8990-2665","authenticated-orcid":false,"given":"Irene","family":"Viola","sequence":"additional","affiliation":[{"name":"Centrum Wiskunde &amp; Informatica, Amsterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5561-9711","authenticated-orcid":false,"given":"Evangelos","family":"Alexiou","sequence":"additional","affiliation":[{"name":"Xiaomi Technology, The Hague, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7006-2560","authenticated-orcid":false,"given":"Jack","family":"Jansen","sequence":"additional","affiliation":[{"name":"Centrum Wiskunde &amp; Informatica, Amsterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1752-6837","authenticated-orcid":false,"given":"Pablo","family":"Cesar","sequence":"additional","affiliation":[{"name":"Centrum Wiskunde &amp; Informatica, Amsterdam, TU Delft, Delft, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2025,8,12]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/PCS50896.2021.9477449"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/ICMEW46912.2020.9106005"},{"key":"e_1_3_2_4_2","doi-asserted-by":"crossref","first-page":"501","DOI":"10.1016\/B978-0-32-391755-1.00024-9","volume-title":"Immersive Video Technologies","author":"Alexiou Evangelos","year":"2023","unstructured":"Evangelos Alexiou, Yana Nehm\u00e9, Emin Zerman, Irene Viola, Guillaume Lavou\u00e9, Ali Ak, Aljosa Smolic, Patrick Le Callet, and Pablo Cesar. 2023.
