Abstract The full-chain system performance characterization is very important for the optimization design of an integral imaging three-dimensional (3D) display system. In this paper, the acquisition and display processes of 3D scene will be treated as a complete light field information transmission process. The full-chain performance characterization model of an integral imaging 3D display system is established, which uses the 3D voxel, the image depth, and the field of view of the reconstructed images as the 3D display quality evaluation indicators. Unlike most of the previous research results using the ideal integral imaging model, the proposed full-chain performance characterization model considering the diffraction effect and optical aberration of the microlens array, the sampling effect of the detector, 3D image data scaling, and the human visual system, can accurately describe the actual 3D light field transmission and convergence characteristics. The relationships between key parameters of an integral imaging 3D display system and the 3D display quality evaluation indicators are analyzed and discussed by the simulation experiment. The results will be helpful for the optimization design of a high-quality integral imaging 3D display system.

This study was conducted out of the researcher’s teaching reflection while teaching English as a foreign language (EFL) online class during the pandemic of COVID-19, a time when face-to-face courses had to be converted to online classes. Her choice of educational tool for her EFL e-learning environment utilized a Facebook closed group. Her experiences in utilizing a Facebook closed group for her EFL e-learning environment and the students’ views were the main topics of this study. Eighteen EFL freshmen participants were selected in this study. The researcher used data from a questionnaire with some closed and open-ended questions. The findings indicated that the students found the Facebook closed group a comfortable, practical, and useful e-learning environment. The students’ familiarity with the interface helped them to immediately focus on the class activities instead of learning how to use the tool. Most students viewed the Facebook closed group as positive for class interactions, creative work, opinions, and express feelings. A few dislike voices were related to the display quality of Facebook, the asynchronous and silent communication on Facebook. Accordingly, utilizing a Facebook closed group might be worth considering for learners who have not been adequately prepared with the technology for joining an online class.

Speed And Accuracy

Purpose This study aims to investigate “immersive reading,” which occurs when individuals read text while in a virtual reality (VR) or augmented reality (AR) environment. Design/methodology/approach In Experiment 1, 64 participants read text passages and answered multiple-choice questions in VR and AR head-mounted displays (HMDs) compared with doing the same task on liquid crystal display (LCD). In Experiment 2, 31 participants performed the same reading tasks but with two VR HMDs of different display quality. Findings Compared with reading on LCD as the baseline, participants reading in VR and AR HMDs got 82% (VR) and 88% (AR) of the information accurately. Participants tended to respond more accurately and faster, though not statistically significant, with the VR HMD of higher pixel density in the speed-reading task. Originality/value The authors observed the speed and accuracy of reading in VR and AR environments, compared with the reading speed and accuracy on an LCD monitor. The authors also compared the reading performance on two VR HMDs that differed in display quality but were otherwise similar in every way.
