This action research study has two aims: (i) to develop a wearable virtual reality language-learning platform for English for specific purposes and (ii) to examine student learning effectiveness and the relationship between self-efficacy and behavioral intention. The participants are 131 university students in Taiwan. A model of wearable virtual reality language-learning based on structural equation modeling is built. A path analysis indicates that self-efficacy directly influences students' perceptions of ease of use of the wearable virtual reality technology and indirectly influences perceived usefulness, attitude, and behavioral intention. Student self-efficacy is slightly above the moderate level. Gender and English proficiency have an effect on student self-efficacy and behavioral intention, whereas students' online and virtual reality learning experiences have no significant effect on these variables. This new environment is shown to facilitate student learning: the pretest and posttest results indicate improvements in lexical and semantic knowledge, reading comprehension, and syntax. The study implies that since self-efficacy is a crucial determinant in student technology use, educators should enhance student self-efficacy in order to encourage them to try innovative technology., Author(s): Chun-Chia Hsu [sup.1] , Yu-Li Chen [sup.2] , Chih-Yung Lin [sup.1] , Wei-chih Lien [sup.2] Author Affiliations: (1) grid.445089.4, 0000 0004 0639 3159, Department of Multimedia and Game Science, [...]

A driving simulator was used to examine the effects on driving performance of auditory cues in an in-vehicle information search task. Drivers' distraction by the search tasks was measured on a peripheral detection task. The difficulty of the search task was systematically varied to test the distraction caused by a quantified visual load. 58 participants completed the task. Performance on both search tasks and peripheral detection tasks was measured by mean response time and percent error. Analyses indicated that in-vehicle information search performance can be severely degraded when a target is located within a group of diverse distractors. Inclusion of an auditory cue in the visual search increased the mean response time as a result of a change in modality from auditory to visual. Inclusion of such an auditory cue seemed to influence distraction as measured by performance on the peripheral detection task; accuracy was lower when auditory cues were provided, and responses were slower when no auditory cues were provided. Distraction by the auditory cue varied according to the difficulty of the search task. DOI 10.2466/03.13.20.24.26.PMS.111.5.503-516

We have set up a wide-viewing-zone light field display with low crosstalk by simply using projectors and a diffusion screen, and we also figure out a method to define the perceptual depth for human with subjective experiment. [ABSTRACT FROM AUTHOR]
