“…This study uses Unity particle systems and a texture shader to simulate liquid. Such a particle system has demonstrated good performance (30 FPS) on HoloLens (v1) Koenig et al (2021). Rather than doing an evaluation of LS performance on AR-HMDs, this paper examines the visual representation of LS via the Realism dimension, as described in detail in Section 4.…”

This paper presents a proof-of-concept Augmented Reality (AR) system known as “SMARTLab” for safety training in hazardous material science laboratories. The paper contains an overview of the design rationale, development, methodology, and user study. Participants of the user study were domain experts (i.e., actual lab users in a material science research department, n = 13), and the evaluation used a questionnaire and free-form interview responses. The participants undertook a virtual lab experiment, designed in collaboration with a domain expert. While using the AR environment, they were accompanied by a virtual assistant. The user study provides preliminary findings about the impact of multiple dimensions, such as Performance Expectancy, Emotional Reactivity, and Spatial Presence, on SMARTLab acceptance by analyzing their influence on the Behavioral Intention dimension. The findings indicate that users find the approach useful and that they would consider using such a system. Quantitative and qualitative analysis of the SMARTLab assessment data suggests that a) AR-based training is a potential solution for laboratory safety training without the risk of real-world hazards, b) realism remains an important property for some aspects such as fluid dynamics and experimental procedure, and c) use of a virtual assistant is welcome and provides no sense of discomfort or unease. Furthermore, the study recommends the use of AR assistance tools (a virtual assistant, an attention funnel, and an in-situ arrow) to improve usability and make the training experience more user-friendly.

“…AR can impose digital information in addition to real, physical surroundings, thus deepening the process of active learning [44]. According to Koenig et al [45], one open research challenge in designing mixed-reality technology-based training is how to replicate the training environment as closely as possible to the real world.…”

The Enhancement of OSH Training with an Augmented Reality-Based App

Recent advances in training approaches and technology have identified the need to improve training in the field of occupational safety and health (OSH). While many researchers have examined the use of augmented reality (AR) and technology-based classrooms to enhance conventional training practices, quantitative evidence for their effectiveness and motivational im-pact remains scarce. To contribute to filling this research gap, an AR-based application was developed to enhance OSH training. The enhanced training session was conducted in a closed, safe environment with ten participants with no background in OSH. Pre-test, post-test, and instructional material motivation surveys (IMMS) using a five-point Likert scale were deployed to measure the effectiveness and motivational impact in accordance with the respective ARCS factors. The empirical results obtained show that partici-pants performed significantly better in the post-tests than in the pre-tests (mean = 14.60, s = 1.71, t(9) = –12.11 with p-value < 0.001). The IMMS re-sults show that the perceived motivation arising from the AR-based applica-tion resulted in the highest mean score for the satisfaction factor (4.80) fol-lowed by the relevance (4.65), confidence (4.60), and attention (4.55) fac-tors. The results of the evaluation suggest that the AR-based application boosted participants’ active learning behavior, engagement, and interest dur-ing the enhanced training session and produced a better learning outcome and experience.
