Evaluation of a Virtual Environment Prototype for Studies on the Effectiveness of Technology-Based Safety Signs

摘要

This pilot study aimed to evaluate the viability of using a Virtual Environment (VE) prototype for conducting research regarding technology-based safety signs, i.e., Augmented Reality (AR) warnings. Using a complex work-related context (comprised of two hazardous situations with distinct salience levels) and a sample of 12 workers (27-60 years), the study's objectives were to assess: the AR safety signs' effectiveness in enhancing hazard-risk behaviors and promoting behavioral compliance; as well as the participants' overall user experience. To undergo such an evaluation, the following issues were addressed: simulator sickness; level of presence; hazard and safety sign perception; and overall usability. Results reveal that: the AR warnings were effective in identifying hazards and in prompting compliant behaviors; and despite slight simulator sickness, participants were highly engaged, as well as adequately perceived both hazards and warnings. Thus, the VE prototype proved to be adequate for safety sign research regarding AR warnings.
