| Popis: | Virtual Reality-based Learning Environments (VRLEs) are an emerging tool for classroom teaching. While VRLEs are increasingly in use, little attention has been paid to ergonomic challenges in use of VRLEs. This study compared two 3D interface designs of a VRLE created to teach the phases of the Moon. Participants ( N = 16) were randomly assigned to either a Hand or Toggle interface design. The interface designs were compared in terms of postural risk (REBA score), task completion time, user experience and environmental presence. Results indicate no significant difference between the Hand and Toggle interface designs for the outcome variables; however, environmental presence was marginally higher in the Hand interface. REBA scores for Hand (3.56 ± 0.89) and Toggle (3.79 ± 1.14) indicate low to medium level of postural risks. Future research should focus on development of 3D interface design guidelines to ensure safe, comfortable and effective use of VRLEs. |
