Making Virtual Sense: Display Type and Narrative Medium Influence Sensemaking in Virtual Environments

摘要

Virtual reality (VR) is being used for training and research in various industries due to its greater immersion relative to flat screen simulation technology. However, the effect of immersive VR displays and background storylines (i.e., narrative) on metacognitive skills, such as sensemaking, remains unexplored. The current study employed a 2 × 2 between-subjects experimental design to investigate the influence of display type and narrative medium on sensemaking for an observation-based driving task. Sixty-eight adults were semi-randomly assigned to one of four conditions. Participants received a pre-mission narrative briefing (text or multimedia) and undertook two simulated driving missions (flat screen or VR display). A structured debriefing followed each mission to assess sensemaking in terms of frequency and type of explanation for mission events. The results indicate that both display type and narrative medium influence sensemaking in virtual environments. For explanations relating to previously encountered mission events, sensemaking frequency was higher in the VR conditions than the flat screen conditions (F(1) = 9.11, p =.004, partial η~2 = .15). For explanations relating to the briefing materials, sensemaking frequency was higher in the multimedia narrative conditions than the text-based narrative conditions (F(1) = 8.38, p = .005, partial η~2 = .14). Although the findings suggest that VR displays have cognitive benefits over traditional flat screen displays, the likelihood of VR-induced adverse effects (i.e., cybersickness) should be managed (e.g., limiting exposure). These results indicate that narrative medium and display type should be carefully considered by industries using virtual environments for training and research.
