The use of a commercial-off-the-shelf (COTS) head-mounted display (HMD) and its effects on simulator sickness (SS) was investigated in this preliminary study. Participants performed a navigation task and an observational task. Both of the tasks allowed participants to freely view the 360 degree dynamic three-dimensional (3D) virtual reality environment (VRE). We hypothesized that SS would increase over time participating in the VRE and that SS would be greater in the observational task as compared to the navigation task. SS ratings did increase over time; however, SS did not differ between the observational and navigation task. These findings suggested that SS is still a relevant factor to consider with COTS 3D HMD use.

Trainers need to identify effective, low-cost training experiences for today’s military workforce to meet the increasing demands of today’s warfighting environment. Although low-fidelity simulations have been demonstrated to be effective in this regard, research has demonstrated that specially tailored pre-experiences can increase the effectiveness of these simulations. Unfortunately, the cost of these pre-experiences negates the cost benefits of the simulations that they improve. In this article, we describe a study to evaluate the effectiveness of a lower cost pre-experience. The results are discussed in the context of future directions for research.
