With the growth of technical capabilities of virtual reality headsets, more headsets are receiving XR mode using cameras to display the surrounding world (Apple Vision Pro, Meta Quest 3, VIVE XR Elite). These headsets are positioned as a full-fledged alternative to headsets with hologram on transparent lens, such as Microsoft Hololens 2. Meanwhile, one of the reasons holding back the rapid rise in popularity of XR is the motion sickness that occurs when using VR/XR headsets. In this study, we experimented to determine which of the two approaches (camera+screen or hologram on transparent lens) has less motion sickness and which solution can be considered more promising for XR exploration in the future. As a result, our research shows that hologram on transparent lens has much less motion sickness in the current stage of technical progress. Still, its issues need to be solved to provide a non-motion sickness experience to the user.
