Virtual reality holds significant potential for training applications, enabling users to access various training content easily, flexibly, and independently. However, the optimal approach for presenting training instructions and explanations within virtual reality remains an open question. Therefore, our research examines the effectiveness of different methods for transferring essential training information, such as instructions and explanations, to the user. In a study, we compared the following four information transfer modalities: 1) Audio (speech only), 2) Tablet (text-based information displayed on a tablet), 3) Mix (text on a tablet with supplementary speech), and 4) Overlay (text overlaid on the user's field of view). We conducted a within-subjects study as it yields more accurate results and allows the detection of weaker effects. Based on 44 participants, our findings demonstrate that the Mix method is significantly more effective compared to the three alternatives and is also rated as the preferred information transfer method. The knowledge gained from this research can be used to improve the effectiveness of future virtual reality training applications.
