“…Therefore, there is actually a range of C values, [3=2s 0 , 2=s 0 ], that would satisfy these lemmas; however, condition (5) can be satisfied only by equation (8). Hermite scaling can be realized by using only any two parameters from among s 0 , s 1 , x 1 , and L, but x 1 and L are usually selected.…”

“…This requires years of training by astronauts to perfect the precision and stability in the flight of high gain input to perform a safe landing. 8,9 During the spacecraft return phase, specifically, during re-entry, acceleration and angular velocity signals can vary considerably over short time periods. That means the method of TOPS cannot meet the requirements of return phase simulation.…”

Signal scaling is an essential step in spaceflight simulation. Thus far, the third-order polynomial scaling method has been widely used for signal scaling; however, in this method, parameter tuning is complicated and may induce perceptible distortion during large-range monotonic signal scaling. In the simulation of spacecraft return, specifically, that of re-entry, acceleration and angular velocity signals may vary considerably over short time periods. Motion perception is important for training astronauts in this phase. In this study, two strategies are proposed to solve these problems using the 'scaling scope' parameter. The first strategy is based on the Hermite interpolation polynomial, and the other is based on thirdorder polynomial scaling. Two methods were developed which make use of the stable region of third-order polynomial scaling. The first method maximizes the stable region to prevent signal distortion, and the other restricts the scaling scope in the stable region. Based on the dynamic characteristics of spacecraft in the return phase, the signal scaling strategies proposed in this study are simulated for trainees' perception in a motion-base simulator. Simulations were implemented by utilizing the full curves of spacecraft return phase for the first time, and results show that these methods are more advantageous for parameter tuning and can eliminate signal distortion for all input signals. While these methods have a shortcoming in that the trigger velocity (onset cue) is slowed down, this shortcoming is eliminated by employing the moving cueing algorithm. Both the strategies proposed in this article show good performance and can be applied potentially to the motion simulation of the spacecraft return phase.

“…6 The VMS has been primarily used as an R&D simulator, though it has been used for a combination of training and engineering studies during the NASA Shuttle program. 7 The VMS, shown in Fig. 1, is an uncoupled, six-degreeof-freedom motion simulator that moves within the confines of a hollow ten-story building.…”

There has been a significant effort within the simulation community to standardize many aspects of flight simulation. More recently, an effort has begun to develop a formal scenario definition language for aviation. A working group within the AIAA Modeling and Simulation Technical Committee has been created to develop a standard aviation scenario definition language, though much of the initial effort has been tailored to training simulators. Research and development (R&D) simulators, like the Vertical Motion Simulator (VMS), and training simulators have different missions and thus have different scenario requirements. The purpose of this paper is to highlight some of the unique tasks and scenario elements used at the VMS so they may be captured by scenario standardization efforts. The VMS most often performs handling qualities studies and transfer of training studies. Three representative handling qualities simulation studies and two transfer of training simulation studies are described in this paper. Unique scenario elements discussed in this paper include special out-the-window (OTW) targets and environmental conditions, motion system parameters, active inceptor parameters, and configurable vehicle math model parameters.

“…Technology, including VR programs, has been introduced into both course curriculum and professional training applications since the 1990s. One of the earliest applications of VR for professional training was found in vertical motion simulation (VMS) training of shuttle astronauts (Beard et al, 2006). The VMS replaced traditional simulators and was used for the training of both shuttle astronauts and commercial pilots.…”

With the proliferation of students’ abilities to use technology, in particular virtual reality (VR) applications, teachers are experimenting with VR in virtual learning environments (VLE) to engage students; but clear ethics and safety guidelines are not available. Within the field of education additional research is needed to determine how VR is employed in VLEs. Additionally, what are the decision-making processes of educators for the VR programs chosen for classroom use based on ethics and student safety? Through qualitative inquiry, educators from K–12 and higher education shared their perceptions of ethics and safety concerns in VR applications for use in the classroom. We collected data from a sample of K–12 and higher education professionals from the Association for Educational Communications and Technology (AECT) membership, an educational organization emphasizing technology integration and learning. Data analysis from the individual interviews with open-ended questions revealed five primary themes and twelve sub-themes. Participants agreed that they need ethical and safety guidelines as they embark on new horizons that influence student well-being. The findings from this study may provide an in-depth understanding of the importance of developing ethics and safety guidelines for educational VR programs when used by students.
