Positive Experiences As Countermeasures To Stress In Spaceflight: An Investigation Of The Experiences Of Astronauts, Morgan M. Eudy
Positive Experiences As Countermeasures To Stress In Spaceflight: An Investigation Of The Experiences Of Astronauts, Morgan M. Eudy
Theses and Dissertations
Long-duration space mission targets such as asteroids, the Moon and Mars in coming years will increase the need to stress management techniques to support crews on increasingly risky, autonomous missions. New stress management approaches may be found by better understanding the reported positive effects resulting from factors in these environments. This study utilized an exploratory case study approach to leverage quantitative and qualitative data to yield research questions for future correlational analysis. This study found that positive experiences and changes in environmental perspectives occurred from viewing Earth from orbit. Furthermore, this study found that personality factors such as extraversion may …
Evaluation Of Low Cost Controllers For Mobile Based Virtual Reality Headsets, Summer Lindsey
Evaluation Of Low Cost Controllers For Mobile Based Virtual Reality Headsets, Summer Lindsey
Theses and Dissertations
Virtual Reality (VR) is no longer just for training purposes. The consumer VR market has become a large part of the VR world and is growing at a rapid pace. In spite of this growth, there is no standard controller for VR. This study evaluated three different controllers: a gamepad, the Leap Motion, and a touchpad as means of interacting with a virtual environment (VE). There were 23 participants that performed a matching task while wearing a Samsung Gear VR mobile based VR headset. Measures of performance, preference, presence, and enjoyment were collected and compared across controller. Overall, it was …
Architecture, Design, And Implementation Of A Rapidly Prototyped Virtual Environment For A Military Spaceplane, Scott A. Rothermel
Architecture, Design, And Implementation Of A Rapidly Prototyped Virtual Environment For A Military Spaceplane, Scott A. Rothermel
Theses and Dissertations
The new Global Engagement vision places increased emphasis on the Air Force's ability to control and exploit space. A military spaceplane combining reliable access to space, high operational tempos, and multi-mission capabilities is in conceptual stages of development. Virtual environment technology provides an opportunity to investigate system requirements and unconventional interface paradigms for this unique vehicle. A virtual environment architecture and design based on support for a rapid prototyping development process, separation of concerns, and user interface development is presented. The rapid prototyping process allowed management of changing requirements via an evolutionary approach to implementation. Separation of the activities performed …
Requirements, Design, And Development Of A Rapidly Reconfigurable, Photo-Realistic, Virtual Cockpit Prototype, Terry A. Adams
Requirements, Design, And Development Of A Rapidly Reconfigurable, Photo-Realistic, Virtual Cockpit Prototype, Terry A. Adams
Theses and Dissertations
The United States Air Force uses aircraft flight simulators for pilot training and mission rehearsal. They use a variety of simulators for this task ranging with prices ranging from $400,000 to $30,000,000. These simulators have specialized hardware that restricts reuse of their components and increases maintenance costs. Air Education and Training Command wants to reduce simulators cost and improve availability to the operational commands by supporting research in virtual reality flight simulators. This thesis looks at the development of a reconfigurable virtual cockpit in a distributed virtual environment that can be used for different aircraft as well as training scenarios. …
The Photo-Realistic Afit Virtual Cockpit, Milton E. Diaz
The Photo-Realistic Afit Virtual Cockpit, Milton E. Diaz
Theses and Dissertations
The Air Force Institute of Technology (AFIT) has pursued research in virtual environments since 1988. This research expands the current capabilities of the AFIT Virtual Cockpit (VC) by increasing the realism of the cockpit environment and improving the pilot's command interface. Realism is improved creating console elements from texture maps and polygonal models; these elements include working dials, switches and circuit breakers. The pilot command interface is improved in part by adapting the AFIT Information Pod using a two-dimensional mouse input to the virtual three-dimensional environment. This immersive virtual environment is also improved by modifications to the Head Mounted Display …
Rendering The Out-The-Window View For The Afit Virtual Cockpit, W. Dean Mccarty
Rendering The Out-The-Window View For The Afit Virtual Cockpit, W. Dean Mccarty
Theses and Dissertations
The Air Force Institute of Technology (AFIT) is developing a distributed interactive flight simulator, the Virtual Cockpit, using commercial graphics workstations and helmet mounted displays. The Virtual Cockpit communicates with other simulators via local and long-haul networks using the SIMNET protocol. The work reported in this thesis focuses on developing the terrain database for the synthetic environment and on rendering the pilot's view of the database. There are many different file formats for describing 3- dimensional geometric polygonal objects. An analysis of three formats, AFIT GEOM, the Naval Postgraduate School (NPS) DRP, and Software Systems' Flight, is presented. Each file …
A Synthetic Environment Flight Simulator: The Afit Virtual Cockpit, John C. Switzer
A Synthetic Environment Flight Simulator: The Afit Virtual Cockpit, John C. Switzer
Theses and Dissertations
This thesis describes the design and implementation of a part of the Virtual Cockpit: a synthetic environment, distributed network flight simulator. The goal of the project was to prove the concept that this type of flight simulator could fill the gap between high-end, very expensive flight simulators and low-end game quality flight simulators. Discussed are: object-oriented design techniques, multi-processor utilization, the flight dynamics model, synthetic environment technology, the frame-rate vs. realism issue, and the interfaces to a realistic joystick and throttle.
