We will implement large virtual spaces dynamic saccadic redirection methods for 2 person Redirected Walking (RW) in real room/multi-room scaling XR. Well use target numerical simulations & user scenario test data to evaluate XR performance metrics against TRL-4 goals. RW can deliver up to 10x real space walkable area in virtual space without 1 user awareness of real space. Our goal is to achieve best virtual vs. real space expansion with 2 users in same room. We will show hyperrealistic large virtual environments rendering with high level of terrain details appropriate for surface operations & object models such as instruments, tools, vehicles, & structures. Photorealistic accurate scenarios improve full immersion sensations & training outcomes. We will demonstrate accurate finger, hand, & object tracking for 2 rooms including tracking objects with limited visibility for typical astronaut activities, e.g., unload, transport, assemble. We will explore novel human-computer interface methods, such as gesture commands, next step scenario guided choice/presentation from eye, hand, finger motions, etc. to determine applicability for Phase I & Phase II R&D. UX interfaces in XR can guide users, follow responses to AR visual cues, present checklists, measure appropriateness of response & use trainee or user responses to guide next step training or operations to improve memory & new eye hand coordination retention during training, operational planning, & operational management. Our Deliverables include a theoretical framework implemented in hardware that demonstrate basic functionality & critical test environments, with key software components integrated & functionally validated to establish interoperability, with documented test performance demonstrating agreement with analytical predictions. Our (TRL-4) goal is to show breadboard systems with novel RW algorithms in a basic operating environment. All deliverables will be shown in a 2 person hands-on demo in XR. Potential NASA Applications (Limit 1500 characters, approximately 150 words): XR technologies can facilitate many missions, including those related to human space exploration, for planning, training, & operations support as well as for modeling & simulation of future orbital, transportation, & stationary structures for robotic & human use. The Human Exploration & Operations Mission Directorate, Space Technology Mission Directorate, Science Mission Directorate, Artemis, & Gateway programs could benefit from this technology. The crosscutting nature of XR technologies allows it to support all of NASAs Directorates. Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words): More realistic training environments deliver better training outcomes due to improved muscle memory. Commercial applications include training of pilots for aerospace; workplace injury reduction among construction, freight, material movers (2.8 million 2019); tele-robotics; surgical training; strength training; telepresence; education; gaming & entertainment.
