“…Therefore, our results suggest that guidelines established in the aerospace domain, specifying that so-called conformal guidance cues and symbology, where spatial overlays are matched to the real world and stay aligned even when moving, can be extended to the specific lunar context [81,90,133,134].…”

Future crewed missions to the Moon will face significant environmental and operational challenges, posing risks to the safety and performance of astronauts navigating its inhospitable surface. Whilst head-up displays (HUDs) have proven effective in providing intuitive navigational support on Earth, the design of novel humanspaceflight solutions typically relies on costly and time-consuming analogue deployments, leaving the potential use of lunar HUDs largely under-explored. This paper explores an alternative approach by simulating navigational HUD concepts in a high-fidelity Virtual Reality (VR) representation of the lunar environment. In evaluating these concepts with astronauts and other aerospace experts (n=25), our mixed methods study demonstrates the efficacy of simulated analogues in facilitating rapid design assessments of early-stage HUD solutions. We illustrate this by elaborating key design challenges and guidelines for future lunar HUDs. In reflecting on the limitations of our approach, we propose directions for future design exploration of human-machine interfaces for the Moon.

“…Conformal symbology is difficult to implement because the position of the head must be measured and the symbology updated quickly to mimic the shift in scene with changes in head position that occurs in the real world. Temporal lags in the measurement of head position impair human performance and create disorientation and discomfort because lags delay the update of imagery relative to the head movement (Long & Wickens, 1994;Velger, 1998) and produce a mismatch between proprioception (sense of body position) and vision. Such a situation exists when the HMD displays information that substitutes for the real-world view (Ineson, 1991;Kaye et al, 1990;Adam, 1994;Swenson et al, 1994), such as when simulating OTW viewing for training or mission rehearsal purposes.…”

SPONSOR/MONITOR'S ACRONYM(S)AFRL; AFRL/HEA SPONSOR/MONITOR'S REPORT NUMBER(S)Air ABSTRACTThis report provides a review and analysis of the published literature on head-mounted displays (HMDs). In particular, we discuss several key perceptual issues that are relevant to the use of HMDs. The issues discussed are: (1) brightness and contrast; (2) accommodationvergence synergy; (3) field of view; (4) binocular input; and (5) head movements. This review of the literature is intended to anticipate and solve perceptual issues associated with two particular HMD applications: (1) simulation of off-bore sight (OBS) targeting and (2) full fieldof-view out-the-window (OTW) simulation for deployable flight training. Additionally, several technology issues important to the continued development of HMDs are discussed. This report concludes with a set of recommendations for the design and use of HMDs for OBS and OTW flight training applications.
