Presentation Transcript

  1. Visuomotor and Orientation Investigations in Long-Duration Astronauts • VOILA investigations utilize the Human Research Facility Workstation-2 and a suite of PI developed EUE to conduct: • E085/Human Orientation and Sensory-Motor Coordination in Prolonged Weightlessness • CM Oman, AM Liu (MIT) • E507/Spatial Orientation and Sensorimotor Coordination in Prolonged Weightlessness • A Berthoz, J McIntyre (CNRS-College de France)

  2. Science and Hardware Milestones 1993 NIH-NIDCD and ESA peer reviews of US (E136) and French (E111) Neurolab experiments 1995 JSC IPDL begins development of first generation VEG for shuttle and ISS. • NASA peer review of E085/”Human Orientation and Sensory-Motor Coordination”, a joint US/French ISS proposal for combined ISS experiments using HRF workstation as science kiosk (NRA-96-OLMSA-01). • CNES/ESA peer review of joint French/US proposal E507/”Spatial Orientation and Sensorimotor Coordination in Prolonged Weightlessness”. (NASA 96-HEDS-04). 1998 STS-90 Neurolab – VEG workstation flies without head tracker. 1999 E085/E507 ERR; E085 + E507 = “VOILA”; MIT-CSR selected to develop Virtual Reality EUE for HRF R2WS; Definition phase begins 2001 VOILA Hardware PDR

  3. Relevance • Protocols are targeted to high priority issues on NASA’s Bioastronautics Critical Path Roadmap: • Vertigo, disorientation, and spatial illusions • Impaired movement coordination following G transitions • “Ineffective habitats” • Mismatch between cognitive capabilities and task demands • CRL3-4 research leading to countermeasure deliverables: • Improved interior layouts, visual cues and procedures to reduce disorientation, navigation and reaching errors. • Improved tele-operation and preflight orientation training. • Risk characterization and scientific knowledge

  4. Disorientation and reference frames • 0- gravity, ambiguous visual cues, and unfamiliar orientations cause reference frame perception problems: • Visual Reorientation Illusions (VRIs; a.k.a. the “downs”) • Inversion illusions • Space motion sickness (FD0-5) • Object recognition difficulties • EVA height vertigo • “Getting lost” aboard Mir, ISS • Tele-operation reference frame integration difficulties

  5. E085 Scientific Questions • Visual reorientation illusions (VRIs) • Does susceptibility change during long duration flight ? • Can VRIs be reduced by providing haptic “pseudo-gravity” ? • What is the relative importance of visual symmetry and polarity cues and orientation of the viewer’s body axis ? • Visual self-motion illusions (“linearvection”, “circularvection”) • Does susceptibility decrease during long duration flight ? • Object recognition and shape-from-shading perception • Does dependence on subjective vertical change during long duration flight ?
