The result is a delayed attribution of meaning to the acquired context of a si tuation.\n\nInstead of updating the flight model based on flight instrumen ts\, pilots tend to replace it with erroneous pre-LOC data or erroneous ex pectations (lack of awareness of being in LOC\, loss of sense of time).\n\ nVestibulo-oculomotor responses (VOR) are useful during ground operations. They ensure the stability of the image projection on the retina\, essenti al for high-spatial-frequency vision\, VOR moves the eyes at the same spee d as the head\, but in the opposite direction\, compensating for head move ment. This prevents the projected image from shifting and blurring\, which can impair high-resolution vision.\n\nThe VOR operates in opposition to h igh-resolution vision\, impairing it to the point\, that pilots may strugg le to properly read flight/navigation instruments.\n\nPre-flight testing i s necessary to assess reduced VOR habituation. The WHITE-BOX project postu lates monitoring the pilot's EYE MOVEMENTS during flight.\n\nCo-sponsored by: Poznan University of Technology\n\nSpeaker(s): Jan Ober\, \n\nRoom: ro om 230\, Bldg: CENTER FOR MECHATRONICS\, BIOMECHANICS\, AND NANOENGINEERIN G\, POZNAŃ UNIVERSITY OF TECHNOLOGY\, ul.
