Aims:
1. Evaluate modifications that permit use of our tablet-computer system in ambient lighting (current version requires darkness to eliminate binocular alignment cues).
2. Assess binocular alignment (vertical and torsional skew) in different g levels of parabolic flight.
3. Determine the nature of the function that relates the sensorimotor response of binocular alignment to instantaneous g level: continuous (with what slope) or piecewise-linear (with a threshold).

Description:
This task will provide information on binocular alignment as a measure of otolith asymmetry – more specifically as a measure of the neural compensation for asymmetry, which changes as a function of g level.
