Eye and Head Displacement to Targets Fixated in the Vertical and Horizontal Planes

Abstract

While the nature of eye and head displacements t o target acquisitions i n the horizontal plane have been frequently studied, such investigations i n the vertical plane are somewhat scarce. In the experiment reported herein the f i n a l displacements of the head, eye, and gaze were examined for target acqdsitions i n the vertical and horizontal planes. The subjects' task was t o f i x a t e on a central target until receiving a verbal command to fixate on one of four peripheral targets. The analysis of the m e a n head, eye, and gaze displacement data t o the target vertical and horizontal planes. and MacAulay-Brown, Inc. (MacB) portions of t h i s effort were performed in support of the USAF AAMRL Contract Numbers F33615-85-C-0541, and F33615-82-C-0513, respectively.

What are the visuo-motor tendencies of omnidirectional scene free-viewing in virtual reality?

“…Head movements extend the field of view: saccades can be planned toward regions outside of it ( Guitton & Volle, 1987 ; Von Noorden & Campos, 2002 ). There is a preference for short eye rotations completed by head movements ( Janson et al., 1987 ; Malinov et al., 2000 ; Einhäuser et al., 2007 ; Freedman, 2008 ). The head accompanies the eyes, even during small gaze saccades ( Ritzmann 1875 ; Bizzi et al., 1972 ; Einhäuser et al., 2007 ; Hu et al., 2017 ).…”
