(a) (b) (c) Figure 1: 2-D illustration of relationship between gaze direction and head pose. (a) Under a fixed head pose (r0, t0), gaze direction α can be estimated from appearance. (b) To obtain α under another head pose (r̂, t̂), the estimated α ′ should be corrected because of captured eye appearance distortion. (c) Under head pose (r̂, t̂), gaze direction under WCS should be further compensated...

1. Experiments were concerned with the long-term adaptive changes that occur in the primate vestibuloocular reflex (VOR) when the visual input associated with head movements is disturbed by various optical devices, including telescopic spectacles (magnification 2.0 and OS), fixed-field spectacles (field of view fixed with respect to the head; hence, equivalent here to “zero power” lenses), and ...

A methodology is developed to explicitly fuse sensor data from a combination of fixed and head-mounted sensors, in order to improve the registration of objects in an augmented reality system. The methodology was applied to the analysis of an actual experimental augmented reality system, incorporating an optical see-through head-mounted display, a head-mounted CCD camera, and a fixed optical tra...
