A kinematic model for 3-D head-free gaze-shifts
Rotations of the line of sight are mainly implemented by coordinated motion of the eyes and head. Here, we propose a model for the kinematics of three-dimensional (3-D) head-unrestrained gaze-shifts. The model was designed to account for major principles in the known behavior, such as gaze accuracy, spatiotemporal coordination of saccades with vestibulo-ocular reflex (VOR), relative eye and hea...
متن کاملInfluence of Static Eye and Head Position on Tone-Evoked Gaze Shifts - Contribution of head to gaze shifts
To program eye-head gaze shifts to sounds, the orientation of eyes and head should be incorporated to specify the target relative to the eyes, and only head orientation should be incorporated to specify the target relative to the head. Here we test whether the eye and head motor systems employ different reference frames for gaze shifts evoked by broadband sounds and pure tones. The head-movemen...
متن کاملHuman eye-head gaze shifts in a distractor task. I. Truncated gaze shifts.
This study examines two current ideas regarding the control of eye-head gaze shifts. The first idea stems from recent studies involving electrical stimulation in the primate superior colliculus that suggest that a residual feedback of gaze displacement persists for approximately 100 ms after completion of a gaze shift. In light of this hypothesis, we examined the accuracy of gaze shifts generat...
متن کاملNoise minimization and equalization for Stokes polarimeters in the presence of signal-dependent Poisson shot noise.
We address the optimization of Stokes polarimeters in the presence of signal-dependent shot noise, which is the dominant type of noise in certain imaging systems. We show that in some precise sense, the polarimeters optimal for additive noise are also optimal for such noise and propose polarimeter architectures in which noise variances are equalized and independent of the input polarization state.
متن کاملEmotionally Expressive Head and Body Movement During Gaze Shifts
The current state of the art virtual characters fall far short of characters produced by skilled animators. One reason for this is that the physical behaviors of virtual characters do not express the emotions and attitudes of the character adequately. A key deficiency possessed by virtual characters is that their gaze behavior is not emotionally expressive. This paper describes work on expressi...
