A Novel Algebraic Inverse Kinematics Based Approach to Gaze Control in Humanoid Robots
IEEE Access, 2023 The vision system of humanoid robots is one of the essential components that allow them to do complex activities. This has led to numerous studies on artificial gaze stabilization, many of which are based on biological vision system reflexes.

Columnar neurons support saccadic bar tracking in Drosophila
eLife, 2023 Tracking visual objects while maintaining stable gaze is complicated by the different computational requirements for figure-ground discrimination, and the distinct behaviors that these computations coordinate.

Gaze stability for liveness detection [PDF]
Pattern Analysis and Applications, 2016 Spoofing attacks on biometric systems are one of the major impediments to their use for secure unattended applications. This paper explores features for face liveness detection based on tracking the gaze of the user. In the proposed approach, a visual stimulus is placed on the display screen, at apparently random locations, which the user is required ...

Stabilizing gaze in flying blowflies [PDF]
Nature, 1998 When the gaze is moved quickly, vision becomes blurred and the way in which three-dimensional structures are seen can be affected1. How can these effects be minimized? During flight, blowflies (Calliphora vicina) turn both the head and the thorax very quickly, producing gaze shifts which affect vision.

Editorial: Gaze and postural stability rehabilitation
Frontiers in Neurology, 2022 Proprioceptive, Visual, Vestibular, and Cognitive systems interact in a continuous sensorial re-weighting, ensuring gaze and postural control (1, 2). The central nervous system integrates the information originating from these systems into a continuous sensorial re-weighting that ensures postural control in both static and dynamic conditions (3, 4 ...

Integration of visual and antennal mechanosensory feedback during head stabilization in hawkmoths
eLife, 2022 During flight maneuvers, insects exhibit compensatory head movements which are essential for stabilizing the visual field on their retina, reducing motion blur, and supporting visual self-motion estimation.

Conserved subcortical processing in visuo-vestibular gaze control
Nature Communications, 2022 Here, the authors show that gaze stabilization relies on a visuo-vestibular network conserved from lamprey to primates. This primordial blueprint highlights how visual and vestibular streams are organized to control fundamental aspects of eye movements.

Retinal motion statistics during natural locomotion
eLife, 2023 Walking through an environment generates retinal motion, which humans rely on to perform a variety of visual tasks. Retinal motion patterns are determined by an interconnected set of factors, including gaze location, gaze stabilization, the structure of ...

Saccadic dysfunction in patients with hypoxic-ischemic encephalopathy [PDF]
Journal of Integrative Neuroscience, 2018 Electrophysiological monitoring of saccadic eye movements in patients with hypoxic-ischemic encephalopathy was carried out. Externally guided saccades (prosaccades) were recorded using a patented hardware-software complex for studying a subject's ...
