Drawing from Memory: Hand-Eye Coordination at Multiple Scales

Drawing from Memory: Hand-Eye Coordination at Multiple Scales

Eyes move to gather visual information for the purpose of guiding behavior. This guidance takes the form of perceptual-motor interactions on short timescales for behaviors like locomotion and hand-eye coordination. More complex behaviors require perceptual-motor interactions on longer timescales mediated by memory, such as navigation, or designing and building artifacts. In the present study, t...

Eye–hand coordination: Eye to hand or hand to eye?

Single-unit recording has revealed both hand and eye movement-related activity in the parietal cortex of the macaque monkey. These experiments, as well as neuropsychological studies, are unravelling the complex nature of how the eye and the hand work together in the control of visually guided movements.

Uncalibrated Stereo Hand-Eye Coordination

This paper describes a system that combines stereo vision with a 5-DOF robotic manipulator, to enable it to locate and reach for objects by sight. Our system uses an affine stereo algorithm, a simple but robust approximation to the geometry of stereo vision, to estimate positions and surface orientations. It can be calibrated very easily with just four reference points. These are defined by the...

Hand-Eye Coordination Predicts Joint Attention.

The present article shows that infant and dyad differences in hand-eye coordination predict dyad differences in joint attention (JA). In the study reported here, 51 toddlers ranging in age from 11 to 24 months and their parents wore head-mounted eye trackers as they played with objects together. We found that physically active toddlers aligned their looking behavior with their parent and achiev...
