Target interception: hand-eye coordination and strategies.
This study was designed to define the characteristics of eye-hand coordination in a task requiring the interception of a moving target. It also assessed the extent to which the motion of the target was predicted and the strategies subjects used to determine when to initiate target interception. Target trajectories were constructed from sums of sines in the horizontal and vertical dimensions. Su...
متن کاملEye–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.
متن کاملActive Collisions in Altered Gravity Reveal Eye-Hand Coordination Strategies
Most object manipulation tasks involve a series of actions demarcated by mechanical contact events, and gaze is usually directed to the locations of these events as the task unfolds. Typically, gaze foveates the target 200 ms in advance of the contact. This strategy improves manual accuracy through visual feedback and the use of gaze-related signals to guide the hand/object. Many studies have i...
متن کاملEye movement accuracy determines natural interception strategies.
Eye movements aid visual perception and guide actions such as reaching or grasping. Most previous work on eye-hand coordination has focused on saccadic eye movements. Here we show that smooth pursuit eye movement accuracy strongly predicts both interception accuracy and the strategy used to intercept a moving object. We developed a naturalistic task in which participants (n = 42 varsity basebal...
متن کاملUncalibrated 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...
