Grasping in One-Handed Catching in Relation to Performance
Catching a flying ball involves bringing the hand to the aimed interception point at the right time, adjusting the hand posture to receive the incoming ball and to absorb the ball momentum, and closing the hand to ensure a stable grip. A small error in any of these actions can lead to a failure in catching the ball. Here we sought to gather new insights on what aspects of the catching movements...
متن کاملIntermittent vision and one-handed catching: the temporal limits of binocular and monocular integration.
The aim of this research was to examine the temporal limits of binocular and monocular integration useful for one-handed catching. Participants performed 20 one-handed catching trials in 12 conditions (N = 240) defined according to the type of viewing (binocular, monocular) and the manipulation of the visual sample (continuous, intermittent). Catching performance deteriorated significantly when...
متن کاملSimulation of Position Based Visual Control and Performance Tests of 6R Robot
This paper presents simulation and experimental results of position-based visual servoing control process of a 6R robot using 2 fixed cameras. This method has the ability to deal with real time changes in the relative position of the target-object with respect to robot. Also, greater accuracy and independency of servo control structure from the target pose coordinates are the additional advanta...
متن کاملHead Orientation position during birth and in infant neonatal period, and hand preference at nineteen weeks.
This study of lateral preferences of normal full-term infants found, as predicted, that infants who were delivered from a left occiput anterior or transverse birth position (head turned to the right) exhibited a neonatal right supine head orientation and a right-hand preference in visually guided reaching tasks at 19 weeks. Contrary to prediction, infants delivered from a right occiput anterior...
متن کاملEstimating 3D Hand Position and Orientation Using Stereo
We present an approach for estimating the 3D absolute position and orientation of the hand using a planar model of the back of the hand. We use stereo cameras to first build a sparse disparity map of the estimated area of the back of the hand. Then, the best fitting plane to the disparity points is computed using robust estimation. Finally, the 3D hand plane is calculated based on the disparity...
