5 –Vision in Hitting and Catching

How does an athlete get their glove, racquet, hand, or foot to the right place at the right time to hit, catch or strike a moving object? In this episode, I explore visual information that can be used to judge the time to contact and direction of motion of an approaching object and how it can be applied to the outfielder problem.   Research Confessions: The time I nearly published completely artifactual results   Links to articles discussed: The Black Cloud Lee’s 1976 paper Grasping tau Accuracy of estimating time to collision using binocular and monocular information Estimating the time to collision with a rotating nonspherical object The visual perception of motion in depth Catching a baseball: OAC How baseball outfielders determine where to run to catch fly balls Unconfounding the direction of motion in depth, time to passage and rotation rate of an approaching object Motion perception and driving: predicting performance through testing and shortening braking reaction times through training   IOVD Figure http://i110.photobucket.com/albums/n103/rgrayaction/IOVD%20Fig.jpg   More information http://www.perceptionactionpodcast.libsyn.com/ My Research Gate Page (pdfs of my articles) My ASU Web page Podcast Facebook page (videos, pics, etc) Twitter: @Shakeywaits Email: [email protected]   Credits: The Flamin' Groovies - Shake Some Action Between the Eyes – Christian Milone Catch Me, I’m Falling – Oblivion’s Garden Farmertan  - Ugly Truth   via freemusicarchive.org
