Manual tracking enhances smooth pursuit eye movements.
Previous studies have reported that concurrent manual tracking enhances smooth pursuit eye movements only when tracking a self-driven or a predictable moving target. Here, we used a control-theoretic approach to examine whether concurrent manual tracking enhances smooth pursuit of an unpredictable moving target. In the eye-hand tracking condition, participants used their eyes to track a Gaussia...
متن کاملPerson Tracking, Pursuit & Interception by Mobile Robot
We present a method of tracking a human target whilst navigating in an unknown environment using a combination of visual and laser range sensing. The target’s legs detected by laser initialize both the pursuit process and modelling of target visual appearance. Intermittent recognition & tracking is possible using the learned visual model, as would likely occur in real pursuit scenarios when the...
متن کاملPredictive saccade in the absence of smooth pursuit: interception of moving targets in the archer fish.
Interception of fast-moving targets is a demanding task many animals solve. To handle it successfully, mammals employ both saccadic and smooth pursuit eye movements in order to confine the target to their area centralis. But how can non-mammalian vertebrates, which lack smooth pursuit, intercept moving targets? We studied this question by exploring eye movement strategies employed by archer fis...
متن کاملExtrapolation of visual motion for manual interception.
A frequent goal of hand movement is to touch a moving target or to make contact with a stationary object that is in motion relative to the moving head and body. This process requires a prediction of the target's motion, since the initial direction of the hand movement anticipates target motion. This experiment was designed to define the visual motion parameters that are incorporated in this pre...
متن کاملSpatial updating across saccades during manual interception.
We studied the effect of intervening saccades on the manual interception of a moving target. Previous studies suggest that stationary reach goals are coded and updated across saccades in gaze-centered coordinates, but whether this generalizes to interception is unknown. Subjects (n = 9) reached to manually intercept a moving target after it was rendered invisible. Subjects either fixated throug...
