Abstract:
Previous work on eye-hand coordination has primarily focused on describing the timing and allocation of eye and hand movements when acting on single objects and in simple visual environments. However, in the real world we frequently engage in multi-tasking, for example, we perform an action while monitoring a visual scene, or we perform two actions simultaneously, both of which require accurate visuomotor control. In this talk, I will present a series of experiments that investigate patterns of eye-hand coordination in tasks that require gaze to be allocated to competing locations. The two main objectives of my talk will be (1) to pin down the functional role of gaze in goal-directed action and (2) to discover patterns of movement coordination in naturalistic tasks that require central vision at competing locations.I will provide evidence that gaze supports motor control by providing central vision of action-relevant locations and guiding the effector when contacting the environment. I will also show that hand movements, in turn, can be modulated such that gaze arrives at action-relevant locations at critical times. Thus, patterns of eye-hand coordination dynamically adapt with varying visuomotor demands and environmental structure.
