	abstract = {Humans successfully interact with their dynamic environment through a large repertoire of movements. Whether reaching out to an object, walking through a busy street, or even steering a car, humans actively move their eyes and head to direct their gaze to positions of interest, fostering movement planning and control. However, although the properties of the environment, and thus the positions of interest, can rapidly change, humans can direct their gaze only at one position at a time. Thus, the formation of gaze strategies for the visual guidance of actions is not trivial: One needs to efficiently select where to look next by exploiting prior knowledge and by considering future plans, by deciding whether and how much to engage the head, or by accounting for the temporal dynamics of the concurrent body action. Meanwhile, gaze deployment during natural behaviour is highly idiosyncratic, rendering the understanding of the underlying processes a challenging task. 

The proposed symposium will present recent advances about the aspects determining gaze deployment during the execution of (movement) tasks that vary in their level of complexity. We consider recent work extending from the lab to the world and from simple movements to whole-body actions, aiming to provide insights into the complex interplay between sensory and motor processes that govern the idiosyncratic nature of human visuomotor performance.

In detail, Dimitris Voudouris will talk about how gaze during manual actions is influenced by underlying sensorimotor uncertainty and noise, as these inherently increase during healthy aging. Jolande Fooken will present work on how humans use their eye movements to perform bimanual tasks, wherein several positions of interest need to be visually monitored at a time. Andrea Ghiani will continue to more complex, whole-body natural behaviour by presenting gaze control strategies when navigating staircases. The symposium will proceed with Christiane Wiebel-Herboth presenting eye and head deployment patterns during natural locomotion within a city landscape. The symposium will conclude with Otto Lappi talking about the gaze strategies employed during steering, and especially when timing constraints make the task critical.
