Abstract
To navigate complex environments, our gaze needs to attenuate to locomotor tasks, such as walking and turning. Shifting head and eye movements are critical and contribute to exploration of the world which is important when moving through different environments. The aim of my experiment is to characterize gaze in the context of turning. I hypothesize that older adults will shift their gaze in a new heading direction in anticipation of turns. Participants will be asked to navigate along a hallway consisting of a variety of turns to the left and right. Eye-tracking glasses will be worn by the participant in order to collect movement of the eyes. Participants will be fitted with 9 body-worn inertial sensors to record movements of the body segments. These sensors will be placed on the forehead, sternum, lumbar, shanks, feet, and wrists. Data from the hallway walks will be compared to gaze shifts during turning in standard clinical tests done in a laboratory to determine how different settings affect coordination of the head and eye movements. The study will allow us to emulate real-world settings and provide a foundation for understanding turns in older adults during daily activities.
