Timing of passage through an aperture between approaching people

The ability to perceive the motion of approaching person and to make appropriate adjustments to avoid collisions is an essential component of safe locomotion through the environment. The proposed project will investigate young and older adults’ collision avoidance behaviours with an approaching young adult in order to understand the visual information used to accomplish the task. The proposed research project will have two individuals approach an open doorway from opposite sides and pass through without colliding with each other. Both individuals’ movements will be tracked as they approach and pass through the doorway. The project will determine whether individuals use optical information, such as Time-to-Contact (TTC), to determine who will pass through the doorway first and avoid colliding with the other individual. It is believed that young adults will be in-tune with this optical information and use it to guide their actions whereas older adults may not use this information. The results from this project will help provide insights into any age-related behavioural changes and whether older adults are at a greater risk of collisions with other pedestrians in natural environments.
