Robot-based Intervention to Improve Physical Activity in Older Adults

Recruited participants will be performing the JOGGNG Task on the Kinarm Endpoint Laboratory. This task requires participants to control a robotic handle to manipulate a virtual avatar that looks as if it is jogging across a field. During the jogging, a frisbee will appear and quickly move towards the avatar, eventually tilting clockwise or counterclockwise. Participants are required to either reach quickly to grab the frisbee from the air during clockwise tilts or to not move during counterclockwise tilts. This tilt/movement associated is reversed to control for a potential bias in tilt angle and movement. An image of physical activity or sedentary behaviour will appear inside of the frisbee but participants are not told that it is associated with any of the tilts. Each trial consists of one frisbee and participants will complete a total of 3 blocks of 360 trials each which will take approximately 30 minutes to complete.
