Image fractal properties and their interaction with visual discomfort on gait kinematics

The aim of the current study was to investigate whether the fractal dimensions of an abstract scene affect a person's cognitive processing demands, using gait kinematics as a measure of cognitive demand. Participants (n=40) were asked to walk towards different types of synthetic images, which were parametrically varied in their fractal dimensions. At the end of each walk, participants rated each image for its visual discomfort (n=20) or for its likability (n=20). Datasets include 3D motion capture data as well as behavioural (image rating) data.
