Although several theore tical frameworks have been proposed\, it is only recently that spatial sta tistics have begun to explore gaze patterns\, specifically by modelling fi xation locations as spatial point patterns arising from spatio-temporal po int processes. Inspired by the simple model of eye-movements proposed by Y litalo et al. in 2016\, we propose a stochastic model that incorporates bo th the semi-conscious transitions between regions of interest (ROIs) in a painting\, as well as the semi-random eye movements that occur while regis tering visual information within these regions during the first 30 seconds of art perception. \n \n\nUsing eye-tracking data from twenty subjects on six paintings\, we apply mean-shift clustering to identify ROIs in eac h painting based on the intensity of fixation points. A Markov chain is su bsequently used to model the transitions between these regions and based o n the model proposed by Ylitalo et al. we use the estimated intensity and saccade length distribution to model the placement of fixations within eac h ROI. Using this modelling approach\, we analyse the dynamics of eye move ments during the initial 30 seconds of art perception and to assess the ro bustness of our modelling assumptions across six diverse paintings and art istic styles.\n LOCATION:https://researchseminars.org/talk/gbgstats/87/ END:VEVENT END:VCALENDAR
