Visualisation\nof fixation patterns<\/strong><\/h2>\n\n\n\n

Here we\npresent eye movement data recorded from 35 participants using Integration VR\nsystem. A first-person-view (FPV) with fixations was screened live on a large\nwall-mounted display (see illustration on home page). The online visualisation tool\noutputs a continuous stream of fixations and the fixations are accumulated over\ntime for the current stream to generate heat maps (fixation density at any given\nlocation). This can also be back-projected on the 3D model of the Mondrian\u2019s\nSalon, for a single or groups of observers at the same time for any chosen camera\npoint in virtual space. Further software options allow to track participants\u2019\nlocation in the room, their head positions, and gaze directions. <\/p>\n\n\n\n

The integration\nVR system can be used off-line to generate retrospective versions of live\nfeedback visualisations of individual and groups of  observers. Most importantly, the system provides\nquantitative gaze data for three dimensional regions of interest (\u2018colliders\u2019)\nwhich had been defined in the environment design: such as particular\nsub-regions on the walls covered with specific colour rectangles of prime\naesthetic interest – or regions outside of the room which are looked through\nwindows or doors. Altogether, a comprehensive description of participant\u2019s\nbehaviour during exploration of the virtual space is generated, and can be presented\nfor a single or several observers at the same time.<\/p>\n\n\n\n
