Gaze3D: Measuring gaze movements during experimentation of real physical experiments

We introduce a method and software to record and analyze three dimensional gaze movements of a freely moving subject during experimentation of a physical setup. A gaze - tracking helmet along with a head tracking unit combined using the open source library 'libGaze' pr ovides a world fixed gaze ray. The movement and intersection of this gaze ray with a digitized 3D representation of the physical setup is recorded. Afterwards it can be replayed and used to calculate 3D fixations on components, basis for further statistica l analysis. In this talk we will give an insight in the steps to conduct such an experiment. This example will illustrate the prospects and disadvantages of such an approach that can be used in a variety of research areas
