Abstract

Although analysing software for eye-tracking data has improved a lot during the last decennia, analysis of gaze behaviour recorded using a head-mounted device is still challenging. In this paper gaze behaviour of six participants, cycling on four different roads, was analysed both Frame-by-Frame and on a fixation-based way. A Pearson correlation of 0.930 was found between the two methods, which points out good validity of the fixation-based analysing method. For the analysis of gaze behaviour over an extended period of time, the fixation-based approach can save a lot of processing time.
