Data from: An extensive dataset of eye movements during viewing of complex images

We present a dataset of free-viewing eye-movement recordings that contains
more than 2.7 million fixation locations from 949 observers on more than
1000 images from different categories. This dataset aggregates and
harmonizes data from 23 different studies conducted at the Institute of
Cognitive Science at Osnabrück University and the University Medical
Center in Hamburg-Eppendorf. Trained personnel recorded all studies under
standard conditions with homogeneous equipment and parameter settings. All
studies allowed for free eye-movements, and differed in the age range of
participants (~7-80 years), stimulus sizes, stimulus modifications (phase
scrambled, spatial filtering, mirrored), and stimuli categories (natural
and urban scenes, web sites, fractal, pink-noise, and ambiguous artistic
figures). The size and variability of viewing behavior within this dataset
presents a strong opportunity for evaluating and comparing computational
models of overt attention, and furthermore, for thoroughly quantifying
strategies of viewing behavior. This also makes the dataset a good
starting point for investigating whether viewing strategies change in
patient groups.
