It has applications in many areas, including psychological research and packaging design, but with regards to screen-based media, it’s primarily used by researchers to identify where users are looking.
What type of measure is eye tracking?
Eye trackers provide several measures of visual behavior that are relevant for understanding the interpretive process; these are categorically referred to as movement measures, position measures, numerosity measures, and latency measures (Holmqvist et al., 2011).
