WebApr 26, 2024 · It is argued that fixation density, defined as the number of gaze points divided by the total area of a fixation event, can serve as a proxy for information processing and has a significant relationship with pupil data and fixation duration, which have been shown to be representative of cognitive effort and information processing. WebIn this work, we conduct two eye-tracking experiments involving 3D shapes, with both static and time-varying camera positions. We propose a method for mapping eye fixations (i.e., where humans gaze) onto the 3D shapes with the aim to produce a benchmark of 3D meshes with fixation density maps, which is publicly available. earth\u0027s tilt during seasons https://insegnedesign.com
