Visual perception of motion integrates retinal and eye-movement signals. This study reveals that linear models explain illusions like the Aubert-Fleischl phenomenon, while some individuals exhibit non-linear speed encoding during eye movements.

Area of Science:

  • Neuroscience
  • Visual Perception
  • Computational Vision

Background:

  • Head-centered motion perception relies on integrating retinal and extra-retinal eye-velocity signals.
  • Illusions like the Aubert-Fleischl phenomenon and Filehne illusion suggest differences in how these signals encode speed.

Purpose of the Study:

  • To present a general model for head-centered motion perception, considering potential errors in both retinal and extra-retinal speed signals.
  • To investigate linear and non-linear speed transducer models to explain observed visual phenomena.

Main Methods:

  • Examined two types of speed transducers: linear and non-linear (power law-based).
  • Analyzed data from studies on the Aubert-Fleischl phenomenon and Filehne illusion.
  • Investigated general velocity-matching experiments.

Main Results:

  • The Aubert-Fleischl phenomenon and Filehne illusion are explained by linear speed transducers with a gain ratio less than one.
  • General velocity-matching is explained by linear models for some observers.
  • Non-linear behavior in some observers suggests expansive non-linearities in speed encoding.

Conclusions:

  • Linear speed transducers adequately describe motion perception illusions for most observers.
  • Non-linear speed encoding observed in some individuals offers new insights into head-centered motion perception strategies.
