Sequential stereopsis, a method for testing depth perception, demonstrated effective performance even with head movements. Observers often used a co-planarity strategy, influencing their depth judgments.

Area of Science:

  • Visual perception
  • Human factors engineering

Background:

  • The Enright sequential stereopsis paradigm assesses depth perception.
  • Previous studies focused on equidistance and co-planarity judgments.

Purpose of the Study:

  • To evaluate performance using sequential stereopsis under varying head positions and target configurations.
  • To investigate the strategies observers employ, specifically co-planarity, in depth perception tasks.
  • To test the validity of Enright's isovergence hypothesis.

Main Methods:

  • Utilized the sequential stereopsis paradigm with observers setting targets for equidistance and co-planarity.
  • Varied head position through rotations (azimuth, elevation, tilt) and target positions relative to the median plane.
  • Compared performance with simultaneous stereopsis and under restricted viewing conditions.

Main Results:

  • Sequential stereopsis yielded low disparity thresholds despite head rotations and off-median target placement.
  • Observer performance was robust, suggesting a co-planarity setting strategy was consistently used.
  • Results challenge the basic isovergence hypothesis, requiring extensions to account for eye position information.
  • Target settings formed a concave arc, quantitatively modeled by disparity correction for co-planarity tasks.

Conclusions:

  • Sequential stereopsis is a viable method for assessing depth perception, resilient to head movements.
  • Co-planarity is a dominant strategy in sequential stereopsis tasks, influencing perceived depth.
  • Existing models of stereopsis may need refinement to fully explain observed depth judgments.
