New disorientation illusions occur in tilted rooms with polarized objects. These reorientation illusions depend on visual scene displacement, most strongly when visual and body axes align, except when prone.

Area of Science:

  • Neuroscience
  • Human Perception
  • Vestibular System

Background:

  • Rotational illusions cause self-rotation perception.
  • Stationary tilted rooms induce limited illusory tilt.
  • Previous studies did not align body axis with room.
  • Disorientation illusions are common in altered visual environments.

Purpose of the Study:

  • Investigate new disorientation illusions in tilted rooms.
  • Examine illusions with polarized objects in 90°/180° tilted rooms.
  • Determine factors influencing reorientation illusions.

Main Methods:

  • Subjects in various body orientations (erect, supine, recumbent, inverted) were placed in 90°/180° tilted rooms.
  • Rooms contained familiar polarized objects.

  • Incidence of reorientation illusions was measured.
  • The 'levitation illusion' was observed in supine subjects.

    • Main Results:

    • A new class of disorientation illusions was revealed in tilted rooms with polarized objects.
    • Reorientation illusions are primarily driven by visual scene displacement, not body displacement.
    • Illusions are most likely when visual and body axes are congruent.
    • When axes are congruent, prone subjects experience fewer illusions than supine, recumbent, or inverted subjects.

    Conclusions:

    • Visual scene displacement is key to reorientation illusions in tilted environments.
    • Body posture significantly modulates the occurrence of these illusions.
    • Congruence between visual and body axes influences illusion likelihood, with proneness being a key differentiator.
