# Perceived depth reversals of images on a concave screen

## TL;DR

This paper explores how images on a concave screen can trick the brain into perceiving depth in the wrong direction.

## Contribution

A new type of depth reversal is demonstrated using a concave screen with multiple depth cues.

## Key findings

- Depth perception reverses when viewing images on a concave screen from certain distances.
- The reversal occurs even with familiar cues like shading and perspective.
- This effect is observed in binocular viewing conditions.

## Abstract

Reverspectives and hollow masks cause a reversal of perceived depth when observed from a position beyond certain critical distances, even if viewed binocularly. Their 3D structures or images invariably contain a linear perspective, shading, or familiarity cue to depth. Using a concave screen, we demonstrate a novel type of perceived depth reversal in binocular viewing with a variety of depth cues.
